Initially focused on Miami, the firm has expanded its reach across North America and Latin America, evolving to invest globally in 0 → 1 stage companies (pre-seed and seed). Their founding vision includes accelerating Miami’s rise as a tech hub by attracting and integrating founders from major startup ecosystems like Silicon Valley, New York, and Los Angeles[2][3].
