Letgo

Was one of the two largest mobile C2C secondhand goods marketplaces in the US before merging with OfferUp in 2020

Letgo was a mobile-first classifieds platform that allowed users to buy and sell used items locally through a simple, photo-driven listing experience. Founded in 2015 and headquartered in New York City, letgo rapidly gained traction by making it extremely easy to post items for sale — users could snap a photo and have a listing live within seconds, with AI-powered tools automatically generating titles and categories. The app grew to become one of the most downloaded shopping apps in the United States, amassing over 100 million downloads and tens of millions of listings across a wide range of categories including electronics, furniture, vehicles, and apparel. Letgo distinguished itself from competitors like Craigslist through its polished mobile interface, in-app messaging, and user profile features that added a layer of trust and social context to peer-to-peer transactions. Backed by significant venture capital — including major investments from Naspers — letgo invested heavily in marketing and product development to compete aggressively with rivals such as OfferUp and Facebook Marketplace. The platform monetized primarily through promoted listings and advertising products that allowed sellers to boost the visibility of their items to local buyers. In 2020, letgo merged with OfferUp, its primary competitor, in a deal that consolidated the two largest mobile C2C marketplaces in the United States. Following the merger, the letgo brand was retired and its users and listings were migrated to the OfferUp platform. The combined entity, operating under the OfferUp name, became the dominant player in the US mobile secondhand goods market, carrying forward many of letgo's product innovations and its large user base.
