STX Next

STX Next is a Poland-based software and AI/data engineering firm founded in 2003. The company employs 500+ engineers split between delivery centers in Poland and Mexico. They position themselves as Python specialists—a foundation built over 21 years—and have expanded into AI, data strategy, and cloud solutions. The firm claims 1000+ completed projects, with recent work targeting financial services, industrial, and technology sectors. Their pitch centers on "AI-augmented" development using tools like Claude Code and GitHub Copilot, framed as a way to accelerate deployment without sacrificing quality.

Services and capabilities

STX Next organizes its offerings around five pillars: AI & Data Strategy, AI Development, Cloud & DevOps Solutions, Product Design & Strategy, and AI-Augmented Software Development. The AI & Data Strategy work involves pattern detection and predictive modeling to extract business value from existing data sets. Cloud & DevOps offerings focus on cost reduction and operational efficiency. Product Design & Strategy includes user research, UX/UI, and interface design.

The company emphasizes its use of agentic engineering tools and proprietary frameworks built for regulated industries. No specific technology stack is detailed on the public site, though Python is mentioned as a core competency. Case studies hint at work with machine learning, LLMs, and predictive maintenance platforms, but technical depth is sparse in the source material.
