How I Built This with Guy Raz

In 1983, two hippie farmers decided to sell homemade organic yogurt to help raise money for their educational farm in New Hampshire. As the enterprise grew into a business, it faced one near-death experience after another, but it never quite died. In fact it grew — into one of the most popular yogurt brands in the US.

After high school, Marcia Kilgore moved to New York City with $300 in her pocket and no real plan. One step at a time, she became a successful serial entrepreneur. First, she used her high school bodybuilding experience to find work as a personal trainer. Then she taught herself to give facials, and eventually started her own spa and skincare line, Bliss. The spa became so popular that it was booked months in advance with a list of celebrity clientele. After selling her shares in Bliss, Marcia went on to start four new successful companies: Soap & Glory, FitFlop, Soaper Duper, and Beauty Pie.

In 2004, German programmer Tobias Lütke was living in Ottawa with his girlfriend. An avid snowboarder, he wanted to launch an online snowboard shop, but found the e-commerce software available at the time to be clunky and expensive. So he decided to write his own e-commerce software. After he launched his online snowboard business, called Snowdevil, other online merchants were so impressed with what he built that they started asking to license Tobi's software to run their own stores. Tobi and his co-founder realized that software had more potential than snowboards, so they launched the e-commerce platform Shopify in 2006. Since then, it has grown into a publicly-traded company with over 4,000 employees and $1 billion in revenue.

Angie and Dan Bastian weren't trying to disrupt an industry or build a massive company – they just wanted to put aside some money for their kids' college fund. In 2001, Dan stumbled across an internet ad touting kettle corn as a lucrative side-business, so he and Angie decided to take the plunge, investing $10,000 in equipment. At first, they popped kettle corn in front of local supermarkets in the Twin Cities and at Minnesota Vikings games. Eventually, they moved indoors to Trader Joe's, Target, and Costco – and got a crash course in how to run a business along the way. Angie's Kettle Corn eventually took on a bold new name: BOOMCHICKAPOP. And in 2017, the company was acquired for a reported $250 million. Recorded live in St. Paul, Minnesota.

In 1979, James Dyson had an idea for a new vacuum cleaner — one that didn't use bags. It took him five years to perfect the design, building more than 5,000 prototypes in his backyard shed. He then tried to convince the big vacuum brands to license his invention, but most wouldn't even take his calls. Eventually, he started his own company. Today, Dyson is one of the best-selling vacuum brands in the world, and James Dyson is a billionaire.
