"With the second volume in the series Digital Innovation Made in Africa, we want to raise awareness of the enormous potential of young entrepreneurs in Africa. In this edition, the Tech Entrepreneurship Initiative Make-IT in Africa presents innovative initiatives and projects that have attracted attention in two different ways. In October 2017, the World Summit Awards (WSA) Grand Jury meeting took place in Berlin. As a contribution to the United Nations World Summit on the Information Society (WSIS), each year since 2003 the WSA has recognised the world’s most innovative digital applications and solutions for implementing sustainable development goals. The African winners and best entries for 2017 make up half of the 20 companies presented here. The other half is made up of innovations selected by the members of the Make-IT Alliance. In cooperation with technology hubs in Kenya and Nigeria, investors, German chambers of commerce abroad and startup networks, Make-IT launched the Make-IT Accelerator in Africa in December 2017. The nine-month support programme for innovations of particular importance for sustainable and inclusive development is being implemented in Nairobi and Lagos." (Foreword)
