Martek

Martek

Marcel Katz and René Katz founded Martek. The firm pursues private equity and real estate strategies for client families. Its approach draws from entrepreneurial roots without a single disclosed wealth source. Martek deploys capital through private equity, real estate, private credit, and infrastructure. It executes direct co-investments and SPVs alongside fund-of-funds commitments. Confirmed holdings include Paris Hotel Residences and Thiais Residential Project. The firm covers Europe and North America with additional exposure in Asia, Africa, and South America. No team size or AUM figures appear in public materials. Simon Wachsberg serves as Investment Director with focus on US interests. Martek maintains no disclosed adjacent vehicles or club memberships beyond philanthropic ties noted for family members. Martek structures decisions around majority ownership in operating companies. This creates direct governance involvement distinct from pure fund commitments.
