Build fast. Prove faster.
A first-wallet reality check for builders using new coding tools. Score the evidence behind your idea instead of treating a market headline or a polished prototype as demand.
Evidence scores
Use 0 for no evidence and 5 for strong evidence. These are your assumptions, not market facts.
Run the check to see your weakest proof.
Assessment: remove willingness-to-pay evidence and rerun. The weakest link should become visible.
Values persist locally.
Correction: fast building is not product-market fit, and a large tooling-market claim does not predict your first customer. A first wallet still needs a specific buyer, a painful problem, a reachable person, and a concrete ask.
