Watrium

Watrium functions as the single-family office for the Wilhelmsen family, whose holdings trace to the Anders Wilhelmsen Group. Anders Christopher G. Wilhelmsen holds the role of CEO and third-generation owner. The firm allocates across private equity, venture capital, real estate, infrastructure, and private credit. Investment stages include buyout, growth, late stage, and pre-IPO. Watrium pursues direct co-investments and SPVs. Confirmed geographies cover Europe, North America, and Asia. Portfolio construction incorporates fund-of-funds commitments alongside select direct positions. The team includes Haakon Stenrød as Investment Director and Knut Olav Rød as Co-Chief Investment Officer. Additional real-asset holdings comprise multiple commercial properties in Oslo, including Oslo Atrium and Fornebu Gateway. No dated operational events from the last 24 months appear in available records. Watrium maintains a hybrid structure that combines internal direct deal execution with participation in external institutional syndicates. This setup separates family capital deployment from third-party fund vehicles.
