Depop is a circular fashion marketplace and peer-to-peer resale platform founded in 2011. It allows users to buy, sell, and discover affordable secondhand clothing, accessories, and vintage items through its app and web service. With 43.5 million registered users globally, Depop has popularized preloved fashion and generated over $2.5 billion in collective seller earnings, particularly appealing to Gen Z, with 90% of its active users under 26. Originally a social shopping app linked to the Italian fashion magazine *PIG*, Depop was created by Simon Beckerman. The platform combines social features with a marketplace model, targeting younger audiences. Under CEO Maria Raga, who joined in 2016, Depop has focused on community engagement through events and curated programs. Now the largest online fashion resale marketplace, it operates from offices in London, New York, and Manchester, and became a wholly-owned subsidiary of Etsy in 2021. Depop emphasizes style, value, and sustainability, making circular fashion accessible and inspiring for its users.
