LaunchRock incentivizes people who sign up for your product launch to share it with their friends.

Now, we're building a product that goes BEYOND launch – a platform for better engaging existing users/customers and acquiring new ones through social.

During our private beta LaunchRock has generated 1,000,000+ signups for 3,000+ customers. We're about to come out of beta and open the product to the 50,000+ customers on the waiting list.
