Riskiest assumptions list before the first interview
Founders who start interviewing without written assumptions tend to hear whatever confirms the idea. Listing the eight to twelve beliefs the business depends on, and ranking them by how fatal it would be if each were wrong, tells you what the first twenty conversations must actually test.
First tasks
- Write every belief the business depends on as a one-line statement
- Score each assumption for impact if wrong and for evidence so far
- Pick the three riskiest assumptions to test first
- Share the ranked list with your co-founder and ask for one challenge each
