Maintaining the Co-founder Relationship

Based on remarks by Brian Chesky, co-founder of Airbnb, at Stanford GSB (Feb 2023).

The one rule

Airbnb's founding team had a single governing rule for how they handled disagreement:

"Winning an argument was never more important than preserving the relationship."

The logic is simple: you're going to debate a hundred thousand things over the life of a company. No single argument can be the deciding one. What has to exist beneath every disagreement is a larger shared identity — Chesky's word for it is band. You're not two individuals trying to win; you're a unit trying to build something together.

Treat it like exercise

Chesky's framing for the work involved: a co-founder relationship is like physical fitness. If you stop exercising, you get out of shape. It requires ongoing effort, not a one-off investment.

In 2009 — Airbnb's early days — the founders committed to a fixed ritual: every Sunday, they would meet, regardless of how busy things got. Chesky says they still keep those calls to this day.

The specific mechanism matters less than the commitment behind it. A recurring touchpoint forces contact even when things are going well — which is exactly when founders tend to skip it.

What sustains it

Chesky's summary of what the relationship actually runs on:

• Constant contact and connection — you can't maintain closeness at a distance
• A deep sense of respect — for each other as people, not just as functional contributors
• Humility and gratitude — internalising that you are only there because of them
• No desire to win alone — "if I win alone, I'm not going very far"

The last point is the most counterintuitive for competitive founders. Letting go of the need to be right in any given moment is not weakness — it's what makes a founding team durable over years.
