DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS LGL Systems Acquisition Corp. (the “Company” or “LGL”) was incorporated in Delaware on April 30, 2019. The Company was formed for the purpose of entering into a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”). The Company was originally formed in Delaware under the name MTRON Systems Acquisition Corp. On August 19, 2019, the Company changed its name to LGL Systems Acquisition Corp. On March 12, 2021, LGL Systems Merger Sub Inc. (“Merger Sub”), a wholly owned subsidiary of the Company formed solely for the purpose of effectuating a Business Combination, was incorporated under the laws of Delaware. Although the Company is not limited to a particular industry or sector for purposes of consummating a Business Combination, the Company has focused its search on companies in the defense, aerospace and communications industries. On March 15, 2021, the Company entered into a definitive merger agreement for a Business Combination with IronNet Cybersecurity, Inc. (“IronNet”), which provides a suite of technologies that utilize real-time threat assessment and updates, behavioral modeling, big data analytics, and proactive threat detection and response capabilities as well as consulting services and training programs to protect against current and emerging cyber-threats. See Note 9 for further details regarding the merger agreement. 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 June 30, 2021, the Company had not commenced any operations. All activity through June 30, 2021 relates to the Company’s formation, the initial public offering (“Initial Public Offering”) and simultaneous private sale of warrants (“Private Warrants”), which is described below, and the Company’s search for a target for a Business Combination and the undertaking of related due diligence and negotiations. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates non-operating The registration statements for the Company’s Initial Public Offering were declared effective on November 6, 2019. On November 12, 2019, the Company consummated the Initial Public Offering of 17,250,000 units (the “Units” and, with respect to the shares of common stock included in the Units sold, the “Public Shares”), at $10.00 per Unit, which includes the full exercise by the underwriters of the over-allotment option to purchase an additional 2,250,000 Units, generating gross proceeds of $172,500,000, which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 5,200,000 Private Warrants at a price of $1.00 per Private Warrant in a private placement to LGL Systems Acquisition Holding Company, LLC (the “sponsor”), generating gross proceeds of $5,200,000, which is described in Note 4. Transaction costs amounted to $9,971,662, consisting of $3,450,000 of underwriting fees, $6,037,500 of deferred underwriting fees and $484,162 of other offering costs. As of June 30, 2021, cash of $471,185 was held outside of the Trust Account (as defined below) and is available for working capital purposes. Following the closing of the Initial Public Offering on November 12, 2019, an amount of $172,500,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Warrants was placed in a trust account (the “Trust Account”) located in the United States, which was 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 180 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of Rule 2a-7 The Company’s management has broad discretion with respect to the specific application of the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete a Business Combination having an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding taxes payable on income earned on the Trust Account and deferred underwriting commissions) at the time of the agreement to enter into an initial Business Combination. The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. The Company will provide its holders of the outstanding Public Shares (the “public stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account ($10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants, including the Private Warrants. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, solely if the Company seeks stockholder approval, a majority of the shares of the applicable classes are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Company’s sponsor has agreed to vote the Founder Shares (as defined in Note 5) and any Public Shares purchased after the Initial Public Offering in favor of approving a Business Combination and not to redeem any shares in connection with a stockholder vote to approve a Business Combination or sell any shares to the Company in a tender offer in connection with a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or do not vote at all. Notwithstanding the foregoing, if the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Amended and Restated Certificate of Incorporation will provide that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group”, will be restricted from redeeming its shares with respect to more than an aggregate of 20% or more of the Public Shares, without the prior consent of the Company. The sponsor has agreed (a) to waive its redemption rights with respect to its Founder Shares and Public Shares held by it in connection with the completion of a Business Combination or an amendment to the Company’s Certificate of Incorporation described below, (b) to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to consummate a Business Combination, and (c) not to propose an amendment to the Company’s Certificate of Incorporation to modify a public stockholders’ ability to convert or sell their shares to the Company in connection with a Business Combination or affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination within the required time period, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. The Company will have until November 12, 2021 (or such later date as may be approved by stockholders in an amendment to the Amended and Restated Certificate of Incorporation) to complete a Business Combination (the “Combination Period”). If the Company is unable to complete 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 business days thereafter, redeem the Public Shares, at a per-share In order to protect the amounts held in the Trust Account, the sponsor has agreed to 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 to below (i) $10.00 per Public Share and (ii) 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 $10.00 per share due to reductions in the value of the trust assets, less taxes payable, except as to any claims by a third party who executed an agreement with the Company waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of Initial Public Offering 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, 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, 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. Going Concern Consideration In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 205-40 Nasdaq Notification and Transfer of Listing On December 20, 2019, the Company received a notice from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market (“Nasdaq”) indicating that, based upon the Staff’s determination, the Class A common stock contained in the Company’s Units did not satisfy the minimum 300 round lot holders requirement for the listing of its units on The Nasdaq Capital Market, as set forth in the initial listing requirements of Nasdaq Listing Rule 5505(a)(3), or the minimum 300 public holders required for continued listing, as set forth in the continued listing requirements of Rule 5550(a)(3). The Company appealed the delisting letter to the Nasdaq Hearings Panel (“Panel”) and on February 12, 2020, the Panel issued its decision (“Decision”) to grant the Company’s request for continued listing, based on its finding that the Company has met the requirements for listing on Nasdaq. Notwithstanding the foregoing, effective March 13, 2020, the Company transferred the listing of its securities to the New York Stock Exchange (“NYSE”). The units, Class A common stock and warrants are now listed on the NYSE under the symbols “DFNS.U,” “DFNS” and “DFNS WS,” respectively.	NOTE 1.

Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	1. Organization and Summary of Significant Accounting Policies IronNet Cybersecurity, Inc. and subsidiaries (hereinafter “IronNet”, “we”, “us”, “our”, or the “Company”) provide a suite of technologies that provide real-time threat assessment and updates, behavioral modeling, big data analytics, and proactive threat detection and response capabilities as well as consulting services and training programs to protect against current and emerging cyber-threats. The Company’s fiscal year ends on January 31. References to fiscal 2022, for example, refer to the fiscal year ending January 31, 2022. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Registration Statement on Form S-4 Merger Agreement On August 26, 2021, IronNet Cybersecurity, Inc., a Delaware corporation (“Legacy IronNet”), LGL Systems Acquisition Corp., a Delaware corporation (“LGL”), and LGL Systems Merger Sub Inc., a Delaware corporation (“Merger Sub”), consummated the closing of the transactions contemplated by the Agreement and Plan of Reorganization and Merger, dated March 15, 2021 and as amended August 6, 2021, by and among Legacy IronNet, LGL and Merger Sub (the “Business Combination Agreement”), following their approval at a special meeting of the stockholders of LGL held on August 26, 2021. Pursuant to the terms of the Business Combination Agreement, a merger of Legacy IronNet and LGL was effected by the merger of Merger Sub with and into Legacy IronNet (the “Merger”), with Legacy IronNet surviving the Merger (the “Surviving Corporation”) as a wholly-owned subsidiary of LGL (the Merger, collectively with the other transactions described in the Business Combination Agreement, the “Business Combination”). Following the consummation of the Merger on the Closing Date, LGL changed its name from LGL Systems Acquisition Corp. to IronNet, Inc. (the “New Company”). Pursuant to the Business Combination Agreement, at the effective time of the Business Combination, (i) each outstanding share of Legacy IronNet common stock and Legacy IronNet preferred stock (with each share of Legacy IronNet preferred stock being treated as if it were converted into ten (10) shares of Legacy IronNet common stock on the effective date of the Business Combination) was converted into the right to receive (a) a number of shares of Company common stock equal to the Exchange Ratio (as defined below) and (b) a cash amount payable in respect of fractional shares of Company common stock that would otherwise be issued in connection with the foregoing conversion, if applicable, and (ii) each Legacy IronNet option, Legacy IronNet restricted stock unit, Legacy IronNet restricted stock award that was outstanding immediately prior to the closing of the Business Combination (and by its terms did not terminate upon the closing of the Business Combination) remains outstanding and (x) in the case of options, represents the right to purchase a number of shares of Company common stock equal to the number of shares of Legacy IronNet common stock subject to such option multiplied by the Exchange Ratio used for Legacy IronNet common stock (rounded down to the nearest whole share) at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent) and (y) in the case of restricted stock units and restricted stock awards, represent a number of shares of Company common stock equal to the number of shares of Legacy IronNet common stock subject to such restricted stock unit or restricted stock award multiplied by the Exchange Ratio (rounded down to the nearest whole share). In addition, Legacy IronNet stockholders and eligible holders of options, restricted stock unit awards and restricted stock awards (as applicable, only to the extent time vested as of the closing of the Business Combination) may also receive additional merger consideration in the form of a pro rata portion of 1,078 shares of Company common stock if the volume weighted average closing share price for the Company’s common stock equals or exceeds $13.00 for ten (10) consecutive days during the two-year The Exchange Ratio was 0.8141070 of a share of Company common stock per fully-diluted share of Legacy IronNet common stock. In connection with Special Meeting and the Business Combination, holders of 15,929 shares of LGL common stock, par value $0.0001 per share (“LGL Common Stock”), or 92.3% of the shares with redemption rights, exercised their right to redeem their shares for cash at a redemption price of approximately $10.03 per share, for an aggregate redemption amount of $159,764. Gross proceeds recorded from the merger were $138,250. The Company has capitalized certain transaction costs of $1,752 and $0 as of July 31, 2021, and January 31, 2021, respectively. Principles of Consolidation The condensed consolidated financial statements and accompanying notes are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and regulations of the U.S. Securities and Exchange Commission for interim financial reporting. The Company’s condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended January 31, 2021, and the related notes which provide a more complete discussion of the Company’s accounting policies and certain other information. The information as of January 31, 2021, included on the condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. The condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for a fair statement of the Company’s financial position as of July 31, 2021, and the results of operations for the three and six months ended July 31, 2021 and 2020, and cash flows for the six months ended July 31, 2021, and 2020. Use of Estimates The preparation of financial statements 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. Such estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results may differ from estimates under different assumptions or conditions. Segment and Geographic Information Segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”), in deciding how to allocate resources and access performance. The CODM reviews financial information presented on a consolidated basis for the purposes of allocating resources and evaluating financial performance. Accordingly, management has determined that the Company operates as one operating segment. The following table presents revenue by geographic location: Three months ended July 31, Six months ended July 31, 2021 2020 2021 2020 United States $ 5,523 $ 7,339 $ 10,985 $ 13,950 International 553 605 1,468 863 Total 6,076 7,944 12,453 14,813 Substantially all of the Company’s long-lived assets are located in the United States. Going Concern As of July 31, 2021, the Company had cash and cash equivalents of $14,107 and collectable receivables of $7,792. As of August 26, 2021, the Company had closed on its previously announced merger and secured gross funding of $138,250 through the closing of its merger. The Company based on its forecast and the proceeds from the recent merger has concluded that it will have sufficient liquidity to fund operations for the period ended 12 months from the issuance of these financial statements. The Company’s future capital requirements will depend on many factors, including, but not limited to the rate of our growth, our ability to attract and retain customers and their willingness and ability to pay for our products and services, and the timing and extent of spending to support our efforts to market and develop our products. Further, we may enter into future arrangements to acquire or invest in businesses, products, services, strategic partnerships, and technologies. As such, we may be required to seek additional equity or debt financing. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. If additional funds are not available to us on acceptable terms, or at all, our business, financial condition, and results of operations could be adversely affected. The financial statements do not include any adjustments that might become necessary should the Company be unable to continue as a going concern.

Organization and Summary of Significant Accounting Policies IronNet Cybersecurity, Inc. and subsidiaries (hereinafter “IronNet”, “we”, “us”, “our”, or the “Company”) provide a suite of technologies that provide real-time threat assessment and updates, behavioral modeling, big data analytics, and proactive threat detection and response capabilities as well as consulting services and training programs to protect against current and emerging cyber-threats. The Company was incorporated in the State of Delaware in May 2014. The Company’s headquarters is located in McLean, Virginia. The Company’s fiscal year ends on January 31. References to fiscal 2021, for example, refer to the fiscal year ending January 31, 2021. The significant accounting policies followed by the Company are described below. Principles of Consolidation The consolidated financial statements include the accounts of controlled subsidiaries and affiliates and have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). All intercompany transactions have been eliminated in consolidated. Foreign Currency Translation The United States Dollar (USD) is the functional currency of IronNet and our subsidiaries in the United States. Our subsidiaries’ financial statements are maintained in their functional currencies, which is the local currency in their country of origin. Our foreign subsidiaries’ financial statements are translated into USD using the exchange rate applicable to the dates of the financial statements. Assets and liabilities are translated into USD using the period-end Use of Estimates The preparation of financial statements 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. Such estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results may differ from estimates under different assumptions or conditions. Revenue Recognition The Company’s revenues are derived from sales of products, subscriptions, support and maintenance, and other services. Revenue is recognized when all of the following criteria are met: • Identification of the contract, or contracts, with a customer party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, (ii) the contract has commercial substance and the parties are committed to perform, and (iii) the Company determines that collection of substantially all consideration to which it will be entitled in exchange for goods or services that will be transferred is probable based on the customer’s intent and ability to pay the promised consideration. • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, we satisfy performance obligations Accounts Receivable Accounts receivable are generated from contracts with customers. Management determines the need for an allowance for doubtful accounts by evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. Management has evaluated the need for an allowance for doubtful accounts and no amounts were recorded as of January 31, 2021 and 2020, respectively. Deferred revenue (Contract Liabilities) Deferred revenue, which is a contract liability, consists of amounts for which we have the unconditional right to bill or advance from customers for which have not yet recognized revenue. We generally bill our customers in advance. To the extent the Company bills customers in advance of the contract commencement date, the accounts receivable and corresponding deferred revenue amounts are netted to zero on the consolidated balance sheets, unless such amounts have been paid as of the balance sheet date. Deferred costs The Company amortizes its contract fulfillment costs ratably over the contract term in a manner consistent with the related revenue recognition on that contract and are included in cost of revenue. These costs include appliance hardware and installation costs that are essential in providing the future benefit of the solution. Deferred Commissions Sales commissions contract are considered incremental and recoverable costs and are deferred and then amortized on a straight-line basis over the period of benefit determined to be between one and five years, which includes the contractual and expected renewal periods. The Company recognizes the incremental costs to initially obtain a contract with a customer on the statement of financial position if the Company expects the benefit of those costs to be longer than one year. Amortization expense is included in sales and marketing expenses in the accompanying consolidated statement of operations. Sales commissions paid upon renewal are substantially lower than the commissions paid to initially obtain the contract and are expensed in the period the contract is renewed. The majority of customer contracts are annual and as a result these renewals commissions are paid on an annual basis. Cash Equivalents The Company considers all highly-liquid instruments readily convertible into known amounts of cash with original maturities of three months or less to be cash equivalents. Investments The Company classifies our investments as available-for-sale The investment account was closed during FY 2021. The cost basis for short term and long term investments at January 31, 2020 are $1,398 and $0, respectively. Inventory Inventory is stated at the lower of cost (determined on a FIFO basis) or net realizable value. No provisions have been made to reduce slow-moving, obsolete or unusable inventories to their net realizable values for January 31, 2021 and 2020. Substantially all of our inventory is finished goods. Property and Equipment Property and equipment is stated at cost and depreciated over the assets estimated useful life using the straight-line method. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance, and repairs are charged to expense as incurred. The Company has incurred repair and maintenance charges of $10 and $67 for the years ended January 31, 2021 and 2020, respectively. When property and equipment is retired, or otherwise disposed of, the cost and accumulated depreciation and amortization is removed and any resulting gain or loss is included in the results of operations. Computer and other equipment 3-5 years Leasehold improvements Shorter of life of lease or life of asset Furniture and fixtures 7 years Software 3 years Software Development Costs Costs related to research, design and development of software products prior to establishment of technological feasibility are included in research and development as incurred. Software development costs, if material, are capitalized, beginning when a product’s technological feasibility has been established using the working model approach and ending when a product is available for general release to customers. The costs capitalized were $629 and $0 for the years ended January 31, 2021 and 2020, respectively. Research and Development Research and development costs are expensed in the year incurred and relate to new product developments and new features and are primarily personnel related costs and acquired software costs. These costs totaled $25,754 and $26,587 for the years ended January 31, 2021 and 2020, respectively. Advertising The Company expenses advertising costs as incurred. Advertising costs were $2,631 and $1,129 for the years ended January 31, 2021 and 2020, respectively and are included in the Sales and Marketing expenses. Stock-based Compensation The Company recognizes expense for stock-based compensation awards based on the estimated fair value of the award on the date of grant, which is amortized on a straight-line basis over the employee’s or director’s requisite service period, generally the vesting period of the award. The Company uses the Black-Scholes pricing model to estimate the fair value of options on the date of grant. The use of a valuation model requires management to make certain assumptions with respect to selected model inputs. The Company grants stock options at exercise prices determined equal to the fair value of common stock on the date of the grant. The fair value of the Company’s common stock at each measurement date is based on a number of factors, including the results of third-party valuations, the Company’s historical financial performance, and observable arms-length sales of the Company’s capital stock including convertible preferred stock, and the prospects of a liquidity event, among other inputs. The computation of expected option life is based on an average of the vesting term and the maximum contractual life of the Company’s stock options, as the Company does not have sufficient history to use an alternative method to the simplified method to calculate an expected life for employees. The Company estimates an expected forfeiture rate for stock options, which is factored into the determination of stock-based compensation expense. The volatility assumption is based on the historical and implied volatility of the Company’s peer group with similar business models. The risk-free interest rate is based on U.S. Treasury zero-coupon These estimates involve inherent uncertainties and the use of different assumptions may have resulted in stock-based compensation expense that was different from the amounts recorded. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company is subject to income taxes in U.S. federal jurisdictions and various state jurisdictions. Tax regulations within each jurisdiction are subject to interpretation of the related tax laws and regulations and require significant judgment to apply. The Company recognizes tax liabilities for uncertain tax positions when it is more likely than not that a tax position will not be sustained upon examination and settlement with various taxing authorities. Liabilities for uncertain tax positions are measured based upon the largest amount of benefit that is greater than 50% likely of being realized upon settlement. The guidance on accounting for uncertainty in income taxes also addresses de-recognition, Segment and Geographic Information Segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”), in deciding how to allocate resources and access performance. The CODM reviews financial information presented on a consolidated basis for the purposes of allocating resources and evaluating financial performance. Accordingly, management has determined that the Company operates as one operating segment. The Company presents financial information about its geographic areas in Note 10, Geographic Information, to the consolidated financial statements. Fair Value of Financial Instruments The fair value of the Company’s cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their carrying amounts due to the relatively short maturity of these items. Concentrations of Credit Risk The Company’s assets that are exposed to credit risk consist primarily of cash and cash equivalents and accounts receivable. Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed federally insured limits. The Company has never experienced any losses related to these balances. Amounts on deposit in excess of federally insured limits or accounts not included in federally insured limits at January 31, 2021 approximates $30,728. Accounts receivable consist primarily of amounts due from commercial entities. Historically, the Company has not experienced significant losses related to accounts receivable and, therefore, believes that the credit risk related to accounts receivable is minimal. Going Concern As of January 31, 2021, the Company had cash and cash equivalents of $31,543 and collectable receivables of $6,667. The Company completed its latest investment fund raising round in fiscal 2021, securing a total of $68,012 in new capital to further fund company operations. Nevertheless, the Company has incurred recurring losses from operations and expects to continue to incur significant costs in pursuit of its next round of financing in fiscal 2022 for capital funding purposes. Management plans to address this need for capital through that round of financing. Though the Company has had prior success in raising capital on favorable terms in its three previous rounds, the Company cannot assure that its plans to raise capital will be successful. These factors, when considered in the aggregate, raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might become necessary should the Company be unable to continue as a going concern. Recent Accounting Pronouncements not Yet Adopted The FASB issued ASU No. 2016-02, Leases 2016-02”), 2016-02 right-of-use short-term lease-related In June 2016, the FASB issued ASU 2016-13, In August 2018, the FASB issued ASU 2018-15, Internal-Use 350-40): implementation costs incurred to develop or obtain internal-use software. Further, the standard also requires the Company to expense the capitalized implementation costs of a hosting arrangement over the term of the hosting arrangement. This standard is effective for the Company for fiscal years beginning after December 15, 2020. Management will evaluate the potential impact of this guidance on its financial statements.

Stock Incentive Plan	4. Stock Incentive Plan The Company has a Stock Incentive Plan (the Stock Incentive Plan) under which, as of January 31, 2020, it may grant incentive stock options (ISOs), Restricted Stock Units (RSUs) and other equity securities to acquire, to convert into or to receive up to 36,250 shares of Class A common stock. As of July 31, 2021, there were 1,716 share equivalents that remained available to issue under the Stock Incentive Plan. All share equivalents issuable under the Stock Incentive Plan normally vest over a forty-eight With regard to stock option grants, the exercise price of each ISO granted under the Stock Option Plan may not be less than the fair market value per share of the underlying Class A common stock on the date of grant. The Board of Directors establishes the term and the vesting of all options issued under the Stock Option Plan; however, in no event will the term exceed ten The weighted-average assumptions for the six months ended July 31 are noted in the following table: Six Months Ended July 31, 2021 2020 Expected volatility 55.00 % 55.00 % Expected dividend yield 0.00 % 0.00 % Expected option term (in years) 2.0 2.0 Risk-free interest rate 0.14 % 0.23 % The expected volatility of the options granted was estimated using the historical volatility of share prices of publicly traded companies within the same or similar industry as a substitute for the historical volatility of the Company’s common shares, which is not determinable without an active external or internal market. The expected dividends are based on the Company’s historical estimated issuance and management’s expectations for dividend issuance in the future. The expected term of options granted represents the period of time that options granted are expected to be outstanding. The risk-free interest rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Presented below is a summary of the status of the stock options under the Stock Incentive Plan: Number Weighted Weighted Average Intrinsic (Years) (Years) Outstanding at February 1, 2021 2,680 $ 0.43 5.9 5,573 Granted — — — — Exercised (699 ) $ 0.42 5.4 4,689 Forfeited or expired (141 ) $ 0.47 5.8 — Outstanding at July 31, 2021 1,840 $ 0.43 5.4 12,348 Exercisable at July 31, 2021 1,786 $ 0.43 5.4 11,992 The Company recorded $10 and $25 of compensation cost related to stock options to operations during the three months ended and $27 and $56 for the six months ended July 31, 2021, and July 31, 2020, respectively. The Restricted Stock Units (RSUs) granted under the Stock Incentive Plan contain an additional vesting requirement that, in addition to the applicable time or performance vesting criteria noted above, also require the occurrence of a liquidity event. The requirements have not yet been met and therefore there is no expense recorded for the six months ended July 2021 and 2020. However, as of August 26, 2021, the Board approved the merger as the liquidity event, as further discussed in Note 12, Subsequent Events. They also have a life of seven years. Presented below is a summary of the status of outstanding RSUs, including showing the vesting status other than the liquidity event condition:​​​​​​​ Weighted Number Average of Grant Date Shares Fair Value Non-vested 11,930 $ 1.48 Granted 2,679 3.87 Vested (2,115 ) 1.63 Forfeited or expired (390 ) 2.77 Non-vested 12,104 $ 1.95 The fair value of each RSU was estimated on the date of grant using the Black-Scholes Option Pricing Model based on the same assumptions utilized for calculating fair market value of the stock options and utilizing the as converted equivalent price of securities issued during the period. As of July 31, 2021, there was approximately $36,236 of unrecognized compensation cost related to share-based compensation arrangements granted under the Stock Plan, of which $12 remained for options and $36,224 remained for RSUs, respectively. The company recognizes such compensation costs over a weighted-average period of four years for options and the period between the date of a liquidity event and four years for RSUs. The fair value of the shares under stock options granted that vested, net of forfeited vested, during the six months periods ended July 31, 2021, and 2020 totaled ($4,444) and $509, respectively.	6. Stock Incentive Plan The Company has a Stock Incentive Plan (the Stock Incentive Plan) under which, as of January 31, 2020, it may grant incentive stock options (ISOs), Restricted Stock Options (RSUs) and other equity securities to acquire, to convert into or to receive up to 36,250 shares of Class A common stock. As of January 31, 2021, there were 4,034 share equivalents that remained available to issue under the Stock Incentive Plan. All share equivalents issuable under the Stock Incentive Plan normally vest over a forty-eight With regard to stock option grants, the exercise price of each ISO granted under the Stock Option Plan may not be less than the fair market value per share of the underlying Class A common stock on the date of grant. The Board of Directors establishes the term and the vesting of all options issued under the Stock Option Plan; however, in no event will the term exceed ten years. The fair value of each stock option and restricted stock award was estimated on the date of grant using the Black-Scholes Option Pricing Model using the independent valuations of the company’s stock. The Company’s determination of the fair value of stock options and restricted stock options is affected by the Company’s stock price as well as a number of subjective and complex assumptions. These assumptions include the Company’s volatility, dividend yield, and risk-free interest rate. The weighted-average assumptions for the years ended January 31 are noted in the following table: 2021 2020 Expected volatility 55.0 % 50.0 % Expected dividend yield 0.0 % 0.0 % Expected option term (in years) 2.0 2.0 Risk-free interest rate 0.23 % 2.27 % The expected volatility of the options granted was estimated using the historical volatility of share prices of publicly traded companies within the same or similar industry as a substitute for the historical volatility of the Company’s common shares, which is not determinable without an active external or internal market. The expected dividends are based on the Company’s historical estimated issuance and management’s expectations for dividend issuance in the future. The expected term of options granted represents the period of time that options granted are expected to be outstanding. The risk-free interest rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Presented below is a summary of the status of the stock options under the Stock Incentive Plan: Number of Weighted Average Intrinsic Outstanding at February 1, 2019 5,173 $ 0.44 6.8 $ 4,431 Granted — — — Exercised (448 ) $ 0.41 6.4 $ 397 Forfeited or expired (301 ) $ 0.52 6.9 Outstanding at January 31, 2020 4,424 $ 0.44 6.9 $ 4,088 Exercisable at January 31, 2020 3,240 $ 0.41 6.7 $ 3,069 Outstanding at February 1, 2020 4,424 $ 0.44 5.9 $ 4,088 Granted — — — Exercised (495 ) $ 0.42 5.2 $ 468 Forfeited or expired (1,249 ) $ 0.46 6.1 Outstanding at January 31, 2021 2,680 $ 0.43 5.9 $ 5,573 Exercisable at January 31, 2021 2,450 $ 0.42 5.8 $ 5,116 The Company recorded $(6) and $171 of compensation cost related to stock options to operations during the years ended January 31, 2021 and January 31, 2020, respectively. During the year ended January 31, 2021, the number of forfeitures were higher than historical levels, which resulted in the Company revising its estimate for forfeitures from 28.1% to 41.1%. The Restricted Stock Units (RSUs) granted under the Stock Incentive Plan contain an additional vesting requirement that, in addition to the applicable time or performance vesting criteria noted above, also require the occurrence of a liquidity event. The requirements have not yet been met and therefore there is no expense recorded for RSU’s in fiscal year 2021 and 2020. They also have a life of seven years. Presented below is a summary of the status of outstanding RSUs, including showing the vesting status other than the liquidity event condition: Number Shares Weighted Non-vested at February 1, 2019 1,956 $ 1.29 Granted 17,159 1.33 Vested (1,117 ) 1.33 Forfeited or expired (314 ) 1.32 Non-vested at January 31, 2020 17,684 $ 1.32 Non-vested at February 1, 2020 17,684 $ 1.32 Granted 2,492 2.51 Vested (6,252 ) 1.38 Forfeited or expired (1,994 ) 1.68 Non-vested at January 31, 2021 11,930 $ 1.48 The fair value of each RSU was estimated on the date of grant using the Black-Scholes Option Pricing Model based on the same assumptions utilized for calculating fair market value of the stock options and utilizing the as converted equivalent price of securities issued during the period. As of January 31, 2021, there was $27,908 of unrecognized compensation cost related to share-based compensation arrangements granted under the Stock Incentive Plan, of which $44 remained for options and $27,864 remained for RSU’s, respectively. The Company recognizes such compensation costs over the term of each respective grant after taking into account historical forfeiture rates for options and starting at the time of a liquidity event, the period between the date of a liquidity event and the remainder of the vesting period for each RSU grant. The fair value of the shares under stock options granted that vested, net of forfeited vested, during the twelve-month period ending January 31, 2021 and January 31, 2020, totaled $(1,672) and $606, respectively.

Temporary Equity And Permanent Equity [Text Block]	7. Preferred Stock and Stockholders’ Deficit As of January 31, 2020, 145,747 of the Series B preferred shares were issued in the amount of $10,625 or $72.90 per share. During the year ended January 31, 2021, an additional 787 Series B preferred shares have been purchased at a price of $57,387. The total funds for the Series B funding round totaled $68,012. For the year ended January 31, 2021 and January 31, 2020, the Company repurchased 0 shares of common stock. The holders of Class A common stock (Class A Common), Class B common stock (Class B Common) (together Common Stock) and the holders of Series A preferred stock (Series A Preferred) and Series B preferred stock (Series B Preferred) (together Preferred Stock) have the following rights and preferences: Voting The holders of the Class A Common Stock and Class B Common Stock are entitled to one and twenty votes, respectively. Each holder of Preferred stock shall be entitled to the number of votes equal to the number of shares of Common Stock into which the shares of Preferred Stock could be converted and shall have voting rights and powers equal to the voting rights and powers of the Common Stock. Except as otherwise provided by the Articles of Incorporation or as required by law, holders of Preferred stock shall vote together with the Common Stock as a single class. Dividends The holders of Series A Preferred, in preference to the holders of Common Stock, shall be entitled to receive dividends at a rate of $2.45 per share of Series A Preferred. The holders of Series B Preferred, shall be entitled to receive dividends at a rate of $4.37 per share. Such dividends shall be payable only when, as and if declared by the Board of Directors. If the Corporation declares, pays or sets aside any dividends on shares of Common Stock, holders of Series A Preferred Stock, Series B Preferred Stock and Common Stock shall be entitled to share in such dividend pro rata based on the number of shares held by each such holder, treating for this purpose all such securities as if they had been converted to Common Stock pursuant to the terms of the Certificate of Incorporation immediately prior to such dividend. Liquidation In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company or Deemed Liquidation Event (defined as either a merger or consolidation, sale of assets, or the sale of the Company’s capital stock that the merger discussed in Footnote 16 will be considered a qualifiying event), before any distribution or payment shall be made to the holders of Common Stock, the holders of Series B Preferred and Series A Preferred shall be entitled to be paid an amount per share equal to the greater of (i) the Series B Preferred or Series A Preferred Original Issue Price, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series B Preferred or Series A Preferred have been converted into Common Stock (the Series B or Series A Liquidation Amount). The “Original Issue Price” applicable to the Preferred Stock shall mean, in the case of the Series A Preferred Stock, $40.95 per share and in the case of the Series B Preferred Stock, $72.90 per share. If upon any such liquidation the assets of the Company are insufficient to make payment in full to all holders of Series B and Series A Preferred to the full amount to which they are entitled, then such assets shall be distributed among the holders of Series B Preferred and Series A Preferred ratably in proportion to the full amounts to which they would otherwise be entitled if such amounts had been paid in full. Thereafter, the remaining assets of the Company legally available for distribution, if any, shall be distributed ratably only to the holders of Common Stock. Conversion Each share of Preferred stock is convertible, at the option of the holder thereof, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the applicable original issuance price by the applicable conversion price, as defined in the Second Amended and Restated Certificate of Incorporation. This conversion price is subject to adjustment under certain anti-dilutive events. Upon either (a) initial public offering of at least $75,000, or (b) the vote or written consent of the holders of at least sixty percent (60%) of the then outstanding shares of Series B and Series A Preferred shareholders, all outstanding shares of Preferred stock shall automatically be converted into shares of Common Stock at the then-effective conversion rate. In March 2021, the Company entered into a merger agreement, as discussed further in Note 16, Subsequent Events, that will lead to the conversion of the shares of Preferred stock into Common Stock as part of the merger. Redemption The Class A Common Stock, Class B Common Stock, Series A Preferred Stock and Series B Preferred Stock are not redeemable by any holder thereof. Warrants In April 2018, the Company issued warrants to purchase 6,859 shares of Series A Preferred Stock to a bank in connection with a debt arrangement. The warrants expire in April 2028. The warrants for Series A Preferred Stock are non-redeemable Subscription Notes Receivable During the year ended January 31, 2021, the Company issued no shares. During the year ended January 31, 2020, the Company issued 196 shares of common stock to certain employees of the Company in exchange for promissory notes (the Notes) totaling $95, which were determined to be recourse loans. The Notes accrue interest ranging from 1.40% to 2.70% compounded annually and are due three years from the initial date of the note agreement.

Restatement of Previously Issued Financial Statements	NOTE 2. RESTATEMENT OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS In April 2021, the Company concluded it should correct its accounting related to the Company’s outstanding warrants. The Company had initially accounted for the warrants as a component of equity, but upon further evaluation of the terms of the warrant, concluded that the warrants should be accounted for as liabilities. The warrants contain a restructuring price adjustment provision, such that, in the event the Company completes a business combination subsequent to the initial Business Combination which results in the Company’s shares no longer being listed on a national exchange or the OTC Bulletin Board, the exercise price of the warrants will decrease by a formula that causes the warrants to not be indexed to the Company’s own shares. As a result of this provision, the Company has restated its financial statements to reflect the Company’s warrants as liabilities with changes in the fair value recorded in the current period earnings. The table below summarizes the effect of the restatement to the Company’s financial statements for (i) its audited financial statements as of December 31, 2019, and for the period from April 30, 2019 (date of inception) to December 31, 2019, (ii) its audited financial statements as of December 31, 2020, and for the full year ended December 31, 2020 and (iii) its unaudited interim financial statements as of, and for the quarterly periods ended, March 31, 2020, June 30, 2020, and September 30, 2020: Previously Adjustments As Restated Balance sheet as of November 12, 2019 (audited) Total

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 Use of estimates The preparation of the condensed consolidated financial statements in conformity with 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 condensed consolidated 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 condensed consolidated 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 June 30, 2021 and December 31, 2020. Marketable securities held in Trust Account At June 30, 2021 and December 31, 2020, the assets were held in shares of a money market fund that invests primarily in U.S. Treasury Bills. For the six months ended June 30, 2021 and June 30, 2020, the Company withdrew interest income from the Trust Account of $172,214 and $188,762, respectively, to pay its franchise taxes. Common stock subject to possible redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s condensed consolidated balance sheets. Warrant liabilities The Company accounts for the 13,825,000 warrants (comprising of 8,625,000 Public Warrants and 5,200,000 Private Warrants) issued in connection with its Initial Public Offering in accordance with the guidance contained in ASC 815-40-15-7D. re-measurement Income taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 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 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 June 30, 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. The Company is subject to income tax examinations by major taxing authorities since inception.​​​​​​​ Net (loss) income per common share Our condensed consolidated statements of operations include a presentation of net (loss) income per share for common shares subject to possible redemption in a manner similar to the two-class non-redeemable Reconciliation of net (loss) income per common share The Company’s net (loss) income is adjusted for the portion of income that is attributable to common stock subject to possible redemption, as these shares only participate in the earnings of the Trust Account and not the income and losses of the Company. Accordingly, basic and diluted (loss) income per common share is calculated as follows: Three Months Three Months Net (loss) income $ (9,728,884 ) $ 690,075 Less: (Loss) income attributable to shares subject to possible redemption (1) 0 106,101 Adjusted net (loss) income attributable to common stock not subject to redemption $ (9,728,884 ) 583,975 Weighted average shares outstanding of common stock, basic and diluted 7,193,758 6,639,574 Basic and diluted net (loss) income per common share $ (1.35 ) $ 0.09 (Loss) income attributable to shares subject to possible redemption (1) $ 0 $ 106,101 Weighted average shares outstanding and subject to possible redemption, basic and diluted 14,368,742 14,922,926 Basic and diluted net (loss) income per common share $ 0.00 $ 0.01 (1) – includes interest income from cash held in the trust account; net of taxes paid or payable. Six Months Six Months Net (loss) income $ (4,945,383 ) $ 2,155,396 Less: (Loss) income attributable to shares subject to possible redemption (1) 0 512,427 Adjusted net (loss) income attributable to common stock not subject to redemption $ (4,945,383 ) $ 1,642,969 Weighted average shares outstanding of common stock, basic and diluted 7,432,762 6,691,776 Basic and diluted net (loss) income per common share $ (0.67 ) $ 0.25 (Loss) income attributable to shares subject to possible redemption (1) $ 0 $ 512,427 Weighted average shares outstanding and subject to possible redemption, basic and diluted 14,129,738 14,870,724 Basic and diluted net (loss) income per common share $ 0.00 $ 0.03 Concentration of credit risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times may exceed the Federal Deposit Insurance Corporation coverage of $250,000. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Fair value of financial instruments 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. As of June 30, 2021 and 2020, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses and income taxes payable approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account are comprised of investments in U.S. Treasury securities with an original maturity of 180 days or less or investments in a money market funds that comprise only U.S. treasury securities and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets. Recently issued accounting standards In August 2020, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2020-06, 470-20) 815-40): 2020-06”), 2020-06	NOTE 3. 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 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 Use of estimates The preparation of financial statements in conformity with 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 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, 2020 and 2019. Marketable securities held in Trust Account At December 31, 2020 and 2019, the assets were held in shares of a money market fund that invests primarily in U.S. Treasury Bills. For the year ended December 31, 2020, the Company withdrew $243,084 of interest income from the Trust Account to pay its franchise taxes. Common stock subject to possible redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet.​​​​​​​ Income taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 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 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, 2020 and 2019. 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 subject to income tax examinations by major taxing authorities since inception. Net loss per common share Our statement of operations includes a presentation of income (loss) per share for common shares subject to possible redemption in a manner similar to the two-class method of income (loss) per share. Net income per common share, basic and diluted, for common stock subject to possible redemption is calculated by dividing the proportionate share of income or loss on marketable securities held by the Trust Account, net of applicable franchise and income taxes, by the weighted average number of common stock subject to possible redemption outstanding since original issuance. Net income or loss per share, basic and diluted, for non-redeemable common stock is calculated by dividing the net income or loss, adjusted for income or loss on marketable securities attributable to common stock subject to possible redemption, net of applicable franchise and income taxes, by the weighted average number of nonredeemable common stock outstanding for the period. Nonredeemable common stock includes founder shares and nonredeemable shares of common stock as these shares do not have any redemption features. The Company has not considered the effect of warrants to purchase 13,825,000 shares of common stock that were sold in the Initial Public Offering and the private placement in the calculation of diluted loss per share, since the exercise of the warrants is contingent upon the occurrence of future events. As a result, diluted loss per share is the same as basic loss per share for the periods presented. Reconciliation of net loss per common share The Company’s net loss is adjusted for the portion of income that is attributable to common stock subject to possible redemption, as these shares only participate in the earnings of the Trust Account and not the income and losses of the Company. Accordingly, basic and diluted loss per common share is calculated as follows: For the For the Net loss $ (8,829,688 ) $ (1,079,160 ) Less: Income attributable to shares subject to possible redemption (1) 459,686 16,423 Net loss attributable to common stock not subject to possible redemption $ (9,289,374 ) $ (1,095,583 ) Weighted average shares outstanding of common stock, basic and diluted 6,703,614 4,346,765 Basic and diluted net loss per share, common share $ (1.39 ) $ (0.25 ) Income attributable to shares subject to possible redemption (1) $ 459,686 $ 16,423 Weighted average shares outstanding and subject to possible redemption, basic and diluted 14,858,886 2,965,735 Basic and diluted net loss per share, subject to possible redemption $ 0.03 $ 0.01 (1) – includes interest income from cash held in trust account; net of taxes paid or payable. Concentration of credit risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Fair value of financial instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. Recently issued accounting standards Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements. Warrant liabilities The Company accounts for the 13,825,000 warrants (comprising of 8,625,000 Public Warrants and 5,200,000 Private Warrants) issued in connection with its Initial Public Offering in accordance with ASC 815-40-15-7D. re-measurement sheet date until exercised, and any change in fair value is recognized in the Company’s statement of operations. The fair value of warrants issued by the Company in connection with the Public Offering has been determined using either the quoted price, if available, or was based on a Monte Carlo model. The private placement warrants have been determined based on a Monte Carlo model.​​​​​​​

In the event that a Business Combination does not close, the Company may use a portion of the 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.

WARRANT LIABILITIES	NOTE 8. WARRANT LIABILITIES As of both December 31, 2020 and 2019, the Company has 8,625,000 and 5,200,000 Public Warrants and Private Warrants, respectively, outstanding. Public Warrants may only be exercised for a whole number of shares. 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 or (b) November 12, 2020. No warrants will be exercisable for cash unless the Company has an effective and current registration statement covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of common stock. Under the terms of the warrant agreement, the Company has agreed that as soon as practicable, but in no event later than 15 business days after the closing of the initial Business Combination, the Company will use its best efforts to file a registration statement under the Securities Act covering such shares and maintain a current prospectus relating to the shares of Class A common stock issuable upon exercise of the warrants until the expiration of the warrants in accordance with the provisions of the warrant agreement. Notwithstanding the foregoing, if a registration statement covering the shares of common stock issuable upon exercise of the public warrants is not effective within 60 days following the consummation of a Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation. Once the warrants become exercisable, the Company may redeem the Public 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; • if, and only if, the reported last sale price of the Company’s common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like and subject to adjustment as described below) for any 20 trading days within a 30-trading • If, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying the warrants. If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of common stock at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the 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 warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless. The private warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the private warrants and the shares of common stock issuable upon the exercise of the private 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 warrants will be exercisable for cash or on a cashless basis, at the holder’s option, and be non-redeemable In addition, if (x) the Company issues additional shares of common stock or average trading price of the common stock during the 20 trading day period starting on the trading day prior to the day on which the Company consummated an initial 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 greater of (i) the Market Value or (ii) the price at which we issue the additional shares of common stock or equity-linked securities, and the $18.00 per share redemption trigger price of the warrants will be adjusted (to the nearest cent) to be equal to 180% of the greater of (i) the Market Value or (ii) the price at which we issue the additional shares of common stock or equity-linked securities.

Fair Value Measurements	5. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset in an orderly transaction or paid to settle a liability in an orderly transaction between market participants at the measurement date. Accounting standards utilize a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels, which are described below: • Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 – Observable inputs other than quoted prices that are either directly or indirectly observable for the asset or liability. • Level 3 – Unobservable inputs that are supported by little or no market activity. These levels are not necessarily an indication of the risk of liquidity associated with the financial assets or liabilities disclosed. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement, as required under ASC 820-10 Investments with an original maturity of three months or less at the date of purchase are considered cash equivalents, while all other investments are classified as short-term or long-term based on their maturities and their availability for use in current operations.

Fair Value Measurements		NOTE 8. FAIR VALUE MEASUREMENTS The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured non-financial re-measured 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. The following table presents information about the Company’s assets that are measured at fair value on a recurring basis at June 30, 2021 and December 31, 2020, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: Description Level June 30, December 31, Assets: Marketable securities held in Trust Account 1 $ 173,025,088 $ 173,192,131 Liabilities: Warrant liabilities – Public Warrants 1 $ 15,740,625 $ 13,972,500 Warrant liabilities – Private Warrants 3 $ 10,234,120 $ 9,464,000 Total Warrant Liabilities $ 25,974,745 $ 23,436,500 For those warrant liabilities within the Level 3 hierarchy, the Company utilizes a Monte Carlo simulation model to estimate a fair value. Any transfers to/from Levels 1, 2, and 3 are recognized at the end of the reporting period. There were no transfers between levels for the periods presented. Inherent in a Monte Carlo model are assumptions related to expected stock-price volatility, probability of completing a business combination, expected time until a business combination, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock based on historical volatility of select peer companies. The risk-free interest rate is based on the U.S. Treasury zero-coupon assumed to be equivalent to their remaining contractual term. The probability of completing a business combination is based on historical deals and current market conditions. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero. The following table provides quantitative information regarding Level 3 fair value measurement inputs as of their measurement dates: June 30, December 31, Stock price $ 9.99 $ 10.12 Term until business combination (in years) 0.21 0.35 Volatility Pre-merger 0.0 % 0.0 % Post-merger 27.64 % 36.01 % Risk-free rate 0.91 % 0.41 % Dividend yield — — Probability of completing a business combination 95.0 % 65.0 % The warrants are revalued on each reporting period, with changes in fair value recognized in the condensed consolidated statements of operations.

The Company uses a Monte Carlo simulation model for its Private Warrants since their issuance. For its Public Warrants, the Company also used a Monte Carlo simulation model since initial issuance through the first quarter of 2020 until an established market price for the Public Warrants was available on the NYSE exchange during the second quarter of 2020. Any transfers to/from Levels 1, 2, and 3 are recognized at the end of the reporting period. As such, in the second quarter of 2020, the Company transferred the Public Warrants out of Level 3 and into Level 2 at a with a fair value of $7,848,750. There were no transfers between levels for the period ended December 31, 2019. Inherent in a Monte Carlo model are assumptions related to expected stock-price volatility, probability of completing a business combination, expected time until a business combination, risk-free interest rate and dividend yield.

The Company recorded $8,797,500 for the Public Warrant liabilities and $5,668,000 for the Private Warrant liabilities upon their issuance on November 12, 2019. For the year ended December 31, 2020, the Company recognized a charge to the statement of operations resulting from an increase in the fair value of warrant liabilities of $8,971,000.

Income Taxes	7. Income Taxes The income tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate as adjusted for discrete items arising in that quarter. The effective income tax rate was (0.1)% and (0.1)% for the six months ended July 31, 2021 and 2020. The effective tax rate differs from the U.S. statutory rate primarily due to the full valuation allowances on the Company’s net domestic deferred tax assets and impact of foreign tax rate differential. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was enacted and signed into U.S. law to provide economic relief to individuals and businesses facing economic hardship as a result of the COVID-19	9. Income Taxes The provision for income taxes consists of the following for the years ended January 31: 2021 2020 Current income taxes Federal $ — $ — State 8 8 Foreign 69 3 Deferred income taxes — — Total income tax expense $ 77 $ 11 For the years ended January 31, 2021 and 2020, the foreign income (loss) before provision for income tax was $660 and $(1,123), respectively. For the years ended January 31, 2021 and 2020, the domestic loss before provision for income tax was $(55,956) and $(46,735), respectively. Indefinite reinvestment is determined by management’s judgment about and intentions concerning the future operations of the Company. As part of our business strategies, we have determined that, all earnings from our foreign continuing operations will be deemed indefinitely reinvested outside of the United States. Our plans to indefinitely reinvest certain earnings are supported by projected working capital and long-term capital requirements in each foreign subsidiary location in which the earnings are generated. A reconciliation of income tax expense at the U.S. federal statutory income tax rate to annual income tax expense at the Company’s effective tax rate is as follows: 2021 2020 Income tax expense computed at U.S. federal statutory income tax rate $ (11,628 ) 21.0 % $ (10,050 ) 21.0 % State income taxes (2,257 ) 4.1 % (1,951 ) 4.1 % Permanent items 321 -0.6 % 943 -2.0 % Valuation Allowance 13,632 -24.6 % 11,617 -24.3 % Other 9 0.0 % (548 ) 1.2 % Income tax expense computed at U.S. federal statutory income tax rate $ 77 -0.1 % $ 11 0.0 % Deferred income taxes reflect temporary differences in the recognition of revenue and expenses for income tax reporting and financial statement purposes. Significant components of the Company’s deferred tax assets (liabilities) are as follows: 2021 2020 Deferred tax assets Net operating loss carryforward $ 38,933 $ 25,296 Accruals and other 757 463 Intangibles 136 135 Depreciation and amortization 70 — Deferred Revenue 2,754 3,094 Gross deferred tax assets 42,650 28,988 Valuation allowance (41,849 ) (28,214 ) Net deferred tax asset 801 774 Deferred tax liabilities Depreciation and amortization — (23 ) Deferred costs (801 ) (751 ) Net deferred tax assets (liabilities) $ — $ — The table below details the activity of the deferred tax asset valuation allowance: Deferred tax asset valuation allowance Beginning Charged Deductions Ending Year Ended January 31, 2021 $ 28,214 13,635 — $ 41,849 January 31, 2020 $ 16,598 11,616 — $ 28,214 As of January 31, 2020 and January 31, 2019, the Company had net operating loss carryforwards (NOLs) available to offset federal taxable income of approximately $154,932 and $99,960 respectively. $25,270 of the federal NOLs expire on various dates through 2037 and $129,662 are able to be carried forward indefinitely to offset 80% of future taxable income. The company has tax effected state NOL carryforwards of approximately $6,223 as of January 31, 2021 and $4,051 as of January 31, 2020 that expire on various dates through 2037. In accordance with IRC Section 382, the extent to which net operating loss carryforwards can be used to offset future taxable income may be limited, depending on the extent of any ownership changes as defined by federal and various state and local jurisdictions. These limitations may result in the expiration of net operating loss carry forwards before utilization. In assessing the realizability of its net deferred tax assets, management considers whether it is more likely than not that some portion or all of the net deferred tax assets will be recognized. The ultimate realization of the net deferred tax assets is dependent upon the generation of taxable income during the periods in which temporary differences become deductible. Management considers taxes paid, if any, scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies that can be implemented by the Company in making this assessment. Based upon the level of historical taxable income, scheduled reversal of deferred tax liabilities, and projections for taxable income over the periods in which the temporary differences become deductible based on available tax planning strategies, management presently believes it is more likely than not that the Company may not realize all of the benefits of these deductible differences and, accordingly, has established a valuation allowance against the net deferred tax assets at January 31, 2021 and 2020. The Company recognizes a tax position taken or expected to be taken (and any associated interest and penalties) if it is more likely than not that it will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The Company measures the tax position at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Management evaluated all income tax positions and determined that there were no uncertain tax positions that required reserves as of January 31, 2021 and 2020. The Company files tax returns in the United States federal jurisdiction and in many state jurisdictions. The tax years 2017 through 2021 remain open to examination by the major taxing jurisdictions to which the company is subject. No examinations are currently open. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was enacted and signed into U.S. law to provide economic relief to individuals and businesses facing economic hardship as a result of the COVID-19

In accordance with Section 382 of the Internal Revenue Code, deductibility of any of the Company’s future NOLs may be subject to an annual limitation in the event of a change in control as defined under the regulations In assessing the realization of the deferred tax assets, management considers whether it is more likely than not that some portion of all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management determined that a valuation allowance was not required. A reconciliation of the federal income tax rate to the Company’s effective income tax rate at December 31, 2020 and 2019 is as follows: December 31, December 31, Statutory federal income tax rate 21.0 % 21.0 % State taxes, net of federal tax benefit 0.0 % 0.0 % Offering costs associated with warrants recorded as liabilities 0.0 % (9.6 )% Change in fair value of warrant liabilities (21.4 )% (8.9 )% Effective income tax rate (0.4 )% 2.5 % The Company files income tax returns in the U.S. federal jurisdiction and is subject to examination. The Company’s tax returns since inception remain open and subject to examination. On March 27, 2020, President Trump signed the Coronavirus Aid, Relief, and Economic Security “CARES” Act into law. The CARES Act includes several significant business tax provisions that, among other things, would eliminate the taxable income limit for certain net operating losses (“NOLs”) and allow businesses to carry back NOLs arising in 2018, 2019, and 2020 to the five prior years, accelerate refunds of previously generated corporate alternative minimum tax credits, generally loosen the business interest limitation under IRC section 163(j) from 30 percent to 50 percent, and allows businesses to immediately expense the full cost of Qualified Improvement Property, retroactive to tax years beginning on or after January 1, 2018. The Company does not believe that the CARES Act will have a significant impact on the Company’s financial position or statement of operations.

The condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for a fair statement of the Company’s financial position as of July 31, 2021, and the results of operations for the three and six months ended July 31, 2021 and 2020, and cash flows for the six months ended July 31, 2021, and 2020.		Principles of Consolidation The consolidated financial statements include the accounts of controlled subsidiaries and affiliates and have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). All intercompany transactions have been eliminated in consolidated.
Foreign Currency Translation			Foreign Currency Translation The United States Dollar (USD) is the functional currency of IronNet and our subsidiaries in the United States. Our subsidiaries’ financial statements are maintained in their functional currencies, which is the local currency in their country of origin. Our foreign subsidiaries’ financial statements are translated into USD using the exchange rate applicable to the dates of the financial statements. Assets and liabilities are translated into USD using the period-end
Use of estimates	Use of Estimates The preparation of financial statements 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. Such estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results may differ from estimates under different assumptions or conditions.

Such estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results may differ from estimates under different assumptions or conditions.
Revenue Recognition			Revenue Recognition The Company’s revenues are derived from sales of products, subscriptions, support and maintenance, and other services. Revenue is recognized when all of the following criteria are met: • Identification of the contract, or contracts, with a customer party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, (ii) the contract has commercial substance and the parties are committed to perform, and (iii) the Company determines that collection of substantially all consideration to which it will be entitled in exchange for goods or services that will be transferred is probable based on the customer’s intent and ability to pay the promised consideration. • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, we satisfy performance obligations
Accounts Receivable			Accounts Receivable Accounts receivable are generated from contracts with customers. Management determines the need for an allowance for doubtful accounts by evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. Management has evaluated the need for an allowance for doubtful accounts and no amounts were recorded as of January 31, 2021 and 2020, respectively.
Deferred revenue (Contract Liabilities)			Deferred revenue (Contract Liabilities) Deferred revenue, which is a contract liability, consists of amounts for which we have the unconditional right to bill or advance from customers for which have not yet recognized revenue. We generally bill our customers in advance. To the extent the Company bills customers in advance of the contract commencement date, the accounts receivable and corresponding deferred revenue amounts are netted to zero on the consolidated balance sheets, unless such amounts have been paid as of the balance sheet date.
Deferred costs			Deferred costs The Company amortizes its contract fulfillment costs ratably over the contract term in a manner consistent with the related revenue recognition on that contract and are included in cost of revenue. These costs include appliance hardware and installation costs that are essential in providing the future benefit of the solution.
Deferred Commissions			Deferred Commissions Sales commissions contract are considered incremental and recoverable costs and are deferred and then amortized on a straight-line basis over the period of benefit determined to be between one and five years, which includes the contractual and expected renewal periods. The Company recognizes the incremental costs to initially obtain a contract with a customer on the statement of financial position if the Company expects the benefit of those costs to be longer than one year. Amortization expense is included in sales and marketing expenses in the accompanying consolidated statement of operations. Sales commissions paid upon renewal are substantially lower than the commissions paid to initially obtain the contract and are expensed in the period the contract is renewed. The majority of customer contracts are annual and as a result these renewals commissions are paid on an annual basis.
Cash and cash equivalents			Cash Equivalents The Company considers all highly-liquid instruments readily convertible into known amounts of cash with original maturities of three months or less to be cash equivalents.
Investments			Investments The Company classifies our investments as available-for-sale The investment account was closed during FY 2021. The cost basis for short term and long term investments at January 31, 2020 are $1,398 and $0, respectively.
Inventory			Inventory Inventory is stated at the lower of cost (determined on a FIFO basis) or net realizable value. No provisions have been made to reduce slow-moving, obsolete or unusable inventories to their net realizable values for January 31, 2021 and 2020. Substantially all of our inventory is finished goods. Property and Equipment Property and equipment is stated at cost and depreciated over the assets estimated useful life using the straight-line method. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance, and repairs are charged to expense as incurred. The Company has incurred
Property and Equipment			repair and maintenance charges of $10 and $67 for the years ended January 31, 2021 and 2020, respectively. When property and equipment is retired, or otherwise disposed of, the cost and accumulated depreciation and amortization is removed and any resulting gain or loss is included in the results of operations. Computer and other equipment 3-5 years Leasehold improvements Shorter of life of lease or life of asset Furniture and fixtures 7 years Software 3 years
Software Development Costs			Software Development Costs Costs related to research, design and development of software products prior to establishment of technological feasibility are included in research and development as incurred. Software development costs, if material, are capitalized, beginning when a product’s technological feasibility has been established using the working model approach and ending when a product is available for general release to customers. The costs capitalized were $629 and $0 for the years ended January 31, 2021 and 2020, respectively.
Research and Development			Research and Development Research and development costs are expensed in the year incurred and relate to new product developments and new features and are primarily personnel related costs and acquired software costs. These costs totaled $25,754 and $26,587 for the years ended January 31, 2021 and 2020, respectively.
Advertising			Advertising The Company expenses advertising costs as incurred. Advertising costs were $2,631 and $1,129 for the years ended January 31, 2021 and 2020, respectively and are included in the Sales and Marketing expenses.
Stock-based Compensation			Stock-based Compensation The Company recognizes expense for stock-based compensation awards based on the estimated fair value of the award on the date of grant, which is amortized on a straight-line basis over the employee’s or director’s requisite service period, generally the vesting period of the award. The Company uses the Black-Scholes pricing model to estimate the fair value of options on the date of grant. The use of a valuation model requires management to make certain assumptions with respect to selected model inputs. The Company grants stock options at exercise prices determined equal to the fair value of common stock on the date of the grant. The fair value of the Company’s common stock at each measurement date is based on a number of factors, including the results of third-party valuations, the Company’s historical financial performance, and observable arms-length sales of the Company’s capital stock including convertible preferred stock, and the prospects of a liquidity event, among other inputs. The computation of expected option life is based on an average of the vesting term and the maximum contractual life of the Company’s stock options, as the Company does not have sufficient history to use an alternative method to the simplified method to calculate an expected life for employees. The Company estimates an expected forfeiture rate for stock options, which is factored into the determination of stock-based compensation expense. The volatility assumption is based on the historical and implied volatility of the Company’s peer group with similar business models. The risk-free interest rate is based on U.S. Treasury zero-coupon These estimates involve inherent uncertainties and the use of different assumptions may have resulted in stock-based compensation expense that was different from the amounts recorded.
Income taxes			Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company is subject to income taxes in U.S. federal jurisdictions and various state jurisdictions. Tax regulations within each jurisdiction are subject to interpretation of the related tax laws and regulations and require significant judgment to apply. The Company recognizes tax liabilities for uncertain tax positions when it is more likely than not that a tax position will not be sustained upon examination and settlement with various taxing authorities. Liabilities for uncertain tax positions are measured based upon the largest amount of benefit that is greater than 50% likely of being realized upon settlement. The guidance on accounting for uncertainty in income taxes also addresses de-recognition,
Segment and Geographic Information	Segment and Geographic Information Segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”), in deciding how to allocate resources and access performance. The CODM reviews financial information presented on a consolidated basis for the purposes of allocating resources and evaluating financial performance. Accordingly, management has determined that the Company operates as one operating segment. The following table presents revenue by geographic location: Three months ended July 31, Six months ended July 31, 2021 2020 2021 2020 United States $ 5,523 $ 7,339 $ 10,985 $ 13,950 International 553 605 1,468 863 Total 6,076 7,944 12,453 14,813 Substantially all of the Company’s long-lived assets are located in the United States.

Concentration of credit risk			balances may exceed federally insured limits. The Company has never experienced any losses related to these balances. Amounts on deposit in excess of federally insured limits or accounts not included in federally insured limits at January 31, 2021 approximates $30,728. Accounts receivable consist primarily of amounts due from commercial entities. Historically, the Company has not experienced significant losses related to accounts receivable and, therefore, believes that the credit risk related to accounts receivable is minimal.
Fair value of financial instruments			Fair Value of Financial Instruments The fair value of the Company’s cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their carrying amounts due to the relatively short maturity of these items. Concentrations of Credit Risk The Company’s assets that are exposed to credit risk consist primarily of cash and cash equivalents and accounts receivable. Cash and cash equivalents are maintained at financial institutions and, at times,
Going Concern	Going Concern As of July 31, 2021, the Company had cash and cash equivalents of $14,107 and collectable receivables of $7,792. As of August 26, 2021, the Company had closed on its previously announced merger and secured gross funding of $138,250 through the closing of its merger. The Company based on its forecast and the proceeds from the recent merger has concluded that it will have sufficient liquidity to fund operations for the period ended 12 months from the issuance of these financial statements. The Company’s future capital requirements will depend on many factors, including, but not limited to the rate of our growth, our ability to attract and retain customers and their willingness and ability to pay for our products and services, and the timing and extent of spending to support our efforts to market and develop our products. Further, we may enter into future arrangements to acquire or invest in businesses, products, services, strategic partnerships, and technologies. As such, we may be required to seek additional equity or debt financing. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. If additional funds are not available to us on acceptable terms, or at all, our business, financial condition, and results of operations could be adversely affected. The financial statements do not include any adjustments that might become necessary should the Company be unable to continue as a going concern.		Going Concern As of January 31, 2021, the Company had cash and cash equivalents of $31,543 and collectable receivables of $6,667. The Company completed its latest investment fund raising round in fiscal 2021, securing a total of $68,012 in new capital to further fund company operations. Nevertheless, the Company has incurred recurring losses from operations and expects to continue to incur significant costs in pursuit of its next round of financing in fiscal 2022 for capital funding purposes. Management plans to address this need for capital through that round of financing. Though the Company has had prior success in raising capital on favorable terms in its three previous rounds, the Company cannot assure that its plans to raise capital will be successful. These factors, when considered in the aggregate, raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might become necessary should the Company be unable to continue as a going concern.

Use of estimates		Use of estimates The preparation of the condensed consolidated financial statements in conformity with 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 condensed consolidated 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 condensed consolidated 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.

Common stock subject to possible redemption		Common stock subject to possible redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s condensed consolidated balance sheets.

The private placement warrants have been determined based on a Monte Carlo model.​​​​​​​
Income taxes		Income taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 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 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 June 30, 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. The Company is subject to income tax examinations by major taxing authorities since inception.​​​​​​​		Income taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases.

Net (loss) income per common share		Net (loss) income per common share Our condensed consolidated statements of operations include a presentation of net (loss) income per share for common shares subject to possible redemption in a manner similar to the two-class non-redeemable		Net loss per common share Our statement of operations includes a presentation of income (loss) per share for common shares subject to possible redemption in a manner similar to the two-class method of income (loss) per share. Net income per common share, basic and diluted, for common stock subject to possible redemption is calculated by dividing the proportionate share of income or loss on marketable securities held by the Trust Account, net of applicable franchise and income taxes, by the weighted average number of common stock subject to possible redemption outstanding since original issuance. Net income or loss per share, basic and diluted, for non-redeemable common stock is calculated by dividing the net income or loss, adjusted for income or loss on marketable securities attributable to common stock subject to possible redemption, net of applicable franchise and income taxes, by the weighted average number of nonredeemable common stock outstanding for the period. Nonredeemable common stock includes founder shares and nonredeemable shares of common stock as these shares do not have any redemption features. The Company has not considered the effect of warrants to purchase 13,825,000 shares of common stock that were sold in the Initial Public Offering and the private placement in the calculation of diluted loss per share, since the exercise of the warrants is contingent upon the occurrence of future events. As a result, diluted loss per share is the same as basic loss per share for the periods presented.
Reconciliation of net (loss) income per common share		Reconciliation of net (loss) income per common share The Company’s net (loss) income is adjusted for the portion of income that is attributable to common stock subject to possible redemption, as these shares only participate in the earnings of the Trust Account and not the income and losses of the Company. Accordingly, basic and diluted (loss) income per common share is calculated as follows: Three Months Three Months Net (loss) income $ (9,728,884 ) $ 690,075 Less: (Loss) income attributable to shares subject to possible redemption (1) 0 106,101 Adjusted net (loss) income attributable to common stock not subject to redemption $ (9,728,884 ) 583,975 Weighted average shares outstanding of common stock, basic and diluted 7,193,758 6,639,574 Basic and diluted net (loss) income per common share $ (1.35 ) $ 0.09 (Loss) income attributable to shares subject to possible redemption (1) $ 0 $ 106,101 Weighted average shares outstanding and subject to possible redemption, basic and diluted 14,368,742 14,922,926 Basic and diluted net (loss) income per common share $ 0.00 $ 0.01 (1) – includes interest income from cash held in the trust account; net of taxes paid or payable.

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

The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.
Fair value of financial instruments		Fair value of financial instruments 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. As of June 30, 2021 and 2020, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses and income taxes payable approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account are comprised of investments in U.S. Treasury securities with an original maturity of 180 days or less or investments in a money market funds that comprise only U.S. treasury securities and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets.		Fair value of financial instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature.

Pursuant to the Merger Agreement, Merger Sub will merge with and into IronNet, with IronNet surviving the merger. As a result of the Transactions, IronNet will become a wholly-owned subsidiary of LGL, with the stockholders of IronNet becoming stockholders of LGL and the Company will change its name to IronNet, Inc.

In connection with the merger, equityholders of IronNet will receive as merger consideration a number of shares of LGL common stock based on an exchange ratio (the “Exchange Ratio”), the numerator of which is equal to the quotient obtained by dividing $863,400,000 by $10.00, and the denominator of which is equal to the number of outstanding shares of IronNet on a fully diluted and as-converted basis. Holders of restricted stock units and restricted stock awards will receive LGL awards that provide for a number of shares of LGL common stock equal to the number of IronNet shares subject to the awards, multiplied by the Exchange Ratio. Holders of IronNet options and warrants outstanding will receive LGL options and warrants exercisable for a number of shares of LGL common stock equal to the number of IronNet shares subject to the options and warrants, multiplied by the Exchange Ratio (adjusted to be on an as-converted to common stock basis), at an exercise price per share equal to the prior per share exercise price, divided by the Exchange Ratio (adjusted to be on an as-converted to common stock basis). Consummation of the merger is conditioned on approval thereof by the Company’s and IronNet’s stockholders, a minimum of $125 million of available cash (inclusive of cash in the trust account (net of redemptions) and the $125 million of cash proceeds received from the Private Placement (see paragraph below) and other customary closing conditions.In connection with the execution of the Merger Agreement, the Company entered into subscription agreements (the “Subscription Agreements”) with certain investors (the “PIPE Investors”).
