Tyler Haney grew up playing several sports, but as an adult she gravitated toward activities such as walking her dog or hiking. Like many millennials who are more interested in fitness than competition, she couldn’t find an activewear brand that spoke to her. So she started Outdoor Voices, “a friendly, inclusive call to action that is nonprescriptive,” Haney explains. She created a range of high-performing yet soft fabrics—including her most recent, Tech Sweat—that are lightweight, fast drying, and worn by the likes of Gwyneth Paltrow and Frank Ocean. Sales have quadrupled, and in summer 2016 the company raised $13 million in funding, bringing total investment to $22.5 million. It’s been using that money to expand its retail footprint, opening three new stores in New York and Texas to go along with its original Austin location.
