Cofounder Equity, Three Years Later
Sixty-forty in year one, each cofounder doing half the work. The forty-percent cofounder noticed in year three, and the relationship never recovered.
Two people start a company. One had the idea a few months earlier, so the equity lands at 60/40. Both agree in the moment. Neither runs the math past the split itself. Three years later, one of them runs it.
By year three, both founders had worked equivalent hours for thirty-six months. Both had taken comparable risk. Day to day, you couldn't tell their contributions apart. The twenty-point gap, compounded against a rising valuation, had become a real dollar difference. The smaller-share cofounder began to resent it. The larger-share founder felt the resentment and got defensive. By year four they were barely speaking, and the company was managing around a partnership that had gone quietly hostile.
The conversation that would have prevented this was the equity conversation at founding. It got deferred because both were busy starting the company and the split felt procedural. What emerged reflected timing, who had the idea first, who joined later, not contribution over the long run. By the time the long run arrived, the split encoded an early circumstance that no longer meant anything operationally. It's the same conversation founders keep postponing until it's expensive.
This is one of the most consistent failures in early cofounder relationships. The equity call gets made under time pressure, with little information about how the relationship will develop, and then locked in for the life of the company. Most splits at founding are wrong in some direction. The wrongness shows up two to four years later, once the cofounders have worked together long enough to see what each brought.
The simplest guard is an equal split at founding. Equal is rarely exactly right, but it's rarely catastrophically wrong, and it avoids the slow discovery that one cofounder has been the smaller share of an equal contribution. An equal split also forces the pair to be honest about whether they're cofounders at all. If one party won't accept equal, they're signaling, usually accurately, that they don't think the partnership is equal.
Unequal splits are appropriate in specific cases that need explicit agreement. Genuinely unequal time commitments. Genuinely unequal roles. Unequal financial investment. In each, the split can be justified, and the justification should be written down in a form both cofounders can reread years later and still agree with. The same discipline applies when you hand someone a board seat: cheap to give away in the moment, costly to claw back.
The conversation that produces the agreement is uncomfortable and cheap. It happens at founding, while the equity is being assigned. Both cofounders describe their expected contribution over the next four years. Both agree on what the split should be against it.
Re-equalizing later is possible and rarely works. The cofounder with more equity has to give some back. Most can't bring themselves to, even when they think the original split was wrong.
Equalize at founding. Or have the explicit conversation about why you aren't.
