Fast-growing "better burger" chain BurgerFi signed its first international development agreement, with Mexico-based EFIT SA DE CV. The deal calls for the opening of 40 BurgerFi restaurants in Mexico City and surrounding areas over the next 5 to 7 years.

"We have established a reputation for strategic growth, and believe that the EFIT SA DE CV team has the genuine passion, industry experience and deep infrastructure to be our first partner to expand BurgerFi's presence internationally," says CEO Corey Winograd. The company has operated other U.S.-based chains in Mexico, including Wingstop and Domino's.

South Florida-based BurgerFi, which touts burgers free of growth hormones, steroids and antibiotics, has 69 restaurants in the U.S. and expects to reach 100 units nationwide by the end of this year. Gross sales in 2014 were $66.4 million, up 114 percent from 2013.
