QuantumBlack, AI by McKinsey vs Coherent Solutions: 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.

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 service identity is software product development and advisory, with AI work delivered as part of that established practice rather than marketed as a dedicated AI service line.
