Cruxproof - The idea validator that's allowed to say don't build
by•
Test a startup idea against live competitors and prices, then build a page to test it. Launch week: verified accounts get $10 credit for two validations, no card, while spots last. Builds are paid. AI research can be wrong; check the linked sources. app

We built this because every free idea validator we tried was a lead magnet, and lead magnets flatter you.
Cruxproof goes the other way. It attacks the premise first with live research, takes competitor pricing from the vendor's own page rather than from roundup articles, and it is allowed to come back and say don't build. Most ideas come back as reshape, which is a narrower or differently priced version that survives.
Two honest caveats.
It can be wrong. It researches live and cites as it goes, so check the two or three findings your decision actually turns on against the linked sources.
And before launching we pulled the search volume for our own category. The biggest term is around 110 a month in the US and the category is shrinking. We are here anyway, because the problem looks real even where nobody is googling for a tool.
Launch week offer: $10 free credit, enough for two validations, no card, 100 spots. Site builds are paid ($7 launch price for the first 50). The feedback we want most is where the verdict feels wrong to you.
