QuantumBlack, AI by McKinsey vs Coherent Solutions: 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.
Coherent Solutions
Coherent Solutions was founded in 1995 by Igor Epshteyn in Minneapolis, Minnesota, and reported roughly 2,200 employees as of 2023. The company runs offshore development offices across Belarus, Bulgaria, Moldova, Mexico, Lithuania, Ukraine, Romania, Georgia, and Poland. Its core identity is software product development and advisory, with AI work delivered as part of that established practice rather than marketed as a dedicated AI unit.
