No competition
There’s no competition for cookbooks on making food out of soccer balls and hockey pucks.
There’s no competition for software that charges you to find out the temperature on Mars.
There’s no competition for a service that counts how many pairs of shoes you own.
In fact, in every market that’s worth entering, there’s competition. That’s what you’re looking for. It’s a sign that people have a problem that they’re trying to solve through commerce.
The goal isn’t to find no competition. It’s to find a better way to solve the problem.
