Dimitrios Skaltsas
Dimitrios Skaltsas is the co-founder and CEO of Intelligencia AI, a New York enterprise software company that uses machine learning and curated biomedical data to estimate the probability that a drug candidate will win regulatory approval. Trained as a lawyer in Athens and London, he spent more than a decade at McKinsey, where he built and led New Ventures' big-data and AI work for pharmaceutical R&D before co-founding Intelligencia with Vangelis Vergetis in 2017. Under his leadership the company raised a Series A, was named one of Forbes's Top AI Companies to Watch, secured a U.S. patent for its probability-of-success assessments, and landed on the Inc. 5000. He is also an Executive in Residence at INSEAD.
Johannes Galatsanos
Johannes Galatsanos is Co-Founder and CEO of Diffraqtion, a Boston-based quantum imaging startup that has built a quantum camera capable of recovering 95% of photon information lost by conventional sensors - translating to 20x higher resolution and 1,000x faster image processing than any existing optical system. A multilingual MIT and Oxford graduate with Greek-German roots, Galatsanos pivoted from leading AI and data transformation at Novartis to commercializing a decade of DARPA- and NASA-backed quantum photonics research. Diffraqtion won first prize at SLUSH 2025, secured a $4.2M pre-seed round in January 2026, and is targeting satellite launches for space domain awareness and Earth observation by 2028-2029.
Georgios Pipelidis
Georgios Pipelidis is the co-founder and CEO of Ariadne, a Munich-born company that turns the anonymous radio signals leaking from smartphones into privacy-first analytics about how people move through airports, stores and stations - no cameras, no apps, no network connection required. A computer scientist with a PhD in artificial intelligence from the Technical University of Munich, he turned an academic project on indoor positioning - one that beat Google, IBM, Samsung, Cisco and Sony at a 2018 global competition - into a company operating sensors in hundreds of locations worldwide, backed by a $7M Series A.
Spiros Xanthos
Spiros Xanthos is the Founder and CEO of Resolve AI, the San Francisco-based agentic AI company building autonomous software reliability engineering at unicorn valuation. A serial entrepreneur who co-created OpenTelemetry, sold two companies (Log Insight to VMware, Omnition to Splunk), and went on to run Splunk's $400M+ observability business before founding Resolve AI in 2024. In under 18 months the company raised $160M, reached a $1.5B valuation, and landed customers including Coinbase, DoorDash, and Salesforce - built on the conviction that engineers spend 70% of their time keeping software running rather than building it.
Pantelis Kalogiros
Pantelis Kalogiros is a Greek-born technologist-turned-investor serving as General Partner at Cox Exponential (CX2), the early-stage AI investment vehicle of Cox Enterprises. He co-founded Fyusion in 2014, building its web infrastructure to handle 2.7 billion daily requests and embedding its 3D vision SDK into 200 million devices before the company was acquired by Cox Automotive in 2020. A self-taught dropout who obtained a U.S. green card without a bachelor's degree, Pantelis brings rare depth as both a hands-on engineer and active venture investor focused on applied AI.
