Stephan Bayer came up with the idea of sofatutor in 2008 while he was a student at the Humboldt University in Berlin, Germany. The idea arose while he was preparing for a mathematics test. To help him understand the subject matter better, he spontaneously shot a short film with his new camera and shared it with his fellow students. The response was so positive that the idea of building a learning platform with videos never left him. Today, sofatutor.com is an integral part of the educational landscape in Germany. More than 100 employees attend to content, innovation, and further development every day.
