The kindness author who built the most adversarial startup feedback tool on the internet.

Why it was built

Greg Atkinson built PivotProof after learning a familiar founder lesson the expensive way. Advisors, cohort mates, and customer conversations all found the original idea interesting. The problem surfaced only after months of building.

PivotProof moves the hostile room to the beginning, before politeness and sunk cost make the decision harder.

What it does

Five hostile expert personas read one startup idea and issue a verdict. Their combined read produces a Pivot Score, red flags, kill criteria, pivot suggestions, and experiments worth running next.
