Sunrise Group

ABOUT SUNRISE GROUP Sunrise Group is building the future of sleep health by combining breakthrough technology with expert care. We started in 2015 with a straightforward idea: sleep diagnosis should happen in the comfort of your own home, not in a hospital. To make that possible, we created a first-of-its-kind chin sensor, carefully validated through clinical research, reviewed by leading sleep experts, and cleared by the FDA. Since then, Sunrise Group has grown from a single innovation into a complete sleep health company. We now design advanced diagnostic and treatment solutions, and we deliver care directly to patients through Dreem Health, our digital sleep clinic.
