Summary of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	Accounting Principles
	The consolidated financial statements and accompanying notes were prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”).
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates include depreciable lives for property and equipment, stock-based compensation, income taxes, accrued liabilities and collectability of accounts receivable. Actual results could differ from those estimates.
	Foreign Currency
	The financial statements of our foreign subsidiaries with a functional currency other than U.S. dollars have been translated into U.S. dollars. Assets and liabilities of these subsidiaries are translated at the exchange rate in effect at each period-end. Income statement amounts are translated at the average rate of exchange prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included in other comprehensive income (loss). Gains and losses on foreign currency transactions are included in income. Losses attributable to foreign currency transactions were $0.9 million for the year ended December 31, 2013 and were not significant during the years ended December 31, 2012 and 2011.
	Initial Public Offering
	On May 22, 2013, we completed our initial public offering ("IPO") whereby 9,430,000 shares of Class A common stock were sold to the public at a price of $31.00 per share. We sold 6,230,000 shares of Class A common stock and the selling stockholders sold 3,200,000 shares of Class A common stock. We received aggregate proceeds of $177.0 million from the IPO, net of underwriters’ discounts and commissions, and offering expenses. Upon the closing of the IPO, all shares of our outstanding convertible preferred stock automatically converted into shares of Class B common stock.
	Segments
	We follow the authoritative literature that established annual and interim reporting standards for enterprise’s operating segments and related disclosures about its products and services, geographic regions and major customers.
	We operate our business as one operating segment. Our chief operating decision makers (“CODM”) are our Chief Executive Officer and Chief Financial Officer, who review financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.
	Revenue Recognition
	We generate revenues primarily in the form of software license fees and related maintenance and services fees. License fees include perpetual, term and subscription license fees. Maintenance and services fees primarily consist of fees for maintenance services (including support and unspecified upgrades and enhancements when and if they are available), training, and professional services that are not essential to functionality of the software.
	We recognize revenues when all of the following conditions are met:
	•	there is persuasive evidence of an arrangement;
	•	the software or services have been delivered to the customer;
	•	the amount of fees to be paid by the customer is fixed or determinable; and
	•	the collection of the related fees is probable.
	We use click-through license agreements, signed agreements and purchase orders as evidence of an arrangement. We deliver all of our software electronically. Electronic delivery occurs when we provide the customer with access to the software and license key via a secure portal. We assess whether the fee is fixed or determinable at the outset of the arrangement. Our typical terms of payment are due 30 days from delivery. We assess collectability based on a number of factors such as collection history and creditworthiness of the customer. If we determine that collectability is not probable, revenue is deferred until collectability becomes probable, generally upon receipt of cash.
	Substantially all of our software licenses are sold in multiple-element arrangements that include maintenance and may include professional services and training.
	Vendor specific objective evidence (“VSOE”) of the fair value is not available for software licenses as they are never sold without maintenance. VSOE of the fair value generally exists for all undelivered elements and any services that are not essential to the functionality of the delivered software. We account for delivered software licenses under the residual method.
	Maintenance agreements consist of fees for providing software updates on a when and if available basis and technical support for software products (“post-contract support” or “PCS”) for an initial term, generally one year. We have established VSOE of the fair value for maintenance on perpetual licenses based on stated substantive renewal rates or the price when sold on a standalone basis. Stated renewal rates are considered to be substantive if they are at least 15% of the actual price charged for the software license. VSOE of the fair value for standalone sales is considered to have been established when a substantial majority of individual sales transactions within the previous 12 months period fall within a reasonably narrow range, which we have defined to be plus or minus 15% of the median sales price of actual standalone sales transactions.
	License arrangements may include professional services and training. In determining whether professional services and training revenues should be accounted for separately from license revenues, we evaluate whether such services are considered essential to the functionality of the software using factors such as the nature of the software products; whether they are ready for use by the customer upon receipt; the nature of the services, which typically do not involve significant customization to or development of the underlying software code; the availability of services from other vendors; whether the timing of payments for license revenues coincides with performance of services; and whether milestones or acceptance criteria exist that affect the realizability of the software license fee. Revenues related to training are billed on a fixed fee basis and accordingly recognized as training services are delivered. Payments received in advance of services performed are deferred and recognized when the related services are performed.
	To date, professional services have not been considered essential to the functionality of the software. The VSOE of fair value of our professional services and training is based on the price for these same services when they are sold separately. Revenues related to professional services are billed on a time and materials basis and, accordingly, are recognized as the services or training are performed.
	When software is licensed for a specified term or on a subscription basis, fees for support and maintenance are generally bundled with the license fee over the entire term of the contract. In these cases, we do not have VSOE of the fair value for support and maintenance. Revenues related to term license fees are recognized ratably over the contract term beginning on the date the customer has access to the software license key and continuing through the end of the contract term.
	We do not offer refunds and therefore have not recorded any sales return allowance for any of the periods presented. Upon a periodic review of outstanding accounts receivable, amounts that are deemed to be uncollectable are written off against the allowance for doubtful accounts.
	We account for taxes collected from customers and remitted to governmental authorities on a net basis and exclude them from revenues.
	Risks and Uncertainties
	Inherent in our business are various risks and uncertainties, including our limited operating history and development of advanced technologies in a rapidly changing industry. These risks include our ability to manage our rapid growth and our ability to attract new customers and expand sales to existing customers, as well as other risks and uncertainties. In the event that we do not successfully implement our business plan, certain assets may not be recoverable, certain liabilities may not be paid and investments in our capital stock may not be recoverable. Our success depends upon the acceptance of our technology, development of sales and distribution channels, and our ability to generate significant revenues from the use of its technology.
	Cash and Cash Equivalents
	We consider all highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value. We maintain cash and cash equivalent balances which exceed the insured limits by the Federal Deposit Insurance Corporation.
	Accounts Receivable
	Accounts receivable consist of amounts billed currently due from customers. Our accounts receivable are subject to collection risk. Our gross accounts receivable is reduced for this risk by a provision for doubtful accounts. This provision is for estimated losses resulting from the inability of our customers to make required payments. It is an estimate and is regularly evaluated for adequacy by taking into consideration a combination of factors. We look at factors such as past collection experience, credit quality of the customer, age of the receivable balance, and current economic conditions. These factors are reviewed to determine whether a provision for doubtful accounts should be recorded to reduce the receivable balance to the amount believed to be collectible.
	Activity related to our provision for doubtful accounts was as follows:

	Accounts written off	(291		)	(149		)	(19		)
	Balance at the end of the period	$	805		$	307		$	135
	Property and Equipment
	Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets generally ranging from three to seven years. Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in the consolidated statements of operations. Maintenance and repairs that do not improve or extend the lives of the respective assets are charged to expense in the period incurred.
	Impairment of Long-Lived Assets
	We evaluate the recoverability of long-lived assets in accordance with authoritative guidance on accounting for the impairment or disposal of long-lived assets. We evaluate long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. Such impairment is recognized in the event the carrying value of such assets exceeds their fair value. If the carrying value of the net assets assigned exceeds the fair value of the assets, then the second step of the impairment test is performed in order to determine the implied fair value. No impairment of long-lived assets occurred in the periods presented.
	Fair Value
	We establish fair value of our assets and liabilities using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and using a fair value hierarchy based on the inputs used to measure fair value. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash equivalents, accounts receivable, accounts payable, and accrued and other current liabilities, due to their short-term nature.
	Software Development Costs
	Software development costs associated with the development of new products, enhancements of existing products and quality assurance activities consists of employee, consulting and other external personnel costs. The costs incurred internally from the research and development of computer software products are charged to expense until technological feasibility has been established for the product. Once technological feasibility is established, all software costs are capitalized until the product is available for release to customers. Judgment is required in determining when technological feasibility of a product is established. To date, we have determined that technological feasibility of software products is reached shortly before the products are released. Costs incurred after establishment of technological feasibility have not been material, and therefore, we have expensed all research and development costs as they were incurred. Research and development expenses primarily consist of
	personnel related costs attributable to our research and development personnel and allocated overhead.
	We capitalize certain costs relating to software acquired, developed, or modified solely to meet our internal requirements and for which there are no substantive plans to market the software. To date, we have not capitalized any such costs.
	Intangible Asset Costs
	Costs related to filing and pursuing patent and trademark applications are expensed as incurred, as recoverability of such expenditures is uncertain. These intangible asset-related legal costs are reported as a component of general and administrative expenses.
	Advertising Expenses
	We have expensed all advertising costs as incurred and classify these costs as sales and marketing expenses. Advertising expenses for the years ended December 31, 2013, 2012 and 2011 were $4.9 million, $3.0 million, and $1.7 million, respectively.
	Deferred Offering Costs
	Deferred offering costs, consisting of legal, accounting and other fees and costs relating to the IPO, were capitalized and included in deposits and other noncurrent assets in the consolidated balance sheets. The deferred offering costs were offset against our IPO proceeds upon the closing of our IPO. There were $0.3 million of capitalized deferred offering costs as of December 31, 2012, and no similar costs as of December 31, 2013.
	Income Taxes
	Our deferred tax assets are determined based on temporary differences between the financial reporting and income tax basis of assets and liabilities and are measured using the tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that the deferred tax assets will not be realized.
	We determine whether our uncertain tax positions are more likely than not to be sustained upon examination based on the technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the consolidated financial statements is reduced by the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority.
Concentrations of Credit Risk
Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We extend credit to customers based upon an evaluation of the customer’s financial condition and generally collateral is not required. As of December 31, 2013, no individual customer accounted for 10% or more of total accounts receivable. As of December 31, 2012, one customer accounted for 10% or more of total accounts receivable. For the years ended December 31, 2013, 2012 and 2011, no individual customer represented 10% or more of our total revenues.
Stock-Based Compensation
Compensation expense related to stock-based transactions, including employee and non-employee director stock option and restricted stock unit (“RSU”) awards, is measured and recognized in the financial statements based on fair value. The fair value of each RSU award is based on the number of shares subject to the RSU grant and the closing price of our Class A common stock as reported on the New York Stock Exchange on the date of grant.
The fair value of each stock option award is determined at the date of grant by applying the Black-Scholes option pricing model. This model utilizes the estimated value of our underlying Class A common stock and Class B common stock (together, “common stock”) at the measurement date, the expected or contractual term of the option, the expected volatility of our common stock, risk-free interest rates and expected dividend yield of our common stock. Prior to our initial public offering in May 2013, because our stock was not publicly traded we estimated the fair value of our common stock. Our board of directors considered numerous objective and subjective factors to determine the fair value of our common stock at each meeting at which awards were approved. The factors included, but were not limited to: (i) contemporaneous third-party valuations of our common stock; (ii) the prices, rights, preferences and privileges of our preferred stock that was then outstanding relative to those of our common stock; (iii) the lack of marketability of our common stock; (iv) our actual operating and financial results; (v) current business conditions and projections; and (vi) the likelihood of achieving a liquidity event, such as an initial public offering or merger or acquisition, given prevailing market conditions. After the completion of our initial public offering, our common stock has been valued by reference to the closing price of our Class A common stock on the New York Stock Exchange.
Measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instruments vest. We recognize compensation expense for only the portion of awards expected to vest. Therefore, management applied an estimated forfeiture rate that was derived from historical employee termination behavior. If the actual number of forfeitures differs from the estimates, adjustments to stock-based compensation expense may be required in future periods.
We have elected to compute the timing of excess tax benefits from the exercise of stock options and the vesting and settlement of RSUs under the “with-and-without” approach. Under this approach, we will not record an excess tax benefit until such time as a cash tax benefit is recognized. We include the impact of the excess tax benefits in the calculation of certain tax attributes such as the research and development ('R&D") tax credit and do not prepare separate computations considering the cascading impacts of the excess tax deduction. We compute the pool of excess tax benefits available to offset any future shortfalls in the tax benefits actually realized as a single pool for employees and non-employees.
Fair Value Measurements
We categorize assets and liabilities recorded at fair value on our consolidated balance sheets based upon the level of judgment associated with inputs used to measure their fair value. The levels of the fair value hierarchy are as follows:
•	Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
•	Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or quoted prices
for identical or similar instruments in markets that are not active and model-derived valuations in
which all significant inputs and significant value drivers are observable in active markets.
•	Level 3—Inputs are unobservable inputs based on our own assumptions and valuation
techniques used to measure assets and liabilities at fair value. The inputs require significant
management judgment or estimation.
Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.
Recent Accounting Pronouncements
In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists, or ASU 2013-11. ASU 2013-11 requires entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when settlement in this manner is available under the tax law. ASU 2013-11 is effective for public calendar year end companies for the first quarter of 2014, and applied prospective with early adoption permitted.  As of December 31, 2013, we have elected early adoption and have presented $3.4 million of unrecognized tax benefit as a reduction to deferred income tax assets in our consolidated balance sheet.
As an “emerging growth company”, the Jumpstart Our Business Startups Act allows us to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies.

	The effective tax rate in 2013 is (147.0)% compared to 66.1% in 2012. The decrease was due to the increase of the research and development ("R&D") tax credit generated in 2013 of $6.8 million and the 2012 amount recorded in 2013 due to the retroactive enactment of the federal tax credit under the 2012 Taxpayer Relief Act of $1.0 million. The impact of the increase of the R&D tax credit was partially offset by an increase to non-deductible stock-based compensation expense of $0.6 million and meals and entertainment expense of $0.4 million, as well as an unfavorable foreign tax rate differential.

	Prepaid assets		1,484				715
	Total deferred income tax liabilities		2,398				2,840
	Net deferred income tax assets		$	9,725			$	959
	The above schedule includes short-term and long-term deferred income tax assets and liabilities. In our consolidated balance sheet, we presented all current deferred income tax assets and liabilities within the same tax jurisdiction as a single amount. Long-term deferred income tax assets and liabilities are presented using the same methodology.
	We determine our deferred income tax assets and liabilities based on differences between the financial reporting and tax basis of assets and liabilities using the enacted tax rates and laws that will be in effect when we expect the differences to reverse. In addition, we record deferred tax assets for net operating loss ("NOL")carryforwards and tax credit carryovers. A valuation allowance is recorded when it is more likely than not that all or some portion of the deferred tax asset will not be realized. Prior to 2011, we provided a valuation allowance against our U.S. federal and state net deferred tax assets, however, in the quarter ended December 31, 2011, we concluded that it was more likely than not that the deferred income tax assets would be realized and released our entire valuation allowance of $1.0 million. Currently, we believe that it is more likely than not that the Company will realize its current and long-term deferred tax assets as a result of future taxable income. Significant factors we considered in determining the probability of the realization of the deferred income tax assets include expected future earnings, the Company’s historical operating results and the reversal of deferred income tax liabilities. Accordingly, no valuation allowance has been recorded on the deferred income tax assets. If we were to determine we are not able to realize all or part of our net deferred income tax assets in the future, we would record a valuation allowance on such net deferred income tax assets with a corresponding increase in expense in the period such determination was made.
	NOL carryforwards created by excess tax benefits from the exercise of stock options are not recorded as deferred income tax assets. To the extent such NOL carryforwards are utilized, we will increase stockholders' equity. At December 31, 2013, for income tax return purposes we have gross federal and state NOL carryforwards totaling $201.9 million and R&D tax credit carryforwards totaling $12.8 million. These carryforwards may be subject to limitations under the Internal Revenue Code and applicable state tax law. If not utilized, a portion of the carryfowards will begin to expire in 2024.
Of the excess stock based compensation NOLs generated in 2013, the Company plans to carry back deductions of $10.4 million for U.S. federal income tax purposes to the 2012 tax year. This carry back should result in a federal tax refund of $1.9 million.
We are subject to income taxes in the U.S. and in numerous foreign jurisdictions. The statute of limitations for adjustments to our historic tax obligations will vary from jurisdiction to jurisdiction. Furthermore, net operating loss and tax credit carryforwards may be subject to adjustment after the expiration of the statute of limitations of the year such net operating losses and tax credits originated. In general, the tax years for U.S. federal and state income tax purposes, that remain open for examination are for 2005 and forward due to its operating loss carryforwards.
Income tax expense includes U.S. and international income taxes. Except as required under U.S. tax law, we do not provide for U.S. income taxes on our undistributed earnings of foreign subsidiaries that have not been previously taxed, because we intend to invest such undistributed earnings indefinitely outside of the U.S. Undistributed earnings of foreign subsidiaries that are indefinitely invested outside the U.S. were approximately $0.6 million at December 31, 2013. Determination of the unrecognized deferred tax liability that would be incurred if such amounts were repatriated is not practicable.
We have reserves for taxes to address potential exposures involving tax positions that we believe could be challenged by taxing authorities even though we believe the positions we have taken are appropriate. We believe our tax reserves are adequate to cover potential liabilities. We review the tax reserves as circumstances warrant and adjust the reserves as events occur that affect our potential liability for additional taxes. It is often difficult to predict the final outcome or timing of resolution of any particular tax matter. Various events, some of which cannot be predicted, such as clarification of tax law by administrative or judicial means, may occur and would require us to increase or decrease our reserves and effective income tax rate.
The total gross amount of unrecognized tax benefits was $3.4 million, $0.4 million, and $0.4 million as of December 31, 2013, 2012 and 2011, respectively. These amounts represent the gross amount of exposure in individual jurisdictions and do not reflect any additional benefits expected to be realized if such positions were not sustained. To the extent that any uncertain tax positions are resolved in our favor, it may have a positive impact on our effective income tax rate. We do not expect any material decrease on our unrecognized tax position within the next twelve months. The table below shows the gross changes in our unrecognized tax position.

	All of our convertible preferred stock automatically converted into shares of Class B common stock upon the closing of our IPO in May 2013. As of December 31, 2013, we have no preferred stock outstanding. Significant terms of Series A and B convertible preferred stock prior to our IPO were as follows:
	Voting
	Each holder of preferred stock was entitled to vote on all matters and was entitled to that number of votes equal to the number of votes that would be accorded to the number of shares of Class B common stock into which such holder’s preferred stock could be converted.
	Dividends
	The holders of preferred stock were entitled to receive noncumulative dividends prior to and in preference to any dividends to common stockholders, at a rate of $0.1374 and $0.0282 per share per annum on each outstanding share of Series B and Series A preferred stock, respectively, as and when declared by the board of directors. The dividend price per share was subject to adjustment for stock splits, stock dividends and reclassification. To date, we have not declared or paid dividends.
	Liquidation
	In the event of any liquidation, dissolution or winding up of the corporation, including a merger, acquisition in which our capital stock outstanding immediately prior to the transaction represented less than 50% of the outstanding shares of the surviving entity, a transaction or a series of transactions in which more than 50% of our voting power was transferred or a sale of all or substantially all of our assets, the holders of preferred stock were entitled to receive, prior and in preference to any distribution of assets to the holders of common stock, an amount equal to $2.29 for each share of Series B preferred stock and $0.47 for each share of Series A preferred stock held by them plus any declared but unpaid dividends. If our assets were insufficient to permit this payment, then the assets would be distributed ratably among the preferred stockholders. After this distribution, all assets would
	be ratably distributed to the common stockholders.
	The preferred stock agreements contained a provision that, in the event of a change in the control of the Company, would give the holders of the convertible preferred stock the right to receive a cash distribution equal to the liquidation preference on the convertible preferred stock. Due to these redemption characteristics, the convertible preferred stock has been presented as convertible preferred stock within the mezzanine section in the consolidated balance sheets.
	Conversion
	Each share of preferred stock was convertible at the option of the holder into such number of shares of Class B common stock determined by dividing its stated value by the conversion price at the time of conversion. The conversion price was equal to the original issue price as adjusted for stock splits, stock dividends, recapitalization, mergers, dilutive issuances and other transactions having a similar effect. All shares of preferred stock were automatically converted into shares of Class B common stock upon the closing of our IPO on a 1:1 basis.
	Redemption
	The convertible preferred stock was not redeemable by us or at the option of the preferred stockholder.

Each holder of Class B common stock is entitled to ten votes per share and each holder of Class A common stock is entitled to one vote per share. At its discretion, the board of directors may declare dividends on shares of common stock, subject to the rights of our preferred stockholders, if any. Upon liquidation or dissolution, holders of common stock will receive distributions only after preferred stock preferences have been satisfied.
	In May 2013, upon the closing of our IPO, 6,585,153 shares of Series B convertible preferred stock and 10,831,164 shares of Series A convertible preferred stock converted into 17,416,317 shares of our Class B common stock. We issued 6,230,000 shares of Class A common stock in the IPO. In addition, 3,200,000 shares of Class B common stock (including 2,000,000 shares of Class B common stock issued upon the conversion of our preferred stock) held by our existing stockholders were converted into Class A common stock and sold in the IPO.
	Donation to Tableau Foundation
	In December 2012, our board of directors approved the establishment of the Tableau Foundation, a donor-advised charitable fund, which included the donation of 150,000 shares of Class B common stock. We recorded a charge of $1.9 million for the value of the donated shares to general and administrative expense for the year ended December 31, 2012 based on the value of our stock at that date. We had no similar expenses in the years ended December 31, 2013 or 2011.

Stock-Based Compensation	'
	Stock-Based Compensation
	Our 2004 Equity Incentive Plan (the “2004 Plan”) authorizes the granting of options to purchase shares of Class B common stock, RSUs and other stock-based awards to our employees, consultants, officers and directors. In December 2012, we modified the 2004 Plan to increase the number of shares of Class B common stock authorized thereunder to 26,473,282. Our 2013 Equity Incentive Plan (the “2013 Plan” and, together with the 2004 Plan, the “Plans”), which was a successor to our 2004 Plan, authorizes the granting of options to purchase shares of our Class A common stock, RSUs and other stock-based awards to our employees, consultants, officers and directors. Options granted under the Plans may be incentive or nonstatutory stock options. Incentive stock options may only be granted to employees. The term of each option is stated in the award agreement, but shall be no more than 10 years from the date of grant. The board of directors determines the period over which options and RSUs become vested. Currently, the vesting period for our options and RSUs is typically four years.
	A summary of the option activity under the Plans during the year ended December 31, 2013 is presented below:
		Options Outstanding
		Shares		Weighted Average Exercise Price Per Share			Weighted-Average Remaining Contractual Term	Aggregate Intrinsic Value
							(in years)	(in thousands)
	Balances at December 31, 2012	15,398,221		$	4.92
	Options granted	1,341,550		23.18
	Options exercised	(4,182,114	)	2.52
	Options canceled	(8,125	)	7
	Options forfeited	(313,132	)	8.92
	Balances at December 31, 2013	12,236,400		$	7.64		7.4	$	749,944
	Vested and expected to vest at December 31, 2013	11,870,827		$	7.5		7.3	$	729,272
	Exercisable at December 31, 2013	5,786,352		$	3.79		6	$	376,947
	The stock options are exercisable at a price equal to the market value of the underlying shares of common stock on the date of the grant. For periods prior to the IPO this value was determined by our board of directors. After the IPO, this value was determined by reference to the closing price of our Class A common stock on the New York Stock Exchange on the date of grant. The weighted-average grant date fair value of stock options granted in 2013, 2012 and 2011 was $10.78, $4.65 and $2.74, respectively. The total fair value of options vested during 2013, 2012 and 2011 was $11.6 million, $3.8 million, and $1.2 million, respectively. The total intrinsic value of options exercised during 2013, 2012 and 2011 was $197.6 million, $7.6 million and $0.8 million, respectively.
	We grant RSU awards to our employees, officers and non-employee directors under the provisions of the 2013 Plan. The fair value of an RSU is determined by using the closing price of our Class A common stock as reported on the New York Stock Exchange on the date of grant. An RSU award entitles the holder to receive shares of the Company’s Class A common stock as the award vests, which is generally based on length of service. The Company's non-vested RSUs do not have nonforfeitable rights to dividends or dividend equivalents.
	The following provides a summary of our RSU activity during the year ended December 31, 2013:
		Number of Shares Underlying Outstanding RSUs		Weighted-Average Grant-Date Fair Value per RSU
	RSUs outstanding at December 31, 2012	—		$	—
	RSUs granted	575,350		64.04
	RSUs vested	—		—
	RSUs forfeited	(1,000	)	53.82
	Non-Vested outstanding at December 31, 2013	574,350		$	64.06
	Stock-based compensation expense is amortized on a straight-line basis over the vesting period. As of December 31, 2013, total unrecognized compensation expense, adjusted for estimated forfeitures, related to stock options and unvested RSUs was approximately $65.2 million which is expected to be recognized over a period of 3.3 years.
	The number of shares available for equity based awards (including stock options and RSUs) are available for issuance as follows:
		Shares Available for Grant
	Balance at December 31, 2012	6,907,924
	Granted	(1,916,900	)
	Canceled	8,125
	Forfeited	314,132
	Balance at December 31, 2013	5,313,281
	Valuation Assumptions
	All stock-based payments to employees are measured based on the grant date fair value of the awards and recognized in the consolidated statements of operations over the period during which the employee is required to perform services in exchange for the award (generally the four year vesting period of the award). We estimate the fair value of RSUs granted by using the closing price of our Class A common stock as reported on the New York Stock Exchange on the date of grant. We estimate the fair value of stock options granted using the Black-Scholes option-valuation model. For the years ended December 31, 2013, 2012 and 2011, the fair value of options was estimated using the Black-Scholes option pricing model with the following assumptions:
		Year Ended December 31,
		2013		2012		2011
	Risk-free interest rates	1.11	%	0.69	%	1.55	%
	Expected term	5 years		5 years		5 years

	Expected volatility	46.8	%	49	%	52.1	%
	The weighted-average, risk-free interest rate is based on the rate for a U.S. Treasury zero coupon issue with a term that approximates the expected life of the option grant at the date closest to the option grant date. The expected term represents the period that our stock-based awards are expected to be outstanding. The expected term assumptions were determined based on actual experience adjusted for expected employee exercise behavior.
	For periods prior to our IPO, there was no active external or internal market for our common shares. We lack sufficient historical volatility of our share price, accordingly, we base our volatility on an estimate of similar entities whose share prices are publicly available. We have not paid and do not expect to pay dividends. The estimation of stock awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period the estimates are revised. We consider many factors when estimating expected forfeitures, including the types of awards, employee class and historical experience. Forfeitures were estimated at the time of grant and revised if necessary in subsequent periods if actual forfeitures differed from those estimates. Actual results, and future changes in estimates, may differ substantially from our current estimates.
	Common Stock Warrant
	In May, 2013, 53,118 shares of Class B common shares were issued (net of 1,049 shares withheld for the exercise price) in conjunction with the exercise of fully-vested warrant to purchase 54,167 shares of our Class B common stock at an exercise price of $0.60 per share.

Earnings Per Share [Abstract]	'
Net Income (Loss) Per Share	'
	Net Income Per Share
	Immediately prior to the closing of our IPO, all outstanding shares of Series A preferred stock and Series B preferred stock were converted to shares of Class B common stock. We issued 6,230,000 shares of Class A common stock in the IPO. In addition, 3,200,000 shares of Class B common stock (including 2,000,000 shares of Class B common stock issued upon the conversion of our preferred stock) held by our existing stockholders were converted into Class A common stock and sold in the IPO. As a result, as of December 31, 2013, Class A and Class B common stock are the only outstanding classes of capital stock of the Company. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each holder of Class B common stock is entitled to 10 votes per share and each share of Class A common stock is entitled to 1 vote per share. Shares of Class B common stock may be converted into Class A common stock at any time at the option of the stockholder, and are automatically converted upon sale or transfer to Class A common stock, subject to certain limited exceptions.
	Net income per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities for periods in which we have net income. Holders of Series A preferred stock and Series B preferred stock were entitled to receive non-cumulative dividends at the per annum rate of $0.0282 and $0.1374 per share, payable prior and in preference to any dividends on any other shares of our stock. Holders of Series A preferred stock and Series B preferred stock did not have a contractual obligation to share in our losses. We consider our convertible preferred stock to be participating securities and, in accordance with the two-class method, earnings allocated to preferred stock and the related number of outstanding shares of preferred stock have been excluded from the computation of basic and diluted net income per common share. The computation of diluted net income per share does not assume conversion or exercise of potentially dilutive securities that would have an anti-dilutive effect on earnings. We utilize the if-converted method to compute diluted net income (loss) per common share when the if-converted method is more dilutive than the two-class method.
	Under the two-class method, net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period Series A and Series B convertible preferred stock non-cumulative dividends, between common stock and Series A and Series B convertible preferred stock. In computing diluted net income attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. Basic net income per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted-average number of common shares outstanding, including potential dilutive common shares assuming the dilutive effect of outstanding stock options using the treasury stock method.
	The following table presents the computation of basic and diluted net income per share attributable to common stockholders:

Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates include depreciable lives for property and equipment, stock-based compensation, income taxes, accrued liabilities and collectability of accounts receivable. Actual results could differ from those estimates.
Foreign Currency Translation	'
	Foreign Currency
	The financial statements of our foreign subsidiaries with a functional currency other than U.S. dollars have been translated into U.S. dollars. Assets and liabilities of these subsidiaries are translated at the exchange rate in effect at each period-end. Income statement amounts are translated at the average rate of exchange prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included in other comprehensive income (loss).

	Initial Public Offering
	On May 22, 2013, we completed our initial public offering ("IPO") whereby 9,430,000 shares of Class A common stock were sold to the public at a price of $31.00 per share. We sold 6,230,000 shares of Class A common stock and the selling stockholders sold 3,200,000 shares of Class A common stock. We received aggregate proceeds of $177.0 million from the IPO, net of underwriters’ discounts and commissions, and offering expenses. Upon the closing of the IPO, all shares of our outstanding convertible preferred stock automatically converted into shares of Class B common stock.
Segments	'
	Segments
	We follow the authoritative literature that established annual and interim reporting standards for enterprise’s operating segments and related disclosures about its products and services, geographic regions and major customers.
	We operate our business as one operating segment. Our chief operating decision makers (“CODM”) are our Chief Executive Officer and Chief Financial Officer, who review financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources
Revenue Recognition	'
	Revenue Recognition
	We generate revenues primarily in the form of software license fees and related maintenance and services fees. License fees include perpetual, term and subscription license fees. Maintenance and services fees primarily consist of fees for maintenance services (including support and unspecified upgrades and enhancements when and if they are available), training, and professional services that are not essential to functionality of the software.
	We recognize revenues when all of the following conditions are met:
	•	there is persuasive evidence of an arrangement;
	•	the software or services have been delivered to the customer;
	•	the amount of fees to be paid by the customer is fixed or determinable; and
	•	the collection of the related fees is probable.
	We use click-through license agreements, signed agreements and purchase orders as evidence of an arrangement. We deliver all of our software electronically. Electronic delivery occurs when we provide the customer with access to the software and license key via a secure portal. We assess whether the fee is fixed or determinable at the outset of the arrangement. Our typical terms of payment are due 30 days from delivery. We assess collectability based on a number of factors such as collection history and creditworthiness of the customer. If we determine that collectability is not probable, revenue is deferred until collectability becomes probable, generally upon receipt of cash.
	Substantially all of our software licenses are sold in multiple-element arrangements that include maintenance and may include professional services and training.
	Vendor specific objective evidence (“VSOE”) of the fair value is not available for software licenses as they are never sold without maintenance. VSOE of the fair value generally exists for all undelivered elements and any services that are not essential to the functionality of the delivered software. We account for delivered software licenses under the residual method.
	Maintenance agreements consist of fees for providing software updates on a when and if available basis and technical support for software products (“post-contract support” or “PCS”) for an initial term, generally one year. We have established VSOE of the fair value for maintenance on perpetual licenses based on stated substantive renewal rates or the price when sold on a standalone basis. Stated renewal rates are considered to be substantive if they are at least 15% of the actual price charged for the software license. VSOE of the fair value for standalone sales is considered to have been established when a substantial majority of individual sales transactions within the previous 12 months period fall within a reasonably narrow range, which we have defined to be plus or minus 15% of the median sales price of actual standalone sales transactions.
	License arrangements may include professional services and training. In determining whether professional services and training revenues should be accounted for separately from license revenues, we evaluate whether such services are considered essential to the functionality of the software using factors such as the nature of the software products; whether they are ready for use by the customer upon receipt; the nature of the services, which typically do not involve significant customization to or development of the underlying software code; the availability of services from other vendors; whether the timing of payments for license revenues coincides with performance of services; and whether milestones or acceptance criteria exist that affect the realizability of the software license fee. Revenues related to training are billed on a fixed fee basis and accordingly recognized as training services are delivered. Payments received in advance of services performed are deferred and recognized when the related services are performed.
	To date, professional services have not been considered essential to the functionality of the software. The VSOE of fair value of our professional services and training is based on the price for these same services when they are sold separately. Revenues related to professional services are billed on a time and materials basis and, accordingly, are recognized as the services or training are performed.
	When software is licensed for a specified term or on a subscription basis, fees for support and maintenance are generally bundled with the license fee over the entire term of the contract. In these cases, we do not have VSOE of the fair value for support and maintenance. Revenues related to term license fees are recognized ratably over the contract term beginning on the date the customer has access to the software license key and continuing through the end of the contract term.
	We do not offer refunds and therefore have not recorded any sales return allowance for any of the periods presented. Upon a periodic review of outstanding accounts receivable, amounts that are deemed to be uncollectable are written off against the allowance for doubtful accounts.
	We account for taxes collected from customers and remitted to governmental authorities on a net basis and exclude them from revenues
Risks and Uncertainties	'
	Risks and Uncertainties
	Inherent in our business are various risks and uncertainties, including our limited operating history and development of advanced technologies in a rapidly changing industry. These risks include our ability to manage our rapid growth and our ability to attract new customers and expand sales to existing customers, as well as other risks and uncertainties. In the event that we do not successfully implement our business plan, certain assets may not be recoverable, certain liabilities may not be paid and investments in our capital stock may not be recoverable. Our success depends upon the acceptance of our technology, development of sales and distribution channels, and our ability to generate significant revenues from the use of its technology.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	We consider all highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value. We maintain cash and cash equivalent balances which exceed the insured limits by the Federal Deposit Insurance Corporation.
Accounts Receivable	'
	Accounts Receivable
	Accounts receivable consist of amounts billed currently due from customers. Our accounts receivable are subject to collection risk. Our gross accounts receivable is reduced for this risk by a provision for doubtful accounts. This provision is for estimated losses resulting from the inability of our customers to make required payments. It is an estimate and is regularly evaluated for adequacy by taking into consideration a combination of factors. We look at factors such as past collection experience, credit quality of the customer, age of the receivable balance, and current economic conditions. These factors are reviewed to determine whether a provision for doubtful accounts should be recorded to reduce the receivable balance to the amount believed to be collectible.
	Activity related to our provision for doubtful accounts was as follows:
		Year Ended December 31,
		2013			2012			2011
		(in thousands)
	Balance at the beginning of the period	$	307		$	135		$	21
	Bad debt expense	789			321			133
	Accounts written off	(291		)	(149		)	(19		)
	Balance at the end of the period	$	805		$	307		$	135
Property and Equipment	'
	Property and Equipment
	Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets generally ranging from three to seven years. Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in the consolidated statements of operations. Maintenance and repairs that do not improve or extend the lives of the respective assets are charged to expense in the period incurred.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	We evaluate the recoverability of long-lived assets in accordance with authoritative guidance on accounting for the impairment or disposal of long-lived assets. We evaluate long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. Such impairment is recognized in the event the carrying value of such assets exceeds their fair value. If the carrying value of the net assets assigned exceeds the fair value of the assets, then the second step of the impairment test is performed in order to determine the implied fair value. No impairment of long-lived assets occurred in the periods presented.
Fair Value	'
	Fair Value
	We establish fair value of our assets and liabilities using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and using a fair value hierarchy based on the inputs used to measure fair value. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash equivalents, accounts receivable, accounts payable, and accrued and other current liabilities, due to their short-term nature.
Software Development Costs	'
	Software Development Costs
	Software development costs associated with the development of new products, enhancements of existing products and quality assurance activities consists of employee, consulting and other external personnel costs. The costs incurred internally from the research and development of computer software products are charged to expense until technological feasibility has been established for the product. Once technological feasibility is established, all software costs are capitalized until the product is available for release to customers. Judgment is required in determining when technological feasibility of a product is established. To date, we have determined that technological feasibility of software products is reached shortly before the products are released. Costs incurred after establishment of technological feasibility have not been material, and therefore, we have expensed all research and development costs as they were incurred. Research and development expenses primarily consist of
	personnel related costs attributable to our research and development personnel and allocated overhead.
	We capitalize certain costs relating to software acquired, developed, or modified solely to meet our internal requirements and for which there are no substantive plans to market the software. To date, we have not capitalized any such costs.
Intangible Asset Costs	'
	Intangible Asset Costs
	Costs related to filing and pursuing patent and trademark applications are expensed as incurred, as recoverability of such expenditures is uncertain. These intangible asset-related legal costs are reported as a component of general and administrative expenses.
Advertising Expenses	'
	Advertising Expenses
	We have expensed all advertising costs as incurred and classify these costs as sales and marketing expenses. Advertising expenses for the years ended December 31, 2013, 2012 and 2011 were $4.9 million, $3.0 million, and $1.7 million, respectively.
Deferred Offering Costs	'
	Deferred Offering Costs
	Deferred offering costs, consisting of legal, accounting and other fees and costs relating to the IPO, were capitalized and included in deposits and other noncurrent assets in the consolidated balance sheets. The deferred offering costs were offset against our IPO proceeds upon the closing of our IPO. There were $0.3 million of capitalized deferred offering costs as of December 31, 2012, and no similar costs as of December 31, 2013.
Income Taxes	'
	Income Taxes
	Our deferred tax assets are determined based on temporary differences between the financial reporting and income tax basis of assets and liabilities and are measured using the tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that the deferred tax assets will not be realized.
	We determine whether our uncertain tax positions are more likely than not to be sustained upon examination based on the technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the consolidated financial statements is reduced by the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority.
Concentrations of Credit Risk	'
	Concentrations of Credit Risk
	Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We extend credit to customers based upon an evaluation of the customer’s financial condition and generally collateral is not required. As of December 31, 2013, no individual customer accounted for 10% or more of total accounts receivable. As of December 31, 2012, one customer accounted for 10% or more of total accounts receivable. For the years ended December 31, 2013, 2012 and 2011, no individual customer represented 10% or more of our total revenues.
Stock-Based Compensation	'
	Stock-Based Compensation
	Compensation expense related to stock-based transactions, including employee and non-employee director stock option and restricted stock unit (“RSU”) awards, is measured and recognized in the financial statements based on fair value. The fair value of each RSU award is based on the number of shares subject to the RSU grant and the closing price of our Class A common stock as reported on the New York Stock Exchange on the date of grant.
	The fair value of each stock option award is determined at the date of grant by applying the Black-Scholes option pricing model. This model utilizes the estimated value of our underlying Class A common stock and Class B common stock (together, “common stock”) at the measurement date, the expected or contractual term of the option, the expected volatility of our common stock, risk-free interest rates and expected dividend yield of our common stock. Prior to our initial public offering in May 2013, because our stock was not publicly traded we estimated the fair value of our common stock. Our board of directors considered numerous objective and subjective factors to determine the fair value of our common stock at each meeting at which awards were approved. The factors included, but were not limited to: (i) contemporaneous third-party valuations of our common stock; (ii) the prices, rights, preferences and privileges of our preferred stock that was then outstanding relative to those of our common stock; (iii) the lack of marketability of our common stock; (iv) our actual operating and financial results; (v) current business conditions and projections; and (vi) the likelihood of achieving a liquidity event, such as an initial public offering or merger or acquisition, given prevailing market conditions. After the completion of our initial public offering, our common stock has been valued by reference to the closing price of our Class A common stock on the New York Stock Exchange.
	Measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instruments vest. We recognize compensation expense for only the portion of awards expected to vest. Therefore, management applied an estimated forfeiture rate that was derived from historical employee termination behavior. If the actual number of forfeitures differs from the estimates, adjustments to stock-based compensation expense may be required in future periods.
Fair Value Measurements	'
	Fair Value Measurements
	We categorize assets and liabilities recorded at fair value on our consolidated balance sheets based upon the level of judgment associated with inputs used to measure their fair value. The levels of the fair value hierarchy are as follows:
	•	Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
	•	Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or quoted prices
	for identical or similar instruments in markets that are not active and model-derived valuations in
	which all significant inputs and significant value drivers are observable in active markets.
	•	Level 3—Inputs are unobservable inputs based on our own assumptions and valuation
	techniques used to measure assets and liabilities at fair value. The inputs require significant
	management judgment or estimation.
	Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.
Recent Accounting Pronouncements	'
	In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists, or ASU 2013-11. ASU 2013-11 requires entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when settlement in this manner is available under the tax law. ASU 2013-11 is effective for public calendar year end companies for the first quarter of 2014, and applied prospective with early adoption permitted.  As of December 31, 2013, we have elected early adoption and have presented $3.4 million of unrecognized tax benefit as a reduction to deferred income tax assets in our consolidated balance sheet.
	As an “emerging growth company”, the Jumpstart Our Business Startups Act allows us to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies.
