In this episode with Tom Moss, founder and CEO of Vital Signals, you'll hear how a near-fatal hypertensive crisis during a family vacation became the founding moment for a device that may finally solve the problem of getting accurate blood pressure readings in real life without a cuff. Tom explains why blood pressure is the single most important indicator of long-term cardiovascular health and yet one of the least accurately measured, what the cuff gets wrong, and how Vital Signals achieved the scientific breakthrough that other companies failed to crack: accurate, calibration-free blood pressure monitoring from a ring. You'll also hear about the interplay between sleep, stress, hormones, sauna, cold, and blood pressure, what the Signal Ring's data is already revealing about human arterial health, and where this technology could go over the next decade.

Tom Moss is the founder and CEO of Vital Signals, building at the intersection of heart health, technology, and everyday behavior. After his experience with undiagnosed hypertension, he became focused on why some of the most critical health signals remain so difficult and often stressful to understand.

Pre-order your Signal Ring from LIFE Market and measure your blood pressure without the cuff. Ships October 2026.
