QuantumBlack, AI by McKinsey vs IBM Consulting: 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.
IBM Consulting
IBM Consulting's history runs back to 1991, and it operates today out of Armonk, New York, with a global headcount near 160,000. The 2021 rebrand from IBM Global Business Services signaled a shift in focus, and its AI work now leans heavily on IBM's own watsonx platform alongside decades of enterprise client relationships. For a company already standardized on IBM infrastructure, that's a genuine advantage; for one that isn't, it's a real limitation worth weighing before a shortlist gets built.
