This looks great. The decisions feature, and the focus on good async, reminds me of Stride (Atlassian's failed chat product).

Chat is such a social product, even inside a company, as many here have addressed. That said, irc, hipchat, campfire, matrix, slack, zulio, lync, wave, and a hundred others have had their moments of success, and I could see this being on the more successful side.
