Validate your startup idea before you build it.

Enter to validate. Shift + Enter for a new line.

See what changed the verdict.

Every recommendation separates verified facts, supported inferences, and missing evidence so you can challenge the result.

Illustrative verdict

Revise before building

Revise

The problem is credible, but the audience is too broad and pricing evidence is missing.

Verified factTeams already pay for fragmented alternatives.
Supported inferenceA narrower founder segment has clearer urgency.
Missing evidenceWillingness to pay still needs a live test.

Next experiment

Run five pricing conversations with the narrowest founder segment.

Claims stay linked to inspectable sources.

Evidence should change the decision.

RoastIdea turns market research into a judgment you can inspect, challenge, and improve.
