Born to a Sephardic Jewish family in Istanbul, Andic's family emigrated from Turkey to Barcelona, Spain in 1969 where he and his brother Nahman began selling hand-embroidered T-shirts and clogs. They opened shops in Barcelona and Madrid, first selling their own brand (Isak jeans) and then stocking other brands. In 1984, he joined with fellow Entrepreneur Enric Cusí and his brother and re-denominated all their stores under the name Mango. Andic chose the name "Mango" after tasting the fruit on a trip to the Philippines and for the fact that the word is pronounced the same in every language.
Andic is divorced from Neus Raig Tarragó with whom he has three children: Jonathan Andic(born 1981) who was named his successor in 2012; Judith Andic (born 1984), who also works for Mango; and Sarah Andic (born 1997). Andic lives in Barcelona.
In 2006, Andic was appointed the Director of Banco Sabadell and in 2012, he became its single largest shareholder with a 7% ownership interest. According to Forbes, Andic has a net worth of $4.8 billion, as of January 2015. Mango has 2,400 stores in 107 countries.
