Zero to One

Notes on Startups, or How to Build the Future

Peter Thiel

In 'Zero to One,' Peter Thiel argues that true innovation comes from creating something entirely new, going from 'zero to one,' rather than incrementally improving existing ideas. He emphasizes the importance of vertical progress through technology and the benefits of monopoly in driving innovation. Thiel also discusses the need for long-term planning, the importance of finding the right co-founders, and the power law in startup success. The book challenges conventional wisdom and encourages readers to think critically and aim big to build the future.

The Founders

The Story of PayPal and the Entrepreneurs Who Shaped Silicon Valley

Jimmy Soni

In 'The Founders', Jimmy Soni delves into the turbulent early days of PayPal, a company that would become one of the world's foremost payment platforms. With hundreds of interviews and unprecedented access to internal material, Soni chronicles the challenges faced by the founders, including bruising competition, internal strife, online fraud, and the dot-com bust of the 2000s. The book highlights how this group of entrepreneurs, often referred to as the 'PayPal mafia', went on to form, fund, and advise leading companies such as Tesla, Facebook, YouTube, SpaceX, and LinkedIn. It is a story of iteration, inventiveness, and the profound impact these individuals had on modern technology and entrepreneurship.

Elon Musk, Peter Thiel, Reid Hoffman, Max Levchin, David O. Sacks, Roelof Botha, Chad Hurley, Russel Simmons, and Jeremy Stoppelman are among those considered the “PayPal Mafia”. These are cofounders or early team members of PayPal who went on to found or invest in major tech companies like Yelp, Palantir, YouTube, Facebook, SpaceX, X, LinkedIn, Affirm, Airbnb, and others. In this episode, CJ is joined by Jimmy Soni, bestselling author of The Founders, which chronicles the early years of PayPal. He delves into some of the lesser-known aspects of PayPal's history. He sheds light on Peter Thiel's prediction of the dot-com collapse, why he advocated for the employment of Roelof Botha as CFO at the age of just 26, and his second-chance philosophy for hiring failures. The conversation covers PayPal’s “frenemy relationship” with eBay, how they convinced their users to advocate for them, and pivotal moments that influenced their IPO and sale. Tune in for unique insights into one of the most important "seed funds" in tech history.
