Information Technology & Services Hilversum, Noord Holland 201–500 employees Founded 1980 Privately Held

SLTN is a 40-year-old Netherlands ICT firm operating at mid-market scale with 201–500 staff and a consulting-led service model across healthcare, government, and corporate clients. The tech stack reveals a hybrid legacy-and-modern shape: mature enterprise platforms (Oracle suite, IBM WebSphere, DB2) sit alongside cloud-native adoption (Kubernetes, OpenShift), signaling migration from monolithic SOA toward containerized workloads. Active hiring skews heavily toward senior engineers and data roles—indicating scaling of integration complexity and data governance rather than pure headcount growth.
