About STX Next

STX Next describes itself as Europe's largest Python-focused digital engineering partner and has operated since 2005. Clutch records AI development at 55% of its service mix and generative AI at a further 15%, so AI is the majority of the work rather than a line item, and the published tooling around it, Python, Django, AWS, Azure, Snowflake and Databricks, is data platform engineering.

The evidence base is the strongest in this ranking: 4.7 from 102 Clutch reviews, the largest review count on this page. A 4.7 across 102 reviews says more than a 5.0 across 12, and we ranked it on that basis rather than on score alone. Pricing is published end to end: a $50,000 minimum, $50 to $99 per hour, and projects typically between $50,000 and $750,000.

Our verdict

STX Next is the firm to pick when the AI work is inseparable from backend and data platform engineering and you want the deepest evidence base on this page before committing: 4.7 across 102 Clutch reviews is a more reliable signal than a 5.0 across a dozen, and the price picture is published from minimum to typical project size. It is a Python engineering partner first, though. Nothing in the record names an agent framework, an evaluation suite or tracing, and Clutch's aggregated feedback flags frontend capability trailing backend strength plus timezone coordination friction, both of which matter for a user-facing agent. That, together with a $50,000 floor that rules out pilot-sized work, keeps it third behind two firms with narrower agent specialization.
