Simon Sinek is a writer, speaker, and teacher who spends most of his time asking one simple question: why.

He has built a career helping people and organizations put purpose at the center of how they work and lead.

Sinek was born in Wimbledon, London, in 1973 and spent his childhood moving between Johannesburg, London, and Hong Kong before his family settled in the United States. He graduated from Northern Valley Regional High School at Demarest in New Jersey in 1991, and growing up in several countries gave him an early curiosity about people, culture, and what drives human behavior.

He went on to study cultural anthropology at Brandeis University, which fit that curiosity well. After a brief spell studying law at City, University of London, he realized the legal path was not for him and moved into the world of advertising and communications. In New York he joined major agencies such as Ogilvy and Euro RSCG, working on brand and marketing campaigns for corporate clients.

Over time he became less interested in selling products and more interested in the deeper beliefs behind them, which led him to start his own small consultancy, Sinek Partners. At one low point he has described falling out of love with his work, and the search for a clearer sense of purpose in that season later shaped the ideas he would share with others.

That search turned into his first book, Start with Why, published in 2009, and a related TEDx talk about how great leaders inspire action. The talk spread widely and helped make the idea of the Golden Circle, starting with why before how and what, a practical tool people could use to think about leadership, branding, and motivation. The talk has remained one of the most watched in the TED library, introducing huge audiences to his view that people are inspired from the inside out.

He followed with Leaders Eat Last, which looks at trust, biology, and the kind of workplace where people feel safe enough to take risks for one another. Drawing on research about brain chemistry, stories from the military, and examples from modern companies, he argues that effective leaders create a circle of safety in which people can focus on solving problems instead of protecting themselves.

With Together Is Better, an illustrated fable, he offered a shorter and more playful story about change, courage, and finding work that matters. Wanting to make his ideas practical, he then coauthored Find Your Why, a hands on guide that walks individuals and teams through exercises to define their own purpose statements and bring those words into everyday decisions. In The Infinite Game, he argues that business and leadership are not contests to win once but ongoing games that reward long term thinking, strong relationships, and a just cause.

Away from the page, Sinek has spent years working with organizations of all sizes, from startups to global companies and branches of the United States military. His client list over the years has included technology companies, consumer brands, nonprofits, and public sector agencies that invite him in when they want to rethink culture and leadership. He has served as adjunct staff with the RAND Corporation, taught strategic communications at Columbia University, and continues to speak at events for people who want to lead with more clarity and care.

Today he is based in New York, though his work often has him on the road. In recent years he has helped launch projects focused on optimism and reform, from a publishing imprint that amplifies other voices to a learning company and initiatives that explore better models for leadership in business and public service. Across all of his projects he returns to the same themes: optimism, service, and the belief that everyday people can do meaningful things when they understand their why and take care of the people around them.
