Investor Connect: John Kim of Aphelion Capital on Cardiovascular & Brain Health Investing

May 22, 2026 by investor

In this episode of Investor Connect, we welcome John Kim, Managing Director at Aphelion Capital, a healthcare-focused venture firm investing in early and mid-stage medical device and digital health companies. 

John shares Aphelion’s evolution from an evergreen, medical-device-only strategy to a stronger focus on cardiovascular and brain health, including a mission-aligned fund built with the American Heart Association, alongside a smaller home health effort. He discusses how the firm became fully remote after COVID, enabling efficient sourcing and meetings with companies nationwide, and explains what he looks for in opportunities—especially reimbursement pathways, clinical need, capital requirements, and experienced teams. 

John also covers founder traits tied to performance, improving sentiment around exits and acquisitions, how portfolio construction has shifted toward companies with stronger human data and commercial traction, the challenges of investing in standalone AI without defensibility.
