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.
See what happens when five hostile experts read your pitch.
Six anonymized reports from real founders. Some survived. Most didn't. Every verdict was generated by the same panel that will read yours.
A generic real estate marketplace with zero differentiation entering a graveyard of billion-dollar corpses and entrenched monopolies.
Vague operations promise in saturated market with entrenched giants, no differentiation, capped TAM, and zero demonstrated moat.
Undefensible margin structure meeting microscopic TAM in the most expensive real estate market, competing against established chains and customers' own kitchens.
A feature masquerading as a company in a saturated market with no moat, regulatory landmines, and defensibility theater.
Not paying anyone for fake quotes.
Every other SaaS landing page has three smiling headshots giving polite quotes. We'd rather ship real receipts than manufactured ones.
“Read the actual verdicts on the Hall of Brutal Verdicts. Every score you see there is a real founder who submitted a real idea.”
“Or try it on your own idea, right now, for free. If it's honest, useful, and doesn't flatter you — that's the whole product.”
“Ran PivotProof? Loved it or loathed it? Every user is prompted to leave a receipt right after their report — we publish the approved ones here.”
