Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Presentation	Overview and Basis of Presentation Description of Business Semrush Holdings, Inc. (“Semrush Holdings”) and its subsidiaries (together the “Company”, or “Semrush”) provide an online visibility management software-as-a-service (“SaaS”) platform. The Company’s platform enables its subscribers to improve their online visibility and drive traffic, including on their websites and social media pages, and distribute highly relevant content to their customers on a targeted basis across various channels to drive high-quality traffic and measure the effectiveness of their digital marketing campaigns. The Company is headquartered in Boston, Massachusetts, and has wholly owned subsidiaries in the United States, Spain, the Czech Republic, the Netherlands, Cyprus, Serbia, Poland, Germany, Armenia, Canada, and France. The Company is subject to a number of risks and uncertainties common to companies in similar industries and stages of development that could affect future operations and financial performance. These risks include, but are not limited to, rapid technological change, competitive pressure from substitute products or larger companies, protection of proprietary technology, management of international activities, the need to obtain additional financing to support growth, and dependence on third parties and key individuals. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The unaudited condensed consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements as of and for the year ended December 31, 2023, and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of March 31, 2024, and for the three months ended March 31, 2024 and 2023. The consolidated balance sheet as of December 31, 2023 included herein was derived from the audited consolidated financial statements as of that date. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, any other interim periods, or any future year or period. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 7, 2024. The accompanying unaudited condensed consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the unaudited condensed consolidated financial statements. As of March 31, 2024, there have been no material changes in the Company's significant accounting policies from those that were disclosed in the Annual Report on Form 10-K, except as discussed below.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and subsidiaries in which it holds a controlling interest. All intercompany transactions and balances have been eliminated in consolidation. Ownership interests in subsidiaries represented by other parties that do not control the entity are presented in the consolidated financial statements as activities and balances attributable to noncontrolling interests. 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, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these unaudited condensed consolidated financial statements include, but are not limited to, revenue recognition, expected future cash flows used to evaluate the recoverability of long-lived assets, contingent liabilities, expensing and capitalization of research and development costs for internal-use software, the average period of benefit associated with costs capitalized to obtain revenue contracts, the determination of the fair value of stock-based awards issued, stock-based compensation expense, the determination of the estimated fair value of loan receivables and convertible notes held by the Company, the valuations of the intangible assets acquired through acquisitions, the estimation of the Company’s incremental borrowing rate, and the recoverability of the Company’s net deferred tax assets and related valuation allowance. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. Subsequent Events Considerations The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the unaudited condensed consolidated financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. See Note 19 for additional information regarding the Company’s subsequent events. Emerging Growth Company Status The Company is an "emerging growth company" (“EGC”), as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”), and may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not "emerging growth companies." The Company may take advantage of these exemptions until the Company is no longer an "emerging growth company." Section 107 of the JOBS Act provides that an "emerging growth company" can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company has elected to use the extended transition period for complying with new or revised accounting standards and, as a result of this election, its condensed consolidated financial statements may not be comparable to companies that comply with public company effective dates. The Company may take advantage of these exemptions up until the last day of the year following the fifth anniversary of an offering or such earlier time that it is no longer an emerging growth company. The Company would cease to be an emerging growth company if it has more than $1.07 billion in annual revenue, has more than $700.0 million in market value of its stock held by non-affiliates, or it issues more than $1.0 billion of non-convertible debt securities over a three-year period. Revenue Recognition The Company primarily derives revenue from subscriptions to the Company’s SaaS services and related customer support. For the three months ended March 31, 2024 and 2023, subscription revenue accounted for nearly all of the Company’s revenue. Revenue related to other revenue was not material for the three months ended March 31, 2024 and 2023. The Company offers subscriptions to its platform primarily on a monthly or annual basis. The Company sells its products and services primarily through a self-service model and also directly through its sales force. The Company’s subscription arrangements provide customers the right to access the Company’s hosted software applications. Customers do not have the right to take possession of the Company’s software during the hosting arrangement. Subscriptions are generally non-cancellable during the contractual subscription term; however, subscription contracts contain a right to a refund if requested within seven days of purchase. The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration it expects to receive in exchange for those products or services. There were no changes to the Company’s revenue recognition policies since the filing of its Annual Report on Form 10-K with the SEC on March 7, 2024. Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. The Company primarily invoices and collects payments from customers for its services in advance on a monthly or annual basis. Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as deferred revenue, and the remaining portion is recorded as deferred revenue, net of current portion. Deferred revenue increased by $5,650 as of March 31, 2024 compared to December 31, 2023. During the three months ended March 31, 2024 and 2023, $30,351 and $25,513 of revenue was recognized that was included in deferred revenue as of December 31, 2023 and 2022, respectively. The Company has elected to exclude amounts charged to customers for sales tax from the transaction price. Accordingly, revenue is presented net of any sales tax collected from customers. Transaction Price Allocated to Future Performance Obligations ASC 606 requires that the Company disclose the aggregate amount of the transaction price that is allocated to performance obligations that have not yet been satisfied as of the balance sheet dates reported. For contracts with an original expected duration greater than one year, the aggregate amount of the transaction price allocated to the performance obligations that were unsatisfied as of March 31, 2024 was $1,386, of which the Company expects to recognize $1,080 over the next 12 months. For contracts with an original expected duration of one year or less, the Company has applied the practical expedient available under ASC 606 to not disclose the amount of transaction price allocated to unsatisfied performance obligations as of March 31, 2024. For performance obligations not satisfied as of March 31, 2024, and to which this expedient applies, the nature of the performance obligations is consistent with performance obligations satisfied as of December 31, 2023. Costs to Obtain a Contract The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and recorded as deferred contract costs in the unaudited condensed consolidated balance sheets and are amortized over a period of approximately 24 months on a systematic basis, consistent with the pattern of transfer of the goods or services to which the asset relates. The 24-month period represents the estimated benefit period of the customer relationship and has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period based on historical experience and future expectations. Deferred contract costs that will be recorded as expense during the succeeding 12-month period are recorded as deferred contract costs, current portion, and the remaining portion is recorded as deferred contract costs, net of current portion. Amortization of deferred contract costs is included in sales and marketing expense in the accompanying unaudited condensed consolidated statements of operations and comprehensive income (loss). Concentrations of Credit Risk and Significant Customers The Company has no off-balance sheet risk, such as foreign exchange contracts, option contracts, or other hedging arrangements. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company's accounts receivable. Credit risk with respect to accounts receivable is dispersed due to the large number of customers of the Company. The Company routinely assesses the creditworthiness of its customers and generally does not require its customers to provide collateral or other security to support accounts receivable. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company's accounts receivable. As of March 31, 2024 and December 31, 2023, no individual customer represented more than 10% of the Company’s accounts receivable. During the three months ended March 31, 2024 and 2023, no individual customer represented more than 10% of the Company’s revenue. Disclosure of Fair Value of Financial Instruments The Company’s financial instruments include cash, cash equivalents, investments, accounts receivable, loan receivables, accounts payable, and accrued expenses. The Company’s investments are classified as available-for-sale and reported at fair value in accordance with the market approach utilizing quoted prices that were directly or indirectly observable. The Company has elected the fair value option in respect to the accounting for its loan receivable investment, resulting in increases and decreases in the fair value of such investments being recorded to other income, net for each reporting period. The carrying amount of the remainder of the Company’s financial instruments approximated their fair values as of March 31, 2024 and December 31, 2023, due to the short-term nature of these instruments. The Company has evaluated the estimated fair value of financial instruments using available market information. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. See below for further discussion. Foreign Currency Translation The Company operates in a multi-currency environment having transactions in such currencies as the U.S. dollar, zloty, Czech koruna, euro, and others. The reporting currency of the Company is the U.S. dollar. The foreign currency exchange gain (loss) included in other income, net for the three months ended March 31, 2024 and 2023 was $445 and $(638), respectively. Comprehensive income (loss) Comprehensive income (loss) is comprised of two components: net income (loss) and other comprehensive income (loss), which includes other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. For the three months ended March 31, 2024 and 2023 , comprehensive income (loss) consists of net income (loss), the change in the cumulative foreign currency translation adjustment, and unrealized loss on investments. The tax effect of the cumulative foreign currency translation adjustment and unrealized loss on investments was not significant for the three months ended March 31, 2024 and 2023 . Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”) . ASU 2023-07 expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of adopting ASU 2023-07 on its consolidated financial statements and 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 requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, ASU 2023-09 requires certain disclosures of state versus federal income tax expense and taxes paid. The amendments in ASU 2023-09 are required to be adopted for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied on a prospective basis although retrospective application is permitted. The Company is evaluating the impact of adopting ASU 2023-09 on its consolidated financial statements and disclosures.

Cash and Cash Equivalents [Abstract]
Cash, Cash Equivalents, Restricted Cash, and Investments	Cash, Cash Equivalents, Restricted Cash, and Investments The Company considers all highly liquid instruments purchased with an original maturity date of 90 days or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of cash on deposit with banks and amounts held in interest-bearing money market funds. Cash equivalents are carried at cost, which approximates their fair market value. Short‑term investments consist of investments with original maturities greater than 90 days, as of the date of purchase. The Company considers its investment portfolio available-for-sale. The Company adjusts the cost of investments for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion in interest income in the unaudited condensed consolidated statements of operations. When the Company holds debt investments classified as available-for-sale pursuant to ASC 320, Investments — Debt Securities , it records available-for-sale securities at fair value, with unrealized gains and losses included in accumulated other comprehensive loss in stockholders’ equity. The Company has classified its investments with maturities beyond one year as short term, based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The Company includes interest and dividends on securities classified as available-for-sale in interest income in the unaudited condensed consolidated statements of operations and comprehensive income (loss). Realized gains and losses are recorded in the unaudited condensed consolidated statements of operations and comprehensive income (loss) based on the specific-identification method. There was no material realized gains or losses on investments for the three months ended March 31, 2024 or 2023. As of March 31, 2024 and December 31, 2023, the aggregate fair value of investments held by the Company in an unrealized loss position for less than twelve months was $143,186 and $89,381, respectively. As of March 31, 2024, the aggregate fair value of investments held by the Company in a continuous unrealized loss position for greater than twelve months was $43,850. The Company did not hold any investments in an unrealized loss position for greater than twelve months as of December 31, 2023. On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) and ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815 Derivatives and Hedging and Topic 825, Financial Instruments . Under these standards, the Company reviews available-for-sale securities for impairment whenever the fair value of the security is less than its amortized cost. If impairment exists and the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, the Company will write down the amortized cost basis to its fair value at the reporting date, recognizing the difference as a loss within other income, net in the unaudited condensed consolidated statements of operations. If the Company does not intend to sell the security nor is it more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, the Company will determine if any portion of the unrealized loss on the security is due to credit loss. If the impairment is entirely or partially due to credit loss, the Company will measure the credit loss up to the amount of the difference between fair value and amortized cost, and recognize an allowance for credit losses along with the related charge against earnings as a loss within other income, net in the unaudited condensed consolidated statements of operations. The remaining impairment amount due to all other factors is recognized in accumulated other comprehensive income (loss) in the unaudited condensed consolidated balance sheets. Subsequent changes to the Company’s estimate of credit losses will be recorded as adjustments to the allowance for credit losses and net income (loss). For the three months ended March 31, 2024, the Company determined that no impairments were required to be recognized in the unaudited condensed consolidated statements of operations. The following is a summary of cash, cash equivalents, and investments as of March 31, 2024 and December 31, 2023: Amortized Gross Gross Estimated March 31, 2024 Cash and cash equivalents $ 41,388 $ — $ — $ 41,388 Investments: U.S. treasury securities 202,619 — (863) 201,756 Total investments 202,619 — (863) 201,756 Total cash, cash equivalents, and investments $ 244,007 $ — $ (863) $ 243,144 Amortized Gross Gross Estimated December 31, 2023 Cash and cash equivalents $ 58,848 $ — $ — $ 58,848 Investments: U.S. treasury securities due in one year or less 179,843 265 (387) 179,721 Total investments 179,843 265 (387) 179,721 Total cash, cash equivalents and investments $ 238,691 $ 265 $ (387) $ 238,569 The Company considered the extent to which any unrealized losses on its marketable securities were driven by credit risk and other factors, including market risk, and if it is more-likely-than-not that the Company would have to sell the security before the recovery of the amortized cost basis. As of March 31, 2024 and December 31, 2023, the unrealized losses related to its marketable securities were due to rising market interest rates compared to when the investments were initiated. The Company does not believe the unrealized losses represent credit risk, and the Company does not intend to sell any of the securities in an unrealized loss position and it is not likely that the Company would be required to sell these securities before recovery of their amortized cost basis, which may be at maturity. Thus, no credit loss was recognized for the Company's marketable securities for the three months ended March 31, 2024 and 2023. As of March 31, 2024, the Company held $76,444 in U.S. treasury securities with maturities within one year and $125,312 in U.S. treasury securities with maturities after one year and within three years. Restricted Cash As of March 31, 2024, restricted cash totaled $185 and related to cash held as collateral for a letter of credit related to the contractual provisions for one of the Company’s office leases. The following table is a reconciliation of cash, cash equivalents, and restricted cash included in the accompanying unaudited condensed consolidated balance sheets that sum to the total cash, cash equivalents, and restricted cash included in the accompanying unaudited condensed consolidated statements of cash flows: As of March 31, 2024 2023 Cash and cash equivalents $ 41,388 $ 56,889 Restricted cash included in "other long-term assets" 185 — Cash, cash equivalents, and restricted cash $ 41,573 $ 56,889

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement The following tables summarize financial assets and liabilities measured and recorded at fair value on a recurring basis in the accompanying consolidated balance sheets as of March 31, 2024 and December 31, 2023, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: March 31, 2024 Quoted Prices in Active Markets for Identical Assets (Level 1 Inputs) Significant Other Observable Inputs (Level 2 Inputs) Significant Unobservable Inputs Total Assets: Money market funds $ 16,450 $ — $ — $ 16,450 U.S. treasury securities — 201,756 — 201,756 Commercial paper — 3,486 — 3,486 Investment loan receivable (See Note 7) — — 7,000 7,000 Total assets $ 16,450 $ 205,242 $ 7,000 $ 228,692 Liabilities: Contingent consideration $ — $ — $ 618 $ 618 Total liabilities $ — $ — $ 618 $ 618 December 31, 2023 Quoted Prices in Active Markets for Identical Assets (Level 1 Inputs) Significant Other Observable Inputs (Level 2 Inputs) Significant Unobservable Inputs Total Assets: Money market funds $ 54,269 $ — $ — $ 54,269 U.S. treasury securities — 179,721 — 179,721 Total assets $ 54,269 $ 179,721 $ — $ 233,990 Liabilities: Contingent consideration $ — $ — $ 597 $ 597 Total liabilities $ — $ — $ 597 $ 597 Cash equivalents include money market funds with original maturities of 90 days or less from the date of purchase. The fair value measurement of these assets is based on quoted market prices in active markets for identical assets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy. The Company’s investments primarily consist of U.S. treasury securities. The fair value measurement of these assets is based on significant other observable inputs and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 2 in the fair value hierarchy. As of March 31, 2024, the Company measured its investment loan receivables (see Note 7) and its contingent consideration associated with the acquisition of Datos Inc. on a recurring basis using significant unobservable inputs (Level 3). As of December 31, 2023, the Company measured its contingent consideration associated with the acquisition of Datos Inc. on a recurring basis using significant unobservable inputs (Level 3). Contingent consideration The Company records contingent consideration resulting from a business combination at its fair value on the acquisition date. The Company generally determines the fair value of the contingent consideration using the Monte Carlo simulation model. Each reporting period thereafter, these obligations are revalued and increases or decreases in their fair values are recorded as an adjustment to other income, net within the unaudited condensed consolidated statements of operations and comprehensive income (loss). Changes in the fair value of the contingent consideration can result from changes in assumed discount periods and rates, and from changes pertaining to the estimated or actual achievement of the defined milestones. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, future business and economic conditions, as well as changes in any of the assumptions described above, can materially impact the amount of contingent consideration expense the Company records in any given period. The total estimated fair value of the contingent consideration payable was $618 and $597 as of March 31, 2024 and December 31, 2023, respectively. The following table represents the key inputs used in the fair value calculations: March 31, 2024 December 31, 2023 Risk free interest rate 5.00 % 4.80 % Projected year of payment 2025 2025 Revenue volatility 10.0 % 11.0 % Discount rate 7.60 % 7.70 % Changes in the estimated fair value of the Datos contingent consideration payable will be recognized in other income, net. A rollforward of the fair value measurements of the contingent consideration liability for the three months ended March 31, 2024 is as follows: Balance as of December 31, 2023 $ 597 Change in fair value and expense recognized for service period rendered 21 Balance as of March 31, 2024 618

Other Assets	Other Assets Investment Loan Receivable In March 2024, the Company entered into a loan agreement in which it has loaned $7,000 to the borrower with a repayment date in March 2025. In addition to the loan facility, the Company entered into an option agreement with the borrower in which the Company has the right, but not the obligation, to acquire a majority of the outstanding common stock of the borrower during the period beginning July 1, 2024 and ending August 31, 2024. The Company recorded the investment loan receivable and the call option at their fair value of $7,000 on the agreement date. The carrying value of the investment loan receivable, which approximates its fair value, is recorded in prepaid expenses and other current assets in the unaudited condensed consolidated balance sheet as of March 31, 2024. With respect to its investment loan receivable, the Company held a variable interest in the borrower, which is a variable interest entity. After evaluation of the relationship between the Company and this variable interest entity, the Company determined not to consolidate this variable interest entity’s results of operations for the three months ended March 31, 2024. Significant judgments included the determination that the Company was not the primary beneficiary of the variable interest entity given the Company’s variable interests did not constitute a controlling financial interest. The Company elected to account for this investment by utilizing the fair value option. The Company records investment loan receivables at their fair value on the agreement date. Each reporting period thereafter, these receivables are revalued and increases or decreases in their fair values are recorded as an adjustment to other income, net within the unaudited condensed consolidated statements of operations and comprehensive income (loss). The Company generally determines the fair value using the discounted cash flow method. The significant assumptions used to estimate the fair value include the interest rate, risk-free rate, expected repayment date, equity value, equity volatility, expected timing of exercise, and the credit spread assumption specific to the investment loan. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	Net Income (Loss) Per Share For the three months ended March 31, 2024, diluted net income per share was calculated by dividing net income attributable to Semrush Holdings, Inc. by the weighted-average number of shares of common stock outstanding during the period, including the dilutive impact of stock options and shares of common stock issuable upon the vesting of Restricted Stock Units (“RSUs”). For the three months ended March 31, 2023, the net loss attributable to common stockholders is divided by the weighted-average number of shares of common stock outstanding during the period to calculate both basic and diluted earnings per share. The dilutive effect of common stock equivalents has been excluded from the calculation of diluted net loss per share for these periods as its effect would have been anti-dilutive due to the net losses incurred for the periods. The following table presents a reconciliation of weighted-average shares outstanding used in the calculation of basic and diluted net income (loss) per share: Three Months Ended March 31, 2024 2023 Weighted-average shares outstanding: Weighted-average number of shares of common stock used in computing net income (loss) per share attributable to common stockholders—basic 144,565,578 141,650,459 Dilutive effect of share equivalents resulting from stock options 2,193,289 — Dilutive effect of share equivalents resulting from restricted stock units 938,634 — Weighted-average number of shares of common stock used in computing net income (loss) per share attributable to common stockholders—diluted 147,697,501 141,650,459 The following potentially dilutive common stock equivalents, including stock options and restricted stock units, have been excluded from the calculation of diluted weighted-average shares outstanding for the three months ended March 31, 2024 and 2023 because to do so would have been anti-dilutive for the periods presented: Three Months Ended March 31, 2024 2023 Stock options outstanding 3,515,132 7,502,992 Unvested RSUs 539,969 1,770,736 Unvested Performance stock units (“PSUs”) 319,976 — 4,375,077 9,273,728 For the three months ended March 31, 2024 and 2023, 1,198,606 and 1,328,021 shares of Class A common stock potentially issuable under PSU awards were excluded from the table above, respectively. The performance-based conditions had not been met and were deemed improbable of achievement as of the reporting period end date.

Acquisitions, Intangible Assets, and Goodwill	Acquisitions, Intangible Assets, and Goodwill Acquisitions Datos On December 1, 2023, the Company completed a stock purchase agreement to acquire approximately 60% of the voting equity interests in Datos Inc. (“Datos”). The Company has accounted for this transaction as a business combination under the acquisition method. The primary purpose of this business combination is to acquire Datos’ valuable clickstream data software. The Company performed acquisition accounting as of December 1, 2023. The acquisition date fair value of the consideration transferred consisted of the following: Acquisition Date Consideration transferred Fair Value Fair value of the January 2021 and February 2022 Convertible Notes $ 7,530 Cash paid at close 4,255 Other consideration 2,070 Total purchase consideration $ 13,855 The Company determined that the fair value of the assets acquired and liabilities assumed was $19,021, including the fair value of the noncontrolling interest in Datos of $5,166. The fair value of the noncontrolling interest is inclusive of the fair value of the acquired call option, which gives the Company the right, but not the obligation, to purchase the remaining shares in Datos during the period beginning January 1, 2026 and ending on January 1, 2027 (the “Call Option”). The Company estimated the fair value of the noncontrolling interest, inclusive of the Call Option, using an option pricing method (a special case of the income approach), considering the initial transaction price and based on Level 3 significant unobservable inputs such as the total equity value of Datos, forecasted revenues, volatility, and risk-adjusted discount rates. Other consideration includes the deferred purchase payments, the contingent payment, and additional consideration due to the seller. A payment of $501 was made during March 2024 related to other consideration. The remaining fair value of other consideration has been recorded to other current liabilities in the unaudited condensed consolidated balance sheet as of March 31, 2024. The table below summarizes the Company’s preliminary purchase price allocation.

As of December 1, 2023, the results of Datos’ operations are included within the Company’s consolidated financial statements. This business combination did not have a material impact on the Company’s consolidated financial statements. Therefore, actual results of operations subsequent to the acquisition date and pro forma results of operations have not been presented. Traffic Think Tank On February 23, 2023, the Company completed a purchase agreement with Rank, LLC (“Traffic Think Tank”), acquiring certain intangible assets of Traffic Think Tank for total cash consideration of $1,800, of which $360 will be paid in 12 months (the “12-month holdback amount”) and $360 will be paid in 18 months (the “18-month holdback amount”). The remaining consideration was paid upon closing. The 12-month holdback amount and 18-month holdback amount are recorded in other current liabilities in the unaudited condensed consolidated balance sheet as of March 31, 2024. The primary purpose of the acquisition was to acquire valuable brand and content related to Traffic Think Tank’s SEO community and courses.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is subject to income taxes in U.S. federal, state, and foreign jurisdictions. For the three months ended March 31, 2024 and 2023, the Company recorded provisions for income taxes of $3,104 and $797, respectively. The Company’s effective tax rate for the three months ended March 31, 2024 differs from the U.S. statutory rate due primarily to the impact of earnings in foreign jurisdictions and the impact of the requirement to capitalize and amortize certain research and development costs which results in a current U.S. tax provision but no deferred tax benefit as a result of the valuation allowance maintained against our net deferred tax assets. The Company’s income tax expense for the three months ended March 31, 2023 primarily relates to income earned in certain foreign jurisdictions. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. These differences are measured using the enacted statutory tax rates that are expected to be in effect for the years in which differences are expected to reverse. On a periodic basis, the Company reassesses any valuation allowances it maintains on its deferred tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. The Company maintains a valuation allowance on its net deferred tax assets.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company recorded stock-based compensation expense of $5,115 and $2,796 during the three months ended March 31, 2024 and 2023, respectively. The following table shows stock-based compensation expense by where the stock-based compensation expense is recorded in the Company’s unaudited condensed consolidated statement of operations: Three Months Ended 2024 2023 Cost of revenue $ 39 $ 17 Sales and marketing 770 528 Research and development 636 343 General and administrative 3,670 1,908 Total stock-based compensation $ 5,115 $ 2,796 As of March 31, 2024, there was $15,790 of unrecognized compensation cost related to unvested common stock option arrangements, which is expected to be recognized over a weighted-average period of 2.66 years. As of March 31, 2024, there was $33,975 of unrecognized compensation cost related to unvested restricted stock unit awards, which is expected to be recognized over a weighted-average period of 2.76 years. As of March 31, 2024, there was $11,463 of unrecognized compensation cost related to unvested performance stock unit awards, which is expected to be recognized over a weighted-average period of 2.92 years. The fair value of each option award was estimated on the date of grant using the Black-Scholes option-pricing model. As there was no public market for its common stock prior to March 25, 2021, which was the first day of trading, and as the trading history of the Company’s common stock is limited, the Company determined the expected volatility for options granted based on an analysis of reported data for a peer group of companies that issued options with substantially similar terms. The expected volatility of options granted has been determined using an average of the historical volatility measures of this peer group of companies. The expected life of options granted to employees was calculated using the simplified method, which represents the average of the contractual term of the option and the weighted-average vesting period of the option. The Company uses the simplified method because it does not have sufficient historical option exercise data to provide a reasonable basis upon which to estimate expected term. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of the share option. The Company has not paid, nor anticipates paying, cash dividends on its ordinary shares; therefore, the expected dividend yield is assumed to be zero. The weighted-average assumptions utilized to determine the fair value of options granted to employees are presented in the following table: Three Months Ended March 31, 2024 2023 Expected volatility 61.8 % 63.6 % Weighted-average risk-free interest rate 4.28 % 4.22 % Expected dividend yield — — Expected life – in years 6 6 A summary of the Company’s option activity as of March 31, 2024, and changes during the three months then ended are as follows: Number of Options Weighted-Average Exercise Price (per share) Weighted-Average Remaining Contractual Term (in years) Outstanding at January 1, 2024 7,175,494 $ 7.02 7.78 Granted 15,888 12.62 Exercised (469,879) 1.80 Forfeited (265,242) 8.47 Outstanding at March 31, 2024 6,456,261 7.36 7.60 Options exercisable at March 31, 2024 3,183,237 4.60 6.41 The weighted-average grant-date fair value of options granted during the three months ended March 31, 2024 was $7.71 per share. The weighted-average grant-date fair value of options granted during the three months ended March 31, 2023 was $4.93 per share. No tax benefits were realized from options during the three months ended March 31, 2024 and 2023, respectively. The aggregate intrinsic value of options outstanding as of March 31, 2024 and December 31, 2023 was $39,769 and $49,221, respectively. The aggregate intrinsic value for options exercised during the three months ended March 31, 2024 was $5,035. The aggregate intrinsic value for options exercised during the three months ended March 31, 2023 was $708. The aggregate intrinsic value for options exercisable as of March 31, 2024 and December 31, 2023 was $28,574 and $34,471, respectively. The aggregate intrinsic value was calculated based on the positive difference, if any, between the estimated fair value of the Company’s common stock on March 31, 2024 and December 31, 2023, respectively, or the date of exercise, as appropriate, and the exercise price of the underlying options. During the three months ended March 31, 2024 and 2023, the Company granted to employees RSUs for 1,439,963 and 523,294 shares of Class A common stock, respectively. During the three months ended March 31, 2024 and 2023, the Company recorded stock-based compensation expense related to the RSUs of $3,007 and $1,191, respectively.

Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses suffered or incurred as a result of claims of intellectual property infringement. These indemnification agreements are provisions of the applicable customer agreement. Based on when clients first sign an agreement for the Company’s service, the maximum potential amount of future payments the Company could be required to make under certain of these indemnification agreements is unlimited. Based on historical experience and information known as of March 31, 2024, the Company has not incurred any costs for the above guarantees and indemnities. In certain circumstances, the Company warrants that its services will perform in all material respects in accordance with its standard published specification documentation in effect at the time of delivery of the services to the customer for the term of the agreement. To date, the Company has not incurred significant expense under its warranties and, as a result, the Company believes the estimated fair value of these agreements is immaterial.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The unaudited condensed consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements as of and for the year ended December 31, 2023, and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of March 31, 2024, and for the three months ended March 31, 2024 and 2023. The consolidated balance sheet as of December 31, 2023 included herein was derived from the audited consolidated financial statements as of that date. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, any other interim periods, or any future year or period. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 7, 2024. The accompanying unaudited condensed consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the unaudited condensed consolidated financial statements. As of March 31, 2024, there have been no material changes in the Company's significant accounting policies from those that were disclosed in the Annual Report on Form 10-K, except as discussed below.
Principles of Consolidation	Principles of Consolidation
Use of Estimates	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, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these unaudited condensed consolidated financial statements include, but are not limited to, revenue recognition, expected future cash flows used to evaluate the recoverability of long-lived assets, contingent liabilities, expensing and capitalization of research and development costs for internal-use software, the average period of benefit associated with costs capitalized to obtain revenue contracts, the determination of the fair value of stock-based awards issued, stock-based compensation expense, the determination of the estimated fair value of loan receivables and convertible notes held by the Company, the valuations of the intangible assets acquired through acquisitions, the estimation of the Company’s incremental borrowing rate, and the recoverability of the Company’s net deferred tax assets and related valuation allowance. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made.
Subsequent Events Considerations	Subsequent Events Considerations The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the unaudited condensed consolidated financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. See Note 19 for additional information regarding the Company’s subsequent events.
Revenue Recognition	Revenue Recognition The Company primarily derives revenue from subscriptions to the Company’s SaaS services and related customer support. For the three months ended March 31, 2024 and 2023, subscription revenue accounted for nearly all of the Company’s revenue. Revenue related to other revenue was not material for the three months ended March 31, 2024 and 2023. The Company offers subscriptions to its platform primarily on a monthly or annual basis. The Company sells its products and services primarily through a self-service model and also directly through its sales force. The Company’s subscription arrangements provide customers the right to access the Company’s hosted software applications. Customers do not have the right to take possession of the Company’s software during the hosting arrangement. Subscriptions are generally non-cancellable during the contractual subscription term; however, subscription contracts contain a right to a refund if requested within seven days of purchase. The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration it expects to receive in exchange for those products or services. There were no changes to the Company’s revenue recognition policies since the filing of its Annual Report on Form 10-K with the SEC on March 7, 2024. Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. The Company primarily invoices and collects payments from customers for its services in advance on a monthly or annual basis. Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as deferred revenue, and the remaining portion is recorded as deferred revenue, net of current portion. Deferred revenue increased by $5,650 as of March 31, 2024 compared to December 31, 2023. During the three months ended March 31, 2024 and 2023, $30,351 and $25,513 of revenue was recognized that was included in deferred revenue as of December 31, 2023 and 2022, respectively. The Company has elected to exclude amounts charged to customers for sales tax from the transaction price. Accordingly, revenue is presented net of any sales tax collected from customers. Transaction Price Allocated to Future Performance Obligations ASC 606 requires that the Company disclose the aggregate amount of the transaction price that is allocated to performance obligations that have not yet been satisfied as of the balance sheet dates reported. For contracts with an original expected duration greater than one year, the aggregate amount of the transaction price allocated to the performance obligations that were unsatisfied as of March 31, 2024 was $1,386, of which the Company expects to recognize $1,080 over the next 12 months. For contracts with an original expected duration of one year or less, the Company has applied the practical expedient available under ASC 606 to not disclose the amount of transaction price allocated to unsatisfied performance obligations as of March 31, 2024. For performance obligations not satisfied as of March 31, 2024, and to which this expedient applies, the nature of the performance obligations is consistent with performance obligations satisfied as of December 31, 2023. Costs to Obtain a Contract The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and recorded as deferred contract costs in the unaudited condensed consolidated balance sheets and are amortized over a period of approximately 24 months on a systematic basis, consistent with the pattern of transfer of the goods or services to which the asset relates. The 24-month period represents the estimated benefit period of the customer relationship and has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period based on historical experience and future expectations. Deferred contract costs that will be recorded as expense during the succeeding 12-month period are recorded as deferred contract costs, current portion, and the remaining portion is recorded as deferred contract costs, net of current portion. Amortization of deferred contract costs is included in sales and marketing expense in the accompanying unaudited condensed consolidated statements of operations and comprehensive income (loss).
Concentrations of Credit Risk and Significant Customers	Concentrations of Credit Risk and Significant Customers The Company has no off-balance sheet risk, such as foreign exchange contracts, option contracts, or other hedging arrangements. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company's accounts receivable. Credit risk with respect to accounts receivable is dispersed due to the large number of customers of the Company. The Company routinely assesses the creditworthiness of its customers and generally does not require its customers to provide collateral or other security to support accounts receivable. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company's accounts receivable.
Disclosure of Fair Value of Financial Instruments	Disclosure of Fair Value of Financial Instruments The Company’s financial instruments include cash, cash equivalents, investments, accounts receivable, loan receivables, accounts payable, and accrued expenses. The Company’s investments are classified as available-for-sale and reported at fair value in accordance with the market approach utilizing quoted prices that were directly or indirectly observable. The Company has elected the fair value option in respect to the accounting for its loan receivable investment, resulting in increases and decreases in the fair value of such investments being recorded to other income, net for each reporting period. The carrying amount of the remainder of the Company’s financial instruments approximated their fair values as of March 31, 2024 and December 31, 2023, due to the short-term nature of these instruments. Cash equivalents include money market funds with original maturities of 90 days or less from the date of purchase. The fair value measurement of these assets is based on quoted market prices in active markets for identical assets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy. The Company’s investments primarily consist of U.S. treasury securities. The fair value measurement of these assets is based on significant other observable inputs and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 2 in the fair value hierarchy.
Foreign Currency Translation	Foreign Currency Translation
Comprehensive Income (Loss)	Comprehensive income (loss) Comprehensive income (loss) is comprised of two components: net income (loss) and other comprehensive income (loss), which includes other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. For the three months ended March 31, 2024 and 2023 , comprehensive income (loss) consists of net income (loss), the change in the cumulative foreign currency translation adjustment, and unrealized loss on investments. The tax effect of the cumulative foreign currency translation adjustment and unrealized loss on investments was not significant for the three months ended March 31, 2024 and 2023
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”) . ASU 2023-07 expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of adopting ASU 2023-07 on its consolidated financial statements and 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 requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, ASU 2023-09 requires certain disclosures of state versus federal income tax expense and taxes paid. The amendments in ASU 2023-09 are required to be adopted for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied on a prospective basis although retrospective application is permitted. The Company is evaluating the impact of adopting ASU 2023-09 on its consolidated financial statements and disclosures.
