Senior🎓
Top SchoolJohn Sjolund is a serial founder and CEO with 10+ years of experience building user-driven diabetes products that scale globally, from Timesulin to Bigfoot Unity and now Luna Diabetes. He blends big-picture strategy with hands-on product and operational leadership to deliver regulated hardware-software solutions that improve safety and quality of life for people using insulin pens. A named inventor on 30+ patents and an early builder of open-source automated insulin delivery systems, he’s recognized for patient-led innovation and practical commercialization—wins that include NHS recognition and cross-border exits. John teaches digital health at UC San Diego and has advised public-sector entrepreneurship initiatives, signaling a rare mix of academic, policy, and startup depth. Based in San Diego, he’s as comfortable managing contract manufacturing and regulatory pathways as he is racing dirt bikes in Baja, a hint at his appetite for high-risk, high-reward challenges.
