BCG X vs Deloitte: overview
BCG X
BCG X is the technology build and design division of Boston Consulting Group, launched in 2014 and headquartered in Boston, Massachusetts. It brings together more than 3,000 technologists, data scientists, engineers, and designers across 80-plus cities, positioned specifically to build and ship AI and generative AI solutions rather than just advise on them. That combination of BCG's strategy pedigree with an in-house technical build team is the unit's core pitch to enterprise clients who don't want to hand a strategy deck to a separate vendor.
Deloitte
Deloitte was founded in 1845 in London and is now the largest professional services network in the world by revenue and headcount, employing approximately 470,000 people as of 2025. Its AI and Insights practice covers generative AI, agentic AI, and edge intelligence, backed by the Deloitte AI Institute for research and thought leadership. At this scale, AI consulting is one service line within an enormous global professional services firm, not a dedicated boutique.
