Portfolio was founded in 2001 as the first dedicated business imprint within Penguin Group. It publishes distinctive hardcovers and trade paperbacks in the fields of management, leadership, marketing, business narrative, investing, personal finance, economics, technology, sales, entrepreneurship, and career advice. Three of its books have been finalists for the prestigious Financial Times / Goldman Sachs Business Book of the Year Award, and many have been named to best of the year lists by Business Week, Strategy & Business, 800-CEO-READ, and other organizations.

Some of Portfolio’s most noteworthy bestsellers include Purple Cow, Tribes, and Linchpin by Seth Godin; The Smartest Guys in the Room by Bethany McLean and Peter Elkind; The Search by John Battelle; Perfectly Legal by David Cay Johnston; The Art of the Start by Guy Kawasaki; Small Giants by Bo Burlingham; Pay It Down! by Jean Chatzky; Tough Choices by Carly Fiorina; The Starfish and the Spider by Ori Brafman and Rod Beckstrom; Wikinomics by Don Tapscott and Anthony Williams; The Go Giver by Bob Burg and John David Mann; The Back of the Napkin by Dan Roam; Talent is Overrated by Geoff Colvin; Start With Why by Simon Sinek; The Challenger Sale by Matthew Dixon and Brent Adamson; Street Fighters by Kate Kelly; Currency Wars by James Rickards; All the Devils are Here by Bethany McLean and Joe Nocera; Screw Business as Usual by Richard Branson; My Share of the Task by General Stanley McChrystal; Hatching Twitter by Nick Bilton; and The Frackers by Gregory Zuckerman.

Portfolio’s success in the United States has led to the creation of additional Portfolio imprints in other countries where Penguin Group is active, including the United Kingdom, India, South Africa, and Brazil. These sister imprints enjoy a rare degree of international collaboration on the books they publish together.
