Build evidence, not assumptions.
Live · private workspace
Problem
Early-stage teams talk about “validation” as if it were one thing. In practice they mix opinions, anecdotes and real evidence. Decisions get made on whichever was said most confidently.
Built
A venture workspace following the chain opportunity → hypothesis → assumptions → experiments → evidence → decisions → next action. Every validation level is backed by supporting and contradicting evidence and a written rationale.
