How I Built This with Guy Raz

Amy Errett had a successful career in finance and venture capital before taking a leap into an entirely new business: hair color. When her wife complained about the indignities of coloring her hair at home, Amy realized the sector was ripe for a makeover. At age 56, she dove into the minutiae of dyes and developers, launching her own formula in 2013, and naming it after her daughter. Madison Reed’s early successes were marred by a management meltdown, when Amy had to break with three of her co-founders—an experience she describes as one of the most difficult of her life. Today Madison Reed is available in thousands of stores across the US, and runs nearly 100 of its own salons. This episode was produced by Sam Paulson with music composed by Ramtin Arablouei.

Crumbl may be a cookie business – but Jason McGowan turned it into a fast-growing restaurant chain by building it like a tech startup. He and co-founder Sawyer Hemsley meticulously A/B tested the recipe, launched a delivery app early on, and went viral with weekly drops of wild new flavors like bubblegum and Almost Everything Bagel. In just eight years, Crumbl has opened over 1,000 stores, and has dominated the cookie conversation on social media, with more TikTok followers than Starbucks, Domino’s, and Taco Bell combined.

Long before he became famous as the sharp-tongued TV personality who launched the careers of pop stars, Simon Cowell was a rebellious teenager who dropped out of school and started his career in the mailroom at EMI. After a failed business left him nearly bankrupt, he found success by zigging where others zagged—initially by selling hit records based on TV shows like Power Rangers and WrestleMania. Eventually Simon got behind the TV camera himself, where his brutally honest feedback on shows like American Idol and The X Factor made him a household name. Today, through his company Syco Entertainment, Simon continues to discover new talent. His latest challenge: an upcoming Netflix show where he’ll try to build a boy band from scratch.

Long before founding Torchy’s Tacos, Mike Rypka was a troubled teenager trying to outrun his own self-destruction. Growing up around addiction and falling into heavy drug use himself, Mike’s future looked bleak—until he got clean and found refuge in kitchens. Cooking gave him structure, purpose, and eventually, a career. After years working in restaurants and corporate kitchens, Mike decided to take a risk on something smaller: a food truck on a street corner in Austin. In 2006, he launched Torchy’s with nothing but a dream, a fiery logo, and a menu full of bold flavors. That humble truck became the start of something much bigger. Today, Torchy’s is a national chain with more than 130 locations and annual sales topping $300 million. And through all of it, Mike has remained sober—more than three decades and counting.

As a Harvard squash player, Will Ahmed discovered his game improved when he focused on things like sleep, diet, and time spent recovering from training. He was convinced that granular health and heart data would become invaluable to other athletes if it could be bundled into a wearable wrist strap. In 2012, Will founded WHOOP, and after three years the company launched its first model, with Lebron James and Michael Phelps as advocates. But WHOOP struggled to gain traction with mere mortals, and spent years overhauling its business model and fending off big name competitors. Eventually it became one of the most popular wearables on the market, with a valuation well above $3 billion.

As a newly arrived immigrant from Turkey, Hamdi Ulukaya learned to be resourceful, determined, and even stubborn when he needed to be. All those traits would serve him well as he began to navigate the hairpin turns of building a yogurt business from the ground up. In 2005, Hamdi was running a small feta cheese business in upstate New York when he happened upon a piece of junk mail that would change his life: an ad for an abandoned yogurt factory...$700K, as is. He knew if he could get his hands on it, he could bring a new kind of dairy product to the U.S.—the thick, creamy yogurt he’d grown up eating in the mountains of Turkey. With the help of a local bank, Hamdi bought the factory, and sales grew so quickly that he could barely keep up. A few years later, some bad business decisions nearly pushed the company into bankruptcy, but today, Chobani is one of the most popular yogurt brands in the U.S; and Greek-style yogurt has become a staple of the dairy aisle.

Rick Steves spent the summer after high school backpacking through Europe on two dollars a day—sleeping on the floor, sneaking into museums, and subsisting on a diet of bread and jam. When he came home, he found people were hungry for tips on how to visit Europe on the cheap, so he began teaching classes, and was soon hawking a self-published guidebook out of his car. Eventually, he started leading minibus tours and hosting a travel show on Public TV, steadily growing his business even though he was giving away most of his content. His no-frills approach to travel has persisted as a powerful brand, with 70 guidebooks, an ever-popular travel show, and—in 2024—an annual revenue of $120 million.

After falling in love with the gelato shops of Buenos Aires, Josh Hochschuler came home to Dallas with a bold idea: bring authentic Argentine gelato to the U.S. He raised $600,000 from friends and family and opened a gelato shop called Talenti. The product was a hit - but the retail model wasn’t. Faced with mounting losses, Josh shut down the store and moved into a warehouse to pivot to wholesale. With time, tenacity, and a now-iconic clear jar, Talenti became a national sensation, and in 2014, was acquired by Unilever. Today, it’s the best-selling gelato brand in America.

On a trip to Las Vegas, Chris Riccobono found himself wearing the same J.Crew shirt over and over; it was the only dress shirt he had that looked good untucked. All of his other button-downs were too long and looked sloppy. His buddies all said they had the same problem, so Chris decided to seize the opportunity and launch UNTUCKit with a friend. Keeping his day job as a GE salesman, he embarked on a crash course in how not to make a shirt. Thousands of defective button-downs later, UNTUCKit hit its stride, and the big fashion brands began to copy the untucked look. In 2020, UNTUCKit came within inches of a lucrative acquisition, then nearly went bankrupt, but today has grown into a thriving brand. This episode was produced by J.C.

The dashboard in your car – the interface on your Zoom screen … many of the products we interact with every day were created with the collaborative software Figma. Figma is a kind of Google Docs for design, created by Dylan Field and Evan Wallace after they won a Thiel fellowship in 2012. Dylan was just 20 when he became CEO. The only other job he’d had before that….? was college intern. He eventually figured out how to manage his team, and grew the company enough to attract a 20 billion dollar acquisition bid from Adobe. The deal fell through, but Figma continued to grow, and recently filed for an IPO. This episode was researched and produced by Kerry Thompson with music composed by Ramtin Arablouei.
