The Kurbo Founding Story

It all started when co-founder and CEO Joanna Strober was struggling to find an effective program for managing her son’s weight. While hundreds of weight loss tools were available for adults, none of them were safe for kids. Joanna’s search led her to Stanford’s Pediatric Weight Control Program, which has been proven effective and safe at helping kids lose weight and keep it off. Unfortunately, the program cost thousands of dollars, operating on an inconvenient schedule for working parents, and was only available locally. Joanna knew that if she could translate Stanford’s proven program into a convenient and affordable format, she would have the potential to help millions of kids and families worldwide. That’s how Kurbo was born.
