The round was led by Global Founders Capital, with participation from NBA legend David Robinson's Admiral Capital, Peak6 Sports, RiverPark Ventures, FJ Labs and The Player's Impact -- a syndicate of professional athletes and Olympians. This round brings the company's total funding to $8.9 million -- $7.1 million raised in under a year.

"Our goal has always been to build the best shopping experience for the sporting goods customer," said Brendan Candon, co-founder and CEO of SidelineSwap. "To us, that means creating an experience that combines commerce, community and content. With this round of financing, we'll focus on building the largest selection of used and new inventory at the best prices, and continue our efforts to help make high-cost sports more accessible to athletes everywhere."

The sporting goods industry is the latest retail sector that's ripe for disruption. With bankruptcies from big players, including Sports Authority, City Sports and Golfsmith, the $120 billion industry is pointing toward SidelineSwap's online marketplace and value proposition. SidelineSwap tops competitors in the space like eBay and Amazon with more used inventory available for sale in their top sports. Similar to fast-growing marketplaces in other categories, like Poshmark, Reverb and Etsy, SidelineSwap is poised for success with its early traction and this latest round of financing.

Since launching in 2015, the company has quickly gained traction with young athletes, who value the friction-free, mobile-first, selling experience and the average discounts of 40% on quality used and new gear. The vast majority of users on SidelineSwap are selling online for the first time which means they're providing access to inventory and prices you can't find anywhere else. More than 200,000 athletes have joined SidelineSwap to date, driving three straight years of triple-digit growth.

"We are excited to expand our portfolio of sports technology investments and tap into our sports network to help accelerate SidelineSwap's growth," said David Robinson, Admiral Capital co-founder. "This rapidly growing platform has social benefits consistent with the Admiral Capital Group mission and we look forward to helping make sports more affordable and accessible."

Sellers on SidelineSwap are already having tremendous success, with some sellers earning upwards of $250,000. Eric Fanelli, a hockey dad from Connecticut, turned selling on SidelineSwap into a full-time job by partnering with local college, club and professional hockey teams, including the Detroit Red Wings minor league team, to source and sell "pro-stock" inventory designed especially for pro and college athletes.

"SidelineSwap is delivering a superior consumer experience to athletes and represents a powerful new channel for sellers of all kinds," says Reid Snyder, Managing Director at Peak6 Sports, a sports and technology venture capital firm that has participated in all three rounds of SidelineSwap funding. "By bringing a scalable and much needed solution to the sporting goods and apparel vertical, they've unlocked a significant growth opportunity."

This Series A funding is SidelineSwap's third round of financing. The company previously raised a $2.1 million seed extension in fall 2017, and a $1.8 million seed round in spring 2016.
