TBI Holding

What TBI Holding does

TBI Holdings B.V. is a Rotterdam-headquartered, steward-owned Dutch holding company that consolidates 26 wholly-owned operating companies organized into three business segments: Techniek (technical engineering and installation services through subsidiaries including Croonwolter&dros, Eekels Technology, Comfort Partners, Giesbers InstallatieGroep, Soltegro, and WTH Vloerverwarming); Bouw & Ontwikkeling (construction and real estate development through J.P. van Eesteren, ERA Contour, Hazenberg, Koopmans Bouwgroep, Synchroon, HEVO, MDB, Nico de Bont, GeWOONhout, Rutges Vernieuwt, and Voorbij Prefab); and Infra (civil infrastructure through Mobilis, Struijk, Voorbij Funderingstechniek, and Voton). The group employs approximately 7,000 FTE skilled professionals and runs 1,001+ active projects, including high-profile Dutch public-sector works such as the Binnenhof renovation.

The holding's sole shareholder is Stichting TBI, a foundation structure that imposes steward-ownership discipline — prioritizing long-term societal value, reinvestment of profits, and continuity of the operating companies over short-term shareholder returns. Revenue is generated almost entirely through project-based construction, engineering, and infrastructure contracts awarded to the relevant subsidiary on a per-project basis, delivered via direct enterprise sales to Dutch government, municipalities, and large commercial clients. The company also operates four purpose-aligned funds (TBI Studiefonds, TBI Klimaattrein, TBI Praktijkfonds, TBI Zebra) supporting education, climate, craftsmanship, and sustainable mobility initiatives.

TBI serves exclusively the Dutch market and explicitly positions the combination of technical, construction, and infrastructure capabilities under one concern as a differentiator that allows it to undertake nationally significant projects few competitors can deliver in-house. No proprietary technology platform, software products, or AI/ML capabilities are disclosed beyond a recent magazine feature on AI; the business is fundamentally execution-driven rather than technology-product-driven, with the primary intangible asset being the steward-owned brand and the structural integration of its 26 subsidiaries.
