ITRex Group vs Grid Dynamics: overview

ITRex Group

ITRex has operated out of Southern California since 2009, with public headcount estimates ranging from about 221 to over 250 across three continents depending on the source. The firm pitches itself on the combination of artificial intelligence, data analytics, and cloud computing rather than AI in isolation, which means clients get a partner comfortable with the data infrastructure an AI system needs before it can be built at all. That breadth costs some specialization depth compared to AI-only boutiques, but it removes a common integration headache.

Grid Dynamics

Grid Dynamics has traded on Nasdaq under the ticker GDYN since March 2020, more than a decade after its founding in 2006. As of mid-2026 the company reported approximately 4,838 personnel spread across the US, UK, the Netherlands, Mexico, Switzerland, and Central and Eastern Europe. AI-powered digital engineering is positioned as a core practice rather than a bolt-on offering, and being publicly traded gives enterprise buyers a level of financial visibility most vendors here don't provide.
