SeatGeek is an event ticket marketplace and aggregator of sports, concert, and theater tickets. SeatGeek allows both mobile app and desktop users to browse events, view interactive color-coded seatmaps, complete purchases, and receive electronic or print tickets. The list of events on SeatGeek shows prices for ticket inventories aggregated from ticket exchanges such as TicketNetwork, TicketsNow, and Razorgator. Tickets are sorted using the companys DealScore algorithm which finds the combination of best available price and seat location for a particular event. Historically, SeatGeek provided price forecast information in a similar manner to Farecast, an airline ticket aggregation and forecasting site purchased by Microsoft in 2008. SeatGeek has seen success in the mobile space, adopting Apple Pay to provide seamless purchase and payment. SeatGeek was founded by Russell D'Souza and Jack Groetzinger from DreamIT Ventures, an early stage startup accelerator program in Philadelphia and launched in September 2009 at TechCrunch50 where it was named by VentureBeat and CNET as one of the top 5 companies from the conference.
