Pre Au Lion

Pre Au Lion

Pre Au Lion operates as a single-family office based in Brussels. Jean-Louis Waucquez serves as principal and key director after prior roles at Bourbon and Degroof Petercam. The office traces family connections through the Delwart network and the Fondation Anne Delwart. The firm allocates across hedge funds, private equity, real estate, infrastructure, natural resources and private credit. It targets pre-seed and seed stages with exposure to biotech, enterprise software and ESG themes. Confirmed geographic reach covers Europe, Africa and Oceania. Positions include direct holdings through Luxembourg vehicles such as Lion/Katsu Investments S.à r.l. and Optilian Participations S.A. The office lists three professionals in operating roles. Vincent Gombault acts as director after serving as managing partner at Ardian. Camilla Sophie Motterm holds the chief financial officer position. Jacques de Chateauvieux maintains a long-term advisory link through Bourbon and Jaccar Holdings. Pre Au Lion structures its governance around family principals and select external partners rather than external fund commitments. This setup keeps decision authority inside the Waucquez-Delwart circle while allowing co-investment access through Ardian relationships.
