The Greek presence in Silicon Valley is no longer limited to isolated successes. In recent years, a new community of Greek scientists and entrepreneurs has found its place in the world’s most competitive tech environment and, through its work, contributes to Greece’s progress: transferring know-how, investments, experience, and an increasingly strong network. Their stories do not describe a permanent departure from the country, but a continuous movement between both sides of the Atlantic.

The Greeks who are changing technology

Anthimos Georgiadis is one of many Greeks who have taken advantage of Silicon Valley’s opportunities to turn ideas into reality—ideas that would have been difficult to develop elsewhere. He is the co-founder and CEO of Zumper, which he founded after studying at Oxford, Cambridge, and Harvard, and after working at the Boston Consulting Group. The idea came about when he realized as a student that the rental process was outdated, with people lining up outside real estate offices to secure available apartments. The service he created simplifies housing rentals: it lists available properties, analyzes market conditions in each area, and allows users to complete the process digitally. Today, Zumper serves tens of millions of users per year and has raised more than 140 million dollars from top capital funds, such as Kleiner Perkins and Goodwater Capital.

Another characteristic example is Andreas Raptopoulos. He grew up in Athens and studied Mechanical and Aerospace Engineering at the University of Patras, graduating first in his class. His passion for aerospace took him to London, to Imperial College and the Royal College of Art, where he combined technical expertise with design thinking. There he founded his first company, Future Acoustic, which developed an innovative system that converts “annoying” environmental noises (traffic, construction, offices) into music or pleasant sounds. This technology was licensed to Herman Miller (office furniture) and Sony (electronics and audio), which now integrate it into products such as office systems or headphones.

In 2011, he moved to Silicon Valley with an idea that seemed bold at the time: using small autonomous drones to transport medical supplies in areas without reliable roads. His company, Matternet, achieved the first official approval for commercial drone flights in the United States. Today, its systems are used by hospitals for rapid transport of samples, collaborate with major logistics providers such as UPS, and were used in critical missions during the pandemic.

Although based abroad, Raptopoulos did not detach from Greece. Matternet created a European subsidiary at the “Lefkippos” Technology Park, where it collaborates with a research team on wireless networks and automation. This move was supported by the Phaistos investment fund, showing that Greece can host activities of international tech companies when the right conditions exist.

Significant successes can also be found in other Greek teams active in Silicon Valley. Aisera, co-founded by Christos Tryfonas, develops artificial intelligence systems that automate processes in large enterprises. Arrikto, founded by Konstantinos Venetsanopoulos and Vangelis Koukis, creates tools for managing large volumes of data and developing machine learning systems. The funding they raised was considered among the largest ever received by a Greek startup at the time. Both companies maintain significant research and development teams in Athens.

How Greece connects with Silicon Valley

In 2022, the Consulate General of Greece in San Francisco created the “Hellenic Center Silicon Valley,” an initiative that brings together Greek tech professionals, researchers, entrepreneurs, and investors. The aim is to cultivate a network that gives Greek companies direct access to global market knowledge and trends, and allows Greeks abroad to support those starting out in Greece.

The results of this connection are measurable. In 2024, Greek startups attracted 555 million euros in investments, marking an increase during a period when other European countries saw declines. The majority of the capital that arrived in Greece came from abroad, often from companies and investors directly linked to the Greek community in Silicon Valley.

At the same time, many Greek-founded companies abroad now serve as role models. Blueground, based in New York, has gained significant value in the furnished rental market, while BETA CAE, a Greek software company, was acquired by an American group for an amount that remains the largest tech acquisition in the country. In every presentation, seminar, online course, or visit of Greek founders to Athens, the distance between the two sides grows smaller. The Greeks of Silicon Valley act as mentors, advisors, and connectors for Greek teams seeking to take the next step.

The conclusion is clear: Greece is developing its talent in an international environment, and through the ongoing relationship they maintain with the country, it benefits from the ideas and capabilities they acquire. This is a circular process of knowledge and experience exchange—essential for any modern tech ecosystem that seeks to lead in the coming years.
