A li Erdemoglu is a Turkish industrialist who, along with his brother Ibrahim, owns and runs SASA Polyester, one of the world's leading producers of polyester fibers, filaments, and polymers. The brothers' journey into big business began with Erdemoglu Holding, a carpet manufacturing company founded by their father. They transformed the family business into a major player in the carpet industry.

Their most significant business move came in 2015 when they acquired SASA Polyester from a major Turkish conglomerate. Under their ownership, SASA has undergone a massive expansion, with the brothers investing billions of dollars to increase its production capacity and technological capabilities. This ambitious investment program has turned SASA into a cornerstone of the Turkish chemical and textile industries and a major global competitor. Ali serves as the chairman of the parent company, Erdemoglu Holding, guiding the family's vast industrial interests.
