Trigonus

What Trigonus does

Trigonus B.V. is a privately held Dutch ICT interim management and consulting firm, founded in 2001 and headquartered at Koninginneweg 8 in Hilversum. The firm deploys approximately 20 senior consultants on-site at client organizations to deliver six interconnected service lines: project management (portfolio planning through implementation), consultancy, architecture, process and IT design, data migration, and implementation management. Trigonus specializes in three sectors — Telecommunications, Energy/Utilities, and Government/Public Sector — and explicitly markets domain knowledge in process and product development as a core asset. The named customer base includes virtually every major Dutch telecom operator (KPN, T-Mobile, VodafoneZiggo, Odido, Tele2), major utilities (Vattenfall, Enexis, Alliander, Gasunie, Liander, Engie), and a wide range of ministries and agencies (BZK, Defensie, Buitenlandse Zaken, Belastingdienst, DUO, ProRail, Openbaar Ministerie, RDW, KNMI), plus financial-services and healthcare clients (Robeco, GGZ Ingeest, AbbVie). Deliveries include multi-year harmonization programs, smart-meter rollouts, ERP migrations, and lead-architecture roles on national forensic and HR systems.

The firm operates a sales-led, partner-originated go-to-market with no proprietary software product and no public pricing — engagements are quote-based professional services delivered by consultants billable on assignment. The technology stack is methodological rather than proprietary: the team holds credentials including TOGAF, IREB, PRINCE2, ITIL, ISTQB, Scrum, PSPO, Scaled Agile, Lean Green Belt, and TMap Suite. Process mining at client sites uses third-party tools such as UiPath (Enexis). Trigonus achieved NEN 4400-1 / SNA certification in 2026-07, formalizing compliance with Dutch employment agency and payroll quality standards relevant to public-sector tenders. Distribution is single-country, with all named engagements inside the Netherlands, and delivery is supported through partnerships with Conclusion (system integrator) and The Data Migration Company. The company is led by partners Will Vogel (Commercial and General Management, ex-Atos) and Geert Jan Meijer (Consulting), and operates without external institutional investors, parent company, or subsidiary structure.

Scale indicators3 records

Recent moves5 records

Expansion highlights5 records

Broad incumbents

• Accenture Nederland: Accenture is a broad global incumbent in strategy, consulting, digital, and technology services with a substantial Netherlands practice across telecom, energy, and government — directly overlapping with Trigonus's verticals at the upper end of project scale.
• BearingPoint Nederland: BearingPoint is a European-origin management and technology consultancy with a Dutch practice serving telecom, energy, and public-sector clients — competing with Trigonus on programme management, transformation, and ICT architecture mandates.
• Atos Nederland: Atos is a broad-incumbent global IT services firm with significant Dutch telecom (KPN) and government presence — Will Vogel, Trigonus's partner, was previously Business Unit Manager at Atos. Atos competes for the same RFPs Trigonus bids on but at much larger scale.
• Capgemini Nederland: Capgemini is a global management and IT consulting incumbent with strong Dutch telecom and public-sector practices. It competes with Trigonus on project management, business analysis, and digital transformation mandates but offers a far broader offshore and nearshore delivery model.
• Deloitte Nederland: Deloitte's Consulting practice in the Netherlands competes with Trigonus for business analysis, programme management, and digital transformation work in telecom, energy, and government — operating as a broader incumbent with cross-industry consulting depth.

Direct peers

• CGI Nederland: CGI's Dutch operation is a direct IT consulting peer serving telecom, energy/utilities, and government clients with project management, business analysis, and systems integration services that overlap substantially with Trigonus's offerings.
• Conclusion: Conclusion is a leading Dutch IT services and consulting group with deep public-sector and telecom exposure. Trigonus already partnered with Conclusion as system integrator on the Ministry of Foreign Affairs HR modernisation, making Conclusion both a partner and the closest Dutch direct competitor in Trigonus's verticals.
• Magnus Red: Magnus is a Dutch interim management and ICT consultancy that places senior consultants on client projects across telecom, energy, and government. It is the closest head-to-head competitor in Trigonus's interim-management niche within the Dutch market.

Emerging players

• The Data Migration Company: The Data Migration Company collaborates with Trigonus on data migration projects at Gasunie. It is a niche Dutch specialist in data migration — directly comparable to Trigonus's data migration service line.

Regional players

• KPN Consulting (Strategy & Innovation): KPN's internal consultancy and innovation units engage external ICT consultants including Trigonus. As a major Dutch telecom client and occasional competitor for in-house transformation work, KPN sits at the interface of customer and competitor.
