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 array of virtual worlds. You can adopt a pet, escape from jail, build and run your own restaurant, or solve a murder mystery; you can even create games of your own. During the start of the pandemic in 2020, half of the kids in the US were keeping in touch via Roblox, and today, the company is worth over 28 billion dollars.

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. She found that about 70% of women in the U.S. wear a size 14 or larger, but less than 20% of clothing is made in those sizes. Meanwhile, much of the double-digit-sized clothing available is fast fashion: not particularly well-fitting or built to last.Alex and Polina decided to create Universal Standard: a clothing brand where size was irrelevant – where any woman could shop and ask herself, “do I like this?” – not “does this come in my size?”This week on How I Built This Lab, Guy and Polina discuss the $100 billion opportunity to serve women of all sizes, as well as the challenges that come with building a size inclusive clothing brand.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

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. Today, he's the CEO of Noom, one of the most popular weight loss/wellness apps in the U.S. Inspired by his late father—a doctor who criticized the profession for treating people only after they got sick—Saeju and his co-founder built their first fitness product in 2007. Several pivots later, they arrived at Noom, an app that carefully tracks what you eat, how you sleep and when you're stressed out. Noom has hinted it may go public this year—if so, the valuation could be as high as $10 billion.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Sam and Mariah Calagione started dating in high school, and have been on a wild ride ever since. Their biggest, craziest adventure? Founding Dogfish Head Brewery and forever changing the landscape of American craft beer. From the moment Sam started home-brewing in his NYC apartment, he infused his beer with unusual ingredients like cherries, maple syrup, roasted chicory, and licorice. When he and Mariah officially launched Dogfish Head in 1995, it was the smallest brewery in America’s smallest state. 24 years (and countless pints) later, it was acquired by the Boston Beer Company for $300 million. Along the way, Sam and Mariah had one random experience after another: writing a bill to legalize their own brew-pub, winning best recipe at the Delaware Punkin Chunkin, and inviting Ricki Lake to their first tasting at Sam's apartment (spoiler alert: she showed up).See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Over nearly 50 years in the luggage business, Charlie Clifford has built two premium brands and weathered three existential crises: the recession of 1982, the travel slowdown post- 9/11, and the extreme aftershocks of Covid. His fist luggage company, Tumi, was inspired by his time as a Peace Corps volunteer in Peru. Charlie began by importing hand-crafted leather duffels from South America, but quickly pivoted into more durable and distinctive ballistic nylon bags. Business travelers loved them, and by the 1990’s, Tumi was spreading to Europe and Japan. Today, Tumi is owned by Samsonite and its stores are in airports and shopping malls around the world. Meanwhile, Charlie—unfazed by the challenges he’s faced over the years—has launched another premium luggage brand, Roam. See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
