I run https://csper.io. It's a web app that simplifies some web security stuff Content Security Policy (CSP).

I helped setup CSP at a company back when I was an intern (2013). I learned that CSP can be an unpleasant experience.

A year ago I decided I wanted to do something new with my life so I quit my job and Csper was born. Hopefully it makes CSP easier for other people.

It's not super profitable, but it almost pays my rent, no complaints.
