Aditum Arbo, zzp bedrijfsartsen

What Aditum Arbo, zzp bedrijfsartsen does

Aditum Arbo is a Dutch arts-makelaar (physician broker) founded in 2020 by Matthieu de Winkel and headquartered in Utrecht. The company connects self-employed occupational physicians (zzp-bedrijfsartsen) with Dutch employers seeking to fulfill their statutory occupational health obligations under the Arbeidsomstandighedenwet via the maatwerkregeling (customized arrangement), rather than through a traditional arbodienst. Its primary customer segments are large enterprise employers (groot zakelijke markt) and self-employed physicians seeking assignments, with secondary segments including MKB employers and employees seeking independent second opinions. As of May 2025, Maarten Hitman (formerly founder of De Nieuwe Arts) succeeded de Winkel as director. The company operates as a node within the broader Colbe network, a European health and wellbeing conglomerate serving approximately 1.3 million employees.

The operational backbone is Planningsagenda.nl, a digital scheduling, time registration, and reverse-billing platform used by both physicians and employer clients. Aditum Arbo handles administrative functions — invoicing, contract management, scheduling, intervention referrals — so freelance physicians can focus on clinical work. The platform integrates with MediSync for secure medical data exchange, Snelverwijspunt for intervention referrals within the Colbe ecosystem, and maintains ISO 27001, NEN 7510, and GDPR compliance. A complementary Vraag & Aanbod module displays anonymized physician profiles and open assignments, enabling direct match requests. Adjacent offerings include the Arbeidsomstandighedenspreekuur (AOS) for anonymous employee consultations and MediSync for delegated medical-data-request consent workflows.

The business model is brokerage-based managed services: Aditum Arbo charges facilitation fees for matchmaking and ongoing administrative support, with observed physician assignment rates of approximately €185–€190 per hour. The company leverages direct sales, content marketing, events (nascholingen), and its LinkedIn presence for distribution, covering all 12 Dutch provinces. Recent milestones include securing the OVAL second opinion contract (January 2025) and launching Wet DBA training events in mid-2025, both signaling expansion of both scale and service surface.
