The co-founder state-of-the-union

The number-one failure cause for startups in the first eighteen to twenty-four months, per a number of VC data cuts (CB Insights, Concept Ventures), is not product. It's not market. It's that the co-founders fall out.

When I say this to founders, most nod politely and think 'that won't be us.' It will be you, probably, if you don't do the maintenance. Equity is locked, the cliff just vested, the mortgage is now co-signed with the relationship, and nobody has the language or the forum to say the thing that would have saved it twelve months earlier.

Why it happens in year two specifically

Year one is survival — fundraise, first hire, first customer. The work is so crushing that nobody has the cognitive room to notice the relationship is drifting. Year two is when the first real stress tests land: a bad hire you both kind of knew was bad; a term sheet that revealed different risk appetites; a month where revenue went backwards. Those tests don't break strong relationships. They break weak ones that nobody audited.

The quarterly state-of-the-union

Once a quarter, ninety minutes, no laptops, outside the office. Same five prompts every time. You don't need a coach. You need the prompts and the discipline to sit with the answers.

• What's the one decision we made this quarter that I'd make differently now — and what does that tell us about how we decide?
• Who carried more than their share this quarter, and who carried less?
• Name one thing the other person did this quarter that you haven't acknowledged yet. Say it now.
• Name one thing the other person did this quarter that's bothering you, that you haven't raised. Raise it now.
• If we knew right now that we'd have to separate within twelve months, what would we want to have said, done, or documented before that happened?

The last one is the hardest and the most valuable. It forces you to treat the partnership as a thing that exists on a clock, not as a given. Most co-founder pairs who make it through year three say the same thing: they started running this conversation, or one like it, before they thought they needed to.

What to do if it's already broken

If the conversation has been deferred for eighteen months, don't run the prompts cold. Get a third party — a board member, a trusted advisor, a therapist who works with founders. A broken partnership in a funded company is a workout session, not a workshop. Treat it with the severity of a financial restructure, because that's what it is.

A co-founder relationship isn't a vow, it's a contract. Contracts get renegotiated. The ones that don't get renegotiated get broken.
