Who They Work With
Python-heavy teams that need senior engineers now, with AI built into how the work is delivered and reviewed.

Our Take
The clearest AI evidence is a product rather than a service line: the Use Case Management Tool built with appliedAI in Munich, which inventories a company's AI use cases against EU AI Act obligations—useful in itself, and a sign the team has read the regulation.
The Cambium Group engagement is the most concrete thing published on the site: Claude Code configured with three convention files, eleven codified review rules, an eight-phase command with a human approval gate, an isolated worktree per ticket and around 38 pull requests so far.
Note what that engagement is, though. It is AI applied to how STX Next writes software, not a system shipped to Cambium's customers, and the client-facing machine learning—wind turbine blade performance—sits inside a wider cloud and infrastructure engagement with the client anonymized.
The weaker fit is a buyer who wants a measured production AI system: this is a Python house running since 2005 at 250+ people with an AWS Advanced Tier partnership, strongest as a team extension that now builds with AI rather than as a model-delivery specialist.
Key strengths
- EU AI Act work is real and named: the use-case inventory and risk-assessment tool built with appliedAI for compliance and portfolio oversight
- The Cambium engagement documents the delivery method in unusual detail—conventions, eleven codified rules, an eight-phase pipeline with an approval gate, one worktree per ticket
- Twenty years of Python delivery at 250+ people, with an AWS Advanced Tier partnership and named clients across research instruments, pharmacy and fintech
Good to know
- The strongest AI evidence is AI inside their own delivery, not a system shipped to a client's users—ask which production AI system they built and who operates it
- The machine-learning work in the wind-energy engagement is one part of a cloud and infrastructure program, with the client anonymized—ask for the modeling detail
- Rates here come from third-party listings rather than STX Next—confirm pricing, and whether you are buying a team extension or a fixed-scope build
