I started https://kernl.us https://kernl.us last May and brought it out of beta in January. I've been growing at the rate of around 5 new paying customers a month. After the closed beta I started out with about $140 / month in profits, which has grown to $330 / month over time. The growth rate has been pretty steady, but nothing so large that I could go full time on it.
