Later, he joined Hot Sun Foundation, a Nairobi-based nonprofit organization offering training in filmmaking to the youth in Kibera, where he worked as the program manager. In 2011, he co-founded the Slum Film Festival. The idea behind Slum Film Festival was to create a platform that recognized the stories and filmmakers from slums, connecting them to the international film-festival circuit. In 2014, Josphat joined What's Good Studios as post-production producer. Josphat is passionate about arts and youth from slums, and has formed platforms that engage these youths. Currently, he is working on a proposal to form a center that supports arts in slums. With the Fellowship, he hopes to interact, network, and partner with like-minded parties to see this project become a reality.
