Your idea needs a reality check.
Finding a problem is easy. Proving it's real is harder. Knowing someone will pay to solve it is the part most people don't know how to test.
Find out how with Cat.
Take the Pressure Test
Answer 7 questions about your idea. Cat scores your answers, flags the assumptions you're making, and gives you a verdict: Kill, Pivot, Caution, or Build — plus a specific to-do list to take it from “this could be good” to “ready to build.”
Free • 2 minutes
Run the Validation Suite
Three structured phases — Problem, Solution, Demand — that test whether the foundation under your idea is solid or shaky. Each phase scores independently, surfaces warning signals, and tells you exactly what to fix before you spend money building.
Free • 15 minutes
Go Pro
Work with Cat as your co-founder through a 10-phase guided journey from validated idea to live product. Cat generates your pitch, outreach messages, landing page copy, and launch plan — built from your actual answers, not templates. You can't skip ahead until you've done the work.

Not a score. A verdict.
Cat doesn't give you a percentage and wish you luck. You get a clear call on what to do next.
Kill
Stop. The evidence says this won't work. Cat tells you why and saves you months.
Pivot
Something's here, but not what you think. Cat shows you where the real opportunity is.
Caution
Proceed, but with open eyes. Specific risks need addressing before you go further.
Build
The evidence supports this. Go. Cat gives you the plan to execute.
