Abacon Capital
Albert Büll established Abacon Capital in 2021 after building B&L Group into a major real-estate developer and participating in the growth of Encavis. The office manages the resulting wealth through a single-family structure headquartered in Hamburg. Abacon deploys capital into Energy Transition & Renewables, ClimateTech, Mobility & Transportation, PropTech and related sectors. It participates in buyouts, growth equity, public equities and early-stage rounds through direct co-investments, SPVs and fund commitments. Confirmed positions include a stake in Bitcoin Group SE and real-estate assets such as KII in Düsseldorf and Hafenpark Quartier in Frankfurt. The geographic footprint spans Europe, North America and Africa. The firm lists three named principals and maintains no disclosed headcount. It holds membership in ECORE since 2022 and belongs to the Anglo German Club and Förderkreis Internationales Musikfest Hamburg. Philanthropic vehicles include the Sopowerful Foundation and Stiftung Elbphilharmonie. Additional holdings comprise a private jet and several yachts. Abacon operates with a permanent-capital mandate that permits both public-market positions and long-hold private assets without external fund-raising cycles. This structure separates it from typical limited-life vehicles and allows direct participation in consortium deals such as the Encavis takeover.
