There are 120 million middle class people in Africa with smartphones, but only 12 million have broadband at home. Wifi.com.ng builds solar Wi-Fi transmission towers that can support 1,500 homes with Wi-Fi at 30 percent of the price of mobile data. It now has 35 towers and earns back the infrastructure cost in 7 months. The startup has $1.2 million annual recurring revenue, and is growing 25 percent per month. Africa doesn’t have the phone lines or roads to run traditional cables, and satellites and drones won’t work in dense cities, so Wi-Fi is the answer. Wifi.com.ng believes it can become the Comcast of Africa.
