Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	2. Basis of Presentation and Summary of Significant Accounting Policies (a) Principles of Consolidation The accompanying condensed unaudited consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting and as required by Rule 10-01 of Regulation S-X. Accordingly, the condensed unaudited consolidated financial statements may not include all of the information and notes required by GAAP for audited financial statements. The year-end December 31, 2022 consolidated financial statements data included herein was derived from audited financial statements but does not include all disclosures required by GAAP for complete financial statements. In the opinion of the Company’s management, the accompanying condensed unaudited consolidated financial statements contain all adjustments, consisting of items of a normal and recurring nature, necessary to present fairly the Company’s financial position as of March 31, 2023, the results of operations, comprehensive loss and stockholders’ equity for the three-months ended March 31, 2023 and 2022, respectively, and cash flows for the three-months ended March 31, 2023, and 2022, respectively. The results of operations for the three-months ended March 31, 2023 and 2022, respectively, are not necessarily indicative of the results to be expected for the full year. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities, and related disclosures, as of the date of the financial statements, and the amounts of revenues and expenses reported during the period. Actual results could differ from estimates. The accompanying condensed unaudited consolidated financial statements should be read in conjunction with the Company’s audited financial statements and the accompanying notes for the year ended December 31, 2022, which was included in Form 10-K filed with the SEC on February 24, 2023. The accompanying condensed unaudited consolidated financial statements include the accounts of Zeta and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s management considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date of issuance of these financial statements. Certain reclassifications have been made to amounts presented in our condensed unaudited consolidated statement of cash flows for the three months ended March 31, 2022 to conform to the presentation for the three months ended March 31, 2023. (b) Revenue Recognition Revenue arises primarily from the Company’s technology platform via subscription fees, volume-based utilization fees and fees for professional services designed to maximize the customer usage of technology. Revenues are recognized when control of these services is transferred to the customers, in an amount that reflects the consideration we expect to be entitled to an exchange for those services. Sales and other taxes collected by the Company concurrent with revenue-producing activities are excluded from revenues. When the Company enters into contracts with third parties in which the Company is acting as both a vendor and a customer, the Company performs an assessment of the goods or services transferred and presents the revenue and expense based on the fair value of the goods or services provided or received. Contract assets and liabilities Contract assets represent revenue recognized for contracts that have not been invoiced to customers. Total contract assets were $ 5,173 and $ 2,325 as of March 31, 2023 and December 31, 2022, respectively, and are included in the account receivables, net, in the condensed unaudited consolidated balance sheets. Contract liabilities consists of deferred revenues that represent amounts billed to the customers in excess of the revenue recognized. Deferred revenues are subsequently recorded as revenues when earned in accordance with the Company’s revenue recognition policies. During the three months ended March 31, 2023 and 2022, the Company billed and collected $ 3,096 and $ 14,643 in advance, respectively, and recognized $ 1,616 and $ 15,810 , respectively, as revenues. As of March 31, 2023 and December 31, 2022, the deferred revenues were $ 3,708 and $ 2,228 , respectively. Remaining Performance Obligations Remaining performance obligations represents contractual obligations that are not yet fulfilled. Revenues for such contractual obligations will be recognized in future periods. The remaining performance obligations are influenced by several factors, including seasonality, the timing of renewals, average contract terms and foreign currency exchange rates. The remaining performance obligations are subject to future economic risks including counterparty risks, bankruptcies, regulatory changes and other market factors. As of March 31, 2023, the Company's remaining performance obligations for the next twelve months and thereafter were approximately $ 54,600 and $ 75,700 , respectively. Disaggregation of revenues from contract with customers The Company reports disaggregation of revenues based on primary geographical markets and delivery channels / platforms. Revenues by delivery channels / platforms are based on whether the customer requirements necessitate integration with platforms or delivery channels not owned by the Company. When the Company generates revenues entirely through the Company platform, the Company considers it to be Direct Platform Revenues. When the Company generates revenue by leveraging its platform’s integration with third parties, it is considered Integrated Platform Revenues. The following table summarizes disaggregation for the three months ended March 31, 2023 and 2022, respectively. Three months ended March 31, 2023 2022 Direct platform revenues 71 % 81 % Integrated platform revenues 29 % 19 % Refer to the Company’s accounting policy on “Segments” below for more information about disaggregation based on primary geographical markets. (c) Stock-based compensation and other stock-based payments: The measurement of stock-based compensation for all stock-based payment awards, including restricted stock, performance stock units (“PSUs”), shares purchased under its employee stock purchase plan and stock options granted to the employees, consultants or advisors and non-employee directors, is based on the estimated fair value of the awards on the date of grant or date of modification of such grants. The Company accounts for the modification to already issued awards as per guidance in ASC 718-20-35-3 (Refer to "Note 9. Stock-Based Compensation"). The Company accounts for all stock options and restricted shares granted prior to the IPO using a fair value-based method. The fair value of each stock option granted to employees is estimated on the date of the grant using the Black-Scholes-Merton option pricing model, and the related stock-based compensation is recognized over the expected life of the option. The fair value of the restricted shares granted prior to the IPO was determined using the Monte-Carlo simulation method and for the restricted shares granted post-IPO is based on the Company’s closing stock price as of the day prior to the date of the grants. The Company accounts for the forfeitures, as they occur. The Company uses the graded vesting attribution method to recognize the stock-based compensation. The Company accounts for its PSU awards based on the fair value determined using the Monte Carlo simulation method and for its ESPP plan using the Black-Scholes-Merton model, by a third-party valuation firm engaged by the Company. The Company recognizes the stock-based compensation related to these plans on a straight-line basis over the vesting terms associated with these plans. (d) Segments The Company operates as one operating segment. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM is the Chief Executive Officer. Since it operates as one operating segment, all required financial segment information can be found in the condensed unaudited consolidated financial statements. Revenues and long-lived assets by geographic region are based on the physical location of the customers being served or the assets and are as follows: Revenues by geographical region consisted of the following; Three months ended March 31, 2023 2022 US $ 150,406 $ 119,988 International 7,196 6,280 Total revenues $ 157,602 $ 126,268 Total long-lived assets (including right-to-use asset) by geographical region consisted of the following; As of March 31, 2023 December 31, 2022 US $ 46,209 $ 47,858 International 2,083 2,224 Total long-lived assets $ 48,292 $ 50,082 (e) Concentration of Credit Risk No customer accounted for more than 10 % of the Company’s total revenues during the three months ended March 31, 2023 and 2022. Financial instruments that potentially subject the Company to concentration risk consist primarily of accounts receivable from customers. As of March 31, 2023 and December 31, 2022, respectively, there was no customer that represented more than 10 % of accounts receivables balance as of each of those dates. The Company continuously monitors whether there is an expected credit loss arising from customers and accordingly make provisions as warranted. As of the three months ended March 31, 2023, no provision was warranted or recorded. (f) Operating leases: On January 1, 2022, the Company adopted ASC 842, Leases, and recognized right to use assets and operating lease liabilities in its consolidated balance sheets. The Company held an emerging growth company status for 2022, therefore it elected the option to present the impact of adoption within the annual financial statements for the year ended December 31, 2022 and interim statements thereafter. The Company determines if an arrangement is, or contains, a lease at inception, and whether lease and non-lease components are combined or not. A contract is or contains a lease when, (1) the contract contains an identified asset and (2) the customer obtains substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the contract in exchange for consideration. Right-to-use assets and lease liabilities are initially recorded based on the present value of lease payments over the lease term, which includes the minimum unconditional term of the lease, and may include options to extend or terminate the lease when it is reasonably certain at the commencement date that such options will be exercised. Operating leases with a duration of one year or less are excluded from right-of-use assets and lease liabilities and related expense is recorded as incurred. As the rate implicit for each of the Company's leases is not readily determinable, the Company uses its incremental borrowing rate at commencement date in determining the present value of lease payments. Right-of-use assets also include any initial direct costs and any lease payments made prior to the lease commencement date and are reduced by any lease incentives received. Lease expense is recognized on a straight-line basis over the term of the lease. Lease expense is a combination of interest on lease liability and amortization of right-of-use assets. Operating lease expenses are included in general and administrative expenses in the condensed unaudited consolidated statements of operations and comprehensive loss. Refer to "Note 10 - Leases" for additional information. New accounting pronouncements In October 2021, the FASB released ASU No. 2021-08, Business Combinations (Topic 805)- Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this update require that an entity (acquirer) recognize, and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and require application of the new accounting guidance at the beginning of the earliest comparative period presented in the year of adoption, however early adoption is permitted. The guidance is applicable and as such adopted by the Company beginning from January 1, 2023 . However, the adoption of ASU 2021-08 did no t have any material impact on the Company's condensed unaudited consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which was subsequently amended in November 2018 through ASU No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses.” ASU No. 2016-13 requires entities to estimate lifetime expected credit losses for trade and other receivables, net investments in leases, financing receivables, debt securities and other instruments, which will result in earlier recognition of credit losses. Further, the new credit loss model affects how entities in all industries estimate their allowance for losses for receivables that are current with respect to their payment terms. ASU No. 2018-19 further clarifies that receivables arising from operating leases are not within the scope of Topic 326. Instead, impairment from receivables of operating leases should be accounted for in accordance with Topic 842, Leases. As per the latest ASU 2020-02, FASB deferred the timelines for certain small public and private entities, thus the Company adopted the new guidance for the annual reporting period beginning January 1, 2023 and interim periods within that reporting period. The standard applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The adoption of new ASU did no t have any material impact on the Company's condensed unaudited consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	5. Acquisitions The Company uses the purchase method of accounting in accordance with ASC 805, Business Combinations. This standard requires that the total cost of an acquisition be allocated to the tangible and intangible assets acquired and liabilities assumed based on the fair value of the tangible and intangible assets acquired and liabilities assumed at the acquisition date. The Company’s estimates and assumptions used in assessing fair value are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially recorded in connection with a business combination as of the acquisition date. Acquisition-related expenses are expensed when incurred. The Company may also agree to pay a portion of the purchase price for certain acquisitions in the form of contingent consideration. The unpaid amounts of these liabilities are included in the acquisition-related liabilities on the condensed unaudited consolidated balance sheets as of March 31, 2023 and December 31, 2022.

The total consideration of WhatCounts acquisition is $ 15,990 , including $ 1,011 as estimated earn-outs based on the achievement of certain operating targets of the acquired businesses, and $ 128 as working capital adjustment. The Company has recorded this transaction based on the preliminary purchase price allocation. Accordingly, the Company has recognized $ 560 as customer relationships intangibles, $ 6,420 as completed technologies, $ 7,944 as goodwill and $ 1,066 as other net assets associated with this acquisition. The Company amortizes the intangible assets over the weighted average life of 3.2 years. Prior to the acquisition, WhatCounts' technology asset was being used as an Email Service Provider (“ESP”) serving large enterprises, the middle market, and Small and Medium Businesses (“SMBs”). Therefore, the Company paid a premium to acquire these assets, which is represented as Goodwill in the above purchase price allocation. The Company incurred $ 203 as acquisition-related expenses related to this acquisition. Goodwill acquired by the Company in its WhatCounts acquisition is deductible for tax purposes. (b) ArcaMax Publishing, Inc. On March 11, 2022 , the Company entered into a stock purchase agreement with the seller of ArcaMax Publishing, Inc., (“ArcaMax”) to purchase all of its issued and outstanding shares of common stock. The stock purchase agreement was effective March 1, 2022. The fair value of the aggregate purchase consideration for the ArcaMax acquisition was $ 26,925 . The Company paid cash consideration of $ 9,386 (including a working capital adjustment of $ 386 ), issued 926,785 shares of Class A common stock with a fair value of $ 10,000 , and agreed to pay certain earn-outs valued at $ 6,577 based on the operating performance of the acquired business after the closing date in cash and in shares of the Company, $ 962 in cash holdback. During the year ended December 31, 2022, the Company finalized the purchase price allocation for its ArcaMax acquisition.

Prior to the acquisition, ArcaMax was a leader in the development and distribution of more than 400 interest-based newsletters to consumers in the United States, distributing news and syndicating features to a growing opted-in subscriber audience of four million readers. Therefore, the Company paid a premium to acquire ArcaMax assets, which is represented as Goodwill in the above purchase price allocation.

Stock-Based Compensation

Stock-Based Compensation	3 Months Ended
Stock-Based Compensation	Mar. 31, 2023
Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	9. Stock-Based Compensation Stock-based compensation plan In 2008, the Company adopted its 2008 Stock Option/Stock Issuance Plan and, in 2017, the Company adopted the Zeta Global Holdings Corp. 2017 Incentive Plan (collectively, the “Plans”). The Plans permitted the issuance of stock options, restricted stock and restricted stock units to employees, directors and officers, consultants or advisors and non-employee directors of the Company. Options granted under the Plans expire no later than ten years from the grant date. Prior to the IPO, the restricted stock and restricted stock units granted under the Plans generally did not vest until a change in control. Upon a change in control, restricted stock and restricted stock units vest as to 25 % of the shares with the balance of the shares vesting in equal quarterly installments following the change in control over the remainder of a five-year term from the original date of grant. The restricted stock and restricted stock units fully vest upon a change in control to the extent five years has passed from the original date of grant of the restricted stock or restricted stock units. Since the vesting of these awards was contingent upon the change of control event, which was not considered probable until it occurs, the Company did not record any stock-based compensation for such awards prior to the IPO, a change in control event. The stock-based compensation has been recognized following the vesting of restricted stock, restricted stock units and options as described below. In connection with the IPO, the Company adopted the Zeta Global Holdings Corp. 2021 Incentive Award Plan (the “2021 Plan”), which was effective as of the day prior to the first public trading date of our Class A common stock. All restricted stock, restricted stock units and options granted since the IPO have been granted under the 2021 Plan. Under the 2021 Plan, with certain exceptions as permitted by the 2021 Plan, 25 % of the shares shall vest upon the first anniversary of the grant date and balance shall vest in equal quarterly installments over the remainder of a four year term. During the three months ended March 31, 2023 and 2022, the Company recognized stock-based compensation expense of $ 64,462 and $ 73,736 , respectively. Restricted Stock and Restricted Stock Units As noted above, the Company’s restricted stock and restricted stock units granted prior to the IPO did not vest until a change of control. On March 24, 2021, the Company’s board of directors approved a modification in the vesting terms of its restricted stock and restricted stock unit awards. This modification was accounted for under the guidance in ASC 718-20-35-3. Given the vesting of the modified awards contained a performance condition associated with the IPO, the Company had determined that the modification was considered improbable-to-improbable under ASC 718-20-55-118 through 119. The Company recognized compensation expense over the modified vesting terms, based on the fair value as of the date of modification. During the three months ended March 31, 2023, the Company's board of directors approved the modification of the vesting schedule of certain awards granted prior to the IPO, such that the modification accelerated the vesting of those grants. These modifications were accounted for in accordance with ASC 718-20-35-3 and did not have any material impact on the stock-based compensation during the three months ended March 31, 2023. Following is the activity of restricted stock and restricted stock units granted by the Company: Shares Weighted Average Non-vested as of January 1, 2023 60,107,275 $ 10.72 Granted (1) 864,177 9.25 Vested ( 5,534,101 ) 10.56 Forfeited (2) ( 227,421 ) 10.06 Non-vested as of March 31, 2023 (3) 55,209,930 $ 10.72 (1) During the three months ended March 31, 2023, the Company granted 814,177 restricted stock and 50,000 restricted stock units to its employees, advisors and non-employee directors.

Performance Stock Unit (“PSU”) Award Under the 2021 Plan, the Compensation Committee of the Board of Directors approved the grant of PSUs to certain employees during the year ended on December 31, 2022 and 2021. Each PSU represents the right to receive shares of Class A common stock as set forth in the PSU grant agreement or, at the option of the Company, an equivalent amount of cash. Participants have no right to the distribution of any shares or payment of any cash until the time (if ever) the PSUs are earned and have vested. Each PSU provides for the right to receive a dividend equivalent to the value of any ordinary cash dividends paid on substantially all the outstanding shares of Class A common stock if the PSUs are earned and vested. Upon achievement of certain price conditions, the PSUs could result in the issuance of up to 500 % of the PSUs granted in Class A common stock. Such number of shares of Class A common stock shall be earned as a percentage of the PSUs granted, based on the 20-day volume-weighted average closing price per share (“VWAP”) for each quarter. The number of PSUs earned for such quarter shall be reduced by the number of PSUs, if any, earned in any prior quarter. Earned PSUs vest in three equal annual installments, with the first installment vesting on the date the Company determines the number of PSUs that are eligible to vest for such quarter, and the second and third installments vesting on the first and second anniversaries of such determination date, subject to accelerated vesting in connection with certain qualifying terminations of employment or a change in control. As of March 31, 2023, the Company had 3,479,500 outstanding PSUs with the weighted average grant date fair value of $ 12.38 . The Company did no t issue any PSUs during the three months ended March 31, 2023. 2021 Employee Stock Purchase Plan (“ESPP”) On July 28, 2021, the Compensation Committee of the Board of Directors approved the Company’s first offering period under the ESPP, which commenced on August 1, 2021 and ended November 30, 2021. Following the end of the first offering period, the ESPP shall have consecutive offering periods of approximately six months in length commencing each year on December 1 and June 1 and ending on each May 31 and November 30, as applicable. The fair value of the offering that commenced on December 1, 2022 was estimated at $ 3.69 per share, and expected to result in an issuance of approximately 212,998 shares of Class A common stock under this offering that will end on May 31, 2023. Unrecognized compensation expense The Company has $ 303,809 of unrecognized compensation expense related to its 55,209,930 unvested restricted stock and restricted stock units, 3,479,500 performance stock units, 533,110 unvested options and approximately 212,998 shares of Class A common stock to be issued under the ESPP. This unrecognized stock-based compensation will be recognized over a weighted average period of 1.06 years.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	12. Fair Value Disclosures Fair value is the price that would be received from the sale of an asset or paid to transfer a liability assuming an orderly transaction in the most advantageous market at the measurement date. U.S. GAAP establishes a hierarchical disclosure framework which prioritizes and ranks the level of observability of inputs used in measuring fair value. These tiers include Level 1, Level 2 and Level 3. Level 1 is defined as observable inputs such as quoted prices in active markets for identical assets; Level 2 is defined as observable inputs other than Level 1 prices such as quoted prices for similar assets; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3 is defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The following table represents the fair value of the financial instruments measured at fair value on a recurring basis: As of March 31, 2023 Level 1 Level 2 Level 3 Total Assets Cash and cash equivalents* $ 83,884 $ — $ — $ 83,884 Total assets measured at fair value $ 83,884 $ — $ — $ 83,884 Liabilities Acquisition-related liabilities $ — $ — $ 34,486 $ 34,486 Total liabilities measured at fair value $ — $ — $ 34,486 $ 34,486 As of December 31, 2022 Level 1 Level 2 Level 3 Total Assets Cash and cash equivalents* $ 107,354 $ — $ — $ 107,354 Total assets measured at fair value $ 107,354 $ — $ — $ 107,354 Liabilities Acquisition-related liabilities $ — $ — $ 32,675 $ 32,675 Total liabilities measured at fair value $ — $ — $ 32,675 $ 32,675 * Includes cash invested by the Company in certain money market accounts with a financial institution. The following table reconciles the changes in the fair value of the liabilities categorized within Level 3 of the fair value hierarchy for the three months ended March 31, 2023: Acquisition Balance as of January 1, 2023 $ 32,675 Additions, net of payments 159 Change in fair value 1,652 Balance as of March 31, 2023 $ 34,486 In connection with certain business combinations, the Company may owe additional purchase consideration (contingent consideration included in the acquisition-related liabilities) based on the financial performance of the acquired entities after their acquisition. The fair value of the contingent consideration was determined using an unobservable input such as projected revenues, collections of accounts receivables, etc. Changes in any of the assumptions related to the unobservable inputs identified above may change the fair value of the contingent consideration.

Income Taxes	14. Income Taxes The Company’s income tax provision consists of federal, foreign, and state taxes necessary to align the Company’s year-to-date tax provision with the annual effective rate that it expects to achieve for the full year. At each interim period, the Company updates its estimate of the annual effective tax rate and records cumulative adjustments as necessary. For the three months ended March 31, 2023, the Company recorded an income tax provision of $ 198 . The effective tax rate for the three months ended March 31, 2023 was negative 0.3 % on a pre-tax loss of $ 56,757 . For the three months ended March 31, 2022, the Company recorded an income tax benefit of $ 2,599 . The effective tax rate for the three months ended March 31, 2022 was 3.5 % on a pre-tax loss of $ 74,636 . The effective tax rate differs from the U.S. statutory rate primarily related to limited tax benefit recorded for U.S. operating losses as the Company maintains a full valuation allowance against its U.S. deferred tax assets.

Earnings Per Share [Abstract]
Net Loss Per Share Attributable to Common Stockholders	15. Net Loss Per Share Attributable to Common Stockholders Basic net loss per share is computed using the two-class method, by dividing the net loss by the weighted-average number of shares of common stock of the Company outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock of the Company, outstanding stock options, warrants, to the extent dilutive. However, the unvested restricted stock, restricted stock units and performance stock units as of March 31, 2023 and 2022 of 58,689,430 and 72,143,160 respectively, are not considered as participating securities and are anti-dilutive and as such are excluded from the weighted average number of shares used for calculating basic and diluted net loss per share. Basic and diluted net loss per share was the same for each period presented as the inclusion of all potential shares of common stock of the Company outstanding would have been anti-dilutive. The following table sets forth the calculation of basic and diluted net loss per share attributable to common stockholders during the periods presented: Three months ended March 31, 2023 2022 Numerator: Net loss $( 56,955 ) $( 72,037 ) Denominator: Class A common stock 134,420,357 116,232,110 Class B common stock 15,625,483 17,852,593 Denominator for Basic and Dilutive loss per share – weighted-average common stock 150,045,840 134,084,703 Basic loss per share $( 0.38 ) $( 0.54 ) Dilutive loss per share $( 0.38 ) $( 0.54 ) Since the Company was in a net loss position for all periods presented, the inclusion of all potential common equivalent shares outstanding would have been anti-dilutive. Therefore net loss per share attributable to common stockholders was the same on a basic and diluted basis. Anti-dilutive weighted-average common equivalent shares were as follows: Three months ended March 31, 2023 2022 Options 1,109,592 880,846 Restricted stock and restricted stock units 58,773,013 67,499,127 Performance stock units 3,186,642 2,291,800

Accounting Policies [Abstract]
Principles of Consolidation	(a) Principles of Consolidation The accompanying condensed unaudited consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting and as required by Rule 10-01 of Regulation S-X. Accordingly, the condensed unaudited consolidated financial statements may not include all of the information and notes required by GAAP for audited financial statements. The year-end December 31, 2022 consolidated financial statements data included herein was derived from audited financial statements but does not include all disclosures required by GAAP for complete financial statements. In the opinion of the Company’s management, the accompanying condensed unaudited consolidated financial statements contain all adjustments, consisting of items of a normal and recurring nature, necessary to present fairly the Company’s financial position as of March 31, 2023, the results of operations, comprehensive loss and stockholders’ equity for the three-months ended March 31, 2023 and 2022, respectively, and cash flows for the three-months ended March 31, 2023, and 2022, respectively. The results of operations for the three-months ended March 31, 2023 and 2022, respectively, are not necessarily indicative of the results to be expected for the full year. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities, and related disclosures, as of the date of the financial statements, and the amounts of revenues and expenses reported during the period. Actual results could differ from estimates. The accompanying condensed unaudited consolidated financial statements should be read in conjunction with the Company’s audited financial statements and the accompanying notes for the year ended December 31, 2022, which was included in Form 10-K filed with the SEC on February 24, 2023. The accompanying condensed unaudited consolidated financial statements include the accounts of Zeta and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s management considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date of issuance of these financial statements. Certain reclassifications have been made to amounts presented in our condensed unaudited consolidated statement of cash flows for the three months ended March 31, 2022 to conform to the presentation for the three months ended March 31, 2023.
Revenue Recognition	(b) Revenue Recognition Revenue arises primarily from the Company’s technology platform via subscription fees, volume-based utilization fees and fees for professional services designed to maximize the customer usage of technology. Revenues are recognized when control of these services is transferred to the customers, in an amount that reflects the consideration we expect to be entitled to an exchange for those services. Sales and other taxes collected by the Company concurrent with revenue-producing activities are excluded from revenues. When the Company enters into contracts with third parties in which the Company is acting as both a vendor and a customer, the Company performs an assessment of the goods or services transferred and presents the revenue and expense based on the fair value of the goods or services provided or received. Contract assets and liabilities Contract assets represent revenue recognized for contracts that have not been invoiced to customers. Total contract assets were $ 5,173 and $ 2,325 as of March 31, 2023 and December 31, 2022, respectively, and are included in the account receivables, net, in the condensed unaudited consolidated balance sheets. Contract liabilities consists of deferred revenues that represent amounts billed to the customers in excess of the revenue recognized. Deferred revenues are subsequently recorded as revenues when earned in accordance with the Company’s revenue recognition policies. During the three months ended March 31, 2023 and 2022, the Company billed and collected $ 3,096 and $ 14,643 in advance, respectively, and recognized $ 1,616 and $ 15,810 , respectively, as revenues. As of March 31, 2023 and December 31, 2022, the deferred revenues were $ 3,708 and $ 2,228 , respectively. Remaining Performance Obligations Remaining performance obligations represents contractual obligations that are not yet fulfilled. Revenues for such contractual obligations will be recognized in future periods. The remaining performance obligations are influenced by several factors, including seasonality, the timing of renewals, average contract terms and foreign currency exchange rates. The remaining performance obligations are subject to future economic risks including counterparty risks, bankruptcies, regulatory changes and other market factors. As of March 31, 2023, the Company's remaining performance obligations for the next twelve months and thereafter were approximately $ 54,600 and $ 75,700 , respectively. Disaggregation of revenues from contract with customers The Company reports disaggregation of revenues based on primary geographical markets and delivery channels / platforms. Revenues by delivery channels / platforms are based on whether the customer requirements necessitate integration with platforms or delivery channels not owned by the Company. When the Company generates revenues entirely through the Company platform, the Company considers it to be Direct Platform Revenues. When the Company generates revenue by leveraging its platform’s integration with third parties, it is considered Integrated Platform Revenues. The following table summarizes disaggregation for the three months ended March 31, 2023 and 2022, respectively. Three months ended March 31, 2023 2022 Direct platform revenues 71 % 81 % Integrated platform revenues 29 % 19 % Refer to the Company’s accounting policy on “Segments” below for more information about disaggregation based on primary geographical markets.
Stock-based compensation and other stock-based payments:	(c) Stock-based compensation and other stock-based payments: The measurement of stock-based compensation for all stock-based payment awards, including restricted stock, performance stock units (“PSUs”), shares purchased under its employee stock purchase plan and stock options granted to the employees, consultants or advisors and non-employee directors, is based on the estimated fair value of the awards on the date of grant or date of modification of such grants. The Company accounts for the modification to already issued awards as per guidance in ASC 718-20-35-3 (Refer to "Note 9. Stock-Based Compensation"). The Company accounts for all stock options and restricted shares granted prior to the IPO using a fair value-based method. The fair value of each stock option granted to employees is estimated on the date of the grant using the Black-Scholes-Merton option pricing model, and the related stock-based compensation is recognized over the expected life of the option. The fair value of the restricted shares granted prior to the IPO was determined using the Monte-Carlo simulation method and for the restricted shares granted post-IPO is based on the Company’s closing stock price as of the day prior to the date of the grants. The Company accounts for the forfeitures, as they occur. The Company uses the graded vesting attribution method to recognize the stock-based compensation. The Company accounts for its PSU awards based on the fair value determined using the Monte Carlo simulation method and for its ESPP plan using the Black-Scholes-Merton model, by a third-party valuation firm engaged by the Company. The Company recognizes the stock-based compensation related to these plans on a straight-line basis over the vesting terms associated with these plans.
Segments	(d) Segments The Company operates as one operating segment. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM is the Chief Executive Officer. Since it operates as one operating segment, all required financial segment information can be found in the condensed unaudited consolidated financial statements. Revenues and long-lived assets by geographic region are based on the physical location of the customers being served or the assets and are as follows: Revenues by geographical region consisted of the following; Three months ended March 31, 2023 2022 US $ 150,406 $ 119,988 International 7,196 6,280 Total revenues $ 157,602 $ 126,268 Total long-lived assets (including right-to-use asset) by geographical region consisted of the following; As of March 31, 2023 December 31, 2022 US $ 46,209 $ 47,858 International 2,083 2,224 Total long-lived assets $ 48,292 $ 50,082
Concentration of Credit Risk	(e) Concentration of Credit Risk No customer accounted for more than 10 % of the Company’s total revenues during the three months ended March 31, 2023 and 2022. Financial instruments that potentially subject the Company to concentration risk consist primarily of accounts receivable from customers. As of March 31, 2023 and December 31, 2022, respectively, there was no customer that represented more than 10 % of accounts receivables balance as of each of those dates. The Company continuously monitors whether there is an expected credit loss arising from customers and accordingly make provisions as warranted. As of the three months ended March 31, 2023, no provision was warranted or recorded.
Operating leases	(f) Operating leases: On January 1, 2022, the Company adopted ASC 842, Leases, and recognized right to use assets and operating lease liabilities in its consolidated balance sheets. The Company held an emerging growth company status for 2022, therefore it elected the option to present the impact of adoption within the annual financial statements for the year ended December 31, 2022 and interim statements thereafter. The Company determines if an arrangement is, or contains, a lease at inception, and whether lease and non-lease components are combined or not. A contract is or contains a lease when, (1) the contract contains an identified asset and (2) the customer obtains substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the contract in exchange for consideration. Right-to-use assets and lease liabilities are initially recorded based on the present value of lease payments over the lease term, which includes the minimum unconditional term of the lease, and may include options to extend or terminate the lease when it is reasonably certain at the commencement date that such options will be exercised. Operating leases with a duration of one year or less are excluded from right-of-use assets and lease liabilities and related expense is recorded as incurred. As the rate implicit for each of the Company's leases is not readily determinable, the Company uses its incremental borrowing rate at commencement date in determining the present value of lease payments. Right-of-use assets also include any initial direct costs and any lease payments made prior to the lease commencement date and are reduced by any lease incentives received. Lease expense is recognized on a straight-line basis over the term of the lease. Lease expense is a combination of interest on lease liability and amortization of right-of-use assets. Operating lease expenses are included in general and administrative expenses in the condensed unaudited consolidated statements of operations and comprehensive loss. Refer to "Note 10 - Leases" for additional information.
New accounting pronouncements	New accounting pronouncements In October 2021, the FASB released ASU No. 2021-08, Business Combinations (Topic 805)- Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this update require that an entity (acquirer) recognize, and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and require application of the new accounting guidance at the beginning of the earliest comparative period presented in the year of adoption, however early adoption is permitted. The guidance is applicable and as such adopted by the Company beginning from January 1, 2023 . However, the adoption of ASU 2021-08 did no t have any material impact on the Company's condensed unaudited consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which was subsequently amended in November 2018 through ASU No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses.” ASU No. 2016-13 requires entities to estimate lifetime expected credit losses for trade and other receivables, net investments in leases, financing receivables, debt securities and other instruments, which will result in earlier recognition of credit losses. Further, the new credit loss model affects how entities in all industries estimate their allowance for losses for receivables that are current with respect to their payment terms. ASU No. 2018-19 further clarifies that receivables arising from operating leases are not within the scope of Topic 326. Instead, impairment from receivables of operating leases should be accounted for in accordance with Topic 842, Leases. As per the latest ASU 2020-02, FASB deferred the timelines for certain small public and private entities, thus the Company adopted the new guidance for the annual reporting period beginning January 1, 2023 and interim periods within that reporting period. The standard applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The adoption of new ASU did no t have any material impact on the Company's condensed unaudited consolidated financial statements.
