Sebastian Mejia grew up in Cali, studied in Spain, and worked in Turkey and New York before helping build Rappi, and that path shaped his focus on resilience, identity, and purpose alongside a strong belief in execution and building talented teams. At Rebel Fund, he looks for companies that work as full systems rather than single features, often in messy, undigitized categories like groceries, delivery, and payroll, and he prefers to stay closely involved in the companies he backs rather than investing from a distance.
