Sunfox Technologies is closing a deadly gap in cardiac care, where nearly a third of Indian deaths involve cardiac causes and ECG machines stay absent from rural, low-connectivity areas. Serving patients, rural clinicians and health centres, its Spandan ECG is a portable, battery-free device capturing a clinical-grade reading in seconds and pairing on-device AI with remote doctor review. Needing no electricity, internet or technician, it has already helped save lives.
