Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Description of Business and Summary of Significant Accounting Policies	Organization and Description of Business Outbrain Inc. (together with its subsidiaries, “Outbrain,” the “Company,” “we,” “our” or “us”), was incorporated in August 2006 in Delaware. The Company is headquartered in New York, New York and has wholly owned subsidiaries in Israel, Europe, Asia, Brazil and Australia. In connection with the Company’s initial public offering (“IPO”), its common stock began trading on The Nasdaq Stock Market LLC (“Nasdaq”) on July 23, 2021 under the “OB” ticker symbol. Outbrain is a leading technology platform that drives business results by connecting media owners and advertisers with engaged audiences to drive business outcomes across the Open Internet. The Company’s platform provides advertisements on media owners’ online properties. The Company generates revenue from advertisers through consumer engagements with advertisements that it delivers across a variety of third-party media owners’ online properties. The Company pays traffic acquisition costs to its media owner partners on whose digital properties the advertisements are shown. The Company’s advertiser solutions are mainly priced using a performance-based model based on the actual number of engagements generated by consumers, which is highly dependent on its ability to generate trustworthy and interesting advertisements to individual consumers based on its proprietary algorithms. A portion of the Company’s revenue is generated through advertisers participating in programmatic auctions wherein the pricing is determined by the auction results and not dependent on consumer engagement. Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and are unaudited. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission on March 8, 2024 (“2023 Form 10-K”). Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosures as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and judgments are based on historical information and on various other assumptions that the Company believes are reasonable under the circumstances. Estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to, the allowance for credit losses, sales allowance, software development costs eligible for capitalization, valuation of deferred tax assets, the useful lives of property and equipment, the useful lives and fair value of intangible assets, valuation of goodwill, the fair value of stock-based awards, and the recognition and measurement of income tax uncertainties and other contingencies. Actual results could differ materially from these estimates. Reclassifications Certain reclassifications have been made to the prior periods’ financial information in order to conform to the current period’s presentation. Certain Risks and Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, restricted cash, and accounts receivable. The Company’s cash and cash equivalents and restricted cash are generally invested in high-credit quality financial instruments with both banks and financial institutions to reduce the amount of exposure to any single financial institution. The Company generally does not require collateral to secure accounts receivable, with the exception of certain customers with higher potential credit risk who are required to prepay for their campaigns. No single advertiser accounted for 10% or more of the Company’s total revenue for the three and six months ended June 30, 2024 or 2023, or 10% or more of its gross accounts receivable balance as of June 30, 2024 and December 31, 2023. During the three and six months ended June 30, 2024 and 2023, none of the Company’s media owners accounted for 10% of its total traffic acquisition costs. Segment Information The Company has one operating and reporting segment. The Company’s chief operating decision maker is its Chief Executive Officer who makes resource allocation decisions and assesses performance based on financial information presented on a consolidated basis. New Accounting Pronouncements Under the JOBS Act, the Company meets the definition of an emerging growth company (“EGC”) and can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards would otherwise apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the Company is no longer an EGC or until the Company affirmatively and irrevocably opts out of the extended transition period. Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 requires enhanced disclosures about significant segment expenses and profitability measures for all public entities, including those that have one reportable segment. The ASU is required to be applied retrospectively and is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company’s financial instruments include restricted time deposits, severance pay fund deposits and foreign currency forward contracts. The Company determines the fair value of its financial instruments based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the Company uses the fair value hierarchy described below to distinguish between observable and unobservable inputs: Level I — Valuations based on quoted prices in active markets for identical assets and liabilities at the measurement date; Level II — Valuations based on quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be principally corroborated by observable market data for substantially the full term of the related assets or liabilities; and Level III — Valuations based on unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or no market data. The following table sets forth the fair value of the Company’s financial assets and liabilities measured on a recurring basis by level within the fair value hierarchy: June 30, 2024 Level I Level II Level III Total (In thousands) Financial Assets: Cash equivalents and investments (1) $ 22,138 $ 159,771 $ — $ 181,909 Restricted time deposit (2) — 599 — 599 Severance pay fund deposits (2) — 4,834 — 4,834 Foreign currency forward contract (3) — 115 — 115 Total financial assets $ 22,138 $ 165,319 $ — $ 187,457 Financial Liabilities: Foreign currency forward contract (4) — 467 — 467 Total financial liabilities $ — $ 467 $ — $ 467 December 31, 2023 Level I Level II Level III Total (In thousands) Financial Assets: Cash equivalents and investments (1) $ 15,355 $ 163,577 $ — $ 178,932 Restricted time deposit (2) — 190 — 190 Severance pay fund deposits (2) — 4,901 — 4,901 Foreign currency forward contract (3) — 1,254 — 1,254 Total financial assets $ 15,355 $ 169,922 $ — $ 185,277 Financial Liabilities: Foreign currency forward contract (4) — 106 — 106 Total financial liabilities $ — $ 106 $ — $ 106 _____________________ (1) Money market securities are valued using Level I of the fair value hierarchy, while the fair values of U.S. Treasuries, government bonds, commercial paper, and corporate bonds are considered Level II and are obtained from independent pricing services, which may use various methods, including quoted prices for identical or similar securities in active and inactive markets. See Note 4 for additional detail of the Company’s fixed income securities by balance sheet location. (2) Recorded within other assets. (3) Recorded within prepaid expenses and other current assets. (4) Recorded within accrued and other current liabilities. The Company records the fair values of the assets and liabilities relating to its undesignated foreign currency forward contracts on a gross basis in its condensed consolidated balance sheets, as they are not subject to master netting arrangements. There is no cash collateral required to be pledged by the Company or its counterparties. The Company enters into foreign currency forward exchange contracts to manage the effects of fluctuations in foreign currency exchange rates on its net cash flows from non-U.S. dollar denominated operations. By entering into foreign currency forward contracts, the Company is exposed to a potential credit risk that the counterparty to its contracts will fail to meet its contractual obligations. If a counterparty fails to perform, the Company’s maximum credit risk exposure would be the positive fair value of the foreign currency forward contracts, or any asset balance, which represents the amount the counterparty owes to the Company. In order to mitigate the counterparty risk, the Company performs an evaluation of its counterparty credit worthiness, and its forward contracts have a term of no more than 18 months. During the three and six months ended June 30, 2024, the Company recognized net losses of $0.6 million and $1.5 million, respectively, within interest income and other income, net in its condensed consolidated statements of operations, related to mark-to-market adjustments on its undesignated foreign currency forward contacts. The Company recorded corresponding net losses of $0.1 million and $0.2 million, respectively, for the three and six months ended June 30, 2023. The Convertible Notes are recorded within long-term debt on the Company’s condensed consolidated balance sheets at their carrying value, which may differ from their fair value. The fair value of Convertible Notes is estimated using external pricing data, including any available market data for other debt instruments with similar characteristics. The following table summarizes the carrying value and the estimated fair value of the Convertible Notes, based on Level II measurements of the fair value hierarchy: June 30, 2024 December 31, 2023 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value (In thousands) Convertible Notes $ 118,000 $ 98,341 $ 118,000 $ 95,958 See Note 9 for additional information relating to the Convertible Notes.

The Convertible Notes mature on July 27, 2026, unless earlier converted, redeemed, or repurchased. On April 14, 2023, the Company repurchased $118.0 million aggregate principal amount of the Convertible Notes out of the initially issued principal balance of $236.0 million via a privately negotiated repurchase agreement with Baupost Group Securities, L.L.C., the sole holder of the Convertible Notes, for approximately $96.2 million in cash, including accrued interest, representing a discount of approximately 19% to the principal amount of the repurchased notes. As a result, the Company recorded a pre-tax gain of approximately $22.6 million within g ain on convertible debt in the Company’s consolidated statement of operations for the three and six months ended June 30, 2023. Following the closing of the repurchase, the repurchased notes were cancelled by the Trustee, and $118.0 million principal amount of the Convertible Notes out of the initially issued principal balance of $236.0 million, remains outstanding as of June 30, 2024 and continues to be subject to the terms of the Indenture pursuant to which they were issued. Interest on the Convertible Notes is payable semi-annually in arrears on January 27 and July 27 of each year, beginning on January 27, 2022, at a rate of 2.95% per year. The initial conversion rate for the Convertible Notes is 40 shares of the Company’s common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of $25 per share of the Company’s common stock), subject to adjustment. See No te 9 to th e Company’s 2023 Annual Report on Form 10-K for additional information relating to the Company’s Convertible Notes, including the redemption and conversion provisions. Revolving Credit Facility The Company’s First Amendment to the Second Amended and Restated Loan and Security Agreement with Silicon Valley Bank, a division of First Citizens Bank & Trust Company, provides, subject to borrowing availability and certain other conditions, for revolving loans in an aggregate principal amount of up to $75.0 million (the “Facility”), with a $15.0 million sub-facility for letters of credit. The Company’s borrowing availability under the Facility is calculated by reference to a borrowing base which is determined by specified percentages of eligible accounts receivable. The Facility will terminate on the earlier of (i) November 2, 2026 or (ii) 120 days prior to the maturity date of the Convertible Notes, unless all of the Convertible Notes have been converted to common equity securities of the Company. Outstanding loans under the Facility, as recently amended, accrue interest, at the Company’s option based upon borrowing availability under the Facility, at a rate equal to either (a) a base rate minus an applicable margin ranging from 1.5% to 1.0% per annum or (b) SOFR plus an applicable margin of 1.5% to 2.0% per annum, subject to a SOFR adjustment ranging from 0.10% to 0.15%, depending on the length of the borrowing. The undrawn portions of the commitments under the Facility are subject to a commitment fee at a rate ranging from 0.20% per annum to 0.30% per annum, based upon borrowing availability under the Facility. The Facility contains representations and warranties, including, without limitation, with respect to collateral; accounts receivable; financials; litigation, indictment and compliance with laws; disclosure and no material adverse effect, each of which is a condition to funding. Additionally, the Facility includes events of default and customary affirmative and negative covenants applicable to the Company and its subsidiaries, including, without limitation, restrictions on liens, indebtedness, investments, fundamental changes, dispositions, restricted payments and prepayment of the Convertible Notes and of junior indebtedness. The Facility contains a financial covenant that requires, in the event that credit extensions under the Facility equal or exceed 85% of the available commitments under the Facility or upon the occurrence of an event of default, the Company to maintain a minimum consolidated monthly fixed charge coverage ratio of 1.00. The obligations of the Company, and the other subsidiary co-borrowers under the 2021 Revolving Credit Facility are secured by a first-priority lien on substantially all the assets of the Company and such other subsidiary co-borrowers. The Company was in compliance with all of the related financial covenants as of June 30, 2024 and December 31, 2023.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Share Repurchases On December 14, 2022, the Company’s Board of Directors (the “Board”) approved a new share repurchase program, authorizing the Company to repurchase up to $30 million of its common stock, par value $0.001 per share, with no requirement to purchase any minimum number of shares. The manner, timing, and actual number of shares repurchased under the program will depend on a variety of factors, including price, general business and market conditions, and other investment opportunities. Shares may be repurchased through privately negotiated transactions or open market purchases, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. The repurchase program may be commenced, suspended, or terminated at any time by the Company at its discretion without prior notice. The following is a summary of the Company’s share repurchase activity under its share repurchase program for the three and six months ended June 30, 2024 and 2023: Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 (In thousands, except share information) Shares repurchased 464,054 200,000 1,410,001 1,513,073 Fair value of shares repurchased $ 2,000 $ 988 $ 5,862 $ 7,130 As of June 30, 2024, the remaining availability under the Company’s $30 million share repurchase program was $6.6 million. Commission costs associated with share repurchases and excise taxes accrued as a result of the Inflation Reduction Act of 2022 do not reduce the remaining authorized amount under the repurchase programs. In addition, the Company may periodically withhold shares to satisfy employee tax withholding obligations arising in connection with the vesting of restricted stock units and exercise of options and warrants in accordance with the terms of the Company’s equity incentive plans and the underlying award agreements. During the three and six months ended June 30, 2024, the Company withheld 47,088 and 84,580 shares, respectively, with a fair value of $0.2 million and $0.4 million , respectively, to satisfy the employee tax withholding obligations. For the three and six months ended June 30, 2023, the Company withheld 42,065 shares and 90,267 shares, respectively, with a fair value of $0.2 million and $0.4 million , respectively. The following table details the changes in accumulated other compressive loss, net of tax: Foreign Currency Translation Loss Unrealized Loss on Investments in Marketable Securities Total Accumulated Other Comprehensive Loss (In thousands) Balance–December 31, 2023 $ (9,039) $ (13) $ (9,052) Other comprehensive loss, net of tax (1,045) (310) (1,355) Balance–June 30, 2024 $ (10,084) $ (323) $ (10,407) There were no amounts reclassified from AOCI to earnings during the three and six months ended June 30, 2024. During the three months ended June 30, 2023, $0.4 million of realized losses on investments in marketable securities, net of taxes of $0.1 million, were released from accumulated other comprehensive loss to earnings, and recorded within interest income and other income, net in the Company’s condensed consolidated statements of operations for the

Share-Based Payment Arrangement [Abstract]
Stock-based Compensation	Equity Incentive Plans In July 2021, the Board and the Company’s stockholders approved the 2021 Long-Term Incentive Plan (the “2021 Plan”), which may be used to grant, among other award types, stock options, restricted stock units (“RSUs”) and performance stock units (“PSUs”). The number of shares of common stock reserved for future issuance under the 2021 Plan will be increased pursuant to provisions for annual automatic evergreen increases. The Company’s previous awards issued under its 2007 Omnibus Securities and Incentive Plan, as amended and restated on January 21, 2009 (the “2007 Plan”), remain subject to the 2007 Plan. As of June 30, 2024, 5,277,000 and 899,922 sha res were available for grant under the 2021 Plan and the 2007 Plan, respectively. The Company generally issues new shares for stock option exercises and vesting of RSUs. The Company recognizes stock-based compensation expense for stock-based awards based on the estimated fair value of the awards, as further described below, and accounts for forfeitures as they occur. The following table summarizes stock-based compensation expense recognized in the Company’s condensed consolidated statements of operations for the periods presented: Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 (In thousands) Research and development $ 993 $ 1,037 $ 1,706 $ 1,539 Sales and marketing 1,703 1,222 2,770 2,248 General and administrative 1,812 1,237 2,959 2,320 Total stock-based compensation $ 4,508 $ 3,496 $ 7,435 $ 6,107 As of June 30, 2024, the Company’s remaining unrecognized stock-based compensation expense was $0.4 million for unvested stock options, $26.0 million for unvested RSUs and $3.3 million for unvested PSUs. The following table summarizes stock option, RSU and PSU activity for the six months ended June 30, 2024: Stock Options (1) RSUs PSUs Outstanding—December 31, 2023 2,409,553 3,417,083 90,000 Granted — 2,560,218 1,136,600 Exercised/Vested — (983,414) — Forfeited (112,371) (207,337) — Outstanding—June 30, 2024 2,297,182 4,786,550 1,226,600 ____________________ (1) Includes 2,861 stock appreciation rights (SARs), which are accounted for as liability awards, and expire in September 2024. Stock Options The Company estimates the fair value of its stock option awards on the grant date using the Black-Scholes option pricing model. There were no stock options granted during the six months ended June 30, 2024. Service-based Restricted Stock Units The Company grants service-based RSUs to its employees and non-employee directors, which generally vest over a period of three to four years. The fair values of service-based RSUs are based on the fair value of the Company's common stock on the date of grant. During the six months ended June 30, 2024, the Company granted 2,560,218 service-based RSUs with a weighted average grant date fair value of $4.52 per share. Performance Stock Units The Company’s PSUs granted in 2023 vest over a period of three years, subject to the employee’s continued employment through the vesting date and satisfaction of certain pre-established performance targets based on Company financial metrics. Expense related to these PSUs is recognized ratably during the 3-year performance period, based on the probability of attaining the performance targets. The potential number of shares that may be earned is determined based on achievement of performance targets up to a maximum of 100% of the number of PSUs granted. In June 2024, the Company granted market-based PSU awards to its senior executives, which are earned subject to achievement of specified stock price hurdles for 20 days out of a 30-trading day window during the 3-year performance period, as well as continued employment through the quarterly vesting dates over the 3-year period. The number of shares that are eligible to vest range from 0% to 100% of the number of PSUs granted based on achievement of the specified stock price hurdles, with half of our CEO’s PSU award subject to vesting based on two additional above-target stock price hurdles. The Company uses a Monte Carlo simulation, which uses subjective assumptions and simulates multiple stock price paths of the Company's common stock to determine the fair value of market-based PSUs on the date of grant. Compensation expense is recognized using an accelerated attribution method over the greater of the derived service periods and explicit quarterly service periods. Compensation expense, net of forfeitures, is recorded regardless of whether the market condition will be ultimately satisfied. The following assumptions are used to estimate the fair value of the Company’s market-based PSUs: Six Months Ended June 30, 2024 Weighted average grant date fair value $ 2.86 Expected volatility 60.68 % Risk-free rate 4.53 % Expected dividend yield — Stock-Based Awards Granted Outside of Equity Incentive Plans Warrants The Company issued equity-classified warrants to purchase shares of common stock to certain third-party advisors, consultants, and financial institutions, which expire between November 2024 and September 2026. As of June 30, 2024 and December 31, 2023, 188,235 warrants were outstanding and exercisable with a weighted average exercise price of $7.57. Employee Stock Purchase Plan As of June 30, 2024, approximately 2,849,545 shares of the Company’s common stock have been reserved for issuance under the Company’s 2021 Employee Stock Purchase Plan (the “ESPP”), which is subject to annual automatic evergreen increases. There have been no shares purchased under the ESPP as it is not yet active. See Note 13 to th e Company’s 2023 Annual Report on Form 10-K for additional information relating to the Company’s share-based compensation awards.

Subsequent Events [Abstract]
Subsequent Events	On August 1, 2024, the Company entered into a definitive share purchase agreement (the “Agreement”) with Altice Teads S.A. (the “Seller” or “Altice”), a public limited liability company (société anonyme) incorporated and existing under the laws of the Grand Duchy of Luxembourg and the sole shareholder of Teads S.A., a public limited liability company (société anonyme) incorporated and existing under the laws of the Grand Duchy of Luxembourg (“Teads”), and Teads. Pursuant to the Agreement, Outbrain agreed to acquire all of the issued and outstanding share capital of Teads upon the terms and subject to the conditions set forth in the Agreement (the “Transaction”). The Agreement provides for the following consideration to be paid to the Seller at closing of the Transaction (the “Closing”): (1) a cash payment of $725.0 million, subject to certain customary adjustments as set forth in the Agreement (the “Cash Consideration”), (2) $35.0 million newly issued shares of the Company’s common stock, par value $0.001 (the “Common Stock”; such newly issued shares of Common Stock, the “Consideration Common Stock”), and (3) $10.5 million newly issued shares of the Company’s Series A Convertible Preferred Stock, par value $0.001 (the “Series A Preferred Stock” and, together with the Consideration Common Stock, the “Consideration Stock”). Additionally, the Seller will be entitled to a deferred cash payment in an amount equal to $25.0 million payable in one or more installments subject to compliance with the covenants of any of the debt financing(s) described below. Following the Closing, the Seller will own approximately 42% of the Company’s issued and outstanding shares of Common Stock, or 48% assuming conversion of the Series A Preferred Stock (based on the amount of issued and outstanding shares of Common Stock as of June 30, 2024). Subject to certain conditions, either the Company or the Seller may terminate the Agreement if the Closing has not occurred by the date which is nine months after the date of the Agreement, which date may be extended for three additional periods of three months each if the reason for not closing is that the regulatory conditions have not been satisfied. The Agreement contains customary representations, warranties and covenants for a transaction of this type. Closing under the Agreement is subject to customary conditions, including (1) approval of the Company’s stockholders to the issuance of the Consideration Stock in accordance with the rules and regulations of the Nasdaq Stock Market and the Company’s organizational documents (the “Stockholder Approval”), (2) the absence of any law or order issued by any governmental authority prohibiting or preventing the consummation of the Transaction, (3) obtaining certain regulatory approvals, including the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (4) subject to certain exceptions, the accuracy of the representations and warranties of, and compliance with covenants by, each of the parties to the Agreement, and (5) the absence of a Material Adverse Event (as defined in the Agreement). Pursuant to the Agreement, the Company will file a certificate of designation (the “Certificate of Designation”) with the Delaware Secretary of the State at Closing designating the rights, preferences and limitations of the shares of the Series A Preferred Stock. The Series A Preferred Stock will have a liquidation preference (the “Liquidation Preference”) of $10.00 per share (adjusted in the event of a stock dividend, stock split, stock distribution, recapitalization or combination with respect to the Series A Preferred Stock). Upon the occurrence of a Liquidation Event (as defined in the Certificate of Designation), the holders of the Series A Preferred Stock shall be entitled to the greater of (i) the Liquidation Preference plus the aggregate amount of all accrued and accumulated dividends on the Series A Preferred Stock and (ii) the consideration that a holder of Series A Preferred Stock would have received if it had converted its stock into Common Stock immediately prior to the Liquidation Event. Dividends on the Series A Preferred Stock will accrue on a quarterly basis at a rate of 10% per annum, payable in cash or payment-in-kind at Outbrain’s option. The holders of the Series A Preferred Stock shall have the right to convert all or a portion of the holder’s Series A Preferred Stock to a number of shares of Common Stock determined as the current Liquidation Preference of such Series A Preferred Stock to be converted plus an amount equal to the sum of all accrued and unpaid dividends for the then-current dividend period, divided by the conversion price of $10.00 per share, as may be subject to customary adjustments in accordance with the Certificate of Designation. The Company may elect to convert all or a portion of the Series A Preferred Stock that is at least 10% of the then outstanding Series A Preferred Stock to Common Stock after two years subject to the Common Stock achieving a certain price threshold. The Series A Preferred Stock may be redeemed by the Company in whole or part in cash prior to the five-year anniversary of its issuance, subject to payment of certain premiums, and after the fifth anniversary of issuance without premium. The Series A Preferred Stock will vote together with the Common Stock on an as-converted basis on all matters, and not as a separate class. The Agreement provides that the Company and Seller will enter into a stockholders agreement (the “Stockholders Agreement”) at Closing. Pursuant to the Stockholders Agreement, the number of directors on the Company Board shall be increased by two, and the Seller shall have the right to nominate for election to the Company Board two persons, one of whom shall be non-affiliated with the Seller and must qualify as an independent director pursuant to the requirements of the Nasdaq Stock Market. The Seller shall have the right to nominate (1) two directors until the Seller and its affiliated stockholders cease to hold in the aggregate at least 25% of the total voting power of the outstanding capital stock of the Company and (2) one director until the Seller and its affiliated stockholders cease to hold in the aggregate at least 10% of the total voting power of the outstanding capital stock of the Company, in each case on an as-converted basis. Additionally, commencing on the third anniversary of the Closing, Seller shall have the right to nominate three directors until such time as the Seller and its affiliated stockholders cease to own at least 30% of the total voting power of the outstanding capital stock of the Company, on an as-converted basis. The Stockholders Agreement also requires that until such time that the Seller and its affiliated stockholders hold in the aggregate less than 15% of the total voting power of the outstanding capital stock of the Company (the “15% Threshold”), on an as-converted basis, the Seller will take such action necessary to cause its affiliate stockholders to vote their shares at each meeting of the Company’s stockholders in the same manner as recommended by the Company Board. The Stockholders Agreement further provides that until such time that Seller and its affiliated stockholders hold less than the 15% Threshold in the aggregate, they will comply with customary standstill restrictions with respect to the Company. The Stockholders Agreement will include restrictions on the transferability of the Consideration Stock. Under the Agreement, the Company and Seller will also enter into a registration rights agreement (the “Registration Rights Agreement”) at Closing, pursuant to which the Company will provide customary demand and piggyback registration rights to the holders of the Registrable Shares (as defined in the Registration Rights Agreement), which includes the Consideration Common Stock. In connection with the execution of the Agreement, each of Viola Ventures III, L.P. and Yaron Galai (together, the “Company Stockholders”) in their respective capacities as stockholders of the Company, entered into a customary Stockholder Support Agreement (the “Support Agreement”) with the Company and Seller, pursuant to which the Company Stockholders agreed, among other things, to vote their respective shares of Common Stock in favor of the Stockholder Approval and any other proposals brought to a vote of stockholders of the Company in furtherance of the Transaction. Notwithstanding the foregoing, the Company Stockholders are permitted to take any action and participate in any discussions or negotiations regarding a Qualifying Purchaser Acquisition Proposal (as defined in the Agreement) to the same extent that the Company is permitted to pursuant to the Agreement. As of June 30, 2024, the Company Stockholders beneficially own an aggregate of approximately 20.13% of the Company’s issued and outstanding shares of Common Stock. In connection with entering into the Agreement, the Company entered into a debt commitment letter, dated August 1, 2024 (the “Commitment Letter”), with Goldman Sachs Bank USA, Jefferies Finance LLC and Mizuho Bank, LTD (collectively, the “Commitment Parties”), pursuant to which the Commitment Parties have committed to provide (i) a $100 million senior secured revolving credit facility (the “Revolving Credit Facility”) and (ii) a senior secured bridge facility in an aggregate principal amount of up to $750 million (the “Bridge Facility”). The Bridge Facility will be used to fund the cash consideration for the Transaction and to pay fees and expenses related thereto. Additionally, a portion of the Revolving Credit Facility may be used to fund a portion of the cash consideration for the Transaction and to pay fees and expenses related thereto, and will otherwise be available, for working capital and general corporate purposes. The obligation of Commitment Parties to provide the contemplated financings is subject to a number of customary conditions contained in the Commitment Letter, including the execution of definitive debt financing documentation contemplated by the Commitment Letter and the Transaction being consummated substantially contemporaneously with the initial funding of the Bridge Facility. The Company expects to replace the Bridge Facility with permanent financing, which the Company currently expects to include the issuance of debt securities.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and are unaudited. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission on March 8, 2024 (“2023 Form 10-K”).
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosures as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and judgments are based on historical information and on various other assumptions that the Company believes are reasonable under the circumstances. Estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to, the allowance for credit losses, sales allowance, software development costs eligible for capitalization, valuation of deferred tax assets, the useful lives of property and equipment, the useful lives and fair value of intangible assets, valuation of goodwill, the fair value of stock-based awards, and the recognition and measurement of income tax uncertainties and other contingencies. Actual results could differ materially from these estimates.
Reclassifications	Reclassifications Certain reclassifications have been made to the prior periods’ financial information in order to conform to the current period’s presentation.
Certain Risks and Concentrations	Certain Risks and Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, restricted cash, and accounts receivable. The Company’s cash and cash equivalents and restricted cash are generally invested in high-credit quality financial instruments with both banks and financial institutions to reduce the amount of exposure to any single financial institution.
Segment Information	Segment Information The Company has one operating and reporting segment. The Company’s chief operating decision maker is its Chief Executive Officer who makes resource allocation decisions and assesses performance based on financial information presented on a consolidated basis.
New Accounting Pronouncements And Recently Issued Accounting Pronouncements	New Accounting Pronouncements Under the JOBS Act, the Company meets the definition of an emerging growth company (“EGC”) and can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards would otherwise apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the Company is no longer an EGC or until the Company affirmatively and irrevocably opts out of the extended transition period. Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 requires enhanced disclosures about significant segment expenses and profitability measures for all public entities, including those that have one reportable segment. The ASU is required to be applied retrospectively and is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is in the process of evaluating the impact of ASU 2023-07 on its segment disclosures. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 is focused on increased visibility into specific income tax components, requiring disclosures of specific categories and a greater disaggregation of information by jurisdiction within the effective tax rate reconciliation and income taxes paid disclosures. ASU 2023-09 is effective for our annual periods beginning January 1, 2025, with early adoption permitted. The Company is in the process of evaluating the impact of ASU 2023-09 on its tax-related disclosures.
Fair Value Measurement	The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company’s financial instruments include restricted time deposits, severance pay fund deposits and foreign currency forward contracts. The Company determines the fair value of its financial instruments based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the Company uses the fair value hierarchy described below to distinguish between observable and unobservable inputs: Level I — Valuations based on quoted prices in active markets for identical assets and liabilities at the measurement date; Level II — Valuations based on quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be principally corroborated by observable market data for substantially the full term of the related assets or liabilities; and Level III
Derivative Financial Instruments	The Company records the fair values of the assets and liabilities relating to its undesignated foreign currency forward contracts on a gross basis in its condensed consolidated balance sheets, as they are not subject to master netting arrangements. There is no cash collateral required to be pledged by the Company or its counterparties. The Company enters into foreign currency forward exchange contracts to manage the effects of fluctuations in foreign currency exchange rates on its net cash flows from non-U.S. dollar denominated operations.
Share-Based Payment Arrangement	Stock Options The Company estimates the fair value of its stock option awards on the grant date using the Black-Scholes option pricing model. There were no stock options granted during the six months ended June 30, 2024. Service-based Restricted Stock Units The Company grants service-based RSUs to its employees and non-employee directors, which generally vest over a period of three to four years. The fair values of service-based RSUs are based on the fair value of the Company's common stock on the date of grant. During the six months ended June 30, 2024, the Company granted 2,560,218 service-based RSUs with a weighted average grant date fair value of $4.52 per share. Performance Stock Units The Company’s PSUs granted in 2023 vest over a period of three years, subject to the employee’s continued employment through the vesting date and satisfaction of certain pre-established performance targets based on Company financial metrics. Expense related to these PSUs is recognized ratably during the 3-year performance period, based on the probability of attaining the performance targets. The potential number of shares that may be earned is determined based on achievement of performance targets up to a maximum of 100% of the number of PSUs granted. In June 2024, the Company granted market-based PSU awards to its senior executives, which are earned subject to achievement of specified stock price hurdles for 20 days out of a 30-trading day window during the 3-year performance period, as well as continued employment through the quarterly vesting dates over the 3-year period. The number of shares that are eligible to vest range from 0% to 100% of the number of PSUs granted based on achievement of the specified stock price hurdles, with half of our CEO’s PSU award subject to vesting based on two additional above-target stock price hurdles. The Company uses a Monte Carlo simulation, which uses subjective assumptions and simulates multiple stock price paths of the Company's common stock to determine the fair value of market-based PSUs on the date of grant. Compensation expense is recognized using an accelerated attribution method over the greater of the derived service periods and explicit quarterly service periods. Compensation expense, net of forfeitures, is recorded regardless of whether the market condition will be ultimately satisfied. The following assumptions are used to estimate the fair value of the Company’s market-based PSUs: Six Months Ended June 30, 2024 Weighted average grant date fair value $ 2.86 Expected volatility 60.68 % Risk-free rate 4.53 % Expected dividend yield —
