Male VCs who don’t have female professional peers are especially difficult to pitch on products that serve a female market. “Dozens of times, women have come and told me, I pitched to a firm and what do I hear over and over, ‘Oh, I will go home and ask my wife about it,’” says Trish Costello, an entrepreneur and founder of Portfolia, a venture capital investment platform designed for women. She is also CEO emeritus and co-founder of the Palo Alto–based Kauffman Fellows, a global training institute for venture capitalists.
