QuantumBlack, AI by McKinsey vs Capgemini Invent: 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.

Capgemini Invent

Capgemini Invent launched in 2018 out of Paris as the digital innovation, consulting, and transformation brand of the wider Capgemini Group, and it now employs somewhere between roughly 17,000 and 18,000-plus people across six continents depending on the source. It combines strategy work with data science and design under a single brand, treating AI as a component of digital transformation rather than isolating it as its own standalone practice.
