Assumption Mapper

Every venture runs on untested beliefs. Assumption Mapper makes those beliefs visible and testable.

Capture assumptions in 2 seconds via Cmd+K. The Focus View surfaces your top 5 riskiest untested beliefs every morning — ranked by importance and evidence gap. Log evidence from interviews, experiments, and data pulls, then make explicit decisions: validated, invalidated, or need more.

The decision log becomes your venture's institutional memory — a record of what you believed, what you learned, and what you decided. No more "we validated that" without receipts.
