About SidelineSwap
SidelineSwap - the leading online marketplace in sports - makes it easy for athletes, fans and sports families to safely buy and sell their gear online. We also work with leading retailers and brands in sports to power circular shopping experiences through our trade-in program and marketplace technology. Since launching the marketplace, millions of athletes have joined the community and contributed to our mission of making sports more affordable. On SidelineSwap you’ll not only find the largest collection of high-quality new and used sports gear on the internet, you will also connect with athletes who know about gear and love their sport. If you browse long enough, you might even find a few pros. We were founded in 2012 by former college athletes who realized how difficult it was to find high-quality used sports gear online. We’re entrepreneurs at heart, and we’re proud to empower a community of sellers who are entrepreneurs themselves. Sellers on SidelineSwap come in all shapes and sizes, from high school athletes selling last season’s gear, to college players unloading a career’s worth of equipment, to business owners who make a living on SidelineSwap, to leading brands like Callaway Golf. We’re backed by Global Founders Capital, FJ Labs, Riverpark Ventures, Teamworthy Ventures, and 500 Startups, and our advisors include current and former executives from Etsy, Reverb, Coinbase, Loews, Drizly, ESPN, and more. We’re alumni of 500 Startups, MassChallenge, and the Harvard Innovation Lab.
