Calling all female investors: Even as women-run venture capital firms have sprung up over the past few years, there’s plenty of room for more, female VCs say. That was the message last week during a panel of women investors at Fortune’s Most Powerful Women Next Gen Summit in Laguna Niguel, Calif. “I think there’s room for 20, 40, 50 funds that are just for women,” said Nisha Dua, a general partner at BBG Ventures, a women-led firm that invests in startups with at least one female founder.
