What is STX Next?
STX Next is one of Europe's largest Python software houses, founded in 2005 and headquartered in Wrocław, Poland, with 600+ engineers. The firm's ML strength lies in operationalising models within complete software systems — engineering the full software ecosystem required for ML to function reliably in production. In 2026, STX Next has increased emphasis on MLOps, deployment automation, and long-term model maintainability, making it a strong choice for teams that need ML embedded in larger Python-based products.
STX Next was founded in 2005 and is headquartered in Wrocław, Poland. The firm employs 600+ people and works primarily with clients in Financial Services, Healthcare & Life Sciences, Media & Entertainment, Logistics & Supply Chain, SaaS & Technology sectors. Its primary differentiator is: Europe's largest Python shop — ML is embedded in full-stack Python systems with MLOps, not delivered as an isolated model.
