Jonathan Milner

Jonathan Milner is the founder of Abcam, the Cambridge UK-listed life sciences antibody business he scaled to a multi-billion exit, and one of the most active life sciences angels in the UK and US. (Cambridge here is Cambridge UK; the input has it tagged US but the network and patterns are transatlantic.) His angel activity centers on biotech, healthcare software, and diagnostics, with growing AI/ML-in-bio interest, reflecting the modern reality that wet-lab and dry-lab are converging. Seed and Series A, $250k+ checks, typically rolling with institutional leads or syndicating with other Cambridge/Boston bio angels. Best fit: founders with a real scientific edge, a credible technical co-founder, and a wedge into life sciences tools, antibody/reagent infrastructure, lab automation, or AI for drug discovery and diagnostics; bonus if you can articulate the gross margin and channel story, which Abcam mastered. Pure consumer health, telehealth services, or US-payer-facing digital health is not his lane. Entry path is LinkedIn (he is active) or a warm intro via Abcam alumni, the Cambridge Angels group, or Milner Therapeutics Institute. Expect him to push hard on commercial traction and channel; he is a builder, not a pure scientist, and he will want to know how you sell, not just what you discovered.
