The fact that 10% of founders presenting at this week’s YC Demo Day are women might not sound like a victory, but it’s actually more than double the percentage in previous classes.

This week 47 startups presented at Y Combinator Demo Day. How many of the founders up there in front of investors were women? Nope, not half, not even close. Try one in ten. We have a way to go, but 10% female is still an improvement given that previous classes managed only a measly 4%.

Y Combinator partner Jessica Livingston told TechCrunch the increase wasn’t down to any particular effort on the part of the accelerator, but simply reflects the fact that more talented women are applying. She also noted that more of the female founders in this class served as team leaders than in any previous class.

So who are these women and what are they pitching? YC alum and Referly founder Daniella Morrill made our job easier by rounding up the nine women at the publically launched companies in an in-depth post. Here they are:

If you’re in the market for more analysis of the class (shrunken by a third to the relief of both investors and accepted startups, TechCrunch reports) and the types of companies being pitched (crowdfunding seemed hot), there’s tons of coverage online, including picks of companies to watch.
