The Sunrise Group has raised $29 million to expand Dreem Health, its recently acquired digital sleep clinic.
When the company was founded in 2015, it developed an FDA-cleared mandibular sensor for at-home diagnosis of sleep apnea. It embarked on a journey last year to provide end-to-end sleep care for patients when it acquired Dreem Health.
Laurent Martinot, co-founder and CEO of the Sunrise Group, explained that the majority of Americans suffer from a lack of sleep. Bad sleep is linked to a host of co-morbidities like obesity, hypertension and depression, he said.
According to Dreem Health’s 2025 State of Sleep survey, conducted by the Wakefield Research Group, only 7% of Americans report feeling well-rested every day when they wake up. The main disruptors of sleep, in order of prevalence, are stress and anxiety, environmental factors and snoring or breathing difficulties.
The latest fundraise was led by Eurazeo, with participation from Amazon’s Alexa Fund, WE International, Kurma Partners, Vives Fund, Majycc (an UI Investissement fund), Namur Invest, Seventure Partners, Investsud, Sambrinvest, Noshaq, IMBC and Invest.bw.
With the infusion of cash, the company will build out Dreem Health’s offerings nationwide and attempt to recruit more providers to the platform. In the future, the company wants to build an AI co-pilot for sleep medicine to assist providers during and between consultations, providing real-time documentation and decision support.
It already uses AI for care coordination, message triage, call handling and billing. Martinot explained that the company is shifting to build its AI capabilities in-house rather than buying solutions from other vendors.
“Our first strategy was more to assemble and to buy, basically to assemble different tools,” Martinot said. “But the more we go about this, the more we realize that if we want to take the step after, you need the full context of the patient … We have information from the first touch point to all the lifetime of our patients. So we can really understand the story of their sleep, how it evolves, how it personally relates to other diseases, for example. To make the best of that information, we feel building this thing to be the way forward.”
The Sunrise Group helps solve two key problems: the lack of sleep specialists and the difficulty of sleep studies.
Often, to diagnose a sleep condition, patients must undergo a sleep study. Patients must either go in-person to a sleep clinic, which often have long wait times and are time-consuming and burdensome, but more accurate.
The alternative, at-home sleep studies, have traditionally been less accurate due to the lack of good diagnostic equipment. The Sunrise Group developed a more comfortable device to test for sleep apnea, which is a lighter weight and designed to be worn for multiple nights.
Close to a billion people worldwide have sleep apnea, and roughly 80% of cases go undiagnosed, Martinot said. After patients have completed their sleep studies, Dreem Health offers online appointments with sleep specialists around the country.
