Simon Sinek

Simon Oliver Sinek, born on 9 October 1973 in Wimbledon, is an American author and inspirational speaker on business leadership. He is best known for writing about leadership, purpose, teams, and optimism, with books that include Start with Why in 2009 and The Infinite Game in 2019. His public work belongs to the modern era of business speaking, where books, conferences, digital learning, and widely watched talks all help carry ideas about work and leadership to a broad audience.

Sinek’s early life was international. His mother is of Hungarian Jewish descent, and as a child he lived in Johannesburg, London, and Hong Kong before his family settled in the United States. He graduated in 1991 from Northern Valley Regional High School at Demarest in Bergen County, New Jersey. He went on to earn a BA in cultural anthropology from Brandeis University, then studied law at City, University of London. That mix of places and studies sits in the background of a career focused on how people think, communicate, and organize themselves.

Before becoming widely associated with leadership writing, Sinek worked in advertising. He began his career at the New York ad agencies Euro RSCG and Ogilvy & Mather, then launched his own business, Sinek Partners. He has described himself as an “optimist,” a word that also appears in later parts of his work. He has been an instructor of strategic communications at Columbia University and an adjunct staff member of the RAND Corporation, roles that connect his speaking and writing to communication, strategy, and institutions.

His first major book, Start with Why: How Great Leaders Inspire Everyone to Take Action, was published in 2009. The next year, his talk “How Great Leaders Inspire Action,” arising out of that book, became one of the most-viewed TED talks. Sinek spoke at TEDx conferences several times beginning in 2009, and he also spoke at the UN Global Compact Leaders Summit in 2016. His later books include Leaders Eat Last: Why Some Teams Pull Together and Others Don’t in 2014, which appeared on the bestseller lists of The Wall Street Journal and The New York Times; Together Is Better in 2016; Find Your Why in 2017; and The Infinite Game in 2019.

In November 2018, Publishers Weekly reported that Sinek would start Optimism Press, a new imprint of Penguin Random House. He later launched The Optimism Company, a digital learning platform. His words continue to connect with readers because they are direct about work, trust, purpose, and honesty. One of his lines captures that plain-spoken tone: “Life changes for the better when we realize that we don’t have to know everything and we don’t have to pretend that we do.”
