Demetris and his team (Dimitrios Dessylas, Rox Kulliye and Spyridon Michelakis) chose to combine tourism with philanthropy in their proposition for BattleHack. Their idea is that visitors may use the PayPal platform to donate an amount of money in exchange for hearing and viewing a story about historical monuments of world heritage in Athens. Receivers of the donations will notify the donor about the progress of their cause via social media and SMS. Demetris, a PhD researcher from Ioannina University, talked a lot about his important startup experience abroad and also Rox came in to praise the high level of the Greek human capital in the field.
