SPDG (Société anonyme de Participation et de Gestion)

SPDG was established in 1977 to manage the Périer-D'Ieteren family branch's interest in D'Ieteren Group. Catheline D'Ieteren controls the entity and its majority shares. The office preserves the historic holding while allocating capital outside the core position. The firm deploys through direct co-investments and SPVs. Asset classes include private equity, infrastructure, and venture. Confirmed positions include stakes in Outsight alongside Demeter Partners and BNP Paribas, LIFEPOWR with Noshaq and ROM InWest, and Cleverciti with EnBW New Ventures and KfW. It also participates in the Revive Impact Fund and the Green Neon wind-farm partnership with WATTS.green and I4B. Activity centers on Europe, with additional exposure in Western European real assets. SPDG lists 3494 million USD under management on internal records. The team maintains offices only in Brussels. Adjacent vehicles include the Fondation Périer-D'Ieteren and membership in Private Capital Belgium and the Family Business Network Belgium. In 2024 SPDG sold a 16.7 percent stake in D'Ieteren Group to Nayarit. SPDG operates as a certified B Corp with an explicit mandate to combine financial returns and measurable environmental outcomes. The structure keeps the strategic D'Ieteren holding inside the same legal entity that executes the external program, creating a direct link between legacy ownership and new capital deployment.
