Organization Consolidation And Presentation Of Financial Statements Abstract | |
Nature of the Business and Basis of Presentation | 1. Nature of the Business and Basis of Presentation EverQuote, Inc. (the “Company”) was incorporated in the state of Delaware in 2008. Through its internet websites, the Company operates an online marketplace for consumers shopping for auto, home and life insurance quotes. The Company generates revenue by selling consumer referrals to insurance provider customers, consisting of carriers and agents, and indirect distributors in the United States. The Company is subject to a number of risks and uncertainties common to companies in similar industries and stages of development including, but not limited to, rapid technological changes, competition from substitute products and services from larger companies, protection of proprietary technology, customer concentration, patent litigation, the need to obtain additional financing to support growth and dependence on third parties and key individuals. On July 2, 2018, the Company completed an initial public offering (“IPO”), in which it issued and sold 3,125,000 shares of Class A common stock at a public offering price of $18.00 per share, resulting in net proceeds to the Company of approximately $48.6 million after deducting underwriting discounts and commissions and other offering costs. Additionally, certain of the Company’s stockholders sold 1,562,500 shares of Class A common stock at the same public offering price of $18.00 per share. The Company did not receive any proceeds from the sale of shares by its stockholders. Upon closing of the IPO, the Company’s outstanding redeemable convertible preferred stock automatically converted into shares of Class B common stock (see Note 5). The accompanying condensed financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. Since inception, the Company has incurred operating losses, including net losses of $6.9 million for the nine months ended September 30, 2018 and $5.1 million for the year ended December 31, 2017. As of September 30, 2018, the Company had an accumulated deficit of $93.0 million. The Company has primarily funded its operations through issuances of shares of redeemable convertible preferred stock and common stock, debt, including a revolving line of credit with Western Alliance Bank, cash flows from operations and proceeds from the Company’s IPO. As of November 14, 2018, the issuance date of the interim financial statements, the Company expects that its cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next 12 months from the issuance date of the interim financial statements, without considering available borrowings under the Company’s revolving line of credit. The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and may remain an emerging growth company until the last day of the fiscal year following the fifth anniversary of the IPO, subject to specified conditions. The JOBS Act provides that an emerging growth company can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company has elected not to “opt out” of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company will adopt the new or revised standard at the time private companies adopt the new or revised standard, provided that the Company continues to be an emerging growth company. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Unaudited Interim Financial Information The balance sheet at December 31, 2017 was derived from audited financial statements but does not include all disclosures required by GAAP. The accompanying unaudited financial statements as of September 30, 2018 and for the three and nine months ended September 30, 2018 and 2017 have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto for the year ended December 31, 2017 included in the Company’s Registration Statement on Form S-1, File No. 333-225379 on Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, revenue recognition, the expensing and capitalization of website and software development costs, the valuation of common and preferred stock prior to the IPO, the valuation of stock-based awards and income taxes. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates, as there are changes in circumstances, facts and experience. Changes in estimates are recorded in periods in which they become known. Actual results may differ from those estimates or assumptions. Concentrations of Credit Risk and of Significant Customers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents at two accredited financial institutions. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. The Company sells its consumer referrals to insurance provider customers, consisting of carriers and agents, and indirect distributors in the United States. For the three months ended September 30, 2018 and 2017, one customer represented 22% and 19%, respectively, of total revenue. For the nine months ended September 30, 2018 and 2017, one customer represented 20% and 21%, respectively, of total revenue. As of September 30, 2018, two customers accounted for 28% and 13% of the accounts receivable balance. As of December 31, 2017, four customers accounted for 12%, 11%, 11% and 11% of the accounts receivable balance. Fair Value Measurements 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. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The Company’s cash equivalents of $22.5 million as of September 30, 2018, consisting of money market funds, are carried at fair value based on Level 1 inputs. The carrying values of the Company’s accounts receivable, accounts payable and accrued expenses and other current liabilities approximate their fair values due to the short-term nature of these assets and liabilities. Revenue Recognition The Company derives its revenue by selling consumer referrals to its insurance provider customers, including insurance carriers and agents. The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition Amounts received prior to satisfying the revenue recognition criteria listed above are recorded as deferred revenue in the accompanying balance sheets. Amounts expected to be recognized as revenue within 12 months of the balance sheet date are classified as current deferred revenue. Advertising Expense Advertising expense consists of variable costs that are related to attracting consumers to the Company’s marketplace, increasing downloads of its social safe-driving mobile app, EverDrive, and promoting its marketplace to insurance carriers and agents. The Company expenses advertising costs as incurred and such costs are included in sales and marketing expense in the accompanying statements of operations and comprehensive loss. For the three months ended September 30, 2018 and 2017, advertising expense totaled $29.2 million and $23.0 million, respectively. For the nine months ended September 30, 2018 and 2017, advertising expense totaled $87.7 million and $67.6 million, respectively. Accounts Receivable The Company provides credit to customers in the ordinary course of business and believes its credit policies are prudent and reflect industry practices and business risk. Management reviews accounts receivable on a periodic basis and reserves for receivables in the Company’s allowance for doubtful accounts on a specific identification basis when they are determined to be uncollectible. After the Company has exhausted all collection efforts, the outstanding receivable is written off against the allowance. The Company had no allowance for doubtful accounts as of September 30, 2018 and December 31, 2017, as amounts were deemed to be collectible.

Loan and Security Agreement | 4. Loan and Security Agreement As of December 31, 2017, the Company had outstanding borrowings under an amended Loan and Security Agreement including borrowings under a revolving line of credit and a term loan. The interest rate for the revolving line of credit was 5.0% as of December 31, 2017. The term loan was repayable in 36 equal monthly installments through August 2019 and accrued interest at an annual rate of 2.0% above the greater of 3.5% or the prime rate. The interest rate for the term loan was 6.5% as of December 31, 2017. Borrowings under the amended Loan and Security Agreement were collateralized by substantially all of the Company’s assets and property. In March 2018, the Company executed the 2018 Loan Modification (the “2018 Loan Modification”) to modify the amended Loan and Security Agreement to increase the revolving line of credit from $6.0 million to $11.0 million, extend the maturity date of the revolving line of credit to March 2020 and eliminate the term loan. Pursuant to the 2018 Loan Modification, borrowings under the revolving line of credit cannot exceed 80% of eligible accounts receivable balances and continue to bear interest at one-half Under the 2018 Loan Modification, the Company is subject to specified affirmative and negative covenants until maturity. These covenants include limitations on the Company’s ability to incur additional indebtedness and engage in certain fundamental business transactions, such as mergers or acquisitions. In addition, pursuant to the 2018 Loan Modification, the Company is required to maintain a financial performance covenant: a minimum asset coverage ratio of 1.5 to 1, calculated as the sum of unrestricted cash and qualified accounts receivable divided by borrowings outstanding under the revolving line of credit. Events which would meet the criteria of a default under the 2018 Loan Modification include failure to make payments when due, insolvency events, failure to comply with covenants or material adverse events with respect to the Company. As of September 30, 2018, the Company was in compliance with all covenants related to the revolving line of credit. There can be no guarantee that these covenants will be met in the future, and if not met, that waivers will be obtained. As of September 30, 2018, the Company had no amounts outstanding on the revolving line of credit. As of September 30, 2018, $11.0 million was available for borrowing under the revolving line of credit. |

Each share of Class B common stock entitles the holder to ten votes for each share on all matters submitted to a vote of the Company’s stockholders at all meetings of stockholders and written actions in lieu of meetings.

Stock-Based Compensation 2008 Stock Incentive Plan The Company’s 2008 Stock Incentive Plan, as amended (the “2008 Plan”), provided for the Company to issue equity awards to employees, consultants, advisors and directors. Under the 2008 Plan, the Company could grant stock-based incentive awards, including incentive or nonqualified stock options and restricted stock units, as determined by the board of directors. The total number of shares of common stock that could have been issued under the 2008 Plan was 8,440,712 shares. Upon effectiveness of the Company’s 2018 Equity Incentive Plan, (the “2018 Plan” and, together with the 2008 Plan, the “Plans”) on June 27, 2018, the remaining 583,056 shares that were available for grant under the 2008 Plan became available for grant under the 2018 Plan and no future grants will be made under the 2008 Plan. Additionally, shares underlying awards under the 2008 Plan that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right (subject, in the case of incentive stock options, to any limitations of the Internal Revenue Code) will be available for future grants under the 2018 Plan. Shares of common stock issued upon exercise of stock options granted prior to September 8, 2017 will be issued as Class B common stock. Shares of common stock issued upon exercise of stock options granted after September 8, 2017 will be issued as Class A common stock. 2018 Equity Incentive Plan On June 14, 2018, the Company’s board of directors adopted and its stockholders approved the 2018 Plan, which became effective on June 27, 2018. The 2018 Plan provides for the grant of incentive stock options, non-qualified Options and restricted stock granted under the Plans vest over periods determined by the board of directors. Options granted under the Plans expire ten years from the date of the grant. The exercise price for stock options granted is not less than the fair value of common shares as determined by the board of directors as of the date of grant. Prior to the Company’s IPO, the Company’s board of directors valued the Company’s common stock, taking into consideration its most recently available valuation of common stock performed by third parties as well as additional factors which may have changed since the date of the most recent contemporaneous valuation through the date of grant. Award Issuances During the nine months ended September 30, 2018, the Company granted options to employees and directors for the purchase of 1,342,840 shares of Class A common stock with a weighted average exercise price of $10.40 per share and a weighted average grant-date fair value of $5.09 per share. During the nine months ended September 30, 2018, the Company granted service- and performance-based RSUs to employees and directors for the right to receive 2,103,272 shares of Class A common stock with a weighted average grant date fair value of $17.27 per share.

Income Taxes | 8. Income Taxes 2017 U.S. Tax Reform On December 22, 2017, tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “TCJA”) was signed into United States law. The TCJA includes a number of changes to existing tax law, including, among other things, a permanent reduction in the federal corporate income tax rate from 35% to 21%, effective as of January 1, 2018, as well as a limitation of the deduction for net operating losses to 80% of current year taxable income and the elimination of net operating loss carrybacks, in each case, for losses arising in taxable years beginning after December 31, 2017 (though any such net operating losses may be carried forward indefinitely). The federal tax rate change resulted in a reduction of the Company’s deferred tax assets and liabilities, and a corresponding reduction to its valuation allowance. As a result, no income tax expense or benefit was recognized as of the enactment date of the TCJA. The other provisions of the TCJA did not have a material impact on the Company’s financial statements. Income Taxes The Company had no income tax expense for the three or nine months ended September 30, 2018 and 2017. The Company has no foreign operations and therefore, has not provided for any foreign taxes. |

Earnings Per Share [Abstract] | |
Net Loss per Share | 10. Net Loss per Share The Company has two classes of common stock. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. As a result, basic and diluted net loss per share of Class A common stock and share of Class B common stock are equivalent. Basic and diluted net loss per share attributable to common stockholders was calculated as follows (in thousands, except share and per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Numerator: Net loss $ (3,808 ) $ (1,135 ) $ (6,866 ) $ (4,418 ) Accretion of redeemable convertible preferred stock to redemption value — 531 (37,415 ) (12,248 ) Net loss attributable to common stockholders $ (3,808 ) $ (604 ) $ (44,281 ) $ (16,666 ) Denominator: Weighted average common shares outstanding, basic and diluted 24,595,102 8,622,072 14,187,261 8,800,461 Net loss per share attributable to common stockholders, basic and diluted $ (0.15 ) $ (0.07 ) $ (3.12 ) $ (1.89 ) The Company’s potentially dilutive securities have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share attributable to common stockholders. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the three and nine months ended September 30, 2018 and 2017 because including them would have had an anti-dilutive effect: September 30, 2018 2017 Redeemable convertible preferred stock (as converted to common stock) — 12,596,064 Options to purchase common stock 3,908,922 3,452,920 Unvested restricted stock units 2,280,993 264,000 6,189,915 16,312,984 |

Fair Value Measurements | Fair Value Measurements 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. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The Company’s cash equivalents of $22.5 million as of September 30, 2018, consisting of money market funds, are carried at fair value based on Level 1 inputs. The carrying values of the Company’s accounts receivable, accounts payable and accrued expenses and other current liabilities approximate their fair values due to the short-term nature of these assets and liabilities. |
