There are now 90 tech hubs/labs in 28 countries around Africa.
A current 2014 map of tech hubs in Africa, done by the World Bank, iHub Research and BongoHive. Read the original article here, “Tech hubs across Africa: Which will be the legacy-makers?” by Tim Kelley.
As exhaustive as this is, I think there are a few missing. I believe that there are two new ones in Zimbabwe not showing up, Muzinda Hub and Hypercube Hub (though, I’m not 100% that they’re up and going as running spaces). All that to say, more keep cropping up, and that’s a good thing.
+ JoziHub, which is also missing.
