Technical founders obsess over latency and reliability, then sign equity paperwork like its boilerplate. Thats backwards: your cap table will outlast most product decisions, and its harder to refactor.
Splits: Pay for the future, not the past
A fair founder split prices future work and risk. Shipping an MVP is real effort, but its not the same as carrying a company through hiring, fundraising, and years of execution.
Use inputs that actually predict future contribution:
Domain depth that reduces go-to-market risk, real time commitment (not nights and weekends promises), cash put in, scarce skills that cant be hired easily, and relationships that reliably open doors (customers, partners, investors).
Vesting isnt optionalits a seatbelt
All founder equity should vest. Not because anyone expects betrayal, but because startups change: co-founders burn out, priorities shift, life happens. Unvested shares are the only clean way to handle a clean break.
The default youll see in the U.S. is a multi-year schedule with a cliff. Treat that as a starting point, not a moral law. What matters is the principle: equity is earned by staying and contributing, not by showing up on day one.
If acquisition is a plausible path, learn the difference between single-trigger and double-trigger acceleration. Single-trigger can pay out just because a deal closes; double-trigger ties acceleration to both a change of control and a termination or role change. That second condition is there to stop founders from getting cleaned out of their jobs while their equity stays locked.
Option pools: where founder ownership quietly disappears
Option pools are usually created before a financing closes, which means the dilution lands on the existing holders (often the founders), not the new investor. Thats common practice, and its still worth pushing back on when the pool size is pure guesswork.
Dont agree to a pool because it sounds standard. Tie it to a hiring plan you can defend: roles, seniority, and the time window you expect to cover before the next round forces a refresh.
| Stage | Founders | Pool | Investors |
|---|---|---|---|
| Formation | All ownership | None | None |
| After a seed round | Reduced materially | Created or expanded | Meaningful new stake |
| After Series A | Often no longer a majority | Ongoing top-ups | Larger combined ownership |
How to keep your cap table from turning into a surprise
Equity problems usually arent caused by bad intentions. They come from founders who never model scenarios and only discover the outcome when a term sheet shows up.
Do these things early, and repeat them before any major change:
Get a startup attorney. Not a generalist. You want someone who sees venture documents every week and will tell you what youre actually signing.
Read the real control points. Vesting terms, repurchase rights, option pool language, acceleration, and protective provisions matter more than the headline valuation.
Model dilution before you negotiate. Run your cap table with pool changes, new rounds, and refresh scenarios. If you cant explain the numbers to your co-founder in five minutes, youre not ready to sign.
Keep a paper trail. Signed grants, board approvals, exercises, and vesting schedules should be easy to find. Future diligence will punish you for well track it later.
Next action: open a spreadsheet and write down every class of shares, every grant, and every vesting schedule you think exists. Then verify each one against signed documents. If you cant prove it, assume its wrong.
