	2. Summary of Significant Accounting Policies
	Basis of Presentation and Consolidation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on March 7, 2014 (“Prospectus”).
	The Company’s condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated. The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2014.
	There have been no changes to our significant accounting policies described in the Prospectus that have had a material impact on our condensed consolidated financial statements and related notes.
	Initial Public Offering
	In March 2014, the Company completed its initial public offering (“IPO”) in which it issued and sold 12,075,000 shares of common stock at a public offering price of $16.00 per share. The Company received net proceeds of $179.7 million after deducting underwriting discounts and commissions of $13.5 million, but before deducting offering expenses of $5.4 million. In addition, in connection with the IPO:
	—	All of the Company’s outstanding redeemable convertible preferred stock converted into 41,580,507 shares of common stock.
	—	The Company recognized stock-based compensation expense of $13.1 million during the three months ended March 31, 2014 associated with restricted stock units (“RSUs”). Please see Note 9 (Stock-based Compensation) for further discussion.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results may differ from the Company’s estimates, and such differences may be material to the accompanying condensed consolidated financial statements.

	Total	$	14,918	$	—	$	—	$	14,918
	Included in cash and cash equivalents							$	14,918
	Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
	Level 1—Quoted prices in active markets for identical assets or liabilities.
	Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3—Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.
	Valuation techniques used to measure the fair value of money market funds were derived from quoted prices in active markets for identical assets or liabilities.

	6. Acquisition of Yub, Inc.
	On January 2, 2014, the Company acquired all the outstanding shares of Yub, Inc. (“Yub”), a company that allows consumers to link digital offers and promotions to payment cards for savings when they use the cards for in-store purchases. The total acquisition consideration of $10.1 million, which consisted of 1,000,040 shares of the Company’s common stock, was based on the fair value of the Company’s common stock of $10.05 per share. The acquisition of YUB provides the Company with developed technologies and enhanced workforce. The fair values of identifiable intangible assets were determined using discounted cash flow models. The excess of the consideration paid over the fair values of the tangible and identifiable intangible assets acquired and liabilities assumed was recorded as goodwill, which is not deductible for tax purposes. The goodwill is attributable to expected synergies from combined operations and acquired company’s knowhow.
	The following table summarizes the consideration paid and the fair values of the assets acquired and liabilities assumed at the acquisition date (in thousands):
		Amount
	Cash	$	859
	Other assets and (liabilities), net		(1,100	)

	Acquisition related costs of $376,000 were expensed as general and administrative expense in the accompanying condensed consolidated statement of operations. The results of operations of Yub have been included in our condensed consolidated statements of operations from the acquisition date. The pro forma impact of this acquisition on consolidated revenues, loss from operations and net loss was immaterial.

Debt Obligations	'
	8. Debt Obligations
	2013 Credit and Security Agreement
	In September 2013, the Company entered into an agreement with a commercial bank to establish an accounts receivable based revolving line of credit. The maximum amount available for borrowing under the revolving credit facility is the lesser of $25,000,000 (which can be increased to $30,000,000 if certain conditions are met) or an amount equal to 85% of certain eligible accounts, which excludes accounts that are over 60 days outstanding from the original due date. The revolving line of credit has a maturity date of September 30, 2016 and may be repaid and redrawn at any time prior to the maturity date. Interest is charged at a floating interest rate based on the daily three month LIBOR, plus a 2.75% applicable margin. Interest was 3.0% at March 31, 2014. The Company is also required to pay a commitment fee on the unused portion of the revolving credit facility equal to 0.25% per annum. As of March 31, 2014 and December 31, 2013, $7,500,000 was outstanding under the revolving line of credit. The revolving credit facility is secured by substantially all of the Company’s assets, and is subject to certain financial and non-financial covenants, including financial reporting at certain specified intervals. As of March 31, 2014, the Company was in compliance with the financial and non-financial covenants under the credit and security agreement.
	2012 Note Payable, Related Party
	In October 2012, the Company borrowed $15,000,000 from one of its stockholders by entering into a subordinated note arrangement. The note is subordinated to other senior debt. The note has a stated interest rate of 4.00% per annum, and the principal and accrued interest are due in a lump-sum payment on October 5, 2014. Accrued interest related to the related party debt obligation is included in debt obligations, related party on the accompanying condensed consolidated balance sheets.
	In connection with the note, the Company issued a warrant to purchase 400,000 shares of Company’s common stock at an exercise price of $4.03 per share. In February 2014, the warrant to purchase 400,000 shares of common stock was exercised.

	2013 Equity Incentive Plan
	In October 2013, the Company adopted the 2013 Equity Incentive Plan (the “2013 Plan”), which became effective in March 2014 and serves as the successor to the Company’s 2006 Stock Plan (the “2006 Plan”). Pursuant to the 2013 Plan, 4,000,000 shares of common stock were initially reserved for grant, plus (1) any shares that were reserved and available for issuance under the 2006 Plan at the time the 2013 Plan became effective, and (2) any shares that become available upon forfeiture or repurchase by us under the 2006 Plan and 2000 Plan. Under the 2013 Plan, the Company may grant stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares and units to employees, directors and consultants.
	Stock Options
	The fair value of each stock option is estimated on the date of grant for the periods presented using the Black-Scholes model based on the following assumptions:
		Three Months Ended March  31,
		2014			2013
	Expected life (in years)		6.08			6.08
	Risk-free interest rate		2.33%			1.09%
	Volatility		55%			51%
	Dividend yield		—			—
	The weighted-average grant-date fair value of options granted was $8.60 and $1.80 per share during the three months ended March 31, 2014 and 2013, respectively.
	Restricted Stock Units
	The fair value of RSUs equals the market value of the Company’s common stock on the date of grant. The RSUs have a contractual term of seven years and vest upon the satisfaction of both a service condition and a liquidity-event condition. The service condition is satisfied as to 25% of the RSUs on each of the first four anniversaries of the vesting commencement date. The liquidity-event condition is satisfied upon the earlier of (i) six months after the effective date of the IPO or (ii) March 15 of the calendar year following the year in which the IPO was declared effective; and (iii) the time immediately prior to the consummation of a change in control. The vesting condition that will be satisfied six months following the Company’s IPO does not affect the expense attribution period for the RSUs for which the service condition has been met as of the date of the Company’s IPO. This six-month period is not a substantive service condition and, accordingly, beginning on the effectiveness of the Company’s IPO in March  2014, we recognized a cumulative stock-based compensation expense for the portion of the RSUs that had met the service condition as of the date of the Company’s IPO.
	A summary of the Company’s stock option and RSUs award activity under the Plan is as follows:

	Employee Stock Purchase Plan
	The Company’s Board of Directors adopted the 2014 Employee Stock Purchase Plan (“ESPP”), which became effective in March 2014, pursuant to which 1,200,000 shares of common stock have been reserved for future issuance. Eligible employees can enroll and elect to contribute up to 15% of their base compensation through payroll withholdings in each offering period, subject to certain limitations. Each offering period is six months in duration, with the exception of the initial offering period which commenced in March 2014 and ends in November 2014. The purchase price of the stock is the lower of 85% of the fair market value on (a) the first day of the offering period or (b) the purchase date.
	The fair value of the option feature is estimated using the Black-Scholes model for the period presented based on the following assumptions:

	Reverse Stock Split
	In February 2014, the Company’s board approved an amendment to the restated certificate of incorporation to effect a 2.5-for-1 reverse stock split of its capital stock. All share and per share information for all periods presented has been adjusted to reflect the effect of such reverse stock split.
	Amended and Restated Certificate of Incorporation
	In March 2014, the Company filed an amended and restated certificate of incorporation, which became effective immediately following the completion of the Company’s IPO. Under the restated certificate of incorporation, the authorized capital stock consists of 250,000,000 shares of common stock and 10,000,000 shares of preferred stock.
	Common Stock. The rights, preferences and privileges of the holders of common stock are subject to the rights of the holders of shares of any series of preferred stock which the Company may issue in the future. Subject to the foregoing, for as long as such stock is outstanding, the holders of common stock are entitled to receive ratably any dividends as may be declared by the board of directors out of funds legally available for dividends. Holders of common stock are entitled to one vote per share on any matter to be voted upon by stockholders. The amended and restated certificate of incorporation establishes a classified board of directors that is divided into three classes with staggered three year terms. Only the directors in one class will be subject to election at each annual meeting of stockholders, with the directors in other classes continuing for the remainder of their three year terms. Upon liquidation, dissolution or winding-up, the assets legally available for distribution to the Company’s stockholders would be distributable ratably among the holders of common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock.
	Preferred Stock. The board of directors is authorized to issue undesignated preferred stock in one or more series without stockholder approval and to determine for each such series of preferred stock the voting powers, designations, preferences, and special rights, qualifications, limitations, or restrictions as permitted by law, in each case without further vote of action by the stockholders. The board of directors can also increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding, without any further vote or action by the stockholders. The board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of common stock.
	Amendment. The amendment of the provisions in the restated certificate requires approval by holders of at least 66 2/3% of the Company’s outstanding capital stock entitled to vote generally in the election of directors.

The benefit from income taxes during the first quarter of 2014 is due to acquired net deferred tax liabilities as part of the Yub acquisition.  These additional deferred tax liabilities create a new source of taxable income, which requires the release of a portion of the Company’s deferred tax asset valuation allowance with a related reduction in income tax expense.

	Litigation
	In the ordinary course of business, the Company may be involved in lawsuits, claims, investigations, and proceedings consisting of intellectual property, commercial, employment, and other matters. The Company will record a provision for these claims when it is both probable that a liability has been incurred and the amount of the loss, or a range of the potential loss, can be reasonably estimated. These provisions are reviewed regularly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information or events pertaining to a particular case. In the event that one or more of these matters were to result in a claim against the Company, an adverse outcome, including a judgment or settlement, may cause a material adverse effect on the Company’s future business, operating results, or financial condition.
	The Company believes that liabilities associated with any claims are not probable and any reasonably possible range of losses cannot be estimated at this time, therefore the Company has not recorded any accrual for claims as of March 31, 2014 and December 31, 2013.
