You don't.

First you find a problem, then solve it. Go read everything on https://stackingthebricks.com/

(I've been there. Built a product. Talked to potential users to try to find a problem it would solve, they talked about their problems. We ignored those problems, focused on our technology instead. Far far better to find the problem first, and then build a product.)

A little warning stackingthebricks is a semi-advice site designed to get you to need the rest of the advice, buy buying the course. Which isn't cheap.

I learned enough just reading the free stuff to make a product with revenue. But yes.

You're like the physicists that stayed in the casino, then. :-)

FWIW I don't think he's asking how to find a problem that his already-built solution solves.

He's asking how people found the problem they ended up working on.
