Your idea will be torn apart by five experts who think it's bad.
PivotProof simulates a hostile VC, a skeptical customer, a competitor, a domain expert, and the devil's advocate — then issues a quantitative Pivot Score. Find out if your idea is worth a year of your life. In 60 seconds.
Submit your idea.
We make it defend itself.
Title. One paragraph. Target customer. Stage. Optional URL. That's all our panel needs to begin. No fluff. No founder narrative. Just the idea, naked.
5 hostile personas
Each one independently briefs against you. No softening. No “but the upside is…”
Kill criteria
The exact conditions under which you should walk away — written before you start.
Pivot Score 0–100
A single number, weighted by the panel's verdicts. Below 35 means stop. Above 70 means run. Everything between is the work.
Concrete experiments to validate before writing a single line of code.
The panel doesn't care about your feelings.
A few real lines from past sessions. Names changed. Pain preserved.
Founders who took the punch.
Identifying details removed by request — these are real reactions from early sessions.
“Got a 14/100. Saved me eight months of building the wrong thing. I owe these guys lunch.”
“The hostile VC persona caught the same TAM hole my actual advisor missed for two months.”
“Brutal in the best way. Every kill criterion was something I'd been quietly worrying about.”
