Former U.S. Marine Corps. sergeant Alex Stone wants to help young veterans catch the eyes of college athletic recruiters. And he’s left his job at Under Armour to make it happen.

Stone spent five years at Under Armour as a development and product line manager before leaving last month to focus on his startup Athletes of Valor, which aims to connect recent military veterans who played a varsity sport in high school with college coaches and recruiters. The web site is in beta and launches in full around Veterans Day in November.

Stone, who played hockey and football at Swampscott High School in Swampscott, Ma., enlisted in the Marines after graduation. Once he finished his four years of service, “I struggled to find purpose and also struggled to find employment,” he says. “One of the only regrets that I have in life is that I never went back and played sports and earned my degree. I want to make sure that everyone similar to me has that opportunity to go back and play, and they understand how to do it.”

Most young veterans have no idea that they still have their NCAA eligibility, Stone says—and he expects educating them on this fact will be Athletes of Valor’s biggest challenge.

But the bigger challenge could be convincing college coaches to take a chance on athletes that haven’t played their sport in years. “The coaches I’ve talked to,” Stone says, “they want these players. They have stories about having a veteran in their locker room before, and how great an experience it was, not only from an athletic standpoint, but from a leadership standpoint. And they say the biggest challenge is that they don’t know how to find them. Athletes, and service men and women, they don’t fully understand how to market themselves to coaches when they’re 22 to 26 years old. So what we’re doing is connecting those dots.”

Marketing the platform will help, and sparking the interest of coaches ahead of time will help. For those efforts, Stone has the support and financial backing of Jordan Fliegel, an entrepreneur who has invested an undisclosed amount in Athletes of Valor, along with Boston VC firm Accomplice. Fliegel is Athletes of Valor’s chairman, while Stone is CEO.

Fliegel has some key experience in creating a marketplace-style listing platform. In 2011 he founded the company CoachUp, a platform that sets up private coaches with a listing page so young athletes (or more often, the parents of young athletes) can find them and book lessons. The company raised $10 million in funding, grew quickly, and managed to get Golden State Warriors star Stephen Curry on board as a brand ambassador and equity stakeholder. Think of CoachUp as a Yelp for private coaches—and Athletes of Valor is basically looking to do the same for young military-veteran athletes.
