IT Services and IT Consulting Munich, Bavaria 11–50 employees Founded 2000 Privately Held

Simple System operates a B2B e-procurement platform launched in 2000, running on a polyglot stack (Spring Boot, PostgreSQL, Elasticsearch, MongoDB, Kafka, Kubernetes) that suggests a maturing backend capable of handling high-volume catalog and transaction workloads. Current hiring focuses on sales and marketing roles alongside backend engineering—a pattern consistent with scaling go-to-market rather than product innovation, and their pain-point list (sales workflow bottlenecks, lead scoring, customer feedback integration) confirms they're optimizing GTM and retention rather than building new features.
