What it does for you
Does your idea hold up? Test it before you build
A product idea rests on assumptions nobody has checked. This agent lists what must be true for it to work, ranks each assumption by importance and evidence, then suggests a low-cost test for the riskiest ones.
- Spot the assumptions that could sink everything
- Set your success bar before the test, not after
- Don't build on air: nothing validated without proof
