Andronikos Koutroumpelis holds a degree in Informatics from the Athens University of Economics and Business, with a specialization in operations research and knowledge management. He works part-time as a technology manager at the Edu4u Lifelong Learning Centre.
He worked at the fact-checking organization Ellinika Hoaxes (EH) from December 2017 to August 2023.
He participated in the legal establishment of the EH company and worked in roles involving technology solutions, European programmes, fact-checking articles, data journalism, and scientific-article editing. In that context, he also took part in a series of interviews, presentations, and seminars, including with ERT, TEDx University of Crete, and NCSR Demokritos.
From 2019, he also participated in the launch in Greece of Facebook’s, now Meta’s, Third-Party Fact-Checking programme (TPFC) on its platforms.
At the same time, he was responsible for the technical development of the first Greek false-news warning application, Greek Hoaxes Detector. He also adapted into Greek the Bad News Game, a game created by academics at the University of Cambridge to help inoculate players against misinformation.
He also participated in the first steps of the Mediterranean Digital Media Observatory (MedDMO), as well as in the European AI4Trust programme, which aims to develop artificial-intelligence systems for detecting and countering misinformation.
During the COVID-19 pandemic, he worked extensively on related pseudoscientific misinformation and on accurate public information. In this context, he spoke at the 13th Panhellenic Conference of the Hellenic Society for Infection Control, as well as at the 18th Postgraduate Seminar of the Third Department of Pediatrics of the National and Kapodistrian University of Athens.
After leaving Ellinika Hoaxes and co-founding FactReview in 2023, he has participated in almost all activities of the new organization.
A representative milestone of this activity was FactReview’s European recognition as Greece’s first trusted flagger for illegal content (DSA Trusted Flagger) in November 2024, followed four months later by an invitation to the European Parliament to present a report on the systemic risk of scams on social media.
Since late 2022, he has observed that new developments in Generative Artificial Intelligence (GenAI) implied radical changes in the field of information integrity, both negative and positive. Since then, he has studied, experimented with, used, and participated in the related developments and debates on a daily basis. Among other roles, he is co-responsible for technology in the related Global Fact-Check Bot consortium.
He considers unified literacy in media and GenAI to be necessary. In this context, he has delivered a series of public seminars, including in cooperation with the Goethe-Institut and the Onassis Foundation. He has also delivered more specialized related presentations to the Hellenic Telecommunications and Post Commission, the Greek Diplomatic Academy, and the International Fact-Checking Network.
He considers fact-checking to be inseparably connected with responsible journalism, and is a member of the Journalists’ Union of Macedonia and Thrace (ESIEM-Th).
