Leo

Leo offers a disappearing messaging app and ultra-lightweight platform for one-on-one and group conversations on iOS and Android devices. Put simply, it is about replacing internal email with channels and direct messages.

Who is it for? Mostly every team. They also list Messaging, so expect those to show up in the feature set. They are a very small team, 1 to 10 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.

Leo is based in San Francisco, California. You can read more at leo.co.
