Esports education and software startup Metastack has successfully raised a seed funding round led by early-stage venture capital firm Fil Rouge Capital.

The round also featured participation from angel investors representing the Digital Serbia Initiative and the Croatian Business Angels Network (CBAN). The capital injection is designated to scale the platform’s marketing operations, expand its centralised tactical content datasets, and accelerate product development for player improvement tools. Financial details were not disclosed.

Metastack operates as a unified esports workspace and learning platform designed to help players and teams organise game knowledge and discover tactical content. Positioned by its developers as an infrastructure solution akin to a “Google Workspace for competitive gaming,” the platform centralises strategic playbooks, map utilities, and performance metrics within a single interface.

The company’s founding team includes CEO Mihajlo Petrovic, a former Counter-Strike coach; CTO Miloš Nikić, a senior software engineer and former semi-professional player; and VP of Engineering Sava Vidaković. Notably, the startup is advised by Minh Le, the co-creator of the original Counter-Strike franchise.

In a LikedIn post, Metastack explained the startup’s long-term operational framework by drawing parallels to traditional athletics, stating that esports training infrastructure is currently at a stage of development reminiscent of basketball in the 1960s or 1970s.

Fil Rouge Capital added that the investment addresses a historical bottleneck in the sector, where the sophisticated growth of the global esports industry has consistently outpaced the grassroots tactical tools available to everyday players looking to improve.

The announcement of the funding round follows closely on the heels of institutional recognition for the startup within its regional tech ecosystem. Metastack secured first place at the Katapult Accelerator Demo Day as part of the Katapult 2026 cohort. The accelerator program itself operates under the strategic jurisdiction of Serbia’s Innovation Fund, drawing funding through joint investments from the Republic of Serbia’s Ministry of Science, Technological Development and Innovation, the World Bank Group, and the European Union.
