African Dream - Olivier Nizeyimana
When Olivier Nizeyimana was a student, the journey to Rwanda's National University would sometimes take him ages, so he thought it would be a good idea to start a bus company that made punctuality one of its core values.
"People learn from problems. Sometimes in business, a problem can be an opportunity," he told the BBC's series African Dream.
In 1999, a year before graduation, he launched his Volcanoes Transport Company.
He started the company with two buses and now has more than 60. And it is expanding internationally.
