ITRex Group vs Grid Dynamics: overview
ITRex Group
ITRex has been based in Southern California since 2009, and public headcount estimates range from around 221 up to over 250 employees across three continents. The agency pairs generative AI and machine learning with data analytics and cloud computing rather than offering AI in isolation, which means clients get a partner who can handle the data plumbing a generative AI system needs before the model itself gets built. That broader scope costs some depth relative to generative-AI-only specialists but avoids a common integration bottleneck.
Grid Dynamics
Grid Dynamics has traded on Nasdaq as GDYN since March 2020, well over 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. Generative AI is marketed as part of a broader AI-powered digital engineering practice, and public-company status gives enterprise buyers financial visibility most agencies on this list can't offer.
