The company I work for, and similar companies, will never use this let alone pay money for it without being able to host it in-house.

We're a scrum house, but the security implications of having all our goals in such exquisite detail on someone else's servers presents too much risk.

I'm not saying you're wrong for doing this as a hosted webapp, but there is a segment of potential customers who will never use it (I have no idea how big that segment is).
