busuu is the world's largest social network for language learning with more than 50m users. On a daily basis, up to 120k users sign up to our platform and our main growth is coming from emerging markets such as China, Brazil, Russia and Turkey. Users can access audio-visual language courses in currently 12 languages. They can practice their language skills with native speakers of the community via an integrated video-chat application and peer-to-peer text corrections. On busuu, every user is not only a student of a foreign language but also a tutor of his/her own mother tongue. The vision of busuu is to revolutionize the way people learn new languages.
