What Synthra does
Synthra is a Dutch occupational health service provider (arbodienst) headquartered in Rotterdam, founded in 2011, operating across the Netherlands with a team of 40+ employees. The company delivers absence management, prevention, occupational health, mediation, reintegration, training and advisory services to Dutch employers, anchored in regulatory expertise covering the Arbowet, WIA, and Ziektewet frameworks. Service offerings include RI&E (risk inventory and evaluation), ERD WGA & ZW own-risk-bearer administration, and certified-arbo advisory.
The technology backbone consists of a proprietary product suite built around the Symbios absence management platform, supplemented by ZiektewetFlex (sickness benefit application handling), WIA Dossier Check (WIA assessment preparation), ADS-R (reintegration documentation), and the Arbo Data Vault (secure client data infrastructure). These systems embed employer-side workflows for sickness registration, case routing, and reintegration tracking, and represent the operational layer through which Synthra delivers its services. No external platform dependencies or third-party AI integrations are disclosed.
The business model combines direct employer subscriptions for the Symbios-based management layer with case-based professional fees for company-doctor consultations, mediation, reintegration support, and ERD WGA & ZW administration. Customers are Dutch employers of varying sizes, acquired through direct sales with no disclosed channel partnerships. No funding rounds, external investors, or revenue disclosures are available, and the firm has operated as a private B.V. (besloten vennootschap) on an internally funded basis since incorporation.
