Lots of great software has been developed by just one or two talented developers and went on to lead the market with millions in sales. Think WHMCS, Dovecot, PHP, Exim, SQLite, just to name a few. They’re now powering huge parts of the world’s infrastructure, with millions of dollars in sales for some of them. cPFence, for another tiny but shiny! example, is built by only two coders , the rest of our team handles support, admin, and sales.
Our guess is that Enhance is probably similar, maybe 2–3 developers in total, and most likely only Adam has full access to the entire codebase while the others work on specific parts. Also, Adam was the owner of a successful hosting company that got acquired by GoDaddy, so he definitely knows his way around this market.
