Three students had time on their hands in the summer of 2009 when their university lecturers in Nigeria went on strike.
Instead of slacking off, Ayodeji Adewunmi, Olalekan Olude and Opeyemi Awoyemi started an online job search company.
Five years later their start-up, Jobberman, has got a multi-million dollar valuation, employs 125 people, and is still growing.
