Propelo. Four months of building. Zero paying users. Not because the idea was wrong — because there was no one to challenge it, validate it, or push back. Built by a solo founder at 17, for every founder figuring this out alone.
Built for the first idea. The first product.
The first time doing this alone.
It does what the others don't.
Four sources. One score. Three minutes.
Prova scans X, Reddit, App Store reviews, and your named competitor in parallel, then converges it into one number.
Permanent memory
She never forgets a detail about your business.
She remembers the pricing test that flopped in April.
She remembers the commitment you made in week one — and whether you kept it.
She remembers the pivot you talked yourself out of at 2am.
She remembers the competitor you said didn't matter.
The loop.
Deep Dive
Scores your idea against live market data.
Memory
Stores the score, the pivots, the commitments.
Commitment Gate
Blocks the next dive until you act.
Prova
Brings it all up next session — unprompted.
Then it starts over. Same idea, sharper every time.
ChatGPT can't see X. Claude can't see Reddit.
Prova sees both.
Live X search, every session.
Live Reddit search, refreshed every session.
How she thinks
Deep Dive
Scores your idea against live Reddit, X, and web data in under 3 minutes.
Score Ladder
Every score is on record. Watch it move, or don't.
Bull / bear
Prova argues both sides before she gives you the call.
Archetype + percentile
Ranked against every idea Prova has scored, not against nothing.
Pick one to start

Commitment Gate

Scoring anchor
Your first score stays visible so drift can't hide.
Morning Brief
What changed in your market overnight, before you open the app.
“This gives a different angle that a back and forth with Claude or GPT chat can't achieve.”
Ian Madez, @spacethaMenace on X“I like the tone Prova has, it helps you move... I went out and did exactly what it suggested — something I'd been putting off.”

Questions?
Is this just ChatGPT with a mascot?+
ChatGPT resets every session and can't see live X or Reddit data. Prova keeps a permanent record of your score, your commitments, and your pivots, and pulls from live search on both platforms.
What happens to my idea?+
It stays in your workspace. Only an anonymized percentile rank is used for benchmarking against other founders — nothing else leaves your account.
What if I don't finish my commitments?+
The Commitment Gate blocks your next Deep Dive. Not a warning, a hard block at the application layer, until you act.
Why does a 17-year-old get to build this?+
Because the last one, Propelo, failed with zero paying users, and the reason wasn't the idea. It was having no one to challenge it.
