Deloitte vs Exadel: 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.

Exadel

Exadel was founded in 1998 and is headquartered in Walnut Creek, California, with a reported headcount between 1,001 and 5,000 employees. It lists AI and data management as one of five core service areas alongside strategy consulting, digital experience, digital products, and managed services, so it reads as a broad technology firm's service catalog rather than an AI-only specialist. Its more-than-25-year history is longer than nearly every other name on this list.
