Athens is emerging as one of Europe’s fastest-rising tech cities, ranking fourth in Dealroom’s Global Tech Ecosystem Index 2026 “Rising Stars” category. The ranking puts Athens behind only Istanbul, Kyiv and Zagreb in the Europe-wide group of fast-growing tech hubs.
Dealroom’s “Rising Stars” category focuses on growth rather than size. That means Athens is being rewarded not for being the biggest tech market in Europe, but for the speed at which its ecosystem is expanding.
Climbing the list
Athens’ move from seventh to fourth place marks a notable improvement in just one year. The cities directly behind Athens include Sofia, Prague, Vilnius, Lisbon and Warsaw, which highlights how competitive the European startup landscape has become.
How Dealroom measures it
The index covers 325 cities in 77 countries, making it one of the broadest snapshots of the global tech ecosystem. It starts with cities that had at least one unicorn by the end of 2025, then adds other fast-growing hubs that raised significant venture capital since 2020.
Cities are assessed as metropolitan ecosystems rather than strict municipal boundaries, as it captures the wider startup geography around each hub, including suburbs and nearby innovation zones.
Europe’s tech map
Dealroom groups Europe’s tech hubs into three categories: Global Champions, Density Leaders and Rising Stars. The first group includes mature giants such as London, Paris, Stockholm, Berlin and Munich, while the second rewards cities that produce exceptional innovation relative to their size.
Athens sits in the third group, where the emphasis is on speed, flexibility and upward trajectory. That places the city among the most dynamic and fastest-evolving tech markets in Europe.
Bigger picture
The global ranking still places San Francisco Bay Area at the top, followed by New York and London, with major Asian hubs also playing a big role. But the most important trend is the widening of the map.
