Environment: The Deal and Tech Confidential's 2006 Silicon Valley Summit.
Caveats: I based the count on the attendee list, rather than
counting heads. Many attendees 'popped in' for the panels they were
interested in, rather than spending the entire day at the conference.
Women at the 2006 Silicon Valley Summit: 10.22%
This seemed pretty typical of tech events, but given the venture industry focus I expected it to have a higher portion of women. The NVCA annual meeting, for example, had representation close to 17%.
