Churchill Nanje Mambe has been writing code since 2004, but it wasn’t until he built Njorku.com in 2011 that he became well known in Africa and the rest of the world. This included a profile on Forbes.

Njorku is a fast-growing career and recruitment platform for Africans, which retrieves pages and job advertisements. This provides a simple interface for job seekers to search through and filter jobs. “I never saw this coming,” he tells me, because today, Njorku receives CVs from people who live in the Philippines, Bangladesh, China, Mexico, Pakistan, Hungary and many other countries, and all these people want to work in Africa. Currently, Njorku serves seven African countries (Cameroon, Nigeria, Kenya, Ghana, Uganda, South Africa and Egypt).
