Sleep is one of healthcare’s biggest blind spots. Access is slow, confusing and uneven, and millions of people who need help never get it. Sunrise exists to change that. Born from pioneering research on mandibular jaw movement, we built a chin-based sleep test that reinvented how sleep disorders can be diagnosed from home. That breakthrough has evolved into a full sleep-health platform: advanced diagnostic and treatment technology paired with clinical care delivered directly to patients’ homes through Dreem Health in all 50 U.S. states. Across the U.S. and Europe, our 100+ clinicians, engineers and operators share one mission: make high-quality sleep care accessible to everyone. Backed by more than $50M, we’re taking on one of healthcare’s biggest challenges: the 1+ billion people worldwide who still can’t get the sleep care they need.
