Loonium

What Loonium does

Loonium is a Dutch payroll and personnel administration service brand operating under parent company STYB Bedrijfsondersteuning BV, headquartered at Spoorstraat 2-4, 7271 CB Borculo, Gelderland, Netherlands. The company serves Dutch small and medium-sized employers with end-to-end payroll outsourcing (Loonium Plus at €11.25 per employee per month), AFAS Payroll optimization for clients holding their own licenses (Loonium op Maat at €8.00 managed / €4.50 self-service per employee per month), personnel administration, a digital learning platform (Loonium Leert at €2.75 per user per month, featuring TNO's DIX-scan and more than 700 learning items), and a government subsidy application service for BBL learners (Subsidie Praktijkleren, 7.5% commission on approved applications under no-cure-no-pay).

The technology stack is built natively on the AFAS ecosystem — AFAS Payroll for processing, AFAS Insite for the employer/employee web portal, and AFAS Pocket App for mobile self-service — supplemented by integrations with healthcare insurers, pension administrators, time-tracking systems (Dyflexis, Leza), and TNO's DIX-scan for well-being assessment within Loonium Leert. The Werkgeversportaal self-service employer portal handles mutations, in/out-of-service registrations, contract management, and one-click bank payments, while the Werknemersapp gives employees mobile access to payslips and leave requests.

With 7 employees and an exclusively Dutch operational footprint, Loonium operates as a focused niche payroll specialist rather than a scale-stage SaaS business. Its go-to-market is hybrid: relationship-driven direct sales with a single point of contact per client, supported by referrals (e.g., KNWU referring the Nederlandse Triathlon Bond), co-delivery partnerships with parent company STYB's OneFlow offering, and a self-serve component via the Loonium Leert platform. Revenue mechanics combine per-seat recurring subscriptions with a transaction-fee overlay on government subsidies; no external funding or institutional investors are disclosed in the source materials.
