BCG X vs Deloitte: overview
BCG X
BCG X launched in 2014 as Boston Consulting Group's technology build and design division and now runs more than 3,000 technologists, data scientists, engineers, and designers across 80-plus cities. What differentiates its service model from a typical strategy-house AI practice is the follow-through: BCG X is structured to actually ship the generative AI and machine learning systems it recommends, folding a build service into what would otherwise be a pure advisory engagement.
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.
