About
McKinsey & Company is a New York City-based global management consulting firm — privately held as a partnership — providing strategy, operations, technology, and organization consulting to CEOs and C-suites of the world's largest corporations, governments, and institutions through approximately 40,000 professionals across 130+ offices in 70+ countries and approximately $16 billion in estimated revenue in 2024. Founded in Chicago in 1926 by James O. McKinsey, a University of Chicago accounting professor, the firm's modern identity was shaped by Marvin Bower (who joined in 1933 and led the firm from 1950-1967, establishing the partnership model, professional ethics standards, and global expansion that define McKinsey today). Global Managing Partner Bob Sternfels (reelected to a second and final three-year term in February 2024) oversees the firm through a challenging period that includes reputation headwinds from its opioid consulting work and global scrutiny of consulting industry practices. McKinsey's service capabilities span traditional strategy consulting through McKinsey Digital (digital transformation, analytics), QuantumBlack (AI and machine learning, acquired 2015), and McKinsey Technology (CTO/CIO advisory, technology strategy) — with over 7,000 employees in digital and technology roles and approximately 40% of 2024 projects estimated to be AI-related. McKinsey's "State of AI in 2025" report found that organizations now mitigate an average of four AI-related risks (versus two in 2022) and that AI high performers (6% of survey respondents) attribute 5%+ EBIT improvement to AI, with AI agents increasingly deployed as virtual coworkers rather than passive research assistants.
