Who this is for
Most business ideas die expensively when they could have died cheaply. The difference is sequencing: building first tests the riskiest assumptions last, after the money is spent. Validation flips the order, asking what must be true for this idea to work, which of those is least certain, and what is the cheapest honest test of that one thing.
Use the generator to draft the idea as a structured plan, then read it as a list of claims: people have this problem, they pay to solve it, they would switch, the economics work at your price, you can reach them affordably. The notes below help rank those claims and design tests that real customers can fail.
