Yo

Yo is a simple and efficient single-tap zero character communication tool. The job it does: replacing internal email with channels and direct messages.

Who is it for? Mostly every team. They also list Communications Infrastructure, Messaging and Mobile, 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.

Yo is based in San Francisco, California and around since 2014. Their site is justyo.co.
