Marcela co-founded and headed Open Streets Cape Town from 2012 to 2019, an organization which inspired new thinking around the use of Cape Town's streets and led to similar initiatives in other African cities. Since then, she has continued to work on mobility related issues, while expanding to, and publishing widely, on new areas such as public space and food systems.

Up until 2017, Dustin built and led the Social Justice Coalition, one of South Africa’s key social movements for greater urban equality during that period. After leaving the SJC, he began a global activist fellowship with the Social Change Initiative in Belfast and then continued to expand his consulting and independent work internationally.

Below are some examples of our work, as well as further down, a collection of pieces profiling us.
