How I Built This with Guy Raz

David Heath and Randy Goldberg saw an opportunity to disrupt a long dormant—and arguably boring sector...socks. They met at a startup in their 20s, each already had their own side hustles before they hatched a plan to launch a business together. Randy and David didn’t initially intend to get into the sock business, but in 2011, David read that socks are the most requested clothing item a...

Water is all around us–quite literally, there is enough water in the air we breathe to meet all of humanity’s needs and then some.

Cody began manufacturing these ‘hydropanels’ with his Arizona-based company SOURCE in 2014, and today they’re used in more than 50 countri...

When you consider the risk of doing business, it doesn’t get much bigger than starting a car company: competition is formidable, startup costs are in the billions, and very few people believe you can pull it off. That’s the massive challenge RJ Scaringe walked into in 2009, when he launched his truck and SUV company, Rivian. To add to the risk, RJ wanted to build fully electric vehicles while attr...

In 2009, Sarah Kauss had a well-paying job in real estate development, but she was itching to do something more. On a hike in Tucson with her mom, she got an idea for a business while swigging warm water from a metal thermos: Why not design a water bottle that kept cold things cold and hot things hot, but was also beautiful to look at? Just six years after launch, S'well reportedly made $100 milli...

In 1973, the first Men's Wearhouse opened in Houston with little fanfare, but by the mid-80s, George Zimmer managed...

In 2003, David Baszucki wanted to go viral. He had already sold a company that made educational software, and now he wanted to build something with mass appeal; with build-your-own avatars and myriad opportunities for users to compete and connect online. So in 2006, he and his co-founder Erik Cassel launched Roblox, a platform where you can play millions of different games, set in a wide...

In 2014, friends Polina Veksler and Alex Waldman went clothes shopping at a major department store. To Polina’s surprise, Alex’s options were quite limited, and tucked away in one of the store’s less-traveled upper levels: the ‘plus-size’ section.  This unnerving realization that women could have such completely different shopping experiences at the same store drove Polina into research mode....

When Saeju Jeong moved from South Korea to the U.S. in his mid-20's, he barely knew anyone, didn't speak much English, and had only $5,000 in savings.

This came with the territory, as David worked on designing dozens of products for Apple over the years – including their first computer mouse back in 1980.  Since then, David and his firm, IDEO, have helped all sorts of companies design new products.

In this episode, Guy sits down with Colin Rosenblum and Samir Chaudry, or better known as YouTubers Colin and Samir—a pair of creators who create content for other creators. (We know, pretty meta.)

She called it “The Financial Diet.” This week on How I Built This Lab, Guy talks with Chelsea about how...

When Leah left her IBM job to start coding the service, the peer-to-peer economy was still i...

When Donnel Baird was a child, his parents would regularly use the oven to heat their Brooklyn apartment ⁠— a dangerous and energy-inefficient practice that’s unfortunately not unique to New York City. As an adult traveling the country with the Obama for America campaign, Donnel saw countless homes and apartments wasting power and jeopardizing resident safety because of dated infrastructure. He fo...

While she was a student at business school, Shazi Visram ran into an old friend—a new mother of twins. The friend confided she felt like a bad mom because she had no time to make her kids healthy meals.

People told her she was crazy to take on Gerber, but she convinced dozens of friends a...

According to the 2022 report from the Intergovernmental Panel on Climate Change (IPCC), the world needs to cut carbon emissions drastically to avoid the worst effects of global warming.

In addition to reducing emissions, we also need to remove 6 to 10 billion tons of carbon dioxide from the atmosphere each year by 2050.  This week on How I Built This Lab, Guy talks with Ja...

Jimmy Fallon may talk like a comedian, but he thinks like a restless entrepreneur. In addition to his day job as host of The Tonight Show , he runs a TV production company, writes best-selling children’s books, and creates products you never knew you needed, like all-day pajamas and “hands high” jerseys that show the name of your favorite team in the armpit. As a kid, Jimmy was obsessed...
