G4 Ventures
Karol Gogolak and Marilena Mylona co-direct G4 Ventures, a Cyprus firm blending VC fund commitments with Central European real assets since 2024.
G4 Ventures
G4 Ventures was established in 2024 by directors Karol Gogolak, Marilena Mylona, and Angeliki Englezou. Mylona serves as Administrative Manager, Gogolak as Partnership Manager, and Englezou holds roles at both G4 Ventures and the related entity G4 Friends 2 Limited. The firm is domiciled in Larnaca, Cyprus, with operational reach extending into Central Europe through its named business partners and co-investors. The firm deploys capital across two distinct tracks. The first is a venture capital strategy executed through direct fund commitments globally; Altss research identifies the firm's relationship with 33East, a venture capital firm with overlapping personnel, as a co-investment channel. The second track is a property portfolio concentrated in Slovakia and Hungary, with holdings that include the Podunajská Brána mixed-use development, the ECOHOUSE Kazanská residential project, and several land parcels such as Malinovo Three Waters and Paradise in Rajka. Investment Manager Miroslav Suchy, based in Slovakia, and Venture Capital Analyst Dionysis Partsinevelos, a mentor at Founder Institute Cyprus, anchor the firm's regional presence. The team's size and total deployment are not publicly disclosed. The firm maintains a professional network connection to Founder Institute Cyprus, where Partsinevelos mentors early-stage startups, and lists philanthropic relationships with several Slovak nonprofits, including DEPAUL Slovakia and Dobrý Anjel. This community footprint supplements the firm's investment activities and provides on-the-ground visibility into Central European ventures. No publicly documented fund closes or new platform launches were identified in the 24 months preceding this profile. G4 Ventures operates as a hybrid holding and venture investment vehicle led by a small partnership group. Its structural distinction lies in running an illiquid real-asset book in Slovakia and Hungary simultaneously with a global venture capital fund program, administered from a Cyprus base with Slovak and Hungarian operational partners. This pairing of direct property ownership and third-party fund commitments at a very early firm stage represents an uncommon capital-allocation architecture, one that ties the firm's venture exposure directly to a physical asset base rather than a purely financial LP portfolio.

Frequently asked questions
Who runs investment decisions at G4 Ventures?
Investment direction sits with the firm's directors: Marilena Mylona (Administrative Manager), Karol Gogolak (Partnership Manager), and Angeliki Englezou. Miroslav Suchy, based in Slovakia, operates as an Investment Manager, while Dionysis Partsinevelos contributes as a Venture Capital Analyst. Englezou's concurrent directorship at G4 Friends 2 Limited suggests related investment vehicles may share governance.
What is the relationship between G4 Ventures and 33East?
Altss research identifies 33East as a co-investor with overlapping personnel ties to G4 Ventures. This suggests a shared deal-sourcing or capital-deployment channel, though the precise legal structure of the arrangement — whether a club deal, separate managed vehicle, or shared partnership — is not detailed in any current public disclosure.
Does G4 Ventures own real estate directly?
Yes. The firm holds a portfolio of residential, mixed-use, and land assets in Slovakia and Hungary. Disclosed properties include ECOHOUSE Kazanská and the Bratislava Downtown Apartment Portfolio in Slovakia, plus the Malinovo Three Waters land parcel. A land position in Rajka, Hungary, is also part of the direct holdings.
What investment stages does G4 Ventures target?
The firm describes itself as a global venture capital fund investor, which typically implies LP commitments across seed to growth stages. Specific fund commitments are not publicly named. Dionysis Partsinevelos's mentorship role at Founder Institute Cyprus aligns the firm with pre-seed and seed-stage startup ecosystems.
Which geographies does G4 Ventures focus on?
Venture capital fund commitments are global in scope, per the firm's stated strategy. The direct real estate portfolio is concentrated in Slovakia (primarily Bratislava and Podunajské Biskupice) and Hungary (Rajka). The firm's partnership structure includes Slovak-based Miroslav Suchy, reinforcing Central Europe as the operational anchor for the real asset book.
