Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS	DESCRIPTION OF BUSINESS SpringBig Holdings, Inc. and its wholly-owned subsidiaries (the “Company,” “we,” “us,” or “SpringBig”) developed a software platform that provides marketing and customer engagement services to cannabis dispensaries and brands throughout the United States and Canada. The Company allows merchants to provide loyalty plans and rewards directly to consumers through an internet portal and mobile applications. Our operational headquarters are in Boca Raton, Florida, with additional offices located in the United States and Canada. The Company has one direct wholly-owned subsidiary, SpringBig, Inc. On June 14, 2022 (the “Closing Date”), SpringBig Holdings, Inc. (formerly known as Tuatara Capital Acquisition Corporation (“Tuatara” or “TCAC”)), consummated the previously announced business combination of SpringBig, Inc. (“Legacy SpringBig”) and HighJump Merger Sub, Inc., the wholly-owned subsidiary of Tuatara, pursuant to the Amended and Restated Agreement of Plan Merger, dated as of April 14, 2022, as amended, by and among Tuatara, HighJump Merger Sub, Inc. and Legacy SpringBig. Prior to the closing of the business combination (the “Closing”), Tuatara changed its jurisdiction of incorporation by deregistering as a Cayman Islands exempted company and continuing and domesticating as a corporation incorporated under the laws of the State of Delaware. In connection with the Closing, the registrant changed its name from Tuatara Capital Acquisition Corporation to “SpringBig Holdings, Inc.” SpringBig will continue the existing business operations of Legacy SpringBig as a publicly traded company. See Note 8, Business Combination, to these consolidated financial statements for further information. While the legal acquirer in the business combination is SpringBig for financial accounting and reporting purposes under U.S. GAAP, Legacy SpringBig is the accounting acquirer, with the merger accounted for as a “reverse recapitalization.” A reverse recapitalization does not result in a new basis of accounting, and the financial statements of the combined entity represent the continuation of the financial statements of Legacy SpringBig. Under this accounting method, SpringBig is treated as the “acquired” company and Legacy SpringBig is the accounting acquirer, with the transaction treated as a recapitalization of Legacy SpringBig. SpringBig’s assets, liabilities and results of operations were consolidated with Legacy SpringBig’s beginning on the date of the business combination. Except for certain warrant liabilities, the assets and liabilities of SpringBig were recognized at historical cost (which is consistent with carrying value) and were not material, with no goodwill or other intangible assets recorded. The warrant liabilities, which are discussed in Note 11, Warrant Liabilities, were recorded at fair value. The consolidated assets, liabilities, and results of operations of Legacy SpringBig became the historical financial statements, and operations prior to the closing of the business combination presented for comparative purposes are those of Legacy SpringBig. Pre-merger shares of common stock and preferred stock of Legacy SpringBig were converted to shares of common stock of the combined company using the conversion ratio of 0.59289 and for comparative purposes, the shares and net loss per share of Legacy SpringBig prior to the merger have been retroactively restated using the conversion ratio. Beginning June 15, 2022, the ticker symbols for the Company’s common stock and publicly-traded warrants were changed to “SBIG” and “SBIGW,” respectively, and commenced trading on The Nasdaq Global Market. The Company received net proceeds of $18.8 million, with gross proceeds of $25.1 million, which were in addition to the $7.0 million in Convertible Notes proceeds, which were received in February 2022 in connection with Legacy SpringBig’s issuance of such notes (and which Convertible Notes and the interest due thereon were converted into common stock in connection with the business combination. See Note 9, 15% Convertible Promissory Notes, to these consolidated financial statements). Of the amount received at the Closing, approximately $8.8 million represented cash from the TCAC trust related to unredeemed shares; $6.1 million represented proceeds from the subscription for common stock from certain investors (the “PIPE Financing”), and $10.0 million from the Secured Convertible Note (defined below). The Company incurred additional cash and non cash expenses totaling $8.6 million, resulting in net business combination proceeds of $10.2 million. Common Stock Purchase Agreement On April 29, 2022, the Company entered into a Common Stock Purchase Agreement (as amended, the “Stock Purchase Agreement”) with CF Principal Investments LLC ("Cantor"), an affiliate of Cantor Fitzgerald L.P. The Company, in its sole discretion, shall have the right, but not the obligation, to issue and sell to the Cantor, and

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The unaudited consolidated financial statements have been prepared in conformity with the rules and regulations of the SEC for Quarterly Reports on Form 10-Q and therefore do not include certain information, accounting policies, and footnote disclosure information or footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with generally accepted accounting principles. However, all adjustments (consisting of normal recurring accruals), which, in the opinion of management, are necessary for a fair presentation of the financial statements, have been included. Operating results for the three months ended June 30, 2022 and the six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for future periods or for the year ending December 31, 2022. These interim financial statements should be read in conjunction with the Company's audited consolidated financial statements and accompanying notes included in the Company’s Registration Statement on Form S-1 filed with the SEC on July 22, 2022 and the audited financial statements and notes thereto included in the Annual Report on Form 10-K of Tuatara for the fiscal year ended December 31, 2021. Going Concern and Liquidity Historically, the Company has incurred losses, which has resulted in an accumulated deficit of approximately $18.7 million as of June 30, 2022. Cash flows used in operating activities were $5.0 million and $2.5 million for the six months ended June 30, 2022 and 2021, respectively. As of June 30, 2022, the Company had approximately $14.0 million in working capital, inclusive of $14.2 million in cash and cash equivalents to cover overhead expenses. The Company’s ability to continue as a going concern is dependent on its ability to meet its liquidity needs through a combination of factors but not limited to, cash and cash equivalents, the ongoing increase in revenue through increased usage by customers and new customers, its Stock Purchase Agreement and strategic capital raises. The ultimate success to these plans is not guaranteed. Based on management projections for increases in revenue and cash on hand, we estimate that our liquidity and capital resources are sufficient for our current and projected financial needs for the next twelve months, at a minimum. The accompanying consolidated financial statements are prepared on a going concern basis and do not include any adjustments that might result from uncertainty about the Company’s ability to continue as a going concern. Foreign Currency We translate the financial statements of our foreign subsidiaries, which have a functional currency in the respective country’s local currency, to U.S. dollars using month-end exchange rates for assets and liabilities and actual exchange rates for revenue, costs and expenses on the date of the transaction. Translation gains and losses are included within “general and administrative expense” on the consolidated statements of operations. These gains and losses are immaterial to the financial statements. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and various other assumptions believed to be reasonable. The Company’s significant estimates include, but are not limited to, the allowance for doubtful accounts, useful lives of deferred contract assets, intangible assets, property and equipment, deferred income tax asset valuation, and certain assumptions used in the valuation for equity awards, convertible notes and warrant liabilities. Future events and their effects cannot be predicted with certainty; accordingly, accounting estimates require the exercise of judgment. Accounting estimates used in the preparation of these financial statements change as new events occur, as more experience is acquired, as additional information is obtained, and as the operating environment changes. Actual results may differ materially from these estimates. Concentrations of Credit Risk Financial instruments that potentially subject us to concentration of credit risk consist principally of cash and cash equivalents and accounts receivable. We place our cash and cash equivalents with high credit-quality financial institutions. Such deposits may be in excess of federally insured limits. To date, we have not experienced any losses on our cash and cash equivalents. We perform periodic evaluations of the relative credit standing of the financial institutions. We perform ongoing credit evaluations of our customers’ financial condition and require no collateral from our customers. We maintain an allowance for doubtful accounts receivable based upon the expected collectability of accounts receivable balances. During the three and six months ended June 30, 2022, we had one customer representing 13% concentration of revenue, within the United States with 15% and 13% for the three and six months June 30, 2021, respectively. At June 30, 2022 and December 31, 2021 we had one customer representing 6% and 28% of accounts receivable within the United States, respectively. Transaction Costs The Company incurred significant costs direct and incremental to the business combination and therefore to the recapitalization of the Company. We deferred such costs incurred in 2021. In 2022, upon closing of the business combination, total direct transaction costs were allocated between equity and liability instruments measured at fair value on a recurring basis that were newly issued in the recapitalization. Amounts allocated to equity were recorded to additional paid-in capital, while amounts allocated to the specified liabilities were recorded as other expense. See Note 8, Business Combination, to these consolidated financial statements for further information. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less, when acquired, to be cash equivalents. The Company maintains its cash with one commercial bank. As of June 30, 2022 and December 31, 2021, the Company exceeded the federally insured limits of $250,000 for interest and noninterest bearing deposits. The Company had cash balances with a single financial institution in excess of the FDIC insured limits by amounts of $13.9 million and $1.9 million as of June 30, 2022 and December 31, 2021, respectively. We monitor the financial condition of such institution and have not experienced any losses associated with these accounts. Effective Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The amendments in this update modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. This update is effective beginning after December 15, 2021. We adopted this standard on January 1, 2022. The adoption of this standard did not have a material impact on our consolidated financial statements for the period ended June 30, 2022. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The ASU enhances and simplifies various aspects of the income tax accounting guidance in ASC 740, including requirements related to the following: (1) hybrid tax regimes; (2) tax basis step-up in goodwill obtained in a transaction that is not a business combination; (3) separate financial statements of entities not subject to tax; (4) intra-period tax allocation exception to the incremental approach; (5) ownership changes in investments; (6) interim-period accounting for enacted changes in tax law; and (7) year-to-date loss limitation in interim-period tax accounting. The amendments in ASU 2019-12 are effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods therein. This update is effective beginning after December 15, 2021. We adopted this standard on January 1, 2022. The adoption of this standard did not have a material impact on our consolidated financial statements for the period ended June 30, 2022. In January 2020, the FASB issued ASU 2020-01, Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 . The amendments in this update clarify certain interactions between the guidance to account for certain equity securities. This update is effective beginning after December 15, 2021. We adopted this standard on January 1, 2022. The adoption of this standard did not have a material impact on our consolidated financial statements for the period ended June 30, 2022. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity . Under ASU 2020-06, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives, or that do not result in substantial premiums accounted for as paid-in capital. The convertible debt instruments will now be accounted for as a single liability measured at amortized cost. This results in the interest expense recognized for convertible debt instruments to be closer to the coupon interest rate. The new guidance also requires the if-converted method to be applied for all convertible instruments when calculating earnings per share. This update is effective beginning after December 15, 2021. We adopted this standard on January 1, 2022. The adoption of this standard did not have a material impact on our consolidated financial statements for the period ended June 30, 2022. Recent Accounting Pronouncements Not Yet Adopted In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) . FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Certain qualitative and quantitative disclosures are required, as well as a retrospective recognition and measurement of impacted leases. In June 2020, FASB issued ASU 2020-05, Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Deferral of the Effective Dates for Certain Entities , which deferred the effective date of ASU 2016-02 to annual reporting periods beginning after December 15, 2021, with early adoption permitted. In July 2021, the FASB released Update No. 2021-05 Lessors—Certain Leases with Variable Lease Payments . The amendments in this update affect lessors with lease contracts that (1) have variable lease payments that do not depend on a reference index or a rate and (2) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing. The amendments in this update amend Topic 842. The amendments are effective for fiscal years beginning after December 15, 2021, for all entities, and interim periods within those fiscal years for public business entities and interim periods within fiscal years beginning after December 15, 2022, for all other entities. Management is currently evaluating the impact of adopting this standard on our financial condition and results of operations . In June 2016, FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , to revise the criteria for the measurement, recognition, and reporting of credit losses on financial instruments to be recognized when expected. In November 2019, FASB issued ASU 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) , which deferred the effective date of ASU 2016-13 to annual reporting periods beginning after December 15, 2022, with early adoption permitted. Management is currently evaluating the impact of adopting this standard on our financial condition and results of operations . In October 2021, the FASB issued ASU 2021-08 - Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customer s. The amendments in this update require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The amendments in this update should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendments is permitted, including adoption in an interim period. An entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. Management is currently evaluating the impact of adopting this standard on our financial condition and results of operations .

Share-Based Payment Arrangement [Abstract]
STOCK BASED COMPENSATION	STOCK BASED COMPENSATION At the Special Meeting, in connection with the business combination, the Tuatara shareholders approved the SpringBig Holdings, Inc. 2022 Long-Term Incentive Plan (the “2022 Incentive Plan”), which became effective upon the Closing. The purpose of the 2022 Incentive Plan is to secure and retain the services of employees, directors and consultants, to provide incentives for such persons to exert maximum efforts for our success and to provide a means by which such persons may be given an opportunity to benefit from increases in value of the common stock through the granting of awards thereunder. We believe that the equity-based awards to be issued under the 2022 Incentive Plan will motivate award recipients to offer their maximum effort to us and help them focus on the creation of long-term value consistent with the interests of our shareholders. We believe that grants of incentive awards are necessary to enable us to attract and retain top talent. The number of shares of our common stock initially reserved for issuance under the 2022 Incentive Plan was 1,525,175, which equaled the amount of shares of our common stock equal to 5% of the sum of (i) the number of shares of our common stock outstanding as of the Closing and (ii) the number of shares of our common stock underlying stock options issued under the SpringBig, Inc. 2017 Equity Incentive Plan (as amended and restated) (the “Legacy Incentive Plan”) that were outstanding as of the Closing. Shares subject to stock awards granted under the 2022 Incentive Plan that expire or terminate without being exercised in full, or that are paid out in cash rather than in shares, will not reduce the number of shares available for issuance under the 2022 Incentive Plan. Prior to the closing of the merger, Legacy SpringBig maintained an equity incentive plan (the “Legacy Incentive Plan”), which was originally established effective December 1, 2017. The Legacy Incentive Plan permitted the grant of incentive stock options, non-qualified stock options, restricted stock awards, and restricted stock unit awards to Legacy SpringBig and its affiliates’ employees, consultants and directors. SpringBig will not grant any additional awards under the Legacy Incentive Plan following the business combination. During the three months ended June 30, 2022 and 2021, compensation expense recorded in connection with the Legacy Incentive Plan was $1.0 million and $119,000, respectively and $1.2 million and $237,000 for the six months ended June 30, 2022 and 2021, these are included in administrative expense on the statements of operations. The following table summarizes information on stock options outstanding as of June 30, 2022 and 2021 under the Legacy Incentive Plan: Options Outstanding Options Vested and Exercisable Fixed Options Number of Options Weighted Average Exercise Price (Per Share) Number of Options Weighted Average Remaining Contractual Life (Years) Weighted Average Exercise Price (Per Share) Outstanding Balance, January 1, 2022 6,802,437 $ 0.38 4,628,311 6.79 $ 0.24 Options granted — Options exercised (530,666) $ 0.55 Options forfeited (61,460) $ 0.75 Options cancelled (4,791) $ 0.75 Outstanding Balance, June 30, 2022 6,205,520 Conversion ratio 0.5929 SpringBig Holdings options 3,679,171 0.58 3,486,482 — — The intrinsic value of the options exercised during the six months ended June 30, 2022 was $3.3 million, no option was exercised during the same period for 2021. With the consummation of the business combination, all outstanding options were vested with the exception of 192,689 options granted to certain executives of the Company. The cost associated with the early vesting was $924,000 and is included in administrative expense on the statement of operations. The remaining unamortized expenses associated with the unvested options is $173,000 and will be expensed with the next 3 years. During the six months ended June 30, 2022 and 2021, the Company used the Black-Scholes option-pricing model to value option grants and to determine the related compensation expense. The assumptions used in calculating the fair value of stock-based payment awards represent management’s best estimations. The Company based its expected volatility based on the volatilities of certain publicly traded peer companies. The risk-free interest rate used for each grant is equal to the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life. The expected term of options granted was determined based on the expected holding period at the time of the grant. GAAP also requires that the Company recognize compensation expense for only the portion of options that are expected to vest. Therefore, the Company has estimated expected forfeitures of stock options. In developing a forfeiture rate estimate, the Company considered its historical experience. If the actual number of forfeitures differs from those estimated by management, additional adjustments to compensation expense may be required in future periods.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Valuation is based on unadjusted quoted prices in active markets for identical assets and liabilities that are accessible at the reporting date. Because valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2 : Valuation is determined from pricing inputs that are other than quoted prices in active markets that are either directly or indirectly observable as of the reporting date. Observable inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and interest rates and yield curves that are observable at commonly quoted intervals. Level 3 : Valuation is based on inputs that are both significant to the fair value measurement and unobservable. Level 3 inputs include situations where there is little, if any, market activity for the financial instrument. The inputs into the determination of fair value generally require significant management judgment or estimation. . Liabilities measured at fair value on a recurring basis The balances of the Company’s liabilities measured at fair value on a recurring basis as of June 30, 2022, are as follows (in thousands): Level 1 Level 2 Level 3 Total Fair Value Liabilities: Senior secured convertible note $ — $ — $ 9,843 $ 9,843 Private warrants — 606 — 606 Public warrants 1,010 — — 1,010 $ 1,010 $ 606 $ 9,843 $ 11,459 The following is a description of the methodologies used to estimate the fair values of liabilities measured at fair value on a recurring basis and within the fair value hierarchy which is warrant and senior secured convertible note. Warrant liabilities Prior to the business combination, TCAC issued warrants to purchase 10,000,000 Class A ordinary shares at a price of $11.50 per whole share, as part of the units offered by the prospectus for their initial public offering and, simultaneously with the closing of their initial public offering, issued in a private placement an aggregate of 6,000,000 private placement warrants, each exercisable to purchase one Class A ordinary share at a price of $11.50 per share. The Company utilize a fair value approach to account for its warrants based on the quoted price at June 30, 2022, the calculation is consistent with ASC 820, Fair Value Measurement, with changes in fair value recorded in current earnings. The Company performed a valuation at June 30, 2022 resulting in a value of approximately $1.6 million using a closing price of $0.101 for the public and private warrants. Senior secured convertible notes In connection with the business combination, on June 14, 2022, the Company issued $11.0 million in aggregate principal amount of Secured Convertible Notes, issued at a discount of $1.0 million, with proceeds of $10.0 million received on the Closing Date. Additionally, the Company entered into a warrant agreement with the holders for a warrant to purchase 586,980 shares with an initial exercise price of $12.00. The Company determined that the Secured Convertible Notes meet the variable share obligations requirements under ASC 480, Distinguishing Liabilities From Equity , as a result is classified as a liability measure at fair value, with changes in fair value recognized in earnings. The Company adopted ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity and elected to carry the Secured Convertible Notes along with the Convertible Warrant at fair value. The fair value is determined in accordance with ASC 820, Fair Value Measurement, utilizing the discount, interest rate and the fair value of the associated warrants. Changes in Fair Value The following tables provides a roll-forward in the changes in fair value for the six months ended June 30, 2022, for all liabilities for which the Company determines fair value on a recurring basis (in thousands): Warrants Balance, January 1, 2022 $ — Assumed in business combination 4,496 Change in fair value (2,880) Balance, June 30, 2022 $ 1,616 Changes in fair value included in earnings for the period relating to liabilities held at June 30, 2022 $ (2,880) Senior Secured Convertible Note Balance, January 1, 2022 $ — Issued in business combination 11,000 Valuation adjustment at business combination (1,146) Change in fair value (11) Balance, June 30, 2022 $ 9,843 Changes in fair value included in earnings for the period relating to liabilities held at June 30, 2022 $ (11) There were no transfers of financial liabilities between levels of the fair value hierarchy during the six months ended June 30, 2022. Other Fair Value Considerations – Carrying value of accounts receivables, contract assets, prepaid expenses and other assets, accounts payable and accrued expenses approximate fair value due to their short-term maturities and/or low credit risk.

Diluted net loss per share is computed by giving effect to all potential shares of common stock, including outstanding stock options and common stock issuable pursuant to Series B, A and Seed preferred stock possible conversion. Basic and diluted net loss per share was the same for each period presented, given that there are losses during the period, the inclusion of all potential common shares outstanding would have been anti-dilutive.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2022
Accounting Policies [Abstract]
Principles of Consolidation	The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Basis of Presentation	The financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
Foreign Currency	Foreign Currency We translate the financial statements of our foreign subsidiaries, which have a functional currency in the respective country’s local currency, to U.S. dollars using month-end exchange rates for assets and liabilities and actual exchange rates for revenue, costs and expenses on the date of the transaction. Translation gains and losses are included within “general and administrative expense” on the consolidated statements of operations. These gains and losses are immaterial to the financial statements.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and various other
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to concentration of credit risk consist principally of cash and cash equivalents and accounts receivable. We place our cash and cash equivalents with high credit-quality financial institutions. Such deposits may be in excess of federally insured limits. To date, we have not experienced any losses on our cash and cash equivalents. We perform periodic evaluations of the relative credit standing of the financial institutions. We perform ongoing credit evaluations of our customers’ financial condition and require no collateral from our customers. We maintain an allowance for doubtful accounts receivable based upon the expected collectability of accounts receivable balances.
Transaction Costs	Transaction Costs The Company incurred significant costs direct and incremental to the business combination and therefore to the recapitalization of the Company. We deferred such costs incurred in 2021. In 2022, upon closing of the business combination, total direct transaction costs were allocated between equity and liability instruments measured at fair value on a recurring basis that were newly issued in the recapitalization. Amounts allocated to equity were recorded to additional paid-in capital, while amounts allocated to the specified liabilities were recorded as other expense. See Note 8, Business Combination, to these consolidated financial statements for further information.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less, when acquired, to be cash equivalents. The Company maintains its cash with one commercial bank.
Effective Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Effective Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The amendments in this update modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. This update is effective beginning after December 15, 2021. We adopted this standard on January 1, 2022. The adoption of this standard did not have a material impact on our consolidated financial statements for the period ended June 30, 2022. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The ASU enhances and simplifies various aspects of the income tax accounting guidance in ASC 740, including requirements related to the following: (1) hybrid tax regimes; (2) tax basis step-up in goodwill obtained in a transaction that is not a business combination; (3) separate financial statements of entities not subject to tax; (4) intra-period tax allocation exception to the incremental approach; (5) ownership changes in investments; (6) interim-period accounting for enacted changes in tax law; and (7) year-to-date loss limitation in interim-period tax accounting. The amendments in ASU 2019-12 are effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods therein. This update is effective beginning after December 15, 2021. We adopted this standard on January 1, 2022. The adoption of this standard did not have a material impact on our consolidated financial statements for the period ended June 30, 2022. In January 2020, the FASB issued ASU 2020-01, Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 . The amendments in this update clarify certain interactions between the guidance to account for certain equity securities. This update is effective beginning after December 15, 2021. We adopted this standard on January 1, 2022. The adoption of this standard did not have a material impact on our consolidated financial statements for the period ended June 30, 2022. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity . Under ASU 2020-06, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives, or that do not result in substantial premiums accounted for as paid-in capital. The convertible debt instruments will now be accounted for as a single liability measured at amortized cost. This results in the interest expense recognized for convertible debt instruments to be closer to the coupon interest rate. The new guidance also requires the if-converted method to be applied for all convertible instruments when calculating earnings per share. This update is effective beginning after December 15, 2021. We adopted this standard on January 1, 2022. The adoption of this standard did not have a material impact on our consolidated financial statements for the period ended June 30, 2022. Recent Accounting Pronouncements Not Yet Adopted In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) . FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Certain qualitative and quantitative disclosures are required, as well as a retrospective recognition and measurement of impacted leases. In June 2020, FASB issued ASU 2020-05, Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Deferral of the Effective Dates for Certain Entities , which deferred the effective date of ASU 2016-02 to annual reporting periods beginning after December 15, 2021, with early adoption permitted. In July 2021, the FASB released Update No. 2021-05 Lessors—Certain Leases with Variable Lease Payments . The amendments in this update affect lessors with lease contracts that (1) have variable lease payments that do not depend on a reference index or a rate and (2) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing. The amendments in this update amend Topic 842. The amendments are effective for fiscal years beginning after December 15, 2021, for all entities, and interim periods within those fiscal years for public business entities and interim periods within fiscal years beginning after December 15, 2022, for all other entities. Management is currently evaluating the impact of adopting this standard on our financial condition and results of operations . In June 2016, FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , to revise the criteria for the measurement, recognition, and reporting of credit losses on financial instruments to be recognized when expected. In November 2019, FASB issued ASU 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) , which deferred the effective date of ASU 2016-13 to annual reporting periods beginning after December 15, 2022, with early adoption permitted. Management is currently evaluating the impact of adopting this standard on our financial condition and results of operations . In October 2021, the FASB issued ASU 2021-08 - Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customer s. The amendments in this update require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The amendments in this update should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendments is permitted, including adoption in an interim period. An entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. Management is currently evaluating the impact of adopting this standard on our financial condition and results of operations .
Fair Value Measurements	The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Valuation is based on unadjusted quoted prices in active markets for identical assets and liabilities that are accessible at the reporting date. Because valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2 : Valuation is determined from pricing inputs that are other than quoted prices in active markets that are either directly or indirectly observable as of the reporting date. Observable inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and interest rates and yield curves that are observable at commonly quoted intervals. Level 3 : Valuation is based on inputs that are both significant to the fair value measurement and unobservable. Level 3 inputs include situations where there is little, if any, market activity for the financial instrument. The inputs into the determination of fair value generally require significant management judgment or estimation. .
Net Loss Per Share	Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including outstanding stock options and common stock issuable pursuant to Series B, A and Seed preferred stock possible conversion. Basic and diluted net loss per share was the same for each period presented, given that there are losses during the period, the inclusion of all potential common shares outstanding would have been anti-dilutive.
