Kalyan Sivasailam

Kalyan Sivasailam is the Founder and CEO of 5C Network, India’s AI-native radiology partner. He started 5C in 2017 in Bangalore to close one of healthcare’s most under-discussed gaps: the world is building scanners faster than it is training radiologists. India alone has over 100,000 diagnostic centres and fewer than 15,000 radiologists, and that asymmetry is widening every year.

Today 5C reads over 10,000 scans a day for more than 1,500 hospitals across 27 Indian states, with a network of 400+ specialist radiologists signing every report. The company has reported over 11 million scans. AI runs the workflow — pathology detection, structured reporting, and quality control — and humans hold final clinical accountability. Median report turnaround is under 30 minutes against an industry baseline of 24–48 hours.

The thesis behind 5C is in the name. Five, Connected — the patient, the referring physician, the diagnostician, the healthcare provider, and AI. Each one is a node; the value is in the edges. Kalyan’s argument is that the radiology workflow doesn’t need a model, it needs an operating system. That is why 5C invests as much in the human network and clinical QC as it does in the AI stack — the two together are what make scans dependable at scale.

Before 5C, Kalyan founded the Healthizen Initiative, the official grievance-redressal application for the Health Department of the Government of Karnataka, focused on preventive public health. He has also held roles at Tata Communications. He is an engineering graduate of the National Institute of Technology Karnataka.

Under his leadership, 5C has pioneered two frameworks that now shape how Indian and global teams talk about clinical AI: Generalised Medical AI (GM AI) — the move beyond narrow detectors into full-workflow radiology AI — and Hybrid Intelligence, the operating model where radiologists and AI hold complementary responsibility for every report.

Kalyan has written and spoken extensively on AI in healthcare — published in YourStory, BW Healthcare World, The Hindu, and Financial Express Healthcare; interviewed by Bloomberg, STAT News, Analytics India Magazine, CNBC-TV18, and NITI Aayog; and on stage at the Indian School of Business, ET Healthworld, RSNA 2025, and TEDx. In 2019, he was recognised in Forbes India’s 30 Under 30 list in the Healthcare category.
