Nayden Kostov

Nayden Kostov was born in Bulgaria and has lived in several different places throughout his life, including Belgium, Germany, and Iraq, before settling down in Luxembourg with his family. Kostov's insatiable appetite for facts and unrestrainable intellectual curiosity have greatly influenced his academic background and career. He holds Master's degrees in Greek Philology, German and English Translation, and has also graduated in Crisis Management and Diplomacy. Most recently, Kostov completed an MBA.

Kostov's career has been as diverse as his interests, with roles ranging from an army paratrooper and military intelligence analyst to a civil servant with the European Commission, and currently, a clerk performing financial tasks in a major bank. He is also a member of MENSA and enjoys reading, traveling, and scuba diving. Kostov's love for sharing interesting facts with his family led him to write the book 'Fascinating Facts for the Whole Family,' which he wrote in collaboration with his eight-year-old son, Pavel, who provided the illustrations and helped handpick the facts.
