Description

Marathon Venture Capital is a leading seed-stage venture capital firm based in Athens, Greece, dedicated to supporting ambitious founders in building high-growth technology companies. Established with a clear vision to foster the burgeoning Greek tech ecosystem, Marathon VC focuses on early-stage investments, providing not only capital but also strategic guidance and operational support to its portfolio companies. The firm is recognized for its hands-on approach and its commitment to helping startups scale beyond local markets, often targeting international expansion from day one.

The firm has successfully raised and deployed two funds, demonstrating its growing influence and capacity within the European venture landscape. Its inaugural fund, Marathon Fund I, launched in 2017, closed at €27 million. Building on this success, Marathon Venture Capital announced its second fund, Marathon Fund II, in 2021, which secured €40 million in commitments. This brings their total assets under management to approximately €67 million, solidifying their position as a significant player in the region's early-stage investment scene. These funds enable Marathon to provide crucial early capital to promising startups, often being the first institutional investor.

Marathon VC typically targets initial investments ranging from €500,000 to €1.5 million, though they have the flexibility to participate in smaller seed rounds and larger Series A rounds, with significant follow-on capacity. Their investment thesis centers on disruptive technologies and scalable business models, with a particular interest in sectors such as enterprise software, fintech, and deep tech. They seek founders with strong technical backgrounds, global ambitions, and a clear vision for their product. Notable companies in their portfolio include Netdata, a real-time monitoring solution, and LearnWorlds, an online course platform, both of which have achieved significant international traction.

Marathon Venture Capital plays a pivotal role in the development of the Greek startup ecosystem, acting as a catalyst for innovation and growth. By backing promising local talent and connecting them with global networks, the firm contributes significantly to transforming Greece into a recognized hub for technological advancement.
