Deloitte vs ITRex Group: overview
Deloitte
Deloitte's history runs back to 1845 in London, and it has grown into the largest professional services network in the world by both revenue and headcount, employing roughly 470,000 people as of 2025. Its AI and Insights service line covers generative AI, agentic AI, and edge intelligence, backed by a dedicated Deloitte AI Institute that publishes research. At this scale, AI advisory is one service among many inside an enormous global firm, not a purpose-built boutique offering.
ITRex Group
ITRex has operated out of Southern California since 2009, and public headcount estimates range from around 221 up to over 250 employees across three continents. The agency deliberately bundles AI advisory with data analytics and cloud computing services rather than offering strategy in isolation, checking whether a client's data infrastructure can actually support the roadmap before recommending one.
