Substack was founded to create an escape vehicle for writers: Chris Best and Hamish McKenzie imagined a world where writers didn’t have to rely on legacy publications or corporate advertisers, but could instead create a more direct and meaningful relationship with their audience. Despite early skepticism, Chris and Hamish were confident that many people would pay a few dollars a month to subscribe to their favorite newsletters, on subjects ranging from politics to sports to tech. Today, Substack has over 35 million active users, and while many of its offerings are free, a number of its content-creators make upwards of $500,000 a year.

This episode was produced by J.C. Howard, with music by Ramtin Arablouei.

Brad Baxter sidelined a promising career in the car industry to build a better cat litter box – an undertaking that embarrassed his kids and eventually prompted his wife to ask "what’s the endgame here?” That endgame turned out to be Litter-Robot, an automated self-cleaning litter-remover that helped propel Brad’s company, Whisker, to roughly $300 million in sales this year.

Cookware is a $73 billion global industry - awash in all kinds of pots and pans. Like, if you’ve ever cooked scrambled eggs, you've probably used a non-stick frying pan. They’re inexpensive and everywhere. But they’ve been dogged by complaints: many can’t handle high heat, like broiling or searing, and they scratch easily. So, when Danny Winer came across a new non-stick technology at a trade show overseas, he jumped on it, co-founding Hexclad with a buddy. Danny was convinced it could be adapted to the U.S. market - and be a hit. He was right! In just under ten years, Hexclad grew into a $500 million company.

What started as a design project for Stanford student Evan Spiegel quickly flourished into one of the most-used social media platforms in the world: Snapchat. It only took two years for Mark Zuckerberg to make a multi-billion offer for the company. But Evan turned it down — convinced of Snap’s potential to disrupt human communication in an even bigger way. And while Evan’s path has been anything but smooth, today Snap is valued at more than $13 billion, with ambitions beyond its hero mobile app.

When Wiliam Wang started selling flat-screen TV’s, he used a winning playbook: partner with an efficient manufacturer, cut out the middlemen, and price your product as low as you can. William used a similar strategy at his first company–making computer monitors–and he built it into a multimillion dollar business. But he wound up mismanaging it into the ground, and spent years working to pay off millions of dollars in debt. After surviving a catastrophic plane crash, William embarked on a new venture, Vizio, and returned to his “cut-out-the-middlemen” playbook to sell one of the world’s first internet-connected televisions. Today, Vizio is one of the top-selling TV’s in the US, and in 2024, sold to Walmart for $2.3 billion.
