A small team of independent entrepreneurs developed two Massive Open Online Courses (MOOCs) on sustainable development that attracted over 400 participants. This article describes the original intentions and formats of the MOOCs as well as their actual performance. With little publicity, the courses revealed strong buy-in by the participants and resulted in both a high percentage of completion and degree of satisfaction. Based on this experience, we believe that MOOCs have the potential to provide the impetus needed in initial and vocational training to respond to the challenges of capacity development, highlighted in the Post-2015 Development Agenda and in reflections on Africa like the "Madavo Report" (2005) on capacity building in Africa.
