Preworxs BV

What Preworxs BV does

Preworxs BV is a Dutch prefabricated installation systems manufacturer headquartered in Goes, Zeeland. Founded in 2017 and operating from a factory and office at Scottweg 4 in Goes (relocated May 2024), the company engineers, produces, and delivers modular installation modules — primarily SKIDs (pre-assembled technical frames integrating heat pumps, ventilation, water heaters, floor heating distributors, and controls), prefabricated shafts, electrical distribution systems (elektra spinnen), ventilation ductwork, and complete plug-and-play technical rooms. Production is BIM-driven, with each module parametrically designed, factory-tested, CE-certified, and delivered just-in-time to Dutch construction sites. The product family spans the Indak-skid for pitched roofs, GevelSKID for facades, Plafondskid for healthcare ceilings, HomeEngine for all-electric residential installations, and the Inventum MODUL-AIR SKID developed with manufacturer partner Inventum.

Preworxs serves four primary customer segments in the Dutch market: installation contractors (installateurs), modular builders, equipment manufacturers (fabrikanten), and prefabricated construction companies (prefab bouwbedrijven), with named deployments across residential, healthcare, hospitality, education, and renovation projects. The company monetizes through project-based, quote-driven sales of custom and standardized modules, embedding engineering and BIM consultation into project pricing. Distribution combines direct enterprise sales with two scaled channels: Wasco (wholesale distribution to Dutch installers) and Inventum (OEM-bundled sales through Dutch wholesalers). The firm holds ISO 9001 (DEKRA, June 2023) and ISO 14001 certifications, has been recognized as an FD Gazelle for three consecutive years (2023, 2024, 2025), and won the Techniek Inclusief Award 2024 for inclusive hiring practices.

The company is privately held, with 12 employees as of the latest data, and operates exclusively in the Netherlands. Reported operational metrics include over 1,000 cumulative installation systems placed, up to 80% on-site labor savings, 90% packaging reduction, 80% lower on-site CO2 emissions, and roughly 25% shorter construction time on maximum-prefab projects. Ownership is founder/management-led (Algemeen directeur Mark-Jan Koldijk, Financieel directeur Leander van Reeven, Commercieel manager Johan Bogert), with no disclosed venture or private equity investors.
