Sinek’s first TED talk in 2009 became one of the most popular of all time, with 43 million views.




Sinek’s interview on millenials broke the internet in 2016, generating over 200 million views in the first month.


Sinek’s work focuses on leaders and companies with the capacity to inspire. He identifies patterns to how they think, act and communicate, and the environments in which people operate at their best, to transform corporate culture. His concept of “why,” as first popularized through his 2009 TED Talk, is based on inspiring people to do the things that inspire them so that, together, each of us can change the world for better. Sinek has more recently explored the difference between finite and infinite games, and how organizations struggle when their leaders play with a finite mindset in an infinite game.




Sinek teaches leaders and organizations how to inspire people. He has partnered with Ernst & Young to develop products and services to help companies transform. He is an adjunct staff member of the RAND Corporation, one of the most highly regarded think-tanks in the world. He is also active in the arts and in the non-for-profit world (Sinek prefers to call it the for-impact world).

“No one has done more to put the ‘why’ back into business. Sinek should be compulsory reading for leaders.”
