There are loads of podcasts about entrepreneurship, setting up a business or start-up, being your own boss and making money. According to the American business magazine Forbes, up to 9 in 10 start-ups fail, and the number is thought to be even higher in Africa.

BBC Africa’s business reporter in Lagos, Nigeria, Nkechi Ogbonna, explains what a start-up is and some of the reasons why start-ups fail. We also hear about some of the sectors where start-ups are doing well.

African entrepreneur and YouTuber, Joseph Don, from The Entrepreneurs Connect Show, sets out the challenges some businesses in Africa face - and gives his top tips for starting and maintaining a successful business.

And Nic Rawhani, the South African founder of Vula.VC, a company that uses AI to help start-ups find and apply for funding, tells us how people can pick themselves up and learn from their mistakes if their business doesn’t work out.
