Eleven promising business ideas emerge from Bonnier Hack Day, with one clear winner.
After 24 hours of solid creativity, Bonnier Hack Day ended with a round of three-minute pitches from the 11 teams that made it through the night, still fired up despite the long hours of work.
A team from Sydsvenskan won the day, with their "Citypedia" concept, which combined data on any city from gowalla/4sq, Twitter and Google along with users' own ratings to create a city wiki with an app for iPhone and advertising. Team members included Per-Olof Bondesson, Johannes Fosseus and Sara Johannesson.
