So you bought some crowdfunded stock and need cash. Assuming that you’re not contractually bound to hold the shares, can you liquidate?
There are now a few private markets where crowdfunded shares can be sold, including SecondMarket. SecondMarket claims to have processed over $1.4 Billion in trades in 2014. https://www.secondmarket.com/
You can also go to the Nasdaq Private Market. In addition, based on the high valuations and delayed IPO’s there are now some institutional funds that are buying into secondary sales. https://www.nasdaqprivatemarket.com/
