By Zachary Fagenson MIAMI (Reuters) – Silicon Valley need have no fear, but look out for the latest upstart to enter the tech arena: Miami. A south Florida millionaire investor is seeking to turn the city into a science and technology startup hub with a focus on the Americas, leveraging the regions better-known assets – beach condos, low taxes and capital flight from all over Latin America – to attract a new generation of Hispanic entrepreneurs. More than 5,000 people have been lured to a pitch this week by Manny Medina, attending a five-day tech conference he founded titled eMerge Americas. More than 150 speakers discussing everything from serial entrepreneurship in Latin America to groundbreaking medical technologies, organizers said.
