What Activum does
ActivumSG Capital Management Limited is a privately held pan-European opportunistic and value-add real estate investment manager founded in 2007 by Saul Goldstein (formerly head of Cerberus Capital Management's European real estate team) and headquartered in St. Helier, Jersey, with a founding office in Berlin. The firm operates across six offices in five European countries (Germany, Spain, UK, Netherlands, Luxembourg, plus Denmark) and directly and indirectly advises on over €10bn in real estate and real estate-related investments, having raised approximately €3bn in discretionary capital from global institutional investors across four active fund vintages.
The firm executes through three strategic pillars: direct real estate, corporate platforms, and special situations. Direct activity spans hospitality (Fairmont La Hacienda, Nobu Hotel Barcelona, SLS Barcelona, Palacio Solecio, Sutton Point, Odyssey Hotel Group with 3,500+ keys), residential development (VanWonen in the Netherlands, Le Blanc in Marbella, the realized Instone Real Estate platform), senior living (Carestone Group in Germany), student accommodation (Union PBSA platform in the UK), and powered land for data centers (Zeus in Meco, Madrid). Corporate platforms are built via acquisition and merger (formart→Instone in 2014; WI-IMMOGroup+WirtschaftsHaus→Carestone in 2016/2018) and exited through IPOs (Instone, Frankfurt, 2018) and trade sales (VanWonen, 2026).
Revenue is generated from management fees and carried interest on multi-year fund commitments from institutional LPs (pension funds, sovereign wealth funds, insurance companies), with no public pricing disclosed. Distribution is conducted directly through a Capital Formation team led by Eric Lemer, supported by industry media presence and conference participation. Underlying technology is limited to standard fund-administration tooling (Juniper Square investor portal, DocuSign, Zendesk, Skilljar); the firm competes on local market presence, vertically integrated execution, contrarian cycle timing, and senior-team track record rather than on proprietary technology.
