Sidney Rema
Sidney Rema is the co-founder and CEO of Sanifu (YC S22), a Nairobi-based startup that uses AI to pull sales orders out of emails, WhatsApp messages, PDFs and even handwritten notes and drops them straight into ERP systems. A University of Nairobi medical student who kept building companies instead of finishing his degree, Rema spent years in small-business banking and payments before co-founding Sanifu with Phelix Juma and Bernard Momanyi. The company grew out of Patika, a marketplace the team started as a food-ordering app called MealTime, and now works with African manufacturers and distributors to cut order processing from minutes to seconds.
Molly Heacock
Molly Heacock is the incoming CEO of Untold (formerly CARE for AIDS), an Atlanta-headquartered global nonprofit helping people living with HIV move toward a life beyond AIDS through holistic, community-based, faith-integrated care. A public health practitioner who spent a decade as COO and Managing Director before stepping up to lead, she has helped scale a model that pairs medical adherence with economic, emotional, and spiritual support across dozens of communities in Kenya, Tanzania, and beyond. She relocated from Atlanta to Nairobi in 2019 and built her career on the conviction that local, indigenous-led staff and dignity-first care change long-term outcomes.
