The Founder Prenup
Overview
A set of critical discussion topics for co-founders to align on before starting a company (or to revisit periodically). Designed to prevent the 65% of startup failures caused by co-founder conflict.
Core principle: Assume nothing. If you act based on your values and they act based on theirs, you'll think they're acting strangely—but they're just being themselves.

Common Mistakes
- Assuming alignment because you're friends
- Avoiding the conversation because it feels awkward
- Not revisiting as the company evolves
Real-World Example
Two co-founders realized too late: one wanted a massive venture outcome, the other wanted a small shop where they knew everyone's name. The painful split could have been avoided with this conversation upfront.
