Rotterdam: 20,000 applications a week instead of 5,000
The city of Rotterdam built an RBZ portal and a medical system on Mendix: 40+ apps, 20,000 applications a week, and regulatory changes shipped in 3 days.

The challenge
Handling business applications drowned in paper forms, emails and no automation. Rigid healthcare software couldn’t keep up with changing guidelines and was patched with giant Excel sheets.
What Mendix did
An RBZ portal and a medical system were built on Mendix by small teams. 40+ apps replaced paper, email and Excel with one controlled process, and the first version of the support portal was ready in 2 weeks.
Results
What it means for your business
Public institutions still handle applications on paper and email, and patch critical processes with Excel. Mendix lets you build e-service portals and registries in weeks, auditably and GDPR-compliant, updated for legal changes in days, not months.
This is an edition of our “Powered by Mendix” newsletter. Every two weeks, one real deployment with metrics and context.
