You're Building WHAT? Shocking Your Way To Startup Success

Lulu, Rap Genius, and Bang With Friends are shocking, controversial -- and their founders are all speaking at Business Insider's Startup Conference in October.

Together the three companies have raised more than $24 million.

Lulu is an app that lets women rate the men they know and give them scores. It has raised $6.35 million and boasts 1 million users so far.

Rap Genius is a web site where people explain rap lyrics. A year ago they claimed they would have the world's largest web site. They have raised $16.8 million and according to Quantcast, has 13 million unique users per month.

Bang With Friends is an anonymous way for you to hook up with your Facebook friends, which some 200,000 people have already done. It has raised $1 million in funding and hosting 1.1 million active users.

These companies are pushing boundaries and redefining acceptable business models. Come hear what they have to say about shocking the public at Startup 2013.
