The equity split between cofounders is one of the most consequential decisions a founding team makes, and one of the least discussed before it becomes an emergency. Most teams default to equal splits for simplicity, or negotiate percentages based on gut feel, then discover the problems two or three years later when someone's effort has diverged from their ownership.

Ideas are cheap; execution is what creates value. Giving extra equity to the "idea person" who may not be the hardest worker sets a bad precedent. Equity should track the actual risk and work each cofounder is taking on, not who wrote the first pitch deck. If the idea person is not doing more to build the company, the split should reflect that honestly.
Vesting is not about distrust — it's about aligning incentives over time. A cofounder who leaves after six months should not keep the same equity as one who stays for four years. The standard four-year vest with a one-year cliff is an industry norm because it works: it rewards staying, discourages early exits, and gives the company a mechanism to recover equity from leavers. Skipping vesting consistently causes serious damage later.
"We trust each other" is not a structure
Vesting isn't about distrust — it's about time. Without it, a cofounder who leaves after six months keeps the same equity as one who stays four years, and the company has no mechanism to recover it.
Early-stage founding teams often split 100% of the company between themselves, leaving nothing for employees, advisors, or investors. Then the first meaningful hire asks for equity and suddenly someone has to give up their personal stake. Build the reserved pool into the cap table from the start — typically 10-20% — so future dilution is structured and expected rather than fought over. Equafy treats the reserved pool as a first-class cap table element, not an afterthought.
Equafy is built around the principle that equity should be transparent, tracked, and updatable. Fixed allocations for cofounders who want certainty sit alongside a dynamic pool that accumulates based on ongoing contributions. When you issue new shares — for an employee, an advisor, or a round — the system shows every member's dilution in real time before you commit.
| Mistake | What it causes | The fix |
|---|---|---|
| Splitting on the idea, not execution | Equity that tracks who pitched first, not who takes the risk | Split on actual contribution |
| Skipping vesting | A six-month cofounder keeps a four-year stake | Four-year vest with a one-year cliff |
| Forgetting the reserved pool | Founders fund the first key hire from their personal stakes | Carve out 10-20% before negotiating |
Equal splits (50/50 for two founders, 33/33/33 for three) are most common but not always the fairest. They work best when all cofounders have equivalent risk, commitment, and skills — which is rare.
Technically yes, but it requires legal documentation and unanimous consent. It's far easier to build in a dynamic model from the start that adjusts automatically, rather than renegotiating fixed percentages later.
Not necessarily. The CEO title doesn't guarantee the highest contribution. Equity should follow value creation, not hierarchy — especially in the early stage before formal management structures matter.
Equafy lets you set fixed equity for each cofounder, run a dynamic equity pool for contribution-based tracking, or mix both. All changes are logged in a full audit trail.
Equafy gives your founding team a single source of truth for equity — with fixed allocations, dynamic tracking, and full audit history from day one.
