Build Check (for Outsiders)

This is actually a problem a lot of founders don't realize they have until they've wasted months building something nobody asked for. Build Check seems to be a validation framework for people to stress-test their app ideas before they pour their savings into development — basically a "why are you even doing this" checklist disguised as a product. The concept is solid, but I'd need to see the actual mechanism to know if it's more than just a bunch of obvious questions dressed up as strategy.
