Checkin

Checkin (checkin.cc) was a Bloomberg Beta-backed social-connection platform that brought thousands of people together for structured, timed 8-minute weekly one-on-one conversations intended to spark meaningful human connection. The consumer service ceased operations on June 30, 2023; the domain now serves a shutdown notice and the only remaining contact is support@checkin.cc. The company published no public developer API, SDKs, or documentation surface, so this profile has no API artifacts to enrich beyond a live domain-security probe of the remaining host.

Checkin is profiled on the APIs.io network. Tagged areas include Company, Social, Community, Networking, and Consumer.
