Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Significant Accounting Policies	Description of Business and Significant Accounting Policies Description of Business ON24, Inc. and its subsidiaries (together, ON24 or the Company) provides a leading, cloud-based platform for digital engagement that enables businesses to convert customer engagement into revenue through interactive webinar experiences, virtual event experiences and multimedia content experiences. The Company’s platform offers a portfolio of interactive, personalized and content-rich digital experience products that creates and captures actionable, real-time data at scale from millions of professionals every month to provide businesses with buying signals and behavioral insights to efficiently convert prospects into customers. The Company was incorporated in the state of Delaware in January 1998 as NewsDirect, Inc. and in December 1998 changed its name to ON24, Inc. The Company is headquartered in San Francisco, California. Initial Public Offering On February 5, 2021, the Company closed its initial public offering (IPO) of 7,599,928 shares of its common stock at a public offering price of $50 per share for net proceeds of approximately $347.8 million, after deducting the underwriting discount of approximately $26.6 million and other offering costs of approximately $5.6 million. The shares of common stock sold in the IPO and the net proceeds from the IPO included the full exercise of the underwriters’ option to purchase additional shares. Upon the closing of the IPO, all of the Company's outstanding shares of Class A-1 and Class A-2 convertible preferred stock and Class B and Class B-1 redeemable convertible preferred stock were automatically converted into an aggregate of 27,227,466 shares of common stock on a one-for-one basis. Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial reporting. Certain information and note disclosures included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2021. In the opinion of management, the condensed consolidated financial statements reflect all adjustments that are normal and recurring in nature and necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the operating results anticipated for the full year. Certain prior period amounts have been reclassified on the condensed consolidated balance sheets and in Note 5 to conform to the current year's presentation. Prior to the adoption of Accounting Standard Update (ASU) No. 2016-02 Leases (Topic 842) on January 1, 2022 (as further discussed below), capital leases and equipment loans were reported together as long-term debt, current and non-current, on the condensed consolidated balance sheets. Upon the adoption of the new lease standard, capital leases are now presented separately as finance leases, current and non-current, on the condensed consolidated balance sheets. The current and non-current portion of equipment loans have been reclassified to accrued and other current liabilities and other long-term liabilities, respectively, on the condensed consolidated balance sheets. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant items subject to such estimates and assumptions include, but are not limited to, the estimated expected benefit period for deferred contract acquisition costs, the determination of standalone selling price for the Company’s performance obligations, the allowance for doubtful accounts and billing reserve, the useful lives of long-lived assets, the assumptions used to measure stock-based compensation, the valuation of deferred income tax assets and uncertain tax positions. Actual results could differ from those estimates. Significant Accounting Policies The Company’s significant accounting policies are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2021. Other than the changes to the accounting policy for leases related to the adoption of ASC 842 on January 1, 2022 discussed below, there has been no material change to the Company’s significant accounting policies during the three months ended March 31, 2022. Leases The Company determines if an arrangement is a lease at inception. Lease liabilities are recognized at the lease commencement date based on the present value of the future lease payments over the lease term. The interest rate used to determine the present value of the future lease payments is the Company's incremental borrowing rate because the interest rate implicit in its leases is not readily determinable. Right-of-use asset (ROU) asset is determined based on the lease liability initially established and reduced for any prepaid lease payments and any lease incentives received. The lease term to calculate the ROU asset and related lease liability may include options to extend or terminate the lease when the Company is reasonably certain that it will exercise the option. Variable lease payments are expensed as incurred and are not included in the ROU assets and lease liabilities Leases with an initial term of 12 months or less are recognized in the condensed consolidated statements of operations on a straight-line basis over the lease term. Lease expense is recognized on a straight-line basis over the lease term. The Company accounts for lease components and non-lease components as a single lease component for its new or modified office facility operating leases entered into on or after January 1, 2022. Recently Adopted Accounting Standards In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, Financial Instruments Topic 326: Credit Losses Measurement of Credit Losses on Financial Instruments (Topic 326), as amended, which requires an entity to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts utilizing a new impairment model known as the current expected credit loss (CECL) model. The new guidance affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities, excluding entities eligible to be smaller reporting companies as defined by the SEC, ASU No. 2016-13, is effective for the annual periods in fiscal years beginning after December 15, 2019, and interim periods therein. For all other entities ASU No. 2016-13, is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal year. The Company has elected to use the extended transition period that allows the Company to delay adoption of new or revised accounting pronouncements until such pronouncements are made applicable to private companies under the Jumpstart Our Business Startups Act of 2012. The Company is currently evaluating the impact of adopting this standard and does not expect the adoption to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), as amended, to supersede existing guidance on accounting for leases in Topic 840, Leases . Topic 842 generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. The Company adopted the new lease standard effective January 1, 2022 on a modified retrospective basis using the effective date transition method, which applied the provisions of the new guidance at the effective date without adjusting the comparative periods presented. On the adoption date, the Company recognized on its condensed consolidated balance sheets $7.2 million of additional right-of-use assets, $9.6 million additional lease liabilities, and derecognized existing deferred rent and lease incentives totaling $2.4 million. The Company’s accounting for finance leases remained substantially unchanged. The Company elected a number of the practical expedients permitted under the transition guidance within the new standard. This included the election to apply the practical expedient package upon transition, which comprised the following: • The Company did not reassess whether expired or existing contracts are or contain a lease; • The Company did not reassess the classification of existing leases; and • The Company did not reassess the accounting treatment for initial direct costs. The Company also elected to apply the hindsight practical expedient which allows the Company to use hindsight in determining the lease term. In addition, the Company elected the practical expedient related to short-term leases, which allows the Company not to recognize a ROU asset and lease liability for leases with an initial expected term of 12 months or less. The Company also elected to account for lease and non-lease components as a single lease component for operating facility leases.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Disaggregation of Revenue The following table depicts the disaggregation of revenue by geographic region based on the shipping address of customers (in thousands): Three Months Ended March 31, 2022 2021 United States $ 36,549 $ 36,954 EMEA 8,147 9,496 Other 3,796 3,649 Total revenue $ 48,492 $ 50,099 The following table summarizes the foreign countries which contributed 10% or more of the total revenue (in thousands) : Three Months Ended March 31, 2022 2021 United Kingdom * 12 % * Represent less than 10% of total revenue No single customer accounted for 10% or more of the total revenue during the three months ended March 31, 2022 and 2021. Additionally, no single customer accounted for 10% or more of accounts receivable as of March 31, 2022 and December 31, 2021. Contract Balances Accounts receivable : The Company records accounts receivable when the Company has a contractual right to consideration. In some arrangements, a right to consideration for the Company’s performance under the customer contract may occur before invoicing to the customer, resulting in an unbilled receivable. As of March 31, 2022 and December 31, 2021, unbilled receivables were included within accounts receivable, net of allowance for doubtful accounts and billing reserves on the condensed consolidated balance sheets and were not material. Contract assets: The Company records a contract asset when the Company has satisfied a performance obligation but does not yet have an unconditional right to consideration. Contract assets are included in prepaid expenses and other current assets in the condensed consolidated balance sheets and were not material as of March 31, 2022 and December 31, 2021. Contract liabilities : The Company defers its revenue when the Company has the right to invoice in advance of performance under a customer contract. The current portion of deferred revenue balances is recognized during the following 12-month period and the remaining portion is recorded as noncurrent, which is included in other long-term liabilities on the condensed consolidated balance sheet. The amount of revenue recognized in the three months ended March 31, 2022 that was included in deferred revenue at the beginning of the period was $40.0 million. Remaining Performance Obligations The terms of the Company’s subscription agreements are primarily annual and, to a lesser extent, multi-year. The Company may bill for the full term in advance or on an annual, quarterly or monthly basis, depending on the terms of the agreement. As of March 31, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was $146.5 million, which consists of both billed consideration in the amount of $92.8 million and unbilled consideration in the amount of $53.7 million that the Company expects to recognize as revenue. As of March 31, 2022, the Company expects to recognize 81% of its remaining performance obligations as revenue over the subsequent 12 months and the remainder thereafter. Costs to Obtain a Contract The Company capitalizes sales commissions and associated payroll taxes paid to internal sales personnel and third-party referral fees that are incremental costs resulting from obtaining a contract with a customer. These costs are recorded as deferred contract acquisition costs on the condensed consolidated balance sheets. The Company determines whether costs should be deferred based on its sales compensation plans and if the commissions are incremental and would not have occurred absent the customer contract. Sales commissions paid upon the initial acquisition of a customer contract are amortized over an estimated period of benefit of five years as the Company specifically anticipates renewals of customer contracts and commissions paid on renewal contracts are not commensurate with commissions paid on new customer contracts. Sales commissions paid upon renewal of customer contracts are amortized over the contractual renewal term. Amortization is recognized on a straight-line basis commensurate with the pattern of revenue recognition. Sales commissions paid related to professional services are amortized over the expected service period. The Company determines the period of benefit for commissions paid for the acquisition of the initial customer contract by taking into consideration the initial estimated customer life and the technological life of its platform and related significant features. Amortization of deferred contract acquisition costs was $4.1 million and $3.7 million for the three months ended March 31, 2022 and 2021, respectively. and is included in sales and marketing expense in the condensed consolidated statements of operations. The Company periodically reviews these deferred contract acquisition costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit. The Company has no impairment losses relating to deferred contract acquisition costs during the periods presented.

The Company reviews the individual securities that have unrealized losses on a regular basis to evaluate whether any security has experienced other-than-temporary decline in fair value below amortized cost. The Company evaluates, among other factors, whether the Company has the intention to sell any of these marketable securities and whether it is more likely than not that the Company will be required to sell any securities before recovery of the amortized cost basis. Since the Company has the ability to hold its investments until maturity, and the decline in fair value was not due to any credit-related factor, no decline was deemed to be other-than-temporary. The Company had no realized gains or losses from marketable securities that were reclassified out of accumulated other comprehensive income for the three months ended March 31, 2022 and 2021.

Debt Disclosure [Abstract]
Credit Facility	Credit Facility In September 2021, the Company amended its revolving line of credit with a financial institution effective August 2021, which increased the Company's borrowing capacity to a maximum of $50.0 million with a letter of credit sublimit of $4.0 million and a credit card sublimit of $1.0 million. The amendment allows the Company to borrow up to $50.0 million if the Company maintains at least $100.0 million on deposit at the institution. If such deposit is less than $100.0 million, the Company may borrow up to the lesser of $50.0 million or an amount determined by the Company's trailing five months of recurring revenue, annualized renewal rate and annualized monthly churn rate, as defined by the agreement. As of March 31, 2022, the Company did not draw down on its line of credit and has a borrowing capacity of $50.0 million. The terms of the agreement permit voluntary prepayment without premium or penalty. The revolving credit facility matures in August 2024 and is secured by substantially all of the Company’s assets. The outstanding principal balance on the revolving line of credit, if any, is due at maturity. The Company is required to pay quarterly in arrears a commitment fee of 0.15% per annum on the undrawn portion available under the revolving line of credit. As of March 31, 2022, the Company had an outstanding standby letter of credit of $1.2 million as a guarantee for a leased space. Interest on the revolving credit facility is payable monthly in arrears at a rate equal to the lender’s prime referenced rate as defined in the agreement. Prior to this amendment, interest on the revolving line of credit was the prime rate, as published by the Wall Street Journal (Prime Rate), plus 0.75% effective July 31, 2020, and Prime Rate plus 0.50% prior to July 31, 2020. The referenced prime rate was 3.50% as of March 31, 2022 and the Prime Rate was 3.25% as of March 31, 2021, respectively. The revolving credit facility is subject to certain restrictions and financial covenants, including the requirement of maintaining a minimum debt to EBITDA ratio when the Company’s current portion of the total borrowing exceeds $5.0 million and the Company fails to maintain $100.0 million on deposits. In addition, the revolving line of credit agreement restricts the Company from paying dividends without prior approval from the financing institution. The Company was not subject to the financial covenants as of March 31, 2022.

Commitments and Contingencies Disclosure [Abstract]
Commitment and Contingencies	Commitment and Contingencies Purchase Obligations The Company has non-cancelable purchase commitments of $5.1 million as of March 31, 2022, primarily related to software license fees and co-location facilities and services, of which $2.7 million is expected to be paid in remainder of 2022, $2.3 million in 2023 and $0.1 million in 2024. Contingencies The Company has agreed to indemnify its directors and executive officers for costs associated with any fees, expenses, judgments, fines, and settlement amounts incurred by any of these persons in any action or proceeding to which any of those persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by the Company, arising out of that person’s services as the Company’s director or officer or that person’s services provided to any other company or enterprise at the Company’s request. The Company maintains director and officer insurance coverage that may enable the Company to recover a portion of any future amounts paid. FASB ASC 450-20, Contingencies , sets forth the rules for accounting for uncertain tax positions for taxes not based on income. When a loss contingency exists, the likelihood of the incurrence of the liability can range from probable to remote. The Company believes it is reasonably possible that a loss will result from the sales and use tax assessments in the range of zero to $0.4 million. The Company has not recorded an accrual as of March 31, 2022 and 2021. Legal Proceedings The Company, its Chief Executive Officer, its Chief Financial Officer, the members of its Board of Directors and the underwriters that participated in the Company’s IPO are named as defendants in a consolidated putative class action, captioned In re ON24, Inc. Securities Litigation, 4:21-cv-08578-YGR (filed November 3, 2021), that is currently pending in the United States District Court for the Northern District of California. The consolidated complaint purports to assert claims under Sections 11 and 15 of the Securities Act of 1933 on behalf of all persons and entities that purchased, or otherwise acquired, the Company’s common stock issued in connection with the Company’s IPO. The complaints allege that the Company’s registration statement and prospectus contained untrue statements of material fact and/or omitted material facts about ON24’s growth and customer base. Plaintiffs seek, among other things, an award of damages and attorneys’ fees and costs. The Company believes the allegations in the lawsuits are without merit. The Company is unable to reasonably estimate a possible loss or range of possible loss, if any, arising from this matter at this early stage. Accordingly, no accrued litigation expense has been recorded in the accompanying condensed consolidated financial statements. In the ordinary course of business, the Company may be subject from time to time to various proceedings, lawsuits, disputes or claims. Although the Company cannot predict with assurance the outcome of any litigation, the Company does not believe there are currently any actions, other than those described in the prior paragraph, that if resolved unfavorably, would have a material impact on its financial condition, results of operations or cash flows.

Provision for income taxes for the three months ended March 31, 2022 decreased $0.2 million, compared to the three months ended March 31, 2021. The change in provision for income taxes was primarily driven by the tax benefits associated with stock-based compensation benefit in a foreign jurisdiction.

As of March 31, 2022, the Company recorded a valuation allowance against its U.S. deferred tax assets based on available evidence. However, if there are favorable changes to actual operating results or to projections of future income, the Company may determine that it is more likely than not that such deferred tax assets may be realizable. Utilization of net operating loss carryforwards, tax credits and other attributes may be subject to future annual limitations due to the ownership change limitations provided by Section 382 of the Internal Revenue Code and similar state provisions.

All intercompany transactions and balances have been eliminated in consolidation. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the operating results anticipated for the full year.
Prior Period Reclassification Adjustment	Certain prior period amounts have been reclassified on the condensed consolidated balance sheets and in Note 5 to conform to the current year's presentation. Prior to the adoption of Accounting Standard Update (ASU) No. 2016-02 Leases (Topic 842) on January 1, 2022 (as further discussed below), capital leases and equipment loans were reported together as long-term debt, current and non-current, on the condensed consolidated balance sheets. Upon the adoption of the new lease standard, capital leases are now presented separately as finance leases, current and non-current, on the condensed consolidated balance sheets. The current and non-current portion of equipment loans have been reclassified to accrued and other current liabilities and other long-term liabilities, respectively, on the condensed consolidated balance sheets.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant items subject to such estimates and assumptions include, but are not limited to, the estimated expected benefit period for deferred contract acquisition costs, the determination of standalone selling price for the Company’s performance obligations, the allowance for doubtful accounts and billing reserve, the useful lives of long-lived assets, the assumptions used to
Leases	Leases The Company determines if an arrangement is a lease at inception. Lease liabilities are recognized at the lease commencement date based on the present value of the future lease payments over the lease term. The interest rate used to determine the present value of the future lease payments is the Company's incremental borrowing rate because the interest rate implicit in its leases is not readily determinable. Right-of-use asset (ROU) asset is determined based on the lease liability initially established and reduced for any prepaid lease payments and any lease incentives received. The lease term to calculate the ROU asset and related lease liability may include options to extend or terminate the lease when the Company is reasonably certain that it will exercise the option. Variable lease payments are expensed as incurred and are not included in the ROU assets and lease liabilities Leases with an initial term of 12 months or less are recognized in the condensed consolidated statements of operations on a straight-line basis over the lease term. Lease expense is recognized on a straight-line basis over the lease term. The Company accounts for lease components and non-lease components as a single lease component for its new or modified office facility operating leases entered into on or after January 1, 2022.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, Financial Instruments Topic 326: Credit Losses Measurement of Credit Losses on Financial Instruments (Topic 326), as amended, which requires an entity to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts utilizing a new impairment model known as the current expected credit loss (CECL) model. The new guidance affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities, excluding entities eligible to be smaller reporting companies as defined by the SEC, ASU No. 2016-13, is effective for the annual periods in fiscal years beginning after December 15, 2019, and interim periods therein. For all other entities ASU No. 2016-13, is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal year. The Company has elected to use the extended transition period that allows the Company to delay adoption of new or revised accounting pronouncements until such pronouncements are made applicable to private companies under the Jumpstart Our Business Startups Act of 2012. The Company is currently evaluating the impact of adopting this standard and does not expect the adoption to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), as amended, to supersede existing guidance on accounting for leases in Topic 840, Leases . Topic 842 generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. The Company adopted the new lease standard effective January 1, 2022 on a modified retrospective basis using the effective date transition method, which applied the provisions of the new guidance at the effective date without adjusting the comparative periods presented. On the adoption date, the Company recognized on its condensed consolidated balance sheets $7.2 million of additional right-of-use assets, $9.6 million additional lease liabilities, and derecognized existing deferred rent and lease incentives totaling $2.4 million. The Company’s accounting for finance leases remained substantially unchanged. The Company elected a number of the practical expedients permitted under the transition guidance within the new standard. This included the election to apply the practical expedient package upon transition, which comprised the following: • The Company did not reassess whether expired or existing contracts are or contain a lease; • The Company did not reassess the classification of existing leases; and • The Company did not reassess the accounting treatment for initial direct costs. The Company also elected to apply the hindsight practical expedient which allows the Company to use hindsight in determining the lease term. In addition, the Company elected the practical expedient related to short-term leases, which allows the Company not to recognize a ROU asset and lease liability for leases with an initial expected term of 12 months or less. The Company also elected to account for lease and non-lease components as a single lease component for operating facility leases.
Revenue Recognition	Accounts receivable: The Company records accounts receivable when the Company has a contractual right to consideration. In some arrangements, a right to consideration for the Company’s performance under the customer contract may occur before invoicing to the customer, resulting in an unbilled receivable.Contract assets: The Company records a contract asset when the Company has satisfied a performance obligation but does not yet have an unconditional right to consideration.Contract liabilities: The Company defers its revenue when the Company has the right to invoice in advance of performance under a customer contract. The current portion of deferred revenue balances is recognized during the following 12-month period and the remaining portion is recorded as noncurrent, which is included in other long-term liabilities on the condensed consolidated balance sheet.
