Metellus AG

Metellus AG

Metellus AG began in 2008 as a multi-family office anchored by the Wietlisbach family. Urs Wietlisbach, co-founder of Partners Group, supplies the primary capital base alongside other Swiss principals. The firm maintains its headquarters at Gartenstrasse 10 in Zurich. Metellus targets deep-technology wireless systems built on semiconductor foundations and novel immune-modulation therapies for chronic inflammation. Confirmed positions span AI-heavy applications such as humanoid robotics, space communications, and full self-driving automotive uses. The office also backs biotechnology programs that address root causes of autoimmune and allergic disease. Geographic reach covers North America and Western Europe, with additional real-estate holdings in the United Kingdom and Latin America. Investment structures include direct co-investments, SPVs, private equity, and select real-estate vehicles. Dara Capital appears as a recurring co-investment partner on technology and semiconductor transactions. The team lists three named principals and maintains membership in SECA, the Swiss Biotech Association, and the Swiss FinTech Association. Boris Battistini serves on the advisory board of the DLT Science Foundation. No headcount figure is published. A Swiss real-estate development portfolio and an international mixed-use program sit alongside the technology holdings. No operational event from the last twenty-four months appears in public records. Metellus operates with an active-ownership mandate that places principals on portfolio-company boards and leadership teams. This structure differs from passive family offices by embedding operational involvement from seed stage onward and by maintaining direct relationships with university research groups for deal sourcing and talent validation.
