How Do I Know If My Startup Idea is Good?
By Astra Stratman · April 27, 2026
Your idea is good enough when you can answer three questions: Is the problem real? Can you name one specific customer who has it? Does that customer currently spend money to solve it? If all three are yes, start. Research from 300,000 founder interactions shows that idea quality barely predicts execution. Customer clarity and action within the first 10 minutes predict it far better.
Most founders evaluate ideas the wrong way. They ask: is this big? Is it differentiated? Is the timing right? Those are interesting questions, but they are downstream of a simpler one: do you know exactly who would pay you for this and why?
The three-question test is binary. It is not a 1 to 10 score. Either you can name one customer (with a job title and a context, not "small businesses"), or you cannot. Either they spend money on the problem today, or they do not. Either the problem is observable in the world, or it is your hypothesis.
If any answer is no or vague, the next step is not building. It is finding out. One conversation with a real person is worth more than a month of market research. The founders who actually build something are the ones who treat the gap between "I think" and "I know" as their main job for the first two weeks.
