I've been evaluating a lot of products in this space in the past week and I think it is a space that could do with a developer-first approach. But to do that I still want to see a path towards using it at scale that's a little more fleshed than a "talk to sales" equivalent. Even if this were open source, I would be happy to pay for someone else to host and scale it, but at least I would know I couldn't be unreasonably locked in after making my business depend on it.

OK. That's compelling enough.
