Information Technology & Services Capelle aan den IJssel, South Holland 201–500 employees Privately Held

Conxillium Group builds software for municipal governments across the Netherlands, Belgium, Germany, Curaçao, and Aruba, serving millions of citizens daily. The stack reveals a transition underway: React + Next.js frontend, Spring Boot + Java backend, Kubernetes orchestration on AWS — a move toward cloud-native architecture reflected explicitly in active projects around AWS CDK/CloudFormation and scalable application redesign. Pain points cluster around legacy system rebuilding, 24/7 uptime demands, and a shift from project-based to product-oriented teams, suggesting they're consolidating multiple acquired products into platform services.
