Former medical student Dustin Freckleton has launched health technology startup Happy Health out of stealth mode after raising 75 million dollars to develop an artificial intelligence ring for diagnosing sleep apnea.
The company emerged from stealth mode on Tuesday following successive funding rounds since 2019. Happy Health aims to accelerate the diagnosis of sleep disorders by combining biometric wearable hardware with virtual medical consultations.
Freckleton founded the enterprise following a severe personal health crisis that began during his medical training. At age 24, while in his first year of medical school, he suffered a stroke that left him temporarily paralyzed on one side of his body.
The underlying cause of his stroke remained unclear for nearly seven years until doctors diagnosed him with sleep apnea, a disorder where upper airways repeatedly collapse during sleep and interrupt breathing. He was also diagnosed with atrial fibrillation, the most common form of cardiac arrhythmia.
Medical background and startup origin
Medical research links untreated sleep apnea to a higher risk of severe cardiovascular complications, including stroke, heart disease, and diabetes. Despite these risks, the condition frequently remains undiagnosed because traditional diagnostic sleep studies require overnight stays in clinical settings.
Freckleton created Happy Health to transform his medical ordeal into a digital health solution. The startup developed a smart ring designed to collect biometric data while the user sleeps, using artificial intelligence algorithms to detect signs of sleep apnea within a few days.
The company raised 75 million dollars in total capital from investors, including ARCH Venture Partners and OpenLoop. Venture capital backing supported the company through product manufacturing, clinical validation, and regulatory approval.
Regulatory approval and platform operations
According to Freckleton, investors maintained financial backing as Happy Health reached critical milestones, culminating in obtaining market clearance from the US Food and Drug Administration for the smart ring. The most recent funding round closed in 2025.
Happy Health charges 396 dollars for its full service package. The price includes the physical smart ring, one year of continuous sleep monitoring, and access to telehealth consultations with network physicians.
Under the business model, patients complete sleep tracking at home before consulting with a physician from the Happy Health network. The doctor reviews the biometric analysis and can formally diagnose sleep apnea.
If clinical intervention is required, the network physician can prescribe targeted treatments. These include continuous positive airway pressure machines, known as CPAP devices, which deliver steady air pressure to keep airways open during sleep, or specialized dental appliances.
Market positioning and future expansion
Tens of thousands of patients have already used the platform during its development phase. Freckleton declined to disclose current figures regarding company valuation or annual revenue.
Freckleton emphasized that Happy Health differs from existing consumer health wearables by bridging the gap between monitoring and medical treatment. He said that users who want to track poor sleep quality should go to Oura, while those who want to fix poor sleep quality should come to Happy.
The founder intends to expand the platform beyond sleep apnea in the future. Happy Health plans to leverage daily biometric data collection to monitor additional chronic health conditions across its user base.
