Vesting

A vesting schedule is an incentive program for employees that gives them benefits, usually stock options, when they have contractually fulfilled a specified term of employment with the company. The benefits can also be other assets, such as retirement funds. Vesting is a way for employers to keep top-performing employees aVesting is a way for people to earn ownership slowly over time. Instead of giving someone all their shares or benefits on day one, vesting spreads that ownership out across a set number of months or years. Only the part that has “vested” is truly theirs.

In a young company, vesting helps make sure that the people who stay, contribute, and build the business are the ones who actually keep their equity. It also protects the company if someone walks away too early. Founders, early employees, and investors all rely on vesting because it keeps everyone aligned and committed for the long haul.

A vesting schedule is also commonly used in inheritance law and real estate.

What does vesting mean?

Vesting is the process of earning ownership of something, usually equity or retirement benefits, over time. You don’t own everything upfront. Instead, you gain it piece by piece until you’re fully vested. Anything vested is yours. Anything unvested isn’t yours yet.

A lot of things can vest, like stock options, restricted stock units (RSUs), restricted stock, founder shares, and even retirement contributions. No matter the type of asset, the idea is the same: the longer you stay and contribute, the more you earn.

It’s also important to understand the difference between vested and unvested ownership.

• Vested means you’ve earned it, it’s yours to keep.
• Unvested means you haven’t earned it yet, and you could lose it if you leave the company early.

There are a few key terms you’ll see in any equity plan. The vesting period is the total time required to earn everything. A vesting date is the moment when a new portion of your equity becomes yours, typically at each monthly or yearly milestone. A vesting clause is the part of your agreement that spells out all the rules: when vesting starts, how long it lasts, and what happens if you leave.

Why startups use vesting?

First, vesting keeps co-founders committed. Everyone earns their shares over time, so no one can leave early and take a big chunk of the company with them. It keeps the whole founding team aligned and focused on building the business.

It also protects the cap table. Startups change quickly, and some people won’t stay long-term. Without vesting, someone who worked at the company for only a few months could still own a meaningful amount of equity. That can make hiring, fundraising, or restructuring much harder later on.

Investors expect vesting too. When VCs see a proper vesting plan, it signals to them that the team is serious and that the company is set up responsibly. This makes them feel more comfortable investing.

Most of all, vesting creates a fairer way to share ownership. People earn their equity based on the time and effort they put in. Those who stay and contribute the most end up owning the most, exactly how it should be in a growing startup.

Types of vesting schedules

Startups use different vesting schedules to determine how equity is earned over time. Here are the main ones and how they work.

Cliff vesting

With cliff vesting, nothing vests at first. You have to reach a certain point, usually one full year, before any of your equity becomes yours. When you hit that date, a big chunk vests all at once. After the cliff, the rest usually vests in smaller steps.

Graded vesting

Graded vesting spreads ownership out more evenly. After the first year (if there’s a cliff), you start vesting incrementally, often monthly. It’s a steady, predictable way to earn your equity.

Hybrid vesting

Hybrid vesting mixes different styles. A company might use a cliff and then switch to graded vesting, or combine time-based vesting with goal-based vesting. This approach offers greater flexibility when a standard schedule doesn’t work.

Other vesting options

Not every company sticks to the usual formats. Some use milestone-based vesting, where you earn equity upon completing a project or meeting a target. Others may offer immediate vesting for small grants or special situations. These are less common, but they exist when the company needs something more custom.

Founder vesting & Reverse vesting

Founder vesting is important for every startup, even if the founders created the company. It makes sure each founder earns their shares over time, just like the rest of the team. This helps keep everyone committed and prevents problems if someone leaves too early.

Most founder vesting is done through reverse vesting. With reverse vesting, founders get all their shares on day one, but they don’t fully own them yet. If a founder leaves before their shares vest, the company can repurchase the unvested shares. As time passes, more of those shares become theirs fully.

The standard setup for founders is four years of vesting with a one-year cliff. Nothing vests during the first year, and thereafter shares vest gradually, usually monthly. Investors expect this, and they always check founder vesting during due diligence. They want to see that the founders are committed and that no one can leave early with a big share of the company.

If founders skip vesting at the beginning, things can get messy. A founder might leave after a few months but still retain a large part in the company, which can scare off investors and make hiring harder. That’s why many teams end up resetting founder vesting before fundraising. Investors often ask for a fresh vesting schedule before they’re willing to invest.

Founder vesting differs from employee vesting. Employees usually get stock options or RSUs that vest over time. Founders usually get restricted stock tied to reverse vesting, and the stakes are higher because it affects the whole company’s future and investor confidence.

What is accelerated vesting? 

Accelerated vesting is when someone gets their unvested shares faster than planned. Instead of waiting months or years for those shares to vest, they become theirs right away. This usually happens during big events, such as when a company is sold or someone is let go without doing anything wrong.

Single-trigger acceleration

Single-trigger acceleration occurs when a single event triggers additional vesting. Most of the time, that event is the company's acquisition. So if the company gets bought, some unvested shares vest instantly.

Investors don’t always love this for founders, because it might encourage people to leave right after the sale.

Double-trigger acceleration

Double-trigger acceleration needs two events. The common setup is:

1. The company is acquired, and
2. The person is either let go or their role changes in a way that counts as termination.

Only when both things happen does the extra vesting kick in. Investors prefer this because it keeps the team around during the transition after a sale.

Partial vs. Full acceleration

Acceleration can work in different amounts:

• Partial acceleration means only some of the remaining unvested shares vest early, like 25%, 50%, or a few months of vesting.
• Full acceleration means everything vests at once.

Partial acceleration is more common because it feels fair while still protecting the company. Full acceleration is usually reserved for key people or special situations.

Vesting in a compensation plan?

In an employee stock option plan (ESOP), vesting determines when an employee can exercise their stock options. “Using” options means buying shares at the price the company sets.

Employees don’t get access to all their options at once. They earn the right to use them little by little, based on the vesting schedule. Many companies follow a simple setup: four years of vesting with a one-year cliff.

• Before the cliff, nothing vests.
• After the first year, a big chunk vests.
• Then the rest is vested in smaller monthly steps.

If someone leaves the company early, they only keep the options that have already vested.

Company policy requirements and employee disclosures

Every company needs clear rules explaining how vesting works. These details are usually written in the equity plan, the option grant, or the employee’s contract. The policies should explain things like:

• How long does the vesting period last
• If there’s a cliff
• How often does vesting happen
• What happens if the employee leaves
• How and when they can exercise their options

Employees also need written information about their grant, the vesting terms, the number of shares, and any deadlines. Clear documents help avoid confusion and make sure everyone understands what they’re getting.

Communicate vesting timelines to new hires

Vesting can feel confusing to people who haven't dealt with equity before. That’s why it’s important to explain it in simple, plain language. New hires should understand:

• What vesting is
• How their vesting schedule works
• What part of their equity do they own now
• What happens if they leave the company

How does vesting take place when an employee leaves the company?

What happens to vesting when someone leaves depends on how far along they are in their vesting schedule and on their role in the company. Here’s how the most common situations work.

Before the cliff period 

If someone leaves before the cliff, none of their equity vests. Because the cliff is the point where vesting actually starts, leaving early means they walk away with zero ownership. All of their granted shares or options return to the company or the option pool.

After the cliff period 

Leaving after the cliff works differently. Once the cliff is passed, part of the equity has already vested. That vested portion belongs to the employee, and they get to keep it.

However, anything unvested stops vesting the day they leave and usually goes back to the company. If they have stock options, they often get a short window (usually 90 days) to exercise the vested part, depending on the plan.

Founder departing

When a founder leaves, the stakes are much higher. If the founder has a reverse vesting agreement, the company can buy back their unvested shares. How many they keep depends on how much has vested at the time they leave.

If there were no founder vesting in place, things would get messy fast. A founder may leave early but still retain a large part in the company, which can scare off investors and make hiring harder. This is one of the biggest reasons founder vesting exists in the first place.

Key executives departing

When a key executive leaves, such as a CTO or COO, their equity is treated the same as that of other employees unless they negotiated special terms.

Some executives have acceleration in their contracts, meaning part of their unvested equity vests faster if they are let go or if the company is acquired. Others follow the standard vesting plan. Either way, vested equity is theirs, and unvested equity stops vesting immediately.

How does vesting affect a cap table?

Vesting ensures people only retain the equity they’ve earned. If someone leaves early, they lose their unvested shares, which are returned to the company. This prevents the cap table from being filled with people who are no longer involved but still own big chunks of the business.

Employee option pools are used to give equity to new and existing team members. Vesting helps keep these pools healthy. When someone leaves before vesting is complete, their unvested shares are returned to the pool, freeing up equity for future hires. This helps the company grow without constantly increasing the pool, thereby avoiding extra dilution.

Vesting also affects how much everyone gets diluted during new funding rounds.
It helps because:

• Unvested shares that return to the pool reduce the need to issue more shares
• A clear vesting structure makes fundraising smoother
• Investors may ask for a larger option pool before they invest, and vesting affects how big that pool needs to be
• Founders who agree to refresh or extend their vesting can show commitment and reduce investor concerns

On the other side, investors always look at how much equity is vested versus unvested. They want to know:

• Whether founders are still committed
• If the team has enough unvested equity left to stay motivated
• Whether someone who left still owns too much
• How stable the cap table is

Frequently asked questions about vesting

1. What happens to vesting if the company shuts down?
If the company shuts down, unvested equity is usually lost, and vested shares are typically worthless unless there’s remaining value to distribute.

2. Do vested shares automatically become liquid in an acquisition?
No. Vested shares don’t automatically turn into cash; the outcome depends on the terms of the acquisition deal.

3. How does vesting impact participation in secondary share sales?
Only vested shares can be sold in a secondary sale, since unvested shares are still tied to your vesting schedule.

4. Can unvested shares convert to cash during an exit?
Unvested shares usually don’t turn into cash unless the exit terms specifically include an acceleration or a negotiated payout.

5. Can vesting continue if a founder switches to a part-time or advisory role?
Sometimes, continued vesting depends on what the board or the founder agreement allows for in the new role.

6. Does vesting impact how much equity a founder needs to keep to pass investor due diligence?
Yes, investors expect founders to have enough unvested equity to show long-term commitment.

7. Can vesting continue during parental leave or extended medical leave?
Often it does, but it depends on the company’s equity plan and local employment laws.

8. How does vesting operate during a company pivot or change in business model?
Vesting usually continues unchanged, unless the company restructures roles or renegotiates agreements.

9. Can vesting be paused, restarted, or frozen under special circumstances?
It can, but only if all parties agree and new terms are formally updated in the equity documents.

10. Should early employees and late-stage employees have different vesting structures?
Yes, early employees often receive more equity or different terms because they take on more risk than late-stage hires.
