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 companies analyze their customer behavior within 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 Note 2 below. Basis of Presentation and Principles of Consolidation The condensed 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. 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. The unaudited condensed consolidated balance sheet as of December 31, 2021 included herein was derived from the audited financial statements as of that date, but does not include all disclosures, including certain notes required by U.S. GAAP on an annual reporting basis. In management's opinion, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to state fairly the balance sheet, statements of operations and comprehensive loss, statements of redeemable convertible preferred stock and stockholders' equity (deficit), and statements of cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year or any future period. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”) . Reclassification Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period condensed consolidated financial statements. 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 condensed 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 the Company’s common stock and stock-based awards for periods prior to the direct listing of the Company's Class A common stock on the Nasdaq Capital Market (the “Direct Listing”); • valuation of goodwill and intangible assets; • recognition, measurement, and valuation of deferred tax assets and income tax uncertainties; and • incremental borrowing rate used for operating leases. Risks and Uncertainties While the duration and extent of the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the extent and effectiveness of containment actions, it has already had an adverse effect on the global economy and the lasting effects of the pandemic continue to be unknown. The Company may experience customer losses, including due to bankruptcy or customers ceasing operations, which may result in delays in collections or an inability to collect accounts receivable from these customers. The extent to which COVID-19 may continue to impact the Company’s financial condition, results of operations, or liquidity continues to remain uncertain, and as of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or an adjustment to the carrying value of the Company’s assets or liabilities. These estimates may change, as new events occur and additional information is obtained, which will be recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates, and any such differences may be material to the Company’s financial statements. 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 three and nine months ended September 30, 2022 and 2021. As of the quarter ended September 30, 2022 , one customer represented 17 % of accounts receivable. As of the year ended December 31, 2021, one customer represented 10 % of accounts receivable. Significant Accounting Policies The Company's significant accounting policies are described in the 2021 Form 10-K. There have been no significant changes to these policies that have had a material impact on the Company's condensed consolidated financial statements and related notes for the nine months ended September 30, 2022 other than for the adoption of new accounting guidance related to leases effective January 1, 2022 further described below. 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, if the commencement date was after January 1, 2022, 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 condensed consolidated balance sheets. The current balance of the operating lease liabilities is included within “Accrued expenses” on the Company's condensed 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 condensed consolidated statements of operations and comprehensive loss. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) , which requires companies to recognize lease liabilities and corresponding right-of-use leased assets on the balance sheets and to disclose key information about leasing arrangements. Qualitative and quantitative disclosures will be enhanced to better understand the amount, timing, and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for annual periods beginning after December 15, 2021, with early adoption permitted. Additionally, in 2018 and 2019, the FASB issued the following Topic 842–related ASUs: • 2018-01, Land Easement Practical Expedient for Transition to Topic 842 , which clarifies the applicability of Topic 842 to land easements and provides an optional transition practical expedient for existing land easements; • 2018-10, Codification Improvements to Topic 842, Leases , which makes certain technical corrections to Topic 842; • 2018-11, Leases (Topic 842): Targeted Improvements , which allows companies to adopt Topic 842 without revising comparative period reporting or disclosures and provides an optional practical expedient to lessors to not separate lease and non-lease components of a contract if certain criteria are met; and • 2019-01, Leases (Topic 842): Codification Improvements , which provides guidance for certain lessors on determining the fair value of an underlying asset in a lease and on the cash flow statement presentation of lease payments received; ASU No. 2019-01 also clarifies disclosures required in interim periods after adoption of ASU No. 2016-02 in the year of adoption. The Company adopted the new standard as of January 1, 2022, and recognized a cumulative-effect adjustment to the opening balance of accumulated deficit as of adoption date. The Company elected the optional transition approach to not apply Topic 842 in the comparative periods presented. The Company elected the relief package of practical expedients to not reassess whether existing contracts contain leases, the lease term and classification for existing leases and whether existing initial direct costs meet the new definition. The adoption of Topic 842 resulted in the recognition of total right-of-use of $11.6 million and total lease liabilities of $13.2 million as of the date of adoption. Additionally, the Company has derecognized $1.6 million in deferred rent upon adoption of this standard. The adoption of Topic 842 did not have a material impact to the condensed consolidated statements of operations and comprehensive loss or statements of cash flows. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350) , which eliminates Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on today’s Step 1). This update is effective for annual and interim impairment tests performed in periods beginning after December 15, 2022. The Company early adopted the standard as of January 1, 2022. The adoption of ASC 350 did not have a material impact to the condensed consolidated financial statements. Recently Issued Accounting Pronouncements Financial Instruments - Credit Losses: In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments (Topic 326). This standard revises current U.S. GAAP methodology by requiring measurement and immediate recognition of expected credit losses on in-scope financial instruments, including trade receivables. ASU No. 2016-13 is effective for annual periods beginning after December 15, 2022, with early adoption permitted in fiscal years beginning after December 31, 2018. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements.

Equity [Abstract]
Stockholders' Equity (Deficit) and Equity Incentive Plans	(6) Stockholders’ Equity (Deficit) 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 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 condensed 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 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 common stock as follows: As of As of 2014 Stock Option and Grant Plan and 2021 Incentive Award Plan: Equity plan stock options outstanding 17,398,329 21,214,155 RSUs outstanding 9,086,234 1,716,614 Shares available for future issuance 17,891,146 19,005,008 2021 Employee Stock Purchase Plan: Shares available for future issuance 3,585,845 2,663,371 Total reserved shares 47,961,554 44,599,148 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 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”). A total of 18,643,596 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 . Options issued outside of the combined stock plans were immaterial and therefore not discussed further below. Option activity under the Company's combined stock plans for the nine months ended September 30, 2022 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, 2021 21,214,155 $ 4.15 8.12 $ 1,035,039 Granted 858,630 14.84 Exercised ( 2,239,714 ) 2.77 Cancelled/forfeited ( 2,434,742 ) 8.72 Balances as of September 30, 2022 (1) 17,398,329 $ 4.22 7.45 $ 195,745 Exercisable as of September 30, 2022 (2) 12,671,705 $ 3.19 7.09 $ 155,554 (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 September 30, 2022, 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 During December 2020, the Company granted 1,756,545 stock options to two executives which contain both a service condition and a performance condition. Based on the terms of the options, the vesting commencement date is defined as the date on which a registration statement on Form S-1 filed with the SEC becomes effective (a “QPO Event”). In conjunction with the Direct Listing, a QPO Event occurred and therefore the options began to vest 1/24th each month subsequent to September 21, 2021. During the three and nine months ended September 30, 2022, the Company recognized $ 0.3 million and $ 1.2 million in stock-based compensation expense related to these awards using the accelerated attribution method, respectively. The unrecognized stock-based compensation expense was $ 0.5 million and $ 1.7 million as of September 30, 2022 and December 31, 2021, respectively. 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 common stock as of each period-end. The total intrinsic value of options exercised for the nine months ended September 30, 2022 and 2021 was $ 28.4 million and $ 420.9 million , respectively. Stock options granted during the nine months ended September 30, 2022 and 2021 had a weighted average grant date fair value of $ 8.27 and $ 5.67 pe r share, respectively. With the exception of the performance options detailed above, the fair value is being expensed over the vesting period of the options on a straight-line basis as the services are being provided. The total grant date fair value of shares vested during the nine months ended September 30, 2022 and 2021 was $ 14.0 million and $ 6.4 million , respectively. No tax benefits were realized from options during the periods. As of September 30, 2022, total unrecognized stock-based compensation expense related to options outstanding under the combined stock plans was $ 26.4 million . This unrecognized expense as of September 30, 2022 is expected to be recognized over the weighted average remaining vesting period of 2.00 ye ars. As of September 30, 2022, the Company had 354,500 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. Based on the nature of the underlying options granted under the 2014 Plan, the fair value of each option granted to employees is estimated on the date of grant using the Monte Carlo simulation model. The following range of assumptions and data inputs were used in the Black-Scholes option-pricing model to estimate the fair value of options granted under the 2021 Plan: Nine Months Ended Fair value of common stock $ 14.62 - $ 15.63 Expected dividend yield — Risk-free interest rate 3.01 % - 3.36 % Expected volatility 55.3 % - 55.6 % Expected term (years) 6.0 - 6.3 Restricted Stock Units RSUs granted under the 2021 Plan generally vest based on continued service, typically over a three- to four-year period. 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 three and nine months ended September 30, 2022, the Company recorded $ 13.5 million and $ 29.8 million in stock-based compensation expense related to RSUs, respectively. During the three and nine months ended September 30, 2021, the Company recorded $ 7.2 million in stock-based compensation expense related to RSUs. As of September 30, 2022, total unrecognized stock-based compensation expense related to RSUs was $ 165.4 million . This unrecognized expense as of September 30, 2022 is expected to be recognized over the weighted average remaining vesting period of 2.95 years. As of September 30, 2022, the Company had 248,027 sha res of non-employee RSUs outstanding under the combined stock plans. RSU activity during the nine months ended September 30, 2022 was as follows: Restricted stock Weighted-average Balance as of December 31, 2021 1,716,614 $ 38.40 Granted 8,955,958 18.19 Vested ( 821,063 ) 23.42 Cancelled/forfeited ( 765,275 ) 30.62 Balance as of September 30, 2022 9,086,234 $ 24.80 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 common stock pursuant to purchase rights granted to employees. A total of 3,585,845 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 will be 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 the first purchase period on May 14, 2022, the initial offering period was terminated and participants were automatically enrolled in a new 12-month offering period commencing on May 15, 2022 and ending on May 14, 2023. The impact of the rollover feature did not result in any incremental compensation cost for the three or nine months ended September 30, 2022. As of September 30, 2022, 0.2 million shares have been purchased under the ESPP. During the nine months ended September 30, 2022, the Company recognized $ 4.5 million of stock-based compensation expense related to the ESPP and withheld $ 5.3 million in contributions from employees. As of September 30, 2022, total unrecognized compensation cost related to the ESPP was $ 1.9 million , which will be amortized over a weighted average period of 0.62 years.

Income Taxes	(7) Income Taxes The Company had an effective tax rate of 0.9 % and ( 0.6 )% for the three and nine months ended September 30, 2022, respectively, and 0.2 % and ( 1.1 )% for the three and nine months ended September 30, 2021, respectively. The Company continues to incur U.S. operating losses and has minimal profits in its foreign jurisdictions. During the three and nine months ended September 30, 2022 and 2021, the Company has evaluated all available evidence, both positive and negative, including historical levels of income, and expectations and risks associated with estimates of future taxable income, and has determined that it is more likely than not that its net deferred tax assets will not be realized in the United States. Due to uncertainties surrounding the realization of the deferred tax assets, the Company continues to maintain a full valuation allowance against its net deferred tax assets within the United States.

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.

Earnings Per Share [Abstract]
Net Loss Per Share	(10) 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. Prior to the automatic conversion of all of its redeemable convertible preferred stock outstanding into Class B common stock concurrent with the Direct Listing, the Company considered all series of its redeemable convertible preferred stock to be participating securities as holders of such stock had the right to receive nonforfeitable dividends on a ratable basis in the event that a dividend was paid on common stock. Under the two-class method, the net loss attributable to common stockholders was not allocated to the redeemable convertible preferred stock as the preferred stockholders did not have a contractual obligation to share in the Company's losses. 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. 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. The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data): Three Months Ended Nine Months Ended 2022 2021 2022 2021 Net loss attributable to Class A and Class B common stockholders $ ( 22,544 ) $ ( 36,559 ) $ ( 69,332 ) $ ( 53,081 ) Weighted-average shares used in computing net loss per share 112,016 39,301 110,876 32,362 Net loss per share attributable to Class A and Class B $ ( 0.20 ) $ ( 0.93 ) $ ( 0.63 ) $ ( 1.64 ) The following potential common shares were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented (in thousands): As of September 30, 2022 2021 Equity plan stock options outstanding 17,398 23,613 Equity plan stock options early exercised 314 1,054 RSUs outstanding 9,086 1,232 Restricted shares 271 352 Shares issuable pursuant to the ESPP 465 — Total 27,534 26,251

Summary of Business and Signi_2

Summary of Business and Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2022
Accounting Policies [Abstract]
Description of Business	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 companies analyze their customer behavior within 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	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 Note 2 below.
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The condensed 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. 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. The unaudited condensed consolidated balance sheet as of December 31, 2021 included herein was derived from the audited financial statements as of that date, but does not include all disclosures, including certain notes required by U.S. GAAP on an annual reporting basis. In management's opinion, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to state fairly the balance sheet, statements of operations and comprehensive loss, statements of redeemable convertible preferred stock and stockholders' equity (deficit), and statements of cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year or any future period. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”) .
Reclassification	Reclassification Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period condensed consolidated financial statements.
Use of Estimates	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 condensed 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 the Company’s common stock and stock-based awards for periods prior to the direct listing of the Company's Class A common stock on the Nasdaq Capital Market (the “Direct Listing”); • valuation of goodwill and intangible assets; • recognition, measurement, and valuation of deferred tax assets and income tax uncertainties; and • incremental borrowing rate used for operating leases.
Risks and Uncertainties	Risks and Uncertainties While the duration and extent of the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the extent and effectiveness of containment actions, it has already had an adverse effect on the global economy and the lasting effects of the pandemic continue to be unknown. The Company may experience customer losses, including due to bankruptcy or customers ceasing operations, which may result in delays in collections or an inability to collect accounts receivable from these customers. The extent to which COVID-19 may continue to impact the Company’s financial condition, results of operations, or liquidity continues to remain uncertain, and as of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or an adjustment to the carrying value of the Company’s assets or liabilities. These estimates may change, as new events occur and additional information is obtained, which will be recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates, and any such differences may be material to the Company’s financial statements.
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 three and nine months ended September 30, 2022 and 2021. As of the quarter ended September 30, 2022 , one customer represented 17 % of accounts receivable. As of the year ended December 31, 2021, one customer represented 10 % of accounts receivable. Significant Accounting Policies The Company's significant accounting policies are described in the 2021 Form 10-K. There have been no significant changes to these policies that have had a material impact on the Company's condensed consolidated financial statements and related notes for the nine months ended September 30, 2022 other than for the adoption of new accounting guidance related to leases effective January 1, 2022 further described below. 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, if the commencement date was after January 1, 2022, 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 condensed consolidated balance sheets. The current balance of the operating lease liabilities is included within “Accrued expenses” on the Company's condensed 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 condensed consolidated statements of operations and comprehensive loss.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) , which requires companies to recognize lease liabilities and corresponding right-of-use leased assets on the balance sheets and to disclose key information about leasing arrangements. Qualitative and quantitative disclosures will be enhanced to better understand the amount, timing, and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for annual periods beginning after December 15, 2021, with early adoption permitted. Additionally, in 2018 and 2019, the FASB issued the following Topic 842–related ASUs: • 2018-01, Land Easement Practical Expedient for Transition to Topic 842 , which clarifies the applicability of Topic 842 to land easements and provides an optional transition practical expedient for existing land easements; • 2018-10, Codification Improvements to Topic 842, Leases , which makes certain technical corrections to Topic 842; • 2018-11, Leases (Topic 842): Targeted Improvements , which allows companies to adopt Topic 842 without revising comparative period reporting or disclosures and provides an optional practical expedient to lessors to not separate lease and non-lease components of a contract if certain criteria are met; and • 2019-01, Leases (Topic 842): Codification Improvements , which provides guidance for certain lessors on determining the fair value of an underlying asset in a lease and on the cash flow statement presentation of lease payments received; ASU No. 2019-01 also clarifies disclosures required in interim periods after adoption of ASU No. 2016-02 in the year of adoption. The Company adopted the new standard as of January 1, 2022, and recognized a cumulative-effect adjustment to the opening balance of accumulated deficit as of adoption date. The Company elected the optional transition approach to not apply Topic 842 in the comparative periods presented. The Company elected the relief package of practical expedients to not reassess whether existing contracts contain leases, the lease term and classification for existing leases and whether existing initial direct costs meet the new definition. The adoption of Topic 842 resulted in the recognition of total right-of-use of $11.6 million and total lease liabilities of $13.2 million as of the date of adoption. Additionally, the Company has derecognized $1.6 million in deferred rent upon adoption of this standard. The adoption of Topic 842 did not have a material impact to the condensed consolidated statements of operations and comprehensive loss or statements of cash flows. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350) , which eliminates Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on today’s Step 1). This update is effective for annual and interim impairment tests performed in periods beginning after December 15, 2022. The Company early adopted the standard as of January 1, 2022. The adoption of ASC 350 did not have a material impact to the condensed consolidated financial statements.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Financial Instruments - Credit Losses: In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments (Topic 326). This standard revises current U.S. GAAP methodology by requiring measurement and immediate recognition of expected credit losses on in-scope financial instruments, including trade receivables. ASU No. 2016-13 is effective for annual periods beginning after December 15, 2022, with early adoption permitted in fiscal years beginning after December 31, 2018. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements.
