SecondMarket, a secondary trading market for pre-IPO companies, announced today that it has partnered with CircleUp, an equity-based crowdfunding platform.

PandoDaily reported today that New York-based SecondMarket will cross-list companies raising funding on the CircleUp platform. This gives SecondMarket users the ability to invest in the equity of early-stage companies. So far, five companies have completed funding rounds on the CircleUp platform.

This news comes three weeks after SecondMarket’s announcement of a similar partnership with AngelList.

SecondMarket demonstrated at FinovateStartup 2009.
