Founding Partner and Creative Director of Madison, an Ecuadorian independent creative agency. Sebastián began his professional career at the age of 21, although he had been writing advertising since he was in high school. The first agency where he could find himself as a copywriter was Ogilvy Ecuador, then a short 2-year experience as a screenwriter, and finally returning to advertising copywriting at Punto99, managing large Ecuadorian and foreign brands such as KFC, Baskin Robbins, Juan Valdez and others. After having gained enough experience in writing and creativity, he decides to form Madison, the agency that catapulted him to be recognized in several international festivals such as Wina, El Ojo de Iberoamérica, Fepi, Lux, Luum and others.
