Since Portfolio was founded by Adrian Zackheim in 2001, it has emerged as a major force in nonfiction publishing for ambitious people. We connect readers with powerful ideas that inform and improve their lives, within the workplace and beyond. Portfolio authors are innovators, entrepreneurs, and experts who aren’t afraid to take risks and change the world. We strive to produce original books in fields such as technology, economics, entrepreneurship, biography, and investigative journalism, with a focus on educating and inspiring a new generation of innovative leaders.
Adrian Zackheim joined Penguin Group in September 2001 as Founder and Publisher of Portfolio. He then took on the additional challenge of starting Sentinel in April 2003. In 2018, he announced the addition of another new imprint to the group: The Optimism Press, in collaboration with Simon Sinek.
