Casana

Casana is a Rochester, New York digital-health company that builds the Smart Seat (originally the Heart Seat), a toilet-seat replacement that passively measures vital signs - heart rate, heart rate variability, blood oxygen, respiration rate and blood pressure insights - while a person simply sits, with no wearables, charging or behavior change required. Spun out of research done by founder Nicholas Conn during his PhD at the Rochester Institute of Technology, the company earned FDA 510(k) clearance in 2023 and launched a consumer version of the seat in July 2026.
