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.
