About SidelineSwap

SidelineSwap operates as a specialized online marketplace catering to the sporting goods sector, facilitating consumer-to-consumer and business-to-consumer transactions of new and used sports equipment. The company was founded in 2012 by Brendan Candon and Anthony Piazza, former college athletes who identified a gap in the market for a dedicated platform for trading sports gear. Candon's background in finance and his experience as a lacrosse player, coupled with Piazza's expertise in software development, provided a solid foundation for the venture. They initially conceived the idea after realizing the amount of unused gear they and their teammates had accumulated.

The platform's business model is centered on a marketplace structure, connecting athletes, parents, and small sporting goods businesses. Revenue is generated through a commission-based system, where SidelineSwap takes a percentage of the final sale price from the seller. The fee is 12% for sellers on their first 0-5 sales, which decreases to 9% after the sixth sale, incentivizing active participation and volume selling on the platform. This model has proven effective, with the community growing to over 1.5 million athletes who have listed more than $1 billion worth of equipment since the marketplace officially launched in 2015.

SidelineSwap's value proposition lies in offering a wide selection of sporting goods at competitive prices, creating a circular economy that keeps equipment in use and out of landfills. The platform serves a dual purpose: it allows sellers to monetize underutilized assets and provides buyers with affordable access to quality gear. Key features include integrated shipping and payment processing, seller protection policies, and a community-driven content section that helps buyers make informed purchasing decisions. Based in Charlestown, Massachusetts, the company has successfully carved out a niche in the resale market by focusing exclusively on the sports community, fostering a user base with shared interests and expertise.
