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 pains before being acquired by the Naver Corporation for $1.2 billion in 2023. It now has over 100 million registered users around the world.This episode was produced by Sam Paulson with music composed by Ramtin Arablouei.It was edited by Neva Grant with research help from Katherine Sypher.Our engineers were Robert Rodriguez and Josh Newell.You can follow HIBT on Twitter & Instagram, and email us at hibt@id.wondery.com.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

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 unreliability of WiFi, and faced stiff competition from much bigger companies. But today, Sonos is an established player in music, with projected sales of over $1.5 billion this year. This episode was produced by Katherine Sypher with music composed by Ramtin Arablouei.It was edited by Neva Grant with research help from Sam Paulson.You can follow HIBT on Twitter & Instagram, and email us at hibt@id.wondery.com.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

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 another ambitious idea: breakfast cereal that tasted like the Fruit Loops and Cocoa Puffs of childhood–but minus the sugar and grains. Drawing on their roller-coaster experience with Exo, Gabi and Greg revisited winning strategies, and scrapped the plays that didn’t work, eventually building Magic Spoon into a nationwide brand.This episode was produced by J.C.

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 figure out everything herself, from manufacturing to supply chains to how to get through to investors. Today, Parachute Home offers a wide range of home goods and has expanded beyond its website to 26 physical stores across the U.S. This episode was produced by Chris Maccini with music by Ramtin Arablouei.Edited by Neva Grant, with research from Katherine Sypher.Our engineer was Josephine Nyounai.You can follow HIBT on Twitter & Instagram, and email us at hibt@id.wondery.com.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Tiffany Masterson was a stay-at-home mom in her 40s when she launched her skin care brand, Drunk Elephant, in 2013. Six years later, she sold it for $845 million to the Japanese beauty giant Shiseido. Just six years! And she did it all with little to no experience in skin care, retail, or business. The professional branding and skin care world thought she was making huge mistakes: They panned her brand's name, product design, and strategy of focusing on only one high-end retailer. But Tiffany proved them wrong with great strategic instincts, incredible determination, and an unwavering belief in her products - and herself.This episode was produced by Alex Cheng with music by Ramtin Arablouei.Edited by Andrea Bruce, with research from Katherine Sypher.Our audio engineer was Josephine Nyounai.You can follow HIBT on Twitter & Instagram, and email us at hibt@id.wondery.com.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
