Y Combinator Launches 39 Startups At Demo Day 2012 – Vote For Your Favorite

Y Combinator Spring Demo Day 2012

Based in Silicon Valley, Y Combinator is one of the hottest startup accelerators offering seed funding for startups. Founded by Paul Graham just 7 years ago, YC has produced such companies as Airbnb, Reddit,, and more. This spring they put out another large and stellar class of startups. We covered the 31 Y Combinator startups in the summer class last August.

This year, the spring class of companies runs the gamut, with a strong emphasis on mobile technology. A total of 39 startups participated in demo day and we’ve aggregated a list of them below. All the companies will receive a check from Ron Conway and Yuri Milner for $150,000, while some also secured a Series A round. That said, we want to hear what you think of this class of startups. Check out the list below (in alphabetical order) and vote for your favorite Y Combinator startup from spring 2012 demo day.

    The Loan Mods should be done by a real estate broker period. It is quite simple in California the upfront money goes into a trust. After services are rendered then they get paid. 25% for consultation, 75% when loan mod is complete. I believe it should be 25% initial consultation, 25 loan preparation 50% when loan is complete. I am sorry people an attorney doing a loan mod is an attorney who can’t find any other work. We are the people who talk to the banks. We are the people who are going to get them a short-sale if the loan mod gets rejected. If you want a loan mod use a reliable broker. P.S Reginaldo if you can’t afford your neg am you can’t afford a loan mod, if an attorney says you can well you just lost your retainer fee. Benny
