What Is a Founder Equity Vesting Agreement?

A founder equity vesting agreement is the document that makes founder shares conditional on staying and doing the work. The founder receives the full share count up front and owns it on paper, but the company keeps the right to buy back any shares that have not yet vested if the founder leaves. Vesting is usually measured over four years with a one-year cliff, which means nothing vests during the first twelve months and then a quarter of the grant vests at once, with the rest vesting in equal monthly installments after that.

The reason serious investors ask for this before writing a check is simple arithmetic. A cofounder who leaves after five months and keeps a third of the company permanently damages the cap table for everyone who stays, and no future round can fix it cleanly. Vesting turns that risk into a defined outcome. The same document also handles what happens in an acquisition through acceleration, restricts transfers of unvested shares, and reminds the founder about the Section 83(b) election, which has an unforgiving thirty-day deadline and no relief for missing it.

When to Use This Template

  • You are issuing founder shares at company formation and want them earned over time
  • Cofounders are splitting equity and need protection if one of them leaves early
  • Investors have asked that founder stock be subject to vesting before a financing round closes
  • An existing founder holds fully vested stock and the team is retroactively imposing a schedule
  • You are bringing on a late cofounder or advisor who will receive restricted stock rather than options

Founder Equity Vesting Agreement

  1. 1. 1. Parties

    This Founder Equity Vesting Agreement (the "Agreement") is entered into as of [EFFECTIVE DATE] between [COMPANY NAME], a [STATE] corporation with its principal office at [COMPANY ADDRESS] (the "Company"), and [FOUNDER NAME], an individual residing at [FOUNDER ADDRESS] (the "Founder"). The Company and the Founder are referred to individually as a "Party" and together as the "Parties." This Agreement is entered into in connection with the issuance of shares described in Section 2 and, where applicable, supplements the restricted stock purchase agreement, subscription agreement, or board resolution dated [ISSUANCE DOCUMENT DATE]. Each Party represents that it has the authority to enter into this Agreement, and the Company represents that its board of directors has approved the terms below. Notices are effective when delivered to the addresses above or to [COMPANY EMAIL] and [FOUNDER EMAIL].

  2. 2. 2. Shares Subject to Vesting

    The Founder holds [TOTAL SHARE COUNT] shares of [SHARE CLASS, e.g., Common Stock] of the Company, purchased or issued at a price of [PURCHASE PRICE PER SHARE] per share, representing approximately [OWNERSHIP PERCENTAGE] of the outstanding equity of the Company on a fully diluted basis as of the Effective Date (the "Shares"). Of the Shares, [VESTED AT SIGNING COUNT] are fully vested as of the Effective Date in recognition of [PRIOR CONTRIBUTION DESCRIPTION, e.g., work performed before incorporation], and the remaining [UNVESTED SHARE COUNT] shares are unvested and subject to the vesting schedule and repurchase right in this Agreement (the "Unvested Shares"). The Shares are issued subject to the certificate of incorporation, the bylaws, and any stockholders agreement of the Company. Any shares issued in respect of the Shares through a stock split, dividend, recapitalization, or similar event are subject to the same vesting terms.

  3. 3. 3. Vesting Schedule and Cliff

    The Unvested Shares vest over a total period of [VESTING PERIOD, e.g., four years] measured from [VESTING COMMENCEMENT DATE], which may precede the Effective Date to credit earlier service. No Unvested Shares vest before the Founder completes [CLIFF PERIOD, e.g., twelve months] of Continuous Service measured from the Vesting Commencement Date (the "Cliff"). On the first day after the Cliff is satisfied, [CLIFF PERCENTAGE, e.g., 25 percent] of the Unvested Shares vest in a single installment. Thereafter, the remaining Unvested Shares vest in equal monthly installments of [MONTHLY VESTING FRACTION, e.g., 1/48th of the original Unvested Share count] on the same day of each month, so that all Unvested Shares are fully vested at the end of the Vesting Period. If the Founder ceases Continuous Service before the Cliff is satisfied, no Unvested Shares vest and all of them remain subject to repurchase under Section 6. Fractional shares are rounded down until the final installment.

  4. 4. 4. Continuous Service and Leaves of Absence

    For purposes of this Agreement, "Continuous Service" means uninterrupted service to the Company as a founder, employee, officer, director, or full-time consultant, at a commitment level of not less than [MINIMUM COMMITMENT, e.g., 40 hours per week]. Continuous Service is not interrupted by a change in the capacity in which the Founder serves, provided there is no break in service. Vesting continues during an approved leave of absence for up to [PAID LEAVE PERIOD, e.g., 90 days] or for any longer period required by applicable law or by a written company leave policy. If an approved leave extends beyond that period, vesting is suspended as of the first day after it and resumes on the date the Founder returns to active service, with the vesting schedule extended by the length of the suspension. Continuous Service ends on the last day the Founder actually performs services, not on the last day of any severance or notice period, unless the board determines otherwise in writing.

  5. 5. 5. Termination for Cause, Without Cause, and Good Reason

    This Agreement does not create any right to continued service, and the Founder serves at will unless a separate written employment agreement provides otherwise. "Cause" means, as determined in good faith by the board: (a) a material breach of this Agreement, of an invention assignment agreement, or of a fiduciary duty; (b) conviction of, or a plea of no contest to, a felony or a crime involving dishonesty; (c) fraud, embezzlement, or misappropriation of company property; (d) gross negligence or willful misconduct that materially harms the Company; or (e) continued failure to perform assigned duties that is not cured within [CAUSE CURE PERIOD, e.g., 30 days] after written notice. "Good Reason" means a material reduction in duties, title, or compensation, or a relocation of the principal workplace by more than [RELOCATION DISTANCE, e.g., 50 miles], without the consent of the Founder and after written notice and a [GOOD REASON CURE PERIOD, e.g., 30 day] cure opportunity. A resignation for Good Reason is treated as a termination without Cause for purposes of Section 8.

  6. 6. 6. Company Repurchase Right on Unvested Shares

    If the Continuous Service of the Founder ends for any reason, including resignation, termination with or without Cause, death, or disability, the Company has an irrevocable option to repurchase all or any portion of the Unvested Shares that have not vested as of the date service ends (the "Repurchase Right"). The repurchase price is the original price paid per share by the Founder, or, if the Shares were issued for services or other non-cash consideration, [NOMINAL REPURCHASE PRICE, e.g., $0.0001 per share], in each case without interest and regardless of the then-current fair market value of the Shares. Shares that have already vested are not subject to the Repurchase Right and remain the property of the Founder, subject to any separate transfer restrictions, right of first refusal, or co-sale obligation. The Repurchase Right applies equally to any securities into which the Unvested Shares are converted.

  7. 7. 7. Exercise of the Repurchase Right and Escrow

    The Company may exercise the Repurchase Right by delivering written notice to the Founder within [REPURCHASE EXERCISE WINDOW, e.g., 90 days] after Continuous Service ends, identifying the number of shares being repurchased and the aggregate price. Payment may be made by check, wire transfer, cancellation of indebtedness owed by the Founder to the Company, or any combination of these. The repurchase is effective on the date of the notice whether or not the certificates have been surrendered, and from that date the Founder has no further rights as a holder of the repurchased shares other than the right to receive the repurchase price. To secure performance, the certificates representing the Unvested Shares, together with a stock assignment signed in blank by the Founder, will be held in escrow by the Secretary of the Company or another escrow holder designated by the board, who will release vested shares to the Founder on written request at reasonable intervals. If the Company does not exercise the Repurchase Right within the exercise window, it lapses as to the shares not repurchased.

  8. 8. 8. Acceleration on a Change of Control

    If a Change of Control occurs while the Founder is in Continuous Service, [SINGLE TRIGGER PERCENTAGE, e.g., 25 percent] of the then-unvested Shares vest immediately before the transaction closes (single-trigger acceleration). If, within [DOUBLE TRIGGER WINDOW, e.g., 12 months] after a Change of Control, the Continuous Service of the Founder is terminated by the Company or its successor without Cause, or the Founder resigns for Good Reason, then [DOUBLE TRIGGER PERCENTAGE, e.g., 100 percent] of the then-unvested Shares vest immediately on the termination date (double-trigger acceleration). "Change of Control" means a merger, consolidation, sale of all or substantially all assets, or a transfer of more than [CONTROL THRESHOLD, e.g., 50 percent] of the voting power of the Company to a person or group that did not previously hold it, excluding an equity financing conducted primarily to raise capital and any reincorporation or holding-company reorganization. Acceleration under this section is conditioned on the Founder signing a general release of claims in a form reasonably acceptable to the Company if the board so requires.

  9. 9. 9. Restrictions on Transfer

    The Founder may not sell, assign, pledge, hypothecate, gift, or otherwise transfer any Unvested Shares, or any interest in them, and any attempted transfer is void and will not be recorded on the books of the Company. Vested Shares may be transferred only in compliance with applicable securities laws and only after complying with any right of first refusal, co-sale right, market standoff, or transfer approval requirement in the bylaws or in a stockholders agreement of the Company. A transfer to a revocable trust for estate planning, or to a family member who agrees in writing to be bound by this Agreement, is permitted with the prior written consent of the board, which will not be unreasonably withheld, and the transferred shares remain subject to the vesting schedule and the Repurchase Right. Certificates representing the Shares will bear legends referencing these restrictions and any applicable securities law restrictions.

  10. 10. 10. Voting Rights and Dividends

    Until the Repurchase Right is exercised, the Founder is the record owner of all of the Shares, including the Unvested Shares, and may vote them on all matters submitted to stockholders, subject to any voting agreement, proxy, or drag-along provision the Founder has signed. Cash dividends and other distributions paid on Unvested Shares will be [PAID CURRENTLY TO THE FOUNDER / HELD BY THE COMPANY AND RELEASED AS THE UNDERLYING SHARES VEST], and any distribution held back will be forfeited to the extent the underlying shares are repurchased. Stock dividends, split shares, and any securities received in exchange for Unvested Shares are subject to the same vesting schedule, Repurchase Right, escrow, and transfer restrictions as the shares they relate to, and will be delivered to the escrow holder. Nothing in this section limits the right of the Company to take corporate actions that affect all holders of the same class equally.

  11. 11. 11. Section 83(b) Election and Tax Matters

    The Founder understands that under Section 83 of the Internal Revenue Code, the excess of the fair market value of the Shares over the amount paid for them is generally taxed as ordinary income as the Shares vest, unless the Founder files an election under Section 83(b) with the Internal Revenue Service within thirty (30) days after the date the Shares are transferred to the Founder. That thirty-day deadline is set by statute, cannot be extended by the Company, and no relief is available for a late filing. The Founder is solely responsible for deciding whether to make the election, for preparing and timely filing it, and for retaining proof of mailing, and will deliver a copy of any filed election to the Company. The Company makes no representation about the tax consequences of the Shares or of any election, and the Founder has been advised to consult an independent tax adviser. A sample election form is attached as Exhibit A for convenience only.

  12. 12. 12. Intellectual Property Assignment and Confidentiality

    The Founder confirms that all inventions, software, designs, content, trademarks, know-how, and other intellectual property created by the Founder relating to the business of the Company, whether before or after the Effective Date, are assigned to the Company under the separate confidential information and invention assignment agreement dated [IP AGREEMENT DATE], and the Founder will sign that agreement concurrently if it is not already in place. Equity vesting under this Agreement does not by itself transfer any intellectual property, and the Company relies on that separate assignment. The Founder will promptly deliver to the Company all source code, domain names, accounts, credentials, and registrations held in a personal name, and will sign any further documents reasonably needed to perfect ownership. The Founder will keep the confidential information of the Company confidential during and after service, and a breach of the assignment or confidentiality obligations is grounds for termination for Cause.

  13. 13. 13. Amendment, Waiver, and General Provisions

    This Agreement, together with the issuance documents, the invention assignment agreement, and any stockholders agreement referenced here, is the entire understanding of the Parties about vesting of the Shares and supersedes any prior discussion, term sheet, or side letter on the subject. It may be amended only by a writing signed by the Founder and by an authorized officer of the Company acting with board approval, and any acceleration of vesting granted by the board must be recorded in the minutes. The failure of the Company to exercise the Repurchase Right or to enforce any provision on one occasion is not a waiver of that right later. If any provision is held unenforceable, the remainder stays in effect and the provision will be reformed to the minimum extent necessary. This Agreement binds and benefits the successors and permitted assigns of the Parties, including any acquirer of the Company.

  14. 14. 14. Governing Law and Dispute Resolution

    This Agreement is governed by the laws of the State of [GOVERNING STATE], without regard to conflict of laws rules, and matters of internal corporate governance are governed by the law of the state of incorporation of the Company. The Parties will first attempt to resolve any dispute through direct discussion for at least [NEGOTIATION PERIOD, e.g., 30 days]. Any dispute not resolved that way will be brought exclusively in the state or federal courts located in [VENUE COUNTY AND STATE], and each Party consents to personal jurisdiction and waives any objection to that venue. The Parties agree that money damages would be an inadequate remedy for a breach of the transfer restrictions or the Repurchase Right, and that the Company is entitled to seek specific performance and injunctive relief without posting a bond. The prevailing Party may recover reasonable attorney fees and costs.

  15. 15. 15. Signatures

    By signing below, each Party confirms that it has read this Agreement, has had the opportunity to consult independent legal and tax counsel, and agrees to be bound by its terms as of the Effective Date. COMPANY: [COMPANY NAME]. Signature: ______________________. Printed Name: [COMPANY SIGNER NAME]. Title: [TITLE]. Date: [DATE]. FOUNDER: Signature: ______________________. Printed Name: [FOUNDER NAME]. Date: [DATE]. SPOUSE CONSENT (if applicable in a community property state): Signature: ______________________. Printed Name: [SPOUSE NAME]. Date: [DATE]. This Agreement may be executed in counterparts, and electronic signatures have the same effect as original signatures.

  16. 16. Disclaimer

    This template is provided for general informational purposes only and is not legal or tax advice. Founder equity involves corporate, securities, and tax rules that differ by state and by the specific structure of your company, and mistakes are expensive and often permanent. The Section 83(b) election in particular carries a strict thirty-day statutory deadline that no one can extend for you. Have a licensed attorney and a tax adviser review any equity document before you sign or file anything. Use of this template does not create an attorney-client relationship with ScanContract.

Key Clauses Explained

What each important clause does — and what to watch out for before you sign.

The One-Year Cliff

Prevents any shares from vesting until the founder completes a full year of continuous service.

The cliff is binary and unforgiving: leave on day 364 and you keep nothing, leave on day 366 and you keep a quarter of the grant. Founders should check whether the vesting commencement date credits work done before incorporation, because that date can move the cliff by months. The company should confirm the cliff is measured from the commencement date rather than from signature, since those are often different. Anyone joining a team that already has traction should negotiate the commencement date before arguing about percentages.

Monthly Vesting After the Cliff

Vests the remainder of the grant in equal monthly installments across the balance of the vesting period.

Monthly vesting is founder-friendly compared with quarterly or annual installments, so check which one you actually signed. Confirm that the monthly fraction is measured against the original grant rather than against the post-cliff remainder, because the two produce different totals. Founders should also confirm that vesting continues while they are on an approved leave, and companies should confirm it stops when someone drops below the minimum commitment level.

Company Repurchase Right at Cost

Lets the company buy back unvested shares at the original purchase price when service ends.

This is the enforcement mechanism for the whole document, and it does not care why you left. Founders should note that the repurchase price is cost, not fair market value, so a departure right before a major round costs you the entire upside on the unvested portion. Check the exercise window, because a short one means the company must act quickly or lose the right. Confirm that already-vested shares are clearly outside the repurchase right, since sloppy drafting sometimes sweeps them in.

Single-Trigger and Double-Trigger Acceleration

Vests some or all unvested shares on a change of control, or on a qualifying termination after one.

Single-trigger vests on the deal itself, which founders love and acquirers hate because it removes the retention they are paying for. Double-trigger vests only if you are also terminated without cause or resign for good reason within the window after closing, which is the compromise most investors accept. If you have single-trigger on everything, expect it to be renegotiated during diligence, usually at the worst possible moment. Read the definition of good reason closely, because a narrow one makes double-trigger protection much weaker than it looks.

Definition of Cause

Sets the misconduct that lets the company end service and repurchase unvested shares without acceleration.

A broad cause definition that includes anything the board considers unsatisfactory performance turns founder equity into something the board can cancel at will. Founders should push for objective triggers, a written notice requirement, and a cure period for anything curable. Companies should keep fraud, felony conviction, and breach of the invention assignment agreement squarely inside the definition. Both sides should notice that acceleration usually disappears entirely when a termination is for cause.

Restrictions on Transfer of Unvested Shares

Blocks any sale, pledge, or gift of shares that have not yet vested and voids attempted transfers.

Founders sometimes try to move shares into a trust or to a family member without checking this clause, and the transfer is simply void. Confirm that permitted estate-planning transfers exist and that the transferee has to sign on to the same vesting terms. Companies should make sure the legends actually appear on the certificates, because unlegended shares create real problems in diligence. Also check how this interacts with any right of first refusal on vested shares.

Section 83(b) Election

Lets the founder elect to be taxed on the value of the shares at grant rather than as they vest.

The thirty-day deadline runs from the transfer of the shares and cannot be extended by anyone, including the IRS. Founders who miss it can face ordinary income tax on the spread at each vesting date, which is brutal if the company appreciates quickly. File it, keep proof of mailing, and give a copy to the company for its records. The company should not advise on whether to file, but it should remind the founder in writing that the clock is running.

Escrow of Certificates

Places the unvested share certificates and a blank stock assignment with an escrow holder until vesting.

This is administrative but it is what makes the repurchase right practical rather than theoretical. Founders should confirm there is a clear process for releasing vested shares on request, so their certificates are not left sitting in a drawer for four years. Companies should name the escrow holder and keep the signed blank assignment current. If the company uses an electronic cap table instead of paper certificates, make sure the agreement reflects that.

Frequently Asked Questions

What does a four-year vesting schedule with a one-year cliff actually mean?
It means the founder earns the shares over four years of service, and nothing at all is earned during the first twelve months. On the first anniversary of the vesting commencement date, twenty-five percent of the grant vests in one installment, and the remaining seventy-five percent vests in equal monthly pieces over the following thirty-six months. If the founder leaves before the anniversary, the company can buy back the entire grant at cost. It is the most common structure in United States startups for exactly that reason.
What is the 83(b) election and why does the thirty-day deadline matter so much?
An 83(b) election tells the IRS to tax the shares now, at their current low value, rather than taxing the increase in value each time a tranche vests. For founder stock issued at formation the value is usually near zero, so the tax cost of filing is minimal and the benefit can be enormous. The election must be filed with the IRS within thirty days of the share transfer, and that deadline is statutory with no extensions and no cure. Founders who miss it can owe ordinary income tax on the appreciation at every future vesting date, so file it immediately and keep proof of mailing.
What is the difference between single-trigger and double-trigger acceleration?
Single-trigger acceleration vests shares when a change of control happens, regardless of whether the founder stays with the acquirer. Double-trigger acceleration requires two events: the change of control, and then a termination without cause or a resignation for good reason within a defined window afterward. Acquirers strongly prefer double-trigger because it keeps the team in place after closing, while founders prefer single-trigger because it guarantees a payout. Many companies land on partial single-trigger acceleration plus full double-trigger, which is the structure in this template.
Can a founder who already owns fully vested shares be put on a vesting schedule?
Yes, and it happens regularly when a company raises its first priced round and investors require it. Because the founder is giving up something of value, the change has to be documented properly, and the tax treatment of the new arrangement should be reviewed before signing. Founders in this position usually negotiate credit for time already served through an earlier vesting commencement date, along with a portion vested at signing. Never do this on a handshake, since retroactive vesting is exactly the kind of term that gets disputed later.
What happens to unvested shares if a cofounder is fired or quits?
The company can exercise its repurchase right and buy back the unvested portion at the original purchase price, which is usually a fraction of a cent per share. Already-vested shares stay with the departing founder, subject to any right of first refusal or other transfer restriction in the stockholders agreement. Whether acceleration applies depends on the reason for departure and whether a change of control is involved. The company should exercise the repurchase right within the stated window, because letting it lapse leaves the departing founder holding unvested stock permanently.
