Never underestimate the business value of being able to make a good sandwich, appreciate a good meal, and to make people comfortable.
As the comment I replied to remarked about the tech ability of the founders I'd have to say that I'm willing to bet that the young Australian woman that started a trading site with her younger brother very probably has a good grip on the mechanics of web site building and operation. Further she appears to have had the good sense to outsource for the tech when scaling up for the American market.
I've been involved in a number of businesses that have gone from small to international, nearly half with women founders and nearly half with tech founders (with some overlap). In almost all cases the telling important factors weren't gender or tech ability but that elusive EQ ... the ability of the founders to rally a team and have them hold the faith while deals were formed and products deployed.
