Growing up, Danielle Walker’s family often convened for big meals prepared by her Italian grandmother, Grandma Marge. Back then, Danielle enjoyed a wide variety of food without restriction; but she began experiencing severe abdominal pain in her 20s that ultimately led her to totally transform her diet—cutting grains, lactose, sugar and more.  As Danielle found relief in this approach—and realized that others with similar ailments could as well—she began compiling her recipes in an online...

As one of the most successful creators on YouTube, Mark Rober doesn’t see what he does as a business. Instead, it’s a way to celebrate science in the most joyful way possible. While working as an engineer at NASA, he made his YouTube debut with a tutorial on how to make a gory Halloween costume with two iPads and a lot of duct tape. Over time, his videos became more elaborate, including a belly flop into a pool full of Jello, and a demo of a glitter-fart bomb to get revenge on porch pirates....

For decades, Shane Legg has anticipated the arrival of “artificial general intelligence” or AGI.  In other words: an artificial agent that can do all the kinds of cognitive tasks that people can typically do, and possibly more... Now as the Chief AGI Scientist and a co-founder of Google DeepMind, he stands by that prediction and is calling on the world to prepare.  This week on How I Built This Lab, Shane’s path to becoming an early AI expert and the work he and his team are doing to...

Best friends Rhett McLaughlin and Link Neal started out as “comedians for Christ,” and grew their partnership into one of the most successful YouTube platforms in existence. During college they created silly videos and songs for Christian events, and later built a following on YouTube before most people knew what it was. After struggling to find stardom in Hollywood, they continued to build a presence on YouTube: sampling punishingly hot peppers, writing ear-wormy songs about random things,...

Best-selling author and economics professor Renée Mauborgne thinks that too many entrepreneurs focus on the wrong things—consumed with making their companies outperform one another as they fight for a greater share of a crowded market space. But what if entrepreneurs focused on creating new markets instead of fighting over old ones? This week on How I Built This Lab, Renée shares insights from her Blue Ocean Strategy series to help founders crack open new opportunities. Plus, what is...

Whole30 began as a dietary experiment: For 30 days, Melissa Urban went without grains, dairy, legumes, alcohol and added sugar. She was trying to address several health problems, and the results were so extraordinary that she decided to share the diet with others.  What followed was a blog, a series of seminars, a best-selling book and eventually a wide-ranging wellness brand that’s helped millions of people identify the best diet for their own body. But in 2015, Melissa had to rethink...

The popular science fiction idea of beaming someone instantly to another location was part of David Nussbaum’s inspiration to design a “holoportation box.” His company, Proto, invented a device the size of a telephone booth that projects a hologram-type image so realistic it appears someone is standing inside... This week on How I Built This Lab, how Proto’s technology is used today to virtually transport professors, doctors, speakers, and celebrities to classrooms, hospitals, and events...

Isaac Larian moved from Iran to Los Angeles at age 17 with just a few hundred dollars, and went on to build one of the biggest toy companies in the world. Along the way, he took on Barbie with a wildly successful line of punky dolls called Bratz — a success that touched off an epic legal battle with Mattel. Today, at age 70, Isaac is still the CEO of MGA Entertainment, and says he still has the fighter’s instinct that he learned in the slums of Tehran. This episode was produced by Alex...

If you told 19-year-old Larry Liu that his hobby re-selling used electronics “for fun” would someday help him build a multi-billion-dollar company, he probably would have laughed. He was an electrical engineering student in Shanghai at the time. His goals were to land a corporate job and go to grad school in the U.S. He did both, starting with a job at Intel. But his passion for e-commerce stayed with him through his MBA and other corporate jobs. And when he moved to Northern California,...

Imran Chaudhri and his wife Bethany Bongiorno are responsible for bringing some of the most widely-used screened products to market—like the iPhone, iPad, and Apple Watch.  And while these devices have connected humans like never before, Imran and Bethany couldn’t help but wonder about the downsides of spending so much time tethered to screens. After leaving Apple, they eventually brought a new tool to life; something screenless... This week on How I Built This Lab, Imran and Bethany’s...

Mark Sisson made a big bet on mayonnaise, and won: four years after launching his Paleo-friendly condiment company Primal Kitchen, he sold it for $200 million. He succeeded partly because he drew lessons from his previous failures and accomplishments - as a marathon runner, Ironman triathlete and coach, frozen yogurt proprietor, sports supplement founder, TV show host, and Paleo book author. But Mark’s biggest business came at an age when most people contemplate retirement. He developed a...

Gene Berdichevsky and his team have been working for over a decade to solve a major problem: Lithium-ion batteries are not getting any better. They power our cell phones and laptops and nearly every other modern, rechargeable device—and at this point have reached their energy-storing limit. This week on How I Built This Lab, Gene discusses a new approach that could eventually make lithium-ion batteries 40% more efficient, unlocking a future where electric vehicles and other battery-powered...

In 2016, Fawn Weaver became fixated on a New York Times article telling the little-known story of Nearest Green, a formerly enslaved man who taught Jack Daniel—yes, that Jack Daniel—how to make Tennessee whiskey.  After diving deeper into the story, Fawn ended up purchasing the farm in Lynchburg, Tennessee where Nearest had taught Jack how to distill; and she began meeting the descendants of both men. She eventually decided the best way to preserve Nearest’s legacy was with a bottle of the...

What if you could no longer trust the things you see and hear? Because the signature on a check, the documents or videos presented in court, the footage you see on the news, the calls you receive from your family … They could all be perfectly forged by artificial intelligence. That’s just one of the risks posed by the rapid development of AI. And that’s why Tristan Harris of the Center for Humane Technology is sounding the alarm. This week on How I Built This Lab: the second of a...

When the iPhone 4 was released in 2010, Manish Chandra was dazzled by its picture quality, and saw an opportunity for a new type of mobile marketplace. A year later, he and three co-founders launched Poshmark, a shopping app for second-hand clothes and accessories, meant to capture the feel of going thrifting with your friends. The online community grew quickly and vocally—when Poshmark raised shipping fees, users lobbied furiously to lower them, and won. The company faced many more growing...

When Tristan Harris co-founded the Center for Humane Technology in 2018, he was trying to educate tech leaders and policymakers about the harms of social media.

This week on How I Built This Lab: the first of a two-episode series in which Tristan and Guy examine the serious risks posed by the rapid development and deployment of...

In 2002, John MacFarlane and his co-founders began tinkering on what was then an ambitious idea: create a new way to enjoy music throughout the home, without wires. At the time, streaming and the iPod were brand new, and smart speakers were over a decade away. But the team at Sonos engineered a top-quality wireless sound system, and–with many fits and starts–integrated it with mobile technology and, eventually, Siri and Alexa. Along the way, John and his team contended with the early...

There’s a new car coming to market that will probably make its owners search out the sunniest spots in the parking lot… Aptera Motors is designing and manufacturing this car: a plug-in electric hybrid that can run up to 40 miles on a single, solar-powered charge. This week on How I Built This Lab, Steve Fambro shares how he and his co-CEO revived their once-defunct auto company thanks to the promise of solar energy. Plus, Steve’s take on why today’s vehicles require so much energy, and how...

Gabi Lewis and Greg Sewitz founded Magic Spoon to create a sugary breakfast cereal without the sugar. If that sounds daunting, consider their first business: protein bars made with cricket flour. Riffing on an idea that began as a college assignment, the founders ordered live crickets to roast at home, and worked with a top-rated chef to perfect their recipes. The only problem: getting people to eat a snack made of ground-up bugs. When Exo protein bars eventually stalled, the pair pivoted to...

In 2012, Ariel Kaye saw a tantalizing opportunity, but wasn’t sure she was the one to seize it. She’d never started a brand and didn’t think of herself as an entrepreneur, until she noticed how frustrating it was to buy bed linens in a big box store. Taking inspiration from Warby Parker and Everlane, Ariel quit her day job to launch a brand of DTC luxury sheets, made in Europe but exuding a California vibe, with photos of models lounging in semi-rumpled beds. As a solo founder, Ariel had to...
