Circle Eleven
Circle Eleven is a Hamburg multi-family office providing access to private equity funds for families and institutions since 2014.
Circle Eleven
Circle Eleven was founded in 2014 by a group of German and Swiss investors seeking to deploy their own capital into private equity funds. Alexander C. Binz and Thorsten Boll serve as managing partners. The firm opened its platform to external families and institutions in 2015. The firm commits to buyout, growth, venture capital, and special situations funds. It also executes direct co-investments and secondaries. Confirmed relationships include Main Capital Partners, FTV Capital, Advent International, TA Associates, and Vitruvian Partners. Geographic coverage spans Europe, North America, Asia, South America, and Oceania. Asset classes include private equity, enterprise software, and AgriTech & FoodTech. The team comprises more than fifteen professionals across Hamburg and Munich. Supervisory board members include Prof. Dr. Stephan Schüller, Sebastian Braun, and Dr. Andreas Richter. In December 2025 the firm published its annual investor letter and 2026 outlook. Adjacent vehicles are limited to the core multi-family office mandate. Circle Eleven maintains a club-style structure that allows participating families to co-decide on fund selections and co-investment opportunities. This governance model keeps decision rights with the capital owners rather than delegating them to an external allocator.
