How I Built This with Guy Raz Wondery

While working as a psychologist in the Bay Area helping people with their problems, Mary Waldner discovered one of her own; at the age of 43, she was diagnosed with celiac disease. The foods she’d been eating all her life had been making her sick, so Mary came up with a solution. She decided to create a healthy gluten-free snack cracker that she could make at home, and eat in restaurants when her friends were eating bread. As it turns out, lots of people loved Mary’s crackers and they encouraged her to start her own company, which Mary turned into a multi-million dollar business.

Matanya Horowitz is not above dumpster diving in the name of innovation. His company, AMP Robotics, has developed robots to help waste management facilities better sort through incoming trash and separate recyclables. AMP has tested and refined their technology since launching in 2014, in part with materials that Matanya and his team personally picked from the garbage. Today, their robots can be found in hundreds of facilities worldwide, including some of their own.

This week on How I Built This Lab, Matanya talks about the business of recycling and his company’s work to increase global recycling rates. Plus, Matanya explains how investors have come to see the value in garbage and dives into the reasons why so much recyclable material ends up in landfills.

While working long hours as a Wall Street analyst, Melissa Butler started making lipstick in her kitchen as a hobby. But it soon turned into an obsession, costing thousands of dollars. She was frustrated by the lack of diversity in the cosmetics industry, and as a Black woman, wanted to create lipstick colors that complimented her complexion and style. So in 2010, she launched The Lip Bar, with bold colors like green and purple, and boozy names like "Cosmo" and "Sour Apple Martini." Undeterred by a disastrous appearance on Shark Tank with her partner Rosco Spears, Melissa was motivated to pitch her lipstick to Target, and in 2016, launched a new color on Target's online store. Today, The Lip Bar—rebranded in 2021 as TLB—has expanded to stores nationwide and is now the largest Black-owned makeup brand sold in Target stores.

When Aryé Elfenbein and Justin Kolbeck met in 2011, they had no intention of starting a business. Aryé was a cardiologist, and Justin was a diplomat who had lived in countries all over the world. But their chance meeting at a dinner party led to a deep friendship focused on working together to change the world. Through regular Saturday morning brainstorming sessions, they settled on pursuing a scientific approach to growing meat for human consumption.

This week on How I Built This Lab, Aryé and Justin discuss the problems with modern seafood production and how their company, Wildtype, hopes to revolutionize the industry by using stem cells to cultivate real, sushi-grade salmon... without harming any actual fish.

From a coffee cart parked uneasily in a grocery parking lot, Travis and Dane Boersma grew Dutch Bros into a sprawling chain of 700-plus beverage restaurants. Before they got started in Grants Pass, Oregon, in 1992, Dane had never tried espresso, and neither brother knew how to make it. But with the help of nearby experts, they learned the craft—and even improvised their own recipes, like mocha made with chocolate milk from a local dairy. Eventually, Dutch Bros would go from pushcarts to drive-throughs, and from small-town Oregon to Wall Street—with a nearly $500-million IPO in 2021. Along the way, the brothers’ special connection carried them through good times and bad, until an unexpected family tragedy shook the business to its core.

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 often overlooked by innovative startups. 

This week on How I Built This Lab, Donnel talks with Guy about BlocPower’s work to modernize buildings nationwide and transition them to clean energy sources. BlocPower has raised more than $100 million from Wall Street and Silicon Valley investors, and has partnered with cities across the country to create greener, safer spaces for their residents.
