BCG X vs KPMG: 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.

KPMG

KPMG formed in 1987 from the merger of Peat Marwick International and Klynveld Main Goerdeler, with a lineage back to 1897, and runs today out of London. Headcount estimates land somewhere between roughly 251,875 and 275,288 depending on the reporting period. Its AI service line includes named products, aIQ and Mystro, aimed at AI transformation and digital labor optimization, a more productized service model than most Big Four peers, though the firm hasn't disclosed how much staff sits specifically inside AI.
