About the Company

About Us


Simply put, we believe in the power of sleep.


As sleep health champions, we want more and more people to wake up to a brighter day every day. And, we are making daily progress, as we help more organizations see sleep as transformational and a foundational pillar of health. We strive to give more access to the technology and care they need to lead fuller lives.


Our depth of knowledge in the science of sleep gives us a unique perspective on sleep as a critical intervention strategy in chronic disease. We help people see the right problem and the right way forward, elevating not just our solutions but also advancing the field of sleep medicine.


Our vision is to work with our partners — employers, health systems, health plans, government agencies, provider groups and others committed to transforming care — to expand sleep health care to where it is needed, so it can take its rightful place in the healthcare ecosystem.
