It really was closer to a "Saas for passive income" than a business. Anyway it was a Twitter marketing tool. Got a few high profile customers here on HN, then did some back/forth emailing with TechStars but I was 22 and couldn't understand or pitch a business. I was also inexperienced at engineering. Not to mention project management, because I failed at that, too.
Still not rich yet, but continuing to grind it out on various projects. I recently raised my first outside angel financing, ever. Come to think of it, I've really been at it for 13 years now. And "just as a hobby" programming for 7 years before that.
Keep at it..
