Happiest Baby

Happiest Baby is a consumer sleep-technology company founded by pediatrician Dr. Harvey Karp, best known for the SNOO Smart Sleeper - an FDA-authorized responsive bassinet that uses sensor-driven motion and white noise to soothe infants and improve sleep. The company also sells the Sleepea swaddle and sleep sacks, runs a companion mobile app with parenting guidance, and operates a healthcare/hospital program. Its connected SNOO hardware communicates in real time over PubNub; Happiest Baby publishes no official public developer API, and the only programmatic access is via community-built wrappers around the undocumented mobile-app API. Backed by GV and Obvious Ventures.
