QuantumBlack, AI by McKinsey vs Exadel: overview

QuantumBlack, AI by McKinsey

QuantumBlack started life in 2009 as a performance-analytics operation for Formula 1 racing teams before McKinsey folded it into the firm in December 2015, when the unit numbered around 45 people. Today it runs McKinsey's dedicated AI services out of London, across more than 40 global offices, with headcount reported in the 1,001-5,000 range. Its service catalog spans strategy, data engineering, and model deployment, with the motorsport origin still shaping how it frames results: specific numbers, not narrative claims.

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 firm's service catalog rather than an AI-only specialist. Its more-than-25-year history is longer than nearly every other name on this list.
