Good morning. McKinsey is best known as a consulting powerhouse, but its quieter distinction is as a leadership factory—a point I explore in my latest piece for Fortune. No other organization has minted more sitting Fortune 500 chiefs, with a global roster that includes Alphabet’s Sundar Pichai, Citigroup’s Jane Fraser, and Allianz’s Oliver Bäte. The tally stands at 18 current Fortune 500 CEOs and 28 worldwide.
For companies serious about succession, the question isn’t just why McKinsey has this record, but how to emulate it to strengthen internal pipelines.
The firm’s method is as rigorous as it is intentional, more than a dozen former and current McKinsey alumni told me. From day one, new consultants rotate across industries, geographies, and functions, adapting on the fly and mastering unfamiliar businesses. They are expected to deconstruct sprawling problems, craft solutions, and win over skeptical executives—often while still in their 20s. That early exposure to high-stakes decision-making accelerates judgment and builds the confidence boards later crave in C-suite leaders, according to consultants-turned-CEOs.
Equally critical is McKinsey’s culture of constructive dissent. Hierarchy matters less than ideas, and consultants are trained to challenge assumptions and present counterarguments, even to senior partners or client CEOs. This discipline, debating until the best idea survives, teaches future leaders to welcome scrutiny, pressure-test their own reasoning, and make tough calls with limited information.
