Marathon Venture Capital

Marathon Venture Capital is a seed-stage venture capital firm based in Athens, Greece, founded in 2017. The firm focuses on early-stage technology companies, particularly those founded by Greek entrepreneurs or with Greek talent globally. Marathon's investment strategy emphasizes backing founders who are addressing complex, high-impact problems in sectors such as artificial intelligence, cybersecurity, agricultural technology, defense technology, and deep tech. The firm aims to support companies that are globally scalable and have the potential to make a significant impact in their respective industries.

In May 2025, Marathon Venture Capital closed its third fund, Marathon Fund III, with €75 million in capital commitments, surpassing its fundraising target in a single closing. This fund continues the firm's commitment to early-stage investments across Europe and beyond. Notable investments from Marathon include Augmenta, a precision agriculture technology company acquired by CNH Industrial in a $110 million deal, and Hack the Box, a cybersecurity upskilling platform. The firm's portfolio also includes companies like InAccel, a hardware acceleration startup, and Norbloc, a blockchain technology company.

Marathon's approach is characterized by a hands-on partnership with founders, providing not only capital but also strategic support to help companies scale and succeed in competitive global markets. The firm's name reflects both its Greek heritage and its long-term commitment to supporting entrepreneurs over the course of their journey. Marathon's track record demonstrates its ability to identify and nurture high-potential startups, contributing to the growth and development of Greece's technology ecosystem and beyond.
