ITRex Group vs Infosys: 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.

Infosys

Infosys was founded in 1981 and is headquartered in Bengaluru, India, employing approximately 330,429 people worldwide as of March 2026. The company delivers a comprehensive suite of enterprise AI development services alongside automation, cybersecurity, and advanced data analytics, and its wholly-owned subsidiary Infosys Consulting, founded in 2004 and headquartered in London, adds a dedicated strategy and consulting layer on top. At this scale, AI development is one thread inside one of the world's largest IT services organizations rather than a boutique specialty.
