## About

Aurèus was founded in 2009 through the merger of independent Dutch wealth managers Boer & Olij Securities and Attent Vermogensbeheer. Its capital base stems from the partners' entrepreneurial track record in securities brokerage and asset management. The core family served is the Hilti family, whose wealth originates from the power-tools and construction-systems group founded by Martin Hilti in 1941. Family governance flows through the Martin Hilti Family Trust, which is stewarded by a board of family and non-family trustees including Pius Baschera and Christoph Loos. The firm allocates across a diversified mix of public-market securities, private equity, real assets, and fund-of-funds vehicles. Investment-stage coverage spans early-stage venture through late-stage expansion, growth equity, mezzanine, and secondaries, with a particular emphasis on co-investment opportunities in the healthcare-services and biotech sectors. Geographic mandates are confirmed in North America, while the office's core European base shapes its sourcing and manager-selection lens. Deal-flow preferences lean toward fund-of-funds structures seeded by relationships cultivated through the trustees' overlapping networks. The Amsterdam-headquartered office operates as part of a broader private-wealth architecture that includes Aurèus Service AG, led by CEO Klaus Risch, and the Hilti Foundation, the family's primary philanthropic vehicle. Although precise team headcounts remain undisclosed, the family office's governance integrates operating-company executives directly into its trust board—Christoph Loos, Hilti Group's CEO, serves as a trustee, while Pius Baschera, a former Hilti Group CEO and current LGT Group board member, links the office to Liechtenstein's princely banking dynasty. No recent operational events were publicly disclosed in the past 24 months. The office's structural differentiator lies in its layered governance design—outsourcing trust stewardship to both family principals and independent Swiss legal professionals, such as Tis Prager of Prager Dreifuss AG, while embedding the management of the primary operating asset directly inside the trust board. That architecture separates generational wealth oversight from day-to-day investment and philanthropic decision-making, a configuration rarer among continental European multi-family offices than in their Anglo-Saxon counterparts.
