Matt Raible - Matt Raible is a Montana native who grew up in a log cabin without electricity or running water. He would hike to school a mile and a half everyday (skiing in the winter), and would arrive home to a very loving family. "The Cabin" is a beautiful place that will always be near and dear to him. Even without electricity, his father connected them to the Internet using a 300 Baud modem, a Commodore64, and a small generator. CompuServe was the name, slow was the game. Matt became inspired by the Internet in the early 1990s, and has been developing websites and web applications ever since. He graduated from the University of Denver in 1997 with degrees in Russian, International Business, and Finance.
