Marlon introduced the Mxit platform – here are the quick facts: Mxit has over 50 million users making it world’s 9th largest social network, and the largest in Africa. It started in South Africa in 2005 initially spreading virally as a free messaging platform. Since then a lot of other applications have also been developed based on it, for example apps providing information, entertainment, counceling, communication, education. However, Mxit is not yet widely adopted in East Africa: Tanzania has about 25 000 Mxit users and for example Kenya about 100 000. This is something they are looking to change.
