Founders typically encounter vesting as a term sheet line item from a VC. The pitch goes: investors require it to protect their investment. That’s true but incomplete. The deeper, less polite reason vesting exists is that cofounders — even ones who genuinely like each other on day one — need a structural backstop against the cofounder who quits, gets fired, or checks out while still holding 40 percent of the company.
The scenario every cap table wants to forget
Picture two cofounders splitting equity 50/50, no vesting, no investors yet. Six months in, one of them takes a corporate job, drifts away, stops responding to Slack. The remaining cofounder builds the product, lands customers, raises a seed round. Three years later, the company is worth $20 million. The departed cofounder still owns half. There’s no clean legal mechanism to claw back the equity, because nobody put one in writing. The remaining founder either buys them out at a price that reflects work they didn’t do, dilutes themselves heavily, or watches a passive shareholder veto the next round. This isn’t a hypothetical — every startup lawyer has seen variations of it. Vesting solves it before it happens.
Why “investor pressure” is the wrong frame
Founders often resist vesting as a sign of distrust, framing it as a hoop investors make them jump through. That framing protects the social dynamic but obscures the function. A standard four-year vest with a one-year cliff means that if a cofounder leaves at month ten, they walk with zero equity, and the company recaptures the shares. Leaving at year two means they keep half. The schedule aligns ownership with contribution over time. Crucially, this benefits the cofounder who stays at least as much as it benefits any future investor. Many of the worst founder disputes happen pre-investment, between people who agreed in good faith but never wrote down what would happen if circumstances changed. Vesting writes it down.
How to set it up before it’s painful
The cleanest approach is to put vesting in place at incorporation, with cofounders co-signing as a mutual protection rather than as one party imposing terms. A four-year vest with a one-year cliff is the market standard for a reason — it gives enough time to assess commitment without punishing someone who hits a real life event in year three. Acceleration clauses (single-trigger on acquisition, double-trigger on acquisition plus termination) deserve thought but shouldn’t dominate the discussion. The founder who insists on no vesting because “we trust each other” is the founder you should worry about most; trust isn’t a substitute for documentation. Talk to a startup attorney before the conversation gets emotionally loaded, not after.
The bottom line
Vesting isn’t a concession to investors. It’s a peace treaty between cofounders signed while everyone is still friends. The founders who skip it almost always regret it, because the cost of unwinding ownership later vastly exceeds the discomfort of agreeing to terms now. Set it up early, make it mutual, and move on.
