# SPDG SPDG is a Single Family Office based in Brussels, Belgium. ## Overview - **Organization type:** Single Family Office - **Headquarters:** Brussels, Belgium - **Region:** Europe - **Address:** Rue de Livourne 41, 1050 Brussels, Belgium - **Founded:** 1977 - **Assets under management:** ~$3.5B (Altss estimate) - **Website:** spdg.be - **LinkedIn:** https://be.linkedin.com/company/spdg-soci%C3%A9t%C3%A9-anonyme-de-participation-et-de-gestion ## Regulatory record - **Reports private funds:** No ## About SPDG was established in 1977 as the Périer-D'Ieteren family holding company, stewarding the fortune that one branch of the D'Ieteren family accumulated through its generation-spanning control of D'Ieteren Group. That group remains one of Europe's quiet industrial anchors—it is Belgium's dominant Volkswagen importer and the majority owner of Belron, the global vehicle-glass repair operation. Olivier Périer, a trained architect who co-founded the sustainable-design studio Urban Platform, took the CEO role in 2010 and has since reshaped SPDG from a passive family holding into an active principal investor. The office now deploys capital across direct co-investments, SPVs, venture-stage startups, and infrastructure assets. On the venture and growth side, SPDG has backed companies that sit at the intersection of hardware and climate-aware urban systems: Cleverciti, a Munich-based smart-parking sensor firm (alongside EnBW New Ventures, The Westly Group, and KfW); Outsight, a 3D spatial-intelligence company (alongside Demeter Partners, BNP Paribas Energy Transition Capital, Faurecia Ventures, and Safran Corporate Ventures); and LIFEPOWR, a Belgian distributed-energy startup (alongside Noshaq and ROM InWest). Infrastructure commitments include a co-investment in three French wind farms through the Green Neon partnership alongside WATTS.green and I4B - The Belgian Infrastructure Fund, reflecting a direct-ownership preference rare among European family offices. SPDG operates from Brussels with a lean team drawn from architecture, corporate M&A, and development finance. Senior advisor Michel Allé, a former CFO of Belgian Railways, and Stéphane Ryelandt, a former senior investment officer at BIO, bring deep infrastructure and emerging-market credit experience. In September 2024, the Périer-D'Ieteren branch sold a 16.7% stake in D'Ieteren Group to Nayarit, the vehicle representing the Nicolas D'Ieteren family branch, yielding a liquidity event that freed SPDG to intensify its direct-investment pace. The office also anchors a dedicated philanthropic foundation, Fondation Périer-D'Ieteren, which focuses on heritage conservation, education, and polar scientific research. What distinguishes SPDG structurally is its status as a single-family office that has deliberately severed the automatic reinvestment loop into the family's legacy industrial asset. By selling down a material stake in D'Ieteren Group, SPDG is now unambiguously a multi-asset allocator with a thematic climate-mobility mandate, rather than a dividend-dependent holding company. That decision, executed while the family's other branch retains strategic control of the listed entity, creates a dual governance architecture uncommon among European dynastic offices. ## Sectors - Mobility & Transportation - Energy Transition & Renewables - Circular Economy - ClimateTech ## People - Olivier Périer — Chairman of the Board and Chief Engagement Officer - Nicolas Périer-D'Ieteren — CEO - Denis Pettiaux — Permanent Representative to the Board of D'Ieteren Group ## Questions ### Who runs investment decisions at SPDG? Olivier Périer, SPDG's Chairman and Chief Engagement Officer since 2010, leads the investment function alongside CEO Nicolas Périer-D'Ieteren. The office blends operational experience—Périer spent his early career as an architect and sustainable-design entrepreneur—with a small team that includes former development-finance and M&A professionals. Denis Pettiaux represents SPDG directly on the board of D'Ieteren Group. ### Is SPDG structured as a single family office or does it operate more like a venture firm? SPDG is a single-family office managing the Périer-D'Ieteren branch's capital, not a multi-family office or third-party fund manager. However, its recent posture—direct co-investments, SPVs, and infrastructure equity alongside external partners—resembles a principal investment firm more than a traditional family holding company. The September 2024 partial exit from D'Ieteren Group further separates it from a dividend-dependent family vehicle. ### Does SPDG participate in fund commitments or only direct deals? SPDG does both. The office invests directly in startups, growth-stage companies, SPVs, and infrastructure projects, but also commits to funds. Team member Thibault Delmas, who joined in 2026, focuses specifically on private-markets fund investments, and SPDG previously co-invested in the Revive Impact Fund alongside Too'Gezer and Paverco. ### What investment stages does SPDG typically target? SPDG's strategy spans seed, venture, growth, and secondaries. In practice, its disclosed direct investments cluster around early- and growth-stage companies in climate-tech and mobility—Cleverciti, Outsight, and LIFEPOWR all raised SPDG's capital as part of post-seed or Series-A rounds alongside corporate and venture investors. ### How is SPDG related to D'Ieteren Group and the wider D'Ieteren family? SPDG represents the Périer-D'Ieteren branch of the D'Ieteren family, while D'Ieteren Group is the listed operating company controlled jointly by the Périer-D'Ieteren and Nicolas D'Ieteren branches. In September 2024, the Périer branch sold a 16.7% stake in D'Ieteren Group to Nayarit—the Nicolas D'Ieteren vehicle—reducing its direct economic overlap while maintaining board representation through Denis Pettiaux. ### Does SPDG maintain philanthropic structures, and how are they separated? SPDG operates the Fondation Périer-D'Ieteren as a separate philanthropic vehicle focused on heritage conservation, education, and scientific research. Olivier Périer also serves as an ambassador for the EPIC Foundation, which supports high-impact social nonprofits, and previously sat on the board of the International Polar Foundation. The foundation's activities are walled off from SPDG's for-profit investment portfolio. ## Related profiles - [The Losa Group](https://altss.com/profile/the-losa-group-bosch-gutierrez-family-office) - [Boyser](https://altss.com/profile/boyser-srl) --- Last updated: 2026-06-03T20:00:00.000Z Canonical page: https://altss.com/profile/spdg-perier-dleteren-family-office Maintained by Altss — https://altss.com — methodology: https://altss.com/methodology
