Best Startup Events in Greece 2026–2027: Calendar from November 2026 to October 2027
November 2026
The Archimedes unit of the University of Athens (NKUA) holds its Student Open Innovation Competition in early November: the English page says 4–6 November, the Greek page 6–8 November. Applications closed on 30 September, and it is for NKUA students, so it matters mainly to companies that set challenges or hire from the university.
GenAI Summit, Athens: 16 November 2026
The organisers expect more than 5,000 attendees and 200 speakers; the speakers page names Prime Minister Kyriakos Mitsotakis, Najwa Aaraj (Technology Innovation Institute, Abu Dhabi) and Elena Pittarokoili (OpenAI). With that many AI teams in one place, it suits founders looking for enterprise customers. See our AI events list.
Voxxed Days Thessaloniki: 20–21 November 2026
The tenth edition of a conference run by developers for developers. It is not a startup event, but it gathers developers from across northern Greece, useful if you are hiring a CTO or engineers. See our developer tools events list.
Digital Economy Forum, Athens: 23 November 2026
Organised by SEPE, the Federation of Hellenic ICT Enterprises. The speakers page lists the Minister of Development and the Minister of Digital Governance; go to learn where public money for digital and AI projects is going.
Disrupt AI Summit, Ioannina: 27 November 2026
The second edition has six tracks, one on the Greek AI ecosystem. It is the only dated tech event we found in Epirus for this period.
December 2026
WordCamp Athens: 11–13 December 2026
The WordPress Greek Community marks ten years of WordCamp Athens with its first two-day programme. It is a cheap, friendly place for bootstrapped web and e-commerce founders to find developers and clients.
DevFest Thessaloniki: 12 December 2026
Run by GDG Cloud Thessaloniki at OK!Thess, the city's startup hub, with talks on cloud, AI and the web. A good place to meet technical co-founders.
Spring 2027
AI Hackathon Greece, Athens: 19–21 March 2027

BEYOND, Athens: 1–3 April 2027
Run by TIF-Helexpo, the company behind the Thessaloniki International Fair. Visitors can book B2B meetings before they arrive, which makes it useful for B2B startups selling AI to smaller companies.
Panathēnea, Athens: 26–28 May 2027
One of the largest international startup gatherings in Greece, with a Founders' Day and side events; the organisers expect about 10,000 attendees. The 2026 edition was at the Zappeion Hall.
Summer 2027
JCrete, Chania: 19–23 July 2027
