Haymaker, created for an entrepreneur, enabled users to create sports dates with friends-of-friends, via Facebook. We created an iPhone app that accessed your social graph, connected with application users, and drew a photo wall of all of your friends, and friends-of-friends, that have used the app and expressed interest in 9 sports. You can then follow up with them via email. Custom messaging prompts you to message the user with “bragging rights,” who won or loss. The goal was to incentivize exercise and social outings with your Facebook social graph.
