About.
Mahmud Filoğlu stepped into digital marketing while studying Business Administration, taught in English, at Istanbul Bilgi University. Before founding Roicool, Mahmud had already worked with more than 15 clinics in the health sector. Over the past six years Mahmud has worked closely with brands, run campaigns and kept asking "how do we do this better?" That experience led to Roicool, an agency built around measurable results, where the aim is for brands not only to be visible online but to create real value.
