An annual competition for start-up entrepreneurs located in Johannesburg.
In South Africa, the development of ICT is seen as a lever for improving productivity and green growth in an urban environment. In 2014, Johannesburg council launched a hackathon to elicit innovative ideas in digital formats to resolve the challenges of the city.
It is a capacity-building programme to support the creation of jobs and entrepreneurial development, particularly of small businesses. The ten winning participants are selected following a competition during which they have access to mentoring, technical support and networking. The first prize is 1 million rand (almost 70,000 euros); the following two are 350,000 rand each.
This initiative grew in partnership with the University of Witwatersrand (Wits), the Joburg Centre for Software Engineering (JCSE) and Seed Academy business school.
