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.
Olivia Lew
Olivia Lew runs Casana, a Rochester, New York company that turned a toilet seat into an FDA-cleared cardiovascular monitor. A former General Catalyst principal and Capgemini consultant with an MBA from Georgetown's McDonough School of Business, she was an early investor in Casana before joining as an operator. She sits on the Boston American Heart Association board and has spent the last few years arguing, in podcasts and press, that the most reliable way to check on someone's heart is to stop asking them to do anything at all.
