What Founder Vesting Is

Founder vesting is a schedule that makes you earn your own shares over time, so that if you leave the company early, you forfeit the equity you have not yet earned. It sounds strange, since you founded the company, but it exists to protect the people who stay from a cofounder who walks away with a huge stake after six months of work.

Without vesting, a cofounder who quits early keeps every share they were granted at formation, even though the remaining founders now do all the work. Vesting fixes that by returning unearned shares to the company. It is standard, it is expected, and refusing it is a red flag to both investors and cofounders.

This is one of the terms that comes up the moment you take real money. Before that conversation, you need investors at the table. Round Funded helps you find the active, stage-matched investors who will actually get you there.

This is general information, not legal advice. Vesting terms have real tax and legal consequences (including the 83(b) election), so have a startup attorney set up or review your vesting.


The Standard 4-Year Schedule With a 1-Year Cliff

The market-standard founder vesting schedule is four years with a one-year cliff, meaning you earn nothing for the first year, then 25% at the one-year mark, then the rest monthly. This structure has become the near-universal default for a reason: it filters out early quitters while rewarding people who commit.

How the timeline works:

  • The cliff (year one): you vest zero shares until your first anniversary. Leave before then, and you walk away with nothing.
  • The cliff date (month 12): 25% of your shares vest all at once.
  • Monthly thereafter (years two to four): the remaining 75% vests in equal monthly increments, roughly 1/48th of your total per month.
  • Full vesting (year four): you own 100% of your granted shares outright.

The cliff is the key mechanism. It means a cofounder who leaves at month eleven forfeits everything, which protects the company from someone who is not truly committed. After the cliff, vesting smooths out month by month so departures are handled fairly.


Why Investors Require Vesting

Investors require founder vesting because they are betting on the founding team staying to build the company, and vesting is what keeps that team locked in. When a VC writes a check, the single biggest risk is a founder leaving. Vesting is their insurance.

The logic from the investor's side:

  • It keeps founders committed. Unvested equity is a powerful reason to stay through the hard years.
  • It protects against a walkaway. If a cofounder leaves, their unvested shares return to the pool instead of sitting on a dead cap table.
  • It keeps the cap table clean. A departed founder holding a large vested-and-gone stake makes the next round harder. Vesting minimizes that.

Investors will almost always require founders to be on a vesting schedule as a condition of the round, and they often "re-set" or refresh vesting at the financing. This is normal. What you negotiate is the details: acceleration, credit for time served, and the treatment of a termination.

To understand how vested and unvested shares show up on your ownership record, read our guide to reading a cap table.


Terms Founders Should Negotiate

You can and should negotiate the protective details of your vesting, especially acceleration provisions and credit for time already worked. Accepting a vanilla schedule without these protections leaves real value on the table.

The terms that matter most:

TermWhat it doesWhy it protects you
Vesting creditCounts time you already worked pre-financingYou are not reset to zero at the round
Single-trigger accelerationVests shares on an acquisitionYou are not fired the day after a sale
Double-trigger accelerationVests shares on acquisition AND if you are let goStandard, balanced protection
Acceleration on termination without causeVests some shares if you are pushed outGuards against a bad-faith firing

Double-trigger acceleration (you vest your remaining shares if the company is acquired AND you are terminated within a window) is the most common and most balanced protection. It means an acquirer cannot simply fire you to claw back your unvested equity. Push for it.

Step by Step: Setting Up Founder Vesting

Here is the practical path to getting your vesting right.

  1. Line up your round first. Use Round Funded to find active, stage-matched investors and build the competition that gives you leverage on terms.
  2. Set vesting at formation, with a lawyer. The cleanest time to put cofounders on a vesting schedule is at incorporation, before any conflict exists.
  3. File your 83(b) election on time. For founders granted stock subject to vesting, this election must be filed within 30 days. Missing it can create a serious tax bill. Get legal help.
  4. Use the 4-year, 1-year-cliff default. It is what investors and cofounders expect. Deviating without a strong reason invites scrutiny.
  5. Negotiate acceleration. Push for double-trigger acceleration and credit for time already worked when the financing round resets vesting.
  6. Document everything. Every founder's schedule, cliff date, and acceleration terms should be in signed agreements, not a handshake.

Frequently Asked Questions

Why do founders need a vesting schedule?

Vesting protects the founders who stay from a cofounder who leaves early with a large stake. It makes each founder earn their shares over time, so unearned equity returns to the company if someone walks away. Investors also require it to keep the founding team committed through the build.

What is the standard founder vesting schedule?

Four years with a one-year cliff. You vest nothing for the first year, then 25% at the one-year mark, then the remaining 75% monthly over the next three years. This is the near-universal default that investors and cofounders expect. Anything unusual will draw questions.

What is a vesting cliff?

A cliff is an initial period, usually one year, during which you vest zero shares. If you leave before the cliff date, you forfeit all of your equity. At the cliff, a chunk (typically 25%) vests at once, then vesting continues monthly. It filters out founders who are not truly committed.

Can investors reset my vesting when I raise?

Yes, investors often refresh or re-set founder vesting as a condition of the financing. This is standard. What you negotiate is credit for time already worked and acceleration provisions, so you are not simply reset to zero. Having competing offers via Round Funded gives you leverage here.

What is double-trigger acceleration?

Double-trigger acceleration vests your remaining unvested shares if two things happen: the company is acquired AND you are terminated within a set window afterward. It stops an acquirer from firing you to reclaim your equity. It is the most common and balanced founder protection to negotiate.

What is an 83(b) election and why does it matter?

An 83(b) election lets you pay tax on your restricted stock at grant, when it is worth almost nothing, instead of as it vests at a higher value. It must be filed with the IRS within 30 days of the grant. Missing the deadline can be very costly, so handle it with a lawyer. This is not legal advice.


Earn Your Company, Then Raise for It

Founder vesting can feel insulting at first, being asked to earn shares in a company you started, but it is one of the fairest structures in startup life. It protects the committed against the flighty, keeps the cap table clean, and gives investors the confidence to back your team.

Accept the standard schedule, negotiate the acceleration terms that protect you, and get a lawyer to set it up. Then focus on the thing that actually triggers all of this: landing the round.
