Advertising goes social. Zooppa is the leader platform for user-generated advertising, inspired by the principles of crowdsourcing and the dynamics of social networks, that is revolutionizing the way brands engage consumers. The brands launch on Zooppa their creative contests and the community members create their proposals based on the brief published online. Users can upload videos, printed ads, radio ads, banners and concepts/screenplays. For each contest the companies put at stake money prizes and users compete to win them. Prizes are assigned by the brand, the Zooppa staff and by the community itself. The brand gets from Zooppa creative contents, viral effect related to the contest model, community engagement and feedback concerning the product/brand. By today Zooppa hosts more than 150 creative contests in three countries: USA, Italy and Brazil. The community is over 100.000 users growing day by day and increasing the quality of the contents produced.
