## About

Resona was established in 2017 by David Giertz following the SEK 2.4 billion sale of his telecom business DGC. The firm operates from Stockholm as a multi-family office that manages the founding family's capital alongside a limited number of other families. Resona allocates across real estate, private equity co-investments, and sustainability strategies. It executes direct residential developments in Sweden and participates in forward-funding transactions. Confirmed positions include projects such as Ritorp Solna, Twintip, and Åhus Pine Park. The firm has partnered with OBOS on residential ventures and with Hines on real estate financing. Geographic reach spans Europe, North America, Asia, South America, and Oceania. The team includes CEO Fredrik Bele, co-principal Sam Giertz, and Head of Business Development Johan Bonander. No public disclosure exists on total professionals or assets under management. Adjacent activity centers on real estate holdings rather than separate philanthropic or operating vehicles. Resona maintains a hybrid structure that combines family capital with selective external families, allowing direct execution of real estate and co-investment mandates without reliance on external fund commitments.
