Recurring demand. Built-in customers. Zero noise.

the best product are these kind of, let's not say too niche, but something that's for a specific industry. Like another iPhone case is probably not the best thing to try to invent.

Right.

It's been done a million times. Like how different is it going to be? But specific things like that, or I did this project for this fire truck company and like they have these very specific like tools they use for firefighting and like they, they have specific Like the way they put installed into the fire truck, they have special fixtures for that. And that is the kind of thing that like every, 'cause every fire truck company has the same tools. They get the newest equipment every year. And when they, these guys create these like cases or like fixtures to hold it, every single company's gonna buy one because they're all gonna have to find a place to put it in their truck. And it all has to be custom made.

These kind of products really do well.
