STX Next vs Euristiq: 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.

Euristiq

Euristiq's Warsaw office keeps the company inside the EU's GDPR framework directly, useful for a UK buyer's data-processing terms, one part of a commercial footprint that also reaches Toronto alongside its Lviv engineering base since launching in 2016. The company is one of the newer firms on this list, with a shorter multi-year track record than the decades-old companies elsewhere in this review. Its public work spans general product development rather than one named vertical.
