Tensorway vs LeewayHertz: overview
Tensorway
A longer-running Alicante, Spain software house with roughly 25 years of prior delivery history spun up Tensorway as a dedicated AI unit in 2019 rather than folding AI work into its existing generalist teams. The unit stays small on purpose, roughly 20-50 deep learning architects, MLOps engineers, ML engineers, and QAs, and every engagement is documented against GDPR, HIPAA, ISO 9001, and ISO 27001 standards, a compliance bar most agencies on this list don't publish. Named work includes an agentic tutor that grades essays for an Australian e-learning company, 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 for a Swedish private equity firm.
LeewayHertz
LeewayHertz has operated from San Francisco since 2007, though its ownership changed in September 2024 when The Hackett Group acquired the company. That's relevant to anyone evaluating long-term strategic direction, since the agency now answers to a larger consulting parent. Public employee counts have also shifted, from roughly 300 in earlier reporting to about 182 by mid-2026, worth confirming directly given the volume of content marketing the agency publishes relative to its actual team size.
