What FOSAG does

Koninklijke OnderhoudNL, operating under the KvK-registered entity in Waddinxveen with headquarters at Tielweg 16 in Gouda, Netherlands, is a royal-chartered Dutch trade association (ondernemersorganisatie / brancheorganisatie) serving specialist contractors in property maintenance, renovation, restoration, insulation, painting, glazing, and industrial metal conservation. Its membership spans at least seven sector verticals — Schilders, Glas, Vastgoed, Totaal, Restauratieschilders, Industrieel, and ZZP (self-employed professionals) — and it acts as the collective bargaining counterparty for sector-wide collective labor agreements (CAO) and pension arrangements. The organization is governed as a non-profit and is not publicly listed; its primary legal identity is Koninklijke OnderhoudNL with KvK 40409386.

The association's product and service portfolio is built around member support rather than proprietary technology. Core offerings include OnderhoudNL Trainingen (covering technical skills, safety, mentorship, management, communication, RGS, and climate and energy transition), Ledenadvies advisory on CAO, pensions, RI&E, wage guidance (Loonkompas), and leave arrangements, the Vakwerk Plusgarantie quality certification, the Indexreeks Onderhoud en Verduurzaming market intelligence tool, and the MijnOnderhoudNL member portal. It also operates the 'Wij onderhouden van Nederland' campaign platform for talent attraction and runs partner benefits, a member magazine, webinars, and an events agenda. Underlying technology is limited to standard website, portal, and campaign-platform infrastructure; no proprietary AI, APIs, or SDKs are disclosed.

The business model is membership-based: the association acquires members through its 'Word lid' channel and supports them with CAO representation, training, advisory, certification, and commercial-acquisition tools in exchange for membership dues and training/certification fees, which are not publicly disclosed. Go-to-market relies on content marketing via the onderhoudnl.nl website, events and webinars, a monthly magazine, the 'Zoek een bedrijf' public directory, and the national recruitment campaign. Headcount is reported at 6 employees, indicating a lean administrative back office that delivers association services primarily through its governance role and contracted training/partnership delivery rather than large in-house operations.

Direct peers

• Vlakglas Nederland: Dutch association for the flat glass sector. Directly relevant because 'Glas' is one of OnderhoudNL's seven primary segments; both organizations serve overlapping member companies in glazing, restoration, and property maintenance.
• NOA (Nederlandse Ondernemersvereniging voor Afbouwbedrijven): Dutch trade association for finishing and interior-construction companies (painters, plasterers, tilers, ceiling installers). Most directly comparable to OnderhoudNL as both represent Dutch SMB contractors in adjacent finishing trades and provide CAO, training, and advisory services.
• VVVF (Vereniging van Verf- en Drukinktfabrikanten): Dutch association of paint, coating, and printing ink manufacturers. Complementary counterpart to OnderhoudNL: where OnderhoudNL represents painting contractors, VVVF represents the upstream paint suppliers they purchase from, creating an industry-ecosystem parallel.

Broad incumbents

• Techniek Nederland: Dutch trade association for the technical installation sector (electrical, mechanical, plumbing, climate installation). Comparable business model (CAO negotiator, training provider, lobbyist for SMB installers) and overlapping member base in property maintenance, particularly in energy-transition topics.
• Bouwend Nederland: Largest Dutch employers' association for the construction and infrastructure sector. Comparable as a sector-wide trade body providing CAO, lobbying, and member services, but operating at a broader (infrastructure/utility/new-build) level rather than specializing in property maintenance like OnderhoudNL.
• MKB-Nederland: Confederation of Dutch SMEs and trade associations. Comparable as an advocacy and support organization for small businesses across all sectors; OnderhoudNL's SMB member base overlaps strongly with MKB-Nederland's constituency.
• VNO-NCW: Largest Dutch employers' confederation representing ~185 branch associations and 40,000+ companies. Operates as a broad umbrella in which OnderhoudNL and similar trade associations participate; comparable membership-based advocacy and lobbying function at a national scale.
