Founders' Agreement
Also called Founder Agreement
A contract among co-founders setting out equity splits, roles, decision-making, vesting, and what happens if someone leaves. The prenup of a startup.
Why it matters
Founder disputes are one of the top killers of startups, and a clear agreement made early, while everyone is friendly, prevents ugly fights later. Skipping it to avoid an awkward conversation is a classic, costly mistake.
For example
Before writing code, three co-founders sign an agreement setting equity at 40-40-20, four-year vesting, and what happens if one leaves early.
