Most startup feedback is useless.
Your advisors are too polite. Your co-founder is too invested. Your customers say they'd use it — until it's time to pay. You burn six months and $30,000 before you find out the idea had a kill-level flaw that a hostile expert would have spotted in the first minute.
PivotProof fixes this.
MEET THE 5
Five hostile experts. One idea. Sixty seconds.
Marcus Chen
The skeptical VC
Finds the market-size problem you're hiding from yourself. He's seen this pitch before and passed.
Priya Anand
The jaded customer
Already has a workaround and isn't looking to switch. Names three tools she already uses that solve 80% of your problem for free.
Daniel Reeves
The competitor
Calculates exactly which quarter he ships your product as a checkbox in his next release.
Dr. Lena Voss
The domain expert
Names the non-obvious gotcha that turns your 3-month MVP into a 3-year build.
The Devil's Advocate
No name. No title.
Just the extinction scenario, narrated start to finish, complete with the news headline.
What you actually get.
- A Pivot Score from 0–100 — below 35 means stop, above 70 means run
- Each panelist's verdict + a direct quote you can screenshot
- Kill criteria: specific, dated, binary metrics that'll tell you when to stop — written before sunk-cost fallacy kicks in
- Concrete experiments to run before writing a line of code
NOT ANOTHER
- Not a template. Not a canvas.
- Not another Notion doc.
- Not asking ChatGPT to be “more critical” — it won't be. It's trained to be agreeable.
- PivotProof's personas are built to find the kill, not to validate the hypothesis.

Short description (260 chars)
PivotProof simulates five hostile expert personas — a skeptical VC, a jaded customer, a competitor, a domain expert, and a devil's advocate — and issues a Pivot Score (0–100) on your startup idea in under 60 seconds. No fake quotes. No soft feedback. Just the truth.
First comment (post yourself)
Hey PH — Greg here, founder of PivotProof.
I built this after watching myself and a dozen other founders spend real time and money on ideas that had obvious kill-level flaws. Not obvious in hindsight — obvious the moment a hostile expert looked at them. The problem: we never got that feedback. Advisors are polite. Friends are supportive. Customer interviews are biased. So we built anyway.
PivotProof runs your idea through five hostile expert lenses — a skeptical VC, a jaded customer, a competitor, a domain expert, and a devil's advocate — and tells you what your network won't.

Happy to answer anything about how the personas work, how the Pivot Score is calculated, or what the kill criteria actually say. Brutal feedback welcome — I'd be a hypocrite to avoid it.
Maker bio
Greg Atkinson — built PivotProof because advisors are too polite and prototypes are too expensive. The gap between “this sounds interesting” and “no one will pay for this” costs founders a year of their life. I wanted to close that gap to 60 seconds.
The panel doesn't care about your feelings.
And that's the point. First report is free. No card required.
