Mthokozisi Mzingaye Moyo  is an innovator who uses his Civil and Water Engineering background to address problems in the water and energy sector. Currently working on his two companies, WasteMoney and Ulwazi Technologies, which aim to merge the ideologies of a circular economy and data-driven decisions. This is done to maximise resource value (especially water), while minimising environmental impact so that both the economy and environment can thrive. This proactive stance is also fueled by the rate of problems arising in the world which need solutions conceptualised and deployed and a faster rate. He is a firm believer of team work (the more diverse the team the better) and is also passionate about service above self which he enacts through sustainable projects such as teaching rural kids bee keeping with the Rotaract Club of Matopos.

Jessica Ertel is an emerging data scientist interested in the ways data science can be used to address complex environmental and humanitarian challenges. Her work experience spans different disciplines and sectors, reflecting an interest in continually growing new perspectives.
