Have you looked at enterprises? AFAIK Slack and Hipchat are cloud based, which is fine for some but not all enterprises due to obvious security concerns, and if you can make self-contained and easily deploy-able system that can integrate with enterprise IT systems, particularly authentication, you may have an interesting use-case. Healthcare is another big space, where there are several startups looking at messaging where Slack etc. won't work due to HIPAA compliance and other specific scenarios. P.S. Didn't try your demo, since it wanted phone number, and sorry we don't know each other well at this time to trust you with it. :)
