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.
