Joël Jean-Mairet co-founded and led Glycart, the company behind the antibody that became obinutuzumab, before Roche acquired it in 2005 and before he moved into venture investing at Ysios Capital, where he closed the firm's first fund just weeks before the 2008 credit crisis. In Spain's biotech scene, he's seen as one of the field's senior figures whose backing carries weight with international investors, and he's known for serving on the boards of companies like Inbiomotion, Splice Bio, and TiGenix while pushing for Barcelona to grow into a major European biotech hub.
About their Fund
Ysios Capital is Spain's largest life sciences venture capital firm, with ties to Spain's science leadership through cofounder Cristina Garmendia, who left the firm to serve as Spain's Minister of Science and Innovation before returning as a partner, and it has moved beyond typical venture investing into company creation through its InceptionBio vehicle, which builds biotech companies from early tech-transfer projects with a strong focus on Spain. The firm focuses on hard science areas like gene therapy, oncology, orphan CNS disease, calcification disorders, and regenerative cardiovascular implants, has backed deals such as Sanifit's acquisition by Vifor Pharma and U.S.-based Kala Pharmaceuticals, and produced three NASDAQ IPOs in 2021 alongside its oversubscribed €216M third fund.
