Profile

Marathon Venture Capital partners with ambitious founders to build world-class technology companies from the very first idea through scale and beyond, blending deep local roots with a global vision.

We aim to be the first true believers in tomorrow’s most impactful startups, deploying conviction capital alongside hands-on support. Each year, we back only a select group of outlier founders, embedding ourselves as active partners who roll up our sleeves to tackle challenges.

With over €170 million under management across three funds and marquee seed investments in companies like Causaly, Hack The Box, and Delian Alliance industries we demonstrate that conviction capital and operational rigor can turn ambitious visions into market-leading enterprises.
