Experts say that Cuban entrepreneurs are eager to generate more business.
"A lot of Cuban entrepreneurs are being successful, and they are excited. Some of them are making money hand over fist," said Richard Feinberg, author of forthcoming "Business: Building the New Cuban Economy" and senior fellow in the Latin America Initiative at the Brookings Institute.
The number of self-employed Cubans, or cuentapropistas, rose from 150,000 to 500,000 between 2010 and 2015, revealed the World Policy Journal. The adult population of Cuba is 11 million, according to the CIA World Factbook.
"Havana and other cities are blossoming with new restaurants and bed-and-breakfasts; transportation services, including taxis and trucking; as well as private construction firms and appliance-fixing shops," Feinberg said.
The majority of start-ups recently launched by Cubans have centered around tourism and the service industry, but there is a growing cadre of internet-based content and publishing companies in Cuba, according to multiple experts.
"I think there are a lot of other Cubans who want to get in the game," Feinberg said.
But questions remain on how new start-ups will function.
"To get the kind of high-growth entrepreneurship that can really create high-quality jobs, have added value and drive socioeconomic prosperity, you're going to need the institutions to get on board," said Northwestern University's Kellogg School of Management professor Benjamin Jones. "Will start-ups be able to scale?"
