Seppo.io is a Finnish start-up that is specialized in game-based-learning. We have created an interactive platform called seppo, which allows teachers to take full advantage of mobile technology and game based learning in education. Seppo is a web application that allows teachers to design, build, and share educational map based games. Games build on Seppo can be used to support learning, to increase student participation, and to incorporate exercising into a school day in an innovative and motivating manner.
