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. This episode was produced by Kerry Thompson, with music by Ramtin Arablouei. It was edited by Andrea Bruce, with research help from Katherine Sypher. Our engineers were Jimmy Keeley and Gilly Moon.

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. This episode was produced by Alex Cheng with music composed by Ramtin Arablouei.

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

As a college basketball player, Missy Park was lucky to grow up during the early era of Title IX, the 1972 law that created new opportunities for young women in sports. But in the years before Lululemon and Athleta, activewear for women was either ill-fitting or non-existent. So in 1989—with little experience in apparel or retail—Missy launched a female version of Nike. She sent out a mail-order catalog of running shorts, tights, and (at the last minute) sports bras, naming her company for the law that had opened doors for her to compete. Over the years, Title Nine kept "hitting singles," eventually growing into a $100 million business without ever taking outside investment. Today, Missy remains the sole owner.

While apple picking on a farm near Philadelphia, Abhi Ramesh learned that a massive amount of “misfit” produce goes to waste. He started running ads on Facebook to see if people would pay a discount for subscription boxes filled with twisted carrots and oddly-shaped squash. Demand was so strong that Abhi soon hired drivers on Craigslist to deliver produce around Philly from a rented warehouse. Four months in, Misfits Market had thousands of customers and landed $2 million in venture capital to expand. The pandemic turbocharged its growth and the business evolved into an online grocery store offering 1100+ items. Today Misfits Market operates in 48 states, and was most recently valued at $2 billion.

Dr. Dennis Gross was worried about putting his name on his skincare brand: would the word “gross” turn shoppers away? But Dennis and his wife and business partner, Carrie, realized that the key to the brand’s success lay in another part of the name – “Dr.” Dennis was able to use his experience as a dermatologist to develop effective skincare products, starting with a peel that could be done at home without causing blotchy skin. Later, the brand introduced an LED face mask, which looked like C-3P0 and lit up TikTok in glowing red and blue. In 2023, after being bootstrapped for much of its existence, the business was sold to cosmetics giant Shiseido in a deal worth $450 million.

In the early 2000s, one of the most popular pieces of software in the world was a free peer-to-peer file-sharing network called Kazaa. It was launched by two Scandinavian entrepreneurs, Niklas Zennström and Janus Friis, with the simple idea that internet users should be able to share anything with anyone in the world. After being knee-capped by lawsuits from the music industry, Niklas and Janus applied peer-to-peer technology to a new business: Skype, a service that allowed anyone with an internet connection and a microphone to talk to anyone else in the world… for free. At its peak, Skype connected hundreds of millions of global users, and in 2011, it was purchased by Microsoft for $8.5 billion.

After racking up thousands of dollars in fines, Chicago roommates Mark Lawrence and Jeremy Smith figured there had to be an easier way to park. So in 2011, they launched SpotHero as a peer-to-peer service, where people who lived near Wrigley Field might rent out their driveway on a game night. But that strategy wasn’t scalable, so SpotHero soon partnered with garages to sell excess inventory. Over the years, the startup faced intense pressure from investors to expand quickly and copy whatever the competition was doing. But Mark insisted on slow, strategic growth, and today, SpotHero is one of the largest digital parking platforms in North America, servicing about 300 cities.

During its formative years in the late 1990's, Paypal attracted an extraordinary group of young entrepreneurs, who then went on to build some of the best known companies in tech. They became known as The PayPal Mafia—and Max Levchin was one of the leaders. A computer genius from Soviet Ukraine, Max joined Peter Thiel, Elon Musk, Reid Hoffman and others as they grew PayPal into a massively successful online payment service. Along the way, they encountered almost every start-up challenge imaginable, including the emotional ouster of Elon Musk as CEO. After PayPal was acquired by eBay in 2002, Max couldn't sit still, so he launched a startup lab that eventually led to another successful fintech company: Affirm.
