Your question is answered by Ayisi Mekatiani in a paper entitled "Navigating the risks and opportunities of investing in Africa".

Mr Makatianiis the CEO of AMSCO{The African Management Services company}He possesses extensive management .enterpreunerial and board level experience,having co-founded Africa Online among others.
