Axelyf
Axelyf is a Brookline, Massachusetts biotech (with an R&D subsidiary in Iceland) building next-generation lipid nanoparticle delivery systems for RNA medicines. Founded by former Moderna drug-delivery leaders, it pairs a proprietary AXL ionizable-lipid library with an AI model called ANNA to make RNA and gene-editing payloads reach the right tissue with higher potency and less toxicity. In mouse liver studies its AXL LNPs showed roughly 4-5x higher gene-editing efficiency than the LP-01 clinical benchmark at equivalent doses, without evidence of liver toxicity. The company closed $2.6M in seed funding in August 2025 to push its lead autoimmune program and lipid library toward preclinical and non-human-primate studies.
Kytopen
Kytopen is a Cambridge, Massachusetts biotech and MIT spinout building Flowfect, a non-viral, continuous-flow platform that uses fluid flow plus electric fields to deliver mRNA, DNA and CRISPR payloads into cells. The technology aims to engineer hundreds of billions of cells in minutes, removing a major bottleneck in discovering, developing and manufacturing advanced cell therapies like CAR-T and NK-cell treatments.
BreezeBio
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.
