KenCall is one small reason that Kenya’s economy grew 6 percent last year. Yes, Kenya still has all the ills of other African states — from AIDS to abject poverty. But Kenya also now has a democratically elected government that is learning to get out of the way of Kenya’s entrepreneurs and to get them the bandwidth they need to compete globally. It’s way too early to declare Kenya an economic “African Tiger,” but something is stirring here that bears watching — and KenCall is emblematic of it.
