Slap

Slap: Sounds like a plan has reimagined the social invitation as a group event story to pregame the future with your friends. The job it does: replacing internal email with channels and direct messages.

The natural audience is every team. Related areas on their profile: Messaging, Mobile Apps and Social Network. 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.

Slap is based in New York, New York. More on slap.events.

Things worth asking about: search, retention policies, and external guest access. Ask for a trial on your own data, not a canned demo.
