“At Polyvore, Pasha and I split equity in a way that reflected who was taking the company forward, not who had the original idea. I’d rather see founders have one hard conversation now than a dozen resentful ones later.”

“The cleanest split is rarely equal. I have seen 50/50 founder agreements blow up when one person carries the company and the other holds half the cap table, so I would rather see equity matched to contribution, risk, and role, with a four-year vest and a one-year cliff for both of you.”

“I see founders split equity equally because it feels fair on day one, then two years later one person is carrying the company and the other is a ghost on the cap table. My first company ended up 55/45 on a one-page founders agreement, and when we sold six years later we just looked at the paper. No fight.”

“I’ve seen too many teams lock in a 50/50 split in the first month, then watch resentment compound as roles and commitment shift. At Appex and the companies after, I learned that the split matters less than the conversation: founders need to align on what they actually value before they divide anything.”

“I think the biggest early decision is whether you need an equal co-founder or a late co-founder. Startups are authoritative: one person makes the call, and 50/50 often creates tension when the load isn't equal. I'd rather see 70/30 or 60/40, with a steep step down for someone who joins later.”

“I see too many founders treat equity like a math problem and skip the conversation underneath it: who actually makes the final call when you disagree, and what happens if one of you needs to leave. I wrote a co-founder prenup for exactly this, because a startup marriage needs the hard terms spelled out before the romance wears off.”

“Equity splits are where founders pretend they're being fair while optimizing for the wrong thing. I've watched too many cap tables rot because someone left at year two with a quarter of the company locked up.”

“I’ve seen resentment over a 5% difference cost a company 10x that in lost energy and silent sabotage. Split on current sacrifice and future contribution, not friendship, and vest everything over four years with a one-year cliff. Build the cap table for the day you have $1k in the bank and six months of missed salaries, not the fantasy exit.”

“I tell founders to get as far as they can alone, because a cofounder you bring in after revenue or a seed round will take 5% with vesting instead of half your company. I have watched too many startups die because someone handed 50% to a stranger who looked good on paper and then stopped performing.”
