Tensorway vs LeewayHertz: 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.
LeewayHertz
LeewayHertz has operated from San Francisco since 2007, though ownership changed in September 2024 when The Hackett Group acquired the company. Employee counts have shifted from roughly 300 in earlier reporting to about 182 by mid-2026. No European office is publicly listed, so EU clients would contract with a purely US-based (now Hackett Group-owned) entity.
