DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS [Abstract]
DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS L&F Acquisition Corp. (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on August 20, 2020. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities. On November 23, 2021, L&F Acquisition Holdings, LLC. (“Merger Sub”), a Delaware corporation and a wholly owned subsidiary of L&F Acquisition Corp., was formed. The Company is not limited to a particular industry or sector for purposes of consummating a business combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of March 31, 2022, the Company had not commenced any operations. All activity through March 31, 2022 relates to the Company’s identifying a target company for a business combination, and activities in connection with the proposed business combination with ZeroFox, Inc. (“ZeroFox”) and ID Experts Holdings, Inc. (“IDX” and, together with ZeroFox, the “Target Companies”) (the “Business Combination”). The Company will not generate any operating revenues until after the completion of the Business Combination or, if the Business Combination is not consummated, an alternative business combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The registration statement for the Company’s Initial Public Offering was declared effective on November 18, 2020. On November 23, 2020, the Company consummated the Initial Public Offering of 15,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units sold, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $150,000,000 which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated private placements of an aggregate of 6,859,505 warrants (the “Private Placement Warrants”) to JAR Sponsor, LLC (the “Sponsor”) and Jefferies LLC at a price of $1.00 per Private Placement Warrant and approximately $1.21 per Private Placement Warrant, respectively, generating gross proceeds of approximately $7,250,000, which are described in Note 4. On November 25, 2020, the underwriter fully exercised its over-allotment option, resulting in an additional 2,250,000 Units issued for an aggregate amount of $22,500,000. In connection with the underwriter’s full exercise of its over-allotment option, the Company also consummated the sale of an additional 728,925 Private Placement Warrants to the Sponsor and Jefferies LLC at $1.00 per Private Placement Warrant and approximately $1.21 per Private Placement Warrant, respectively, generating total proceeds of $787,500. A total of approximately $22,837,500 was deposited into the Trust Account, bringing the aggregate proceeds held in the Trust Account to approximately $175,087,500. Transaction costs amounted to $10,050,665, consisting of $3,450,000 of underwriting fees, $6,037,500 of deferred underwriting fees and $563,165 of other offering costs. Following the closing of the Initial Public Offering on November 23, 2020 and the underwriters full exercise of its over-allotment option on November 25, 2020, an amount of approximately $175,087,500 ($10.15 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”), and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earliest of: (i) the completion of a business combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a business combination. The stock exchange listing rules require that the business combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account). The Company will only complete a business combination if the post-business combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a business combination. The Company will provide the holders of the public shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination or an alternative business combination, either (i) in connection with a general meeting called to approve the Business Combination or an alternative business combination or (ii) by means of a tender offer. The Business Combination requires shareholder approval. In the event the Business Combination is not consummated, in connection with any alternative proposed business combination, the decision as to whether the Company will seek shareholder approval of an alternative business combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two The Company will proceed with a Business Combination only if the Company seeks shareholder approval, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who attend and vote at a general meeting of the Company. If a shareholder vote is not required and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to its amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each Public Shareholder may elect to redeem their Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent. The Sponsor has agreed (a) to waive its redemption rights with respect to any Founder Shares and Public Shares held by it in connection with the completion of a business combination and (b) not to propose an amendment to the amended and restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial business combination or to redeem 100% of the Public Shares if the Company does not complete a business combination within the Extended Combination Period (as defined below) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust account and not previously released to pay taxes, divided by the number of then issued and outstanding Public Shares. The Company previously had until May 23, 2022 to consummate a business combination. On May 3, 2022, the Company held an extraordinary general meeting of the shareholders pursuant to which its shareholders approved amending the Company’s memorandum and articles of association (the “Charter Amendment”) to extend the date by which the Company has to consummate a business combination from May 23, 2022 to August 24, 2022. The Company’s shareholders approved the Charter Amendment and as such the Company now has until August 24, 2022 to consummate a business combination (the “Extended Combination Period”). On May 3, 2022, the Company filed the Charter Amendment with the Registrar of Companies of the Cayman Islands. For further discussion of the Charter Amendment, please see the section titled Note 10 — Subsequent Events ten The Sponsor has agreed to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares it will receive if the Company fails to complete a business combination within the Extended Combination Period. However, if the Sponsor or any of its respective affiliates acquire Public Shares, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a business combination within the Extended Combination Period. The underwriter has agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a business combination within the Extended Combination Period, and in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than $10.15. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (1) $10.15 per Public Share and (2) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.15 per Public Share, due to reductions in the value of trust assets, in each case net of the interest that may be withdrawn to pay taxes. This liability will not apply to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and as to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Business Combination On December 17, 2021, L&F Acquisition Corp., a Cayman Islands exempted company (“LNFA”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among LNFA, L&F Acquisition Holdings, LLC, a Delaware limited liability company (“L&F Holdings”), ZF Merger Sub, Inc., a Delaware corporation (“ZF Merger Sub”), IDX Merger Sub, Inc., a Delaware corporation (“IDX Merger Sub”), IDX Forward Merger Sub, LLC, a Delaware limited liability company (“IDX Forward Merger Sub”), ZeroFox, Inc., a Delaware corporation (“ZeroFox”), and ID Experts Holdings, Inc., a Delaware corporation (“IDX”). The Business Combination Agreement and the transactions contemplated thereby were approved by the boards of directors of each of LNFA, ZeroFox and IDX and have been approved by the requisite stockholders of ZeroFox and IDX (See Note 6). Going Concern As of March 31, 2022, the Company had $263,247 in its operating bank accounts, $175,126,678 in marketable securities held in the Trust Account to be used for the Business Combination or an alternative business combination or to repurchase or redeem its common stock in connection therewith and working capital deficit of $4,313,633. The Company may need to raise additional capital through loans or additional investments from its Sponsor, stockholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. Additionally, In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the Company has until August 24, 2022 to consummate the Business Combination or a proposed alternative business combination. It is uncertain that the Company will be able to consummate the Business Combination or a proposed alternative business combination by this time. If the Business Combination or a proposed alternative business combination is not consummated by August 24, 2022, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the mandatory liquidation, should the Business Combination or a proposed alternative business combination not occur, potential subsequent dissolution, and working capital deficit raises substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after August 24, 2022.	NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS L&F Acquisition Corp. (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on August 20, 2020. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (a “Business Combination”). On November 23, 2021, L&F Acquisition Holdings, LLC. (“Merger Sub”), a Delaware corporation and a wholly owned subsidiary of L&F Acquisition Corp., was formed. The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of December 31, 2021, the Company had not commenced any operations. All activity from the period August 20, 2020 (inception) through December 31, 2021 relates to the Company’s identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end. The registration statement for the Company’s Initial Public Offering was declared effective on November 18, 2020. On November 23, 2020, the Company consummated the Initial Public Offering of 15,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units sold, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $150,000,000 which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated private placements of an aggregate of 6,859,505 warrants (the “Private Placement Warrants”) to JAR Sponsor, LLC (the “Sponsor”) and Jefferies LLC at a price of $1.00 per Private Placement Warrant and approximately $1.21 per Private Placement Warrant, respectively, generating gross proceeds of approximately $7,250,000, which are described in Note 4. On November 25, 2020, the underwriter fully exercised its over-allotment option, resulting in an additional 2,250,000 Units issued for an aggregate amount of $22,500,000. In connection with the underwriter’s full exercise of its over-allotment option, the Company also consummated the sale of an additional 728,925 Private Placement Warrants to the Sponsor and Jefferies LLC at $1.00 per Private Placement Warrant and approximately $1.21 per Private Placement Warrant, respectively, generating total proceeds of $787,500. A total of approximately $22,837,500 was deposited into the Trust Account, bringing the aggregate proceeds held in the Trust Account to approximately $175,087,500. Transaction costs amounted to $10,050,665, consisting of $3,450,000 of underwriting fees, $6,037,500 of deferred underwriting fees and $563,165 of other offering costs. Following the closing of the Initial Public Offering on November 23, 2020, and the underwriters full exercise of its over-allotment option on November 25, 2020, an amount of approximately $175,087,500 ($10.15 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”), and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earliest of: (i) the completion of a Business Combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The stock exchange listing rules require that the Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account). The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination. The Company will provide the holders of the public shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination, either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two The Company will proceed with a Business Combination only if the Company seeks shareholder approval, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of at least a majority of the shareholders who attend and vote at a general meeting of the Company. If a shareholder vote is not required and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to its amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each Public Shareholder may elect to redeem their Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent. The Sponsor has agreed (a) to waive its redemption rights with respect to any Founder Shares and Public Shares held by it in connection with the completion of a Business Combination and (b) not to propose an amendment to the amended and restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust account and not previously released to pay taxes, divided by the number of then issued and outstanding Public Shares. The Company will have until May 23, 2022 to consummate a Business Combination (the “Combination Period”). However, if the Company has not completed a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Public Shareholders and its Board of Directors, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period. The Sponsor has agreed to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares it will receive if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor or any of its respective affiliates acquire Public Shares, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriter has agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period, and in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than $10.15. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (1) $10.15 per Public Share and (2) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.15 per Public Share, due to reductions in the value of trust assets, in each case net of the interest that may be withdrawn to pay taxes. This liability will not apply to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and as to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Business Combination On December 17, 2021, L&F Acquisition Corp., a Cayman Islands exempted company (“LNFA”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among LNFA, L&F Acquisition Holdings, LLC, a Delaware limited liability company (“L&F Holdings”), ZF Merger Sub, Inc., a Delaware corporation (“ZF Merger Sub”), IDX Merger Sub, Inc., a Delaware corporation (“IDX Merger Sub”), IDX Forward Merger Sub, LLC, a Delaware limited liability company (“IDX Forward Merger Sub”), ZeroFox, Inc., a Delaware corporation (“ZeroFox”), and ID Experts Holdings, Inc., a Delaware corporation (“IDX”). The Business Combination Agreement and the transactions contemplated thereby were approved by the boards of directors of each of LNFA, ZeroFox and IDX and have been approved by the requisite stockholders of ZeroFox and IDX (See Note 6). Going Concern As of December 31, 2021, the Company had $575,739 in its operating bank accounts, $175,110,029 in marketable securities held in the Trust Account to be used for a Business Combination or to repurchase or redeem its common stock in connection therewith and working capital deficit of $2,550,274. The Company may need to raise additional capital through loans or additional investments from its Sponsor, stockholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. Additionally, In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the Company has until May 23, 2022 to consummate a Business Combination. It is uncertain that the Company will be able to consummate a Business Combination by this time. If a Business Combination is not consummated by this date and an extension not requested by the Sponsor, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the mandatory liquidation, should a Business Combination not occur and an extension is not requested by the Sponsor, potential subsequent dissolution, and working capital deficit raises substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after May 23, 2022.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed consolidated or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the period presented. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K, as filed with the SEC on March 14, 2022. The interim results for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the period ending December 31, 2022 or for any future periods. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of March 31, 2022 and December 31, 2021. Marketable Investments Held in Trust Account At March 31, 2022 and December 31, 2021, substantially all of the assets held in the Trust Account were held in a money market fund that only holds U.S. Treasury Securities. Offering Costs Offering costs consisted of legal, accounting and other expenses incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities were expensed as incurred in the condensed consolidated statements of operations. Offering costs associated with the Class A ordinary share issued were initially charged to temporary equity and then accreted to ordinary shares subject to redemption upon the completion of the Initial Public Offering. Offering costs amounting to $9,243,241 were charged to shareholders’ equity and offering costs amounting to $807,424 were charged to the statement of operations upon the completion of the Initial Public Offering (see Note 1). Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption are classified as a liability instrument and are measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March 31, 2022 and December 31, 2021, Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s condensed consolidated balance sheets. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable Class A ordinary shares resulted in charges against additional paid-in capital and accumulated deficit. At March 31, 2022 and December 31, 2021, the Class A ordinary shares reflected in the condensed Gross proceeds ​ ​ $175,087,500 Less: ​ ​ Proceeds allocated to Public Warrants ​ ​ (13,196,250) Class A ordinary shares issuance costs ​ ​ (9,243,241) Excess funds in trust from sale of Private Warrants ​ ​ (2,587,500) Plus: ​ ​ Accretion of carrying value to redemption value ​ ​ 25,026,991 Class A ordinary shares subject to possible redemption ​ ​ $175,087,500 Income Taxes The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2022 and December 31, 2021, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Net Income Per Ordinary Share The Company complies with accounting and disclosure requirements of the Financial Accounting Standards Board (“FASB”) ASC Topic 260, “Earnings Per Share”. Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value. The calculation of diluted income per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 16,213,430 Class A ordinary shares in the aggregate. As of March 31, 2022 and 2021, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the periods presented. The following table reflects the calculation of basic and diluted net income per ordinary share (in dollars, except per share amounts): ​ ​ For the Three Months Ended March 31, ​ ​ 2022 ​ ​ 2021 ​ ​ Class A ​ ​ Class B ​ ​ Class A ​ ​ Class B Basic and diluted net income per ordinary share ​ ​ ​ ​ ​ ​ ​ ​ Numerator: ​ ​ ​ ​ ​ ​ ​ ​ Allocation of net income, as adjusted ​ ​ $ 5,582,412 ​ ​ $1,395,603 ​ ​ $ 8,469,074 ​ ​ $ 2,117,268 Denominator: ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted average shares outstanding ​ ​ 17,250,000 ​ ​ 4,312,500 ​ ​ 17,250,000 ​ ​ 4,312,500 Basic and diluted net income per ordinary share ​ ​ $ 0.32 ​ ​ $ 0.32 ​ ​ $ 0.49 ​ ​ $ 0.49 Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the Company’s condensed consolidated balance sheet, primarily due to their short-term nature, other than warrant liabilities (see Note 9). Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The Company accounts for the Warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in the FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment. Recent Accounting Standards Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”). Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2021 and 2020. Marketable Investments Held in Trust Account At December 31, 2021 and 2020, substantially all of the assets held in the Trust Account were held in a money market fund that only holds U.S. Treasury Securities. Offering Costs Offering costs consisted of legal, accounting and other expenses incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities were expensed as incurred in the statements of operations. Offering costs associated with the Class A ordinary share issued were initially charged to temporary equity and then accreted to ordinary shares subject to redemption upon the completion of the Initial Public Offering. Offering costs amounting to $9,243,241 were charged to stockholders’ equity and offering costs amounting to $807,424 were charged to the statement of operations upon the completion of the Initial Public Offering (see Note 1). Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption are classified as a liability instrument and are measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at December 31, 2021 and 2020, Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheets. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable Class A ordinary shares resulted in charges against additional paid-in capital and accumulated deficit. At December 31, 2021, the Class A ordinary shares reflected in the balance sheets are reconciled in the following table: Gross proceeds ​ ​ $175,087,500 Less: ​ ​ Proceeds allocated to Public Warrants ​ ​ (13,196,250) Class A ordinary shares issuance costs ​ ​ (9,243,241) Excess funds in trust from sale of Private Warrants ​ ​ (2,587,500) Plus: ​ ​ Accretion of carrying value to redemption value ​ ​ 25,026,991 Class A ordinary shares subject to possible redemption ​ ​ $175,087,500 Income Taxes The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2021 and 2020, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Net Loss Per Ordinary Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share”. Net income (loss) per ordinary share is computed by dividing net income (loss) by the weighted average number of ordinary shares outstanding for the period. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value. The calculation of diluted income (loss) per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 16,213,430 Class A ordinary shares in the aggregate. As of December 31, 2021 and 2020, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the periods presented. The following table reflects the calculation of basic and diluted net income (loss) per ordinary share (in dollars, except per share amounts): ​ ​ Year Ended December 31, 2021 ​ ​ For the Period from August 20, 2020 (Inception) Through December 31, 2020 ​ ​ Class A ​ ​ Class B ​ ​ Class A ​ ​ Class B Basic and diluted net income (loss) per ordinary share ​ ​ ​ ​ ​ ​ ​ ​ Numerator: ​ ​ ​ ​ ​ ​ ​ ​ Allocation of net income (loss), as adjusted ​ ​ $ 4,478,469 ​ ​ $ 1,119,617 ​ ​ $(4,486,647) ​ ​ $(3,312,113) Denominator: ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted average shares outstanding ​ ​ 17,250,000 ​ ​ 4,312,500 ​ ​ 5,303,571 ​ ​ 3,915,179 Basic and diluted net income (loss) per ordinary share ​ ​ $ 0.26 ​ ​ $ 0.26 ​ ​ $ (0.85) ​ ​ $ (0.85) Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the Company’s balance sheet, primarily due to their short-term nature, other than warrant liabilities (see note 8). Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy.

Warrant Liability The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”).

The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment. Recent Accounting Standards In August 2020, the FASB issued ASU No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2020-06 effective as of January 1, 2021. The adoption of ASU 2020-06 did not have an impact on the Company’s consolidated financial statements. Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

RELATED PARTY TRANSACTIONS	NOTE 5 — RELATED PARTY TRANSACTIONS Founder Shares On August 28, 2020, the Sponsor paid $25,000 to cover certain offering and formation costs of the Company in consideration for 5,750,000 Class B ordinary shares (the “Founder Shares”). On November 13, 2020, the Sponsor effected a surrender of 1,437,500 Founder Shares to the Company for no consideration, resulting in a decrease in the total number of Class B ordinary shares outstanding to 4,312,500 shares. The Founder Shares included an aggregate of up to 562,500 shares that were subject to forfeiture depending on the extent to which the underwriter’s over-allotment option was exercised, so that the number of Founder Shares would equal, on an as-converted basis, approximately 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. As a result of the underwriter’s election to fully exercise their over-allotment option on November 25, 2020, no Founder Shares are currently subject to forfeiture. The Sponsor has agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earliest of: (A) one year after the completion of the Business Combination or a proposed alternative business combination and (B) subsequent to the Business Combination or a proposed alternative business combination, (x) if the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination or a proposed alternative business combination, or (y) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Public Shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property. Administrative Support Agreement Commencing on November 18, 2020, the Company entered into an agreement to pay the Sponsor up to $10,000 per month for office space, utilities, secretarial and administrative support services. Upon completion of the Business Combination or a proposed alternative business combination or its liquidation, the Company will cease paying these monthly fees. For each of the three months ended March 31, 2022 and 2021, the Company incurred and paid $30,000 in fees for these services. Related Party Loans In order to finance transaction costs in connection with the Business Combination or a proposed alternative business combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes the Business Combination or a proposed alternative business combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that the Business Combination or a proposed alternative business combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of the Business Combination or a proposed alternative business combination, without interest, or, at the lender’s discretion, up to $1,500,000 of such Working Capital Loans may be convertible into warrants of the post-Business Combination or proposed alternative business combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. As of March 31, 2022 and December 31, 2021, the Company had no outstanding borrowings under the Working Capital Loans.

COMMITMENTS AND CONTINGENCIES	NOTE 6 — COMMITMENTS AND CONTINGENCIES Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 global pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, its results of operations and/or search for a target company, the specific impact is not readily determinable as of the date of these condensed consolidated financial statements. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Registration and Shareholders Rights Pursuant to a registration and shareholders rights agreement entered into on November 23, 2020, the holders of the Founder Shares, Private Placement Warrants and any warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans) will have registration rights to require the Company to register a sale of any of securities held by them. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to completion of the Business Combination or a proposed alternative business combination. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The underwriter is entitled to a deferred fee of $0.35 per Unit, or $6,037,500 in the aggregate. The deferred fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that the Company completes the Business Combination or a proposed alternative business combination, subject to the terms of the underwriting agreement. Business Combination Agreement On December 17, 2021, L&F Acquisition Corp., a Cayman Islands exempted company (“LNFA”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among LNFA, L&F Acquisition Holdings, LLC, a Delaware limited liability company (“L&F Holdings”), ZF Merger Sub, Inc., a Delaware corporation (“ZF Merger Sub”), IDX Merger Sub, Inc., a Delaware corporation (“IDX Merger Sub”), IDX Forward Merger Sub, LLC, a Delaware limited liability company (“IDX Forward Merger Sub”), ZeroFox, Inc., a Delaware corporation (“ZeroFox”), and ID Experts Holdings, Inc., a Delaware corporation (“IDX”). The Business Combination Agreement and the transactions contemplated thereby were approved by the boards of directors of each of LNFA, ZeroFox and IDX and have been approved by the requisite stockholders of ZeroFox and IDX. The Business Combination Agreement provides for, among other things, the following transactions on the date of Closing: (i) ZF Merger Sub will merge with and into ZeroFox (the “ZF Merger”), with ZeroFox being the surviving company in the ZF Merger and, after giving effect to such merger, continuing as a wholly-owned subsidiary of L&F Holdings, (ii) IDX Merger Sub will merge with and into IDX (the “IDX Merger”), with IDX being the surviving company in the IDX Merger (“Transitional IDX Entity”) and, after giving effect to such merger, continuing as a wholly-owned subsidiary of L&F Holdings, and (iii) Transitional IDX Entity will merge with and into IDX Forward Merger Sub (the “IDX Forward Merger”, and collectively with the ZF Merger and IDX Merger, the “Mergers”), with IDX Forward Merger Sub being the surviving company in the IDX Forward Merger and, after giving effect to such merger, continuing as a wholly-owned subsidiary of L&F Holdings. The Mergers and the other transactions contemplated by the Business Combination Agreement are herein referred to as the Business Combination. The Business Combination is expected to close in the first half of 2022, following the receipt of the required approval by LNFA’s shareholders and the fulfillment of other customary closing conditions. Business Combination Consideration In accordance with the terms and subject to the conditions of the Business Combination Agreement, at the effective times of the Mergers, among other things, (i) each outstanding share of common stock (including shares of common stock issued upon the mandatory conversion of shares of preferred stock) of ZeroFox, other than ZF Dissenting Shares (as defined in the Business Combination Agreement) and ZF Cancelled Shares (as defined in the Business Combination Agreement), will be automatically cancelled and converted into a right to receive a fraction of a share of LNFA Common Stock determined in accordance with the Business Combination Agreement on the basis of a pre-money enterprise value of ZeroFox of $866,250,000 and a price of $10.00 per share of LNFA Common Stock and (ii) each outstanding share of common stock and preferred stock of IDX, other than IDX Dissenting Shares (as defined in the Business Combination Agreement) and IDX Cancelled Shares (as defined in the Business Combination Agreement), will be automatically cancelled and converted into a right to receive (x) for common stock and series a-1 and series a-2 preferred stock, a fraction of a share of LNFA Common Stock, (y) for common stock and series a-1 and series a-2 preferred stock, a portion of $50,000,000 in cash consideration (subject to certain adjustments for cash, working capital, debt and transaction expenses, and net of liquidation preferences, as provided in the Business Combination Agreement), and (z) for series a-1, series a-2 and series b preferred stock, a liquidation preference amount of $0.361, in each case, in accordance with the Business Combination Agreement and on the basis of a pre-money enterprise value of IDX of $338,750,000 and a price of $10.00 per share of LNFA Common Stock. Advisory Services The Company entered into an advisory agreement with Jefferies LLC (“Jefferies”). Jeffries will act as (i) the Company’s exclusive financial advisor and exclusive capital markets advisor in connection with the Business Combination involving one or both of the Target Companies and (ii) sole and exclusive (other than with respect to Stifel Financial Corp. (“Stifel”). If the pending Business Combination with ZeroFox and/or IDX does not occur, the Company will not be required to pay any contingent fees in connection with this agreement. Jefferies will provide the Company with mergers and acquisition and equity capital markets financial advice and assistance in connection with a possible acquisition or other business transaction or series of transactions involving all or a material portion of the Target’s equity or assets, whether directly or indirectly and through any form of transaction, including, without limitation, merger, reverse merger, liquidation, stock purchase, asset purchase, recapitalization, reorganization, consolidation, amalgamation, joint venture, strategic partnership, license or other transaction. The Company entered into an agreement with Stifel, Nicolaus & Company, Incorporated (“Stifel”). Stifel will endeavor to obtain one or more commitments for the Financing (individually a “Commitment” and collectively the “Commitments”) from one or more financial institutions or other sources other than any affiliates of the Company, ZeroFOX or IDX. (the “Investors”). If the Business Combination does not occur, the Company will not be required to pay any contingent fees in connection with this agreement. There can be no assurances that the Company will complete the pending Business Combination with ZeroFox and/or IDX. Common Equity Investment Concurrently with the execution of the Business Combination Agreement, LNFA entered into subscription agreements (the “Common Equity Subscription Agreements”) with certain investors, including, among others, Victory Park Capital, certain existing stockholders of ZeroFox (certain funds affiliated with New Enterprise Associates, Highland Capital and Alsop Louie Partners (the “ZF Investors”)), and certain existing stockholders of IDX (certain funds affiliated with Blue Venture Fund, Peloton Equity and ForgePoint Capital (the “IDX Investors”)). Pursuant to the Common Equity Subscription Agreements, the investors agreed to subscribe for and purchase, and LNFA agreed to issue and sell to such investors, on the Closing Date (as defined in the Business Combination Agreement), an aggregate of 2,000,000 shares of LNFA Common Stock in exchange for an aggregate purchase price of $20,000,000 (the “Common Equity PIPE Financing”). In addition, on December 16, 2021, the ZF Investors purchased PIK promissory notes issued by ZeroFox (the “ZF PIK Promissory Notes”) for an aggregate purchase price of $5,000,000. Such ZF PIK Promissory Notes accrue interest that will be paid-in-kind at a rate of 5.0% per annum. If the Closing occurs, the repayment of the original principal amount of the ZF PIK Promissory Notes may be offset against amounts owed by the ZF investors under their Common Equity Subscription Agreements. In addition, if the Closing occurs, any portion of closing cash consideration to which the IDX Investors are entitled in connection with the consummation of the Business Combination may be reduced to fund the subscription amount the IDX Investors would otherwise be required to pay pursuant to the Common Equity Subscription Agreements. The closing of the Common Equity PIPE Financing is contingent upon, among other things, the substantially concurrent consummation of the Business Combination. The Common Equity Subscription Agreements provide that LNFA will grant the investors in the Common Equity PIPE Financing certain customary registration rights. Convertible Notes Investment In connection with signing the Business Combination Agreement, LNFA entered into convertible note subscription agreements (the “Convertible Note Subscription Agreements”) with affiliates of Monarch Alternative Capital LP, Victory Park Capital and Corbin Capital (the “Note Investors”), in respect of $150,000,000 aggregate principal amount of unsecured convertible notes due in 2025 (the “Notes”) to be issued in connection with the closing of the Business Combination (the “Convertible Notes Financing”). The principal terms of the Notes are set forth in the form of indenture attached as an exhibit to the Convertible Note Subscription Agreements, which indenture shall be entered into by LNFA, the guarantors party thereto and the indenture trustee (the “Indenture”), and the form of global note attached thereto. The Notes will bear interest at a rate of 7.00% per annum, payable quarterly in cash; provided, that the issuer may elect to pay interest in kind at 8.75% per annum, and the Notes will be convertible at an initial conversion price of $11.50, subject to customary anti-dilution adjustments, including with respect to stock-splits and stock dividends, dividends and other distributions, above-market tender offers, below-market rights offerings and spin-offs (the “Conversion Price”), and shall mature on the date that is three years following the closing of the Convertible Notes Financing. The post-Business Combination company may, at its election, force conversion of the Notes after the first anniversary of the issuance of the Notes (the “Conversion Trigger Date”), subject to a holder’s prior right to convert, if the volume-weighted average trading price of the post-Business Combination company’s common stock (x) for the first year after the Conversion Trigger Date, is greater than or equal to 150% of the conversion price for more than 20 trading days during a period of 30 consecutive trading days and (y) for the second year after the Conversion Trigger Date, is greater than or equal to 130% of the conversion price for more than 20 trading days during a period of 30 consecutive trading days. Each holder of a Note will have the right to cause the post-Business Combination company to repurchase for cash all or a portion of the Notes held by such holder at any time upon the occurrence of a “fundamental change”, a customary definition provided in the Indenture (a “Fundamental Change”), at a price equal to par plus accrued and unpaid interest. In the event of a conversion in connection with a Fundamental Change, the Conversion Price will be adjusted by a usual and customary Fundamental Change “make-whole table” to be agreed in the Indenture. The Indenture will include restrictive covenants that, among other things, will limit the ability of the post-Business Combination company to incur senior debt in excess of $50,000,000, subject to certain qualifications and exceptions set forth in the Indenture. The Indenture also will include customary events of default. The closing of the Convertible Notes Financing is contingent upon, among other things, the substantially concurrent consummation of the Business Combination. LNFA has agreed to execute a registration rights agreement for the benefit of the Note Investors, providing for customary demand, shelf and piggyback registration rights and otherwise in form and substance acceptable to the Note Investors and LNFA.

WARRANTS (Q1)

WARRANTS (Q1)	3 Months Ended	12 Months Ended

WARRANTS [Abstract]
WARRANTS	NOTE 8 — WARRANTS At March 31, 2022 and December 31, 2021, there were 8,625,000 Public Warrants and 7,588,430 Private Placement Warrants, respectively outstanding. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of the Business Combination or a proposed alternative business combination and (b) one year from the closing of the Initial Public Offering. The Public Warrants will expire five years from the completion of the Business Combination or a proposed alternative business combination or earlier upon redemption or liquidation. The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary share issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. The Company has agreed that as soon as practicable, but in no event later than 20 business days, after the closing of the Business Combination or a proposed alternative business combination it will use its best efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants. The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement and a current prospectus relating thereto until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the sixtieth (60th) business day after the closing of the Business Combination or a proposed alternative business combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.01 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; and • if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders. If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.10 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined based on the redemption date and the fair market value of the Class A ordinary shares; • if, and only if, the closing price of the Class A ordinary shares equal or exceeds $10.00 per public share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company send the notice of redemption of the warrant holders; and • if the closing price of the Class A ordinary shares for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants. If the Company calls the Public Warrants for redemption, as described above, its management will have the option to require any holder that wishes to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of ordinary shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for issuances of ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the Public Warrants. If the Company is unable to complete the Business Combination or a proposed alternative business combination within the Extended Combination Period and the Company liquidates the funds held in the Trust Account, holders of Public Warrants will not receive any of such funds with respect to their Public Warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such Public Warrants. Accordingly, the Public Warrants may expire worthless. In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the Business Combination or a proposed alternative business combination at an issue price or effective issue price of less than $9.20 per Class A ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the Business Combination or a proposed alternative business combination on the date of the consummation of the Business Combination or a proposed alternative business combination (net of redemptions), and (z) the volume weighted average trading price of the Class A ordinary shares during the 10 trading day period starting on the trading day prior to the day on which the Company consummates the Business Combination or a proposed alternative business combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price. The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of the Business Combination or a proposed alternative business combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable, except as described above, so long as they are held by the initial purchasers, Jefferies LLC or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers, Jefferies LLC or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. Further, in accordance with FINRA Rule 5110(g)(8)(A), the Private Placement Warrants purchased by Jefferies LLC will not be exercisable for more than five years from the effective date of the registration statement filed in connection with the Company’s Initial Public Offering for so long as they are held by the Jefferies LLC.	NOTE 8 —WARRANTS At December 31, 2021 and 2020, there were 8,625,000 Public Warrants and 7,588,430 Private Placement Warrants, respectively outstanding. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination and (b) one year from the closing of the Initial Public Offering. The Public Warrants will expire five years from the completion of a Business Combination or earlier upon redemption or liquidation. The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary share issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. The Company has agreed that as soon as practicable, but in no event later than 20 business days, after the closing of a Business Combination, it will use its best efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants. The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement and a current prospectus relating thereto until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the sixtieth (60th) business day after the closing of a Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.01 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; and • if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders. If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.10 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined based on the redemption date and the fair market value of the Class A ordinary shares; • if, and only if, the closing price of the Class A ordinary shares equal or exceeds $10.00 per public share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company send the notice of redemption of the warrant holders; and • if the closing price of the Class A ordinary shares for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants. If the Company calls the Public Warrants for redemption, as described above, its management will have the option to require any holder that wishes to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of ordinary shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for issuances of ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the Public Warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of Public Warrants will not receive any of such funds with respect to their Public Warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such Public Warrants. Accordingly, the Public Warrants may expire worthless. In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at an issue price or effective issue price of less than $9.20 per Class A ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of a Business Combination on the date of the consummation of a Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Class A ordinary shares during the 10 trading day period starting on the trading day prior to the day on which the Company consummates a Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price. The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable, except as described above, so long as they are held by the initial purchasers, Jefferies LLC or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers, Jefferies LLC or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. Further, in accordance with FINRA Rule 5110(g)(8)(A), the Private Placement Warrants purchased by Jefferies LLC will not be exercisable for more than five years from the effective date of the registration statement filed in connection with the Company’s Initial Public Offering for so long as they are held by the Jefferies LLC.

FAIR VALUE MEASUREMENTS [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 9 — FAIR VALUE MEASUREMENTS The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability. At March 31, 2022 and December 31, 2021, assets held in the Trust Account were comprised of $175,126,678 and $175,110,029, respectively in a money market fund which is invested in U.S. Treasury Securities. During March 31, 2022 and December 31, 2021, the Company did not withdraw any interest income from the Trust Account. The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at March 31, 2022 and December 31, 2021 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value.

The estimated fair value of the Public Warrants transferred from a Level 3 measurement to a Level 1 fair value measurement during the year ended December 31, 2021 was $6,028,013. The following table presents the changes in the fair value of Level 3 warrant liabilities at March 31, 2022 and March 31, 2021: Fair value as of December 31, 2021 ​ ​ $ 12,609,407 Change in fair value ​ ​ (5,327,337) Fair value as of March 31, 2022 ​ ​ $ 7,282,070 ​ ​ Fair value as of December 31, 2020 ​ ​ $ 28,062,924 Change in fair value ​ ​ (10,825,645) Transfer of Public warrants to level 1 ​ ​ (5,778,750) Fair value as of March 31, 2021 ​ ​ $ 11,458,529 The Private Warrants were valued as of November 23, 2020 and subsequent periods using a Modified Black Scholes Option Pricing Model, which is considered to be a Level 3 fair value measurement. The Modified Black Scholes model’s primary unobservable input utilized in determining the fair value of the Private Warrants is the expected volatility of the ordinary shares. The expected volatility as of the Initial Public Offering date was derived from observable public warrant pricing on comparable ‘blank-check’ companies without an identified target. The expected volatility as of subsequent valuation dates was implied from the Company’s own public warrant pricing. A Monte Carlo simulation methodology was used in estimating the fair value of the Public Warrants as of November 23, 2020 and December 31, 2020, for periods where no observable traded price was available, using the same expected volatility as was used in measuring the fair value of the Private Warrants. For periods subsequent to the detachment of the Public Warrants from the Units, the close price of the Public Warrant price was used as the fair value as of each relevant date. The key inputs into the Black-Scholes-Merton model for the Private Placement Warrants were as follows: Input ​ ​ March 31, 2022 ​ ​ December 31, 2021 Risk-free interest rate ​ ​ 2.42% ​ ​ 1.26% Trading days per year ​ ​ 252 ​ ​ 252 Volatility ​ ​ 11.0% ​ ​ 22.0% Exercise price ​ ​ $ 11.50 ​ ​ $11.50 Stock Price ​ ​ $10.12 ​ ​ $10.03	NOTE 9 — FAIR VALUE MEASUREMENTS The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date.

DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS [Abstract]
DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS L&F Acquisition Corp. (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on August 20, 2020. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities. On November 23, 2021, L&F Acquisition Holdings, LLC. (“Merger Sub”), a Delaware corporation and a wholly owned subsidiary of L&F Acquisition Corp., was formed. The Company is not limited to a particular industry or sector for purposes of consummating a business combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of March 31, 2022, the Company had not commenced any operations. All activity through March 31, 2022 relates to the Company’s identifying a target company for a business combination, and activities in connection with the proposed business combination with ZeroFox, Inc. (“ZeroFox”) and ID Experts Holdings, Inc. (“IDX” and, together with ZeroFox, the “Target Companies”) (the “Business Combination”). The Company will not generate any operating revenues until after the completion of the Business Combination or, if the Business Combination is not consummated, an alternative business combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The registration statement for the Company’s Initial Public Offering was declared effective on November 18, 2020. On November 23, 2020, the Company consummated the Initial Public Offering of 15,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units sold, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $150,000,000 which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated private placements of an aggregate of 6,859,505 warrants (the “Private Placement Warrants”) to JAR Sponsor, LLC (the “Sponsor”) and Jefferies LLC at a price of $1.00 per Private Placement Warrant and approximately $1.21 per Private Placement Warrant, respectively, generating gross proceeds of approximately $7,250,000, which are described in Note 4. On November 25, 2020, the underwriter fully exercised its over-allotment option, resulting in an additional 2,250,000 Units issued for an aggregate amount of $22,500,000. In connection with the underwriter’s full exercise of its over-allotment option, the Company also consummated the sale of an additional 728,925 Private Placement Warrants to the Sponsor and Jefferies LLC at $1.00 per Private Placement Warrant and approximately $1.21 per Private Placement Warrant, respectively, generating total proceeds of $787,500. A total of approximately $22,837,500 was deposited into the Trust Account, bringing the aggregate proceeds held in the Trust Account to approximately $175,087,500. Transaction costs amounted to $10,050,665, consisting of $3,450,000 of underwriting fees, $6,037,500 of deferred underwriting fees and $563,165 of other offering costs. Following the closing of the Initial Public Offering on November 23, 2020 and the underwriters full exercise of its over-allotment option on November 25, 2020, an amount of approximately $175,087,500 ($10.15 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”), and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earliest of: (i) the completion of a business combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a business combination. The stock exchange listing rules require that the business combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account). The Company will only complete a business combination if the post-business combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a business combination. The Company will provide the holders of the public shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination or an alternative business combination, either (i) in connection with a general meeting called to approve the Business Combination or an alternative business combination or (ii) by means of a tender offer. The Business Combination requires shareholder approval. In the event the Business Combination is not consummated, in connection with any alternative proposed business combination, the decision as to whether the Company will seek shareholder approval of an alternative business combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two The Company will proceed with a Business Combination only if the Company seeks shareholder approval, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who attend and vote at a general meeting of the Company. If a shareholder vote is not required and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to its amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each Public Shareholder may elect to redeem their Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent. The Sponsor has agreed (a) to waive its redemption rights with respect to any Founder Shares and Public Shares held by it in connection with the completion of a business combination and (b) not to propose an amendment to the amended and restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial business combination or to redeem 100% of the Public Shares if the Company does not complete a business combination within the Extended Combination Period (as defined below) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust account and not previously released to pay taxes, divided by the number of then issued and outstanding Public Shares. The Company previously had until May 23, 2022 to consummate a business combination. On May 3, 2022, the Company held an extraordinary general meeting of the shareholders pursuant to which its shareholders approved amending the Company’s memorandum and articles of association (the “Charter Amendment”) to extend the date by which the Company has to consummate a business combination from May 23, 2022 to August 24, 2022. The Company’s shareholders approved the Charter Amendment and as such the Company now has until August 24, 2022 to consummate a business combination (the “Extended Combination Period”). On May 3, 2022, the Company filed the Charter Amendment with the Registrar of Companies of the Cayman Islands. For further discussion of the Charter Amendment, please see the section titled Note 10 — Subsequent Events ten The Sponsor has agreed to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares it will receive if the Company fails to complete a business combination within the Extended Combination Period. However, if the Sponsor or any of its respective affiliates acquire Public Shares, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a business combination within the Extended Combination Period. The underwriter has agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a business combination within the Extended Combination Period, and in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than $10.15. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (1) $10.15 per Public Share and (2) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.15 per Public Share, due to reductions in the value of trust assets, in each case net of the interest that may be withdrawn to pay taxes. This liability will not apply to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and as to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Business Combination On December 17, 2021, L&F Acquisition Corp., a Cayman Islands exempted company (“LNFA”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among LNFA, L&F Acquisition Holdings, LLC, a Delaware limited liability company (“L&F Holdings”), ZF Merger Sub, Inc., a Delaware corporation (“ZF Merger Sub”), IDX Merger Sub, Inc., a Delaware corporation (“IDX Merger Sub”), IDX Forward Merger Sub, LLC, a Delaware limited liability company (“IDX Forward Merger Sub”), ZeroFox, Inc., a Delaware corporation (“ZeroFox”), and ID Experts Holdings, Inc., a Delaware corporation (“IDX”). The Business Combination Agreement and the transactions contemplated thereby were approved by the boards of directors of each of LNFA, ZeroFox and IDX and have been approved by the requisite stockholders of ZeroFox and IDX (See Note 6). Going Concern As of March 31, 2022, the Company had $263,247 in its operating bank accounts, $175,126,678 in marketable securities held in the Trust Account to be used for the Business Combination or an alternative business combination or to repurchase or redeem its common stock in connection therewith and working capital deficit of $4,313,633. The Company may need to raise additional capital through loans or additional investments from its Sponsor, stockholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. Additionally, In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the Company has until August 24, 2022 to consummate the Business Combination or a proposed alternative business combination. It is uncertain that the Company will be able to consummate the Business Combination or a proposed alternative business combination by this time. If the Business Combination or a proposed alternative business combination is not consummated by August 24, 2022, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the mandatory liquidation, should the Business Combination or a proposed alternative business combination not occur, potential subsequent dissolution, and working capital deficit raises substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after August 24, 2022.	NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS L&F Acquisition Corp. (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on August 20, 2020. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (a “Business Combination”). On November 23, 2021, L&F Acquisition Holdings, LLC. (“Merger Sub”), a Delaware corporation and a wholly owned subsidiary of L&F Acquisition Corp., was formed. The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of December 31, 2021, the Company had not commenced any operations. All activity from the period August 20, 2020 (inception) through December 31, 2021 relates to the Company’s identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end. The registration statement for the Company’s Initial Public Offering was declared effective on November 18, 2020. On November 23, 2020, the Company consummated the Initial Public Offering of 15,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units sold, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $150,000,000 which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated private placements of an aggregate of 6,859,505 warrants (the “Private Placement Warrants”) to JAR Sponsor, LLC (the “Sponsor”) and Jefferies LLC at a price of $1.00 per Private Placement Warrant and approximately $1.21 per Private Placement Warrant, respectively, generating gross proceeds of approximately $7,250,000, which are described in Note 4. On November 25, 2020, the underwriter fully exercised its over-allotment option, resulting in an additional 2,250,000 Units issued for an aggregate amount of $22,500,000. In connection with the underwriter’s full exercise of its over-allotment option, the Company also consummated the sale of an additional 728,925 Private Placement Warrants to the Sponsor and Jefferies LLC at $1.00 per Private Placement Warrant and approximately $1.21 per Private Placement Warrant, respectively, generating total proceeds of $787,500. A total of approximately $22,837,500 was deposited into the Trust Account, bringing the aggregate proceeds held in the Trust Account to approximately $175,087,500. Transaction costs amounted to $10,050,665, consisting of $3,450,000 of underwriting fees, $6,037,500 of deferred underwriting fees and $563,165 of other offering costs. Following the closing of the Initial Public Offering on November 23, 2020, and the underwriters full exercise of its over-allotment option on November 25, 2020, an amount of approximately $175,087,500 ($10.15 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”), and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earliest of: (i) the completion of a Business Combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The stock exchange listing rules require that the Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account). The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination. The Company will provide the holders of the public shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination, either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two The Company will proceed with a Business Combination only if the Company seeks shareholder approval, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of at least a majority of the shareholders who attend and vote at a general meeting of the Company. If a shareholder vote is not required and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to its amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each Public Shareholder may elect to redeem their Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent. The Sponsor has agreed (a) to waive its redemption rights with respect to any Founder Shares and Public Shares held by it in connection with the completion of a Business Combination and (b) not to propose an amendment to the amended and restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust account and not previously released to pay taxes, divided by the number of then issued and outstanding Public Shares. The Company will have until May 23, 2022 to consummate a Business Combination (the “Combination Period”). However, if the Company has not completed a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Public Shareholders and its Board of Directors, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period. The Sponsor has agreed to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares it will receive if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor or any of its respective affiliates acquire Public Shares, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriter has agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period, and in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than $10.15. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (1) $10.15 per Public Share and (2) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.15 per Public Share, due to reductions in the value of trust assets, in each case net of the interest that may be withdrawn to pay taxes. This liability will not apply to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and as to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Business Combination On December 17, 2021, L&F Acquisition Corp., a Cayman Islands exempted company (“LNFA”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among LNFA, L&F Acquisition Holdings, LLC, a Delaware limited liability company (“L&F Holdings”), ZF Merger Sub, Inc., a Delaware corporation (“ZF Merger Sub”), IDX Merger Sub, Inc., a Delaware corporation (“IDX Merger Sub”), IDX Forward Merger Sub, LLC, a Delaware limited liability company (“IDX Forward Merger Sub”), ZeroFox, Inc., a Delaware corporation (“ZeroFox”), and ID Experts Holdings, Inc., a Delaware corporation (“IDX”). The Business Combination Agreement and the transactions contemplated thereby were approved by the boards of directors of each of LNFA, ZeroFox and IDX and have been approved by the requisite stockholders of ZeroFox and IDX (See Note 6). Going Concern As of December 31, 2021, the Company had $575,739 in its operating bank accounts, $175,110,029 in marketable securities held in the Trust Account to be used for a Business Combination or to repurchase or redeem its common stock in connection therewith and working capital deficit of $2,550,274. The Company may need to raise additional capital through loans or additional investments from its Sponsor, stockholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. Additionally, In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the Company has until May 23, 2022 to consummate a Business Combination. It is uncertain that the Company will be able to consummate a Business Combination by this time. If a Business Combination is not consummated by this date and an extension not requested by the Sponsor, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the mandatory liquidation, should a Business Combination not occur and an extension is not requested by the Sponsor, potential subsequent dissolution, and working capital deficit raises substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after May 23, 2022.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed consolidated or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the period presented. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K, as filed with the SEC on March 14, 2022. The interim results for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the period ending December 31, 2022 or for any future periods. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of March 31, 2022 and December 31, 2021. Marketable Investments Held in Trust Account At March 31, 2022 and December 31, 2021, substantially all of the assets held in the Trust Account were held in a money market fund that only holds U.S. Treasury Securities. Offering Costs Offering costs consisted of legal, accounting and other expenses incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities were expensed as incurred in the condensed consolidated statements of operations. Offering costs associated with the Class A ordinary share issued were initially charged to temporary equity and then accreted to ordinary shares subject to redemption upon the completion of the Initial Public Offering. Offering costs amounting to $9,243,241 were charged to shareholders’ equity and offering costs amounting to $807,424 were charged to the statement of operations upon the completion of the Initial Public Offering (see Note 1). Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption are classified as a liability instrument and are measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March 31, 2022 and December 31, 2021, Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s condensed consolidated balance sheets. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable Class A ordinary shares resulted in charges against additional paid-in capital and accumulated deficit. At March 31, 2022 and December 31, 2021, the Class A ordinary shares reflected in the condensed Gross proceeds ​ ​ $175,087,500 Less: ​ ​ Proceeds allocated to Public Warrants ​ ​ (13,196,250) Class A ordinary shares issuance costs ​ ​ (9,243,241) Excess funds in trust from sale of Private Warrants ​ ​ (2,587,500) Plus: ​ ​ Accretion of carrying value to redemption value ​ ​ 25,026,991 Class A ordinary shares subject to possible redemption ​ ​ $175,087,500 Income Taxes The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2022 and December 31, 2021, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Net Income Per Ordinary Share The Company complies with accounting and disclosure requirements of the Financial Accounting Standards Board (“FASB”) ASC Topic 260, “Earnings Per Share”. Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value. The calculation of diluted income per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 16,213,430 Class A ordinary shares in the aggregate. As of March 31, 2022 and 2021, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the periods presented. The following table reflects the calculation of basic and diluted net income per ordinary share (in dollars, except per share amounts): ​ ​ For the Three Months Ended March 31, ​ ​ 2022 ​ ​ 2021 ​ ​ Class A ​ ​ Class B ​ ​ Class A ​ ​ Class B Basic and diluted net income per ordinary share ​ ​ ​ ​ ​ ​ ​ ​ Numerator: ​ ​ ​ ​ ​ ​ ​ ​ Allocation of net income, as adjusted ​ ​ $ 5,582,412 ​ ​ $1,395,603 ​ ​ $ 8,469,074 ​ ​ $ 2,117,268 Denominator: ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted average shares outstanding ​ ​ 17,250,000 ​ ​ 4,312,500 ​ ​ 17,250,000 ​ ​ 4,312,500 Basic and diluted net income per ordinary share ​ ​ $ 0.32 ​ ​ $ 0.32 ​ ​ $ 0.49 ​ ​ $ 0.49 Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the Company’s condensed consolidated balance sheet, primarily due to their short-term nature, other than warrant liabilities (see Note 9). Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The Company accounts for the Warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in the FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment. Recent Accounting Standards Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”). Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2021 and 2020. Marketable Investments Held in Trust Account At December 31, 2021 and 2020, substantially all of the assets held in the Trust Account were held in a money market fund that only holds U.S. Treasury Securities. Offering Costs Offering costs consisted of legal, accounting and other expenses incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities were expensed as incurred in the statements of operations. Offering costs associated with the Class A ordinary share issued were initially charged to temporary equity and then accreted to ordinary shares subject to redemption upon the completion of the Initial Public Offering. Offering costs amounting to $9,243,241 were charged to stockholders’ equity and offering costs amounting to $807,424 were charged to the statement of operations upon the completion of the Initial Public Offering (see Note 1). Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption are classified as a liability instrument and are measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at December 31, 2021 and 2020, Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheets. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable Class A ordinary shares resulted in charges against additional paid-in capital and accumulated deficit. At December 31, 2021, the Class A ordinary shares reflected in the balance sheets are reconciled in the following table: Gross proceeds ​ ​ $175,087,500 Less: ​ ​ Proceeds allocated to Public Warrants ​ ​ (13,196,250) Class A ordinary shares issuance costs ​ ​ (9,243,241) Excess funds in trust from sale of Private Warrants ​ ​ (2,587,500) Plus: ​ ​ Accretion of carrying value to redemption value ​ ​ 25,026,991 Class A ordinary shares subject to possible redemption ​ ​ $175,087,500 Income Taxes The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2021 and 2020, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Net Loss Per Ordinary Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share”. Net income (loss) per ordinary share is computed by dividing net income (loss) by the weighted average number of ordinary shares outstanding for the period. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value. The calculation of diluted income (loss) per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 16,213,430 Class A ordinary shares in the aggregate. As of December 31, 2021 and 2020, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the periods presented. The following table reflects the calculation of basic and diluted net income (loss) per ordinary share (in dollars, except per share amounts): ​ ​ Year Ended December 31, 2021 ​ ​ For the Period from August 20, 2020 (Inception) Through December 31, 2020 ​ ​ Class A ​ ​ Class B ​ ​ Class A ​ ​ Class B Basic and diluted net income (loss) per ordinary share ​ ​ ​ ​ ​ ​ ​ ​ Numerator: ​ ​ ​ ​ ​ ​ ​ ​ Allocation of net income (loss), as adjusted ​ ​ $ 4,478,469 ​ ​ $ 1,119,617 ​ ​ $(4,486,647) ​ ​ $(3,312,113) Denominator: ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted average shares outstanding ​ ​ 17,250,000 ​ ​ 4,312,500 ​ ​ 5,303,571 ​ ​ 3,915,179 Basic and diluted net income (loss) per ordinary share ​ ​ $ 0.26 ​ ​ $ 0.26 ​ ​ $ (0.85) ​ ​ $ (0.85) Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the Company’s balance sheet, primarily due to their short-term nature, other than warrant liabilities (see note 8). Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. Warrant Liability The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The Company accounts for the Warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment. Recent Accounting Standards In August 2020, the FASB issued ASU No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2020-06 effective as of January 1, 2021. The adoption of ASU 2020-06 did not have an impact on the Company’s consolidated financial statements. Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

RELATED PARTY TRANSACTIONS [Abstract]
RELATED PARTY TRANSACTIONS	NOTE 5 — RELATED PARTY TRANSACTIONS Founder Shares On August 28, 2020, the Sponsor paid $25,000 to cover certain offering and formation costs of the Company in consideration for 5,750,000 Class B ordinary shares (the “Founder Shares”). On November 13, 2020, the Sponsor effected a surrender of 1,437,500 Founder Shares to the Company for no consideration, resulting in a decrease in the total number of Class B ordinary shares outstanding to 4,312,500 shares. The Founder Shares included an aggregate of up to 562,500 shares that were subject to forfeiture depending on the extent to which the underwriter’s over-allotment option was exercised, so that the number of Founder Shares would equal, on an as-converted basis, approximately 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. As a result of the underwriter’s election to fully exercise their over-allotment option on November 25, 2020, no Founder Shares are currently subject to forfeiture. The Sponsor has agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earliest of: (A) one year after the completion of the Business Combination or a proposed alternative business combination and (B) subsequent to the Business Combination or a proposed alternative business combination, (x) if the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination or a proposed alternative business combination, or (y) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Public Shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property. Administrative Support Agreement Commencing on November 18, 2020, the Company entered into an agreement to pay the Sponsor up to $10,000 per month for office space, utilities, secretarial and administrative support services. Upon completion of the Business Combination or a proposed alternative business combination or its liquidation, the Company will cease paying these monthly fees. For each of the three months ended March 31, 2022 and 2021, the Company incurred and paid $30,000 in fees for these services. Related Party Loans In order to finance transaction costs in connection with the Business Combination or a proposed alternative business combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes the Business Combination or a proposed alternative business combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that the Business Combination or a proposed alternative business combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of the Business Combination or a proposed alternative business combination, without interest, or, at the lender’s discretion, up to $1,500,000 of such Working Capital Loans may be convertible into warrants of the post-Business Combination or proposed alternative business combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. As of March 31, 2022 and December 31, 2021, the Company had no outstanding borrowings under the Working Capital Loans.

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 6 — COMMITMENTS AND CONTINGENCIES Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 global pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, its results of operations and/or search for a target company, the specific impact is not readily determinable as of the date of these condensed consolidated financial statements. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Registration and Shareholders Rights Pursuant to a registration and shareholders rights agreement entered into on November 23, 2020, the holders of the Founder Shares, Private Placement Warrants and any warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans) will have registration rights to require the Company to register a sale of any of securities held by them. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to completion of the Business Combination or a proposed alternative business combination. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The underwriter is entitled to a deferred fee of $0.35 per Unit, or $6,037,500 in the aggregate. The deferred fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that the Company completes the Business Combination or a proposed alternative business combination, subject to the terms of the underwriting agreement. Business Combination Agreement On December 17, 2021, L&F Acquisition Corp., a Cayman Islands exempted company (“LNFA”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among LNFA, L&F Acquisition Holdings, LLC, a Delaware limited liability company (“L&F Holdings”), ZF Merger Sub, Inc., a Delaware corporation (“ZF Merger Sub”), IDX Merger Sub, Inc., a Delaware corporation (“IDX Merger Sub”), IDX Forward Merger Sub, LLC, a Delaware limited liability company (“IDX Forward Merger Sub”), ZeroFox, Inc., a Delaware corporation (“ZeroFox”), and ID Experts Holdings, Inc., a Delaware corporation (“IDX”).

The Company entered into an agreement with Stifel, Nicolaus & Company, Incorporated (“Stifel”).

Pursuant to the Common Equity Subscription Agreements, the investors agreed to subscribe for and purchase, and LNFA agreed to issue and sell to such investors, on the Closing Date (as defined in the Business Combination Agreement), an aggregate of 2,000,000 shares of LNFA Common Stock in exchange for an aggregate purchase price of $20,000,000 (the “Common Equity PIPE Financing”). In addition, on December 16, 2021, the ZF Investors purchased PIK promissory notes issued by ZeroFox (the “ZF PIK Promissory Notes”) for an aggregate purchase price of $5,000,000. Such ZF PIK Promissory Notes accrue interest that will be paid-in-kind at a rate of 5.0% per annum. If the Closing occurs, the repayment of the original principal amount of the ZF PIK Promissory Notes may be offset against amounts owed by the ZF investors under their Common Equity Subscription Agreements. In addition, if the Closing occurs, any portion of closing cash consideration to which the IDX Investors are entitled in connection with the consummation of the Business Combination may be reduced to fund the subscription amount the IDX Investors would otherwise be required to pay pursuant to the Common Equity Subscription Agreements. The closing of the Common Equity PIPE Financing is contingent upon, among other things, the substantially concurrent consummation of the Business Combination. The Common Equity Subscription Agreements provide that LNFA will grant the investors in the Common Equity PIPE Financing certain customary registration rights. Convertible Notes Investment In connection with signing the Business Combination Agreement, LNFA entered into convertible note subscription agreements (the “Convertible Note Subscription Agreements”) with affiliates of Monarch Alternative Capital LP, Victory Park Capital and Corbin Capital (the “Note Investors”), in respect of $150,000,000 aggregate principal amount of unsecured convertible notes due in 2025 (the “Notes”) to be issued in connection with the closing of the Business Combination (the “Convertible Notes Financing”). The principal terms of the Notes are set forth in the form of indenture attached as an exhibit to the Convertible Note Subscription Agreements, which indenture shall be entered into by LNFA, the guarantors party thereto and the indenture trustee (the “Indenture”), and the form of global note attached thereto. The Notes will bear interest at a rate of 7.00% per annum, payable quarterly in cash; provided, that the issuer may elect to pay interest in kind at 8.75% per annum, and the Notes will be convertible at an initial conversion price of $11.50, subject to customary anti-dilution adjustments, including with respect to stock-splits and stock dividends, dividends and other distributions, above-market tender offers, below-market rights offerings and spin-offs (the “Conversion Price”), and shall mature on the date that is three years following the closing of the Convertible Notes Financing. The post-Business Combination company may, at its election, force conversion of the Notes after the first anniversary of the issuance of the Notes (the “Conversion Trigger Date”), subject to a holder’s prior right to convert, if the volume-weighted average trading price of the post-Business Combination company’s common stock (x) for the first year after the Conversion Trigger Date, is greater than or equal to 150% of the conversion price for more than 20 trading days during a period of 30 consecutive trading days and (y) for the second year after the Conversion Trigger Date, is greater than or equal to 130% of the conversion price for more than 20 trading days during a period of 30 consecutive trading days. Each holder of a Note will have the right to cause the post-Business Combination company to repurchase for cash all or a portion of the Notes held by such holder at any time upon the occurrence of a “fundamental change”, a customary definition provided in the Indenture (a “Fundamental Change”), at a price equal to par plus accrued and unpaid interest. In the event of a conversion in connection with a Fundamental Change, the Conversion Price will be adjusted by a usual and customary Fundamental Change “make-whole table” to be agreed in the Indenture. The Indenture will include restrictive covenants that, among other things, will limit the ability of the post-Business Combination company to incur senior debt in excess of $50,000,000, subject to certain qualifications and exceptions set forth in the Indenture. The Indenture also will include customary events of default. The closing of the Convertible Notes Financing is contingent upon, among other things, the substantially concurrent consummation of the Business Combination. LNFA has agreed to execute a registration rights agreement for the benefit of the Note Investors, providing for customary demand, shelf and piggyback registration rights and otherwise in form and substance acceptable to the Note Investors and LNFA.	NOTE 6 — COMMITMENTS AND CONTINGENCIES Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 global pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, its results of operations and/or search for a target company, the specific impact is not readily determinable as of the date of these consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Registration and Shareholders Rights Pursuant to a registration and shareholders rights agreement entered into on November 23, 2020, the holders of the Founder Shares, Private Placement Warrants and any warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans) will have registration rights to require the Company to register a sale of any of securities held by them. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to completion of a Business Combination. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The underwriter is entitled to a deferred fee of $0.35 per Unit, or $6,037,500 in the aggregate. The deferred fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

WARRANTS (FY)

WARRANTS (FY)	3 Months Ended	12 Months Ended
	Mar. 31, 2022	Dec. 31, 2021
WARRANTS [Abstract]
WARRANTS	NOTE 8 — WARRANTS At March 31, 2022 and December 31, 2021, there were 8,625,000 Public Warrants and 7,588,430 Private Placement Warrants, respectively outstanding. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of the Business Combination or a proposed alternative business combination and (b) one year from the closing of the Initial Public Offering. The Public Warrants will expire five years from the completion of the Business Combination or a proposed alternative business combination or earlier upon redemption or liquidation. The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary share issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. The Company has agreed that as soon as practicable, but in no event later than 20 business days, after the closing of the Business Combination or a proposed alternative business combination it will use its best efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants. The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement and a current prospectus relating thereto until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the sixtieth (60th) business day after the closing of the Business Combination or a proposed alternative business combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.01 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; and • if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders. If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.10 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined based on the redemption date and the fair market value of the Class A ordinary shares; • if, and only if, the closing price of the Class A ordinary shares equal or exceeds $10.00 per public share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company send the notice of redemption of the warrant holders; and • if the closing price of the Class A ordinary shares for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants. If the Company calls the Public Warrants for redemption, as described above, its management will have the option to require any holder that wishes to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of ordinary shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for issuances of ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the Public Warrants. If the Company is unable to complete the Business Combination or a proposed alternative business combination within the Extended Combination Period and the Company liquidates the funds held in the Trust Account, holders of Public Warrants will not receive any of such funds with respect to their Public Warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such Public Warrants. Accordingly, the Public Warrants may expire worthless. In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the Business Combination or a proposed alternative business combination at an issue price or effective issue price of less than $9.20 per Class A ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the Business Combination or a proposed alternative business combination on the date of the consummation of the Business Combination or a proposed alternative business combination (net of redemptions), and (z) the volume weighted average trading price of the Class A ordinary shares during the 10 trading day period starting on the trading day prior to the day on which the Company consummates the Business Combination or a proposed alternative business combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price. The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of the Business Combination or a proposed alternative business combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable, except as described above, so long as they are held by the initial purchasers, Jefferies LLC or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers, Jefferies LLC or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. Further, in accordance with FINRA Rule 5110(g)(8)(A), the Private Placement Warrants purchased by Jefferies LLC will not be exercisable for more than five years from the effective date of the registration statement filed in connection with the Company’s Initial Public Offering for so long as they are held by the Jefferies LLC.	NOTE 8 —WARRANTS At December 31, 2021 and 2020, there were 8,625,000 Public Warrants and 7,588,430 Private Placement Warrants, respectively outstanding. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination and (b) one year from the closing of the Initial Public Offering. The Public Warrants will expire five years from the completion of a Business Combination or earlier upon redemption or liquidation. The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary share issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. The Company has agreed that as soon as practicable, but in no event later than 20 business days, after the closing of a Business Combination, it will use its best efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants. The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement and a current prospectus relating thereto until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the sixtieth (60th) business day after the closing of a Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.01 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; and • if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders. If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.10 per warrant; • upon a minimum of 30 days’ prior written notice of redemption; provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined based on the redemption date and the fair market value of the Class A ordinary shares; • if, and only if, the closing price of the Class A ordinary shares equal or exceeds $10.00 per public share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company send the notice of redemption of the warrant holders; and • if the closing price of the Class A ordinary shares for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants. If the Company calls the Public Warrants for redemption, as described above, its management will have the option to require any holder that wishes to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of ordinary shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for issuances of ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the Public Warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of Public Warrants will not receive any of such funds with respect to their Public Warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such Public Warrants. Accordingly, the Public Warrants may expire worthless. In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at an issue price or effective issue price of less than $9.20 per Class A ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of a Business Combination on the date of the consummation of a Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Class A ordinary shares during the 10 trading day period starting on the trading day prior to the day on which the Company consummates a Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price. The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable, except as described above, so long as they are held by the initial purchasers, Jefferies LLC or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers, Jefferies LLC or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. Further, in accordance with FINRA Rule 5110(g)(8)(A), the Private Placement Warrants purchased by Jefferies LLC will not be exercisable for more than five years from the effective date of the registration statement filed in connection with the Company’s Initial Public Offering for so long as they are held by the Jefferies LLC.

FAIR VALUE MEASUREMENTS [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 9 — FAIR VALUE MEASUREMENTS The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability. At March 31, 2022 and December 31, 2021, assets held in the Trust Account were comprised of $175,126,678 and $175,110,029, respectively in a money market fund which is invested in U.S. Treasury Securities. During March 31, 2022 and December 31, 2021, the Company did not withdraw any interest income from the Trust Account. The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at March 31, 2022 and December 31, 2021 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value.

The estimated fair value of the Public Warrants transferred from a Level 3 measurement to a Level 1 fair value measurement during the year ended December 31, 2021 was $6,028,013.

The Modified Black Scholes model’s primary unobservable input utilized in determining the fair value of the Private Warrants is the expected volatility of the ordinary shares. The expected volatility as of the Initial Public Offering date was derived from observable public warrant pricing on comparable ‘blank-check’ companies without an identified target. The expected volatility as of subsequent valuation dates was implied from the Company’s own public warrant pricing. A Monte Carlo simulation methodology was used in estimating the fair value of the Public Warrants as of November 23, 2020 and December 31, 2020, for periods where no observable traded price was available, using the same expected volatility as was used in measuring the fair value of the Private Warrants. For periods subsequent to the detachment of the Public Warrants from the Units, the close price of the Public Warrant price was used as the fair value as of each relevant date. The key inputs into the Black-Scholes-Merton model for the Private Placement Warrants were as follows: Input ​ ​ March 31, 2022 ​ ​ December 31, 2021 Risk-free interest rate ​ ​ 2.42% ​ ​ 1.26% Trading days per year ​ ​ 252 ​ ​ 252 Volatility ​ ​ 11.0% ​ ​ 22.0% Exercise price ​ ​ $ 11.50 ​ ​ $11.50 Stock Price ​ ​ $10.12 ​ ​ $10.03	NOTE 9 — FAIR VALUE MEASUREMENTS The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed consolidated or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the period presented. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K, as filed with the SEC on March 14, 2022. The interim results for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the period ending December 31, 2022 or for any future periods.	Basis of Presentation The accompanying consolidated financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”).

All significant intercompany balances and transactions have been eliminated in consolidation.	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of March 31, 2022 and December 31, 2021.

Marketable Investments Held in Trust Account	Marketable Investments Held in Trust Account At March 31, 2022 and December 31, 2021, substantially all of the assets held in the Trust Account were held in a money market fund that only holds U.S. Treasury Securities.	Marketable Investments Held in Trust Account At December 31, 2021 and 2020, substantially all of the assets held in the Trust Account were held in a money market fund that only holds U.S. Treasury Securities.
Offering Costs	Offering Costs Offering costs consisted of legal, accounting and other expenses incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities were expensed as incurred in the condensed consolidated statements of operations. Offering costs associated with the Class A ordinary share issued were initially charged to temporary equity and then accreted to ordinary shares subject to redemption upon the completion of the Initial Public Offering. Offering costs amounting to $9,243,241 were charged to shareholders’ equity and offering costs amounting to $807,424 were charged to the statement of operations upon the completion of the Initial Public Offering (see Note 1).

Offering costs amounting to $9,243,241 were charged to stockholders’ equity and offering costs amounting to $807,424 were charged to the statement of operations upon the completion of the Initial Public Offering (see Note 1).
Class A Ordinary Shares Subject to Possible Redemption	Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption are classified as a liability instrument and are measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March 31, 2022 and December 31, 2021, Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s condensed consolidated balance sheets. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable Class A ordinary shares resulted in charges against additional paid-in capital and accumulated deficit. At March 31, 2022 and December 31, 2021, the Class A ordinary shares reflected in the condensed Gross proceeds ​ ​ $175,087,500 Less: ​ ​ Proceeds allocated to Public Warrants ​ ​ (13,196,250) Class A ordinary shares issuance costs ​ ​ (9,243,241) Excess funds in trust from sale of Private Warrants ​ ​ (2,587,500) Plus: ​ ​ Accretion of carrying value to redemption value ​ ​ 25,026,991 Class A ordinary shares subject to possible redemption ​ ​ $175,087,500
Income Taxes	Income Taxes The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2022 and December 31, 2021, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

As of December 31, 2021 and 2020, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.
Net Income Per Ordinary Share	Net Income Per Ordinary Share The Company complies with accounting and disclosure requirements of the Financial Accounting Standards Board (“FASB”) ASC Topic 260, “Earnings Per Share”. Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value. The calculation of diluted income per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 16,213,430 Class A ordinary shares in the aggregate. As of March 31, 2022 and 2021, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the periods presented. The following table reflects the calculation of basic and diluted net income per ordinary share (in dollars, except per share amounts): ​ ​ For the Three Months Ended March 31, ​ ​ 2022 ​ ​ 2021 ​ ​ Class A ​ ​ Class B ​ ​ Class A ​ ​ Class B Basic and diluted net income per ordinary share ​ ​ ​ ​ ​ ​ ​ ​ Numerator: ​ ​ ​ ​ ​ ​ ​ ​ Allocation of net income, as adjusted ​ ​ $ 5,582,412 ​ ​ $1,395,603 ​ ​ $ 8,469,074 ​ ​ $ 2,117,268 Denominator: ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted average shares outstanding ​ ​ 17,250,000 ​ ​ 4,312,500 ​ ​ 17,250,000 ​ ​ 4,312,500 Basic and diluted net income per ordinary share ​ ​ $ 0.32 ​ ​ $ 0.32 ​ ​ $ 0.49 ​ ​ $ 0.49	Net Loss Per Ordinary Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share”.

Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the Company’s condensed consolidated balance sheet, primarily due to their short-term nature, other than warrant liabilities (see Note 9).

Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Warrant Liabilities	Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The Company accounts for the Warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in the FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment.

Recent Accounting Standards	Recent Accounting Standards Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.	Recent Accounting Standards In August 2020, the FASB issued ASU No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2020-06 effective as of January 1, 2021. The adoption of ASU 2020-06 did not have an impact on the Company’s consolidated financial statements. Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed consolidated or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the period presented. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K, as filed with the SEC on March 14, 2022. The interim results for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the period ending December 31, 2022 or for any future periods.	Basis of Presentation The accompanying consolidated financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”).
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of March 31, 2022 and December 31, 2021.

Marketable Investments Held in Trust Account	Marketable Investments Held in Trust Account At March 31, 2022 and December 31, 2021, substantially all of the assets held in the Trust Account were held in a money market fund that only holds U.S. Treasury Securities.	Marketable Investments Held in Trust Account At December 31, 2021 and 2020, substantially all of the assets held in the Trust Account were held in a money market fund that only holds U.S. Treasury Securities.
Offering Costs	Offering Costs Offering costs consisted of legal, accounting and other expenses incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities were expensed as incurred in the condensed consolidated statements of operations. Offering costs associated with the Class A ordinary share issued were initially charged to temporary equity and then accreted to ordinary shares subject to redemption upon the completion of the Initial Public Offering. Offering costs amounting to $9,243,241 were charged to shareholders’ equity and offering costs amounting to $807,424 were charged to the statement of operations upon the completion of the Initial Public Offering (see Note 1).

Class A Ordinary Shares Subject to Possible Redemption		Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption are classified as a liability instrument and are measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at December 31, 2021 and 2020, Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheets. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable Class A ordinary shares resulted in charges against additional paid-in capital and accumulated deficit. At December 31, 2021, the Class A ordinary shares reflected in the balance sheets are reconciled in the following table: Gross proceeds ​ ​ $175,087,500 Less: ​ ​ Proceeds allocated to Public Warrants ​ ​ (13,196,250) Class A ordinary shares issuance costs ​ ​ (9,243,241) Excess funds in trust from sale of Private Warrants ​ ​ (2,587,500) Plus: ​ ​ Accretion of carrying value to redemption value ​ ​ 25,026,991 Class A ordinary shares subject to possible redemption ​ ​ $175,087,500
Income Taxes	Income Taxes The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2022 and December 31, 2021, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Net Loss Per Ordinary Share	Net Income Per Ordinary Share The Company complies with accounting and disclosure requirements of the Financial Accounting Standards Board (“FASB”) ASC Topic 260, “Earnings Per Share”. Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value. The calculation of diluted income per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 16,213,430 Class A ordinary shares in the aggregate. As of March 31, 2022 and 2021, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the periods presented. The following table reflects the calculation of basic and diluted net income per ordinary share (in dollars, except per share amounts): ​ ​ For the Three Months Ended March 31, ​ ​ 2022 ​ ​ 2021 ​ ​ Class A ​ ​ Class B ​ ​ Class A ​ ​ Class B Basic and diluted net income per ordinary share ​ ​ ​ ​ ​ ​ ​ ​ Numerator: ​ ​ ​ ​ ​ ​ ​ ​ Allocation of net income, as adjusted ​ ​ $ 5,582,412 ​ ​ $1,395,603 ​ ​ $ 8,469,074 ​ ​ $ 2,117,268 Denominator: ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted average shares outstanding ​ ​ 17,250,000 ​ ​ 4,312,500 ​ ​ 17,250,000 ​ ​ 4,312,500 Basic and diluted net income per ordinary share ​ ​ $ 0.32 ​ ​ $ 0.32 ​ ​ $ 0.49 ​ ​ $ 0.49	Net Loss Per Ordinary Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share”.

Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Warrant Liability	Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The Company accounts for the Warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in the FASB Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment.	Warrant Liability The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The Company accounts for the Warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment. The Company assessed both Public and Private Warrants and determined both met the criteria for liability treatment.
Recent Accounting Standards	Recent Accounting Standards Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.	Recent Accounting Standards In August 2020, the FASB issued ASU No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2020-06 effective as of January 1, 2021. The adoption of ASU 2020-06 did not have an impact on the Company’s consolidated financial statements. Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial statements.
