Happy Health

Happy Health makes the Happy Ring, an FDA-cleared medical-grade smart ring that combines proprietary biometric sensors and generative AI to deliver clinical-grade accuracy for sleep and health monitoring. The company's Happy Sleep platform provides an end-to-end sleep medicine experience: patients take an FDA-approved sleep test using the Happy Ring, see a board-certified sleep doctor, and begin personalized care—all from home. The ring continuously monitors sleep, blood oxygen, heart rate, activity, temperature, and brain activity signals. Founded in 2019 by Dr. Dustin Freckleton, Sean Rad (Tinder co-founder), and others, Happy Health has raised $60M in a Series A led by ARCH Venture Partners.
