I’ve gotten to know Gustav Praekelt over the last few years after we first met up at PopTech in 2008. He’s one of the most astute businessmen I know on the continent, and his ability to grow out his business into the giant it is in the messaging and communication space is proof of that. The Praekelt Foundation leverages the same infrastructure that he’s built out on the for-profit side of what he’s done, and is making a big impact, at scale. You can watch a video of him talking about his projects here.
