Crait

Crait is an application for secure messaging and collaboration. In practice that means replacing internal email with channels and direct messages.

The natural audience is every team. They also list Messaging and Mobile Apps, so expect those to show up in the feature set. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

Crait is based in Chicago, Illinois. Their site is craitapp.com.

Before you commit, look at search, retention policies, and external guest access. A short pilot with your real data tells you more than any demo.
