BCG X vs KPMG: 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.

KPMG

KPMG formed in 1987 from the merger of Peat Marwick International and Klynveld Main Goerdeler, with a lineage tracing 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 cited. Its AI service line includes named products, aIQ and Mystro, aimed at AI transformation and digital labor optimization, which is more productized than most Big Four peers, though the firm hasn't disclosed how much staff sits specifically inside the AI practice.
