Frequently asked questions
How does Preuve AI score business ideas?
Ten AI agents scan 60+ live sources in parallel across market size, demand signals, and economics, cross-validating evidence to calculate a 0-100 score.
Are submitted business ideas kept confidential?
Yes. Submissions are encrypted in transit and at rest, processed strictly by AI, and never used to train models or reviewed by humans.
What does a viability score below 70 indicate?
A low score is a direction rather than a verdict, signaling when a market is crowded, timing is off, or targeting is too broad, with suggested pivots.
What is Preuve Sentinel?
Sentinel is an alert service included for 3 months with Founder Reports that reruns market analyses monthly to track changes.
