Simon Sinek

Simon Sinek is a British-American author, speaker, and consultant known for his work on leadership, organizational culture, and motivation. He gained wide recognition for his concept of the "Golden Circle" and the idea that great leaders and organizations communicate by starting with "why" — their underlying purpose — rather than what they do.

His books include Start With Why, Leaders Eat Last, and Find Your Why, the latter co-authored with David Mead and Peter Docker as a practical workbook for individuals and organizations seeking to define their own sense of purpose. Sinek's talks and writing are widely referenced in business and leadership circles around the world.
