Simon Sinek

Simon Sinek is a British-born American author and speaker known for popular frameworks about leadership, trust and organisational purpose. Start with Why develops the Golden Circle: organisations usually describe what they do and how they do it, while influential leaders begin by communicating why the work matters. Sinek uses companies, social movements and public figures to argue that a clear sense of purpose can shape loyalty, decision-making and long-term behaviour. The 15th Anniversary Edition returns to the same core work with updated framing; it is not a separate empirical study or a wholly different book. The Golden Circle is a practical communication model, not a universally validated law of psychology, and the success stories selected for illustration do not prove that purpose alone causes business performance.
