I’m glad you enjoyed your visit to Nigeria, Emmanuel. I have visited Ghana only once in my entire life and it was the perfect tempo switch at the time.
There are about five universities (in terms of ubiquity) one should keep in mind when thinking of the human resources milling around the startup space:
Babcock, Covenant University, one of the FUTs (can’t remember if it’s FUTA, FUTO, or both of them even), Unilag and OAU.
I’m from Uniben myself — and I’m always glad to meet fellow graduates like Oo Nwoye!
