Hear what your heart is trying to tell you.

CSM attaches to any stethoscope, records 20 seconds of heart sounds, and our AI flags abnormalities instantly — so early screening can happen anywhere, not just where cardiologists are.

Your heart warns you early. We just can't hear it.

Heart disease is the world's leading cause of death, and in its early stages it has no symptoms. The only way to catch it is regular screening — but specialists are scarce, and almost absent outside big cities and across island communities.

18M+

people die from cardiovascular disease every year.

80%+

of them never had the chance to be diagnosed.

1 : 44k

one cardiologist for every 44,000 people in the Philippines. In Thailand, 1 for every 28,000.

A specialist's ear, clipped to any stethoscope.

CSM is a small extension that plugs into the stethoscope you already use. It captures clean heart sounds and sends them to the CSM app, where our AI does the listening.

01 · Connect

Plugs into your stethoscope

No new equipment to learn. Keep the stethoscope your hands already know.
