Leading through transformation is difficult. Doing it with hundreds of thousands of people is something else entirely. Kathryn McLay knows what that takes.

As former President and CEO of Walmart International and Sam's Club, McLay led one of the world's largest and most complex organizations through a defining period of change. Responsible for operations across 18 countries, more than 500,000 associates, and millions of customers each week, she helped align global teams behind a shared strategy while navigating disruption, accelerating growth, and driving execution at extraordinary scale.

On stage, McLay makes transformation tangible. Rather than offering theories, she shares the leadership principles she relied on to align hundreds of thousands of people around a common goal, execute through uncertainty, and sustain performance at extraordinary scale. Audiences leave better equipped to lead change inside their own organizations—whether they're responsible for fifty people or fifty thousand.

Funny, provocative, and endlessly engaging, Harvard Business School professor Leslie John has a gift for making people rethink what they thought they knew about human behavior. An award-winning behavioral scientist, she studies the choices people make in conversation and why our instincts about trust and influence are often spectacularly wrong.

John is the James E. Burke Professor of Business Administration at Harvard Business School, but her work starts with questions that are anything but academic. How much is too much to share? Why can asking questions be more powerful than making an argument? Her forthcoming book, Revealing: The Underrated Power of Oversharing, turns one of our most familiar social anxieties into a surprising case for greater openness.

On stage, John brings the energy of a great storyteller to the rigor of a Harvard researcher. Through humor and counterintuitive findings, she gives audiences a fresh way to understand the people around them and practical ideas for becoming more effective leaders and communicators.

The AI race won't be won by the companies building the models. It will be won by the companies that know how to put them to work. Few leaders understand that better than Bill McDermott.

As Chairman and CEO of ServiceNow, Bill leads one of the Fortune 500's fastest-growing technology companies and is helping define how the world's largest organizations put AI to work. Under his leadership, ServiceNow has become a leader in enterprise AI, connecting people, data, and workflows to drive transformation at scale. Previously, as CEO of SAP, he led one of the most successful chapters in the company's history, cementing his reputation as one of the technology industry's most admired executives.

On stage, Bill offers a CEO's perspective on the biggest technology shift of our time. Drawing on decades leading global software companies, he shares how organizations can harness AI to accelerate growth, lead through disruption, and build businesses prepared for what's next.
