## About

Based in Texas, US, and founded in 2019, Happy health Inc, operates as a manufacturer and developer of a smart wearable ring that allows its users to measure stress, sleep, and mood. The company was Co-founded by Sean Rad, Dustin Freckleton (CEO), Sue Smalley, Paul Berns, and Robert Nelsen. In August 2026, Happy Health, Inc. raised USD 75 million in series A funding co-led by OpenLoop and ARCH Venture Partners.

The company has developed a real-time health information tracking device that is wearable as a ring that could be paired with an iOS device and helps the user to measure his/her focus, calm, stress, sleep patterns, and more. The application offered by the company which is used to perform the features offered by the firm also offers personalized routines and coaching backed by science. It also helps to connect with close friends and family based on how they are feeling with the help of their happy ring uploaded data. The ring uses artificial intelligence to learn and make the reading more accurate.  The ring is available in US for sizes US 6-12 and weighs 4-6 grams and comes with a free ring sizing kit. It connects only with iOS devices, iPhone 6 and above. The ring offers features such as live stress, coaching, sleep tracking, bedtime guidance, trends, heart rates, etc. It automatically syncs with the user’s apple health. The ring is offered in two colours glossy white and glossy black.

The company generates revenue through a subscription-based sleep care membership model. Customers receive at-home sleep testing, physician consultations, ongoing monitoring, and continuous care through the Happy Sleep platform.

The company will use the August 2026 funding to expand its at-home health monitoring platform, strengthen its technology, and support clinical validation for detecting chronic diseases beyond sleep apnea.
