Arena is a platform for sports fans to chat with one another during live events. Working with sports like UFC, Arena gives fans a place to connect that's not as cluttered as Twitter or Facebook, and that's focused just on the live event. Arena boasts some impressive audience numbers, claiming that it has more than 700,000 monthly active users and had over 100,000 uniques on a single UFC event. The startup is building widgets to allow websites and blogs to host Arena chats directly on their site. And Arena hopes to be at 10 million monthly active users in the next 12 months.
