It would be useful if the web-site had a real case-study where they show all the features in action. Right now it looks like vaporware -- like one of those sites people put up to see if there is interest in an idea.

True. We'll add better images and case-study to avoid the confusion.

And perhaps stuff like this should have on-site capability for enterprises that don't use github, gitlab and such?

I'm assuming you are talking about GitHub Enterprise, Gitlab Self-Managed and Bitbucket Server. We currently have support for Bitbucket Server and working on the rest.
