I assume you have seen Ninjatickets.com which essentially does the same thing. Competition never hurts.
Well, we’ve been launched about a week and we’re already profitable. Also, we receive more traffic than about half of them and definitely have one of the better user interfaces.
Luckily this market is so massive that there’s room for many players (e.g. think of all the travel sites out there). Although we like to think we can be the best one. :)
If you're between buyers & sellers because buyers like you, you've got a business model.
