TL;DR: The right Greek VC fund depends on stage, sector, geography, and cheque size. Marathon Venture Capital and VentureFriends are broad early-stage options; Metavallon, Uni.Fund, Genesis Ventures, Velocity.Partners, Apeiron Ventures, and Loggerhead Ventures are more specialised pre-seed and seed possibilities; Big Pi is particularly relevant for deep-tech and scale-up financing; and Phaistos is focused on 5G-related infrastructure. Greece has a compact but growing ecosystem, and the strongest approach is to build a focused shortlist rather than send the same pitch to every fund.
Greece's venture capital ecosystem
The latest Found.ation and EIT Digital report linked in this guide counted 16 VC funds actively investing in Greek startups and reported more than €555 million invested in over 90 Greek startups in 2024. Newer 2025–2026 directories list approximately 18 active or emerging vehicles, depending on whether they include newer managers, specialised funds, and co-investment structures. The most accurate description is therefore a compact and growing ecosystem of roughly 16–18 relevant funds and vehicles, not one definitive census.
That distinction matters because a fund list can combine conventional VC funds with research-commercialisation vehicles, state-backed programmes, angel co-investment funds, and growth investors. They do not have the same mandate, ownership model, decision process, or cheque size.
How founders should evaluate a Greek VC fund
Start with fit rather than fame. Compare your stage, first-cheque requirement, sector, geography, technical maturity, and the fund's willingness to lead or co-invest. A pre-seed university spinout should not approach a growth fund with a €7–20 million ticket, while a revenue-generating scale-up should not assume that a pre-seed fund can lead its next round.
The funding stages founders need to understand
Pre-seed capital is usually used to validate the problem, build the first product, recruit a founding team, or turn research into a company. Investors at this stage are often comfortable with limited revenue, but they still need evidence that the founders understand the market and can reach a meaningful next milestone. Seed capital is generally used to prove repeatable demand, build the core team, and establish an initial go-to-market motion. The label is not universal: one fund's seed round can be another fund's pre-seed, so the ticket size and decision criteria matter more than the name of the round.
Growth capital is different again. It is intended for companies with revenue, an established product, and a credible path to scale. Growth investors may lead much larger rounds, expect more formal reporting, and assess unit economics, retention, sales efficiency, and governance in greater detail. This is why a fund can be highly relevant to the Greek ecosystem but still be the wrong investor for a company that has not yet reached product-market fit.
What Greek investors typically look for
Greek VC funds often invest in companies with a clear connection to the country, but that connection can take several forms: Greek founders building abroad, a Greek R&D base, a university spinout, local market validation, or a team using the Greek talent and diaspora networks to expand internationally. Founders should state that connection clearly instead of assuming the investor will infer it from the company's address.
Sector fit is equally important. Greece has visible activity in software, fintech, digital health, agritech, maritime technology, robotics, energy, and deep tech. A fund's portfolio can reveal more than its homepage: look at the stage of its most recent investments, the geography of its current companies, and whether it repeatedly leads rounds or participates alongside another lead investor.
Leading Greek VC funds with recent capital
Marathon Venture Capital
Best fit: Greek-connected seed companies in B2B software, infrastructure, cybersecurity, AI, robotics, agritech, and defence technology.
Marathon closed its third fund at €75 million in 2025 and describes itself as a seed investor that leads rounds and supports companies through later stages. Its official site also publishes founder resources, including term-sheet and funding materials. It is a strong first conversation for a Greek-connected team with technical depth and international ambition.
Official profile: Marathon Venture Capital
Big Pi Ventures
Best fit: Deep tech and early-stage companies, plus European scale-ups seeking growth capital.
Big Pi announced the first closing of Big Pi Growth I at €130 million in June 2025, with a €200 million target and €7–20+ million lead tickets. That growth vehicle is aimed at companies with meaningful revenue and scale-up potential, not ordinary day-one startups. Its early-stage platform is more relevant to companies with defensible intellectual property in deep tech, AI, biotech, or digital health.
Official profile: Big Pi Ventures
VentureFriends
Best fit: Pre-seed and seed founders building marketplaces, fintech, proptech, SaaS, consumer, and travel businesses across Europe and MENA.
VentureFriends states that it invests at pre-seed and seed, writes first tickets of €500,000–€3 million, and has raised four funds with more than €300 million in assets under management. It is relevant for founders who need an early investor with a broad network and follow-on capacity.
Official profile: VentureFriends
Phaistos Investment Fund / 5G Ventures
Best fit: 5G, connectivity, IoT, space technology, and related infrastructure.
Phaistos is a specialised, state-backed vehicle managed by 5G Ventures. It is not a general-purpose seed fund for every Greek software startup. It becomes relevant when the product depends on 5G-enabled infrastructure or adjacent deep technology, and when co-investment or a sector-specific mandate is appropriate.
Official profile: Phaistos Investment Fund / 5G Ventures
Seed and deep-tech funds for first-time founders
For very early founders, the most realistic first conversations are usually with funds whose mandate explicitly covers pre-seed or seed and whose first cheque matches the company's financing need. The following funds are more specialised than the headline names, but may offer a better fit.
Metavallon VC
Best fit: Deep tech, B2B, AI, robotics, energy, transportation, space, and fintech.
Metavallon invests from pre-seed to seed+ and is especially relevant for technical founders with meaningful Greek R&D activity.
Official profile: Metavallon VC
Uni.Fund
Best fit: University and research spinouts.
Uni.Fund was created through the EquiFund platform and is designed for technical or academic teams that need capital and commercialisation support.
Official profile: Uni.Fund
Velocity.Partners
Best fit: Pre-seed and seed technology companies with Greek market validation and global ambition.
Velocity.Partners is relevant when a founder can show early customer evidence and a credible international path.
Official profile: Velocity.Partners
Genesis Ventures
Best fit: Very early companies seeking angel co-investment, coaching, and hands-on support.
Its reported ticket range is roughly €100,000–€400,000, making it a possible fit before a conventional seed round.
Official profile: Genesis Ventures
Apeiron Ventures
Best fit: Early-stage B2B software and companies connected to the Greek ecosystem or diaspora.
Because it is a newer manager, founders should verify its current mandate and contact channels before relying on older directories.
Official profile: Apeiron Ventures
Loggerhead Ventures
Best fit: Seed and early-stage climate, cleantech, and deep-tech startups, especially with a northern Greece connection.
Loggerhead is worth investigating for founders whose technology and environmental orientation match its mandate. Verify its current investment activity before outreach.
Official profile: Loggerhead Ventures
HDBI and the institutional capital behind Greek VC
The Hellenic Development Bank of Investments, or HDBI, is a Greek state-backed fund-of-funds institution. It generally supports VC managers and investment vehicles rather than acting like a standard seed fund that founders pitch directly. HDBI participation can indicate institutional backing, but it does not guarantee a fund's performance, investment speed, or long-term availability. Founders should still evaluate the actual VC manager, its partners, decision process, portfolio conflicts, and follow-on policy.
Official profile: HDBI
The wider Greek investment roster
The broader active roster includes Corallia Ventures, iGrow, Forthtech, TECS Capital, Evercurious, L-Stone Capital, Untethered Ventures, and Sporos Platform. These names cover research commercialisation, deep tech, climate and circular economy, and newer technology-focused strategies. Their public information is less uniform, so the article should not imply that every vehicle has the same level of current activity or the same accessibility to first-time founders.
Older lists may also mention Starttech Ventures, the Northern Greece Investment Fund, Attica Ventures, or Elikonos Capital. Treat those as leads for further research, not as proof that a fund is currently deploying into companies at your stage.
Preparing and sending a first VC approach
Start with a targeted shortlist of five to eight investors whose stage, sector, geography, and cheque size match the company. The first message should answer four questions immediately: what problem the company solves, what evidence of demand exists, how much capital is being raised, and why this particular fund is a credible partner. A warm introduction from a portfolio founder can help, but a clear direct approach is still valid when the fund publishes an open contact channel or application process.
Founders should verify the fund's current website, portfolio, investment stage, and team before sending a pitch. Fund mandates, ticket sizes, and contact channels change. This guide reduces search time; it does not replace final verification.
Bottom line
Greek venture capital is deeper than its best-known names, but it is not one homogeneous market. Marathon and VentureFriends are broad early-stage options; Metavallon, Uni.Fund, Genesis Ventures, Velocity.Partners, Apeiron, and Loggerhead are more useful when the founder's stage or sector matches their specific mandate; Big Pi is relevant for deep-tech and scale-up financing; and Phaistos is a specialist option for 5G-related businesses. The best fund is the one whose current mandate matches your company—not the one with the biggest headline fund size.
