Tensorway vs Grid Dynamics: 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.

Grid Dynamics

Grid Dynamics has traded on Nasdaq as GDYN since March 2020, more than a decade after its 2006 founding. As of mid-2026 it reported approximately 4,838 personnel across the US, UK, the Netherlands, Mexico, Switzerland, and Central and Eastern Europe, with the Netherlands presence putting a legal foothold inside the EU. AI-powered digital engineering is marketed as a core practice, and public-company status gives European enterprise buyers financial visibility most agencies on this list can't offer.
