BCG X vs Deloitte: overview
BCG X
BCG X launched in 2014 as Boston Consulting Group's technology build-and-design division, and it now runs over 3,000 technologists, data scientists, engineers, and designers across more than 80 cities worldwide. The distinction from a typical strategy-house AI practice is deliberate: BCG X is structured specifically to ship the generative AI and machine learning systems it recommends, not just hand off a roadmap and step away.
Deloitte
Deloitte's roots go 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 practice covers generative AI, agentic AI, and edge intelligence, and it runs a dedicated Deloitte AI Institute for published research. At this scale, AI advisory is one line of business inside an enormous global firm, not a purpose-built boutique.
