Copy/paste template
Prompt
Stress-test this startup idea. Identify the riskiest assumption, assumption mapping, customer segment, problem-solution fit, demand signal, willingness to pay, fake door test, concierge MVP option, and evidence standard. Return a stage-gate validation plan with the first three tests, pass/fail thresholds, expected failure modes, and what we should stop doing if evidence is weak.
Terms this prompt forces into the work
Riskiest assumption
Finds the belief that can kill the idea fastest.
Assumption mapping

Problem-solution fit
Separates pain evidence from solution enthusiasm.
Demand signal
Looks for behavior, not compliments.
Fake door test
Measures interest before full build.
Willingness to pay
Tests if the pain is worth money, time, or internal effort.
