OpenLoop, a telehealth infrastructure platform serving over 300 organisations, has announced a shift in expansion strategy, opting for strategic investments rather than outright acquisitions. The company has invested in Happy Sleep, which makes an FDA-cleared smart ring that diagnoses sleep apnea at home in five days with 98% accuracy. Since 2024, OpenLoop has completed 13 strategic investments and acquisitions, including Season Health and Hey Revia. The investment approach allows the company to support operators in categories where it already runs clinical operations — such as sleep, weight management, and nutrition — without the integration burden of full acquisitions. OpenLoop has operated Happy Sleep's clinical diagnostics, including provider review, since April 2026. The company plans to pursue additional equity investments in consumer healthcare companies this year.

Happy Health, an Austin-based digital health company, secured $75 million in Series A funding led by ARCH Venture Partners and OpenLoop to expand its AI-powered home care platform. The startup's FDA-cleared Happy Ring is the first smart ring approved for multi-night sleep testing and continuous biometrics. It diagnoses obstructive sleep apnea and insomnia in as few as three nights with 98% accuracy, according to the company. The platform collects over 2.8 million biometric measurements nightly, building individualised physiological baselines rather than comparing patients to population averages. Happy Sleep includes board-certified sleep physicians and accepts most major insurance plans, including Blue Cross and Medicare. The company plans to extend its continuous monitoring approach to cardiovascular, metabolic, and other chronic diseases.
