The Gap

Most cardiac emergencies happen
when no one is watching.

Your Apple Watch can detect AFib. But it can't call your daughter when you collapse at 2am. It can't text your cardiologist your last 72 hours of data. And it definitely can't predict a heart failure episode six days before it happens. SamaBeat can.

How it works

Wear it. Forget it.
It's watching for you.

01 — Always sensing

Five sensors, around the clock

Five sensors sample your heart rhythm, blood oxygen, blood pressure, skin conductance, and movement — continuously, silently, around the clock. No button presses. No phone required.

02 — AI understands

On-device machine learning

On-device ML fuses all five signals to detect arrhythmias in real time, spot early signs of heart failure decompensation, and predict cardiac events up to 6.5 days before they happen.

03 — Gets you help

Calls for help from your wrist

When SamaBeat detects a crisis, it vibrates to confirm. No response in 30 seconds? It calls your emergency contacts and sends your GPS location + ECG data directly over cellular.

04 — Built-in Cellular

Phone dead at 3am?
SamaBeat still calls for help.

Scenario 01
Phone dead at 3am?

SamaBeat calls for help directly over LTE-M. No Bluetooth. No Wi-Fi. Your wrist is the phone.

Scenario 02
False alarm?

30-second confirmation window before escalating. One touch to dismiss. No panic.

Scenario 03
No cell coverage?

Data queues locally and syncs when coverage returns. Not a single heartbeat is lost.

Scenario 04
Battery low?

Emergency-only mode preserves help-calling capability down to 5% battery.

Scenario 05
Subscription lapsed?

Emergency calls always work — regardless of subscription status. No exceptions.

Scenario 06
Traveling abroad?

Built-in eSIM roams across 200+ countries. Your heart guardian travels with you.

07 — The Opportunity

A $30.7B problem.
No wearable has solved it.

6.2 million Americans live with heart failure. 23% are readmitted within 30 days. The total annual treatment burden is $30.7B — and climbing.

Apple Watch detects AFib. But it can't predict decompensation, can't contact emergency services independently, and isn't cleared for clinical remote patient monitoring. SamaBeat fills every gap.

With FDA 510(k) pathway underway, CMS RPM reimbursement eligibility, and a direct-to-consumer model starting at $199, SamaBeat is both a consumer product and a clinical tool — two revenue streams from one device.
