Basis Of Presentation And Summary Of Significant Accounting Policies [Abstract] |
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and include the operations of the Company, Viant Technology LLC and its wholly owned subsidiaries. Viant Technology LLC is considered a variable interest entity. The Company is the primary beneficiary and sole managing member of Viant Technology LLC and has decision-making authority that significantly affects the economic performance of the entity. As a result, the Company consolidates Viant Technology LLC. All intercompany balances and transactions have been eliminated in consolidation. Management believes that the accompanying condensed consolidated financial statements reflect the adjustments necessary for the fair statement of its condensed consolidated financial statements included in this Quarterly Report on Form 10-Q. The condensed consolidated balance sheet as of December 31, 2024 was derived from the audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. Certain information and disclosures normally included in the Company's consolidated financial statements prepared in accordance with GAAP have been omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in its Annual Report on Form 10-K for the year ended December 31, 2024. The condensed consolidated statements of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2025, or for any other future annual or interim period. There have been no material changes to the significant accounting policies as described in the Company's Annual Report on Form 10-K for the year ended December 31, 2024.
Use of Estimates | Use of Estimates The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures 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. On an ongoing basis, management evaluates its estimates, primarily those related to revenue recognition, stock-based compensation, income taxes, allowances for doubtful accounts, the useful lives of capitalized software development costs and other property, equipment, and software and assumptions used in the impairment analyses of long-lived assets, investments and goodwill. These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amount of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The impact of widespread macroeconomic and geopolitical uncertainties, including the impact of bank failures, tariffs and international trade conflict, high interest rates, inflationary pressures, labor shortages, shortages of goods and services, supply chain constraints, pandemics, political cycles, changes in laws and interpretations of laws, international conflicts and acts of terrorism on our business continues to evolve. Many of our estimates and assumptions consider these macroeconomic and geopolitical factors in the market, which require increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available on the potential impact on our business of global economic and business events, our estimates may change materially in future periods as a result.
Comprehensive Income (Loss) | Comprehensive Income For the periods presented, net income is equal to comprehensive income. Segment Information The Company has a single reportable operating segment which owns and operates an enterprise technology platform that enables the Company, marketers and their advertising agencies to centralize the planning, buying and measurement of their video, audio and display ads across all channels, including CTV, streaming audio, digital out-of-home, mobile and desktop in the United States. The Company derives its revenues from the services it provides through utilization of its platform. In reaching this conclusion of a single reportable operating segment, management considers the definition of the chief operating decision maker (“CODM”), how the business is defined by the CODM, the nature of the information provided to the CODM and how that information is used to make operating decisions, allocate resources and assess performance. The Company’s CODM is comprised of the chief executive officer and chief operating officer. The CODM uses multiple measures within the consolidated statements of operations, balance sheets, and cash flows and thus utilizes the entirety of those consolidated statements to make key resource decisions and assess performance at the consolidated level. The CODM does not review segment assets at a different asset level and category. The consolidated net income (loss) is the measure of segment net income (loss) that is most consistent with U.S. GAAP.
Cash and Cash Equivalents | Cash and Cash Equivalents For purposes of balance sheet presentation and reporting of cash flows, the Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Cash and cash equivalents are comprised of cash in bank accounts and money market funds for which the carrying value approximates fair value due to their short-term nature. Cash equivalents are valued based on Level 1 inputs which consist of quoted prices in active markets. As of September 30, 2025, cash equivalents included money market funds of $149.8 million.
Accounts Receivable, Net of Allowances | Accounts Receivable, Net of Allowances The following table presents changes in the allowance for doubtful accounts for the nine months ended September 30, 2025:
| (in thousands)
Balance as of December 31, 2024 | $ | 2,065 |
Provision for doubtful accounts | 10 |
Write-offs, net of recoveries | (1,190) |
Balance as of September 30, 2025 | $ | 885 |
Concentration of Risk | Concentration of Risk Financial instruments that potentially subject the Company to concentration of risk consist principally of cash and cash equivalents and accounts receivable. The Company maintains its cash with financial institutions and its cash levels exceed the Federal Deposit Insurance Corporation’s federally insured limits. Market conditions can impact the viability of these institutions. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we will be able to access uninsured funds in a timely manner or at all. Accounts receivable include amounts due from customers with principal operations primarily in the United States.
Non-Marketable Equity Securities | Non-Marketable Equity Securities We hold investments in non-marketable equity securities that represent investments in privately held companies without readily determinable fair values. The Company measures investments without readily determinable fair values at cost, less impairment, adjusted for observable price changes. These investments are included within other assets on our condensed consolidated balance sheets. As of September 30, 2025, the Company had non-marketable equity investments without readily determinable fair value of $3.5 million. The Company did not record any adjustments to the carrying value resulting from observable price changes and did not record any related impairment for the nine months ended September 30, 2025. Additionally, we did not recognize any gains or losses in the value of these investments for the nine months ended September 30, 2025.
JOBS Act Election as an Emerging Growth Company | JOBS Act Election as an Emerging Growth Company On April 5, 2012, the Jumpstart Our Business Startups Act (the “JOBS Act”) was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for qualifying public companies. As an “emerging growth company,” the Company may, under Section 7(a)(2)(B) of the Securities Act of 1933, as amended (the “Securities Act”), delay adoption of new or revised accounting standards applicable to public companies until such standards would otherwise apply to private companies. An “emerging growth company” is one with less than $1.235 billion in annual gross revenues, has issued $1 billion or less of non-convertible debt over a three-year period and is not deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission (“SEC”). The Company will remain an emerging growth company until December 31, 2026, or sooner if it no longer qualifies. The Company has elected to take advantage of the benefits of this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the first to occur of the date that it (i) is no longer an “emerging growth company” or (ii) affirmatively and irrevocably opts out of this extended transition period provided by Securities Act Section 7(a)(2)(B).
Recently Issued and Recent Adopted Accounting Pronouncements | Recently Issued Accounting Pronouncements Disclosure Improvements In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. ASU 2023-06 includes a number of amendments to clarify or improve disclosure and presentation requirements of a variety of topics in order to allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements and to align the requirements in the FASB accounting standard codification with the SEC's regulations. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. This ASU is not expected to have a material impact on the Company's condensed consolidated financial statements. Income Taxes In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 is designed to enhance the transparency and decision usefulness of annual income tax disclosures. The amendments of this update are related to the rate reconciliation and income taxes paid, requiring consistent categories and greater disaggregation of information in the rate reconciliation as well as income taxes paid disaggregated by jurisdiction. The effective date for this ASU is for annual periods beginning after December 15, 2024 on a prospective basis, with a retrospective option, and early adoption permitted. The Company is currently evaluating the impact that adoption of this ASU will have on our financial disclosures. Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosure (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 requires disclosure of additional information about specific expense categories in the notes to financial statements on an annual and interim basis. The effective date for this ASU is for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of these amendments. Internal-Use Software In September 2025, the FASB issued ASU No. 2025-06, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendments in this update clarify and modernize the accounting for costs related to internal-use software, affecting when an entity is required to start capitalizing software costs. The effective date for this ASU is for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact of these amendments. Recently Adopted Accounting Pronouncements Financial Instruments—Credit Losses In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). ASU 2016-13 revises the impairment model to utilize an expected loss methodology in place of the incurred loss methodology, which results in more timely recognition of losses on financial instruments. We adopted this standard at the beginning of the fiscal year ended December 31, 2023. As a result, we revised the impairment model to utilize an expected loss methodology in place of an incurred loss methodology related to our allowance for credit losses. We evaluate our allowance for credit losses based on historical bad debt experience, our assessment of the financial condition of companies with which we do business, current macroeconomic conditions and reasonable and supportable forecasts of future macroeconomic conditions. The adoption did not have a material impact on the Company's condensed consolidated financial statements.
