Simon began his career in the world of advertising, working with top agencies in New York. His academic background in cultural anthropology from Brandeis University, combined with his experience in marketing, laid the foundation for his deep understanding of human behaviour and motivation. He rose to prominence after developing The Golden Circle concept, which explores the “Why, How, and What” of leadership. This idea, first introduced in his 2009 bestseller ‘Start With Why’, struck a chord with leaders across the globe. His 2009 TED Talk, “How Great Leaders Inspire Action”, became one of the most-watched TED Talks of all time, catapulting him into the international spotlight.
In recent years, Simon has continued to shape conversations around leadership and culture. His book ‘Leaders Eat Last’ explores how organisations can build trust and safety to encourage high performance. More recently, he released ‘The Infinite Game’, which challenges businesses to adopt a mindset focused on sustainability and long-term success over short-term gains. He is also the founder of The Optimism Company, a consultancy and learning platform dedicated to helping people and teams unlock their potential. Simon remains a sought-after speaker for some of the world’s most influential companies, including Microsoft, Google, and the U.S. military.
Organisations hire Simon because he offers more than motivational rhetoric—he delivers frameworks that are actionable, thought-provoking, and grounded in a clear sense of purpose. Whether he’s speaking to CEOs or emerging leaders, Simon equips audiences with the tools to lead with authenticity and resilience. His ability to connect deeply with people, backed by proven thought leadership and global influence, makes him one of the most trusted voices in high-performance leadership today.
