I got lucky: I built with people I'd known for years
Why I now tell founders to choose a co-founder like a decade-long marriage, not a hire.

Operating a startup is a longer journey than you'd expect – and so is a co-founder relationship.
People obsess over the idea, the market, the timing. Yet the thing that actually carries you through the years is the one we question the least: who you choose to do it with.
More than a shared vision
A co-founder relationship needs constant alignment, a shared vision and a culture you build together. But far more than that, it needs the daily grind of deciding together: the small calls, the big ones, and the economic scenarios that could undo what you spent years building.
What got us through
I got lucky. Some of my co-founders I had known since school. I could trust them deeply, because I already knew who they were under pressure.
We didn't always agree – no real partnership does. But what I value now more than ever is that we always respected each other, we always picked up the phone, and we always had a joke ready. That is what gets you through the worst weeks. Not the cap table, not the strategy: the people.
What I tell founders today
Choose your co-founders like a decade-long partnership, not a hire.
Who did you choose to build with – and would you choose them again?
