15 years ago, Kara and her husband, Theo, set on on a grand adventure. With no experience in the beverage industry, they wanted to create a beverage drink with only one thing in it, fruit...nothing else. That proved harder than you might think. She chronicles the ups and downs of Hint Water in her new book, Undaunted.

Kara and I had an in depth conversation about the business, the book, her family, and her biggest challenge moving from Founder to CEO.
