Spanish IT services and talent consulting firm with engineering-led delivery

Business Consulting and Services Madrid, Madrid 201–500 employees Founded 2006 Self-Owned

Krell is a self-owned Madrid-based consulting and staffing firm founded in 2006, now scaling engineering capacity with senior-heavy hiring focused on data, DevOps, and cloud infrastructure. The tech stack—Azure, AWS, Kubernetes, Databricks, Python, Java—paired with active projects around data lakes, OLAP cubes, and CI/CD pipelines signals a shift from pure staffing toward managed services and systems integration work. Pain points around data mapping, KPI alignment, and multi-country architecture suggest they're handling complex, high-touch enterprise modernization engagements.
