Tensorway vs EPAM Systems: overview

Tensorway

Every project Tensorway ships is built to GDPR, HIPAA, ISO 9001, and ISO 27001 standards, which is a stricter bar than most AI vendors on this list volunteer to meet. The unit was carved out in 2019 from a longer-running Alicante, Spain software house with roughly 25 years of prior delivery history, and it kept its team narrow and specialized: deep learning architects, MLOps engineers, ML engineers, and QAs, with roughly 20-50 people total working on AI specifically rather than a slice of a much larger generalist staff. Documented work includes an agentic essay-grading tutor for an Australian e-learning company, a legal document automation agent reported at around 90% accuracy for a US law practice (per company website; independently unverifiable), and a deal-sourcing agent built for a Swedish private equity firm.

EPAM Systems

EPAM Systems traces back to 1993, founded jointly in New Jersey and Minsk by Arkadiy Dobkin and Leo Lozner, and has been an S&P 500 constituent trading on the NYSE since 2012. By the end of 2025 the company employed roughly 62,850 people across more than 55 countries, a scale that puts it in an entirely different category from any other firm on this list. AI transformation engineering is one of its marketed practice areas, but at this size it operates as part of a much larger digital engineering and cloud transformation business rather than a standalone specialty.
