Tensorway vs ITRex Group: overview

Tensorway

Tensorway operates out of Alicante, Spain as the applied-AI arm of a longer-running Spanish software house with roughly 25 years of prior delivery history. Set up in 2019 as a standalone unit of 20-50 deep learning architects, MLOps engineers, ML engineers, and QAs, it documents every engagement against GDPR, HIPAA, ISO 9001, and ISO 27001, a compliance bar that matters directly to European buyers navigating data residency questions. Case work spans an agentic essay-evaluation tutor for an Australian e-learning client, a legal document automation agent reported at roughly 90% accuracy for a US law practice (per company website; independently unverifiable), and a deal-sourcing agent built for a Swedish private equity firm, a genuinely European client.

ITRex Group

ITRex has been based in Southern California since 2009, with public headcount estimates ranging from around 221 up to over 250 employees across three continents. The agency pairs AI and machine learning with data analytics and cloud computing, though its published delivery footprint centers on North America rather than Europe, which European buyers should factor into any data-residency planning.
