Basis of Presentation and Summary of Significant Accounting Policies
Reverse Stock Split	Reverse Stock Split On September 2, 2016, the Company effected a 1-for-3 reverse stock split of its outstanding common stock and a proportional adjustment to the then existing conversion ratios for each series of convertible preferred stock. Accordingly, all share and per share amounts for all periods presented in these condensed consolidated financial statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split and adjustment of the preferred stock conversion ratios.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from these estimates under different assumptions or circumstances.
Fair Value of Financial Instruments	Fair Value of 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. Fair value measurements are based on a fair value hierarchy, based on three levels of inputs, of which the first two are considered observable and the last unobservable, which are the following: Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted market prices for similar assets and 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 asset or liability. Level 3—Unobservable inputs. Observable inputs are based on market data obtained from independent sources. The carrying amounts of accounts receivable, accounts payable, accrued expenses and other current liabilities approximate fair value due to the short-term nature of these instruments. The carrying value of the line of credit and term loans approximates fair value based on borrowing rates currently available to the Company for financing with similar terms and were determined to be Level 2. The Company’s convertible preferred stock warrants were measured using unobservable inputs that required a high level of judgment to determine fair value, and were thus classified as Level 3. Immediately prior to the closing of the Company’s IPO, all of the Company’s then-outstanding convertible preferred stock warrants were remeasured and automatically converted and reclassified into Class B common stock warrants and all remaining warrants were net exercised. Certain long-lived assets, including property and equipment and capitalized software development costs, are also subject to measurement at fair value on a non-recurring basis if they are deemed to be impaired as a result of an impairment review. To date, no impairments have been recorded on those assets.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Under the Jumpstart Our Business Startups Act (“JOBS Act”), the Company meets the definition of an emerging growth company. The Company has irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards for revenue recognition. Under ASU 2014-09, a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. Additionally, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU No. 2015-14, which defers the effective date of ASU 2014-09 by one year. During 2016, the FASB has continued to issue additional amendments to the new revenue guidance. The new revenue guidance is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017. Early adoption is permitted for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016. The guidance permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method nor determined the effect of this guidance on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, which provides guidance to help companies evaluate the accounting for fees paid by a customer in a cloud computing arrangement. Under ASU 2015-05, if a cloud computing arrangement includes a software license, the customer should account for the license consistent with its accounting for other software licenses. If the arrangement does not include a software license, the customer should account for the arrangement as a service contract. ASU 2015-05 was effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. An entity can elect to adopt this guidance either prospectively for all arrangements entered into or materially modified after the effective date, or retrospectively. Early adoption was permitted. The Company’s adoption of this guidance during the three months ended March 31, 2016 did not have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires an entity to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, lessor, and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the income statement. The guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those reporting periods, and requires a modified retrospective adoption, with early adoption permitted. The Company is evaluating the impact of this guidance on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which includes multiple provisions intended to simplify various aspects of the accounting for share-based payments, including forfeitures, accounting for income taxes, classification of excess tax benefits on the statement of cash flows, statutory tax withholding requirements and other stock based compensation classification matters. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted in any interim or annual period with the impact of the adoption recorded as a cumulative-effect adjustment as of the beginning of the year in which the guidance is adopted. Changes in the classification of excess tax benefits on the statement of cash flows as a result of the adoption of this guidance may be recorded on a retrospective or prospective basis. The Company elected to early adopt this guidance during the three months ended June 30, 2016 and changed its accounting policy to record forfeitures of stock-based awards when they occur. The Company’s adoption of this guidance did not have a material impact on its consolidated financial statements. The Company had no excess tax benefits as of December 31, 2015 and elected to record any future excess tax benefits in the statement of cash flows as an operating activity on a prospective basis. The cumulative-effect adjustment as a result of the adoption of this guidance for the change in accounting policy for forfeitures was approximately $5,000 and was recorded in the statement of operations during the three months ended June 30, 2016, rather than an adjustment to the retained earnings as the amount was not material. The change in accounting policy to record forfeitures when they occur and the requirement to record excess tax benefits when they occur in the statement of operations will result in increased volatility in earnings in the future. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If adopted in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes such interim period. The adoption of ASU 2016-15 should be applied using a retrospective transition method to each period presented, unless impracticable to do so. The Company does not expect the adoption of ASU 2016-15 will have a material impact on its consolidated statement of cash flows.

Basis of Presentation and Summary of Significant Accounting Policies

On September 2, 2016, the Company effected a 1-for-3 reverse stock split of its outstanding common stock and a proportional adjustment to the then existing conversion ratios for each series of convertible preferred stock. Accordingly, all share and per share amounts for all periods presented in these condensed consolidated financial statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split and adjustment of the preferred stock conversion ratios.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from these estimates under different assumptions or circumstances.

Fair Value of 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. Fair value measurements are based on a fair value hierarchy, based on three levels of inputs, of which the first two are considered observable and the last unobservable, which are the following:

Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted market prices for similar assets and 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 asset or liability.

Level 3—Unobservable inputs.

Observable inputs are based on market data obtained from independent sources.

The carrying amounts of accounts receivable, accounts payable, accrued expenses and other current liabilities approximate fair value due to the short-term nature of these instruments. The carrying value of the line of credit and term loans approximates fair value based on borrowing rates currently available to the Company for financing with similar terms and were determined to be Level 2.

The Company’s convertible preferred stock warrants were measured using unobservable inputs that required a high level of judgment to determine fair value, and were thus classified as Level 3. Immediately prior to the closing of the Company’s IPO, all of the Company’s then-outstanding convertible preferred stock warrants were remeasured and automatically converted and reclassified into Class B common stock warrants and all remaining warrants were net exercised.

Certain long-lived assets, including property and equipment and capitalized software development costs, are also subject to measurement at fair value on a non-recurring basis if they are deemed to be impaired as a result of an impairment review. To date, no impairments have been recorded on those assets.
