Young entrepreneurs are changing the face of Africa. I set out to produce a list of the 30 Africans under 30 years old who are making the most dramatic impact across the continent. To do so, in November I enlisted an outside panel of 12 judges from across Africa to help identify this group of outstanding entrepreneurs and innovators under the age of 30.

The 30 young African entrepreneurs, disruptors and innovators featured on this list are impatient to change Africa. Together, they represent the entrepreneurial, innovative and intellectual best of their generation.

Of course, this list is by no means official or exhaustive, but this is the closest you’ll get to a definitive list.
