Dr. Aristotelis Nastos moved from a career as a bench scientist—biology degree, PhD in cell biology, a Wellcome-funded postdoc at King's College London, and running a research group at the German Diabetes Research Center—into venture capital, later overseeing a 35-company portfolio as NRW.BANK's Head of Life Sciences & Cleantech. Across his investing career he has repeatedly helped companies reach acquisition, including Direvo (Bayer), Rigontec (MSD), Scienion (Cellink/BICO), CEVEC (Cytiva), and Emergence (Lilly), with particular involvement in platform and enabling technologies like those behind Scienion and CEVEC.

Notable Investments
BioMedPartners was one of the first venture capital firms in continental Europe to focus only on life sciences, building its funds and team around Switzerland and Germany with deep ties to Roche, ETH, and the University of Basel, and its partners have personally founded and sold companies like GlycoVaxyn (to GSK) and Inositec (to Vifor Pharma). The firm has repeatedly backed specific, less obvious scientific bets—such as Claudin-1 as an anti-fibrotic target at Alentis, cancer drug resistance biology at Tolremo, and early T-cell vaccine platforms at Okairos—and its portfolio includes major exits like Tubulis (up to $5 billion Gilead deal), Cardior (Novo Nordisk), Numab/Yellow Jersey (J&J), and NBE-Therapeutics (Boehringer Ingelheim).
