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.

SPDG leverages the Périer-D'Ieteren family's seven-generation industrial network in European automotive and infrastructure circles, its membership in Private Capital Belgium and the Family Business Network, and its direct advisory relationships. The office has repeatedly co-invested alongside corporate venture arms—Faurecia Ventures, Safran Corporate Ventures, EnBW New Ventures—suggesting deal flow originates through deep industrial partnerships rather than auction processes.

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.

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.

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.

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.

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.
