Startups And Top Investors Unite At Y Combinator's Tenth Demo Day

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.

Some of the companies presenting today have already launched; we’ll provide a brief recap of what they’re up to, and then link to our past coverage.

The company says that it differentiates itself from other developers by releasing quick, smart games at a very rapid pace (they can develop a game in about a week. The company has built its own analytics platform for social games called Rankador, which they liken to a ‘PageRank for social games’.

Etacts – Etacts, which launched in February, is a service to help ensure that you keep in touch with the friends and colleagues you care about. It can help prioritize messages, alert you if you’re falling out of touch with someone, and more. It was also the first service to implement oAuth for Gmail.
