QuantumBlack, AI by McKinsey vs Grid Dynamics: overview

QuantumBlack, AI by McKinsey

QuantumBlack began in 2009 as a performance-analytics agency for Formula 1 teams, then joined McKinsey in December 2015 at roughly 45 people. It has since grown into McKinsey's dedicated AI agency, run out of London with more than 40 offices worldwide and a LinkedIn-reported headcount in the 1,001-5,000 range. Few agencies on this list can point to a motorsport pedigree, and it still shows in how the practice talks about performance gains: specific, measured, and tied to a number rather than a narrative.

Grid Dynamics

Grid Dynamics has traded on Nasdaq as GDYN since March 2020, more than a decade after its 2006 founding. As of mid-2026 it reported roughly 4,838 personnel across the US, UK, the Netherlands, Mexico, Switzerland, and Central and Eastern Europe. AI advisory sits alongside its broader AI-powered digital engineering practice, and being publicly traded gives buyers financial visibility that most agencies on this list simply can't offer.
