Tresono Family Office
Tresono Family Office began in 2010 as the private investment office for Peter Unger after he sold Auto-Teile-Unger. Stephan Knichel and a team of former Sal. Oppenheim executives expanded the platform to serve additional families and foundations. The firm maintains headquarters in Cologne. Allocation spans public equities, private equity, private credit, hedge funds, infrastructure, natural resources and real estate. The office executes through direct co-investments, SPVs and fund commitments. Confirmed positions include the Blockchain Strategies Fund, a German Forestry Portfolio and multiple Cologne commercial assets. Activity reaches Europe, North America and Asia. Investment stages cover seed and Series A alongside buyouts, growth, secondaries and special situations. The firm employs no disclosed headcount figure. It holds properties such as Schanzenstrasse 22-28, DuMont Carré and The Q Nürnberg. Adjacent vehicles include the Tresono Foundation. Angela Müller-Valkyser serves on the board and participates in 100 Women in Finance. No operational events from the last 24 months appear in available records.
