Know what to test
before you build.

We prioritize one unresolved condition: founder fit, an essential delivery blocker, access to buyers, evidence of a real problem, a costly current response, paid commitment, delivery, then the smallest repeatable build. No score is calculated. Your written context is inserted into the plan; it is not interpreted by AI.

The result is a starting test, not proof of demand or a complete business assessment. Choose your own time and spending limit. Record what happens and reassess; a few interviews or one paid pilot cannot establish a viable company.

The test structure draws on Strategyzer’s Test Card ↗ and NSF I-Corps customer discovery ↗. The priority rules are One Question’s working judgment.
