The challenge of getting more women in tech needs to involve the whole community - investors, entrepreneurs, engineers, both male and female. It cannot be a female only dialogue. I am a technical woman founder myself. And,my biggest challenge is fighting those subtle biases that men have. When I am in a meeting with investors, I find that I am treated in a patronizing fashion vs my male co-founders. Whenever the investor is speaking, he's addressing my male colleagues more and I am ignored. The only way to fight these is to make men aware of how they behave. Women already know it, since they are at the receiving end. Hence, I do not like closed, women only conferences.
