Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes The Company recorded an income tax benefit of $0.3 million and $0.5 million for the three and six months ended June 30, 2019, respectively. The Company recorded an income tax benefit of $4,000 and an income tax provision of $0.3 million during the three and six months ended June 30, 2018, respectively. The decrease in the Company’s income tax provision for the three and six months ended June 30, 2019, relative to the respective prior periods, were due to additional foreign losses benefited and a partial release of the valuation allowance as a result of the Usabilla acquisition. The Company regularly evaluates the realizability of its net deferred tax assets based on all available evidence, both positive and negative. The realization of net deferred tax assets is dependent on several factors, including the likelihood and amount, if any, of future taxable income in relevant jurisdictions during periods in which those temporary differences become deductible. As of June 30, 2019, the Company continues to maintain a full valuation allowance on its deferred tax assets that are not realizable on a more likely than not basis. The Company believes that it has provided adequate reserves for its income tax uncertainties in all open tax years. As the outcome of the audits cannot be predicted with certainty, if any issues addressed in the Company's tax audits are resolved in a manner inconsistent with management's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. There were no material changes in gross unrecognized tax benefits during each of the six months ended June 30, 2019 and 2018.
