About Circadia Health
Circadia Health is a growth-stage healthcare AI company on a mission to prevent avoidable hospitalizations and transform senior-care operations. Our Circadia Intelligence Platform combines:
Contactless sensing that monitors respiration and motion with medical-grade accuracy
Predictive analytics & agentic AI workflows that detect 85% of preventable rehospitalizations ~11 days in advance
Enterprise integrations that embed insights directly into EHR, care-coordination, billing, and compliance systems
Today our technology touches 40,000+ post-acute patients daily across skilled-nursing, home-health, and home-care networks. We are backed by leading healthcare and AI investors including Khosla Ventures, Village Global, Headline, and Eric Yuan (CEO of Zoom).
