Oktogon Ventures

Investment decisions are made by the partnership led by General Partners Gyula Fehér and Veronika Pistyur. Fehér is the operational anchor, having co-founded the firm after a significant CEE technology exit, while Pistyur and Principal Péter Parragh complete the three-person investment team that sources and diligences all portfolio opportunities.

The firm sources heavily through its founders' networks across Hungary, Poland, the Czech Republic, Romania, and neighboring CEE markets. Its website solicits detailed applications that probe competitive dynamics, timing rationale, and unit economics, indicating a filtered pipeline rather than spray-and-pray origination. Co-investor relationships with Western funds also generate referrals.

Oktogon operates as an asset manager running a pooled venture fund, not as a family office. Its public-facing materials reference one fund, 25 portfolio companies, and a disciplined initial check size of €100,000 to €400,000, all consistent with a conventional early-stage venture firm structure.

Oktogon almost always invests as a co-investor alongside other VCs and does not seek buyout control. It reserves up to €1.2 million per company for follow-on rounds, and its co-investor roster — which names Insight Partners, Partech, Lakestar, and Lightspeed — indicates a model that relies on larger funds to supply growth-stage capital for its seed picks.

The firm targets early-stage, revenue-generating B2B SaaS companies across technology-heavy verticals. Its portfolio spans DevOps (Bitrise), AI video (Colossyan), cybersecurity (BitNinja), electric motor hardware (Linear Labs), and sales enablement (Recart), with a consistent emphasis on CEE founders building for global markets from day one.

No philanthropic foundations, real-asset arms, or parallel vehicles are disclosed. The firm presents as a single-fund early-stage venture manager without an explicit impact or philanthropic mandate — though its portfolio includes health-tech (Genomate) and education (STEAM Academy) companies that carry social dimensions.

Oktogon does not publish its fund size, which is common among smaller, regionally focused early-stage managers that raise from a concentrated LP base. The absence of disclosed AUM means an allocator cannot independently size the vehicle, but the firm's €185 million in aggregate portfolio follow-on investment and co-investor pedigree offer an indirect proxy for its capacity to attract downstream capital.
