QuantumBlack, AI by McKinsey vs PwC: overview
QuantumBlack, AI by McKinsey

Its AI service offering lives inside a broader digital transformation and technology consulting practice rather than standing on its own, consistent with PwC's identity as a diversified professional services firm first, an AI specialist second.
