RIO ASI
Rafał Brzoska and Omenaa Mensah established RIO ASI in Warsaw. Brzoska created Integer Capital Group and its flagship InPost delivery network. Mensah contributes operating experience across multiple businesses and leads parallel philanthropic vehicles. The office allocates across private equity, real estate, direct co-investments and fund commitments. It targets buyouts, seed rounds through Series E and maintains exposure to consumer retail, services and technology, manufacturing and real estate. Confirmed activity remains inside Europe. Portfolio construction mixes direct SPVs with external managers and includes holdings such as Rockfin S.A. alongside co-investor Capmont Private Equity. No public headcount or AUM figure exists. The firm lists no additional offices beyond Warsaw. Philanthropic structures operate separately through Omenaa Foundation, Rafał Brzoska Foundation and OmenaArt Foundation. Omenaa Mensah also serves on the Africa Acquisitions Committee at Tate Modern. RIO ASI maintains a single-family ownership structure with no external capital or multi-client platform. Investment decisions stay inside the founding principals and their immediate operating partners.
