Denver’s main telecommunications company, U S West Inc., recently cut a seven-figure check for 21-year-old Yale senior Stewart Ugelow — a former summer intern at this newspaper — for a 35% stake in his Internet Web site, which publishes news-feature stories and data such as TV and concert listings for college students. Student.Net Publishing LLC is less than two years old, and none of its six founders has any prior business experience. “We don’t have anybody on staff yet old enough to rent a car. That’s one of our goals for our next hire,” Mr. Ugelow says.
