Register YOUR TEAM Now!

StCatsHacks is Athens’ first inter-school hackathon, bringing together primary and high-school students passionate about STEM for a two-day coding challenge at St. Catherine’s British School. Teams of up to five, guided by mentors and using APIs, will design innovative programs judged on creativity, functionality, and real-world impact. Now in its 8th edition, the event draws inspiration from Aristotle’s eudaimonia—human flourishing through knowledge and virtue—aligned with the UN’s 17 Sustainable Development Goals (SDGs). Theme: “From Aristotle to AI: Innovating for the 17 UN Goals.” Students are invited to use AI to create solutions that advance the SDGs—tackling issues from poverty and education to climate action and peace. Echoing Aristotle’s belief that knowledge should serve humanity, StCatsHacks challenges young minds to turn ethical ideas into technological innovations for a thriving future.
