Quick Answer
A legal agreement between co-founders establishing equity splits, roles, vesting, IP ownership, and departure terms.
A co-founder agreement formalizes the relationship between startup co-founders, covering equity allocation, vesting schedules, roles and responsibilities, decision-making authority, IP assignment, non-compete provisions, and terms for founder departure. While often overlooked in the excitement of starting a company, the absence of a co-founder agreement is a major red flag for investors and a common source of startup-destroying disputes.
In Practice
Two co-founders sign an agreement: 60/40 equity split (reflecting different commitment levels), 4-year vesting with 1-year cliff, the CEO has final say on business decisions, the CTO on technical decisions, and departing founders must sell unvested shares back at cost.
Why It Matters
Co-founder disputes are among the top reasons startups fail. A clear agreement prevents misunderstandings and provides a framework for resolving disagreements before they become existential.
VC Beast Take
The biggest mistake is waiting until you need investment to create a co-founder agreement. VCs will demand to see it, and any gaps or conflicts become major red flags. The hardest part isn't equity splits — it's defining roles and decision-making authority. Most co-founder breakups happen because responsibilities weren't clearly delineated from day one, not because of equity disputes.
