STX Next vs Tallium: overview
STX Next
STX Next started in Poznań, Poland in 2005 around Python engineering specifically, and has since broadened into AI, data engineering, and cloud work while keeping delivery centers in Poland and Mexico and adding offices in the UK, Germany, and the US. That UK office is a staffed local presence rather than a virtual sales address, useful for a British buyer who wants an in-market contact point for a Python-heavy or data-engineering-heavy build. Its Python-first technical culture is a real specialization most general outsourcing vendors on this list don't claim.
Tallium
Every other company on this UK-facing list quotes engagements privately; Tallium, founded in Kyiv in 2012, simply posts its rate on GoodFirms instead: $25-$49 per hour, backed by a 5.0-star rating across more than 40 verified reviews. That transparency makes genuine cost comparison possible before a first call, a real advantage for a UK buyer sizing up a budget before committing to a discovery process. Its boutique scale suits single-team engagements rather than the multi-hundred-person programs a firm like SoftServe or Ciklum can staff.
