	1. The Company and Summary of Significant Accounting Policies and Estimates
	Business
	Marketo, Inc. (Marketo or the Company) was incorporated in the state of California on January 20, 2006. The Company was reincorporated in the state of Delaware on December 17, 2009. The Company operates from its headquarters in San Mateo, California and has operating subsidiaries in Ireland, Australia, Israel and Japan.
	Marketo is a provider of a cloud-based marketing software platform that enables organizations to engage in modern relationship marketing. The Company’s software platform is designed to enable the effective management, optimization and analytical measurement of marketing activities, enabling organizations to acquire new customers more efficiently, build stronger relationships with existing customers, improve sales effectiveness and drive faster revenue growth. On this platform, the Company delivers an easy to use, integrated suite of advanced applications. The Company generally offers its services on an annual subscription basis with quarterly or annual payment terms.
	Basis of Presentation
	The unaudited condensed consolidated financial statements and accompanying notes of the Company reflect all adjustments (all of which are normal and recurring in nature) that, in the opinion of management, are necessary for a fair presentation of the interim periods presented. The unaudited condensed consolidated financial statements include the accounts of Marketo and its wholly-owned and majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
	The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the entire year ending December 31, 2014. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (SEC). These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and related notes presented in the Company’s Annual Report on Form 10-K filed with the SEC on March 3, 2014. There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s audited consolidated financial statements for the fiscal year ended December 31, 2013.
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and 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. Such management estimates and assumptions include the estimated selling price for the various elements in our customer contracts, the allowance for doubtful accounts, stock-based compensation expense, useful lives of intangible assets, redemption value of redeemable non-controlling interests and the valuation of deferred tax assets. Actual results could differ materially from those estimates, and such differences could be material to the financial statements and affect the results of operations reported in future periods.
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740) - Presentation of an unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This amendment clarifies the guidance on the presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The adoption of this update in the first quarter of 2014 did not have a material impact to the consolidated financial position, results of operations, or cash flows.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective.  ASU 2014-09 also specifies the accounting for some costs to obtain or fulfill a contract with a customer. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method.  The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

	2. Joint Venture
	On February 19, 2014, the Company entered into an agreement with SunBridge Corporation and Dentsu eMarketing One K.K. (collectively, the Investors) to engage in the investment, organization, management and operation of a Japanese subsidiary (Marketo KK) of the Company that is focused on the sale of the Company’s products and services in Japan. The Investors contributed approximately $2.0 million (200,000,000 Japanese Yen) in cash in exchange for 35.4% of the outstanding common stock of Marketo KK. As of September 30, 2014, the Company owned approximately 64.6% of the outstanding common stock of Marketo KK. Furthermore, the Company and the Investors have agreed to subscribe to additional shares by contributing additional funding of approximately $2.3 million (237,480,955 Japanese Yen) and approximately $2.0 million (200,000,000 Japanese Yen), respectively, on or before April 1, 2015, at which point the Company and the Investors would own approximately 60.1% and 39.9% of the outstanding common stock in Marketo KK, respectively.
	Twenty percent of the common stock held by the Investors may be callable by the Company or puttable by the Investors beginning on the seventh anniversary of the initial capital contribution by the Investors. This percentage increases to forty percent and one hundred percent on the eighth and tenth anniversary, respectively.  Should the call or put option be exercised, the redemption value would be determined based on a prescribed formula derived from the relative revenues of Marketo KK and the Company and may be settled, at the Company’s discretion, with Company stock (with no limit on the shares that may be issued) or cash.  Additionally, the common stock held by the Investors may be callable or puttable following a change of control of the Company.  The redeemable non-controlling interests in Marketo KK is classified outside of permanent equity in the Company’s condensed consolidated balance sheet as of September 30, 2014, primarily due to the put right available to the redeemable non-controlling interest holders in the future which may be settled in cash or common stock of the Company. The balance of the redeemable non-controlling interests is reported at the greater of the initial carrying amount adjusted for the redeemable non-controlling interest’s share of earnings, or its estimated redemption value. The resulting changes in the estimated redemption amount (increases or decreases) are recorded with corresponding adjustments against retained earnings or, in the absence of retained earnings, additional paid-in-capital. The estimated redemption value of the call/put option embedded in the redeemable non-controlling interests was approximately $0.3 million at September 30, 2014.

Fair Value of Financial Instruments	'
	3. Fair Value of Financial Instruments
	The Company measures certain financial assets at fair value on a recurring basis based on a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy, as follows:
		·		Level 1 — Quoted prices in active markets for identical assets or liabilities.
		·		Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.
		·		Level 3 — Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.
	As of September 30, 2014 and December 31, 2013, financial assets measured at fair value on a recurring basis were comprised of money market funds and certificates of deposit included within cash and cash equivalents.
	The fair value of these financial assets was determined using the following inputs for the periods presented:

	7. Credit Facility
	In May 2012, the Company entered into a loan and security agreement with a bank related to an equipment facility providing the Company with an equipment line of up to $4.0 million. In June 2013, the Company entered into a first amendment to the loan and security agreement, which provided an additional line of credit for advances of up to $4.5 million. The interest rate associated with both lines of credit is the greater of 4% or three-quarters percentage points above the prime rate, as determined on the applicable funding date. For each equipment advance, the Company will pay interest only for approximately nine months. Subsequently, the Company will make thirty-six equal monthly payments of principal and interest. The loan is secured by a security interest on substantially all of the Company’s assets, including the equipment purchased with the advances, and excludes the Company’s intellectual property. The loan and security agreement contains customary events of default and provides that during the existence of an event of default, interest on the obligations could be increased by 5%.
	In May 2014, the Company entered into a second amendment to the loan and security agreement to amend various covenants. Under the second amendment the Company is required to maintain compliance with certain financial covenants, which include maintaining a minimum cash balance with the bank and various reporting covenants. As of September 30, 2014, the Company was in compliance with these covenants.  As of September 30, 2014 and December 31, 2013, the outstanding loan balance was $6.0 million and $7.6 million, respectively.
	There were no material changes in the Company’s commitments under the outstanding loan balance, as disclosed in the Company’s audited consolidated financial statements for the year ended December 31, 2013.

	Vested and expected to vest as of September 30, 2014				5,094		$	10.23		7.64	$	117,751
	The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the Company’s closing price of $32.30 as of September 30, 2014 for options that were in-the-money as of that date.
	Option awards generally vest over a four year period, with 25% vesting after one year from date of grant and monthly thereafter. Stock options granted under our 2006 Plan provided employee option holders with an early exercise provision, where in the event of termination any unvested shares purchased are subject to repurchase by the Company at the original purchase price. This right of repurchase lapses as the option vests. Options exercisable as of September 30, 2014 include options that are exercisable prior to vesting.
	The weighted average grant date fair value of options granted and the total intrinsic value of options exercised were as follows (in thousands, except weighted average grant date fair value):
			Nine Months

	Weighted average grant date fair value		$	20.79		$	4.44
	Total intrinsic value of options exercised		$	42,103		$	13,568
	The total estimated grant date fair value of options vested during the nine months ended September 30, 2014 was approximately $3.8 million.
	Determining Fair Value of Stock Options
	The fair value of each option grant is estimated on the date of grant using the Black-Scholes option valuation model. The following assumptions were used to estimate the fair value of options granted to employees:
			Three Months				Nine Months

	RSUs granted during the nine months ended September 30, 2014 are subject to a time-based vesting condition that ranges from 3 to 4 years.
	The aggregate intrinsic value of RSUs outstanding at September 30, 2014 was determined using the Company’s closing stock price of $32.30 per share as of September 30, 2014.
	The weighted average grant date fair value of RSUs granted and the total intrinsic value of RSUs that vested during the periods presented were as follows (in thousands, except weighted average grant date fair value):

	Employee Stock Purchase Plan
	The assumptions used to value employee stock purchase rights under the Black-Scholes model during the three and nine months ended September 30, 2014 and 2013 were as follows:

	10. Net Loss per Share
	Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less the weighted-average unvested common stock subject to repurchase or forfeiture as they are not deemed to be issued for accounting purposes. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including preferred stock, stock options, RSUs and employee stock purchase plan, to the extent they are dilutive.
	The following table sets forth the computation of the Company’s basic and diluted net loss per share of common stock under the two-class method attributable to common stockholders:
		Three Months						Nine Months
		Ended September 30,						Ended September 30,
		2014			2013			2014			2013

	Denominator:

	Less: Weighted-average unvested common shares subject to repurchase or forfeiture and shares held in escrow	(204		)	(176		)	(226		)	(176		)
	Weighted-average shares used in computing net loss per share of common stock, basic and diluted	40,668			37,054			40,157			20,144
	Net loss per share of common stock, basic and diluted	$	(0.31	)	$	(0.27	)	$	(0.96	)	$	(1.58	)
	The Company applied the two-class method to calculate its basic and diluted net loss per share of common stock, as its convertible preferred stock, common stock subject to repurchase and common stock held in escrow are participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common shareholders.
	However, the two-class method does not impact the net loss per share of common stock as the Company was in a loss position for each of the periods presented and preferred shareholders, holders of common stock subject to repurchase and common stock held in escrow do not have to participate in losses.
	Additionally, since the Company was in a loss position for each of the periods presented, diluted net loss per share is the same as basic net loss per share for each period, as the inclusion of all potential common shares outstanding would have been anti-dilutive. Potentially dilutive securities that were excluded from the diluted per share calculation because they would have been antidilutive were as follows:
		As of September 30,
		2014		2013
		(in thousands)
	Stock options to purchase common stock	5,529		7,360
	Employee stock purchase plan	132		257
	Common stock held in escrow	137		—

	11. Income Taxes
	For the three and nine months ended September 30, 2014, the Company recorded income tax expense of approximately $126,000 and $96,000, respectively, consisting primarily of foreign and state income taxes. The provision for income taxes for the three and nine months ended September 30, 2013 was approximately $9,000 and $46,000, respectively, consisting primarily of foreign and state income taxes.  Tax expense for the three and nine months ended September 30, 2014 increased over the respective prior periods due to the Company’s increased earnings in certain foreign jurisdictions.
	For the three and nine months ended September 30, 2014 and 2013, the provision for income taxes differed from the statutory amount primarily due to the Company realizing no benefit for current year losses, due to maintaining a full valuation allowance against the U.S. and selected foreign net deferred tax assets, while realizing state and foreign taxes currently payable.
	The realization of tax benefits of deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, in the periods the items are expected to be deductible or taxable. Based on the available objective evidence, the Company does not believe it is more likely than not that the U.S. Federal and state net deferred tax assets will be realizable. Accordingly, the Company has provided a full valuation allowance against the domestic net deferred tax assets and certain foreign jurisdictions with net deferred tax assets as of September 30, 2014 and December 31, 2013. The Company intends to maintain the remaining valuation allowance until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance. During the three and nine months ended September 30, 2014, there have been no material changes to the total amount of unrecognized tax benefits.

	The accounting principles guiding disclosures about segments of an enterprise and related information establishes standards for the reporting by business enterprises of information about operating segments, products and services, geographic areas, and major customers. The method of determining which information is reported is based on the way that management organizes the operating segments within the Company for making operational decisions and assessments of financial performance. The Company’s chief operating decision maker (the CODM) is considered to be the Company’s chief executive officer (CEO). The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance. As such, the Company is determined to be operating in one business segment.

Basis of Presentation	'
	Basis of Presentation
	The unaudited condensed consolidated financial statements and accompanying notes of the Company reflect all adjustments (all of which are normal and recurring in nature) that, in the opinion of management, are necessary for a fair presentation of the interim periods presented. The unaudited condensed consolidated financial statements include the accounts of Marketo and its wholly-owned and majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
	The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the entire year ending December 31, 2014. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (SEC). These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and related notes presented in the Company’s Annual Report on Form 10-K filed with the SEC on March 3, 2014. There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s audited consolidated financial statements for the fiscal year ended December 31, 2013.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and 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. Such management estimates and assumptions include the estimated selling price for the various elements in our customer contracts, the allowance for doubtful accounts, stock-based compensation expense, useful lives of intangible assets, redemption value of redeemable non-controlling interests and the valuation of deferred tax assets. Actual results could differ materially from those estimates, and such differences could be material to the financial statements and affect the results of operations reported in future periods.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740) - Presentation of an unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This amendment clarifies the guidance on the presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The adoption of this update in the first quarter of 2014 did not have a material impact to the consolidated financial position, results of operations, or cash flows.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective.  ASU 2014-09 also specifies the accounting for some costs to obtain or fulfill a contract with a customer. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method.  The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
