Tuudo offers flexible visibility. Reach out on a global scale, or tighten your focus based on geography or fields of study.

Tuudo is students' tool in everyday life. They carry it along, they use it almost all the time, come rain or shine, day and night.


Many of the best ideas have their foundations in personal needs, skills and wills to solve a problem. Tuudo is no exception. Tuudo solves the need to pull together scattered information and tools that help students achieve more in their studies and in life in general. The app was conceived by three IT students in the University of Oulu in 2015.

In order to offer the best possible solution to the problem, the three students decided to launch a startup, Caleidon Ltd, which is now developing Tuudo into a global service. Along with the founding members of the company, Caleidon Ltd and its internationalization are backed up by senior investors and their experience.
