Efficy operates a mid-market CRM platform built on Java, Go, PostgreSQL, and AWS infrastructure, with active investments in data maturity (Databricks, AWS Glue, silver/gold ETL layers) and AI feature development. The company is hiring across engineering, marketing, and sales simultaneously while managing legacy application decommissioning—a pattern typical of platforms transitioning from monolithic codebases toward cloud-native, data-driven architectures. Geographic expansion into Nordic and French markets signals scaling beyond the core European base.
