Commuto.com is an online service that allows users to trade and swap items for free within their communities to reduce student expenses and make school more social. It has over 4,000 registered users and has been featured in several publications. The company plans to launch campus campaigns and develop partnerships and social features. Revenue will come from advertising initially through Google AdSense and later through in-house advertising. Social networks now reach older demographics and represent an opportunity for 12% of online advertising. Commuto.com could succeed by addressing a new market, but risks include security issues, universities restricting use, and competitors copying the idea.
