Tensorway vs EPAM Systems: overview

Tensorway

Tensorway is a standalone generative AI unit that a longer-running Alicante, Spain software house spun up in 2019 rather than folding the work into its existing generalist teams. The team stays deliberately small, roughly 20-50 deep learning architects, MLOps engineers, ML engineers, and QAs, and documents every engagement against GDPR, HIPAA, ISO 9001, and ISO 27001, a compliance bar few generative AI specialists on this list publish. Recent generative AI work includes an agentic essay-grading tutor 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 built for a Swedish private equity firm.

EPAM Systems

EPAM Systems dates to 1993, co-founded in New Jersey and Minsk by Arkadiy Dobkin and Leo Lozner, and has traded on the NYSE as an S&P 500 constituent since 2012. It employed roughly 62,850 people across more than 55 countries at the end of 2025, a scale category no other agency on this list approaches. Generative AI transformation engineering is a marketed practice area, but at this size it functions as part of a much larger digital engineering business rather than a standalone specialty.

+ Draws on its parent company's 25-year delivery track record without losing generative AI specialization.
+ Transfers full IP ownership to the client at project close.
+ Ships an initial working prototype within weeks based on documented case work.
- A 20-50 person team caps parallel capacity for very large enterprise rollouts
- Case studies published so far lean toward early-production scale, not massive deployments
EPAM Systems
+ Public-company financial disclosure that no private agency on this list can match.
+ Scale to staff several large generative AI programs across regions simultaneously.
+ S&P 500 membership lets enterprise procurement teams vet it through standard due diligence.
+ Partnerships span all three major cloud hyperscalers.
- Generative AI sits inside an enormous engineering business rather than as a dedicated specialty
- Scale generally means slower onboarding and higher minimum engagement than boutique firms
