Adi Dassler International Family Office
Adi Dassler International Family Office (ADIFO) was founded by brothers Horst, Klaus and Stefan Bente — grandsons of Adi Dassler — along with CEO Julian Bradham. The firm headquartered in Sarasota, Florida draws its underlying wealth from the Adidas founder's estate. ADIFO offers investment advisory, tax & legacy consulting, and wealth management services through an open-architecture model. The firm covers asset classes including private equity, venture capital, real estate, and alternative investments. Its venture arm leAD Sports backs sports-tech startups; portfolio companies include ADvantage Sports Tech Fund, where great-grandson Alex Bente serves as principal. ADIFO also owns residential property in Wiesbaden, Germany and a luxury art collection based in Kingston, Jamaica. The firm's geographic footprint centers on North America, Europe, and the Caribbean. The team of roughly a dozen professionals is led by founding partner Allen Johnson, who previously served as director and client advisor at Alex Brown. Partners Kim Martin and Josh Renda oversee operations and client advisory. Michael J. Dolberg, CEO of Apollon Wealth Management, also serves as a partner. An innovation partnership with the Orlando Magic supports the leAD Sports ecosystem. ADIFO maintains additional offices in Wiesbaden, Germany and Nassau, Bahamas. ADIFO is structured as a multi-client family office that provides its own wealth management infrastructure to outside families and individuals, distinguishing it from single-family offices that serve only one lineage. The firm emphasizes tax-efficient, customized solutions using both US and international tax codes.
