Get Your Founder Equity Split in Writing — Early

Co-founders almost never fight about the idea. They fight about who owns what, once the idea starts working. An equity split that felt fair in month one — when nobody had a salary and everyone was guessing — rarely holds up once one founder has put in eighteen months and another has put in three. The split itself isn't usually the problem. The absence of a written agreement is.

"We'll figure it out later" is a decision, not a delay

Every founding team that skips the paperwork tells themselves they're deferring the decision. They aren't. They're defaulting to whatever a court or a frustrated co-founder decides equity should look like after the relationship has already soured — which is the most expensive way to resolve a question that was cheap to settle up front.

Vesting protects the team, not just the company

A standard four-year vesting schedule with a one-year cliff isn't there to punish anyone. It's there so that if a co-founder leaves after four months, they leave with four months of equity — not a permanent, unearned stake in something the remaining founders spend years building. Vesting is one of the few legal protections that genuinely benefits everyone at the table, including the person it restricts.

Unequal contribution deserves an unequal split

Splitting equity evenly feels like the fair, friendly move. It's often the wrong one. If one founder is full-time and another is part-time, if one is funding the company and another isn't, an even split quietly under-rewards the person doing more. Naming that imbalance early, in writing, prevents it from curdling into resentment later.

What this actually requires

A founders' agreement doesn't need to be complicated. At minimum it should cover the equity split itself, a vesting schedule, what happens if someone leaves, and how future decisions — adding a co-founder, raising capital, issuing new equity — get made. The document is short. The conversation it forces you to have early is the valuable part.
