The only thing that sucks more than paying a small fortune to a broker for sold-out tickets is getting there to find out scalpers are dumping tix below face, and Scary Spice has laryngitis. Taking the guesswork out of after-market ticket purchasing, SeatGeek.
Just launched by a duo who set up shop through University City's DreamIt Ventures, totally free Farecast-esque SeatGeek scours the web for pricing info on thousands of secondary-market concert and sports ticket sales (sites like StubHub, RazorGator, TicketsNow, etc.), in order to forecast pricing trends for events by algorithmically crunching the data with outside factors that realistically affect demand, including post-season implications, weather, and competing concerts/events, causing the site to implode when the Hotel California 35th Anniversary tour hits Philly the same day the Birds are playing. Search by city/artist/venue/team and SG'll display a list of relevant events; click each for a summary of the research conducted, including a line graph charting recent pricing history, SG's trending forecast for prices up to the day of the event (seven levels ranging from "sharp increase" to "sharp decrease") and recommendations to "buy now" or "wait to buy"; they currently claim about 80% accuracy, exactly on par with your aim in the men's room. Geek also offers one-click access to the most inexpensive tickets currently online for any event, redirecting buyers to the appropriate broker; for those who choose to wait in the hopes of scoring cheaper tix, Geek offers to notify users via email when things hit rock-bottom, a service that could've been infinitely useful to Chris Farley.
Although it's starting out handling MLB games and concerts, Geek plans to soon add NFL tickets to the service -- of course, you're welcome to write in and tell them what you want, what you reallyreallywant.
