How Founders Set Up a Founder Vesting Schedule

Few founders enjoy the idea of putting their own shares on a vesting schedule. It can feel like signing a contract against yourself. In practice, a well designed founder vesting arrangement is one of the cheapest forms of insurance a young company can buy.

Vesting means a founder earns full ownership of their shares gradually over time. If a co-founder leaves early, the company can typically buy back the unvested portion, usually at the original low price, so the equity stays with the people still building the business. This guide explains how it works and what to decide before anyone signs.

Why Vesting Matters

Imagine three founders split the company equally. Six months later, one walks away. Without vesting, that person keeps a third of the company forever, while the remaining two do all the work. That imbalance can make the company very hard to finance, because new investors are reluctant to back a business where a large stake belongs to someone no longer involved.

Vesting solves the problem before it arises. It also signals maturity. Many institutional investors expect founder shares to be subject to vesting, and some will ask for it as a condition of investing if it is not already in place.

The Common Structure

A widely used pattern in the United States startup market is four years of vesting with a one year cliff. Under that structure, nothing vests during the first twelve months. At the first anniversary, a quarter of the shares vest at once, and the rest typically vest in equal monthly instalments over the following three years.

This is a convention, not a rule. Some founders give credit for time already spent on the company before incorporation, so that part of the stake is vested from day one. Others choose shorter or longer periods. What matters is that all co-founders understand the terms and that they are written into the company's legal documents rather than agreed on a handshake.

Key Choices to Make

The Cliff

The cliff protects the company from a very early departure. Founders who have worked together for years sometimes reduce or waive it, while new teams often keep it as a trial period.

Acceleration

Acceleration allows some or all unvested shares to vest early when a specified event happens. Single trigger acceleration usually refers to vesting on a sale of the company. Double trigger acceleration typically requires both a sale and the founder's termination without cause. Acquirers often prefer double trigger terms because they want key people to stay after a deal.

Leaver Terms

Decide what happens to vested and unvested shares if a founder resigns, is removed, or leaves through illness. Many companies distinguish between so called good leavers and bad leavers, though the definitions vary and should be drafted carefully by a lawyer.

Tax and Paperwork

In the United States, founders who receive shares subject to vesting often consider filing a Section 83(b) election with the Internal Revenue Service. The deadline is strict, generally 30 days from the date the shares are issued, and missing it can create significant tax consequences later. Rules differ in other countries, so founders outside the US should take local advice.

The vesting terms themselves usually sit in a stock purchase or restricted stock agreement, supported by board approval. Keep signed copies, track each founder's vesting dates and make sure the company's capitalisation table reflects what has and has not vested.

Talk About It Early

The hardest part of founder vesting is the conversation, not the paperwork. Raise it while everyone is optimistic and committed, not when tension has already appeared. Frame it as protection for each founder against the others leaving, rather than as a test of loyalty.

Founders who settle vesting early spend less time later arguing about fairness and more time building. It is a small amount of effort now that can save a company when circumstances change. As always, take advice from a qualified startup lawyer and tax adviser before finalising any terms.
