It's no secret that venture capital and angel investing is 'clubby,' dominated mostly by middle-aged men.According to a 2007 study of angel investors in North America, 86 percent were male with an average age of 57. Women didn't fare any better in a similar UK study, where 93 percent of investors were male. A similar trend exists on the entrepreneur side: only eight percent of companies that receive venture capital funding are run by women. While the VC community seems stuck in an old boys network mentality, crowdfunding is radically re-shaping business investment and neutralizing gender bias, for both investors and entrepreneurs.
