Takes a product idea and maps out assumptions across eight risk categories, from the standard four (value, usability, viability, feasibility) to the ones that kill new products: go-to-market, strategy, ethics, and team dynamics. You describe your concept and it thinks through failure modes from PM, designer, and engineer perspectives, then flags assumptions with confidence ratings and test suggestions. Built on Teresa Torres' continuous discovery framework but extended for the full startup gauntlet. Use it when you need to pressure test a new venture or product concept before you're too invested to see the holes clearly.
