Mark joined Portfolion in 2019 and today leads the firm’s early-stage venture investing alongside Daniel. He has backed companies including SEON, FLOWX.AI, Kodesage, Tiney, NORBr, Riptides, and Tresorit (acquired in 2021). A defining part of Mark’s journey has been his long-standing board role at SEON, which began when the company had just a few hundred thousand in ARR. Being close to the intense journey of scaling the company shaped his view of what exceptional looks like — and what it takes to build it. He brings that experience to partner with the most ambitious founders with Central and Eastern European roots, and be a reliable partner through key inflection points — from the earliest days through scaling to $100M+ ARR. Before Portfolion, Mark was part of BlackRock’s global fundamental fixed income portfolio management team. He holds a Master’s in Finance from Corvinus University and a CEMS Master’s in Management, including studies at Hong Kong University of Science and Technology. Outside of work, Mark loves spending time with his wife and young daughter — especially traveling together.
