She’s co-founder of Organization Unbound, a global community of practice based out of Cape Town that explores how social purpose organisations can live out, in their daily functioning, the changes they are seeking to create in the world, and by doing so deepen their social impact. In her own words, Tana craves, “dialogue, community, and crossing societal divides”. She’s also, “an avid fan of bicycle-centric cities and excited to see the use of bicycles as a form of transportation gaining momentum in Cape Town”.

Dr Nosakhere Griffin-EL is a self-confessed dreamer and lecturer at the University of Cape Town’s Graduate School of Business. From a traditionally socially and economically oppressed background in America, he’s worked extensively with oppressed communities on realising their value and reaching their potential. All of this while caring for his eight-month old baby boy with his soulmate and fellow senior lecturer, Eliada W Griffin-EL.

He started with a PhD in Nuclear Physics, then worked as the Shuttleworth Foundation Fellow for Open and Collaborative Resources. That’s when he transformed the Free High School Science Texts project, which he co-founded, into open source educational resource company Siyavula – an apt Nguni word that means “we are opening”. Mark is the CEO of Siyavula. That’s when he’s not working as a company physics expert, administrator, blogger, IT nerd or anything else.
