Investment thesis

The firm focuses exclusively on the healthcare sector, leveraging deep expertise and a broad industry network. It invests through two strategies: an Innovation platform backing innovative medical solutions from seed to Series B (via Mérieux Innovation 2, with checks of €3m to €15m), and a Buyout platform supporting more established companies (via Mérieux Participations 5, with checks of €20m to €80m, more with co-investment). Both target companies across Europe, ranging from start-ups to established sector leaders.
