BreezeBio (formerly GenEdit) is a Brisbane, California-based biotechnology company that develops precision genetic medicines using its proprietary NanoGalaxy platform - a library of polymer nanoparticles capable of delivering genetic payloads like mRNA, siRNA, and CRISPR components to specific tissues without triggering immune responses. Unlike viral vectors that can only be dosed once and often provoke dangerous immune reactions, BreezeBio's non-viral approach allows repeat dosing, broad payload flexibility, and tissue selectivity across immune cells, heart, lung, and CNS. Founded in 2016 out of UC Berkeley by CEO Dr. Kunwoo Lee and CTO Dr. Hyo Min Park, the company rebranded from GenEdit in early 2026 following its $60M Series B, signaling a shift from delivery-platform licensor to full therapeutic developer with a lead program (BRZ-101) targeting Type 1 Diabetes.
Kunwoo Lee is the CEO and Co-founder of BreezeBio (formerly GenEdit), a Brisbane, California-based biotech company pioneering non-viral gene delivery through its proprietary NanoGalaxy platform. A Siebel Scholar and Forbes 30 Under 30 honoree who earned his PhD from UC Berkeley-UCSF Joint Program in Bioengineering, Lee co-founded GenEdit in 2016 alongside Professor Niren Murthy and fellow researcher Hyo Min Park, building out a polymer nanoparticle library of thousands of chemically distinct compounds capable of delivering diverse genetic payloads to specific tissues. The company has raised over $118 million including a $60M Series B in February 2026, struck a landmark $644M collaboration deal with Genentech, and rebranded to BreezeBio to signal its pivot from platform company to clinical-stage therapeutics developer advancing BRZ-101 for Type 1 Diabetes.
