Go to any Startup Weekend, and you’ll likely find the same thing. The majority of the geeks designing and developing new business ideas are … dudes. In fact, of the 630 Startup Events around the world, an average of 82 percent of the participants have been men.

But that won’t be the case at an upcoming Startup Weekend in Seattle. A group of Seattle area geeks – including Madrona Venture Group’s Julie Sandler and Decide.com’s Shauna Causey — are organizing Startup Weekend Women’s Edition that caters to entrepreneurial women. The date is slated for July 13th to 15th, and the event will be held at Madrona Venture Group in Seattle.

“We want to encourage more women in our area to explore their own entrepreneurial ambitions and continue to take leadership roles in the startup community,” said Sandler, a former Amazon.com employee who joined Madrona last year.  “We also hope this event will serve as a catalyst for women participants to start their own companies.”

The event is limited to about 90 participants. And, in case you were wondering, guys are allowed only if they are invited by a woman attendee. Just 10 to 15 slots are open for men.

This marks the second time that Startup Weekend, a Seattle-based non-profit that hosts 54-hour coding marathons around the world, is hosting a woman-oriented event. (The first was in San Francisco).

Scheduled mentors for the weekend event include: Jenny Lam, co-founder of Jackson Fish Market; Kim Rachmeler, Executive Chair of Vittana; Felix Anthony, former VP of Kindle Software and Digital Platform at Amazon; and Kate Matsudaira, VP of Engineering at Decide.com.
