How do we create a truly pan-African event?

Each Stream event takes a year to plan and much of that time is spent creating the invitation list. We look for the right mix of entrepreneurs, media and tech companies, brands and agencies. We try to balance gender. Race. Nationality. This year we have done pretty well on gender - with a 40/60 ratio of women to men (up 5% from last year). But we have fallen short on diversity. Our target for Stream Africa to have at least 50% non-SA guests. We are below target! And this is despite positive descrimination, 1-by-1 follow up and electing country ambassadors for each key market. What more can we do? & how can we make Stream Africa 2017 (even) better? All ideas welcome!
