What FOJA Groep does

FOJA Groep is a privately held, family-owned Dutch holding company founded in 1995 by Fons Jans and headquartered in Apeldoorn, Netherlands. It consolidates five wholly-owned operating subsidiaries — Hamer (technical installations, 500+ employees, 4 locations in NL and BE), Voets Installaties (pump, tank and chemistry installations, acquired 2023), ContrAll (engineering, project management and inspection), FBS (commercial vehicle repair, hydraulics, rental and sales) and JANS (technical staffing and training) — to deliver turnkey technical projects from design through maintenance to enterprise clients in the BeNeLux region across five verticals: Industry, Utility, Mobility, Fuel, and Communication & ICT.

The group's core technology is the physical design, installation, inspection and maintenance of technical installations — electrical, climate, process, storage, fuel, fire-safety and data-center systems — supported by in-house prefabrication capability. Hamer is the primary technical-installation brand, while ContrAll provides engineering and inspection, Voets covers fuel and tank infrastructure, FBS supports mobility/workshop fit-out and commercial vehicles, and JANS supplies technical labor and training. There is no proprietary software platform or AI component disclosed in the input; value delivery rests on integrated project execution, certified CO2 management (Level 3, September 2023) and compliance credentials (Horizontaal Toezicht convenant with the Belastingdienst, signed March 2026).

The revenue model is B2B professional services, with project-based quoting and no publicly disclosed pricing. Go-to-market is direct enterprise sales led by account managers who scope and coordinate cross-subsidiary delivery from A to Z under FOJA's holding-level oversight. Named enterprise logos include Total, McDonald's, Hiab, KPN, NL-DC, EG, Arriva, Gasunie, Equinix, OpenText, PPG, Syntus, AECOM, ARN, Ericsson, Allego and Croda, spanning automotive, telecom, data centers, transport, chemicals, infrastructure and EV charging. FOJA's stated strategy is to let subsidiaries focus on core execution while the parent provides finance, marketing, HRM, innovation and sustainability shared services, enabling cross-selling and bundled turnkey delivery.
