Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description Of Organization And Business Operations	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Cartesian Growth Corporation (now known as Alvarium Tiedemann Holdings, Inc.) (the “Company”) was incorporated as a Cayman Islands exempted company on December 18, 2020. The Company was incorporated for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or engaging in any other similar business combination with one or more businesses (the “Business Combination”). As of December 31, 2022, the Company had not commenced any operations. All activity through December 31, 2022 relates to the Company’s formation and its initial public offering (the “IPO”) which is described below and 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 generates non-operating income in the form of interest income from the proceeds derived from the IPO. The Company’s sponsor is CGC Sponsor LLC, a Cayman Islands limited liability Company (the “Sponsor”). On February 26, 2021, the Company consummated the IPO, including the full exercise of the over-allotment option by the underwriters on February 23, 2021, of 34,500,000 units (the “Units” and, with respect to the Class A ordinary shares and warrants included in the Units, the “Class A ordinary shares” and “Public Warrants,” respectively), at $10.00 per Unit, generating gross proceeds of $345,000,000, which is further discussed in Note 3. Each Unit consists of one Class A ordinary share and one-third of one redeemable warrant to purchase one Class A ordinary share at a price of $11.50 per whole share. The registration statements on Form S-1 (File Nos. 333-252784 and 333-253428) for the Company’s IPO were declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on February 23, 2021. Simultaneously with the closing of the IPO, the Company consummated the sale of 8,900,000 warrants (the “Private Warrants,” and together with the “Public Warrants,” the “Warrants”), at a price of $1.00 per Private Warrant, in a private placement to the Sponsor, generating gross proceeds of $8,900,000, which is further discussed in Note 4. Transaction costs of the IPO amounted to $19,540,060, consisting of $6,900,000 of underwriting commission, $12,075,000 of deferred underwriting commission, and $565,060 of other offering costs. Following the closing of the IPO on February 26, 2021, $345,000,000 (or $10.00 per Unit) of the net offering proceeds of the sale of the Units and the sale of the Private Warrants was placed in a trust account for the benefit of the Company’s public shareholders (the “Trust Account”), with Continental Stock Transfer & Trust Company acting as trustee. The proceeds in the Trust Account may be invested in U.S. government treasury bills with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act that invest only in direct U.S. government treasury obligations. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay its taxes, if any, the funds held in the Trust Account will not be released from the Trust Account until the earliest to occur of: (i) the completion of an initial Business Combination, (ii) the redemption of the Class A ordinary shares if the Company is unable to complete its initial Business Combination by February 26, 2023, subject to applicable law, and (iii) the redemption of any Class A ordinary shares properly tendered in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association (a) to modify the substance or timing of the Company’s obligation to redeem 100% of the Class A ordinary shares if it does not complete its initial Business Combination by February 26, 2023 or (b) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity. The Company will provide the holders of its outstanding Class A ordinary shares (the “public shareholders”) with the opportunity to redeem all or a portion of their Class A ordinary shares upon the completion of the initial 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, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require the Company to seek shareholder approval under the law or stock exchange listing requirement. The public shareholders will be entitled to redeem their shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the initial Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, if any, divided by the number of then outstanding Class A ordinary shares. The amount in the Trust Account is initially anticipated to be $ per public share. The per share amount the Company will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters. The Company will have until February 26, 2023 to complete the initial Business Combination. If the Company is unable to complete the initial Business Combination by February 26, 2023, 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 business days thereafter, redeem 100% of the Class A ordinary shares, 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 funds held in the Trust Account (less tax payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Class A ordinary shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii) to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. The Company’s initial shareholders, officers and directors have agreed to (i) waive their redemption rights with respect to their Class B ordinary shares, par value of $0.0001 per share (the “founder shares”) (as described in Note 3) and any Class A ordinary shares purchased during or after the IPO, in connection with the completion of the initial Business Combination, (ii) waive their rights to liquidating distributions from the Trust Account with respect to their founder shares if the Company fails to complete the initial Business Combination by February 26, 2023, although they will be entitled to liquidating distributions from the Trust Account with respect to any Class A ordinary shares they acquired during or after the IPO if the Company fails to complete the initial Business Combination within the prescribed time frame, and (iii) vote any founder shares held by them and any Class A ordinary shares purchased during or after the IPO (including in open market and privately-negotiated transactions) in favor of the initial Business Combination. The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party 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. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, then the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company has not independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company has not asked the Sponsor to reserve for such indemnification obligations. Therefore, the Company cannot assure you that the Sponsor would be able to satisfy those obligations. As a result, if any such claims were successfully made against the Trust Account, the funds available for the initial Business Combination and redemptions could be reduced to less than $10.00 per public share. In such event, the Company may not be able to complete the initial Business Combination, and the public shareholders would receive such lesser amount per share in connection with any redemption of the Class A ordinary shares. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses . The Business Combination On September 19, 2021, the Company, Tiedemann Wealth Management Holdings, LLC, a Delaware limited liability company (“TWMH”), TIG Trinity GP, LLC, a Delaware limited liability company (“TIG GP”), TIG Trinity Management, LLC, a Delaware limited liability company (“TIG MGMT” and, together with TIG GP, the “TIG Entities”), Alvarium Investments Limited, an English private limited company (“Alvarium” and, together with TWMH and the TIG Entities, the “Target Companies”), Rook MS LLC, a Delaware limited liability company and Alvarium Tiedemann Capital, LLC, a Delaware limited liability company (“Umbrella”) entered into a business combination agreement (as may be amended, supplemented, or otherwise modified from time to time, the “Business Combination Agreement”), pursuant to which the Company will hold Umbrella, a newly formed Delaware limited liability company for purposes of effecting the transactions contemplated by the Business Combination Agreement, which will hold the businesses of the Target Companies.

The transaction is expected to close materially before our mandatory liquidation date. The Company filed amendments to the Form S-4 with the SEC on May 13, 2022, June 27, 2022, July 25, 2022 and August 8, 2022. On October 17, 2022, the SEC declared effective the Form S-4 and the Company commenced mailing the definitive proxy statement/prospectus relating to the Company’s extraordinary general meeting to be held on November 17, 2022 in connection with the Business Combination. Subscription Agreements Concurrently with the execution of the Business Combination Agreement, we entered into subscription agreements (the “PIPE Subscription Agreements”) with certain investors (each a “PIPE Investor”) to purchase, following the Domestication, Class A Common Stock (such shares, collectively, “PIPE Shares”) in an aggregate value of $164,999,807, representing 16,936,715 PIPE Shares at a price of $9.80 per share. The closing of the sale of PIPE Shares (the “PIPE Closing”) will occur immediately prior to the Closing. The PIPE Closing will be subject to customary conditions, including, but not limited to: i. all representations and warranties of us and the PIPE Investor contained in the relevant PIPE Subscription Agreement will be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Material Adverse Effect (as defined in the PIPE Subscription Agreements), which representations and warranties will be true in all respects) at, and as of, the PIPE Closing; ii. all conditions precedent to the Closing will have been satisfied or waived; and iii. without the consent of the PIPE Investor, the Business Combination Agreement cannot be amended, modified or waived in a manner that reasonably would be expected to materially and adversely affect the economic benefits the PIPE Investor reasonably would expect to receive under the PIPE Subscription Agreement. Pursuant to the PIPE Subscription Agreements, we agreed that, within 45 calendar days after the consummation of the Proposed Business Combination, we will file with the SEC a registration statement registering the resale of the PIPE Shares, and we will use our commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing thereof; provided, however, that our obligations to include the shares held by a PIPE Investor in such registration statement will be contingent upon the respective PIPE Investor furnishing in writing to us such information regarding the PIPE Investor, the securities held by such PIPE Investor and the intended method of disposition of the shares, as will be reasonably requested by us to effect the registration of such shares, and will execute such documents in connection with such registration, as us may reasonably request that are customary of a selling shareholder in similar situations. Each PIPE Subscription Agreement will terminate upon the earlier to occur of (i) such date and time as the Business Combination Agreement is terminated in accordance with its terms, (ii) upon the mutual written agreement of each of the parties to the PIPE Subscription Agreement; or (iii) if any of the conditions to PIPE Closing set forth in Sections 3.2 and 3.3 of such PIPE Subscription Agreement are not satisfied on or prior to the Closing Date and, as a result thereof, the transactions contemplated by such PIPE Subscription Agreement are not consummated at the PIPE Closing. On October 25, 2022, we amended each of the PIPE Subscription Agreements, solely to redefine “Subscribed Shares” in the PIPE Subscription Agreements to refer to the sum of the Base Share Number (as defined therein) plus a number of Shares (as defined in the Sponsor Support Agreement dated September 19, 2021 (the “Original Sponsor Support Agreement”)) forfeited pursuant to Section 3 of the Original Sponsor Support Agreement, multiplied by (b) a fraction (i) the numerator of which is the Base Share Number and (ii) the denominator of which is the sum of the number of the Non-Redeemed SPAC Class A Common Shares and the number of Private Placement Shares (each as defined therein). Registration Statement on Form S-4 The Company filed a registration statement on Form S-4 (File No. 333-262644) (the “Form S-4”) with the SEC on February 11, 2022, in connection with the Business Combination Agreement. The consummation of the transactions contemplated by the Business Combination Agreement is subject to customary conditions, representations and warranties, covenants and closing conditions in the Business Combination Agreement, including, but not limited to, approval by the Company’s shareholders of the Business Combination Agreement, the effectiveness of the Form S-4, and other customary closing conditions, including the receipt of certain regulatory approvals. The transaction is expected to close materially before the Company’s mandatory liquidation date. The Company filed amendments to the Form S-4with the SEC on May 13, 2022, June 27, 2022, July 25, 2022 and August 8, 2022. On October 17, 2022, the SEC declared effective the Form S-4 and the Company commenced mailing the definitive proxy statement/prospectus relating to the Company’s extraordinary general meeting to be held on November 17, 2022 in connection with the Business Combination.

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 stockholder 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 statements 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 the financial statements in conformity with U.S. GAAP requires 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 expenses during the reporting periods. 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. One of the more significant accounting estimates included in these financial statements is the determination of the fair value of the warrant liabilities. Such estimates may be subject to change as more current information becomes available and 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 had cash of $85,540 and $551,258 as of December 31, 2022 and 2021, respectively. The Company did not have any cash equivalents as of December 31, 2022 and 2021. 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 Deposit Insurance Corporation coverage. The Company has not experienced losses on this account. Cash and Marketable Securities Held in Trust Account Through December 29, 2022 and at December 31, 2021, substantially all of the assets held in the Trust Account were held in money market funds which invest in U.S. Treasury securities. At December 31, 2022, substantially all of the assets held in the Trust account were transferred and held in the cash in preparation for the Business Combination closing date. Convertible Debt The Company accounts for promissory note that feature conversion options in accordance with Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 815, “Derivatives and Hedging” (“ASC 815”). ASC 815 requires companies to bifurcate conversion options from their host instruments and account for them as freestanding derivative financial instruments according to certain criteria. These criteria include circumstances in which (i) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (ii) a promissory note that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable GAAP with changes in fair value reported in earnings as they occur and (iii) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument. Warrant Liabilities The Company evaluates the Warrants (which are discussed in Note 3, Note 4 and Note 9), in accordance with FASB ASC Topic 815-40, “Derivatives and Hedging, Contracts in Entity’s Own Equity” (“ASC 815-40”) and concluded that a provision in its warrant agreement related to certain tender or exchange offers precludes the Warrants from being accounted for as components of equity. As the Warrants meet the definition of a derivative as contemplated in ASC 815-40, the Warrants are recorded as derivative liabilities on the balance sheets and measured at fair value at inception (the date of the IPO) and at each reporting date in accordance with FASB ASC Topic 820, “Fair Value Measurement,” with changes in fair value recognized in the statements of operations in the period of change Offering Costs Associated with the Initial Public Offering The Company complies with the requirements of the FASBASC 340-10-S99-1. Offering costs consisted of legal fees, accounting fees, underwriting fees and other costs incurred through the IPO that were directly related to the IPO. Offering costs are allocated to the separable financial instruments issued in the IPO based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred, presented as non-operating expenses in the statements of operations. Offering costs associated with the Class A ordinary shares were charged to temporary equity upon the completion of the IPO. 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 ASC Topic 480 “Distinguishing Liabilities from Equity” (ASC 480). Ordinary shares subject to mandatory redemption (if any) are classified as a liability instrument and 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. All of the 34,500,000 Class A ordinary shares contain a redemption feature which allows for the redemption of such Class A ordinary shares in connection with the Company’s liquidation, if there is a shareholder vote or tender offer in connection with the Business Combination and in connection with certain amendments to the Company’s amended and restated memorandum and articles of association. In accordance with the SEC and its staff’s guidance on redeemable equity instruments, which has been codified in ASC 480-10-S99, redemption provisions not solely within the control of the Company require ordinary shares subject to redemption to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of ASC 480. Accordingly, at December 31, 2022 and 2021, all Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit 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. Increases or decreases in the carrying amount of redeemable ordinary shares are affected by charges against additional paid in capital and accumulated deficit. As of December 31, 2022 and 2021, the Class A ordinary shares subject to redemption reflected on the balance sheets are reconciled in the following table: Gross Proceeds $ 345,000,000 Less: Proceeds allocated to Public Warrants (15,007,500 ) Class A ordinary shares issuance costs (18,671,929 ) Plus: Remeasurement of carrying value to redemption value 33,679,429 Interest earned on Trust Account 31,308 Class A ordinary shares subject to possible redemption at December 31, 2021 $ 345,031,308 Interest earned on Trust Account 4,952,531 Class A ordinary shares subject to possible redemption at December 31, 2022 $ 349,983,839 Income Taxes The Company accounts for income taxes under ASC 740, “Income Taxes” (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position 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 recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2022 and 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. There is currently no taxation imposed on income by the government of the Cayman Islands. In accordance with Cayman Islands income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Fair Value of Financial Instruments The Company follows the guidance in FASB ASC Topic 820, “Fair Value Measurement,” for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually. The fair value of certain 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 –Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Valuation adjustments and block discounts are not being applied. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these securities does not entail a significant degree of judgment. Level 2 –Valuations based on (i) quoted prices in active markets for similar assets and liabilities, (ii) quoted prices in markets that are not active for identical or similar assets, (iii) inputs other than quoted prices for the assets or liabilities, or (iv) inputs that are derived principally from or corroborated by market through correlation or other means. Level 3 –Valuations based on inputs that are unobservable and significant to the overall fair value measurement. See Note 9 for additional information on assets and liabilities measured at fair value. Net Income (Loss) per Share The Company complies with the accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” Net (loss) income per share is computed by dividing net (loss) income by the weighted average number of ordinary shares outstanding during the period. The Company has two classes of shares, Class A ordinary shares and Class B ordinary shares. Earnings and losses are shared pro rata between the two classes of shares. The Company has not considered the effect of the 20,400,000 Class A ordinary shares underlying the 11,500,000 Warrants and the 8,900,000 Private Warrants, in the calculation of diluted net (loss) income per share, since the exercise of the Warrants is contingent upon the occurrence of future events. As a result, diluted net (loss) income per ordinary share is the same as basic net (loss) income per ordinary share for the period presented. The Company’s statements of operations apply the two-class method in calculating net (loss) income per share. Basic and diluted net (loss) income per Class A ordinary share and Class B ordinary share is calculated by dividing net (loss) income attributable to the Company by the weighted average number of Class A ordinary shares and Class B ordinary shares outstanding, allocated proportionally to each class of shares. Reconciliation of Net (Loss) Income per Share The Company’s net (loss) income is adjusted for the portion of net (loss) income that is allocable to each class of shares. The allocable net (loss) income is calculated by multiplying net (loss) income by the ratio of weighted average number of shares outstanding attributable to Class A ordinary shares and Class B ordinary shares to the total weighted average number of shares outstanding for the period. Remeasurement of the carrying value of Class A ordinary shares to redemption value is excluded from net (loss) income per ordinary share because the redemption value approximates fair value. Accordingly, basic and diluted (loss) income per ordinary share is calculated as follows: For the Year Ended For the Year Ended Class A Ordinary Shares Numerator: Net income (loss) allocable to Class A ordinary shares Net income (loss) $ 8,779,014 $ (1,035,380 ) Less: Allocation of net income (loss) to Class B ordinary shares (1,755,803 ) (232,904 ) Proportionate share of net income (loss) $ 7,023,211 $ (802,476 ) Denominator: Weighted Average Class A ordinary shares Basic and diluted weighted average shares outstanding 34,500,000 29,112,329 Basic and diluted net income (loss) per share $ 0.20 $ (0.03 ) Class B Ordinary Shares Numerator: Net income (loss) allocable to Class B ordinary shares Net income (loss) $ 8,779,014 $ (1,035,380 ) Less: Allocation of net income (loss) to Class A ordinary shares (7,023,211 ) (802,476 ) Proportionate share of net income (loss) $ 1, 755,803 $ (232,904 ) Denominator: Weighted Average Class B ordinary shares Basic and diluted weighted average shares outstanding 8,625,000 8,449,315 Basic and diluted net income (loss) per share $ 0.20 $ (0.03 ) Recent Accounting Pronouncements The Company’s management does not believe that any other recently issued, but not effective, accounting standards, if currently adopted, would have a material effect on the accompanying financial statements .

Initial Public Offering [Abstract]
Initial Public Offering	NOTE 3. INITIAL PUBLIC OFFERING Public Units On February 26, 2021, upon the consummation of the IPO, the Company sold 34,500,000 Units, which includes the full exercise by the underwriters of the over-allotment option to purchase an additional 4,500,000 Units, at a purchase price of $ 10.00 per Unit. Each Unit consists of one Class A ordinary share, Public Warrants Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed herein. The Public Warrants will become exercisable on the later of 12 months from the closing of the IPO or 30 days after the completion of its initial Business Combination and will expire five years after the completion of the Company’s initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation. In addition, if (i) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the initial 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 its affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (ii) 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 initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (iii) the volume weighted average trading price of the Company’s Class A ordinary shares during the 20 trading day period starting on the trading day prior to the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, then 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 described adjacent to “Redemption of warrants when the price per ordinary share equals or exceeds $18.00” will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, respectively. The Company has agreed that as soon as practicable, but in no event later than fifteen (15) business days after the closing of the initial Business Combination, it will use its commercially reasonable 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 commercially reasonable 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 or redemption of the Warrants in accordance with the provisions of the warrant agreement. 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 it satisfies 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, it will not be required to file or maintain in effect a registration statement or register or qualify the shares under applicable blue sky laws to the extent an exemption is 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 herein with respect to the Private Warrants): • in whole and not in part; • at a price of $0.01 per Warrant; • upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”) to each Warrant holder; • if, and only if, the last sale price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for share splits, share dividends, reorganizations. and recapitalizations), for any 20 trading days within a 30-trading day period ending on the third business day prior to the notice of redemption to the Warrant holders; and • if, and only if, there is a current registration statement in effect with respect to the Class A ordinary shares underlying the Warrants.

Private Placement	NOTE 4. PRIVATE PLACEMENT Simultaneously with the closing of the IPO, the Sponsor purchased an aggregate of 8,900,000 Private Warrants at a price of $1.00 per Private Warrant, for an aggregate purchase price of $8,900,000, in a private placement. A portion of the proceeds from the sale of the Private Warrants was added to the proceeds from the IPO held in the Trust Account. The Private Warrants are identical to the Public Warrants, except that the Private Warrants, so long as they are held by the Sponsor or its permitted transferees, (i) will not be redeemable by the Company, (ii) may not (including the Class A ordinary shares issuable upon exercise of these Private Warrants), subject to certain limited exceptions, be transferred, assigned or sold by the holders until 30 days after the completion of the Company’s initial Business Combination, (iii) may be exercised by the holders on a cashless basis and (iv) will be entitled to certain registration rights. If the Private Warrants are held by holders other than the Sponsor or its permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by the holders on the same basis as the Public Warrants. The initial shareholders, officers, directors and independent directors have agreed to waive their redemption rights with respect to any Class A ordinary shares they may acquire during or after the IPO, in connection with the completion of the initial Business Combination. If the Company does not complete the initial Business Combination within the applicable time period, the proceeds of the sale of the Private Warrants will be used to fund the redemption of the Class A ordinary shares.

Related Party Transactions [Abstract]
Related Party Transactions	NOTE 5. RELATED PARTY TRANSACTIONS Founder Shares On December 31, 2020, the Company issued an aggregate of 7,187,500 founder shares to the Sponsor for an aggregate purchase price of $25,000, or approximately $0.003 per share, in cash. In February 2021, the Sponsor transferred an aggregate of 75,000 founder shares to its independent directors. On February 23, 2021, the Company effectuated a recapitalization, and as a result, the initial shareholders held 8,625,000 founder shares, including up to 1,125,000 founder shares which were subject to forfeiture by the Sponsor, if the over-allotment option was not exercised by the underwriters in full. As a result of the underwriters’ full exercise of their over-allotment option on February 26, 2021, none of the Class B ordinary shares are subject to forfeiture any longer. The initial shareholders have agreed not to transfer, assign or sell any of the founder shares (except to certain permitted transferees) until the earlier of (i) one year after the date of the completion of the initial Business Combination or earlier if, subsequent to the initial Business Combination, the last reported sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, reorganizations and recapitalizations) for any 20 trading days within any30-tradingday period commencing at least 150 days after the initial Business Combination, or (ii) the Company consummates a subsequent liquidation, merger, capital stock exchange or other similar transaction which results in all of the shareholders having the right to exchange their ordinary shares for cash, securities or other property. Promissory Note On December 31, 2020, the Sponsor issued to the Company an unsecured promissory note to borrow up to $250,000 to be used for a portion of the expenses of the IPO. These loans were non-interest bearing, unsecured and were due at the earlier of September 30, 2021 or the closing of the IPO. As of February 26, 2021, the Company had borrowings of $144,890 under the promissory note, and on February 26, 2021, repaid the $144,890 from the proceeds of the IPO. Working Capital Loans In order to fund working capital deficiencies or finance transaction costs in connection with an initial Business Combination, the Sponsor, the Company’s officers, directors or their affiliates may, but are not obligated to, loan the Company funds from time to time as may be required (the “Working Capital Loans”). If the Company completes the initial Business Combination, the Company will repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. In the event that the initial Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay the Working Capital Loans but no proceeds from the Trust Account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans may be convertible into Private Warrants at a price of $1.00 per warrant at the option of the lender. Such warrants would be identical to the Private Warrants. On May 25, 2022, the Company issued an unsecured promissory note (the “Working Capital Note”) in the principal amount of $500,000 to the Sponsor, which was funded in its entirety by the Sponsor upon execution of the Working Capital Note. The Working Capital Note does not bear interest and the principal balance will be payable on the earlier to occur of (i) the date on which the Company consummates its initial Business Combination and (ii) the date that the winding up of the Company is effective (such earlier date, the “Maturity Date”). In the event the Company consummates its initial Business Combination, the Sponsor has the option, on the Maturity Date, to convert all or any portion of the principal outstanding under the Working Capital Note into that number of warrants (“Working Capital Warrants”) equal to the portion of the principal amount of the Working Capital Note being converted, divided by $1.00, rounded up to the nearest whole number. The terms of the Working Capital Warrants, if any, would be identical to the terms of the Private Warrants, including the transfer restrictions applicable thereto. The Working Capital Note is subject to customary events of default, the occurrence of certain of which automatically triggers the unpaid principal balance of the Working Capital Note and all other sums payable with regard to the Working Capital Note becoming immediately due and payable. The issuance of the Working Capital Note was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended. As of December 31, 2022 and 2021, the Company had $ and $ borrowings under the Working Capital Note, net of debt discount of $ and $ , respectively. On January 3, 2023, the outstanding working capital Note was paid in full (see Note 10). Administrative Services Agreement The Company agreed to pay the Sponsor $10,000 per month for office space, utilities, secretarial support and administrative services. The Company began incurring these fees on February 23, 2021 and will continue to incur these fees monthly until the earlier of the completion of an initial Business Combination and the Company’s liquidation. For the year ended December 31, 2022 and 2021, the Company has paid $120,000 and $100,000 in such fees, respectively.

On February 26, 2021, the underwriter fully exercised its over-allotment option. Upon consummation of the IPO on February 26, 2021, the underwriters were paid a cash underwriting fee of 2.0% of the gross proceeds of the IPO, or $6,900,000 in the aggregate. The underwriters of the IPO are entitled to a deferred underwriting commission of 3.5% of the gross proceeds of the IPO, or $12,075,000 in the aggregate. Subject to the terms of the underwriting agreement, the deferred underwriting commission will be payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes an initial Business Combination, and the deferred underwriting commission will be waived by the underwriters in the event that the Company does a Business Combination. On November 14, 2022, the Company and underwriter executed a deferred underwriting commission modification letter confirming the underwriter’s forfeiture collectively of $4,275,000 of the $12,075,000 of deferred underwriting commission that would otherwise be payable to it at the closing of Business Combination. As a result, the Company recognized $195,857 of other income and $4,079,413 was recorded to additional paid-in capital in relation to the forfeiture of a portion of underwriting fee commission in the accompanying financial statements. As of December 31, 2022 and 2021, the outstanding deferred underwriting fee payable were $7,800,000 and $12,075,000, respectively. On January 3, 2023, the outstanding deferred underwriting fee totaling to $7,800,000 was paid in full (see Note 10). Registration Rights On February 23, 2021, the Company entered into a registration rights agreement with respect to the Founder Shares, the Private Warrants and warrants that may be issued upon conversion of the Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Warrants and warrants that may be issued upon conversion of Working Capital Loans), which requires the Company to register such securities for resale (in the case of the Founder Shares, only after conversion to Class A ordinary shares). Pursuant to such registration rights agreement, the holders of the majority of these securities will be entitled to make up to three demands, excluding short form demands, that we register such securities. In addition, the holders will have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of the Company’s initial Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Financial Advisor Engagements and Resignations On September 19, 2021, the Company engaged BofA Securities, Inc. (“BofA”) as its financial (M&A) advisor in connection with the Business Combination. Pursuant to this engagement, the Company agreed to pay to BofA an advisory fee of $3,000,000, contingent and payable upon the closing of a Business Combination. On May 13, 2022, BofA resigned from its role as financial (M&A) advisor to the Company and waived any fees to which it was entitled pursuant to its engagement, and BofA and the Company mutually terminated the engagement letter entered into in connection therewith. On September 19, 2021, the Company engaged BofA as its capital markets advisor in connection with the Business Combination.

Fair Value Measurements	NOTE 9. FAIR VALUE MEASUREMENTS The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at December 31, 2022 and 2021, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: December 31, Quoted Prices in Significant Other Significant Other (Level 3) Assets: Cash held in Trust Account $ 349,983,839 $ 349,983,839 $ — $ — Liabilities: Public Warrants Liability $ 5,882,250 $ 5,882,250 $ — $ — Private Warrants Liability 4,648,890 — — 4,648,890 $ 10,531,140 $ 5,882,250 $ — $ 4,648,890 December 31, Quoted Prices in Significant Other Significant Other (Level 3) Assets: U.S. Money Market held in Trust Account $ 345,031,308 $ 345,031,308 $ — $ — Liabilities: Public Warrants Liability $ 12,765,000 $ 12,765,000 $ — $ — Private Warrants Liability 10,328,609 — — 10,328,609 $ 23,093,609 $ 12,765,000 $ — $ 10,328,609 The Warrants are accounted for as liabilities in accordance with ASC 815-40 and are presented within warrant liabilities on the balance sheets. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the statements of operations. The Company established the initial fair value of the Public Warrants and Private Warrants on February 26, 2021, the date of the Company’s IPO, using a Monte Carlo simulation model. As of December 31, 2022 and 2021, the fair value for the Private Warrants was estimated using a Monte Carlo simulation model, and the fair value of the Public Warrants by reference to the quoted market price. The Public Warrants and Private Warrants were classified as Level 3 at the initial measurement date, and the Private Warrants were classified as Level 3 as of December 31, 2022 and 2021 due to the use of unobservable inputs. For the period ended December 31, 2021, the Public Warrants were reclassified from a Level 3 to a Level 1 classification due to the use of the observed trading price of the separated Public Warrants. For the year ended December 31, 2022, there were no transfers between Levels 1, 2 or 3. The following table presents the changes Level 3 liabilities for the year ended December 31, 2022: Fair Value at January 1, 2022 $ 10,328,609 Change in fair value (5,679,719 ) Fair Value at December 31, 2022 $ 4,648,890 The following table presents the changes Level 3 liabilities for the year ended December 31, 2021: Fair Value at January 1, 2021 $ — Initial fair value of Public Warrants and Private Warrants 27,004,700 Transfer of Public Warrants to Level 1 (15,007,500 ) Change in fair value (1,668,591 ) Fair Value at December 31, 2021 $ 10,328,609 The key inputs into the Monte Carlo simulation model as of December 31, 2022 and 2021 were as follows: December 31, December 31, Risk-free interest rate 4.70 % 1.30 % Expected term remaining (years) 0.46 5.49 Expected volatility 22.5 % 17.5 % Trading stock price $ 10.91 $ 9.88 The Company utilizes a Monte Carlo simulation model to estimate the fair value of the conversion feature of the Working Capital Note, which is required to be recorded at its initial fair value on the date of issuance and each balance sheet date thereafter. Changes in the estimated fair value of the conversion feature of the Working Capital Note are recognized as non-cash gains or losses in the statements of operations. The key assumptions in the Monte Carlo simulation model relate to the expected trading share-price volatility of the Class A ordinary shares, risk-free interest rate, strike price – warrants and debt conversion, expected term of the warrants and the probability of consummation of a Business Combination. The expected trading share-price volatility of the Class A ordinary shares is based on the average trading share price volatility of shares of special purpose acquisition companies (SPACs) that are searching for a target to consummate a business combination. The risk-free interest rate is based on interpolation of U.S. Treasury yields with a term commensurate with the term of the warrants. The Company anticipates the dividend yield to be zero. The expected term of the warrants is assumed to be the timing and likelihood of consummating a Business Combination. The estimated fair value of the conversion feature of the Working Capital Note as of issuance and for the period ended May 25, 2022 and 41,331 and $ 82,107 , respectively. The following are the primary assumptions used for the valuation of the conversion feature of the Working Capital Note: May 25, December 31, Warrant Valuation Terms Risk-free interest rate 2.72 % 4.70 % Expected term remaining (years) 5.32 0.46 Expected volatility 10.9 % 22.5 % Trading share price $ 9.77 $ 10.91 May 25, December 31, Compound Option Terms Strike price – debt conversion $ 1.00 $ 1.00 Strike price – warrants $ 11.50 $ 11.50 Term – debt conversion 0.32 0.01 Term – warrant conversion 5.32 5.01 Probability of consummation of a Business Combination 90 % 99 % Probability of consummation of a Business Combination – Target Date 11/30/2022 and 1/4/2023 90 % 99 % Probability of consummation of a Business Combination – Target Date 2/28/2023 and 1/31/2023 10 % 1 % The following table presents the changes in the fair value of the Level 3 conversion option: Fair value at May 25, 2022 (date of issuance) $ 41,331 Change in fair value 40,776 Fair value at December 31, 2022 $ 82,107 There were no transfers in or out of Level 3 f rom Note

The Business Combination On January 3, 2023 (the “Closing Date”), Cartesian Growth Corporation, a Cayman Islands exempted company (“Cartesian” or the “Company”), consummated the previously announced business combination (the “Business Combination”) pursuant to the terms of the Amended and Restated Business Combination Agreement, dated as of October 25, 2022 (as amended, supplemented, or otherwise modified from time to time, the “Business Combination Agreement”), by and among Cartesian, Rook MS LLC, a Delaware limited liability company (“Umbrella Merger Sub”), Tiedemann Wealth Management Holdings, LLC, a Delaware limited liability company (“TWMH”), TIG Trinity GP, LLC, a Delaware limited liability company (“TIG GP”), TIG Trinity Management, LLC, a Delaware limited liability company (“TIG MGMT” and, together with TIG GP, the “TIG Entities”), Alvarium Investments Limited, an English private limited company (“Alvarium” and, together with TWMH and the TIG Entities, the “Target Companies” and each a “Target Company”), and Alvarium Tiedemann Capital, LLC, a Delaware limited liability company (“Umbrella”). In connection with the Business Combination, Cartesian was renamed “Alvarium Tiedemann Holdings, Inc.” (the “Company”). As used herein, the “Company” refers to Cartesian Growth Corporation as a Delaware corporation by way of continuation following the Domestication and the Business Combination, which in connection with the Domestication and simultaneously with the Business Combination, changed its corporate name to “Alvarium Tiedemann Holdings, In c.” Prior to the Closing Date, the following transactions occurred pursuant to the terms of the Business Combination Agreement: • On December 30, 2022 (the business day before the Closing Date), Cartesian effected a deregistration under the Cayman Islands Companies Act (As Revised) and a domestication under Section 388 of the Delaware General Corporation Law, pursuant to which Cartesian’s jurisdiction of registration was changed from the Cayman Islands to the State of Delaware (the “Domestication”). As a result of and upon the effective time of the Domestication, among other things, each Class A ordinary share, par value $0.0001 per share, of Cartesian outstanding was converted into the right to receive one share of Class A common stock, par value $0.0001 per share, of Cartesian (the “Class A Common Stock”), and Cartesian was renamed “Alvarium Tiedemann Holdings, Inc.” • On January 3, 2023, TWMH and the TIG Entities effected a reorganization (the “TWMH/TIG Entities Reorganization”) such that TWMH and the TIG Entities became wholly owned direct or indirect subsidiaries of Umbrella and Umbrella became owned solely by the members of TWMH (the “TWMH Members”), the members of TIG GP (the “TIG GP Members”) and the members of TIG MGMT (the “TIG MGMT Members”); and • On January 3, 2023, Alvarium effected a reorganization such that Alvarium became the wholly owned indirect subsidiary of an Isle of Man entity (“Alvarium Topco”), and Alvarium Topco became owned solely by the shareholders of Alvarium (the “Alvarium Reorganization”). On the Closing Date, the following transactions occurred pursuant to the terms of the Business Combination Agreement: • TIG MGMT, TIG GP and Umbrella entered into a distribution agreement, pursuant to which (a) TIG MGMT distributed to Umbrella all of the issued and outstanding shares or partnership interests, as applicable, that it held through its strategic investments in External Strategic Managers, and (b) TIG GP distributed to Umbrella all of the issued and outstanding shares or interests that it held through its strategic investment in an External Strategic Manager; • Each shareholder of Alvarium Topco exchanged his, her or its (a) ordinary shares of Alvarium Topco and (b) class A shares of Alvarium Topco for Class A Common Stock (the “Alvarium Exchange”). Upon the consummation of the Alvarium Exchange, Alvarium Topco became a direct wholly-owned subsidiary of Cartesian; • Cartesian contributed shares of Class B Common Stock and cash to a newly formed wholly owned Delaware corporation (“Cartesian Holdco”) and Cartesian HoldCo subsequently contributed all shares of Class B Common Stock and cash to Umbrella Merger Sub; • Immediately following the effective time of the Alvarium Exchange, Umbrella Merger Sub merged with and into Umbrella, with Umbrella surviving such merger as an indirect subsidiary of Cartesian (the “Umbrella Merger”); • Immediately following the Alvarium Exchange and the Umbrella Merger, Cartesian and Umbrella entered into the Alvarium Contribution Agreement, pursuant to which (a) Cartesian contributed all of the issued and outstanding shares of Alvarium Topco that it held to Umbrella, (b) upon the consummation of the Alvarium Contribution, Alvarium Topco became a wholly-owned subsidiary of Umbrella; and • In accordance with the Sponsor Support Agreement, Cartesian simultaneously (i) canceled a number of SPAC Class A Ordinary Shares held by Sponsor equal to the number of Sponsor Redemption Shares and (ii) issued the Non-Redeeming Bonus Shares to holders of Non-Redeemed Cartesian Class A Common Shares on a pro-rata basis based on the number of Non-Redeemed SPAC Class A Common Shares held by such holders. The effective issuance rate of Non-Redeeming Bonus Shares was 0.121617 Non-Redeeming Bonus Share per Non-Redeemed SPAC Class A Common Share. Any fractional shares were rounded down to the nearest whole share. On January 3, 2023, following the Closing, Alvarium Holdings LLC (which was renamed Alvarium Tiedemann Holdings, LLC) became the wholly owned direct subsidiary of Umbrella. PIPE Investment As previously announced, on September 19, 2021, concurrently with the execution of the Business Combination Agreement, Cartesian entered into subscription agreements, as amended on October 25, 2022 (each, as amended, supplemented, or otherwise modified from time to time, a “Subscription Agreement”) with certain investors (collectively, the “PIPE Investors”) pursuant to which, on the terms and subject to the conditions therein, the PIPE Investors collectively subscribed for shares of Class A Common Stock (the “PIPE Shares”) at a purchase price of $ per share, for an aggregate purchase price equal to $ (the “PIPE Investment”). The PIPE Investment was consummated substantially concurrently with the closing of the Business Combination. Upon the Closing of the PIPE Investment, Cartesian simultaneously (i) canceled a number of SPAC Class A Ordinary Shares held by Sponsor equal to the number of Sponsor Redemption Shares and (ii) issued to the PIPE Investors an amount of shares equal to the number of PIPE Shares, divided by the sum of the number of the Non-Redeemed SPAC Class A Common Shares and the number of PIPE Shares, on a pro-rata basis based on the number of PIPE Shares held by such PIPE Investors (the “PIPE Bonus Shares”). Working Capital Loans On January 3, 2023, the outstanding working capital Note was paid in full.

Summary Of Significant Accoun_2

Summary Of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”).
Emerging Growth Company Status	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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 stockholder 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 statements 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	Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires 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 expenses during the reporting periods. 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. One of the more significant accounting estimates included in these financial statements is the determination of the fair value of the warrant liabilities. Such estimates may be subject to change as more current information becomes available and 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 had cash of $85,540 and $551,258 as of December 31, 2022 and 2021, respectively. The Company did not have any cash equivalents as of December 31, 2022 and 2021.
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 Deposit Insurance Corporation coverage. The Company has not experienced losses on this account.
Cash and Marketable Securities Held in Trust Account	Cash and Marketable Securities Held in Trust Account Through December 29, 2022 and at December 31, 2021, substantially all of the assets held in the Trust Account were held in money market funds which invest in U.S. Treasury securities. At December 31, 2022, substantially all of the assets held in the Trust account were transferred and held in the cash in preparation for the Business Combination closing date.
Convertible Debt	Convertible Debt The Company accounts for promissory note that feature conversion options in accordance with Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 815, “Derivatives and Hedging” (“ASC 815”). ASC 815 requires companies to bifurcate conversion options from their host instruments and account for them as freestanding derivative financial instruments according to certain criteria. These criteria include circumstances in which (i) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (ii) a promissory note that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable GAAP with changes in fair value reported in earnings as they occur and (iii) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument.
Warrant Liabilities	Warrant Liabilities The Company evaluates the Warrants (which are discussed in Note 3, Note 4 and Note 9), in accordance with FASB ASC Topic 815-40, “Derivatives and Hedging, Contracts in Entity’s Own Equity” (“ASC 815-40”) and concluded that a provision in its warrant agreement related to certain tender or exchange offers precludes the Warrants from being accounted for as components of equity. As the Warrants meet the definition of a derivative as contemplated in ASC 815-40, the Warrants are recorded as derivative liabilities on the balance sheets and measured at fair value at inception (the date of the IPO) and at each reporting date in accordance with FASB ASC Topic 820, “Fair Value Measurement,” with changes in fair value recognized in the statements of operations in the period of change
Offering Costs Associated with the Initial Public Offering	Offering Costs Associated with the Initial Public Offering The Company complies with the requirements of the FASBASC 340-10-S99-1. Offering costs consisted of legal fees, accounting fees, underwriting fees and other costs incurred through the IPO that were directly related to the IPO. Offering costs are allocated to the separable financial instruments issued in the IPO based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred, presented as non-operating expenses in the statements of operations. Offering costs associated with the Class A ordinary shares were charged to temporary equity upon the completion of the IPO.
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 ASC Topic 480 “Distinguishing Liabilities from Equity” (ASC 480). Ordinary shares subject to mandatory redemption (if any) are classified as a liability instrument and 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. All of the 34,500,000 Class A ordinary shares contain a redemption feature which allows for the redemption of such Class A ordinary shares in connection with the Company’s liquidation, if there is a shareholder vote or tender offer in connection with the Business Combination and in connection with certain amendments to the Company’s amended and restated memorandum and articles of association. In accordance with the SEC and its staff’s guidance on redeemable equity instruments, which has been codified in ASC 480-10-S99, redemption provisions not solely within the control of the Company require ordinary shares subject to redemption to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of ASC 480. Accordingly, at December 31, 2022 and 2021, all Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit 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. Increases or decreases in the carrying amount of redeemable ordinary shares are affected by charges against additional paid in capital and accumulated deficit. As of December 31, 2022 and 2021, the Class A ordinary shares subject to redemption reflected on the balance sheets are reconciled in the following table: Gross Proceeds $ 345,000,000 Less: Proceeds allocated to Public Warrants (15,007,500 ) Class A ordinary shares issuance costs (18,671,929 ) Plus: Remeasurement of carrying value to redemption value 33,679,429 Interest earned on Trust Account 31,308 Class A ordinary shares subject to possible redemption at December 31, 2021 $ 345,031,308 Interest earned on Trust Account 4,952,531 Class A ordinary shares subject to possible redemption at December 31, 2022 $ 349,983,839
Income Taxes	Income Taxes The Company accounts for income taxes under ASC 740, “Income Taxes” (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position 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 recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2022 and 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. There is currently no taxation imposed on income by the government of the Cayman Islands. In accordance with Cayman Islands income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.
Reconciliation of Net (Loss) Income per Share	Reconciliation of Net (Loss) Income per Share The Company’s net (loss) income is adjusted for the portion of net (loss) income that is allocable to each class of shares. The allocable net (loss) income is calculated by multiplying net (loss) income by the ratio of weighted average number of shares outstanding attributable to Class A ordinary shares and Class B ordinary shares to the total weighted average number of shares outstanding for the period. Remeasurement of the carrying value of Class A ordinary shares to redemption value is excluded from net (loss) income per ordinary share because the redemption value approximates fair value. Accordingly, basic and diluted (loss) income per ordinary share is calculated as follows: For the Year Ended For the Year Ended Class A Ordinary Shares Numerator: Net income (loss) allocable to Class A ordinary shares Net income (loss) $ 8,779,014 $ (1,035,380 ) Less: Allocation of net income (loss) to Class B ordinary shares (1,755,803 ) (232,904 ) Proportionate share of net income (loss) $ 7,023,211 $ (802,476 ) Denominator: Weighted Average Class A ordinary shares Basic and diluted weighted average shares outstanding 34,500,000 29,112,329 Basic and diluted net income (loss) per share $ 0.20 $ (0.03 ) Class B Ordinary Shares Numerator: Net income (loss) allocable to Class B ordinary shares Net income (loss) $ 8,779,014 $ (1,035,380 ) Less: Allocation of net income (loss) to Class A ordinary shares (7,023,211 ) (802,476 ) Proportionate share of net income (loss) $ 1, 755,803 $ (232,904 ) Denominator: Weighted Average Class B ordinary shares Basic and diluted weighted average shares outstanding 8,625,000 8,449,315 Basic and diluted net income (loss) per share $ 0.20 $ (0.03 )
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company follows the guidance in FASB ASC Topic 820, “Fair Value Measurement,” for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually. The fair value of certain 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 –Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Valuation adjustments and block discounts are not being applied. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these securities does not entail a significant degree of judgment. Level 2 –Valuations based on (i) quoted prices in active markets for similar assets and liabilities, (ii) quoted prices in markets that are not active for identical or similar assets, (iii) inputs other than quoted prices for the assets or liabilities, or (iv) inputs that are derived principally from or corroborated by market through correlation or other means. Level 3 –Valuations based on inputs that are unobservable and significant to the overall fair value measurement. See Note 9 for additional information on assets and liabilities measured at fair value.
Net (Loss) Income Per Share	Net Income (Loss) per Share The Company complies with the accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” Net (loss) income per share is computed by dividing net (loss) income by the weighted average number of ordinary shares outstanding during the period. The Company has two classes of shares, Class A ordinary shares and Class B ordinary shares. Earnings and losses are shared pro rata between the two classes of shares. The Company has not considered the effect of the 20,400,000 Class A ordinary shares underlying the 11,500,000 Warrants and the 8,900,000 Private Warrants, in the calculation of diluted net (loss) income per share, since the exercise of the Warrants is contingent upon the occurrence of future events. As a result, diluted net (loss) income per ordinary share is the same as basic net (loss) income per ordinary share for the period presented. The Company’s statements of operations apply the two-class method in calculating net (loss) income per share. Basic and diluted net (loss) income per Class A ordinary share and Class B ordinary share is calculated by dividing net (loss) income attributable to the Company by the weighted average number of Class A ordinary shares and Class B ordinary shares outstanding, allocated proportionally to each class of shares.
