Analyse your fitInvestment thesis
Meltwind Advisory LLP serves as the due diligence and portfolio management team for Jonathan Milner, founder and former CEO of Abcam. Jonathan focuses on investing in Series A and Series B life science tools and platform therapeutics companies, supporting them not only with capital but also with the experience and insights needed to scale. Meltwind backs innovative companies that aim to deliver better health outcomes through cutting-edge science, with a portfolio spanning diagnostics, therapeutics, and enabling technologies. Jonathan invests as an angel across the life sciences, building a collaborative ecosystem of innovative companies and working on syndicate rounds — having deliberately "resisted the urge to create a venture capital fund" in favour of direct, hands-on engagement with early-stage founders.
Notable quotes
“Despite much interest, I have resisted the urge to create a venture capital fund, and my focus for the future will be to continue to invest in innovative early-stage life science and high-tech companies, working on syndicate rounds with Mike Murphy and Oliver Sims at Meltwind Advisory. This year alone, I have invested approximately £20M and I hope to increase this moving forward.”
“One of the most exciting fields, for me at this moment, is the cell therapy space. I think that companies working within this space will have a real impact on areas with high unmet clinical need.”
“To enjoy what you do is the key to progress. It's also important that, no matter the problem faced, you never give up! Experience is invaluable, and the more you gain, the better prepared you will be.”
