Recently we had the privilege of judging and sponsoring the UC Davis business plan competition. The objective was for undergraduates teams to come up with a mobile application concept/prototype and a business plan to bring it to market.
There were 7 teams that made it to the finals. They were all amazing in different ways. Concepts ranged from gamification/socialization of your fitness goals, to tracking how your daily purchases and transportion decisions effected your carbon footprint, to optimizing markets via peer to peer transactions.
