HIBT Lab! Universal Standard: Polina Veksler

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...


Noom: Saeju Jeong

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...

HIBT Lab! Quaise Energy: Carlos Araque

Growing up in Colombia, Carlos Araque and his father liked to take apart bicycles and motorcycles then put them back together. This love of tinkering led Carlos to study engineering at MIT and eventually launch a career in the oil and gas industry. After 15 years of this work, Carlos realized he was uniquely suited to be a part of the global energy transition away from fossil fuels. He returned to his alma mater to help run a startup accelerator, and soon, Quaise Energy was born. This week...

Dogfish Head Craft Brewery: Sam and Mariah Calagione

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...


HIBT Lab! IDEO: David Kelley

It wasn’t unusual for David Kelley to take calls from Steve Jobs in the middle of the night. 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. David also led the founding of Stanford’s, where students learn to use design principles to solve complex problems. This week on How I Built...


Tumi & Roam Luggage: Charlie Clifford

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...


ICYMI... HIBT Lab! Colin and Samir: Colin Rosenblum and Samir Chaudry

This week on How I Built This Lab, we're throwing it back to our very first Lab episode. 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.) The creator economy barely existed a decade ago, but has quickly become a multi-billion dollar industry with a massive global reach. Colin and Samir discuss their 10-year business journey, and share insights...


Twitch: Emmett Shear

In 2011, when Emmett Shear pivoted the live streaming service into the video game platform Twitch, people warned him that gaming was just a niche. But unlike his first two ventures, video games were something Emmett instinctively understood: he and his co-founder Justin Kan had been playing them together since they were kids. Emmett built a user base on Twitch by asking streamers exactly what they wanted and giving it to them: revenue opportunities, streamer fan clubs, customizable...


HIBT Lab! The Financial Diet: Chelsea Fagan

Chelsea Fagan got her first credit card when she was a senior in high school. She quickly maxed it out, racking up debt that would burden her through her early twenties. Then, in 2014, Chelsea started a blog as a way to keep track of her spending habits and get her financial life back on track. She called it “The Financial Diet.” This week on How I Built This Lab, Guy talks with Chelsea about how she turned that blog into the multimedia personal finance business it is today. Plus, Chelsea...


TaskRabbit: Leah Solivan

One snowy night in Boston, Leah Solivan ran out of dog food for her 100-pound yellow lab. She wondered: shouldn’t I be able to resupply Kobe without going to the store? That was the origin of TaskRabbit, an online errand service that matches users with “taskers” to do deliveries and other chores. When Leah left her IBM job to start coding the service, the peer-to-peer economy was still in its infancy. But she saw that three important developments—mobile, location services, and social...


HIBT Lab! BlocPower: Donnel Baird

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 founded BlocPower in 2014 to address this precise problem, focusing on low-income communities so...


Happy Family Organics: Shazi Visram (2020)

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. That gave Shazi her initial idea: why not make organic pureed baby food, and sell it frozen instead of jarred? People told her she was crazy to take on Gerber, but she convinced dozens of friends and family to invest in Happy Baby. Nearly 20 years later, the brand is known as Happy Family...


HIBT Lab! Climeworks: Jan Wurzbacher

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. But that’s not all. 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 Jan Wurzbacher, co-founder and CEO of Climeworks. They discuss how Jan and his team built the world’s...


The Tonight Show & Electric Hot Dog: Jimmy Fallon

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 with perfecting his impressions of Richard Pryor and Steve Martin, with the goal of one day starring on...


HIBT Lab! The Sorry Girls: Kelsey MacDermaid and Becky Wright

YouTubers Kelsey MacDermaid and Becky Wright – better known as The Sorry Girls – have always had an affinity for production. When they met as film students back in 2010, little did they know that the DIY videos they were creating for fun would eventually lead to full-fledged careers co-founding and leading their own media company. But building to where they are now, with over 2 million subscribers and counting, didn’t exactly come with a blueprint… This week on How I Built This Lab, Kelsey...


Affirm: Max Levchin (Part 2 of 2)

After PayPal sold to eBay in 2002, Max Levchin could have relaxed on a beach for the rest of his life. But that’s not the kind of person he is. He isn’t happy unless he’s coming up with new ideas and building companies – so much so that he actually fell into a dark place after leaving PayPal. He didn’t fully find himself until years later, when he rediscovered his passion for the “hard, valuable, fun” problems of fintech. Now, Max runs another billion-dollar company: Affirm, a “buy now, pay...


HIBT Lab! Mark Cuban Cost Plus Drug Company: Mark Cuban

Serial entrepreneur Mark Cuban was one of the very first guests on How I Built This, way back in 2016. Mark has been founding and investing in startups for decades, but he’s never put his name on a company until now. This week on How I Built This Lab, Mark joins Guy to talk about what he’s been up to since he was last on the show. They discuss his interest in NFTs and how his latest business, the Mark Cuban Cost Plus Drug Company, is looking to disrupt the pharmaceutical industry. Listen...


PayPal: Max Levchin (Part 1 of 2)

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...


HIBT Lab! Google: Sundar Pichai

Drive. Docs. Chrome. Maps. Gmail. Android. What do these products have in common? Of course, they’re all Google, but what you may not know is that they all came to fruition under the management of the same person: Sundar Pichai. This track record in product development ultimately landed Sundar the CEO role at one of the biggest, most innovative companies in the world. This week on How I Built This Lab, Sundar reflects on the unique journey that led him to Google, and the values that inspire...


Pitchfork: Ryan Schreiber

While working at his local record store at age 20, Ryan Schreiber dreamt that his scrappy music review webpage might one day grow into an influential music publication. Working out of his parents’ house, he wrote about indie music because he loved it, and recruited like-minded friends to do the same. In 2000, a rhapsodic review of Radiohead’s “Kid A” got huge attention online, and soon Ryan’s site began to attract tens of thousands of users—building a reputation for pointed reviews that...
