How I Built This with Guy Raz

In the summer of 2000, Razor scooters were everywhere—on sidewalks, in schools, even in Silicon Valley offices. At the center of it all was Carlton Calvin, an ex-lawyer turned toy mogul who had already ridden—and crashed—multiple crazes, from Pogs to yo-yos.

Carlton knew how to spot what kids wanted before the world caught on. But when Razor went from selling a million scooters a month to zero almost overnight, his business teetered on collapse.

This is a story about timing, obsession and instinct: knowing kids would snap up Slammers with scorpions inside, seeing the potential of a sleek new scooter from Taiwan, and learning how to turn a craze into a lasting global brand.

In this episode, you’ll learn:

 • Why most “overnight successes” collapse as quickly as they rise
 • The power of partnerships– and trust– in scaling quickly
 • How to think like your customer (in Carlton’s case, a 10-year-old boy)

This episode was produced by Kerry Thompson with music by Ramtin Arablouei. It was edited by Neva Grant. Our audio engineers were Patrick Murray and Maggie Luthar.

Advice Line: Playing to Your Strengths

What does it take to turn a Brooklyn beer salesman into the king of iced tea?

In the early 1990s, the iced tea market was dominated by Lipton, Nestea, and Snapple. But Don Vultaggio saw an opening. A single moment—watching Snapple cases fly off a truck in winter—sparked an idea that would change his life: why not sell tea in a tallboy can? 

AriZona exploded—outselling Snapple and becoming a multi-billion-dollar brand. 

Behind the success was struggle: Don fought to keep the company private. and faced a painful 10-year legal battle with his former friend and co-founder. 

In this episode, Don reveals:

 • How he stayed independent in an industry dominated by giants. 
 • Why Snapple stumbled after being acquired—and how AriZona avoided the same fate.
 • Why he wants AriZona to remain a multi-generational family business.
 • Why packaging can be more powerful than advertising.
 • How AriZona holds onto its 99c price tag

In 2001, three web designers built a quirky email tool called Mailchimp.

It wasn’t their main business.

Then…one surprising spreadsheet changed everything.

In this episode, Ben reveals:

 • The decision that tripled their revenue 
overnight • How a mispronunciation on the world's biggest podcast turned into a marketing masterstroke
 • How a painful wake-up call about leadership reshaped the company’s culture

Listen now to hear how guerrilla billboards, a monkey logo, and a string of improbable breaks built one of the most recognizable names in tech.

Advice Line with Jamie Siminoff of Ring (August 2024)

Amy Errett had a successful career in finance and venture capital before taking a leap into an entirely new business: hair color. When her wife complained about the indignities of coloring her hair at home, Amy realized the sector was ripe for a makeover. At age 56, she dove into the minutiae of dyes and developers, launching her own formula in 2013, and naming it after her daughter. Madison Reed’s early successes were marred by a management meltdown, when Amy had to break with three of her co-founders—an experience she describes as one of the most difficult of her life. Today Madison Reed is available in thousands of stores across the US, and runs nearly 100 of its own salons.

This episode was produced by Sam Paulson with music composed by Ramtin Arablouei. It was edited by Neva Grant with research by Iman Maani. Our engineers were Patrick Murray and Kwesi Lee.
