Marc Janssen


A strategist through and through. It’s hard to throw Marc off balance, always calm and solution-oriented. With an impressive résumé and as the founder of Holtburgh, he focuses mainly on managing large real estate projects in the Netherlands and Germany. But his expertise is broad: he’s often sought after as an advisor in international markets and acts as an investor, asset manager, and project manager. He has an exceptional talent for building connections with people.


The foundation of the company and always within reach.
