Sequoia has only made a half dozen Latin American investments - including Nubank and Rappi - but Sonya Huang, a partner at the venture capital firm, said it planned to back one or two companies a year, in sectors such as finance, e-commerce, health and education. "The region is very different from the U.S. or Europe, but there are some big theses which have proved right globally - like digital or mobile-first banking - and they can be applied in the region," Huang told Reuters.
