Deri Llewellyn-Davies is a strategist and advisor who has worked with over 330 boards, known for helping leaders cut through complexity and think clearly under pressure. Raised in a rural Welsh village, he developed an early sense of community that shaped his approach to leadership, which he later carried into high-stakes environments. He is the creator of the Strategy on a Page methodology, a #1 bestseller that has helped thousands of founders scale with purpose. Beyond the boardroom, Deri has tested human limits through extreme challenges, including climbing six of the world’s highest mountains, completing the Marathon des Sables, and competing in Ironman races—experiences that informed his Ultra States framework, which reframes performance as the management of mental and physiological states rather than relying on motivation alone. As a speaker and podcast guest, he shares practical, systems-level insights on leadership, performance, and burnout, grounded in both advisory work and real-world experience under pressure.
