Case Study: City of Zaanstad achieves €2.4 Million in savings over four years with Betty Blocks

City of Zaanstad Saves €2.4 Million over Four Years by Replacing Legacy System with Betty Blocks

The City of Zaanstad faced a 25-year-old legacy GWS system that blocked innovation and forced slow, centralized change across 300 municipalities. To take control of their software and implement a new vision for youth services, Zaanstad partnered with Ilionx and adopted the Betty Blocks no-code/low-code platform to build custom youth care and social services applications.

Using Betty Blocks, Zaanstad delivered a first live version in 10 days, cut time-to-market from 11 months to 1.5 months, and replaced seven legacy modules in three years. The new Betty Blocks applications boosted administrative efficiency by 40%, reduced backend developer needs from 10 to 4, saved €620,000 annually (about €2.4M over four years), and enabled continuous in-house development and municipal reuse.
