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.
Ricardo Flores is the co-founder and CEO of MiChamba, a startup that turns WhatsApp into an AI-powered management platform for deskless teams in construction, logistics, hospitality, and industrial services across Latin America. A kid who worked scorching El Paso roofs before heading to Georgetown and Wall Street, he left finance and an early seat at fintech Wealth.com to build software for the blue-collar workforce he came from. Less than a year after launch, MiChamba raised a $2.25M pre-seed led by Wollef and signed names like Pemex, Hilton, and Repsol, betting that for the 3 billion people who run their work lives on WhatsApp, management should live there too.
