Stream

Stream builds chat and feeds for applications at scale in a fraction of the time and cost of developing in-house. The job it does: replacing internal email with channels and direct messages.

It makes the most sense for every team. They also list Communications Infrastructure, Developer APIs, Messaging and Mobile Apps, so expect those to show up in the feature set. As a mid-sized product team themselves (51 to 200 people), they tend to serve customers of a similar scale best.

Stream is based in Boulder, Colorado and around since 2014. More on getstream.io.
