Accounting Policies [Abstract]
Presentation and Summary of Significant Accounting Policies	NOTE 2. PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Preparation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial statements and the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not contain all information and footnotes required by GAAP for annual financial statements. Such unaudited condensed consolidated financial statements and accompanying notes are the representations of the Company’s management, who is responsible for their integrity and objectivity. The information included in this Form 10-Q should be read in conjunction with the information included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on March 18, 2019. Interim results for the three and six months ended June 30, 2019 are not necessarily indicative of the results the Company will have for the full year ending December 31, 2019. The accompanying condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which are normal and recurring, necessary to fairly state its financial position, results of operations and cash flows. All significant intercompany transactions have been eliminated in consolidation. The financial data and the other information disclosed in these notes to the condensed consolidated financial statements reflected in the three month period presented are unaudited. The December 31, 2018 balance sheet included herein was derived from the audited financial statements but does not include all disclosures or notes required by GAAP for complete financial statements. Liquidity and Capital Resources During 2018 and 2017, the Company generated negative cash flows from operations of $42,227 and $31,911, respectively, and incurred net losses of $61,104 and $59,601, respectively. In the six months ended June 30, 2019, the Company generated negative cash flow from operations of $16,606 and incurred a net loss of $32,997. Also, the Company had an accumulated deficit of $203,408 as of June 30, 2019. Historically, the Company has satisfied its capital needs with the net proceeds from its sales of equity securities, its issuance of convertible debt, and the exercise of common stock warrants. In June 2018, the Company raised net proceeds of $32,780 through an underwritten offering of its common stock, and in the first six months of 2019, the Company raised net proceeds of $12,215 through sales of its common stock under an Equity Distribution Agreement dated June 1, 2018 (the “Equity Distribution Agreement”). The Company expects to continue to generate net losses for the foreseeable future as it makes significant investments in developing and selling its products and services. Also, the Company will continue to evaluate potential acquisitions of, or investments in, companies or technologies that complement its business, which acquisitions may require the use of cash. Management believes that the Company’s existing balances of cash, cash equivalents and marketable securities, which totaled $45,273 as of June 30, 2019, will be sufficient to meet its anticipated cash requirements for at least twelve months from the date that these financial statements are issued. However, the Company’s does not expect that its current cash, cash equivalents and marketable securities will be sufficient to support the development of its business to the point at which the Company has positive cash flows from operations, particularly if it uses cash to finance any acquisitions or investments in the future. The Company plans to meet its future needs for additional capital through equity and/or debt Use of Accounting Estimates The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the accompanying condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The principal estimates relate to revenue recognition, allowance for doubtful accounts, the valuation of stock awards and stock warrants, income taxes, and the allocation of net assets acquired from business acquisitions as well as contingent consideration, where applicable. Actual results could differ from those estimates. Significant Customers The Company’s top ten customers accounted for approximately 25.9% and 24.9% of the Company’s net revenues for the three and six months ended June 30, 2019, respectively. The Company’s top ten customers accounted for approximately 49.7% and 52.1% of the Company’s net revenues for the three and six months ended June 30, 2018, respectively. No individual customer accounted for 10% or more of the Company’s net revenues for the three and six months ended June 30, 2019. Significant Accounting Policies During the six months ended June 30, 2019, there have been no material changes in the Company’s significant accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2018. Recently Adopted Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force) In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash Recently Issued Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients The Company will apply the new revenue standard on a modified retrospective basis with an adjustment to retained earnings to recognize the cumulative effect of adoption. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement

BUSINESS COMBINATIONS Acquisition of Performance Bridge On August 21, 2018, the Company acquired all of the outstanding capital stock of Performance Bridge by means of a merger of an indirect, wholly owned subsidiary of the Company with and into Performance Bridge, with Performance Bridge surviving the merger as an indirect, wholly owned subsidiary of the Company. The Company paid initial consideration of $5,158 and paid a total of $3,909 in additional contingent earnout amounts based on the achievement of certain revenue milestones by Performance Bridge in its 2018 fiscal year. The initial consideration was comprised of $1,220 paid in cash and the issuance of 349,072 shares of the Company’s common stock, valued at $3,938 based on the Company’s closing stock price on August 21, 2018. The initial consideration was subject to adjustment based on a final calculation of Performance Bridge’s net assets at closing, which was completed in the first quarter of 2019 and resulted in the issuance to the former stockholder of Performance Bridge of an additional 6,482 shares of common stock valued at $34 based on the closing price of the Company’s common stock on January 25, 2019, which was the date both parties agreed upon the final calculation of the adjustment. A portion of the initial consideration, consisting of $120 in cash and 34,335 shares of common stock, was deposited into a third-party escrow account at closing and will be held in such account until August 21, 2020, to secure certain indemnification and other obligations of the former stockholder of Performance Bridge. The additional earnout consideration was comprised of $883 in cash and 574,231 shares of the Company’s common stock, valued at $3,026 based on the closing price of the Company’s common stock on March 28, 2019, which were paid and issued to the former stockholder of Performance Bridge in the second quarter of 2019. The acquisition of Performance Bridge has expanded the Company’s media agency offerings of comprehensive podcast solutions.

Acquisition of Wazee Digital, Inc. On August 31, 2018, the Company acquired all of the outstanding capital stock of Wazee Digital by means of a merger of a wholly owned subsidiary of the Company with and into Wazee Digital, with Wazee Digital surviving the merger as a wholly owned subsidiary of the Company. The Company paid an aggregate purchase price of $12,552, comprised of $7,423 paid in cash and the issuance of a total of 491,157 shares of the Company’s common stock, valued at $5,129 based on the Company’s closing stock price on August 31, 2018. A portion of the consideration, consisting of $925 in cash and 60,576 shares of common stock, was deposited into a third-party escrow account at closing and will be held in such account to secure certain indemnification and other obligations of the former stockholders of Wazee Digital. A portion of such escrowed consideration was released in March 2019, and the balance will be held in such account until August 31, 2020. The acquisition of Wazee Digital has expanded the Company’s offerings to include digital content management and licensing solutions. The following table summarizes the fair value of the purchase price consideration for the acquisition of Wazee Digital: Acquisition consideration Amount Cash consideration at closing $ 7,423 Equity consideration at closing 5,129 Total $ 12,552 The following is an allocation of the purchase price as of the August 31, 2018 closing date under the acquisition method of accounting and is preliminary as to the determination of deferred taxes as the information is not available at the time of this filing. The purchase price allocation is based upon an estimate of the fair value of the assets acquired and the liabilities assumed by the Company in the acquisition: Preliminary purchase price allocation: Amount Cash $ 975 Accounts receivable 2,396 Prepaid and other current assets 376 Property and equipment 292 Intangible assets 13,300 Accounts payable (825 ) Accrued expenses and other current liabilities (3,516 ) Accrued compensation (850 ) Other long-term liabilities (700 ) Identifiable net assets acquired $ 11,448 Goodwill 1,104 Total purchase price $ 12,552 The following table presents details of the acquired intangible assets of Wazee Digital: Estimated Useful Life (in years) Fair Value Developed technology 5.0 $ 9,100 Customer relationships 5.0 4,200 Total intangible assets $ 13,300 Acquisition of Machine Box, Inc. On September 6, 2018, the Company acquired all of the outstanding capital stock of Machine Box, Inc. (“Machine Box”) by means of a merger of a wholly owned subsidiary of the Company with and into Machine Box, with Machine Box surviving the merger as a wholly owned subsidiary of the Company. The Company paid initial consideration of $1,484, and agreed to pay up to an additional $3,000 in contingent amounts if Machine Box achieves certain technical development and integration milestones within 12 months after the closing of the acquisition, a portion of which was paid in the first six months of 2019, as discussed below. The initial consideration was comprised of $423 paid in cash and issuance of a total of 128,300 shares of the Company’s common stock, valued at $1,061 based on the Company’s closing stock price on September 6, 2018, of which $80 in cash and 26,981 shares of common stock were held back from payment and issuance by the Company until September 6, 2020, to secure certain indemnification and other obligations of the former stockholders of Machine Box. The additional contingent payments (if earned) will be comprised of 20% cash and 80% shares of the Company’s common stock. The fair value of the contingent amount totaled $2,880 and is treated as compensation expense for post-combination services as payment of such amount is conditioned upon the continued employment of certain key employees of Machine Box in addition to the achievement of certain performance milestones by Machine Box. The preliminary fair value of the contingent amount was determined using a probability-weighted expected payment model. This expense is being recognized as research and development expense over three separate intervals tied to the specific performance milestones during the twelve months following the acquisition. The Company recorded compensation expense of $453 and $1,333 in research and development expense in connection with the additional contingent amounts in the three and six months ended June 30, 2019, respectively. In March 2019, the Company determined that Machine Box had achieved the technical development and integration milestones required to be completed as of March 6, 2019 and, as a result, the former Machine Box stockholders became entitled to receive an aggregate of $200 in cash and an aggregate of 135,583 shares of the Company’s common stock, valued at $880 based on the closing price of the Company’s common stock on March 6, 2019. In March 2019, the Company paid to the former Machine Box stockholders an aggregate of $160 in cash and issued to them an aggregate of 108,469 shares of the Company’s common stock. The remaining $40 in cash and 27,114 shares of common stock were held back from payment and issuance by the Company until September 6, 2020, to secure certain indemnification and other obligations of the former stockholders of Machine Box. The value of the common stock that was held back was recorded to additional paid-in capital. In June 2019, the Company determined that Machine Box had achieved the technical development and integration milestones required to be completed as of June 6, 2019 and, as a result, the former Machine Box stockholders became entitled to receive an aggregate of $200 in cash and an aggregate of 97,082 shares of the Company’s common stock, valued at $808 based on the closing price of the Company’s common stock on June 6, 2019. The Company issued to the former Machine Box stockholders an aggregate of 77,666 shares of the Company’s common stock in June 2019, and paid to them an aggregate of $160 in cash in July 2019. The remaining $40 in cash and 19,416 shares of common stock were held back from payment and issuance by the Company until September 6, 2020, to secure certain indemnification and other obligations of the former stockholders of Machine Box. The value of the common stock that was held back was recorded to additional paid-in capital. Machine Box is a developer of state-of-the-art machine learning technologies, which have enhanced the Company’s aiWARE platform capabilities. The following table summarizes the fair value of the initial purchase price consideration for the acquisition of Machine Box: Acquisition consideration Amount Cash consideration at closing $ 423 Equity consideration at closing 1,061 Total $ 1,484 The following is an allocation of the purchase price as of the September 6, 2018 closing date under the acquisition method of accounting and is preliminary as to the determination of deferred taxes as the information is not available at the time of this filing. The purchase price allocation is based upon an estimate of the fair value of the assets acquired and the liabilities assumed by the Company in the acquisition: Preliminary purchase price allocation: Amount Cash $ 25 Intangible assets 700 Accrued expenses (375 ) Identifiable net assets acquired $ 350 Goodwill 1,134 Total purchase price $ 1,484 The following table presents details of the acquired intangible assets of Machine Box: Estimated Useful Life (in years) Fair Value Developed technology 5.0 $ 500 Trademarks and tradenames 2.3 100 Noncompete agreement 3.0 100 Total intangible assets $ 700 Assumptions in the Allocations of Purchase Price Management prepared the purchase price allocations for the acquired businesses, and in doing so considered or relied in part upon a report of a third party valuation expert to calculate the fair value of certain acquired assets and liabilities of each acquired business, which would primarily include identifiable intangible assets and the contingent earn-out amounts. Determining the fair value of assets and liabilities requires management to make significant estimates and assumptions which are preliminary and subject to change upon finalization of the valuation analysis. The goodwill recognized is the excess of the purchase price over the fair value of net assets acquired. Certain liabilities and deferred taxes included in the purchase price allocations are based on management's best estimates of the amounts to be paid or settled and based on information available at the time the purchase price allocations were prepared. Updates to and/or completion of the Company’s evaluation of certain income tax positions may result in changes to the recorded amounts of assets and liabilities, with corresponding adjustments to goodwill amounts in subsequent periods. The Company does not expect to deduct any of the acquired goodwill for tax purposes.

Financial Instruments	NOTE 5. FINANCIAL INSTRUMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs, the first two of which are considered observable and the last unobservable, that may be used to measure fair value, as follows: • Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2—inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; 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; or • Level 3—unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company classifies its cash, cash equivalents and marketable securities within Level 1 or Level 2 of the fair value hierarchy on the basis of valuations using quoted market prices or alternate pricing sources and models utilizing market observable inputs, respectively. The Company’s money market funds are valued based on quoted prices for the specific securities in an active market and are therefore classified as Level 1. The Company’s government securities and corporate debt securities are valued on the basis of valuations provided by third-party pricing services, as derived from such services’ pricing models, and are therefore classified as Level 2. As of June 30, 2019, the Company has not made any adjustments to the prices obtained from its third-party pricing providers. Cash and Cash Equivalents and Marketable Securities The Company’s money market funds and marketable securities are categorized as Level 1 and 2, respectively, within the fair value hierarchy. The following table shows the cost, gross unrealized losses and fair value, with a breakdown by significant investment category, of the Company’s cash and cash equivalents and marketable securities as of June 30, 2019: Gross Cash and Unrealized Fair Cash Marketable Cost Losses Value Equivalents Securities Cash $ 16,258 $ — $ 16,258 $ 16,258 $ — Level 1: Money market funds 24,017 — 24,017 24,017 — Level 2: Corporate debt securities 4,998 — 4,998 — 4,998 Total $ 45,273 $ — $ 45,273 $ 40,275 $ 4,998 As of December 31, 2018, the Company’s cash and cash equivalents and marketable securities balances were as follows: Gross Cash and Unrealized Fair Cash Marketable Cost Losses Value Equivalents Securities Cash $ 13,337 $ — $ 13,337 $ 13,337 $ — Level 1: Money market funds 24,202 — 24,202 24,202 — Level 2: U.S. government securities 2,500 (2 ) 2,498 — 2,498 Corporate debt securities 11,113 (46 ) 11,067 — 11,067 Subtotal 13,613 (48 ) 13,565 — 13,565 Total $ 51,152 $ (48 ) $ 51,104 $ 37,539 $ 13,565 The Company had no marketable securities that have been in a continuous unrealized loss position for less than 12 months and for 12 months or greater as of June 30, 2019. The following tables show information about the Company’s marketable securities that have been in a continuous unrealized loss position for less than 12 months and for 12 months or greater as of December 31, 2018: December 31, 2018 Continuous Unrealized Losses Less than 12 Months 12 Months or Greater Total Fair value of marketable securities $ 13,565 $ — $ 13,565 Unrealized losses $ (48 ) $ — $ (48 ) All marketable securities held by the Company as of June 30, 2019 will mature in one year or less. The Company may sell certain of its marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration and duration management. The Company typically invests in highly-rated securities, and its investment policy generally limits the amounts that may be invested with any one issuer. The policy generally requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss. Fair values were determined for each individual security in the securities portfolio. Stock Warrants All of the Company’s outstanding stock warrants are categorized as Level 3 within the fair value hierarchy. Stock warrants have been recorded at their fair value using either a probability weighted expected return model or the Black-Scholes option-pricing model. These models incorporate contractual terms, maturity, risk-free interest rates and volatility. The value of the Company’s stock warrants would increase if a higher risk-free interest rate was used, and would decrease if a lower risk-free interest rate was used. Similarly, a higher volatility assumption would increase the value of the stock warrants, and a lower volatility assumption would decrease the value of the stock warrants. The development and determination of the unobservable inputs for Level 3 fair value measurements and fair value calculations are the responsibility of the Company’s management with the assistance of a third-party valuation specialist. In April 2018, in connection with the advisory agreement between the Company and a financial advisory firm, the Company issued such firm a five-year warrant to purchase up to 20,000 shares of the Company’s common stock (“April 2018 Warrant”). The April 2018 Warrant was fully vested and exercisable upon issuance and has an exercise price of $11.73 per share. The Company recorded this stock warrant at its fair value using the Black-Scholes option-pricing model. The holder is able to redeem the warrant for a number of shares having a value equal to the in-the-money value of the warrant. The Company recorded the fair value of the warrant as a liability upon issuance, and such fair value is remeasured as of the end of each reporting period. The April 2018 Warrant was outstanding at June 30, 2019. The following table summarizes quantitative information with respect to the significant unobservable inputs that were used to value the April 2018 Warrant: June 30, 2019 December 31, 2018 Volatility 70 % 70 % Risk-free rate 1.76 % 2.51 % Term 3.75 years 4.25 years The following table represents a roll-forward of the fair value of the April 2018 Warrant, which was recorded within other accrued liabilities in the accompanying condensed consolidated balance sheet at June 30, 2019: Balance, December 31, 2018 $ 23 Change in fair value 50 Balance, June 30, 2019 $ 73 Adjustments to the fair value of the April 2018 Warrant were recorded in other income, net in the Company’s consolidated statement of operations and comprehensive loss for the three and six months ended June 30, 2019. There were no transfers between Level 1, Level 2 or Level 3 financial instruments in the six months ended June 30, 2019.

STOCK PLANS Stock-Based Compensation During six months ended June 30, 2019, the Company granted options to purchase an aggregate of 555,346 shares of its common stock that are subject to time-based vesting conditions (“Time-Based Options”), and options to purchase an aggregate of 1,545,849 shares of its common stock that are subject to performance-based vesting conditions (“Performance Options”). All Time-Based Options granted during the six months ended June 30, 2019 will vest over a period of four years. All Performance Options granted during the six months ended June 30, 2019 will become exercisable in three equal tranches based on the achievement of market price goals for the Company’s common stock of $49.15 per share, $98.31 per share and $196.62 per share, respectively. For each tranche to become exercisable, the closing price per share of the Company’s common stock must meet or exceed the applicable stock price goal for a period of 30 consecutive trading days. The Company valued the Time-Based Options using the Black-Scholes Merton option pricing model. The following assumptions were used to compute the grant date fair values of the Time-Based Options granted during the six months ended June 30, 2019: Expected term (in years) 6.0 - 6.1 Expected volatility 66% - 68% Risk-free interest rate 1.8% - 2.5% Expected dividend yield — The Company valued the Performance Options using a Monte Carlo simulation model.

Presentation and Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Preparation	Basis of Presentation and Preparation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial statements and the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not contain all information and footnotes required by GAAP for annual financial statements. Such unaudited condensed consolidated financial statements and accompanying notes are the representations of the Company’s management, who is responsible for their integrity and objectivity. The information included in this Form 10-Q should be read in conjunction with the information included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on March 18, 2019. Interim results for the three and six months ended June 30, 2019 are not necessarily indicative of the results the Company will have for the full year ending December 31, 2019. The accompanying condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which are normal and recurring, necessary to fairly state its financial position, results of operations and cash flows. All significant intercompany transactions have been eliminated in consolidation. The financial data and the other information disclosed in these notes to the condensed consolidated financial statements reflected in the three month period presented are unaudited. The December 31, 2018 balance sheet included herein was derived from the audited financial statements but does not include all disclosures or notes required by GAAP for complete financial statements.
Liquidity and Capital Resources	Liquidity and Capital Resources During 2018 and 2017, the Company generated negative cash flows from operations of $42,227 and $31,911, respectively, and incurred net losses of $61,104 and $59,601, respectively. In the six months ended June 30, 2019, the Company generated negative cash flow from operations of $16,606 and incurred a net loss of $32,997. Also, the Company had an accumulated deficit of $203,408 as of June 30, 2019. Historically, the Company has satisfied its capital needs with the net proceeds from its sales of equity securities, its issuance of convertible debt, and the exercise of common stock warrants. In June 2018, the Company raised net proceeds of $32,780 through an underwritten offering of its common stock, and in the first six months of 2019, the Company raised net proceeds of $12,215 through sales of its common stock under an Equity Distribution Agreement dated June 1, 2018 (the “Equity Distribution Agreement”). The Company expects to continue to generate net losses for the foreseeable future as it makes significant investments in developing and selling its products and services. Also, the Company will continue to evaluate potential acquisitions of, or investments in, companies or technologies that complement its business, which acquisitions may require the use of cash. Management believes that the Company’s existing balances of cash, cash equivalents and marketable securities, which totaled $45,273 as of June 30, 2019, will be sufficient to meet its anticipated cash requirements for at least twelve months from the date that these financial statements are issued. However, the Company’s does not expect that its current cash, cash equivalents and marketable securities will be sufficient to support the development of its business to the point at which the Company has positive cash flows from operations, particularly if it uses cash to finance any acquisitions or investments in the future. The Company plans to meet its future needs for additional capital through equity and/or debt
Use of Accounting Estimates	Use of Accounting Estimates The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the accompanying condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The principal estimates relate to revenue recognition, allowance for doubtful accounts, the valuation of stock awards and stock warrants, income taxes, and the allocation of net assets acquired from business acquisitions as well as contingent consideration, where applicable. Actual results could differ from those estimates.
Significant Customers	Significant Customers The Company’s top ten customers accounted for approximately 25.9% and 24.9% of the Company’s net revenues for the three and six months ended June 30, 2019, respectively. The Company’s top ten customers accounted for approximately 49.7% and 52.1% of the Company’s net revenues for the three and six months ended June 30, 2018, respectively. No individual customer accounted for 10% or more of the Company’s net revenues for the three and six months ended June 30, 2019.
