Demian Bellumio, chief operating officer for Senzari, a Big Data content recommendation company based in Miami, seems in motion even while calmly answering questions seated at a desk in the company’s conference room. It’s late summer and part of this, no doubt, is because today he’s waiting for a call from a potential sponsor for this year’s SIME MIA, a two-day conference that merges entrepreneurship, media technology and the arts.

Born in Argentina but raised in Miami, Bellumio has been instrumental in organizing events such as the MIA Music Summit, which brought together people in music and technology, entrepreneurs and investors, and also bringing SIME, a Europe-based event, to South Florida. Last year’s gathering was a partnership between SIME and MIA Collective, of which Bellumio is a founding partner, with support provided by Knight Foundation through 2015. But on this day, he says, more sponsors are needed. And if a potential backer is interested, he’s happy to talk. As it develops an ecosystem for high-tech entrepreneurs and investors, Bellumio is one of Miami’s most enthusiastic pitchmen. He has a success story to tell—and a passion for his hometown.
