Accounting Policies [Abstract] | |
Summary of Business and Significant Accounting Policies | (1) Summary of Business and Significant Accounting Policies Description of Business Amplitude, Inc. (the “Company”) was incorporated in the state of Delaware in 2011 and is headquartered in San Francisco, California. The Company provides a Digital Analytics Platform that helps businesses understand how people are using their digital products so they can improve the digital experience provided by those digital products. The Company delivers its application over the Internet as a subscription service using a software-as-a-service (“SaaS”) model. The Company’s arrangements with customers do not provide the customer with the right to take possession of the software supporting the cloud-based application service at any time. The Company also offers customer support related to initial implementation setup, ongoing support services, and application training. Segment Information The Company has a single operating and reportable segment. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, and allocating resources. Long-lived assets outside of the United States are immaterial. For information regarding the Company’s revenue by geographic area, see the Disaggregation of Revenue section below. Basis of Presentation and Principles of Consolidation The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP” or “GAAP”) and include the accounts of Amplitude, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Foreign Currency The reporting currency of the Company is the United States dollar. The functional currency of the Company’s foreign subsidiaries is also the United States dollar. Foreign currency transaction gains and losses are recognized in “Other income (expense), net” in the consolidated statements of operations and comprehensive loss, and have not been material for any of the periods presented. Direct Listing On September 21, 2021, the Company’s registration statement (the “Registration Statement”) related to the direct listing of the Company's Class A common stock on the Nasdaq Capital Market (the “Direct Listing”) was declared effective by the SEC, and on September 28, 2021, the Company’s Class A common stock commenced trading. The Company incurred fees related to financial advisory service, audit, and legal expenses in connection with the Direct Listing and recorded general and administrative expenses of $ 18.2 million for the year ended December 31, 2021. Prior to the Direct Listing, on August 30, 2021, an amended and restated certificate of incorporation of the Company was filed with the Secretary of State of the State of Delaware, which resulted in the creation of Class A common stock and Class B common stock. All existing shares of common stock issued and outstanding were reclassified into shares of Class B common stock. Upon the effectiveness of the Registration Statement, all 68.0 million outstanding shares of redeemable convertible preferred stock were converted into an equivalent number of shares of Class B common stock. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates are based on information available as of the date of the financial statements and may involve subjective or significant judgment by the Company; therefore, actual results could differ from the Company’s estimates. Items subject to such estimates and assumptions include, but are not limited to the: • expected period of benefit for deferred commissions; • useful lives of long-lived assets; • valuation of goodwill and intangible assets; • recognition, measurement, and valuation of deferred tax assets and income tax uncertainties; and • incremental borrowing rates used for operating leases. Revenue Recognition The Company derives revenue primarily from sales of subscription services. Revenue is recognized when, or as, the related performance obligation is satisfied by transferring the control of the promised service to a customer. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these services. To achieve the core principle of the revenue standard, the Company applies the following steps: (i) Identification of the contract, or contracts, with the customer The Company considers the terms and conditions of the contract in identifying the contracts. The Company determines a contract with a customer to exist when the contract is approved, each party’s rights regarding the services to be transferred can be identified, the payment terms for the services can be identified, it has been determined the customer has the ability and intent to pay, and the contract has commercial substance. At contract inception, the Company will evaluate whether two or more contracts should be combined and accounted for as a single contract and whether the combined or single contract includes more than one performance obligation. The Company applies judgment in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit, and financial information pertaining to the customer. (ii) Identification of the performance obligations in the contract Performance obligations promised in a contract are identified based on the services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the service either on its own or together with other resources that are readily available from third parties or from the Company and are distinct in the context of the contract, whereby the transfer of the services and the products is separately identifiable from other promises in the contract. The Company’s performance obligations consist of (1) core subscription services and (2) professional and other services. (iii) Determination of the transaction price The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring services to the customer. The transaction price includes SaaS subscription fees based on the contracted usage as well as variable consideration associated with overage fees on exceeded volume limits. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of the Company’s contracts contain a significant financing component. (iv) Allocation of the transaction price to the performance obligations in the contract Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on each performance obligation’s relative standalone selling price. Contracts typically have one performance obligation of providing access to the core subscription service. On occasion, contracts include professional services to customers, which are separate performance obligations. Professional services revenue has historically not been significant. (v) Recognition of the revenue when, or as, a performance obligation is satisfied Revenue is recognized at the time the related performance obligation is satisfied by transferring the control of the promised service to a customer. For subscription services, revenue is recognized as the customer is given access to the core subscription service, in an amount that reflects the consideration that the Company expects to receive in exchange for access to the services. With respect to professional services, the Company recognizes revenue as services are delivered. The Company generates all its revenue from contracts with customers. Subscription revenue The Company generates revenue from subscription services including SaaS subscriptions and customer support services subject to contractual subscription terms. SaaS subscriptions enable customers to access and send event volume data to the Company’s cloud-based platform. Subscription arrangements with customers do not provide the customer with the right to take possession of the Company’s software at any time. Instead, customers are granted continuous access to the platform over the contractual period. A time-elapsed method is used to measure progress because the Company’s obligation is to provide continuous service over the contractual period and control is transferred evenly over the contractual period. Accordingly, the fixed consideration related to subscription revenue is recognized ratably over the contract term beginning on the date access to the subscription product is provisioned. The typical subscription term is 12 months with various payment terms ranging from monthly to annual up-front payments. Most contracts are non-cancellable over the contractual term and are subject to standard terms and conditions; however, certain contracts contain nonstandard terms that may impact the timing of revenue recognition. Some customers have the option to purchase additional subscription services at a stated price. These options are evaluated on a case-by-case basis but generally do not provide a material right as they do not provide a discount to the customer that is incremental to the range of discounts typically given for the same services that are sold to a similar class of customers, even when the stand-alone selling price of the services subject to the option is highly variable. Remaining performance obligations The Company’s contracts with customers generally include one combined performance obligation, its core subscription offering, which is a series of distinct services transferred to the customer ratably over the respective obligation’s term. Other performance obligations that may be identified in contracts include professional services. As of December 31, 2023, the unrecognized transaction price related to remaining performance obligations was $ 239.4 million . The Company’s remaining performance obligations as of December 31, 2023 are expected to be recognized as follows (in thousands): As of December 31, 2023 2022 Less than or equal to 12 months $ 188,456 $ 190,595 Greater than 12 months 50,962 57,581 Total remaining performance obligations $ 239,418 $ 248,176 Disaggregation of Revenue The following table shows the Company’s disaggregation of revenue by geographic areas, as determined based on the address of the Company's customers (in thousands): Year Ended 2023 2022 2021 United States $ 167,919 $ 146,415 $ 107,244 International 108,365 91,652 60,017 Total revenue $ 276,284 $ 238,067 $ 167,261 Accounts Receivable, Net Accounts receivable are primarily comprised of cash due from customers and are recorded at the invoiced amount, net of an allowance for doubtful accounts.

In determining the necessary allowance for doubtful accounts, the Company estimates the lifetime expected credit losses against the existing accounts receivable balance. The Company's estimate is based on certain factors including historical loss rates, current economic conditions, reasonable and supportable forecasts, and customer-specific circumstances. The Company maintained an allowance of $ 1.1 million and $ 0.7 million for doubtful accounts as of December 31, 2023 and 2022 , respectively. The movements in the allowance for doubtful accounts were not material for any of the periods presented. The Company does not have any off-balance-sheet credit exposure related to its customers. Concentration of Risk and Significant Customers Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, marketable securities, and accounts receivable. Although the Company deposits its cash with high-quality, credit-rated financial institutions, the deposits, at times, may exceed federally insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. No customer accounted for 10 % or more of total revenue for the years ended December 31, 2023, 2022, and 2021. As of the year ended December 31, 2023, o ne customer represented 10 % of accounts receivable. As of the year end December 31, 2022 no customers represented 10 % or more of accounts receivable. Deferred Revenue Deferred revenue consists of billings of payments received in advance of revenue recognition and is recognized when, or as, performance obligations are satisfied. The Company generally invoices its customers annually or in semi-annual, quarterly, or monthly installments. Accordingly, the deferred revenue balance does not represent the total contract value of annual non-cancellable subscription agreements. The amount of revenue recognized in the years ended December 31, 2023 and 2022 that was included in deferred revenue at the beginning of the period was $ 89.6 million and $ 68.8 million, respectively. Deferred Commissions The Company capitalizes sales commissions that are recoverable and incremental due to the acquisition of customer contracts. The Company determines whether costs should be deferred based on its sales compensation plans, if the commissions are in fact incremental and would not have occurred absent the customer contract. Commissions paid upon the initial acquisition of a contract are deferred and then amortized on a straight-line basis over a period of benefit, determined to be five years. The period of benefit is estimated by considering factors such as the expected life of our subscription contracts, historical customer attrition rates, technological life of our platform, as well as other factors. Sales commissions for renewal of a subscription contract are not considered commensurate with the commissions paid for the acquisition of the initial subscription contract given the substantive difference in commission rates between new and renewal contracts. The Company determines the period of benefit for renewal subscription contracts by considering the contractual term for renewal contracts. Amounts anticipated to be recognized within 12 months of the balance sheet date are recorded as deferred commissions, current, with the remaining portion recorded as deferred commissions, noncurrent, in the consolidated balance sheets. Amortization of deferred commissions is included in sales and marketing expense in the consolidated statement of operations and comprehensive loss. The Company periodically reviews these deferred commissions to determine whether events or changes in circumstances have occurred that could impact recoverability or the period of benefit. There were no impairment losses recorded during the periods presented. The following table represents a roll-forward of the Company’s deferred commissions as of December 31, 2023 and 2022 (in thousands): Year Ended 2023 2022 Beginning balance $ 36,717 $ 28,685 Additions to deferred commissions 13,656 17,740 Amortization of deferred commissions ( 11,987 ) ( 9,708 ) Ending balance 38,386 36,717 Deferred commissions, current portion 11,444 10,918 Deferred commissions, net of current portion 26,942 25,799 Total deferred commissions $ 38,386 $ 36,717 Cost of Revenue Cost of revenue primarily consists of costs related to third-party hosting costs; employee-related expenses, including salaries, stock-based compensation and benefits for operations and support personnel; software license fees; certain developed technology and acquired developed software amortization; and allocated overhead. Research and Development Expense The Company’s costs related to research, design, maintenance, and minor enhancements of the Company’s platform are expensed as incurred. These costs consist primarily of personnel-related expenses, including stock-based compensation and allocated overhead costs, contractor and consulting fees related to the design, development, testing, and enhancements of the Company’s platform, and software, hardware, and cloud infrastructure fees for staging and development related to research and development activities necessary to support growth in the Company’s employee base and in the adoption of its platform. Advertising Costs The Company expenses all advertising costs as incurred as a component of sales and marketing expenses. Advertising expenses of $ 5.5 million , $ 5.8 million , and $ 4.5 million were incurred during the years ended December 31, 2023, 2022 , and 2021, respectively. Stock-Based Compensation The Company records stock-based compensation expense for all stock-based awards, including stock options, restricted stock units (“RSUs”) and purchase rights issued under the 2021 Employee Stock Purchase Plan (“ESPP”), made to employees, non-employees, and directors based on estimated fair values recognized over the requisite service period. The Company measures and recognizes compensation expense for all stock-based payment awards granted to employees, directors, and non-employees based on the estimated fair values on the date of the grant and vesting criteria. For options, vesting is typically over a four-year period and is contingent upon continued employment on each vesting date. In general, options granted to newly hired employees vest ratably each month over a 36-month period to 48-month period. RSUs typically vest ratably each quarter over a three-year period and is contingent upon continued employment on each vesting date. The Company recognizes compensation expense for service-based stock-based awards as an expense over the employee’s or director’s requisite service period on a straight-line basis. The Company also has certain options and awards that have performance-based vesting conditions upon certain liquidity events. As a result of the Direct Listing, the liquidity event was met for all outstanding awards with a performance condition and therefore the related expense was recognized using the accelerated attribution method. Forfeitures are accounted for as they occur. Stock-based compensation expense is allocated to cost of revenue and operating expenses on the consolidated statements of operations and comprehensive loss based on where the associated employee’s functional department is located. The fair value of stock options granted under the 2021 Plan and purchase rights issued under the ESPP for purposes of calculating stock-based compensation expense is estimated on the grant date using the Black-Scholes pricing model. The Black-Scholes pricing model requires the Company to make assumptions and judgments about the inputs used in the calculation, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the volatility of the Company’s common stock, risk-free interest rate, and expected dividend yield. The expected term represents the period that the Company’s stock-based awards are expected to be outstanding. For stock options considered to be “plain vanilla” options, the Company estimates the expected term based on the simplified method, which is essentially the weighted average of the vesting period and contractual term, as the Company's historical option exercise experience does not provide a reasonable basis upon which to estimate the expected term. The volatility is based on an average of the historical volatilities of the common stock of comparable public companies with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option or purchase right. The Company’s expected dividend yield input is zero as it has not historically paid, nor does it expect in the future to pay, cash dividends on its common stock. Stock-based compensation expense for RSUs granted under the 2021 Plan is measured based on the fair value of the underlying shares on the date of grant. Taxes Income taxes are accounted for under the asset-and-liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income or loss in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established for deferred tax assets to the extent it is more likely than not that the deferred tax assets may not be realized. The Company evaluates uncertain tax positions taken or expected to be taken in the course of preparing its tax return to determine whether the tax positions are more likely than not of being sustained upon challenge by the applicable tax authority. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Cash, Cash Equivalents, and Restricted Cash The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents are stated at fair value. Restricted cash represents cash held to collateralize lease obligations related to the Company's property leases. As of December 31, 2023 and 2022, $ 0.9 million of restricted cash is recorded as noncurrent assets. T he following table represents the Company's cash, cash equivalents, and restricted cash at each period end (in thousands): As of December 31, 2023 2022 Cash and cash equivalents $ 248,491 $ 218,494 Restricted cash, noncurrent 869 855 Total cash, cash equivalents, and restricted cash $ 249,360 $ 219,349 Investments in Marketable Securities Investments in marketable securities consist of commercial paper, corporate notes, and bonds, as well as U.S. Treasury and government agency securities. Management determines the appropriate classification of investments at the time of purchase and reevaluates such determination at each balance sheet date. Marketable securities are classified as available-for-sale and are carried at fair value in the consolidated balance sheets and are classified as short-term or long-term based on their remaining contractual maturities. The Company evaluates its investments with unrealized loss positions at the individual security level to determine whether the unrealized loss was related to credit or noncredit factors. The Company considers whether a credit loss exists based on the extent of the unrealized loss position, any adverse conditions specifically related to the security or the issuer's operating environment, pay structure of the security, the issuer's payment history and any changes in the issuer's credit rating. Estimated credit losses are determined using a discounted cash flow model and recorded as an allowance, with changes in expected credit losses on the Company's investments recorded in “Other income (expense), net” in the consolidated statements of operations and comprehensive loss. Unrealized gains and losses related to noncredit factors are reflected in “Accumulated other comprehensive loss” on the consolidated balance sheets. Fair Value Measurements The Company determines fair value based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. These levels are: Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date for assets or liabilities; the fair value hierarchy gives the highest priority to Level 1 inputs. Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date; the fair value hierarchy gives the lowest priority to Level 3 inputs. Observable inputs are based on market data obtained from independent sources. The fair value of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued liabilities approximated their carrying values as of December 31, 2023 and 2022 due to their short-term nature. The fair values of all of these instruments are categorized as Level 1 in the fair value hierarchy. The fair value of the Company's marketable securities as categorized by the fair value level hierarchy is detailed in Note 3. Business Combinations The Company applies a screen test to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets to determine whether a transaction is accounted for as an asset acquisition or business combination. When the Company acquires a business, the purchase consideration is allocated to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated respective fair value based on the acquisition method of accounting. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, particularly to acquired intangible assets. These assumptions include, but are not limited to, reproduction costs and appropriate discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Acquisition costs, such as legal and consulting fees, are expensed as incurred. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the consolidated statement of operations and comprehensive loss. Goodwill and Other Acquired Intangible Assets Goodwill represents the excess of the purchase price over the fair value of net assets acquired in connection with business combinations accounted for using the acquisition method of accounting. The Company has one reporting unit and performs testing of goodwill in the fourth quarter of each year, or as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. These triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows. The Company’s test for goodwill impairment starts with a qualitative assessment to determine whether it is necessary to perform the quantitative goodwill impairment test. If the Company determines, based on the qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, then a quantitative goodwill impairment test is required. There were no impairments of goodwill recorded for the years ended December 31, 2023, 2022, and 2021. Intangible assets mainly consist of developed technology resulting from the Company’s acquisitions. Acquired intangible assets are recorded at cost, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives, which was determined to be three years for all acquired intangibles. For developed technology, amortization costs were included within cost of revenue in the consolidated statements of operations upon the related product release date. Long-lived assets, including intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. There was no impairment of intangible assets recorded for the years ended December 31, 2023, 2022 , and 2021. Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated on a straight-line basis over the estimated useful lives of those assets, as follows: Property Useful Life Office equipment 3 years Furniture and fixtures 3 years Leasehold improvements Shorter of remaining lease term or 5 years Software including internal-use software 3 years Maintenance and repairs are charged to expense as incurred and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation is removed from the accounts and any resulting gain or loss is reflected in the statements of operations and comprehensive loss for the period realized. Operating Leases The Company determines if an arrangement is, or contains, a lease at inception. Leases arise from contractual obligations that convey the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company determines whether an arrangement is or contains a lease at inception, based on whether there is an identified asset and whether the Company controls the use of the identified asset throughout the period of use. At lease commencement date, the Company determines lease classification between finance and operating, allocates the consideration to the lease and non-lease components and recognizes a right-of-use (“ROU”) asset and corresponding lease liability for each lease component. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments based on the lease contracts. Operating lease ROU assets and liabilities were recognized at adoption date or lease commencement date, based on the present value of lease payments over the remaining lease term. The Company’s lease contracts do not provide an implicit rate, as such the Company used its incremental borrowing rate based on the information available at adoption date or lease commencement date, if the commencement date was after January 1, 2022, in determining the present value of lease payments. The operating lease ROU assets also include any lease payments made to the lessors at or before the lease commencement date, and excludes lease incentives. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The lease liability is initially measured as the present value of the remaining lease payments over the lease term. The discount rate used to determine the present value is the Company's incremental borrowing rate unless the interest rate implicit in the lease is readily determinable. The Company estimates the incremental borrowing rate based on the information available at lease commencement date for borrowings with a similar term. The ROU asset is initially measured as the present value of the lease payments, adjusted for initial direct costs, prepaid lease payments to lessors and lease incentive |

The Company uses quoted prices in active markets for identical assets to determine the fair value of the Company's Level 1 investments. The fair value of the Company's Level 2 investments is determined using pricing based on quoted market prices or alternative market observable inputs. The fair value of the Company's available-for-sale securities as of December 31, 2023, by remaining contractual maturities, was as follows (in thousands): As of December 31, 2023 Due in one year or less $ 73,909 Due in greater than one year — Total $ 73,909 The Company periodically evaluates its investments for expected credit losses. The unrealized losses on the available-for-sale securities were primarily due to unfavorable changes in interest rates subsequent to the initial purchase of these securities. None of the Company's available-for-sale securities have been in a continuous unrealized loss position for twelve months or longer as of December 31, 2023. The Company expects to recover the full carrying value of its available-for-sale securities in an unrealized loss position as it does not intend or anticipate a need to sell these securities prior to recovering the associated unrealized losses. The Company also expects any credit losses would be immaterial based on the high-grade credit rating for each of such available-for-sale securities. As a result, the Company does not consider any portion of the unrealized losses as of December 31, 2023 and 2022 to represent a credit loss. |

Stockholders' Equity (Deficit) and Equity Incentive Plans | (5) Stockholders’ Equity and Equity Incentive Plans Preferred stock In connection with the Direct Listing on September 21, 2021, an amended and restated certificate of incorporation of the Company was filed with the Secretary of State of the State of Delaware, which authorized the issuance of 20 million shares of undesignated preferred stock with a par value of $ 0.00001 per share and rights and preferences, including voting rights, designated from time to time by the Company's board of directors. Common Stock The Company has two classes of common stock: Class A common stock and Class B common stock. The Company's amended and restated certificate of incorporation authorizes the issuance of 600 million shares of Class A common stock and 600 million shares of Class B common stock. The shares of Class A common stock and Class B common stock are identical, except with respect to voting, conversion, and transfer rights. Each share of Class A common stock is entitled to one vote . Each share of Class B common stock is entitled to five votes . Class A and Class B common stock each have a par value of $ 0.00001 per share and are referred to as common stock throughout the notes to the consolidated financial statements, unless otherwise noted. Holders of common stock are entitled to receive any dividends whenever funds are legally available and if declared by the Company's board of directors. Shares of Class B common stock may be converted to Class A common stock at any time at the option of the stockholder. Shares of Class B common stock will also automatically convert into one share of Class A common stock upon any transfer, except for certain permitted transfers described in the Company's amended and restated certificate of incorporation. In addition, each share of Class B common stock held by the Company's three cofounders (or any of such founder’s affiliates) will convert automatically into one share of Class A common stock on the earlier of: (i) the death or incapacity of such founder or (ii) the date that is six months following the date on which such founder is no longer an employee or director of the Company (unless such founder has rejoined the Company during such six-month period). Each outstanding share of the Company's Class B common stock will also convert automatically into one share of Class A common stock on the date that is six months following the date on which no founder is an employee or director of the Company (unless a founder has rejoined the Company during such six-month period). In addition, any transfer by a founder (or such founder’s affiliates) to one or more of the other founders (or such founders’ affiliates) will not result in the automatic conversion of such shares of Class B common stock to Class A common stock. Once converted into Class A common stock, the Class B common stock may not be reissued. The Company has reserved shares of its Class A common stock as follows: As of December 31, 2023 2022 2014 Stock Option and Grant Plan and 2021 Incentive Award Plan: Equity plan stock options outstanding 14,268,055 16,767,752 RSUs outstanding 11,301,279 9,914,125 Shares available for future issuance 18,260,813 16,774,634 2021 Employee Stock Purchase Plan: Shares available for future issuance 4,079,994 3,411,791 Total reserved shares 47,910,141 46,868,302 Equity Incentive Plans 2014 Stock Option and Grant Plan In December 2014, the Company adopted its 2014 Stock Option and Grant Plan (as amended, the “2014 Plan”), pursuant to which shares of the Company’s common stock were reserved for the issuance of stock options (incentive and non-statutory), restricted stock units (“RSUs”), and restricted stock to employees, directors, and consultants under terms and provisions established by the Company's board of directors and approved by the Company’s stockholders. The 2014 Plan was terminated in September 2021 in connection with the Direct Listing but continues to govern the terms of outstanding awards that were granted prior to the termination of the 2014 Plan. No further equity awards will be granted under the 2014 Plan. With the establishment of the 2021 Incentive Award Plan (the “2021 Plan”) as further discussed below, upon the expiration, forfeiture, cancellation, or reacquisition of any shares of Class A common stock underlying outstanding stock-based awards granted under the 2014 Plan, an equal number of shares of Class A common stock will become available for grant under the 2021 Plan. 2021 Incentive Award Plan In August 2021, the Company's board of directors adopted, and its stockholders approved, the 2021 Plan, which became effective in connection with the Direct Listing. The 2021 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, RSU awards, performance bonus awards, performance stock units, dividend equivalent awards and other forms of equity compensation (collectively, “equity awards”). As of December 31, 2023 , a total of 18,260,813 shares of the Company's Class A common stock have been reserved for issuance under the 2021 Plan in addition to (i) any shares available for issuance under the 2014 Plan as of the effective date of the 2021 Plan, (ii) the number of shares represented by awards outstanding under the Company's 2014 Plan (“Prior Plan Awards”) that become available upon the expiration, forfeiture, cancellation, or reacquisition of any shares of Class A common stock underlying outstanding stock awards granted under the 2014 Plan, and (iii) an annual increase on the first day of each fiscal year beginning in 2022 and ending in 2031, equal to the lesser of (A) 5% of the shares of the Company's common stock outstanding (on an as-converted basis) on the last day of the immediately preceding fiscal year and (B) such smaller number of shares of stock as determined by the Company's board of directors; provided, however, that no more than 88,000,000 shares of stock may be issued upon the exercise of incentive stock options. Stock Option Awards Stock options granted under the 2014 Plan and the 2021 Plan (collectively, the “combined stock plans”) generally vest based on continued service over four years . Option activity under the Company's combined stock plans is set forth below: Weighted Weighted average Aggregate Outstanding average remaining intrinsic stock exercise contractual value options price life (years) (in thousands) Balances as of December 31, 2022 16,767,752 $ 4.19 7.19 $ 132,298 Granted 425,352 11.94 Exercised ( 1,651,124 ) 2.80 Cancelled/forfeited ( 1,273,925 ) 6.32 Balances as of December 31, 2023 (1) 14,268,055 $ 4.40 6.27 $ 118,757 Exercisable as of December 31, 2023 (2) 12,494,164 $ 3.70 6.04 $ 112,726 (1) As no forfeitures are estimated due to the Company's adoption of ASU No. 2016-09, all options are vested or expected to vest. As of December 31, 2023 , no options were outstanding that were subject to a future performance condition (2) Exercisable shares include vested options as well as unvested shares that can be early exercised The aggregate intrinsic values of options are calculated as the difference between the exercise price of the options and the market price for shares of the Company’s Class A common stock as of each period-end. The total intrinsic value of options exercised for the years ended December 31, 2023, 2022, and 2021 was $ 16.4 million , $ 23.3 million , and $ 519.1 million, respectively. Stock options granted during the years ended December 31, 2023, 2022 , and 2021 had a weighted average grant date fair value of $ 6.69 , $ 8.27 , and $ 6.02 per share, respectively. The fair value is being expensed over the vesting period of the options on a straight-line basis as the services are being provided. No tax benefits were realized from options during the periods. As of December 31, 2023, total unrecognized stock-based compensation expense related to options outstanding under the combined stock plans was $ 11.0 million . This unrecognized expense as of December 31, 2023 is expected to be recognized over the weighted average remaining vesting period of 2.27 years. As of December 31, 2023, the Company had 342,000 shares of non-employee stock options outstanding under the combined stock plans. The fair value of each option granted to employees under the 2021 Plan is estimated on the grant date using the Black-Scholes pricing model. The following range of assumptions and data inputs were used in the Black-Scholes option-pricing model to estimate the fair value of the options granted under the 2021 Plan: Year Ended December 31, 2023 2022 2021 Fair value of common stock $ 11.37 - $ 12.37 $ 14.62 - $ 15.63 $ 63.52 Expected dividend yield — — — Risk-free interest rate 3.59 % - 4.36 % 3.01 % - 3.36 % 1.32 % Expected volatility 56.5 % - 56.8 % 55.3 % - 55.6 % 60.0 % Expected term (years) 5.5 - 6.0 6.0 - 6.3 6.3 Restricted Stock Units RSUs granted under the 2021 Plan generally vest based on continued service. RSUs granted pursuant to the 2014 Plan vest according to a service condition as well as a performance condition, through a liquidity event, including (i) a change in control of the Company or (ii) the initial public offering of the Company’s equity securities, following which the securities shall be publicly traded, which includes a direct listing. As a result of the Direct Listing, the performance condition for all RSUs granted pursuant to the 2014 Plan has been met. During the years ended December 31, 2023, 2022, and 2021, the Company recorded $ 77.1 million , $ 46.0 million , and $ 15.4 million in expense related to RSUs, respectively. The total fair value of RSUs vested during the years ended December 31, 2023, 2022, and 2021 was $ 56.3 million , $ 25.4 million , and $ 132.7 million , respectively. As of December 31, 2023, total unrecognized stock-based compensation expense related to RSUs was $ 149.6 million . This unrecognized expense as of December 31, 2023 is expected to be recognized over the weighted average remaining vesting period of 2.15 years. As of December 31, 2023, the Company had 159,521 shares of non-employee RSUs outstanding under the combined stock plans. RSU activity for the year ended December 31, 2023 was as follows: Restricted stock Weighted-average Balance as of December 31, 2022 9,914,125 $ 19.14 Granted 9,128,315 12.13 Vested ( 4,753,872 ) 17.07 Cancelled/forfeited ( 2,987,289 ) 17.57 Balance as of December 31, 2023 11,301,279 $ 14.76 2021 Employee Stock Purchase Plan In August 2021, the Company’s board of directors adopted, and its stockholders approved, the 2021 Employee Stock Purchase Plan (the “ESPP”), which became effective in connection with the Direct Listing. The ESPP authorizes the issuance of shares of Class A common stock pursuant to purchase rights granted to employees. As of December 31, 2023 , a total of 4,079,994 shares of the Company’s Class A common stock have been reserved for future issuance under the ESPP, in addition to any annual automatic evergreen increases in the number of shares of Class A common stock reserved for future issuance under the ESPP. The ESPP offers employees the option to purchase shares through a series of consecutive 12-month offering periods on each May 15th and November 15th (with two six-month purchase periods during each offering period). The price at which Class A common stock is purchased under the ESPP is equal to the lower of (i) 85 % of the closing trading price per share of the Company's Class A common stock on the first trading date of an offering period in which a participant is enrolled or (ii) 85 % of the closing trading price per share on the purchase date, which will occur on the last trading day of each purchase period, or such other price designated by the administrator. The initial offering period under the ESPP was longer than 12 months , commencing on September 28, 2021 and ending on November 14, 2022 . The first purchase period commenced on September 28, 2021 and ended on May 14, 2022. The ESPP offers a rollover feature pursuant to which, if the fair market value of a share of Class A common stock on the first purchase date is lower than the fair market value on the first trading day of the offering period, the respective offering period will terminate and each participant will be automatically enrolled in the offering period that commences immediately following the purchase date. In accordance with the rollover feature, immediately following the conclusion of each of the purchase periods since the initial purchase period on May 14, 2022 through the purchase period that ended on May 14, 2023, the corresponding offering periods were terminated and participants were automatically enrolled in a new 12-month offering period. The impact of the rollover feature did not result in material incremental compensation cost for the year ended December 31, 2023. The following assumptions were used to calculate the fair value of shares to be granted under the ESPP during the period utilizing the Black-Scholes option-pricing model: Year Ended December 31, 2023 2022 2021 Fair value of common stock $ 9.98 - $ 10.76 $ 14.77 - $ 17.04 $ 66.07 Expected dividend yield — — — Risk-free interest rate 4.75 % - 5.41 % 1.54 % - 4.63 % 0.10 % - 0.20 % Expected volatility 56.8 % - 60.0 % 60.0 % 60.0 % Expected term (years) 0.5 - 1.0 0.5 - 1.0 0.5 - 1.0 The expected term for the ESPP purchase rights is based on the duration of the offering period. Estimated volatility for ESPP purchase rights is based on the historical volatility of a group of industry peers as sufficient history is not available for our common stock. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time the ESPP purchase right was granted at the beginning of the offering period. The Company has not declared, nor does it expect to declare dividends. As of December 31, 2023 and 2022, 824,133 and 350,341 shares have been purchased under the ESPP, respectively. During the years ended December 31, 2023 and 2022, the Company recognized $ 2.4 million and $ 5.7 million , respectively, of stock-based compensation expense related to the ESPP. As of December 31, 2023, total unrecognized compensation costs related to the ESPP was $ 0.8 million , which will be amortized over a weighted average period of 0.55 years. Stock-based compensation expense, net of actual forfeitures is reflected in the consolidated statement of operations and comprehensive loss (in thousands): Year Ended December 31, 2023 2022 2021 Cost of revenue $ 7,300 $ 6,468 $ 1,951 Research and development 36,643 27,855 13,613 Sales and marketing 29,404 17,143 7,871 General and administrative 14,085 15,757 10,959 Restructuring and other related charges 853 — — Total stock-based compensation expense $ 88,285 $ 67,223 $ 34,394 |

Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforward. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to the taxable income or loss in the future years in which those temporary differences are expected to be recovered or settled. The effect on the deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established for deferred tax assets to the extent it is more likely than not that the deferred tax assets may not be realizable. The Company evaluates uncertain tax positions taken or expected to be taken in the course of preparing its tax return to determine whether the tax positions are more likely than not of being sustained upon challenge by the applicable taxing authority. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or remeasurement are reflected in the period in which the change in judgment occurs. At December 31, 2023 , the Company had approximately $ 434.5 million, $ 311.6 million, and $ 0.4 million of net operating loss carryforwards available to offset future federal, state, and foreign taxable income, respectively. If realized, none of the net operating loss carryforwards will be recognized as a benefit through additional paid-in capital. If not realized, federal carryforward losses of $ 25.4 million will expire beginning in 2032 and $ 409.1 million of carryforward losses will carryforward indefinitely. State carryforwards will expire beginning 2030 . The foreign losses can be carried forward indefinitely. At December 31, 2023 , the Company had tax credit carryforwards of $ 13.0 million and $ 11.7 million, net of reserves to offset future federal and state tax and $ 0.2 million of foreign research tax credit carryforwards. The carryforwards will expire in various amounts for federal purposes beginning 2033. The California R&D credits will not expire but the California competes tax credits will expire beginning 2026. The foreign research tax credits are allowed a carryforward of 20 years and are set to expire in 2042. Utilization of net operating loss carryforwards and credits may be subject to substantial annual limitation due to ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitations may result in the expiration of the net operating losses before utilization. As of December 31, 2023 , the Company had unrecognized income tax benefits of $ 5.1 million. The increase in the Company’s unrecognized tax benefit was primarily attributable to current year credit activities. A reconciliation of the beginning and ending amount of unrealized tax benefit (excluding interest and penalties) is as follows (in thousands): Year Ended December 31, 2023 2022 2021 Beginning balance $ 3,625 $ 2,253 $ 1,226 Increases related to tax positions taken during a prior year — — — Decreases related to tax positions taken during a prior year — — — Increases related to tax positions taken during the current year 1,493 1,372 1,027 Ending balance $ 5,118 $ 3,625 $ 2,253 The total unrecognized tax benefit, if recognized, would not affect the Company’s effective tax rate as the tax benefit would increase the deferred tax asset, which is currently offset with a full valuation allowance. The Company does not anticipate that the amount of existing unrecognized tax benefit will significantly increase or decrease within the next 12 months. Accrued interest and penalties related to the unrecognized tax benefits are recorded in income tax expense. No interest, penalties, or tax benefits were recognized during the year ended December 31, 2023. The Company files U.S. federal, Netherlands, United Kingdom, France, Singapore, Japan, Germany, Canada, India, and Australia income tax returns as well as state income tax returns for various state jurisdictions. Due to the Company’s net operating loss carryforwards in the United States, its income tax returns remain subject to federal and state tax authorities for all prior years. There are no tax years under examination by any jurisdiction, except India, at this time. The Company records liabilities related to uncertain tax positions and believes that it has provided adequate reserves for income tax uncertainties in all open tax years. The Company provides for U.S. federal income taxes on the earnings of foreign subsidiaries unless they are considered permanently reinvested outside of the U.S. As of December 31, 2023 , the Company’s management asserted that it is their intent to indefinitely reinvest unremitted foreign earnings for all its foreign entities. |

Commitments and Contingencies | (9) Commitments and Contingencies Legal Matters The Company is involved in various legal and regulatory matters arising from the normal course of business activities. For example, on February 14, 2024, a putative securities class action (the “Putative Class Action”) was filed in the United States District Court for the Northern District of California captioned Fagan v. Amplitude, Inc., et al., Case No. 3:24-cv-00898, naming us, our Chief Executive Officer, and former Chief Financial Officer as defendants. The lawsuit is purportedly brought on behalf of all those who purchased or acquired our common stock between September 21, 2021 and February 16, 2022. The complaint alleges claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 based on allegedly false or misleading statements related to our business and financial outlook. The lawsuit seeks unspecified damages and other relief. The defendants intend to deny the allegations of wrongdoing and vigorously defend against the claims in the Putative Class Action. We have received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to defend ourselves, our partners and our customers by determining the scope, enforceability and validity of third-party proprietary rights, or to establish our proprietary rights. In addition to the matters discussed above, from time to time, we are party to litigation and other legal proceedings in the ordinary course of business. While we do not believe the ultimate resolution of pending legal matters is likely to have a material adverse effect on our financial position, the results of any litigation or other legal proceedings are uncertain and as such the resolution of such legal proceedings, either individually or in the aggregate, could have a material adverse effect on our business, results of operations, financial condition or cash flows. The Company records litigation accruals for legal matters, which are both probable and estimable. For legal proceedings for which there is a reasonable possibility of loss (meaning those losses for which the likelihood is more than remote but less than probable), the Company has determined that it does not have material exposure, or it is unable to develop a range of reasonably possible losses. Although no assurance may be given, the Company believes that it is not presently a party to any litigation of which the outcome, if determined adversely, would individually or in the aggregate be reasonably expected to have a material and adverse effect on the business, operating results, cash flows, or financial position. Legal fees are expensed in the period in which they are incurred. |

These estimates are based on information available as of the date of the financial statements and may involve subjective or significant judgment by the Company; therefore, actual results could differ from the Company’s estimates. Items subject to such estimates and assumptions include, but are not limited to the: • expected period of benefit for deferred commissions; • useful lives of long-lived assets; • valuation of goodwill and intangible assets; • recognition, measurement, and valuation of deferred tax assets and income tax uncertainties; and • incremental borrowing rates used for operating leases. |
Revenue Recognition | Revenue Recognition The Company derives revenue primarily from sales of subscription services. Revenue is recognized when, or as, the related performance obligation is satisfied by transferring the control of the promised service to a customer. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these services. To achieve the core principle of the revenue standard, the Company applies the following steps: (i) Identification of the contract, or contracts, with the customer The Company considers the terms and conditions of the contract in identifying the contracts. The Company determines a contract with a customer to exist when the contract is approved, each party’s rights regarding the services to be transferred can be identified, the payment terms for the services can be identified, it has been determined the customer has the ability and intent to pay, and the contract has commercial substance. At contract inception, the Company will evaluate whether two or more contracts should be combined and accounted for as a single contract and whether the combined or single contract includes more than one performance obligation. The Company applies judgment in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit, and financial information pertaining to the customer. (ii) Identification of the performance obligations in the contract Performance obligations promised in a contract are identified based on the services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the service either on its own or together with other resources that are readily available from third parties or from the Company and are distinct in the context of the contract, whereby the transfer of the services and the products is separately identifiable from other promises in the contract. The Company’s performance obligations consist of (1) core subscription services and (2) professional and other services. (iii) Determination of the transaction price The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring services to the customer. The transaction price includes SaaS subscription fees based on the contracted usage as well as variable consideration associated with overage fees on exceeded volume limits. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of the Company’s contracts contain a significant financing component. (iv) Allocation of the transaction price to the performance obligations in the contract Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on each performance obligation’s relative standalone selling price. Contracts typically have one performance obligation of providing access to the core subscription service. On occasion, contracts include professional services to customers, which are separate performance obligations. Professional services revenue has historically not been significant. (v) Recognition of the revenue when, or as, a performance obligation is satisfied Revenue is recognized at the time the related performance obligation is satisfied by transferring the control of the promised service to a customer. For subscription services, revenue is recognized as the customer is given access to the core subscription service, in an amount that reflects the consideration that the Company expects to receive in exchange for access to the services. With respect to professional services, the Company recognizes revenue as services are delivered. The Company generates all its revenue from contracts with customers. Subscription revenue The Company generates revenue from subscription services including SaaS subscriptions and customer support services subject to contractual subscription terms. SaaS subscriptions enable customers to access and send event volume data to the Company’s cloud-based platform. Subscription arrangements with customers do not provide the customer with the right to take possession of the Company’s software at any time. Instead, customers are granted continuous access to the platform over the contractual period. A time-elapsed method is used to measure progress because the Company’s obligation is to provide continuous service over the contractual period and control is transferred evenly over the contractual period. Accordingly, the fixed consideration related to subscription revenue is recognized ratably over the contract term beginning on the date access to the subscription product is provisioned. The typical subscription term is 12 months with various payment terms ranging from monthly to annual up-front payments. Most contracts are non-cancellable over the contractual term and are subject to standard terms and conditions; however, certain contracts contain nonstandard terms that may impact the timing of revenue recognition. Some customers have the option to purchase additional subscription services at a stated price. These options are evaluated on a case-by-case basis but generally do not provide a material right as they do not provide a discount to the customer that is incremental to the range of discounts typically given for the same services that are sold to a similar class of customers, even when the stand-alone selling price of the services subject to the option is highly variable. Remaining performance obligations The Company’s contracts with customers generally include one combined performance obligation, its core subscription offering, which is a series of distinct services transferred to the customer ratably over the respective obligation’s term. Other performance obligations that may be identified in contracts include professional services. As of December 31, 2023, the unrecognized transaction price related to remaining performance obligations was $ 239.4 million . The Company’s remaining performance obligations as of December 31, 2023 are expected to be recognized as follows (in thousands): As of December 31, 2023 2022 Less than or equal to 12 months $ 188,456 $ 190,595 Greater than 12 months 50,962 57,581 Total remaining performance obligations $ 239,418 $ 248,176 |
Disaggregation of Revenue | Disaggregation of Revenue The following table shows the Company’s disaggregation of revenue by geographic areas, as determined based on the address of the Company's customers (in thousands): Year Ended 2023 2022 2021 United States $ 167,919 $ 146,415 $ 107,244 International 108,365 91,652 60,017 Total revenue $ 276,284 $ 238,067 $ 167,261 |
Accounts Receivable, Net | Accounts Receivable, Net Accounts receivable are primarily comprised of cash due from customers and are recorded at the invoiced amount, net of an allowance for doubtful accounts. The Company has a well-established collections history from its customers. Credit is extended to customers based on an evaluation of their financial condition and other factors. In determining the necessary allowance for doubtful accounts, the Company estimates the lifetime expected credit losses against the existing accounts receivable balance. The Company's estimate is based on certain factors including historical loss rates, current economic conditions, reasonable and supportable forecasts, and customer-specific circumstances. The Company maintained an allowance of $ 1.1 million and $ 0.7 million for doubtful accounts as of December 31, 2023 and 2022 , respectively. The movements in the allowance for doubtful accounts were not material for any of the periods presented. The Company does not have any off-balance-sheet credit exposure related to its customers. |
Concentration of Risk and Significant Customers | Concentration of Risk and Significant Customers Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, marketable securities, and accounts receivable. Although the Company deposits its cash with high-quality, credit-rated financial institutions, the deposits, at times, may exceed federally insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. No customer accounted for 10 % or more of total revenue for the years ended December 31, 2023, 2022, and 2021. As of the year ended December 31, 2023, o ne customer represented 10 % of accounts receivable. As of the year end December 31, 2022 no customers represented 10 % or more of accounts receivable. |
Deferred Revenue | Deferred Revenue Deferred revenue consists of billings of payments received in advance of revenue recognition and is recognized when, or as, performance obligations are satisfied. The Company generally invoices its customers annually or in semi-annual, quarterly, or monthly installments. Accordingly, the deferred revenue balance does not represent the total contract value of annual non-cancellable subscription agreements. The amount of revenue recognized in the years ended December 31, 2023 and 2022 that was included in deferred revenue at the beginning of the period was $ 89.6 million and $ 68.8 million, respectively. |
Deferred Commissions | Deferred Commissions The Company capitalizes sales commissions that are recoverable and incremental due to the acquisition of customer contracts. The Company determines whether costs should be deferred based on its sales compensation plans, if the commissions are in fact incremental and would not have occurred absent the customer contract. Commissions paid upon the initial acquisition of a contract are deferred and then amortized on a straight-line basis over a period of benefit, determined to be five years. The period of benefit is estimated by considering factors such as the expected life of our subscription contracts, historical customer attrition rates, technological life of our platform, as well as other factors. Sales commissions for renewal of a subscription contract are not considered commensurate with the commissions paid for the acquisition of the initial subscription contract given the substantive difference in commission rates between new and renewal contracts. The Company determines the period of benefit for renewal subscription contracts by considering the contractual term for renewal contracts. Amounts anticipated to be recognized within 12 months of the balance sheet date are recorded as deferred commissions, current, with the remaining portion recorded as deferred commissions, noncurrent, in the consolidated balance sheets. Amortization of deferred commissions is included in sales and marketing expense in the consolidated statement of operations and comprehensive loss. The Company periodically reviews these deferred commissions to determine whether events or changes in circumstances have occurred that could impact recoverability or the period of benefit. There were no impairment losses recorded during the periods presented. The following table represents a roll-forward of the Company’s deferred commissions as of December 31, 2023 and 2022 (in thousands): Year Ended 2023 2022 Beginning balance $ 36,717 $ 28,685 Additions to deferred commissions 13,656 17,740 Amortization of deferred commissions ( 11,987 ) ( 9,708 ) Ending balance 38,386 36,717 Deferred commissions, current portion 11,444 10,918 Deferred commissions, net of current portion 26,942 25,799 Total deferred commissions $ 38,386 $ 36,717 |
Cost of Revenue | Cost of Revenue Cost of revenue primarily consists of costs related to third-party hosting costs; employee-related expenses, including salaries, stock-based compensation and benefits for operations and support personnel; software license fees; certain developed technology and acquired developed software amortization; and allocated overhead. |
Research and Development Expense | Research and Development Expense The Company’s costs related to research, design, maintenance, and minor enhancements of the Company’s platform are expensed as incurred. These costs consist primarily of personnel-related expenses, including stock-based compensation and allocated overhead costs, contractor and consulting fees related to the design, development, testing, and enhancements of the Company’s platform, and software, hardware, and cloud infrastructure fees for staging and development related to research and development activities necessary to support growth in the Company’s employee base and in the adoption of its platform. |
Advertising Costs | Advertising Costs The Company expenses all advertising costs as incurred as a component of sales and marketing expenses. Advertising expenses of $ 5.5 million , $ 5.8 million , and $ 4.5 million were incurred during the years ended December 31, 2023, 2022 , and 2021, respectively. |
Share-Based Compensation | Stock-Based Compensation The Company records stock-based compensation expense for all stock-based awards, including stock options, restricted stock units (“RSUs”) and purchase rights issued under the 2021 Employee Stock Purchase Plan (“ESPP”), made to employees, non-employees, and directors based on estimated fair values recognized over the requisite service period. The Company measures and recognizes compensation expense for all stock-based payment awards granted to employees, directors, and non-employees based on the estimated fair values on the date of the grant and vesting criteria. For options, vesting is typically over a four-year period and is contingent upon continued employment on each vesting date. In general, options granted to newly hired employees vest ratably each month over a 36-month period to 48-month period. RSUs typically vest ratably each quarter over a three-year period and is contingent upon continued employment on each vesting date. The Company recognizes compensation expense for service-based stock-based awards as an expense over the employee’s or director’s requisite service period on a straight-line basis. The Company also has certain options and awards that have performance-based vesting conditions upon certain liquidity events. As a result of the Direct Listing, the liquidity event was met for all outstanding awards with a performance condition and therefore the related expense was recognized using the accelerated attribution method. Forfeitures are accounted for as they occur. Stock-based compensation expense is allocated to cost of revenue and operating expenses on the consolidated statements of operations and comprehensive loss based on where the associated employee’s functional department is located. The fair value of stock options granted under the 2021 Plan and purchase rights issued under the ESPP for purposes of calculating stock-based compensation expense is estimated on the grant date using the Black-Scholes pricing model. The Black-Scholes pricing model requires the Company to make assumptions and judgments about the inputs used in the calculation, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the volatility of the Company’s common stock, risk-free interest rate, and expected dividend yield. The expected term represents the period that the Company’s stock-based awards are expected to be outstanding. For stock options considered to be “plain vanilla” options, the Company estimates the expected term based on the simplified method, which is essentially the weighted average of the vesting period and contractual term, as the Company's historical option exercise experience does not provide a reasonable basis upon which to estimate the expected term. The volatility is based on an average of the historical volatilities of the common stock of comparable public companies with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option or purchase right. The Company’s expected dividend yield input is zero as it has not historically paid, nor does it expect in the future to pay, cash dividends on its common stock. Stock-based compensation expense for RSUs granted under the 2021 Plan is measured based on the fair value of the underlying shares on the date of grant. |
Taxes | Taxes Income taxes are accounted for under the asset-and-liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income or loss in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established for deferred tax assets to the extent it is more likely than not that the deferred tax assets may not be realized. The Company evaluates uncertain tax positions taken or expected to be taken in the course of preparing its tax return to determine whether the tax positions are more likely than not of being sustained upon challenge by the applicable tax authority. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. |
Cash, Cash Equivalents, and Restricted Cash | Cash, Cash Equivalents, and Restricted Cash The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents are stated at fair value. Restricted cash represents cash held to collateralize lease obligations related to the Company's property leases. As of December 31, 2023 and 2022, $ 0.9 million of restricted cash is recorded as noncurrent assets. T he following table represents the Company's cash, cash equivalents, and restricted cash at each period end (in thousands): As of December 31, 2023 2022 Cash and cash equivalents $ 248,491 $ 218,494 Restricted cash, noncurrent 869 855 Total cash, cash equivalents, and restricted cash $ 249,360 $ 219,349 |
Investments in Marketable Securities | Investments in Marketable Securities Investments in marketable securities consist of commercial paper, corporate notes, and bonds, as well as U.S. Treasury and government agency securities. Management determines the appropriate classification of investments at the time of purchase and reevaluates such determination at each balance sheet date. Marketable securities are classified as available-for-sale and are carried at fair value in the consolidated balance sheets and are classified as short-term or long-term based on their remaining contractual maturities. The Company evaluates its investments with unrealized loss positions at the individual security level to determine whether the unrealized loss was related to credit or noncredit factors. The Company considers whether a credit loss exists based on the extent of the unrealized loss position, any adverse conditions specifically related to the security or the issuer's operating environment, pay structure of the security, the issuer's payment history and any changes in the issuer's credit rating. Estimated credit losses are determined using a discounted cash flow model and recorded as an allowance, with changes in expected credit losses on the Company's investments recorded in “Other income (expense), net” in the consolidated statements of operations and comprehensive loss. Unrealized gains and losses related to noncredit factors are reflected in “Accumulated other comprehensive loss” on the consolidated balance sheets. |
Fair Value Measurement | Fair Value Measurements The Company determines fair value based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. These levels are: Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date for assets or liabilities; the fair value hierarchy gives the highest priority to Level 1 inputs. Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date; the fair value hierarchy gives the lowest priority to Level 3 inputs. Observable inputs are based on market data obtained from independent sources. The fair value of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued liabilities approximated their carrying values as of December 31, 2023 and 2022 due to their short-term nature. The fair values of all of these instruments are categorized as Level 1 in the fair value hierarchy. The fair value of the Company's marketable securities as categorized by the fair value level hierarchy is detailed in Note 3. |
Business Combinations | Business Combinations The Company applies a screen test to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets to determine whether a transaction is accounted for as an asset acquisition or business combination. When the Company acquires a business, the purchase consideration is allocated to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated respective fair value based on the acquisition method of accounting. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, particularly to acquired intangible assets. These assumptions include, but are not limited to, reproduction costs and appropriate discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Acquisition costs, such as legal and consulting fees, are expensed as incurred. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the consolidated statement of operations and comprehensive loss. |
Goodwill and Other Acquired Intangible Assets | Goodwill and Other Acquired Intangible Assets Goodwill represents the excess of the purchase price over the fair value of net assets acquired in connection with business combinations accounted for using the acquisition method of accounting. The Company has one reporting unit and performs testing of goodwill in the fourth quarter of each year, or as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. These triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows. The Company’s test for goodwill impairment starts with a qualitative assessment to determine whether it is necessary to perform the quantitative goodwill impairment test. If the Company determines, based on the qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, then a quantitative goodwill impairment test is required. There were no impairments of goodwill recorded for the years ended December 31, 2023, 2022, and 2021. Intangible assets mainly consist of developed technology resulting from the Company’s acquisitions. Acquired intangible assets are recorded at cost, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives, which was determined to be three years for all acquired intangibles. For developed technology, amortization costs were included within cost of revenue in the consolidated statements of operations upon the related product release date. Long-lived assets, including intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. There was no impairment of intangible assets recorded for the years ended December 31, 2023, 2022 , and 2021. |
Property and Equipment, Net | Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated on a straight-line basis over the estimated useful lives of those assets, as follows: Property Useful Life Office equipment 3 years Furniture and fixtures 3 years Leasehold improvements Shorter of remaining lease term or 5 years Software including internal-use software 3 years Maintenance and repairs are charged to expense as incurred and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation is removed from the accounts and any resulting gain or loss is reflected in the statements of operations and comprehensive loss for the period realized. |
Operating Leases | Operating Leases The Company determines if an arrangement is, or contains, a lease at inception. Leases arise from contractual obligations that convey the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company determines whether an arrangement is or contains a lease at inception, based on whether there is an identified asset and whether the Company controls the use of the identified asset throughout the period of use. At lease commencement date, the Company determines lease classification between finance and operating, allocates the consideration to the lease and non-lease components and recognizes a right-of-use (“ROU”) asset and corresponding lease liability for each lease component. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments based on the lease contracts. Operating lease ROU assets and liabilities were recognized at adoption date or lease commencement date, based on the present value of lease payments over the remaining lease term. The Company’s lease contracts do not provide an implicit rate, as such the Company used its incremental borrowing rate based on the information available at adoption date or lease commencement date, if the commencement date was after January 1, 2022, in determining the present value of lease payments. The operating lease ROU assets also include any lease payments made to the lessors at or before the lease commencement date, and excludes lease incentives. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The lease liability is initially measured as the present value of the remaining lease payments over the lease term. The discount rate used to determine the present value is the Company's incremental borrowing rate unless the interest rate implicit in the lease is readily determinable. The Company estimates the incremental borrowing rate based on the information available at lease commencement date for borrowings with a similar term. The ROU asset is initially measured as the present value of the lease payments, adjusted for initial direct costs, prepaid lease payments to lessors and lease incentives. The operating lease right-of-use assets and liabilities recognized at January 1, 2022, the adoption date, were based on the present value of lease payments over the remaining lease term as of that date, using the incremental borrowing rate as of that date. The Company elected the practical expedients to not recognize right-of-use assets and liabilities for leases with a term of less than twelve months and to not separate non-lease components from the associated lease components for the Company's office leases and certain other asset classes. The total consideration includes fixed payments and contractual escalation provisions. The Company is responsible for maintenance, insurance, property taxes and other variable payments, which are expensed as incurred. The Company's leases include options to renew or terminate. The Company includes the option to renew or terminate in the determination of the lease term when the option is deemed to be reasonably certain that the Company will exercise that option. The Company accounts for changes in the expected lease term as a modification of the original contract. Operating leases are classified in “Operating lease right-of-use assets” and “Operating lease liabilities, noncurrent” on the Company's consolidated balance sheets. The current balance of the operating lease liabilities is included within “Accrued expenses” on the Company's consolidated balance sheets. Operating lease expense is recognized on a straight-line basis over the expected lease term and included in “Operating expenses” in the Company's consolidated statements of operations and comprehensive loss. |
Capitalized Internal-Use Software Costs | Capitalized Internal-Use Software Costs The Company capitalizes development costs related to its platform and certain other projects for internal use. The Company considered the guidance set forth in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Subtopic 350-40-15, Accounting for the Cost of Computer Software Developed or Obtained for Internal Use , which requires companies to capitalize qualifying computer software costs that are incurred during the application development stage, and then amortize them over the software’s estimated useful life. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Capitalized internal-use software costs are included in “Property and equipment, net” on the Company's consolidated balance sheets and are amortized on a straight-line basis over its estimated useful life into cost of revenue within the consolidated statements of operations and comprehensive loss. All software development costs prior to capitalization have been recorded in research and development expense in the consolidated statements of operations. There was no impairment to capitalized internal-use software costs during the years ended December 31, 2023, 2022 , and 2021. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company evaluates long-lived assets or asset groups for impairment whenever events indicate that the carrying value of an asset or asset group may not be recoverable based on expected future cash flows attributable to that asset or asset group. Recoverability of assets held and used is measured by comparison of the carrying amount of an asset or an asset group to estimated undiscounted future net cash flows expected to be generated by the asset or asset group. If the carrying amount of an asset or asset group exceeds estimated undiscounted future cash flows, then an impairment charge would be recognized based on the excess of the carrying amount of the asset or asset group over its fair value. No impairment loss on long-lived assets was recognized in the years ended December 31, 2023, 2022 , and 2021. |
Net Loss Per Share | Net Loss Per Share Basic net loss per share attributable to the Company’s common stockholders is computed in conformity with the two-class method required for participating securities. The rights, including the liquidation and dividend rights, of the holders of Class A and Class B common stock are identical, except with respect to voting, conversion, and transfer rights. As the liquidation and dividend rights are identical, all undistributed earnings are allocated on a proportionate basis to each class of common stock and the resulting basic and diluted net loss per share attributable to common stockholders are, therefore, the same for both Class A and Class B common stock on both an individual and a combined basis. Basic net loss per share is computed by dividing the net loss attributable to the Company’s common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is the same as basic net loss per share for all periods presented because the effects of potentially dilutive items were anti-dilutive given the Company’s net loss position in each period presented. |
Indemnifications and Warranties | Indemnifications The Company delivers its applications over the internet as a subscription service using a SaaS model. Each subscription is subject to the terms of the contractual arrangement with the customer and often includes certain provisions for holding the customer harmless against and indemnifying the customer from costs, damages, losses, liabilities, and expenses arising from claims that the Company’s software infringes upon a copyright, trademark, or other trade secret rights, and third-party claims arising from the Company’s breach of the contract. Customers also indemnify the Company for claims relating their improper use of the service or intellectual property claims originating from customer actions or content. The Company has not incurred any expense in defense or reimbursement of any of its customers for losses related to indemnification provisions, and no material claims against the Company are outstanding as of December 31, 2023, 2022 , and 2021. The Company’s exposure under these indemnification provisions is often capped at a fixed amount in many customer agreements and uncapped in others. Due primarily to the lack of history of prior indemnification claims and the unique facts and circumstances involved in each particular contractual arrangement, the Company has determined that potential costs related to indemnification are not probable or estimable and, as such, has no t recorded a reserve for the years ended December 31, 2023 and 2022. In addition, in the ordinary course of business, the Company may provide indemnifications of varying scope and terms to vendors, directors, officers, and other parties with respect to certain matters. The Company has not incurred any material costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in its consolidated financial statements. Warranties For certain customers, the Company provides a performance warranty for accessibility to the Company’s platform as identified in an order form during the order duration. The Company’s software products are generally warranted for certain customers to substantially conform to the specifications set forth in the related customer contract and published documentation. In the event there is a failure of such warranties, the Company generally will correct the problem or provide a reasonable workaround or replacement product. The Company has the standard 30-day cure period for failures that amount to a material breach, and no warranted time frame for nonmaterial failures. If the Company cannot correct or provide a workaround or replacement product for material failures within the cure period, then the customer’s remedy is generally limited to termination of the contractual arrangement related to the nonconforming product services with a pro rata refund of the related fees paid. The Company has not incurred significant expense under these service warranties, nor does it expect that any future expense is probable. Accordingly, the Company has determined that potential costs related to warranties are not probable or estimable and, as such, has no t recorded a reserve as of December 31, 2023 and 2022 . |
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements The Company did not adopt accounting pronouncements during the year ended December 31, 2023. |
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements Income Taxes: In December 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The amendment in the ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this ASU are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of the new standard on its consolidated financial statements which is expected to result in enhanced disclosures |
