SAO PAULO, June 14 (Reuters) - The chief executive of

Zamp, which operates Burger King restaurants in

Brazil, Ariel Grunkraut, will leave his position on June 28, the

firm said in a securities filing on Friday.

Grunkraut was one of the founding partners who established

Zamp in 2011, and led the sales, marketing and technology

departments before he took on the CEO role two years ago.

His departure comes a few days after Zamp agreed to buy the

rights to operate the Starbucks brand and some stores

in the country.

"The company and the board of directors wish Ariel every

success and extend their best wishes for his new challenges,"

Zamp said in the filing.

The firm did not offer any information on a possible

successor to Grunkraut.

Zamp, which is controlled by Abu Dhabi state investor

Mubadala, operates Burger King and Popeyes

restaurants in Latin America's largest economy.
