About the founderFounder
Efecan Başöz founded Sirkhet in 2017 after starting his career in digital marketing in 2013 and working across retail and technology. An industrial engineer by training, he built the agency around one belief: marketing is a frontier, and the best results come from exploring it with data rather than guessing.
He still works hands-on with clients, and he leads the development of Sirkhet's own MarTech products, Kong Metrics and Sentimaps. The agency's name is a quiet tribute to Turkish: to an English speaker, "Sirkhet" sounds like şirket, the Turkish word for company.
