Our Leadership Team
Konstantinos (Kostas) Tsiakalos
Simulation-CAX-WAR GAMING
After a long run in the army I retired as a full Colonel back in 2011. From my career in the Hellenic Armed Forces I earned a lot. Leadership, teams management, human resources administration and management, budget management and many more. Because of my roles were expanding in various fields of expertise, from engineering and explosives to software development and big data management to modelling and simulation, I can combine a serious set of certain knowledge and experience which has become my main advantage in my business career. Together with the exceptional knowledge that I gained from my Master in Statistics and Operations Research I was able to design, develop and run a set of complex and unique projects that added value to my business partners, companies and customers. The most important that I can present is the methodological way of developing succesful and innovative projects. The Computer Assisted Exercises methodology, the methodology of Active Babies & Kids, the Youth Orientation System "Epicuros" and the History Educational System "Herodotus" proove my capablity to generate innovation and spread knowledge. My involvment with the online media was also succesful and extraordinary as together with my partners we have developed a comprehensive approach for on line media by all means. Even more, I am proud for my involvement with financial projects which were developed by the extensive use of game theoretical models which is my main area of research. The decentralized economy, cryptocurrencies, microfinancing and the innovative products and services for supporting strategic investments can really enrich the financial ecosystem of the present and the future. I am also proud for my achievements in the NATO environment where except my contribution to a significant set of NATO exercises, together with my colleagues we managed to be awarded several contracts for supporting NATO training events. For both personal and professional development: The sky is the limit!
