Facebook CEO, Mark Zuckerberg and his wife, Priscilla Chan, has invested about  $24 million into an African startup called Andela, through their foundation Chan Zuckerberg Initiative.

Andela trains prospective software developers in Nigeria and Kenya. The founder, Jeremy Johnson has been sharing a pretty incredible story about how he had started Andela, how it was helping to train thousands of programmers in Africa, and the impact it was already having on young people in a region where training and education for IT can still be tough to find.

Andela business model centres on vetting applicants and then trains them and finds them project-based work for international tech companies. They learn while getting paid for doing IT work, gaining more practical experience. And of course, companies get lower-cost labour to handle specific jobs.

Mark Zuckerberg is one of a number of tech moguls who have promised hefty portions of their wealth for charitable purposes. That group also includes billionaires such as Google co-founders Larry Page and Sergey Brin and Microsoft co-founder Bill Gates
