Tensorway vs QuantumBlack, AI by McKinsey: overview
Tensorway
Tensorway split off in 2019 from a longer-running Alicante, Spain software house with roughly 25 years of prior delivery history, and now runs as a standalone practice of 20-50 deep learning architects, MLOps engineers, ML engineers, and QAs. Its service scope is unusually specific for a firm this size: an 11-step process covering challenge understanding, data profiling, feasibility study, and model validation, delivered by the same team that later builds whatever gets recommended. The firm frames its own value proposition directly, finding use cases with a real return, not the ones that just sound impressive.
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.
