QuantumBlack, AI by McKinsey vs KPMG: overview
QuantumBlack, AI by McKinsey
Before it was McKinsey's AI practice, QuantumBlack was a performance-analytics operation for Formula 1 teams, founded in 2009. McKinsey acquired it in December 2015 when it had around 45 people; it now runs out of London with staff across more than 40 offices globally and a reported headcount in the 1,001-5,000 range. That racing pedigree still shapes how the practice pitches itself: outcomes measured in specific numbers, not narrative claims about transformation.
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.
