Interesting, there is definitely a market for this. Some of our customers at getstream.io use the API to build their own Facebook style apps for within their organizations. Building your own in-house social networks is of course quite a bit of work. Facebook should be much easier to get up and running.

The pricing seems really low for small firms and extremely expensive for larger ones. That sounds like a challenging position for the sales team working on this project.

I wonder if this comes with the full range of personalization algorithms for the feed.

Also wonder how they will handle the extensive customization that most enterprise customers will request.

It's a solid idea though, pretty similar to what Slack is trying to achieve.
