Consulting Firms Deploy AI Agents at Scale

McKinsey said it added 25,000 AI agents in under two years and plans to enable each of its 40,000 employees with at least one agent within the next 18 months. EY and PwC emphasize measuring agent quality and efficiency rather than raw counts; EY reported spending over $1 billion annually, building about 1,000 agents and deploying more than 100 internal AI applications.
