Listia is a marketplace for buying and selling secondhand goods. The company was founded in 2009 and is headquartered in San Francisco, California. Listia allows users to trade items using a virtual currency called Listia credits, which can be earned by selling items or purchased with real money. The company has a strong focus on sustainability and encourages users to reuse and recycle items rather than buying new ones. Listia has received a number of awards for its innovative approach to online marketplaces, including the 2011 TechCrunch Disrupt Startup Battlefield.
