I’m here at Y Combinator headquarters in Mountain View, California, where over two dozen startups are showing off their wares to a room full of investors and press. The room is packed with with some of Silicon Valley’s most highly regarded VCs, angel investors, and entrepreneurs.

Demo Day has always drawn big crowds, but as the Y Combinator program has matured the quality of startups presenting has gotten noticably better (I remember being thoroughly impressed by many of the companies that launched in the last batch). Today’s companies look like they’ll be continuing that trend, even though many of them are only three months old.
