Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	NOTE 2: SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates on an ongoing basis its assumptions, including those related to contingencies, income tax uncertainties, incremental borrowing rate for operating leases, fair value of financial assets and liabilities, including fair value of derivatives, fair value and useful life of intangible assets, as well as in estimates used in applying the revenue recognition policy. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates. Financial Statements in U.S. Dollars The currency of the primary economic environment in which the operations of Kaltura Inc. and its subsidiaries are conducted is the U.S. dollar; thus, the dollar is the functional currency of Kaltura Inc. and its subsidiaries. Accordingly, monetary accounts maintained in currencies other than the U.S. dollar are remeasured into U.S. dollars in accordance with Statement of the Accounting Standard Codification ("ASC") 830 "Foreign Currency Matters" ("ASC 830"). All transaction gains and losses of the remeasured monetary balance sheet items are reflected in the statements of operations as financial income or expenses, as appropriate. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany transactions and balances have been eliminated upon consolidation. Cash and Cash Equivalents Cash equivalents are short term, highly liquid investments that are readily convertible to cash with original maturities of three months or less, at the date acquired. Restricted Cash Restricted cash is primarily invested in deposits held to maturity, stated at cost, which also approximates their fair value, and are used as security for the Company's liabilities. These deposits are used mainly as security for rent payments, and the Company's credit cards. Restricted cash is presented in the balance sheet as part of other assets, noncurrent. Marketable Securities The Company accounts for investments in marketable securities in accordance with ASC No. 320, “Investments - Debt Securities”. Management determines the appropriate classification of its investments at the time of purchase and reevaluates such determinations at each balance sheet date. The Company classifies all of its debt securities as available-for-sale. Available-for-sale debt securities are carried at fair value, with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive income (loss) in shareholders’ equity. Realized gains and losses on sale of investments are included in financial expenses (income), net and are derived using the specific identification method for determining the cost of securities sold. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization together with interest on securities is included in financial income, net. The Company periodically evaluates its available-for-sale debt securities for impairment. If the amortized cost of an individual security exceeds its fair value, the Company considers its intent to sell the security or whether it is more likely than not that it will be required to sell the security before recovery of its amortized basis. If either of these criteria are met, the Company writes down the security to its fair value and records the impairment charge in financial expenses (income), net in the Consolidated Statements of Operations. If neither of these criteria are met, the Company determines whether credit loss exists. Credit loss is estimated by considering changes to the rating of the security by a rating agency, any adverse conditions specifically related to the security, as well as other factors. Trade Receivables Derivatives and Hedging Derivatives are recognized at fair value as either assets or liabilities in the consolidated balance sheets in accordance with ASC Topic 815, “Derivatives and Hedging.” The gain or loss of derivatives that are designated and qualify as hedging instruments in a cash flow hedge, is recorded under accumulated other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Derivatives are classified within Level 2 of the fair value hierarchy as the valuation inputs are based on quoted prices and market observable data of similar instruments. Property and Equipment, net Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets: Years Computers and peripheral equipment 3 Office furniture and equipment 7-15 Leasehold improvements Over the shorter of the related lease period or the life of the asset Impairment of Long-Lived Assets The long-lived assets of the Company are reviewed for impairment in accordance with ASC 360, “Property, Plant and Equipment” (“ASC 360”), whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. There were no impairment charges to long-lived assets during the periods presented. Intangible Assets, net Intangible ass ets con sist primarily of customer relationships, technology and trade name. The intangible assets are amortized over their estimated useful lives in proportion to the economic benefits realized. Intangible assets consist primarily of customer relationships, technology, and trade name. Amortization for the intangible assets was recognized over the following periods: Years Customer relationships 7-9 Technology 5-8 Tradename 10 Goodwill Goodwill re presents the excess of the purchase price over the fair value of net assets acquired in business combinations using the acquisition method of accounting, which requires that the assets acquired and liabilities assumed be recorded at the date of acquisition at their respective fair values. Goodwill is subject to an impairment test at the reporting unit level at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. The Company identified two reporting units - EE&T and M&T. Goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value. An impairment loss is recognized in an amount equal to the excess. There were no impairment charges to goodwill during the periods presented. Leases The Company determines if an arrangement is a lease at inception. The Company currently does not have any finance leases. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The Company combines its lease payments and fixed payments for non-lease components and account for them together as a single lease component. Operating lease ROU assets also include any prepaid lease payments and lease incentives. Certain lease agreements include rental payments adjusted periodically for the consumer price index (“CPI”). The ROU and lease liability were calculated using the initial CPI and will not be subsequently adjusted, unless the liability is reassessed for other reasons. Payments for variable lease costs are expensed as incurred and not included in the operating lease ROU assets and liabilities. For short-term leases with a term of 12 months or less, operating lease ROU assets and liabilities are not recognized and the Company records lease payments in the Consolidated Statements of Operations on a straight-line basis 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 the Company’s leases is not readily determinable. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Many of the Company’s lease agreements provide one or more options to renew. When determining lease terms, the Company uses the non-cancellable period of the leases and do not assume renewals unless it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term. The majority of Kaltura Israel's agreements with its employees in Israel are in accordance with section 14 of the Israeli Severance Pay Law. Upon contribution of the full amount of the employee's monthly salary and release of the policy to the employee, no additional legal obligation exists between the parties and no additional payments are made by the Company to the employee; therefore, related assets and liabilities are not presented in the balance sheet. For Kaltura Israel employees who are not subject to section 14, the Company calculated the liability for severance pay pursuant to the Severance Pay Law based on the most recent salary of these employees multiplied by the number of years of employment as of the balance sheet date. Kaltura Israel's liability for these employees is fully provided for via monthly deposits with severance pay funds, insurance policies and an accrual. The value of these deposits is recorded as an asset on the Company's balance sheet in other assets, noncurrent. Severance expenses recorded in Kaltura Israel for the years ended December 31, 2023, 2022 and 2021 amounted to $3,194, $3,976 and $3,937, respectively. The Company's employees in the U.S. receive severance benefits in the event of an involuntary termination that increase in accordance with their tenure and base salary. The Company accounts for post-employment benefits in accordance with ASC Topic No. 712, Compensation – Nonretirement Post-employment Benefits. These benefits, primarily severance, are not accrued until the amount can be reasonably estimated. Severance expenses recorded in the U.S. for the years ended December 31, 2023, 2022 and 2021, other than one-time termination benefits detailed in Note 18, were immaterial. Israeli Employees Defined Contribution Plan The Company has established a pension contribution plan with respect to Kaltura Israel's employees. Under the plan, Kaltura Israel contributed up to 6.5% of each employee's monthly salary toward the plan. Employees are entitled to amounts accumulated in the plan upon reaching retirement age, subject to any applicable law. Defined contribution pension plan expenses for the years ended December 31, 2023, 2022 and 2021 amounted to $2,397, $3,099 and $3,108, respectively. Revenue Recognition The Company recognizes revenue under Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, the Company recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. The Company applies judgment in identifying and evaluating terms and conditions in contracts which may impact revenue recognition. To determine the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements, the Company performs the following steps: 1. Identify the contract with a customer The Company considers the terms and conditions of contracts with customers and its customary business practices in identifying contracts under ASC 606. The Company determines it has a contract with a customer when the contract is approved, each party’s rights regarding the services to be transferred can be identified, payment terms for the services can be identified, it has been determined that the customer has the ability and intent to pay, and the contract has commercial substance. The Company applies judgment in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer. The Company engages in formal, written, and binding contracts with its customers that create enforceable rights and obligations between the parties and state each party’s rights regarding the license and services to be transferred and the terms of payment. The Company evaluates the probability of collection of the consideration that it is entitled to receive in exchange for the subscriptions and professional services it transfers to the customer. The Company records trade receivables and related contract liabilities for non-cancelable contracts with customers when the right to consideration is unconditional. 2. Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the goods or service either on its own or together with other resources that are readily available from the Company or from third-parties, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. The Company provides subscriptions and post-contract services ("PCS") to its Video Experience Cloud, which powers live, real-time, and on-demand video experiences. The Company provides access to its platform either as a cloud-based service ("SaaS" or "PaaS") or, less commonly, as a license to software installed on the customer's premises ("On-Prem") all together defined as subscriptions in the statement of operations. Professional Services (“PS”) consist of integration, configuration and customization activities. In some of the Company's arrangements, PS are accounted for as a separate performance obligation. However, in some of the Company’s SaaS and PaaS arrangements the Company determined that the PS are solely set up activities that do not transfer goods or services to the customer and therefore are not accounted for as a separate performance obligation. 3. Determine the transaction price The transaction price is determined based on the consideration which the Company is expected to be entitled to in exchange for transferring the promised goods or services to the customer. This transaction price is exclusive of amounts collected on behalf of third parties, such as sales tax and value-added tax. The Company rarely provides its customers with price concessions. The Company's contracts usually include a fixed amount of consideration, as well as variable consideration for overage usage that, in most cases, is not considered probable at the inception of the contract. Revenue accounted for as variable consideration for overages usage is recognized when the uncertainty is resolved, usually when the customer exceeds its committed usage threshold (i.e., overages are consumed) and the overages are invoiced. The Company rarely has contracts for which the difference between the payment date and the revenue recognition timing is more than 12 months. The primary purpose of the Company’s payment terms is to provide customers with a simple and predictable way to purchase the Company’s subscriptions, not to provide customers with financing. In addition, the Company has elected to apply the practical expedient for financing component for transactions in which the difference between the payment date and the revenue recognition timing is up to 12 months. 4. Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”). When applicable, the Company allocates the transaction price between the separate performance obligations according to their SSP, which is based on the price at which the performance obligation is sold separately. If the SSP is not observable through past transactions, the Company estimates the SSP taking into account available information, including, but not limited to, pricing practices, market conditions, and the economic life of the software. 5. Recognize revenue when or as the Company satisfies a performance obligation Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised good or service to the customer. Revenue is recognized when control of the good or services is transferred to the customer, in an amount that reflects the consideration expected to be received in exchange for those services. A customer obtains control of a good or service if it has the ability to direct the use of and obtain substantially all of the remaining benefits from the good or service. Revenue from SaaS and PaaS subscriptions is recognized ratably over the time of the subscription, beginning from the date in which the customer is granted access to the subscription. Revenue from the sale of a term license in On-Prem deals is recognized at a point in time in which the license is delivered to the customer. Revenue from post-contract services included in On-Prem projects is recognized ratably over the time of the PCS. Revenue from PS that is accounted for as a separate performance obligation is recognized upon rendering of the service. Contract Costs Some of the sales commissions and bonuses earned by the Company's employees and management are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions and bonuses for new contracts are deferred and then amortized consistently with the pattern of revenue recognition for each performance obligation for contracts for which the commissions were earned, mainly on a straight-line basis, over a period of benefit that the Company has estimated to be mainly five years. This period of benefit was determined by taking into consideration the technology's useful life. Sales bonuses for renewal contracts are deferred and then amortized on a straight-line basis over the related contractual renewal period. The Company classifies deferred costs as current or noncurrent based on the timing of when the Company expects to recognize the expense. Amortization of sales commissions are consistent with the pattern of revenue recognition of each performance obligation and are included in sales and marketing expense in the 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. There were no impairment losses recorded during the periods presented. The Company capitalizes costs incurred to fulfill its contracts when the costs relate directly to a contract and are expected to generate resources that will be used to satisfy the performance obligation under the contract and are expected to be recovered through revenues generated under the contract. Costs to fulfill contracts are expensed to cost of revenue on a straight-line basis over a period of five years which reflects the technological useful life. Cost of Revenue C ost of subscription revenue consists primarily of employee-related costs including payroll, benefits and stock-based compensation expense for operations and customer support teams, costs of cloud hosting providers and other third-party service providers, amortization of capitalized software development costs and acquired technology and allocated overhead costs. Cost of professional services consists primarily of personnel costs of our professional services organization, including payroll, benefits, and stock-based compensation expense, allocated overhead costs and other third-party service providers. Research and Development Costs Research and development costs are charged to the statements of operations as incurred, except to the extent that such costs are associated with internal-use software that qualifies for capitalization. Internal-Use Software Costs incurred to develop internal-use software are capitalized and amortized over the estimated useful life of the software, which is generally five years. In accordance with ASC Topic, 350-40, "Internal-Use Software," capitalization of costs to develop internal-use software begins when preliminary development efforts are successfully completed, the Company has committed project funding and it is probable that the project will be completed and the software will be used as intended. Costs related to the maintenance of internal-use software are expensed as incurred. The Company periodically reviews internal-use software costs to determine whether the projects will be completed, placed in service, removed from service or replaced by other internally developed or third-party software. If the asset is not expected to provide any future benefit, the asset is retired, and any unamortized cost is expensed. Capitalized internal-use software costs are recorded under property and equipment, net. When events or changes in circumstances require, the Company assesses the likelihood of recovering the cost of internal-use software. If the net book value is not expected to be fully recoverable, internal-use software would be impaired to its fair value. During the years ended December 31, 2023, 2022 and 2021, the Company capitalized $1,660, $5,115 and $4,838 of software development costs, respectively. No impairment was recorded for the years ended December 31, 2023, 2022 and 2021. Advertising Costs Advertising costs are expensed as incurred and include marketing activities, demand generation, events, public relations and brand-building activities. Advertising costs for the years ended December 31, 2023, 2022 and 2021, amounted to $3,951, $5,767 and $5,057, respectively, and are included in sales and marketing expenses in the consolidated statements of operations. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718,"Compensation - Stock Compensation" ("ASC 718"). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award is recognized as an expense over the requisite service periods in the Company's consolidated statements of operations. Service-Based Awards The Company grants stock option awards and restricted stock units (“RSUs”), that vest only based upon the satisfaction of a service condition. For RSUs with performance conditions, expenses are recognized when it is probable that the performance condition will be achieved. The probability of achievement is assessed periodically to determine whether the performance metric continues to be probable. When there is a change in the probability of achievement, any cumulative effect of the change is recognized in the period of the change and the remaining unrecognized compensation will be amortized prospectively over the respective vesting period. The Company selected the Black-Scholes option-pricing model as the most appropriate fair value method for its option awards. The option-pricing model requires a number of assumptions, of which the most significant are the fair value of its common stock, the expected stock price volatility, expected option term, risk-free interest rates and expected dividend yield. The assumptions used to determine the fair value of the option awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. For RSUs, the Company determines the grant-date fair value of the RSUs as the fair value of the Company’s common stock on the grant date. The Company recognizes compensation cost for options and stock awards that have a graded vesting schedule and contain only service condition on a straight-line basis over the requisite service period for the entire award. Forfeitures are accounted for as they occur instead of estimating the number of awards expected to be forfeited. Market-Based Awards The Company has granted three of its executives stock options that vest only upon the satisfaction of market-based conditions. The market-based conditions reflect specific prices for the Company’s common stock, which must be exceeded for each tranche of the grant to vest. For market-based awards, the Company determined the grant-date fair value utilizing a Monte Carlo simulation model, which incorporates various assumptions including expected stock price volatility, risk-free interest rates, expected exercise behavior for vested options, expected date of a qualifying event and expected form and timing of a liquidity event. The Company estimated the volatility of the common stock on the date of grant based on the weighted average historical stock price volatility of comparable publicly-traded companies. Because the option does not qualify as “plain vanilla” per SEC Staff Accounting Bulletin 107, the expected term cannot be estimated based on the simplified model described in the Bulletin. In order to address the term, the Monte Carlo simulation model includes an assumption about the price level at which vested options are expected to be exercised (the “Sub Optimal Exercise” factor). The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The rate used is based on the expected term of the option. The Company recognizes compensation expenses for the value of its market-based awards based on the accelerated attribution method over the estimated requisite service period of each of the awards. The Company has determined that there is no explicit or implicit service period for the awards, and therefore the requisite service period is based on the derived service period. The derived service period is the term calculated in the Monte Carlo valuation model as described above. The derived service period is the median duration of the simulated price paths in which the option tranche vests, which is determined by the above assumptions. Business Combination The Company accounted for business combination in accordance with ASC 805, "Business combinations". ASC 805 requires recognition of assets acquired, liabilities assumed, and any non-controlling interest at the acquisition date, measured at fair values as of that date. Any excess of the fair value of net assets acquired over purchase price and any subsequent changes in estimated contingencies are to be recorded in earnings. Acquisition related costs are expensed to the statement of operations in the period incurred. Income Taxes The Company accounts for income taxes in accordance with ASC 740, "Income Taxes". This codification prescribes the use of the asset and liability method whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and for carry-forward tax losses. Deferred taxes are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value if it is more likely than not that some portion or all of the deferred tax asset will not be realized. The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740, "Income Taxes". Accounting guidance addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the consolidated financial statements, under which a company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. Accordingly, the Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return (see also Note 11). Net Loss per Share Attributable to Common Stockholders The Company's basic net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period, without consideration of potentially dilutive securities. The diluted net loss per share is calculated by giving effect to all potentially dilutive securities outstanding for the period using the treasury share method or the if-converted method based on the nature of such securities. Diluted net loss per share is the same as basic net loss per share in periods when the effects of potentially dilutive shares of common stock are anti-dilutive. Prior to the completion of the Company's initial public offering in July 2021 (“IPO”), the Company computed net loss per share using the two-class method required for participating securities. The two-class method requires income available to common stockholder for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. The Company considered its convertible preferred stock to be participating securities as the holders of the convertible preferred stock would be entitled to dividends that would be distributed to the holders of common stock, on a pro-rata basis, assuming the conversion of all outstanding shares of convertible preferred stock into common stock. These participating securities did not contractually require the holders of such stock to participate in the Company’s losses. As such, net loss for the periods presented was not allocated to the Company’s participating securities. Concentration of Credit Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, marketable securities, restricted cash and trade receivables. The majority of the Company's and its subsidiaries' cash and cash equivalents and restricted cash are invested with major banks in Israel, the United Kingdom and the United States. Such investments in the United States may be in excess of insured limits and are not insured in other jurisdictions. However, in general, these investments may be redeemed upon demand and therefore bear minimal risk. The Company's trade receivables are geographically dispersed and derived from sales to customers mainly in the United States, Europe and Asia. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation and account monitoring procedures. Major customer data as a percentage of total revenues: The following table sets forth a customer that represented 10% or more of the Company’s total revenue in each of the periods set forth below: Year ended December 31, 2023 2022 2021 Customer A (Media and Telecom) 10.22 % *) — *) — *) Represents an amount that is lower than 10% of the Company’s total revenue.

Income Tax Disclosure [Abstract]
Income Tax Disclosure	NOTE 11: INCOME TAXES The Company's subsidiaries are separately taxed under the domestic tax laws of the jurisdiction of incorporation of each entity. Loss (income) before taxes on income is comprised as follows: Year Ended December 31, 2023 2022 2021 Domestic $ 45,625 $ 66,346 $ 75,259 Foreign (8,170) (5,719) (22,478) Loss before taxes on income $ 37,455 $ 60,627 $ 52,781 The provision for income taxes was as follows: Year Ended December 31, 2023 2022 2021 Current provision: Federal $ — $ — $ — State 83 88 65 Foreign 8,410 7,780 6,505 8,493 7,868 6,570 Deferred provision: Federal 171 — — State 247 — — Foreign — — — 418 — — Total provision for income taxes $ 8,911 $ 7,868 $ 6,570 Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. As of December 31, 2023 and 2022, the Company has provided a full valuation allowance in respect of deferred tax assets. Management currently believes that it is more likely than not that the deferred tax regarding the tax loss carry forwards and other temporary differences will not be realized in the foreseeable future in the U.S. Significant components of the Company's deferred tax assets are as follows: December 31, 2023 2022 Deferred tax assets: Net operating losses carryforward $ 69,160 $ 71,887 Disallowed business interest expense 4,023 4,760 Capitalized R&D costs 26,126 16,322 Reserves & accruals 1,486 1,489 Deferred revenue 378 283 Lease liability 829 1,009 Stock based compensation 5,823 2,710 Intercompany payable 5,498 — Other assets 77 49 Deferred tax assets before valuation allowance 113,400 98,509 Valuation allowance (101,237) (84,795) Total deferred tax assets, net of valuation allowance $ 12,163 $ 13,714 Deferred tax liabilities: Intangible Assets (970) (798) Deferred contract acquisition and fulfillment costs (7,686) (8,782) Internal use software (2,988) (3,073) Operating lease right-of-use assets (742) (923) Property and equipment — (138) Other (195) — Total gross deferred tax liabilities $ (12,581) $ (13,714) Total net deferred tax liabilities $ (418) $ — As of December 31, 2023, the U.S. parent company had a net U.S. operating loss carry forward ("NOLs") for federal income tax purposes of approximately $258,007 and U.S. state NOLs of approximately $183,555. Out of the operating losses attributed to the U.S. parent company, $143,229 were generated before January 1, 2018, and are subject to the 20-year carryforward period. The remaining $114,778 can be carried forward indefinitely but are subject to the 80% taxable income limitation. Utilization of the U.S. net operating losses above may be subject to substantial annual limitations due to the "change in ownership" provisions of the Internal Revenue Code of 1986 and similar state provisions. The annual limitation may result in the expiration of substantial net operating losses before utilization (the 80% limitation was waived for NOLs utilized in 2019 and 2020 under the CARES Act). The Company has analyzed the impact of Section 382 on its NOLs through 2020 and believes that the NOLs are not materially limited by Section 382. However, any future changes of ownership could impact the Company’s ability to utilize NOLs. A reconciliation of the Company's theoretical income tax expense to actual income tax expense is as follows: Year Ended December 31, 2023 2022 2021 Loss before tax as reported at the consolidated statement of operations $ 37,455 $ 60,627 $ 52,781 Statutory tax rate 21 % 21 % 21 % Theoretical tax benefit $ (7,866) $ (12,732) $ (11,084) Non-deductible expenses and other permanent differences 1,026 154 403 Remeasurement of warrants to Fair Value — — 3,160 Stock based compensation 2,403 2,193 3,651 Change in valuation allowance 16,842 9,745 13,232 State taxes, net of federal benefit (2,898) 4,946 (3,700) Income tax at rate other than the U.S. statutory tax rate 1,613 3,045 320 Exchange rate differences (511) 332 (100) Return to provision adjustments (1,321) — — Other (377) 185 688 Total tax expenses $ 8,911 $ 7,868 $ 6,570 On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act, a comprehensive tax law that includes significant changes to the taxation of business entities. These changes include several key tax provisions, among others: (i) a permanent reduction to the statutory federal corporate income tax rate from 35% to 21% effective for tax years beginning after December 31, 2017; (ii) a partial limitation on the tax deductibility of business interest expenses; (iii) a shift of the U.S. taxation of multinational corporations from a tax on worldwide income to a territorial system (along with certain rules designed to prevent erosion of the U.S. income tax base) and (iv) a one-time deemed repatriation tax on accumulated offshore earnings held in cash and illiquid assets, with the latter taxed at a lower rate. In addition, begging in 2022, U.S research and experimental expenditures should be capitalized and amortized ratably over a five-year period, Any such expenditures attributable to research conducted outside of the U.S must be capitalized and amortized over a-15 year period. The Israeli corporate tax rate was 23% for the years ended December 31, 2023, 2022 and 2021. However, the effective tax rate payable by a company that derives income from a "Benefited Enterprise" or a "Preferred Enterprise" (as discussed below) may be considerably less. Capital gains derived by an Israeli company are generally subject to the prevailing corporate tax rate. Tax benefits by virtue of the Law for the Encouragement of Capital Investments, 1959 ("the Investment Law"): Until tax year 2014, Kaltura Israel utilized various tax benefits by virtue of the "Benefited Enterprise" status granted to its enterprise, pursuant to the Investment Law. Kaltura Israel elected benefits under the alternative track of benefits according to which it was exempt from income tax in the first two years (from the date Kaltura Israel earned taxable income). If a dividend is distributed out of tax exempt income earned by a Benefited Enterprise the amount distributed will be subject to corporate tax at the rate that would have otherwise been applicable on the Benefited Enterprise income. Dividends paid out of income attributed to a Beneficiary Enterprise are generally subject to withholding tax at source at the rate of 15% or such lower rate as may be provided in an applicable tax treaty. As of December 31, 2023, approximately $520 was derived from tax exempt profits earned by Kaltura Israel's "Beneficiary Enterprise." The Company and its Board of Directors have determined that such tax-exempt income will not be distributed as dividends and intends to reinvest the amount of its tax-exempt income earned by Kaltura Israel. Accordingly, no provision for deferred income taxes has been provided on income attributable to Kaltura Israel's "Beneficiary Enterprise" as such income is essentially permanently reinvested. If Kaltura Israel's retained tax-exempt income is distributed, the income would be taxed at the applicable corporate tax rate as if it had not elected the alternative tax benefits under the Investment Law and an income tax liability of up to $130 would be incurred as of December 31, 2023. In 2011, new legislation amending the Investment Law was adopted. Under this new legislation, a unified corporate tax rate applied to all qualifying income generated by a "Preferred Company" through its Preferred Enterprise (as such terms are defined in the Investment Law) as of January 1, 2011. Industrial Companies under the Preferred Enterprise status according to the new law as amended in July 2013, and starting January 1, 2014 are entitled to a uniform reduced corporate tax rate of 9% in areas in Israel designated as Development Zone A and 16% elsewhere in Israel. The 2011 Amendment also provided transitional provisions to address companies already enjoying current benefits under the Investment Law. Under the transition provisions, the Company decided to irrevocably implement the new law, effective January 1, 2015. Dividends distributed from income which is attributed to a “Preferred Enterprise” will be subject to withholding tax at source at the rate of 20% or such lower rate as may be provided in an applicable tax treaty. Kaltura Israel's income from other sources is subject to tax at the regular Corporate Income rate. The Company indefinitely reinvests earnings from its foreign subsidiaries and therefore no deferred tax liability has been recognized on the basis difference created by such earnings. The Company has not provided foreign withholding taxes for any undistributed earnings of its foreign subsidiaries. Generally, in U.S. federal and state taxing jurisdictions, tax periods in which certain loss and credit carryovers are generated remain open for audit until such time as the limitation period ends for the year in which such losses or credits are utilized. Kaltura Israel received final tax assessments through 2016 while the rest of the Company's subsidiaries did not have any final tax assessments as of December 31, 2023. A reconciliation of the opening and closing amounts of total unrecognized tax benefits is as follows: Unrecognized Tax Benefits Balance as of December 31, 2020 $ 3,863 Decreases related to prior years' tax positions (107) Increases related to current years' tax positions 738 Balance as of December 31, 2021 $ 4,494 Decreases related to prior years' tax positions (313) Increases related to current years' tax positions 1,145 Balance as of December 31, 2022 5,326 Decreases related to prior years' tax positions — Increases related to current years' tax positions 1,815 Balance as of December 31, 2023 $ 7,141 The total amount of unrecognized tax benefits that would affect the effective tax rate, if recognized, was $7,141 and $5,326 as of December 31, 2023 and 2022. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2023 and 2022, the Company had accrued $373 and $467 for the payment of interest and penalties relating to unrecognized tax benefits, respectively. In addition, the Company is subject to the continuous examination of its income tax returns by the IRS and other tax authorities. The Company’s federal and state income tax returns for years subsequent to 2007 remain open to examination. In the Company’s foreign jurisdictions – Israel and the United Kingdom – the tax years subsequent to 2016 remain open to examination. The Company is currently under audit in Israel. The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. The Company currently does not expect uncertain tax positions to change significantly over the next 12 months, except in the case of settlements with tax authorities, the likelihood and timing of which is difficult to estimate.

Segment Reporting [Abstract]
Segment Reporting Disclosure	NOTE 13: REPORTABLE SEGMENTS AND GEOGRAPHICAL INFORMATION Reportable segments ASC 280, Segment Reporting, establishes standards for reporting information about operating segments. 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 in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker is its Chief Executive Officer ("CODM"). The Company's CODM does not regularly review asset information by segments and, therefore, the Company does not report asset information by segment. The Company organizes its operations in two segments: Enterprise, Education and Technology and Media and Telecom. The Enterprise, Education and Technology segment represents products related to industry solutions for education customers, and media services (except for Media and Telecom customers). The Media and Telecom segment primarily represents TV solutions that are sold to media and telecom operators. The measurement of the reportable operating segments is based on the same accounting principles applied in these financial statements, which includes certain corporate overhead allocations. Year Ended December 31, 2023 Enterprise, Education and Technology Media and Telecom Total Revenue $ 125,154 $ 50,018 $ 175,172 Gross profit $ 91,624 $ 20,610 $ 112,234 Operating expenses 150,889 Financial income, net (1,200) Provision for income taxes 8,911 Net loss $ 46,366 Year Ended December 31, 2022 Enterprise, Education and Technology Media and Telecom Total Revenue $ 120,190 $ 48,621 $ 168,811 Gross profit $ 83,812 $ 23,128 $ 106,940 Operating expenses 163,319 Financial expenses, net 4,248 Provision for income taxes 7,868 Net loss $ 68,495 Year Ended December 31, 2021 Enterprise, Education and Technology Media and Telecom Total Revenue $ 118,932 $ 46,084 $ 165,016 Gross profit $ 84,196 $ 18,506 $ 102,702 Operating expenses 135,377 Financial expenses, net 20,106 Provision for income taxes 6,570 Net loss $ 59,351 Geographical information Revenue by location is determined by the billing address of the customer.

Debt Disclosure [Abstract]
Long-Term Debt	NOTE 14: LONG-TERM LOAN In January 2021, the Company entered into a new credit agreement (the “Credit Agreement”) with an existing lender, which provides for a new senior secured term loan facility in the aggregate principal amount of $40,000 (the “Term Loan Facility”) and a new senior secured revolving credit facility in the aggregate principal amount of $10,000 (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Credit Facilities”), which subsequently and has been amended according to the Company's needs and other developments. In May 2023, the Company entered into an amendment (the "Fourth Amendment") to the then-existing Credit Agreement to replace the London Interbank Offered Rate (“LIBOR”) with the Secured Overnight Financing Rate (“SOFR”) as the benchmark rate under the Credit Agreement. Prior to the Fourth Amendment, borrowings under the Credit Agreement would bear interest, at the Company's election, at (a) the Eurodollar Rate (as defined in the Credit Agreement as in effect prior to the Fourth Amendment) plus a margin of 3.50% or (b) Alternative Base Rate (“ABR”) (as defined in the Credit Agreement) plus a margin of 2.50%. In December 2023, the Company entered into a new amendment to the then-existing Credit Agreement (the “Fifth Amendment”), which provides for a new term loan facility in the aggregate principal amount of $35,000. Commitments under the Revolving Credit Facility decreased to $25,000. Following the effectiveness of the Fifth Amendment, borrowings under the Credit Facilities bear interest, determined as follows: (a) SOFR loans accrue interest at a rate per annum equal to Term SOFR (as defined in the Credit Agreement) plus 0.10% per annum plus a margin of 2.50% (the Adjusted Term SOFR (as defined in the Credit Agreement) is subject to a 1.00% floor), and (b) ABR loans accrue interest at a rate per annum equal to the ABR plus a margin of 1.50% (ABR is equal to the highest of (i) the prime rate and (ii) the Federal Funds Effective Rate plus 0.50%, subject to a 2.00% floor). As of December 31, 2023, the current rate of interest under the Credit Facilities was equal to a rate per annum of 7.98%, consisting of 5.38% (the 3-month SOFR rate as of December 31, 2023), 0.10% credit spread adjustment and the margin of 2.50%. The Term Loan Facility is payable in consecutive quarterly installments on the last day of each fiscal quarter in an amount equal to (i) $438 for installments payable on December 31, 2023 (deferred to January 9, 2024), through September 30, 2024, (ii) $656 for installments payable on December 31, 2024 through September 30, 2025, and (iii) $1,313 for installments payable on and after December 31, 2025. The remaining unpaid balance on the Term Loan Facility is due and payable on December 21, 2026, together with accrued and unpaid interest on the principal amount to be paid to, but excluding, the payment date. Amounts outstanding under the Credit Facilities may be voluntarily prepaid at any time and from time to time, in whole or in part, without premium or penalty. Under the terms of the Credit Facilities, the Company is obligated to maintain compliance with certain financial covenants as defined therein. As of December 31, 2023, the Company met these covenants. The aggregate principal annual maturities according to the Credit Facilities agreements are as follows: Year ended December 31, 2024 $ 2,406 2025 3,281 2026 29,313 $ 35,000 The carrying amounts of the loans approximate their fair value.

Equity [Abstract]
Stockholders' Equity Note Disclosure	NOTE 15: STOCKHOLDERS' EQUITY Preferred Stock In connection with the IPO, the Company amended and restated its Certificate of Incorporation to change the authorized preferred stock to 20,000,000 shares of preferred stock, all with a par value of $0.0001 per share. Common Stock The shares of common stock confer upon their holders the right to receive notice to participate and vote in general stockholders meetings of the Company, and the right to receive dividends, if declared, and to participate in the distribution of the surplus assets of the Company upon liquidation of the Company, as more fully described in the Company's Certificate of Incorporation. In connection with the IPO, the Company amended and restated its Certificate of Incorporation to change the authorized common stock to 1,000,000,000 shares of common stock, all with a par value of $0.0001 per share. The Company has the following common stock reserved for future issuance as of December 31, 2023: December 31, 2023 Outstanding options 22,933,058 Outstanding RSUs 11,199,265 Shares reserved under 2021 Plan 3,521,137 Total 37,653,460 Equity Incentive Plans Under the Company's 2007 U.S. and Israeli Stock Option Plans ("the 2007 Plans"), options were granted to officers, directors, employees, advisors and consultants of the Company or its subsidiaries. In 2017, the Company adopted a new equity incentive plan, the "2017 Equity Incentive Plan" (the "2017 Plan" and together with the 2007 Plans, the "Old Plans"), and extended the term of the 2007 Israeli Stock Option Plan and the term of the options already granted thereunder for an additional ten-year period. Each option granted under the Old Plans is exercisable until the earlier of ten years (or 20 years if granted under the 2007 Israeli Stock Option Plan) from the date of the grant of the option. The options vest primarily over a four-year period. Any options that are forfeited or not exercised before expiration become available for future grants. In December 2020, the Company granted to three of its officers, market-based options at an exercise price of $13.34 per share. The options vest based on the achievement of specific share price targets such that 25% of the award will vest upon the fair market value of a share of common stock increasing fifty percent (50%) above the exercise price; an additional 25% of such award will vest upon the fair market value of a share increasing one-hundred percent (100%) above the exercise price; an additional 25% will vest upon the fair market value of a share increasing one-hundred and fifty percent (150%) above the exercise price; and the remaining 25% of the award will vest upon the fair market value increasing two-hundred percent (200%) above the exercise price. Following the Company’s IPO, no additional awards will be granted under the Old Plans. However, the Old Plans will continue to govern the terms and conditions of the outstanding awards previously granted under the Old Plans. Effective upon the effectiveness of the registration statement for the IPO, the Company adopted the 2021 Incentive Award Plan (the “2021 Plan”, and together with the Old Plans, the "Plans"). The 2021 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, RSUs, and other stock or cash-based awards to the Company’s officers, directors, employees, advisors, and consultants. The number of shares of common stock initially reserved for issuance under the 2021 Plan was 8,500,000 shares. in addition, certain shares of common stock subject to awards under the Old Plans, such as those subject to expirations, terminations, exercise and tax-related withholding, or failures to vest, will become available for issuance under the 2021 Plan. The number of shares of common stock available for issuance under the 2021 Plan will also include an annual increase on the first day of each fiscal year beginning on January 1, 2022, equal to the lesser of: • 5% of the aggregate number of shares of common stock outstanding on the final day of the immediately preceding calendar year; and • Such smaller number of shares of common stock as is determined by the Board of Directors. Under the 2021 Plan, the exercise price of options granted is generally at least equal to the fair market value of the Company’s common stock on the date of grant. The term of the options generally may not exceed ten years. Additionally, the exercise price of any options granted to a 10% stockholder shall not be less than 110% of the fair market value of the common stock on the date of grant, and the term of such option grant shall not exceed five years. On January 1, 2023, the number of shares of common stock authorized for issuance under the 2021 Plan automatically increased by 6,728,221 shares pursuant to the terms of the 2021 Plan. During 2023, the Company granted to its officers RSUs under the 2021 Plan which shall vest based upon achievement of certain performance targets set forth in the 2023 Executive Compensation Plan, and additional RSUs that vest in quarterly installments over a period of up to three years commencing as of January 1, 2023 with the first quarterly vesting date on April 1, 2023, subject to continued employment through the vesting dates.

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2023
Accounting Policies [Abstract]
Use of Estimates, Policy	Use of Estimates
Foreign Currency Transactions and Translations Policy	Financial Statements in U.S. Dollars The currency of the primary economic environment in which the operations of Kaltura Inc. and its subsidiaries are conducted is the U.S. dollar; thus, the dollar is the functional currency of Kaltura Inc. and its subsidiaries. Accordingly, monetary accounts maintained in currencies other than the U.S. dollar are remeasured into U.S. dollars in accordance with Statement of the Accounting Standard Codification ("ASC") 830 "Foreign Currency Matters" ("ASC 830"). All transaction gains and losses of the remeasured monetary balance sheet items are reflected in the statements of operations as financial income or expenses, as appropriate.
Consolidation, Policy	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany transactions and balances have been eliminated upon consolidation.
Cash and Cash Equivalents, Policy	Cash and Cash Equivalents Cash equivalents are short term, highly liquid investments that are readily convertible to cash with original maturities of three months or less, at the date acquired.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy	Restricted Cash Restricted cash is primarily invested in deposits held to maturity, stated at cost, which also approximates their fair value, and are used as security for the Company's liabilities. These deposits are used mainly as security for rent payments, and the Company's credit cards. Restricted cash is presented in the balance sheet as part of other assets, noncurrent.
Marketable Securities, Policy	Marketable Securities The Company accounts for investments in marketable securities in accordance with ASC No. 320, “Investments - Debt Securities”. Management determines the appropriate classification of its investments at the time of purchase and reevaluates such determinations at each balance sheet date. The Company classifies all of its debt securities as available-for-sale. Available-for-sale debt securities are carried at fair value, with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive income (loss) in shareholders’ equity. Realized gains and losses on sale of investments are included in financial expenses (income), net and are derived using the specific identification method for determining the cost of securities sold. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization together with interest on securities is included in financial income, net. The Company periodically evaluates its available-for-sale debt securities for impairment. If the amortized cost of an individual security exceeds its fair value, the Company considers its intent to sell the security or whether it is more likely than not that it will be required to sell the security before recovery of its amortized basis. If either of these criteria are met, the Company writes down the security to its fair value and records the impairment charge in financial expenses (income), net in the Consolidated Statements of Operations. If neither of these criteria are met, the Company determines whether credit loss exists. Credit loss is estimated by considering changes to the rating of the security by a rating agency, any adverse conditions specifically related to the security, as well as other factors.
Accounts Receivable	Trade Receivables
Derivatives, Policy	Derivatives and Hedging
Property, Plant and Equipment, Policy	Property and Equipment, net Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets: Years Computers and peripheral equipment 3 Office furniture and equipment 7-15 Leasehold improvements Over the shorter of the related lease period or the life of the asset
Impairment or Disposal of Long-Lived Assets, Policy	Impairment of Long-Lived Assets
Intangible Assets, Finite-Lived, Policy	Intangible Assets, net Intangible ass ets con sist primarily of customer relationships, technology and trade name. The intangible assets are amortized over their estimated useful lives in proportion to the economic benefits realized. Intangible assets consist primarily of customer relationships, technology, and trade name. Amortization for the intangible assets was recognized over the following periods: Years Customer relationships 7-9 Technology 5-8 Tradename 10
Goodwill and Intangible Assets, Goodwill, Policy	Goodwill Goodwill re presents the excess of the purchase price over the fair value of net assets acquired in business combinations using the acquisition method of accounting, which requires that the assets acquired and liabilities assumed be recorded at the date of acquisition at their respective fair values. Goodwill is subject to an impairment test at the reporting unit level at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. The Company identified two reporting units - EE&T and M&T. Goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value. An impairment loss is recognized in an amount equal to the excess. There were no impairment charges to goodwill during the periods presented.
Lessee, Leases	Leases The Company determines if an arrangement is a lease at inception. The Company currently does not have any finance leases. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The Company combines its lease payments and fixed payments for non-lease components and account for them together as a single lease component. Operating lease ROU assets also include any prepaid lease payments and lease incentives. Certain lease agreements include rental payments adjusted periodically for the consumer price index (“CPI”). The ROU and lease liability were calculated using the initial CPI and will not be subsequently adjusted, unless the liability is reassessed for other reasons. Payments for variable lease costs are expensed as incurred and not included in the operating lease ROU assets and liabilities. For short-term leases with a term of 12 months or less, operating lease ROU assets and liabilities are not recognized and the Company records lease payments in the Consolidated Statements of Operations on a straight-line basis 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 the Company’s leases is not readily determinable. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Many of the Company’s lease agreements provide one or more options to renew. When determining lease terms, the Company uses the non-cancellable period of the leases and do not assume renewals unless it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term.
Pension and Other Postretirement Plans, Nonpension Benefits, Policy	everance Pay The majority of Kaltura Israel's agreements with its employees in Israel are in accordance with section 14 of the Israeli Severance Pay Law. Upon contribution of the full amount of the employee's monthly salary and release of the policy to the employee, no additional legal obligation exists between the parties and no additional payments are made by the Company to the employee; therefore, related assets and liabilities are not presented in the balance sheet. For Kaltura Israel employees who are not subject to section 14, the Company calculated the liability for severance pay pursuant to the Severance Pay Law based on the most recent salary of these employees multiplied by the number of years of employment as of the balance sheet date. Kaltura Israel's liability for these employees is fully provided for via monthly deposits with severance pay funds, insurance policies and an accrual. The value of these deposits is recorded as an asset on the Company's balance sheet in other assets, noncurrent. Severance expenses recorded in Kaltura Israel for the years ended December 31, 2023, 2022 and 2021 amounted to $3,194, $3,976 and $3,937, respectively. The Company's employees in the U.S. receive severance benefits in the event of an involuntary termination that increase in accordance with their tenure and base salary. The Company accounts for post-employment benefits in accordance with ASC Topic No. 712, Compensation – Nonretirement Post-employment Benefits. These benefits, primarily severance, are not accrued until the amount can be reasonably estimated. Severance expenses recorded in the U.S. for the years ended December 31, 2023, 2022 and 2021, other than one-time termination benefits detailed in Note 18, were immaterial.
Pension and Other Postretirement Plans, Policy	Israeli Employees Defined Contribution Plan The Company has established a pension contribution plan with respect to Kaltura Israel's employees. Under the plan, Kaltura Israel contributed up to 6.5% of each employee's monthly salary toward the plan. Employees are entitled to amounts accumulated in the plan upon reaching retirement age, subject to any applicable law. Defined contribution pension plan expenses for the years ended December 31, 2023, 2022 and 2021 amounted to $2,397, $3,099 and $3,108, respectively.
Revenue from Contract with Customer	Revenue Recognition The Company recognizes revenue under Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, the Company recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. The Company applies judgment in identifying and evaluating terms and conditions in contracts which may impact revenue recognition. To determine the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements, the Company performs the following steps: 1. Identify the contract with a customer The Company considers the terms and conditions of contracts with customers and its customary business practices in identifying contracts under ASC 606. The Company determines it has a contract with a customer when the contract is approved, each party’s rights regarding the services to be transferred can be identified, payment terms for the services can be identified, it has been determined that the customer has the ability and intent to pay, and the contract has commercial substance. The Company applies judgment in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer. The Company engages in formal, written, and binding contracts with its customers that create enforceable rights and obligations between the parties and state each party’s rights regarding the license and services to be transferred and the terms of payment. The Company evaluates the probability of collection of the consideration that it is entitled to receive in exchange for the subscriptions and professional services it transfers to the customer. The Company records trade receivables and related contract liabilities for non-cancelable contracts with customers when the right to consideration is unconditional. 2. Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the goods or service either on its own or together with other resources that are readily available from the Company or from third-parties, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. The Company provides subscriptions and post-contract services ("PCS") to its Video Experience Cloud, which powers live, real-time, and on-demand video experiences. The Company provides access to its platform either as a cloud-based service ("SaaS" or "PaaS") or, less commonly, as a license to software installed on the customer's premises ("On-Prem") all together defined as subscriptions in the statement of operations. Professional Services (“PS”) consist of integration, configuration and customization activities. In some of the Company's arrangements, PS are accounted for as a separate performance obligation. However, in some of the Company’s SaaS and PaaS arrangements the Company determined that the PS are solely set up activities that do not transfer goods or services to the customer and therefore are not accounted for as a separate performance obligation. 3. Determine the transaction price The transaction price is determined based on the consideration which the Company is expected to be entitled to in exchange for transferring the promised goods or services to the customer. This transaction price is exclusive of amounts collected on behalf of third parties, such as sales tax and value-added tax. The Company rarely provides its customers with price concessions. The Company's contracts usually include a fixed amount of consideration, as well as variable consideration for overage usage that, in most cases, is not considered probable at the inception of the contract. Revenue accounted for as variable consideration for overages usage is recognized when the uncertainty is resolved, usually when the customer exceeds its committed usage threshold (i.e., overages are consumed) and the overages are invoiced. The Company rarely has contracts for which the difference between the payment date and the revenue recognition timing is more than 12 months. The primary purpose of the Company’s payment terms is to provide customers with a simple and predictable way to purchase the Company’s subscriptions, not to provide customers with financing. In addition, the Company has elected to apply the practical expedient for financing component for transactions in which the difference between the payment date and the revenue recognition timing is up to 12 months. 4. Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”). When applicable, the Company allocates the transaction price between the separate performance obligations according to their SSP, which is based on the price at which the performance obligation is sold separately. If the SSP is not observable through past transactions, the Company estimates the SSP taking into account available information, including, but not limited to, pricing practices, market conditions, and the economic life of the software. 5. Recognize revenue when or as the Company satisfies a performance obligation Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised good or service to the customer. Revenue is recognized when control of the good or services is transferred to the customer, in an amount that reflects the consideration expected to be received in exchange for those services. A customer obtains control of a good or service if it has the ability to direct the use of and obtain substantially all of the remaining benefits from the good or service. Revenue from SaaS and PaaS subscriptions is recognized ratably over the time of the subscription, beginning from the date in which the customer is granted access to the subscription. Revenue from the sale of a term license in On-Prem deals is recognized at a point in time in which the license is delivered to the customer. Revenue from post-contract services included in On-Prem projects is recognized ratably over the time of the PCS. Revenue from PS that is accounted for as a separate performance obligation is recognized upon rendering of the service. Contract Costs Some of the sales commissions and bonuses earned by the Company's employees and management are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions and bonuses for new contracts are deferred and then amortized consistently with the pattern of revenue recognition for each performance obligation for contracts for which the commissions were earned, mainly on a straight-line basis, over a period of benefit that the Company has estimated to be mainly five years. This period of benefit was determined by taking into consideration the technology's useful life. Sales bonuses for renewal contracts are deferred and then amortized on a straight-line basis over the related contractual renewal period. The Company classifies deferred costs as current or noncurrent based on the timing of when the Company expects to recognize the expense. Amortization of sales commissions are consistent with the pattern of revenue recognition of each performance obligation and are included in sales and marketing expense in the 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. There were no impairment losses recorded during the periods presented. The Company capitalizes costs incurred to fulfill its contracts when the costs relate directly to a contract and are expected to generate resources that will be used to satisfy the performance obligation under the contract and are expected to be recovered through revenues generated under the contract. Costs to fulfill contracts are expensed to cost of revenue on a straight-line basis over a period of five years which reflects the technological useful life.
Cost of Goods and Service	Cost of Revenue C ost of subscription revenue consists primarily of employee-related costs including payroll, benefits and stock-based compensation expense for operations and customer support teams, costs of cloud hosting providers and other third-party service providers, amortization of capitalized software development costs and acquired technology and allocated overhead costs. Cost of professional services consists primarily of personnel costs of our professional services organization, including payroll, benefits, and stock-based compensation expense, allocated overhead costs and other third-party service providers.
Research and Development Expense, Policy	Research and Development Costs Research and development costs are charged to the statements of operations as incurred, except to the extent that such costs are associated with internal-use software that qualifies for capitalization.
Internal Use Software, Policy	Internal-Use Software Costs incurred to develop internal-use software are capitalized and amortized over the estimated useful life of the software, which is generally five years. In accordance with ASC Topic, 350-40, "Internal-Use Software," capitalization of costs to develop internal-use software begins when preliminary development efforts are successfully completed, the Company has committed project funding and it is probable that the project will be completed and the software will be used as intended. Costs related to the maintenance of internal-use software are expensed as incurred. The Company periodically reviews internal-use software costs to determine whether the projects will be completed, placed in service, removed from service or replaced by other internally developed or third-party software. If the asset is not expected to provide any future benefit, the asset is retired, and any unamortized cost is expensed. Capitalized internal-use software costs are recorded under property and equipment, net. When events or changes in circumstances require, the Company assesses the likelihood of recovering the cost of internal-use software. If the net book value is not expected to be fully recoverable, internal-use software would be impaired to its fair value. During the years ended December 31, 2023, 2022 and 2021, the Company capitalized $1,660, $5,115 and $4,838 of software development costs, respectively. No impairment was recorded for the years ended December 31, 2023, 2022 and 2021.
Advertising Cost	Advertising Costs Advertising costs are expensed as incurred and include marketing activities, demand generation, events, public relations and brand-building activities. Advertising costs for the years ended December 31, 2023, 2022 and 2021, amounted to $3,951, $5,767 and $5,057, respectively, and are included in sales and marketing expenses in the consolidated statements of operations.
Share-Based Payment Arrangement	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718,"Compensation - Stock Compensation" ("ASC 718"). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award is recognized as an expense over the requisite service periods in the Company's consolidated statements of operations. Service-Based Awards The Company grants stock option awards and restricted stock units (“RSUs”), that vest only based upon the satisfaction of a service condition. For RSUs with performance conditions, expenses are recognized when it is probable that the performance condition will be achieved. The probability of achievement is assessed periodically to determine whether the performance metric continues to be probable. When there is a change in the probability of achievement, any cumulative effect of the change is recognized in the period of the change and the remaining unrecognized compensation will be amortized prospectively over the respective vesting period. The Company selected the Black-Scholes option-pricing model as the most appropriate fair value method for its option awards. The option-pricing model requires a number of assumptions, of which the most significant are the fair value of its common stock, the expected stock price volatility, expected option term, risk-free interest rates and expected dividend yield. The assumptions used to determine the fair value of the option awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. For RSUs, the Company determines the grant-date fair value of the RSUs as the fair value of the Company’s common stock on the grant date. The Company recognizes compensation cost for options and stock awards that have a graded vesting schedule and contain only service condition on a straight-line basis over the requisite service period for the entire award. Forfeitures are accounted for as they occur instead of estimating the number of awards expected to be forfeited. Market-Based Awards The Company has granted three of its executives stock options that vest only upon the satisfaction of market-based conditions. The market-based conditions reflect specific prices for the Company’s common stock, which must be exceeded for each tranche of the grant to vest. For market-based awards, the Company determined the grant-date fair value utilizing a Monte Carlo simulation model, which incorporates various assumptions including expected stock price volatility, risk-free interest rates, expected exercise behavior for vested options, expected date of a qualifying event and expected form and timing of a liquidity event. The Company estimated the volatility of the common stock on the date of grant based on the weighted average historical stock price volatility of comparable publicly-traded companies. Because the option does not qualify as “plain vanilla” per SEC Staff Accounting Bulletin 107, the expected term cannot be estimated based on the simplified model described in the Bulletin. In order to address the term, the Monte Carlo simulation model includes an assumption about the price level at which vested options are expected to be exercised (the “Sub Optimal Exercise” factor). The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The rate used is based on the expected term of the option. The Company recognizes compensation expenses for the value of its market-based awards based on the accelerated attribution method over the estimated requisite service period of each of the awards. The Company has determined that there is no explicit or implicit service period for the awards, and therefore the requisite service period is based on the derived service period. The derived service period is the term calculated in the Monte Carlo valuation model as described above. The derived service period is the median duration of the simulated price paths in which the option tranche vests, which is determined by the above assumptions.
Business Combinations Policy	Business Combination The Company accounted for business combination in accordance with ASC 805, "Business combinations". ASC 805 requires recognition of assets acquired, liabilities assumed, and any non-controlling interest at the acquisition date, measured at fair values as of that date. Any excess of the fair value of net assets acquired over purchase price and any subsequent changes in estimated contingencies are to be recorded in earnings. Acquisition related costs are expensed to the statement of operations in the period incurred.
Income Tax, Policy	Income Taxes The Company accounts for income taxes in accordance with ASC 740, "Income Taxes". This codification prescribes the use of the asset and liability method whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and for carry-forward tax losses. Deferred taxes are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value if it is more likely than not that some portion or all of the deferred tax asset will not be realized. The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740, "Income Taxes". Accounting guidance addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the consolidated financial statements, under which a company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. Accordingly, the Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return (see also Note 11).
Earnings Per Share, Policy	Net Loss per Share Attributable to Common Stockholders The Company's basic net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period, without consideration of potentially dilutive securities. The diluted net loss per share is calculated by giving effect to all potentially dilutive securities outstanding for the period using the treasury share method or the if-converted method based on the nature of such securities. Diluted net loss per share is the same as basic net loss per share in periods when the effects of potentially dilutive shares of common stock are anti-dilutive. Prior to the completion of the Company's initial public offering in July 2021 (“IPO”), the Company computed net loss per share using the two-class method required for participating securities. The two-class method requires income available to common stockholder for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. The Company considered its convertible preferred stock to be participating securities as the holders of the convertible preferred stock would be entitled to dividends that would be distributed to the holders of common stock, on a pro-rata basis, assuming the conversion of all outstanding shares of convertible preferred stock into common stock. These participating securities did not contractually require the holders of such stock to participate in the Company’s losses. As such, net loss for the periods presented was not allocated to the Company’s participating securities.
Concentration Risk, Credit Risk, Policy	Concentration of Credit Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, marketable securities, restricted cash and trade receivables. The majority of the Company's and its subsidiaries' cash and cash equivalents and restricted cash are invested with major banks in Israel, the United Kingdom and the United States. Such investments in the United States may be in excess of insured limits and are not insured in other jurisdictions. However, in general, these investments may be redeemed upon demand and therefore bear minimal risk. The Company's trade receivables are geographically dispersed and derived from sales to customers mainly in the United States, Europe and Asia. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation and account monitoring procedures. Major customer data as a percentage of total revenues: The following table sets forth a customer that represented 10% or more of the Company’s total revenue in each of the periods set forth below: Year ended December 31, 2023 2022 2021 Customer A (Media and Telecom) 10.22 % *) — *) — *) Represents an amount that is lower than 10% of the Company’s total revenue.
Fair Value Measurement, Policy	Fair Value of Financial Instruments ASC 820, "Fair Value Measurements and Disclosures", defines fair value as the price that would be received to sell an asset or paid to transfer a liability (i.e., the "exit price") in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches. ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. As a basis for considering such assumptions, ASC 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Valuations based on quoted prices in active markets for identical assets that the Company has the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2 - Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The carrying amounts of cash and cash equivalents, restricted cash, trade receivables, prepaid expenses and other current assets, employees and payroll accruals, trade payables, accrued expenses and other current liabilities, current portion of long-term loans and current portion of long-term lease approximate their fair value due to the short-term maturities of such instruments.
Commitments and Contingencies, Policy	Legal Contingencies
New Accounting Pronouncements, Policy	Recently Adopted Pronouncements As an "emerging growth company," the Jumpstart Our Business Startups Act ("JOBS Act") allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act. The adoption dates discussed below reflect this election. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The Company adopted this guidance using modified retrospective approach, effective on January 1, 2023. The adoption did not have a material effect on its consolidated financial statements.
Recent Accounting Guidance Not Yet Adopted [Policy Text Block]	Recent Accounting Guidance Not Yet Adopted In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires to disclose significant segment expenses and other segment items on an annual and interim basis and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard. In December 2023, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes - Improvements to Income Tax Disclosures” requiring enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. This ASU is effective for fiscal years beginning after December 15, 2024 on a prospective basis and retrospective application is permitted. The Company is currently evaluating the impact of the adoption of this standard.
