The purpose of the Annual Meeting will be the following:

To ratify the selection by the audit committee of our board of directors of Ernst & Young LLP as the independent registered public accounting firm of Wayfair Inc. for its fiscal year ending December 31, 2015.



3.

To transact such other business as may properly come before the Annual Meeting or any adjournment or postponement thereof.

        The foregoing items of business are more fully described in the Proxy Statement. Only stockholders who owned our Class A common stock or Class B common stock at the close of business on March 26, 2015 can vote at the Annual Meeting or any adjournments that take place.

        Our board of directors recommends that you vote FOR the election of the director nominees named in Proposal No. 1 of the Proxy Statement and FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm as described in Proposal No. 2 of the Proxy Statement.

        This year we are using the Internet as our primary means of furnishing proxy materials to our stockholders. Accordingly, most stockholders will not receive paper copies of our proxy materials. Instead we are mailing our stockholders a Notice Regarding the Availability of Proxy Materials, or Notice, with instructions for accessing the proxy materials and voting over the Internet, by telephone or by mail. The Notice also provides information on how stockholders may request paper copies of our proxy materials. We believe electronic delivery of our proxy materials and our 2014 Annual Report will help us reduce the environmental impact and costs of printing and distributing paper copies and improve the speed and efficiency by which our stockholders can access these materials.

        Your vote is very important. Whether or not you plan to attend the virtual Annual Meeting, we encourage you to read our proxy materials and submit your proxy or voting instructions as soon as possible over the Internet, telephone or by mail.

        In addition, you are entitled to vote on any other matters that are properly brought before the Annual Meeting.

How do I vote?

Stockholder of Record (Shares Registered in Your Name)

        If, on the Record Date, your shares were registered directly in your name with the transfer agent for our common stock, Computershare Trust Company, N.A., then you are a stockholder of record. As a stockholder of record, you may vote at the Annual Meeting or vote by proxy. Whether or not you plan to participate in the Annual Meeting, we urge you to vote by proxy over the Internet, by telephone or by mail as instructed below to ensure your vote is counted.

Vote by Internet

        Before the Annual Meeting—Go to www.proxyvote.com

        Use the Internet to transmit your voting instructions and for electronic delivery of information up until 11:59 P.M. eastern time on May 19, 2015, the day before Annual Meeting. Please have your Notice in hand when you access the website and then follow the instructions.

        During the Annual Meeting—Go to www.virtualshareholdermeeting.com/Wayfair

        You may attend the Annual Meeting via the Internet and vote during the Annual Meeting. Please have your Notice in hand when you access the website and then follow the instructions.

        Use any touch-tone telephone to transmit your voting instructions up until 11:59 P.M. eastern time on May 19, 2015, the day before the Annual Meeting. Please have your Proxy Card in hand when you call and then follow the instructions.

Beneficial Owner (Shares Registered in the Name of Broker, Bank or Other Agent)

        If, on the Record Date, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in "street name" and the Notice or these proxy materials are being forwarded to you by that organization. The organization

3

Table of Contents

holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, because you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid Proxy Card from your broker or other agent. Please follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker, bank or other agent to request a Proxy Card.

Who counts the votes?

        Broadridge Investor Communication Solutions, Inc. has been engaged as our independent agent to tabulate stockholder votes, or Inspector of Elections. If you are a stockholder of record, your executed Proxy Card is returned directly to Broadridge for tabulation. As noted above, if you hold your shares through a broker, your broker returns one Proxy Card to Broadridge on behalf of all its clients.

How are votes counted?

        Votes will be counted by the Inspector of Elections, who will separately count "For" and "Abstain" votes and broker non-votes. In addition, with respect to the ratification of the appointment of Ernst & Young as the independent registered public accounting firm, the Inspector of Elections will count the number of "Against" votes.

What are "broker non-votes"?

        Broker non-votes occur when a beneficial owner of shares held in "street name" does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed "non-routine." Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker or nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker or nominee can still vote the shares with respect to matters that are considered to be "routine," but not with respect to "non-routine" matters. In the event that a broker, bank, custodian, nominee or other record holder of common stock indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular proposal, then those shares will be treated as broker non-votes with respect to that proposal. Accordingly, if you own shares through a nominee, such as a broker or bank, please be sure to instruct your nominee how to vote to ensure that your vote is counted on each of the proposals.

Which ballot measures are considered "routine" or "non-routine?"

        The ratification of the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2015 (Proposal 2) is considered routine under applicable rules. A broker or other nominee may generally vote on routine matters, and therefore no broker non-votes are expected to exist in connection with Proposal 2. The election of directors (Proposal 1) is considered non-routine under applicable rules. A broker or other nominee cannot vote without instructions on non-routine matters, and therefore there may be broker non-votes on Proposal 1.

How many votes are needed to approve the proposal?

        With respect to Proposal No. 1, the election of directors, the nine nominees receiving the highest number of votes will be elected. Only votes "For" will affect the outcome of this proposal.

        With respect to Proposal No. 2, the affirmative vote of the majority of votes cast is required for approval. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

Table of Contents

How many votes do I have?

        On each matter to be voted upon, you have one vote for each share of Class A common stock you own as of the Record Date and ten votes for each share of Class B common stock you own as of the Record Date.

What if I complete a Proxy Card but do not make specific choices?

        If we receive a proxy instruction from you over the Internet, by telephone or by mail that does not specify how your shares are to be voted, your shares will be voted "For" the election of each of the nine nominees for director, and "For" the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm. If any other matter is properly presented at the Annual Meeting, your designated proxy, if any, will vote your shares using his or her best judgment.

Who is paying for this proxy solicitation?

        We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors, officers and employees may also solicit proxies in person, by telephone or by other means of communication. Directors, officers and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one Notice?

        If you receive more than one Notice, your shares are registered in more than one name or are registered in different accounts. In order to vote all the shares you own, you must vote pursuant to the instructions on each Notice.

Can I change my vote after submitting my proxy?

        Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of three ways:

•

You may submit another properly completed proxy with a later date.



•

You may send a written notice that you are revoking your proxy to us at Wayfair Inc., 4 Copley Place, 7^th Floor, Boston, MA 02116, Attention: Secretary.



•

You may attend the Annual Meeting and vote online. Simply attending the Annual Meeting will not, by itself, revoke your proxy.

        If your shares are held by your broker, bank or other agent, you should follow the instructions provided by them.

When are stockholder proposals due for the 2016 Annual Meeting of Stockholders?

        If you are interested in submitting a proposal for potential inclusion in the proxy statement for our 2016 Annual Meeting of Stockholders, you must follow the procedures outlined in Rule 14a-8 of the Securities Exchange Act of 1934, as amended, or the Exchange Act. To be eligible for inclusion in the proxy statement, we must receive your stockholder proposal or information about your proposed director candidate at the address noted below no later than December 12, 2015.

What is the quorum requirement?

        A quorum of stockholders is necessary to hold a valid Annual Meeting. On the Record Date, there were 40,113,179 shares of Class A common stock and 43,316,043 shares of Class B common stock outstanding and entitled to vote. A quorum will be present if stockholders holding a majority of the voting power of the shares of our Class A common stock and Class B common stock (voting together as a single class) entitled to vote are present at the Annual Meeting or represented by proxy.

        Your shares will be counted towards the quorum only if you submit a valid proxy or vote at the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, either the chairperson of the Annual Meeting or a majority in voting power of the stockholders entitled to vote at the Annual Meeting, present or represented by proxy, may adjourn the Annual Meeting to another time or place.

How can I find out the results of the voting at the Annual Meeting?

        Voting results will be announced by the filing of a Current Report on Form 8-K with the Securities and Exchange Commission, or SEC, within four business days after the Annual Meeting.

PROPOSAL NO. 1
ELECTION OF DIRECTORS

        Our board of directors, or board, is comprised of nine individuals. Unless the board determines that vacancies on the board (including vacancies created by increases in the number of directors) shall be filled by the stockholders, and except as otherwise provided by law, vacancies on the board may be filled only by the affirmative vote of a majority of the directors then in office, although less than a quorum, or by a sole remaining director. A director elected by the board to fill a vacancy shall serve for the remainder of the full term of the director in which the vacancy was created or occurred and until such director's successor is elected and qualified.

        The individuals below have been nominated to serve as directors and have each agreed to stand for reelection. Each director elected will hold office from the date of their election by the stockholders until the subsequent annual meeting of stockholders or until their successor is elected and has been qualified, or until such director's earlier death, resignation or removal.

        Shares represented by executed proxies will be voted, unless abstained, for the election of the nine nominees named below. In the event that any nominee should be unavailable for election as a result of an unexpected occurrence, such shares will be voted for the election of such substitute nominee as the board may propose. Each person nominated for election has agreed to serve if elected, and management has no reason to believe that any nominee will be unable to serve.

        Directors are elected by the affirmative vote of a plurality of the votes cast at the Annual Meeting. The nine nominees receiving the most "FOR" votes among votes properly cast in person or by proxy will be elected to the board as directors. You may vote "FOR" or "ABSTAIN" on each of the nominees for election as director. Shares represented by properly submitted proxy card will be voted on Proposal 1 "FOR" the election of the nominees named herein to the board of directors at the Annual Meeting, unless otherwise marked. A broker non-vote or a properly executed proxy marked "ABSTAIN" with respect to the election of a director will not be voted with respect to such director, although it will be counted for purposes of determining whether there is a quorum.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE

PROPOSAL NO. 2
RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        The audit committee of our board of directors has engaged Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2015, and is seeking ratification of such selection by our stockholders at the Annual Meeting. Ernst & Young LLP has audited our financial statements since the year ended December 31, 2012. Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

        Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm. However, the audit committee is submitting the selection of Ernst & Young LLP to our stockholders for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, the audit committee will reconsider whether or not to retain Ernst & Young LLP. Even if the selection is ratified, the audit committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and our stockholders.

Principal Accountant Fees and Services

        The following table provides information regarding the fees incurred to Ernst & Young LLP during the years ended December 31, 2013 and December 31, 2014. All fees described below were approved by the audit committee.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

        Our audit committee adopted, and our board of directors ratified, a policy that became effective upon the closing of our initial public offering in October 2014 under which the audit committee must pre-approve all audit and permissible non-audit services to be provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. Pre-approval would generally be requested annually, with any pre-approval detailed as to the particular service, which must be classified in one of the four categories of services listed above. The audit committee may also, on a case-by-case basis, pre-approve particular services that are not contained in the annual pre-approval request. In connection with this pre-approval policy, the audit committee also considers whether the categories of pre-approved services are consistent with the rules on accountant independence of the Securities and Exchange Committee, or SEC, and the Public Company Accounting Oversight Board. The audit committee has pre-approved all services performed since our policy on pre-approval of audit and non-audit services was adopted.

        In order for Proposal 2 to be approved, holders of a majority of the votes properly cast at the Annual Meeting must vote "FOR" Proposal 2. Abstentions and broker non-votes are not votes cast and will not be counted either "FOR" or "AGAINST" the proposal. Therefore, abstentions and broker non-votes will have no effect on the proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THIS PROPOSAL NO. 2.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

        The material in this report is not "soliciting material," is not deemed "filed" with the SEC, and is not to be incorporated by reference into any filing of Wayfair Inc. under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended.

        The primary purpose of the audit committee is to oversee our financial reporting processes on behalf of our board. The audit committee's functions are more fully described in its charter, which is available at the Investor Relations section of our website, located at investor.wayfair.com under the link for "Corporate Governance". Management has the primary responsibility for our financial statements and reporting processes, including our systems of internal controls. Ernst & Young LLP, our independent registered public accounting firm for fiscal year 2014, is responsible for expressing an opinion on the conformity of our audited financial statements with generally accepted accounting principles. In fulfilling its oversight responsibilities, the Audit Committee reviewed with management and Ernst & Young LLP the audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014.

        The Audit Committee also discussed with Ernst & Young LLP the matters that are required to be discussed by Auditing Standard No. 16, Communications with Audit Committees. Ernst & Young LLP has also provided the Audit Committee the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence, and the Audit Committee has discussed with Ernst & Young LLP that firm's independence. The Audit Committee has concluded that Ernst & Young LLP's provision of audit and non-audit services to Wayfair and its affiliates is compatible with Ernst & Young's independence. Finally, the audit committee discussed with Ernst & Young LLP, with and without management present, the scope and results of Ernst & Young LLP's audit of such financial statements.

        Based on these reviews and discussions, the audit committee has recommended to our board that such audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2014 for filing with the SEC. The audit committee also has engaged Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2015 and is seeking ratification of such selection by the stockholders.

CORPORATE GOVERNANCE

Code of Business Conduct and Ethics

        Our board has adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of the code may be found at the Investor Relations section of our website, located at investor.wayfair.com under the link for "Corporate Governance". In addition, we intend to post on the Corporate Governance section of our website all disclosures that are required by law or the New York Stock Exchange, or NYSE, listing standards concerning any amendments to, or waivers from, any provision of the code. Information included on or accessible through our website is not incorporated by reference herein.

Corporate Governance Guidelines

        Our board adopted corporate governance guidelines to ensure that the board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of the Company's stockholders. The Corporate Governance Guidelines set forth the practices the board intends to follow with respect to board composition and selection, board meetings and involvement of senior management, succession planning, and board committees and compensation. A copy of the Corporate Governance Guidelines may be found at the Investor Relations section of our website, located at investor.wayfair.com under the link for "Corporate Governance".

Independence of the Board of Directors

        Our board of directors has determined that all of our directors, other than Messrs. Shah and Conine, qualify as "independent" directors in accordance with the listing requirements of the NYSE. Each of Messrs. Shah and Conine is not considered independent because he is an employee of the Company.

Leadership Structure of the Board

        Our board of directors is currently co-chaired by Niraj Shah, our Chief Executive Officer, and Steven Conine, our Chief Technology Officer. Our board has established the position of lead independent director and elected Mr. Kumin our lead independent director. Our bylaws and Corporate Governance Guidelines provide our board of directors with flexibility to combine or separate the positions of chairman of the board and Chief Executive Officer and/or utilize a lead director in accordance with its determination that one or the other structure would be in the best interests of our company. Our board of directors has concluded that our proposed leadership structure is appropriate at this time. However, our board of directors will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Role of Board in Risk Oversight Process

        Risk assessment and oversight are an integral part of our governance and management processes. Our board of directors encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings, and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the board of directors at regular board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such

risks. Our board of directors does not have a standing risk management committee, but rather administers this oversight function directly through our board of directors as a whole, as well as through various standing committees of our board of directors that address risks inherent in their respective areas of oversight. In particular, our board of directors is responsible for monitoring and assessing strategic risk exposure. Our audit committee is responsible for overseeing our major financial risk exposures and the steps our management has taken to monitor and control these exposures. The audit committee also monitors compliance with legal and regulatory requirements. Our compensation committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. In addition, our nominating and governance committee monitors the effectiveness of our corporate governance guidelines and consider and approve or disapprove any related party transactions.

Board Committees

        Our board has established three standing committees—audit, compensation and nominating and corporate governance—each of which operates under a charter that has been approved by our board and that satisfies the applicable standards of the SEC and NYSE.

Executive Compensation and Employment Arrangements

        For a description of the compensation arrangements we have with our executive officers, please read the section titled "Executive Compensation, Discussion and Analysis."

Policies and Procedures for Related Party Transactions

        Our board of directors has adopted written policies and procedures for the review of any transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which Wayfair (including any of its subsidiaries) was, is or will be, a participant, the amount involved exceeds $120,000 in any one fiscal year, and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a "related party," had, has or will have a direct or indirect material interest.

        If a related party proposes to enter into such a transaction, arrangement or relationship, which we refer to as a "related party transaction," the related party will be required to report the proposed related party transaction to our general counsel. The policy will call for the proposed related party transaction to be reviewed and, if deemed appropriate, approved by our audit committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance approval of a related party transaction requiring the audit committee's approval is not feasible, then the transaction may be preliminarily entered into by management upon prior approval of the transaction by the chairperson of the audit committee subject to ratification of the transaction by the audit committee at the committee's next regularly scheduled meeting. If the transaction is not so ratified, the policy will require management to make all reasonable efforts to cancel or annul such transaction. Any related party transactions that are ongoing in nature will be reviewed annually.

        A related party transaction reviewed under the policy will be considered approved or ratified if it is authorized by the audit committee after full disclosure of the related party's interest in the transaction. In reviewing and approving any such transactions, the audit committee will be tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm's length transaction and the extent of the related party's interest in the transaction.

        Several of the transactions described in this section occurred prior to the adoption of the policy.

EXECUTIVE COMPENSATION DISCUSSION AND ANALYSIS

Executive Summary

        This Executive Compensation Discussion and Analysis provides an overview and analysis of the elements of our compensation program for our named executive officers identified below, the material compensation decisions made under that program and reflected in the executive compensation tables that follow this Executive Compensation Discussion and Analysis and the material factors considered in making those decisions. As a company dedicated to a pay-for-performance culture, we intend to provide our named executive officers with compensation that is significantly performance-based. Our executive compensation program is designed to align executive pay with our performance on both short and long-term bases, link executive pay to specific, measurable results intended to create value for stockholders, and utilize compensation as a tool to assist us in attracting and retaining the high-caliber executives that we believe are critical to our long-term success. We believe that the key to our success is the long term stockholder value that is created by our employees. Our compensation philosophy is weighted towards providing equity awards, and we believe that focusing on long-term equity incentive awards will allow us to achieve our goals. For example, we provide each of our employees, including our named executive officers, with an equity award upon hire, which we believe motivates the employee to think of themselves as an owner of the Company and that, as an owner, their respective decisions will make a difference to stockholder value.

        Compensation for our named executive officers consists primarily of the elements, and their corresponding objectives, identified in the following table.

        The compensation committee has primary authority to determine and approve compensation decisions with respect to our named executive officers. In alignment with the objectives set forth above, the compensation committee, upon recommendations from our Chief Executive Officer and Chief Technology Officer, or Co-Founders, regarding the compensation of all the named executive officers excluding themselves, determines overall compensation and its allocation among the elements described above, in reliance upon the judgment and general industry knowledge of its members obtained through years of service with comparably-sized companies in our and similar industries.

Our Named Executive Officers

        For the year ended December 31, 2014, our named executive officers, or NEOs, are:

•

Niraj Shah, Co-Founder, Chief Executive Officer, Director (Co-Chairman)



•

Steven Conine, Co-Founder, Chief Technology Officer, Director (Co-Chairman)

Michael Fleisher, Chief Financial Officer



•

Nicholas Malone, Chief Administrative Officer



•

John Mulliken, Senior Vice President, Strategic Initiatives, and



•

Stephen Oblak, Senior Vice President, General Manager, Wayfair.com.

        Our compensation decisions for the NEOs in 2014 are discussed below in relation to each of the above-described elements of our compensation program. The discussion below is intended to be read in conjunction with the executive compensation tables and related disclosures that follow this Executive Compensation Discussion and Analysis.

Compensation Overview

        Our overall compensation program is structured to attract, motivate and retain highly qualified executives by paying them competitively, consistent with our success and their contribution to that success. We believe compensation should be structured to ensure that a significant portion of an executive's compensation opportunity will be related to factors that directly and indirectly influence stockholder value. Our pay practices are focused on providing our executives with a significant amount of their compensation in the form of upfront equity grants, which we believe attracts and retains the highest caliber employees and aligns our employees' long-term interests with our stockholders' interests. In addition, a NEO's compensation may include additional equity grants based on performance or promotions. Our NEOs, who are all employed on an at-will basis, receive limited perquisites and, except for our Co-Founders who currently do not receive bonuses, moderate annual cash bonuses based on personal performance, rather than short-term corporate goals. We offer a qualified 401(k) retirement plan with employer matching, but do not offer nonqualified deferred compensation plans, supplemental executive retirement plan benefits or formal cash severance programs.

Determination of Compensation

        The compensation committee has the primary authority to help determine and approve compensation paid to our NEOs. The compensation committee is charged with, among other things, reviewing compensation policies and practices to ensure adherence to our compensation philosophies and that the total compensation paid to our NEOs is fair, reasonable and competitive, taking into account our position within our industry, including our comparative performance, and our NEOs' level of expertise and experience in their respective positions. In furtherance of the considerations described above, the compensation committee is primarily responsible for determining base salary, assessing the performance of the Chief Executive Officer and other NEOs for each applicable performance period and approving the equity awards and cash bonuses to be paid to our Chief Executive Officer and other NEOs for each year. To aid the compensation committee in making its determinations, the Co-Founders provide recommendations at least annually to the compensation committee regarding the compensation of all NEOs, excluding themselves and the NEOs' managers provide individual performance assessments that are used in determining awards under our annual cash incentive program. The performance of our NEOs is reviewed at least annually by the compensation committee, and the compensation committee approves each NEO's compensation at least annually.

        In determining compensation for our NEOs, the compensation committee considers each NEO's particular position and responsibility and relies upon the judgment and industry experience of its members, including their knowledge of competitive compensation levels in our industry. We believe that base salaries should be competitive with salaries for executive officers in similar positions and with similar responsibilities in our marketplace. Neither we nor the compensation committee used a compensation consultant to determine NEO compensation in 2014 or benchmarked the compensation for our NEOS against the compensation of our peers.

Elements of our Executive Compensation Program

Base Compensation for 2014

        Our base salary is designed to recognize the duties and responsibilities of each executive office and the experience, knowledge, ability and skill of the NEO that holds each such position. However, the Co-Founders elected to reduce their base salaries to $80,000 for 2014 from $480,000 in 2013. Otherwise the base salaries of our NEOs did not change from 2013 to 2014, because our goal was to weigh compensation towards providing equity awards to ensure that a significant portion of an NEOs' compensation opportunity is related to factors that directly and indirectly influence stockholder value. The compensation committee believes that base salaries are an important component of our executive compensation program and are critical in attracting and retaining executive talent. The compensation committee reviews base salaries of our NEOs in the first quarter of each year, which is the same cycle on which annual base salaries are generally reviewed for other employees generally. In setting annual base salaries, the compensation committee takes into consideration the recommendations of our Co-Founders, our company-wide target for base salary increases for all employees, their knowledge of market and competitive salary information, inflation, changes in the scope of an executive officer's job responsibilities, and other components of compensation and other relevant factors. The base salaries for our NEOs for 2014 are set forth in the following table:

Annual Cash Bonuses

        Messrs. Fleisher, Malone, Mulliken and Oblak are eligible to participate in a discretionary cash incentive program which provides the opportunity to earn a cash bonus award that ranges from 0 to 25% of base salary. The award is based on the assessment by each participant's manager of his individual performance. In consideration of their leadership of the Company's finance, human resources and legal functions and their services related to the Company's initial public offering, each of Messrs. Fleisher and Malone received a cash bonus award of 25% of his base salary. Mr. Mulliken received a cash bonus award of 25% of his base salary in consideration of his performance in directing many of the Company's strategic initiatives, including his role leading Wayfair's international business. Mr. Oblak also received a cash bonus award of 25% of his base salary in consideration of his successful management of Wayfair.com, the Company's largest brand.

Equity Awards

        A large portion of our NEOs' total compensation is stock-based compensation in order to tie compensation with long-term stockholder value. As such, named executive officers receive sizable equity awards at the time of hire, additional awards at the time of a promotion, and are eligible to receive periodic awards at other times at the discretion of our compensation committee. These awards generally vest over a period of 5 years in order to ensure continued employment and to align our NEOs' interests with the long-term interests of our stockholders. Equity awards held by our NEOs may accelerate as a result of termination of employment in connection with a change in control, as discussed below under the heading "Employment and Change in Control Arrangements". NEOs do not necessarily receive equity awards on an annual basis. Therefore, a NEO's compensation may fluctuate

25

Table of Contents

materially from year to year depending on whether a grant was made in a particular year. Since 2011, we have issued Restricted Stock Units, or RSUs, as our stock-based compensation vehicle. We believe RSUs tie our NEOs' long-term interests with our stockholders' interests and help efficiently manage overall stockholder dilution from stock awards. RSU grant amounts and vesting for NEOs, whether for new hires or in respect of subsequent grants, are established by the compensation committee after receiving recommendations from our Co-Founders.

        In April 2014, each of Messrs. Malone and Oblak received an RSU grant for 30,000 shares in connection with his promotion to Senior Vice President. The RSUs vest over a period of five years, with 20% of the RSUs vesting on the first anniversary of the grant date and an additional 1/60^th of the original number of RSUs vesting in monthly installments thereafter, subject to the NEO's continued employment on each applicable vesting date and potential accelerated vesting as discussed below under the heading "Employment and Change in Control Arrangements." For more information on these awards, see the "Grants of Plan-Based Awards in 2014" table below.

Defined Contribution Plans

        We maintain a defined contribution plan that is tax-qualified under Section 401(k) of the Internal Revenue Code (the "Code"), which we refer to as the 401(k) Plan. The 401(k) Plan permits our eligible salaried employees to defer receipt of portions of their eligible salaries, subject to certain limitations imposed by the Code, by making contributions to the 401(k) Plan, including flexible compensation contributions, Roth contributions, catch-up contributions and after-tax contributions.

        We provide matching contributions to the 401(k) Plan in an amount equal to 100% of each participant's pre-tax contribution up to a maximum of 4% of the participant's annual eligible salary, subject to certain other limits. In 2014, we made a company contribution to the 401(k) Plan in an amount equal to approximately $2.4 million. Participants are 100% vested in all contributions, including company contributions. The 401(k) Plan is offered on a nondiscriminatory basis to all of our salaried employees, including NEOs.

        The compensation committee believes that matching and company contributions assist us in attracting and retaining talented employees and executives. The 401(k) Plan provides an opportunity for participants to save money for retirement on a tax-deferred basis and to achieve financial security, thereby promoting retention.

Employment and Change in Control Arrangements


Employment Agreements

        We have entered into employment agreements with certain of our NEOs, the material terms of which are described below.

        Messrs. Shah and Conine:    We entered into amended and restated employment letter agreements with Messrs. Shah and Conine on May 6, 2014, which entitled each of Messrs. Shah and Conine to receive an annual base salary, subject to periodic increases (but not decreases) at the discretion of the board of directors. In 2013, base salary for each of Messrs. Shah and Conine was $480,000. For 2014, each base salary was reduced to $80,000 at the request of Messrs. Shah and Conine. The letter agreements also entitle them to participate in the employee benefit plans and programs that we offer to our other full-time employees. Messrs. Shah's and Conine's employment letter agreements contain restrictive covenants which prohibit them from competing with us or soliciting our employees, consultants or suppliers for twenty-four months following termination of employment. Pursuant to Messrs. Shah's and Conine's employment letter agreements, if we terminate their employment without cause (as defined in the employment letter agreements) or if they resign for good reason (as defined in the employment letter agreements) they will receive healthcare benefit continuation until the earlier of (i) the last day of the applicable COBRA period and (ii) twenty-four months following termination. In addition, pursuant to the terms of their RSU award grants, in the event Messrs. Shah or Conine is terminated for any reason other than for cause within twelve months following a change in control, 50% of their unvested RSUs will vest.

        Mr. Fleisher:    We entered into an employment letter agreement with Mr. Fleisher on October 2, 2013, which was amended on May 5, 2014 and which entitles him to an initial annual base salary of $350,000, subject to periodic review and adjustment. The employment letter agreement also provides Mr. Fleisher with an annual bonus between 0-20% of his annual salary under our annual cash incentive program and the opportunity to participate in the employee benefit plans and programs that we offer to our other full-time employees. For 2014, the annual bonus Mr. Fleisher was eligible to receive under our annual cash incentive program ranged between 0 to 25% of his annual salary. Mr. Fleisher's employment letter agreement also contains a provision requiring him to sign the Company's non-compete, non-solicitation, non-disclosure and invention agreement designed for all employees, which agreement generally provides that he will not disclose confidential information of the Company nor solicit any employee, contractor, customer or supplier of the Company. In 2014, we memorialized Mr. Fleisher's right to receive reimbursement for his commuting-related expenses, which includes a gross-up for applicable taxes.

        Mr. Mulliken:    We entered into an employment letter with Mr. Mulliken on July 24, 2014 in connection with his assignment to work in Europe, which entitles Mr. Mulliken to receive an annual base salary of $265,000, subject to periodic review and adjustment. The employment letter also provides Mr. Mulliken with an annual bonus under our annual cash incentive program and the opportunity to participate in the employee benefit plans and programs that we offer to our other full-time employees. For 2014, the annual bonus Mr. Mulliken was eligible to receive ranged between 0 to 25% of his annual salary. In connection with his assignment to Europe, Mr. Mulliken is also entitled to tax equalization benefits related to his compensation earned abroad, payment of costs for preparation of his tax returns, and reimbursement for transportation and moving expenses. In consideration for Mr. Mulliken's continuing his assignment to Europe, we amended his employment letter effective April 1, 2015. Pursuant to this amendment, Mr. Mulliken is entitled to reimbursement for certain personal travel expense, payment to cover moving and relocation expenses related to his expected return to the United States upon completion of his assignment abroad, and payment for private school tuition and fees of Mr. Mulliken's children. Additionally, as part of this amendment and in consideration for Mr. Mulliken continuing his overseas assignment we agreed to pay Mr. Mulliken an additional $100,000, prorated and payable monthly for a period of one year commencing in July 2015, which shall be payable on the same schedule even if we terminate or reassign Mr. Mulliken.

        Certain of the compensation set forth above must be repaid to Wayfair in the event Mr. Mulliken leaves Wayfair voluntarily or is terminated for cause prior to the completion of his overseas assignment. Mr. Mulliken previously signed the Company's standard non-compete, non-solicitation, non-disclosure and invention agreement designed for all employees, which agreement generally provides that he will not disclose confidential information of the Company nor solicit any employee, contractor, customer or supplier of the Company.

Restricted Stock Unit Vesting

        The award agreements governing the NEOs' outstanding RSU awards provide that, in the event an NEO is terminated for any reason other than cause (excluding a resignation by the NEO or a termination as a result of the NEO's death or disability) within twelve (12) months following a change in control, with respect to Messrs. Shah, Conine, Mulliken and Oblak, 50% of the NEO's unvested RSUs will vest and, with respect to Messrs. Fleisher and Malone, 100% of the NEO's unvested RSUs will vest.

Other Elements of Compensation and Perquisites

        We maintain broad-based benefits that are provided to all employees, including our NEOs. These benefits include a 401(k) retirement savings plan with matching contributions, a group health plan, group term life insurance and wellness programs. The compensation received by our NEOs with respect

to these benefits is included in the Summary Compensation Table below. For more information about our 401(k) plan, see the discussion above under the heading "—Defined Contribution Plans." We also provide certain of our NEOs with certain personal benefits and perquisites, including commuting-related expense reimbursement for Mr. Fleisher and benefits related to Mr. Mulliken's international assignment to Europe, which we do not consider to be a significant component of executive compensation but which we recognize are an important factor in attracting and retaining talented executives. For more information regarding these benefits provided to Messrs. Fleisher and Mulliken, see the discussion above under the heading "—Employment Agreements."

See "Employment and Change in Control Arrangements" above for a description of these arrangements with our NEOs. In addition, pursuant to the terms of the award agreements governing their outstanding equity awards, our NEOs are entitled to accelerated vesting upon termination of their employment for any reason other than cause (excluding a resignation by the NEO or as a result of the NEO's death or disability) occurring within 12 months following a change in control. Assuming a hypothetical termination of employment effective as of December 31, 2014 by us without cause, by the executive for good reason or without cause within 12 months following a change in control, each of our NEOs would have received the following severance benefits:

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

        The following table sets forth certain information with respect to the beneficial ownership of our capital stock as of February 28, 2015, for:

•

each of our named executive officers;



•

each of our directors;



•

all of our directors and executive officers as a group; and



•

each holder of more than 5% of our Class A common stock or Class B common stock.

        Beneficial ownership is determined in accordance with the rules of the SEC and generally includes any shares over which a person exercises sole or shared voting or investment power. Shares of common stock issuable under options or warrants that are exercisable within 60 days after February 28, 2015 are deemed beneficially owned, and such shares are used in computing the percentage ownership of the person holding the options or warrants but are not deemed outstanding for the purpose of computing the percentage ownership of any other person. The information contained in the following table is not necessarily indicative of beneficial ownership for any other purpose, and the inclusion of any shares in the table does not constitute an admission of beneficial ownership of those shares. Unless otherwise indicated below, to our knowledge, all persons named in the table have sole voting and investment power with respect to their shares of common stock, except to the extent authority is shared by spouses under community property laws.

        Our calculation of the percentage of beneficial ownership is based on 37,199,841 shares of our Class A common stock and 46,192,680 shares of our Class B common stock outstanding as of February 28, 2015. This table is based upon information supplied by our directors, executive officers and holders of more than 5% of our Class A common stock or Class B common stock and information

ADDITIONAL INFORMATION

Householding of Proxy Materials

        The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single Notice or Proxy Statement addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.

        Brokers with account holders who are Wayfair stockholders may be "householding" our proxy materials. A single Notice or Proxy Statement may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you notify your broker or the Company that you no longer wish to participate in "householding."

        If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate proxy statement and annual report, you may (1) notify your broker, (2) direct your written request to: Wayfair Inc., 4 Copley Place, 7^th Floor, Boston, MA 02116, Attention: Secretary or (3) contact our Investor Relations department by telephone at 617-880-8108. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request "householding" of their communications should contact their broker. In addition, the Company will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the annual report and proxy statement to a stockholder at a shared address to which a single copy of the documents was delivered.

Other Matters

        As of the date of this Proxy Statement, the board of directors does not intend to present any matters other than those described herein at the Annual Meeting and is unaware of any matters to be presented by other parties. If other matters are properly brought before the meeting for action by the stockholders, proxies will be voted in accordance with the recommendation of the board or, in the absence of such a recommendation, in accordance with the judgment of the proxy holder.

Annual Reports

        The 2014 Annual Report to Stockholders is available at the Investor Relations section of our website, located at investor.wayfair.com. Requests for copies of our 2014 Annual Report to Stockholders may also be directed to the Secretary, Wayfair Inc., 4 Copley Place, 7^th Floor, Boston, MA 02116.

        We have filed our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 with the SEC. It is available free of charge at the SEC's web site at www.sec.gov. Upon written request by a Wayfair stockholder, we will mail without charge a copy of our Annual Report on Form 10-K, including the financial statements and financial statement schedules, but excluding exhibits. Exhibits to the Annual Report on Form 10-K are available upon payment of a reasonable fee, which is limited to our expenses in furnishing the requested exhibit.
