Listia is an online marketplace where people can trade items instead of buying and selling. Users get credits for giving away things they don't need and can then use those credits within the marketplace to get things they want. We founded Listia Inc. in the Spring of 2009 as a Y Combinator-funded startup in Silicon Valley. Listia.com launched on August 5, 2009 and we have since raised venture funding from some of the top investors, including Andreessen Horowitz, SV Angel and others.
