In the global race for artificial intelligence, where tech giants compete for computing power, top talent, and billions in investment, a number of Greek scientists and entrepreneurs have taken on leading roles, working on everything from advanced language models to autonomous AI systems.
Much of this work, however, unfolds abroad, at the world’s leading research institutions and tech hubs. Among the most influential figures is Demis Hassabis. Born in London to a Greek Cypriot father, he co-founded DeepMind and is one of the principal architects of modern AI. His work on AlphaFold, which predicts the three-dimensional structure of proteins, earned him the 2024 Nobel Prize in Chemistry, shared with John Jumper. In August 2026, he became chairman of Google DeepMind and chief scientist at Alphabet, deepening his focus on artificial general intelligence and its role in scientific discovery.
Thessaloniki-born Ioannis Antonoglou spent years at DeepMind, where he helped develop AlphaGo and AlphaZero, before co-founding Reflection AI with Misha Laskin in 2024. Backed by investors including NVIDIA, the company reached a $25 billion valuation in 2026. In October, it unveiled Beam, an advanced model positioned as an alternative to both the closed systems of America’s biggest AI companies and rival Chinese models, placing Reflection AI at the heart of the debate over technological sovereignty.
In generative AI, Anastasis Germanidis stands out as co-founder of Runway, a leader in AI video creation valued at $5.3 billion in 2026. Its tools turn text prompts and images into audiovisual content. Germanidis became CEO in February, and the company is now expanding into models that simulate the physical world, with potential uses in robotics, even as it remains at the center of debates over copyright and the future of creative work.

Anastasios Angelopoulos, co-founder and CEO of Arena, has taken a different path. His platform lets users compare how AI models perform, and its rankings have become a key benchmark for the major labs. In October 2026, Arena raised $200 million at a $3.1 billion valuation, a rise that underscores a pivotal question: who evaluates AI, and by what standards?
Spiros Xanthos, co-founder and CEO of Resolve AI, builds intelligent agents that detect and fix problems in complex IT systems. A funding round in April 2026 valued the company at $1.5 billion, reflecting the shift from AI that generates answers to AI that gets work done.
Nicky Goulimis, who previously co-founded Nova Credit, is now co-founder and CEO of Tunic Pay, which uses data and intelligent analytics to prevent payment fraud, proof that AI’s reach extends well beyond language models.
Greeks are also leaving their mark on AI research. MIT professor Constantinos Daskalakis, one of the field’s most prominent researchers, works at the crossroads of computation theory, game theory, economics, and machine learning, studying how multiple autonomous systems learn and interact, a question of growing importance in the age of AI agents. At Carnegie Mellon, Katerina Fragkiadaki combines machine learning, robotics, and computer vision to build systems that learn through simulation and better understand the physical world. At Caltech, former Meta researcher Georgia Gkioxari develops computer vision technologies that help machines recognize objects and grasp three-dimensional space.
Yannis Assael, a researcher associated with Google DeepMind, has applied AI to ancient inscriptions. After Ithaca, which restores and dates ancient Greek texts, came Aeneas, published in Nature in 2025, which helps historians interpret Latin inscriptions, showing how AI can support the humanities without replacing scholarly judgment.
At home, the national supercomputer Daedalus and PHAROS, Greece’s AI Factory, aim to strengthen domestic capabilities. But computing power alone is not enough. Greece will also need investment in research, stronger ties between universities and industry, and an environment where innovative companies can take root and grow.
The real question is not how many Greeks have reached the top of the global tech industry, but whether their expertise can help build a sustainable AI ecosystem in Greece itself.
