Digital health company Happy Health has secured $75 million in Series A funding to continue building its artificial intelligence-powered platform for continuous home-based care. ARCH Venture Partners and OpenLoop led the financing round.
The Austin, Texas-based company is focused on continuous physiological monitoring and physician-guided care delivered in the home. Its first application targets sleep, which company executives describe as offering one of the richest windows into human physiology. The company is developing its platform around the idea that ongoing monitoring can provide physicians with more information about an individual’s health status over time.
Funding Supports Continued Development of Home-Based Care Platform
Happy Health’s platform continuously creates an individualized physiological baseline for each user rather than comparing patients with population averages.
According to the company, clinical-grade sensors collect more than 2.8 million biometric measurements every night. Artificial intelligence and first-principles physiological models are then used to help physicians distinguish meaningful biological changes from normal day-to-day variation.
Company executives said the platform focuses on determining whether a person still resembles their own established physiological baseline rather than assessing them against broader population benchmarks. They stated that the system is designed to identify changes specific to an individual, with physicians using the resulting information as part of clinical decision-making.
Paul Berns, managing director at ARCH Venture Partners, said the company is demonstrating how healthcare can move into the home by combining continuous physiological monitoring with physician-guided care. He also said that many diagnoses may not need to take place inside a hospital setting when care is supported by continuous monitoring and physician involvement.
Sleep Medicine Platform Built Around FDA-Cleared Smart Ring
Happy Health’s first offering is centered on sleep medicine through the Happy Ring. The clinical-grade smart ring first received U.S. Food and Drug Administration clearance in October 2024.
The company’s sleep platform, called Happy Sleep, includes a clinical care team of board-certified sleep physicians. According to the company’s website, the platform is in-network with most major health insurance plans, including Blue Cross and Medicare.
In June 2025, the Happy Ring received a second FDA clearance for at-home sleep testing. The company said the authorization made it the first FDA-cleared smart ring for multi-night sleep testing and 24/7 biometrics. The approval expanded the device’s role within the company’s sleep-focused platform and added at-home sleep testing to its capabilities.
Device Targets Sleep Disorders and Broader Health Monitoring
According to the company, the device can diagnose obstructive sleep apnea, insomnia, and other sleep-related conditions in as few as three nights with 98% accuracy.
Happy Health says that each night the body reveals changes across respiratory, cardiovascular, neurological and metabolic systems, often before symptoms appear. Company executives stated that the same platform could eventually support earlier physician-guided detection and management of cardiovascular, metabolic and other chronic diseases.
Discussing the motivation behind the company’s work, Happy Health founder and chief executive officer Dustin Freckleton said, “We’ve built a healthcare system that waits for people to become sick before it acts.”
Freckleton also said he experienced a stroke at age 24 and went undiagnosed with sleep apnea for another seven years despite it being a known stroke risk factor. He said the company was created to help physicians detect disease earlier and change how care is delivered. According to Freckleton, the goal is to help identify disease before patients experience the most serious outcomes and to support a different approach to care delivery through earlier detection.
Happy Health Raises $75 Million in Series A
Happy Health has raised $75 million in Series A funding to expand its AI-powered platform for continuous home-based care. The financing was led by ARCH Venture Partners and OpenLoop, giving Happy Health additional resources to scale its technology and clinical capabilities.
The funding marks a significant step for Happy Health as the company works to move more healthcare services from traditional clinical settings into patients’ homes.
Happy Health Starts With Sleep Apnea
Happy Health is initially focusing its platform on obstructive sleep apnea, a common condition that can remain undiagnosed for long periods. The company uses an FDA-cleared smart ring to collect physiological data and support at-home diagnosis.
