In this episode of Medsider Radio, we sat down with Young Juhn, CEO of Wellysis.

Wellysis is the Samsung spinout behind S-Patch, a lightweight wearable that enables long-term ECG monitoring without the discomfort of established cardiac monitoring devices.

Young has spent more than two decades bridging hospital and home-based care — from his early career at Johnson & Johnson, to more than a decade at Kaiser Permanente, to leading healthcare innovation at Samsung before spinning out Wellysis in 2019.

In this interview, Young shares why patient interviews should shape product design, how regulatory clearance is just the starting point for global commercialization, and why building a medical foundation before branching into consumer markets is critical for lasting adoption.
