About
iHeart is a consumer device from VitalSines International that clips to a fingertip and estimates aortic stiffness, a measure that research has linked to risk of death from all causes, presenting it to users as an "internal age." Physician co-founder Dr. Jess Goodman built it after promising his Tai Chi teacher, a Taoist monk he had studied under for twenty years, that he would show people why the stretch between the heart and the kidneys mattered. Goodman has been explicit that it is a health-and-wellness tool rather than a medical device, and that aortic stiffness responds to exercise, diet and stress reduction. The company has since added a remote patient monitoring offering. It is unrelated to iHeartRadio.
Backers
No investors are named in any source found; the company has described leading its own investment rounds.
