Daniel joined Portfolion in 2020 as an Investment Analyst and has been talking to founders ever since. As part of a small, hands-on team investing across the Eastern European venture ecosystem, he focuses on early-stage companies, working closely with founders to understand products, markets, and the data behind them. Daniel most often works with founders building in cybersecurity, developer tooling, IT infrastructure, enterprise software, and applied AI. He has a soft spot for technical founders who are their own first customers and for teams taking on complex, overlooked, or seemingly “unsexy” problems with ambition. At Portfolion, Daniel currently works closely with the teams of SEON, Deskbird, NORBr, Uvionix, Riptides, and Kodesage. He holds a Bachelor’s degree in Business from Corvinus University of Budapest and a Master’s degree in Finance from Central European University. Outside of work, he enjoys playing racket sports and basketball, hiking, cooking, and tasting the world.

Rado is based in Prague and focusing on super early-stage investments in a broad range of sectors. He gravitates to founders building at the edge of technology in areas where innovation can translate into tangible impact on people’s lives (e.g., healthtech, techbio or robotics). Before venture, Rado took a less conventional route through industrial/tech policy and banking. Swapping structured institutions for the beautiful chaos of startups felt less like a career move and more like an awakening. He describes himself as a (cautious) techno-optimist and a stubborn believer in Europe’s potential. He is particularly bullish on European talent and advocates for smarter (de)regulation and stronger integration as key enablers for turning the region into a global tech powerhouse. Rado holds a BA from King’s College London and an MSc from the London School of Economics. He is also very good at collecting degrees and then working in something only loosely related to them. Outside of work, Rado spends most of his time staying active, loves traveling and sports. He values time with family and friends above all else and finds inspiration in fine art.

During her studies, she gained experience as a broker analyst, focusing on fintech and capital markets. Later, she worked as a product manager at Amazon, Mastercard, and various startups of different scales, gaining extensive experience in building and scaling digital products as well as in enterprise AI-driven solutions. In her free time, she enjoys spending time in nature, whether climbing, camping, or hiking. She also likes unwinding with a good book or discovering new music at concerts or festivals.

Donat is Investment Analyst in the early-stage venture capital team at Portfolion, working closely with founders from day one – and often even before – of company building. He joined the firm in early 2025 after roles at Boston Consulting Group and Morgan Stanley. At BCG, Donat worked on projects analyzing CEE markets, and helped test and develop new AI tools for case use. During his studies, Donat researched what makes regional companies resilient to change, participated in the Hungarian Startup University Program, and completed an exchange semester in Frankfurt. There, he studied startup law and social innovation, and gained insight into the emerging startup scene in one of the continent’s most influential business hubs. He brings these insights into his work across the CEE region, with a particular focus on developing Hungary’s startup ecosystem. Talk with Donat in four languages about what you’re building, and if you really want to get to know him, invite him to play football, or mention rockets or helicopters.
