San Francisco, April 22, 2026 - Sleep Reset, the leading virtual sleep clinic treating insomnia and sleep apnea through clinician-guided, CBT-I-based care, today announced the acquisition of Chorus Sleep, a Y Combinator-backed sleep health platform. Chorus Sleep offers a wide-ranging suite of sleep support including AI-powered sleep coaching, CBT-I-based educational content, proprietary breathwork and relaxation sessions, sleep tracking, and snoring and sleep apnea support. With the deal, Chorus Sleep's platform and technology, including Luna, its AI coaching agent, join Sleep Reset's clinician-led model, strengthening its ability to deliver personalized, scalable care to the millions of people struggling with chronic sleep issues.
Chorus Sleep was built around the belief that effective sleep care requires meeting each person where they are, with the right intervention at the right time. The platform spans AI-powered sleep coaching, CBT-I-based educational content, proprietary guided breathwork and relaxation sessions, sleep tracking, and snoring and sleep apnea support, all designed to work together as a personalized, adaptive sleep care experience.
At the heart of the platform is Luna, Chorus Sleep's AI coaching agent. Luna is a user-facing coach that combines real-time interaction with longitudinal memory to guide users through structured, adaptive sleep improvement journeys, automatically tracking sleep data, identifying health patterns, logging journal entries, setting reminders, and delivering personalized guidance, all without requiring manual input from the user.
Luna becomes more effective with every interaction, building a proprietary data flywheel that grows over time. The result is a care experience that feels personal and responsive at every step, with human expertise applied precisely where it's needed most.
Chorus Sleep built its platform with a focus on enterprise and employer health deployments, reaching users across 26 countries. In those deployments, the platform achieved approximately 35% program adoption, 80% retention at month one, and over 50% retention at month six, metrics that reflect meaningful, sustained engagement across a global user base.
Across the platform, Chorus Sleep users demonstrated 30% faster sleep onset, 30% fewer nighttime awakenings, and a 20% improvement in daytime functioning, outcomes consistent with the kind of meaningful sleep improvement Sleep Reset aims to deliver at scale.
“Sleep is a complex, deeply personal health challenge, and solving it well requires both world-class clinical care and the technology infrastructure to make that care feel effortless for every patient. What the Chorus Sleep team built is exactly the kind of intelligent, adaptive technology that makes truly personalized care possible at scale. We're excited to bring this into Sleep Reset and continue delivering outcomes that change lives.”
— Shimin Ooi, CEO, Sleep Reset
"We built Chorus Sleep out of a deep belief that sleep is the foundation of good health, and that people deserved better tools to get there. What we learned along the way was that doing it right required a system that learned from each person, met them where they were, and knew when to route them toward clinical care. Sleep Reset is that clinical care."
— Ali Abramovitz Cook, CEO and Co-Founder, Chorus Sleep
Chorus Sleep co-founders Ali Abramovitz Cook (CEO) and Warren Runk (CTO) are supporting the transition in an advisory capacity. Runk is leading the technical integration of the Chorus Sleep platform into Sleep Reset's infrastructure.
