Listia (YC S09) raises $9M from General Catalyst for its used and free goods marketplace—mobile use up 2X in 3 months

Listia, the marketplace for used and free goods, has closed a $9 million Series A led by General Catalyst, with partner Neil Sequeira joining the startup’s board. As mobile growth takes off for the startup, the team will be using that financing to build out their iPhone and Android apps. It’s also looking to expand internationally, although that won’t happen until 2014 at the earliest.

The round brings the YC graduate to $11.17 million in funding, after it last raised a $1.75 venture round in 2011.

About one-third of buying and 20% of listing activity currently takes place on mobile, Listia co-founder and CEO Gee Chuang said. Although their iPhone app launched a solid two years ago with the Android version following in early 2012, mobile use is up 100% in the last three months.

“When we launched [the apps] they were these companion utilities,” Chuang said. “Our users, when they were away from the computer, used apps. In the last few months we’ve launched different updates to the apps to get them to be very standalone.”
