How Ian Griffin and Dirk Stewart Set Up Seat Frog

Ian Griffin and Dirk Stewart founded the travel ticket app, Seat Frog. It allows you to buy train tickets on your phone and then take part in live online auctions for any first class carriage seats that remain empty shortly before travel. Last year it hit revenues of more than 20 million pounds, just over 25 million dollars. The pair are both first time entrepreneurs who took the business plunge together.
