How to Write a Great AI Prompt to Validate a Business Idea
Most people ask AI to "Is my business idea good?"—and wonder why the output is mediocre. Here's how to write a prompt that actually gets you what you want on the first try.
"Is my business idea good?"
Too vague—AI has to guess what you want
"Act as a critical but fair startup advisor. Evaluate this business idea: [idea]. Cover: (1) market size and whether it's real, (2) top 3 risks and how fatal each one is, (3) existing competitors I may have missed, (4) one version of this idea that would be stronger. Be direct — do not pad with encouragement."
Specific, clear, ready to use
What makes the strong prompt better?
Persona of 'critical but fair' prevents sycophantic validation
Four-part structure ensures a comprehensive view not just surface praise
Explicitly bans padding so the output stays honest and useful
