BCG X vs Deloitte: overview
BCG X
BCG X is Boston Consulting Group's technology build and design arm, launched in 2014 out of Boston and now staffed by more than 3,000 technologists, data scientists, engineers, and designers spread across 80-plus cities. Where a lot of strategy-house AI practices stop at the recommendation, BCG X is built specifically to also ship the generative AI and machine learning systems it proposes, which is the core reason enterprise buyers hire it over a pure advisory firm.
Deloitte
Deloitte dates to 1845 in London and 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 spans generative AI, agentic AI, and edge intelligence, and it maintains a dedicated Deloitte AI Institute for research and thought leadership. At this scale, AI advisory is one service line inside an enormous global firm, not a purpose-built boutique agency.
