Juliana Rotich

Kenya. Rotich co-founded Ushahidi, open-source software for crowd-mapping reports during Kenya's 2008 post-election violence, then BRCK in 2013, a rugged internet router with its own battery built for places where power cuts and patchy networks are normal. BRCK later moved into free public Wi-Fi on Nairobi's matatu minibuses. Designing hardware around local infrastructure rather than importing it is the point.
