Campsider is the premium marketplace for sports equipment, new and used, bought and sold by people who actually know their gear. Where generalist platforms treat sports equipment as a commodity, Campsider treats it as a category worth building for: 3,000 brands, 200 sport categories, a 12-month warranty, free returns, and a community that knows the difference between good and great kit. Founded in 2020 and live across France, Belgium, Germany, Italy, Spain, and Switzerland, Campsider has validated its model in winter sports and is actively expanding into outdoor. The company counts 60 B2B clients and operates a hybrid B2C and B2B2C model, co-founded by Arthur Rocle (HEC/École 42) and Thomas Gounot (EM Lyon).
