In Johannesburg, South Africa, there are a small but growing number of shared office spaces in which sole proprietors and small businesses rent a desk and other services. For small business owners and start-up companies, this route not only provides cheaper overhead for workspace, but it also helps entrepreneurs network. The OPEN Collaborative Workspace is on the fourth floor of a building in an artsy, up and coming area just south of downtown Johannesburg, in a neighborhood called Maboneng.
