QuantumBlack, AI by McKinsey vs Exadel: 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.
Exadel
Exadel was founded in 1998 and is headquartered in Walnut Creek, California, with a reported headcount between 1,001 and 5,000 employees. It lists AI and data management as one of five core service areas alongside strategy consulting, digital experience, digital products, and managed services, so it reads as a broad technology agency rather than an AI-only specialist. Its more-than-25-year history is longer than nearly every other name on this list.
