When she was just 19 years old, Melanie Perkins dreamt of transforming the graphic design and publishing industries. But she started small, launching a site to make yearbook design simpler and more collaborative. Her success with that first venture — and an unexpected meeting with a VC investor — eventually landed her the backing to pursue her original idea, and the chance to take on software industry titans like Adobe and Microsoft. Today, Melanie's online design platform Canva is valued at over $1 billion, joining the list of Australia's "unicorn" companies.

When Andy Dunn was in business school, his housemate Brian Spaly created a new type of men's pants: stylish, tailored trousers that fit well in both the hips and thighs. Together, they started the men's clothing company Bonobos, which became an instant hit due to the pants' signature flair and innovative e-commerce experience. But within a few years, Andy hit challenging roadblocks, including a struggle with depression and a falling-out with his co-founder and friend. Despite many moments of crisis, Andy steered Bonobos to massive success, and in 2017, it was acquired by Walmart for a reported $310 million.

Before Elizabeth Cutler and Julie Rice met, they shared a common belief: New York City gyms didn't have the kind of exercise classes they craved, and each of them wanted to change that.

A few months later, the first SoulCycle opened in upper Manhattan. Today, SoulCycle has cultivated a near-tribal devotion among its clients, with studios across the United States and Canada.

When Lisa sat down with Guy Raz in October, she described how her business expanded well beyond her Brooklyn kitchen.

Mark was looking for ideas to get rid of a massive pile of razors he had sitting in a California warehouse.

Just five years after launch, Unilever acquired Dollar Shave Club for a reported $1 billion. Recorded live in Los Angeles.
