As a previous member of the Ole' Boys Club with over 4 decades of experience, I suggest that an all-women's "organization-whatever" is sexist and does not necessarily advance what is needed for women to learn how to win in the startup 'system'. No one knows how many founders of startups fail but the estimate is >90 percent. What is most needed is special training on that which prevents failure and increases the probability of success. That information resides in those who have experienced success but more importantly failure. Ideally, a group finds the most articulate, insightful, and wise people who have failed and have a "gutter level, non-academic" town meeting. There is nothing academic about startups and games have little to no relevance to the real world. The challenge is to step out of the box and conduct events that are street-level important, not necessarily impressive - like training to be a special forces SEAL. I hope my comments are remotely responsive to your question.
