What Tri -plus does

Tri-plus is a privately held Dutch training and advisory bureau headquartered in Hoofddorp, Netherlands (Wijkermeerstraat 7, 2131 HB), focused on occupational health and safety (Arbeidsomstandigheden / Arbo) and works council (ondernemingsraad / OR) professionalization. The firm has operated for more than 20 years under the positioning "Het is puur mensenwerk" (It is purely human work) and serves Dutch organizations that are required to maintain a works council or to comply with the Arbowet. Its three core service pillars are: (1) Arbo services including Risk Inventory & Evaluation (RI&E), workplace research, and prevention-officer training; (2) OR training and advisory covering new-member training, professional OR development, and consultation/insteming process support; and (3) sustainable employability (duurzame inzetbaarheid) training aimed at reducing absenteeism and improving vitality. The technology stack is modest and largely partnership-built: a web-based OR-scan diagnostic and digital OR-workbook co-developed with ORnet, a mobile Corona RI&E module co-developed with FPSupport, a home-workstation e-learning built with Visser BV, and a differentiated Boeing 737 flight-simulator training experience offered with AATS. The business model is professional-services based, with publicly disclosed unit pricing of €345–€399 per participant (ex VAT) for scheduled one-day courses held in Hoofddorp, a 10% multi-attendee discount, and custom maatwerk training delivered on client sites (representing 75% of training volume per the firm's own commentary). GTM is consultative and sales-led, targeting HR advisors, Arbo advisors, and organization leaders via direct outreach, professional networks, content marketing, podcasts (OR-cast), and a concentrated event presence at OR Live!, the VGWM day, the Kennisfestival, and the OR & Zorg Congress. The customer base spans Dutch SMBs and mid-market enterprises across multiple industries, with documented work in healthcare (Envida) and pharmaceuticals (Teva); ownership, funding, and revenue are not publicly disclosed.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• HumanTotalCare: Major Dutch occupational health and safety group providing Arbo services, workplace health support and case management to employers. Comparable to Tri-plus on the Arbo advisory axis but as a large diversified incumbent with broader HR and case-management offerings.
• ArboNed: One of the largest Dutch occupational health service providers, offering Arbo advice, RI&E support and absenteeism case management to employers across the Netherlands. Overlaps with Tri-plus on Arbo advisory but operates at much greater scale and as a broad incumbent rather than a specialist OR + training firm.
• Schouten & Nelissen: Established Dutch training and development provider offering professional and leadership training programs for organizations. Comparable to Tri-plus on the corporate training delivery axis, but operating across many subject areas rather than specializing in Arbo and works councils.
• Sdu (Sdu Uitgevers): Large Dutch professional information and publisher focused on legal, HR and compliance content, including works council and Arbo topics. Comparable to Tri-plus on Dutch labor law expertise serving OR and HR buyers, but as a broad content and information incumbent rather than a training bureau.
• Zorg van de Zaak: Large Dutch provider of occupational health, absenteeism management and employer support services. Targets the same employer buyer as Tri-plus for Arbo and workplace wellbeing topics, but with a much broader service portfolio and national coverage.
• Loyalis: Dutch occupational health and workers' compensation service provider focused on sustainable employability and reintegration. Overlaps with Tri-plus on the sustainable employability and absenteeism theme targeting Dutch employers, but at significantly larger scale.

Direct peers

• Performa: Dutch HR and works council advisory firm that organizes the National OR & Zorg Congress with Tri-plus as partner. Comparable on the works council advisory axis, particularly for healthcare employers, making it a peer in the same niche.
• Visser BV (Ergonomics): Dutch ergonomics and workplace health consultancy that co-developed the Check je thuiswerkplek e-learning with Tri-plus. Directly comparable on ergonomic workplace advice and RI&E inputs targeting Dutch employers, with overlapping customer base.

Others

• ORnet: Dutch works council knowledge platform that partners with Tri-plus on the OR-scan and digital OR-workbook. A close ecosystem peer — overlapping target audience of OR members and professionals — though positioned as a content/knowledge network rather than an advisory bureau.
• FPSupport: Dutch supplier of RI&E and safety software that co-developed the Corona RI&E module with Tri-plus. Comparable via shared RI&E workflow and employer customers, but FPSupport sells the underlying software rather than advisory and training services.
