We have multiple people involved, but I'm the only one working on it regularly. We aren't paying any dividends yet, so the majority of that goes to pay my salary. At some point, we'll begin paying dividends to everyone. That's a long way of saying there are multiple people involved, but I'm the only person getting anything out of it at this point.
I own about 70% of the company and have done the majority of the work by myself thus far. (That's beginning to change.) My investor/business partner put up a small amount of money to get us off the ground, and he helps handle more of the business side of things so that I can focus on design/development. However, I'm still pretty involved in every aspect of the business.
Short Version: Hosted Web App making just under $10,000/mo.
Using a throwaway account for this because I'd rather not share our numbers publicly yet, but in about 2.5 years since our hosted web app went live, we're generating just under $10,000 per month in revenue. That's working on it part-time for the first couple of years and, more recently, full-time.
It's targeted at developers/designers, and the growth has been very slow and steady. There's never been a break-through moment as revenue has grown at an average rate of about 3.5% per month since we launched.
