I run a service called Tesults for test results reporting. It's fairly new, I went from idea to first release in two months, releasing last October. I wanted it to be fast because I've spent 8-9 years launching a bunch of stuff and each one took far too long for an initial release. With Tesults I discovered users expected far more features than that first pithy release and so work has never really stopped and I think that's part of the 'improving the core product' you are referring to. I find it fascinating how little love this part of software dev can get with respect to both developer time allocation and department budgeting (hence making free to use important for most users) so Sauce Labs revenue is all the more impressive. Tapster is very cool - working on something with a cool factor like that makes it easier to get attention as I'm discovering now with a new project I'm working on (unrelated to testing).
