LadyBoss

Physical fitness has long been central to Kaelin Tuell Poulin's life. When she was 19 and clinically obese, she lost 65 pounds in under a year. Just a few years later, that journey would serve as the centerpiece for her career, too. In 2015, she and her husband Brandon Poulin founded LadyBoss, the Albuquerque, New Mexico-based weight-loss business, which today sells resources and tools to women looking to shed pounds. For $27 a month, LadyBoss customers gain access to an app with meal plans, recipes, workout guides, and more. There's also personal training and coaching, a supplements line, and gear--all sporting a neon pink LadyBoss logo. The company is on track to book between $40 and $50 million in revenue this year. --Anna Meyer
