ADR Institute

What ADR Institute does

ADR Institute (ADR Instituut) is a Dutch private professional training institute headquartered in Amsterdam, founded in 1996, that delivers accredited mediation, negotiation, and conflict resolution programs to professionals in the Netherlands. The company operates a curriculum of 12+ fee-for-service training programs built around three core pillars: the Beroepsopleiding (Legal) Mediator certification pathway, Harvard Method negotiation training (Excellent Onderhandelen), and HR-focused mediation skills (Mediationvaardigheden voor HR), plus specializations in business, labor, group, and transformative mediation. Its intellectual foundation combines the Harvard Negotiation Method (developed at Harvard Law School in the 1980s) with the Transformative Mediation model introduced by Bush and Folger in 1996; the firm notably hosts Carol Bloom, a transformative mediation authority trained directly by Bush and Folger, and a director (Maarten Bakker) trained at Harvard Law School.

The business model is dual-channel: (1) open-enrollment public courses priced per participant (€695–€3,250, with a 16-participant cap per session) offered at hotel/conference venues across seven Dutch cities, and (2) customized incompany (B2B) programs delivered at client organizations. Pricing is VAT-exempt and positioned as a professional services offering. Courses are accredited by NOvA, MfN, KNB, and NRTO, awarding mandatory PE/PO continuing education points required for lawyer and mediator registration, which creates a recurring-compliance demand layer.

ADR Institute reaches customers through a multi-channel marketing mix including SEO, content marketing, email newsletters, LinkedIn, Instagram, and free workshops/information evenings (live and online) used as top-of-funnel demand generation. The customer base spans four persona segments (HR professionals, practicing mediators, legal professionals, and general business professionals) with named enterprise clients including Shell, Rijk Zwaan, Mondriaan GGZ, MBO Amersfoort, BigBrother International, Oikocredit, Köster Advocaten, Oosterhof Holman, and Alexander Monro Ziekenhuis. The institute claims 25,000+ professionals trained cumulatively and a 9.2/10 average rating. The firm is privately held, founder/director-led, with no disclosed external investors, funding rounds, or M&A activity.
