I first met pg at SXSW several years ago, when he was swamped by hungry startup founders. The whole scene was intimidating to me--I hate crowds! I finally got to ask him a question, which I can't recall the exact content of now, but was something about women and YC. He suggested I email Jessica about it. I didn't do that--probably because I had been intimidated, and partly because I felt like he had punted on the question instead of giving me an actual answer (I now know that this was just part of his characteristic bluntness, and I definitely don't hold it against him especially given the environment in which the conversation happened, but at the time I didn't know pg and I found it offputting.)
Since then, I've had two good friends go through YC, both young white males. One of the companies is now "Internet famous" and shows up here on HN on a regular basis. The other one is still completely underground. Both of them enjoyed and recommended YC.
Another fellow entrepreneur here in Austin went through YC recently and we sat down and compared notes after he went through YC and I went through Techstars. Our conclusion: Techstars wins in terms of mentoring and support, but YC wins in terms of visibility and fundraising.
So, tl;dr I've met pg (briefly), I know one of the partners and a handful of YC founders, but they're not female. I didn't specifically seek out female founders who'd gone through YC, though now that you ask, I'm really curious to hear some of their viewpoints!
