SidelineSwap Company Overview

SidelineSwap connects athletes so they can buy, sell, and learn about new and used sports gear. We were founded in 2012 by former college athletes who realized how difficult it was to find high-quality used sports gear online. Since launching the marketplace, hundreds of thousands of athletes have joined our 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’re entrepreneurs at heart, and we’re proud to empower our community of sellers. Sellers on SidelineSwap come in all shapes and sizes, from high school athletes selling last season’s gear, to former college players unloading a career’s worth of equipment, to business owners like Eric (see below) who make a living on SidelineSwap.

We’re backed by Global Founders Capital, Riverpark Ventures, Fullstack Sports Ventures, Teamworthy Ventures, FJ Labs, and 500 Startups, and our advisors include former executives from Amazon, Etsy, Seamless, Staples, and ESPN. We’re alumni of 500 Startups, MassChallenge, and the Harvard Innovation Lab.
