It's early to hire a regional CEO starting with an MVP. After launching more than 4 ventures in Latam; I've learned that the best ROI is to enter with a US based consultant or team that knows and understands Latin America as can help you save time, effort, and money. It would be ideal to pick two or three Latam countries and identify the market opportunity. Then, prepare a quick market assessment or SWOT to understand the entering barriers and what is needed to start generating some "fans" or sales. Once you have created some activity locally and have maybe identified some potential partners; it could be a good idea to find someone that could help you manage the future growth. You might find that offering 40% of revenue share plus a % in the patent may be too "expensive". Latin America works well when there is a long term plan (+8 to 10 years); short terms plans are not too profitable sometimes.
