I spent this past February in Kenya working with a tech startup and all of my expectations about technology in Africa were completely shattered. Nearly everyone I met (both in Nairobi and in smaller towns) had smartphones with data plans, used mobile banking and were very willing to try out the latest technologies. I used Uber to commute to the office every day and get around the otherwise sketchy parts of town at night, the service is doing so well that traditional taxi drivers were rioting on the streets. Sub-Saharan Africa is a hotbed of opportunity ripe for disruption.
