A note from Daniel

I made my share of founder mistakes. The most expensive one I see is building for months before talking to a single customer. Seven days of honest conversations can save you that.

Questions

Is it really free?

Yes. The guide is free, and StartWise’s Idea Validation Exam is free to take.

What if the answer is stop?

Then seven days just saved you months of building. A clear stop or pivot is a good result, and the guide shows you how to make the call.

I don’t know anyone with the problem. Where do I find them?

Step 2 of the guide covers exactly that: where to find 20 people who have the problem, without paying for ads.
