One thing great about the bay area is that people are very open to meet you to give advice. I would contact all of the founders on this Mashable list of 44 female founders, and kindly ask to meet them for a cup of coffee and 10 minutes of their time.
You don't always need a conference or event to expand your network. The best way is to create a list of influencers and hustle your way into getting a few minutes of their time for advice.
Tip: Pay it forward. Offer them some help of your own and you'll have much more success reaching influencers.
