You've got a real VC stack now – seed, early growth, and even proper growth equity – plus a wave of funds explicitly built to back Greek founders in Greece and the diaspora.(fi-compass)

This guide walks you through:

1. How to pick the right Greek investor
2. Deep dives on the top 5 Greek VC funds you should know
3. Five practical tips for pitching them

You can pretty much treat this as your "who to talk to first" list.

1. How to pick the right Greek investor (and not waste 6 months)

Before we drop names, do a quick self-diagnosis:

A. Be brutally honest about your stage

Broadly, the Greek funds you care about cluster like this:

• Pre-seed / Seed / Early A

  • Marathon Venture Capital – early-stage tech, Greek founders in Greece & Europe.(Marathon Venture Capital)
  • VentureFriends – pre-seed & seed, with follow-ons into early growth.(PitchBook)
  • Metavallon VC – seed & "Seed+" tickets up to ~€1.5m, deep tech & B2B.(Metavallon VC)
  • Uni.Fund – seed/early stage, especially tech transfer & university/R&D spin-outs.(UniFund)

• Scale-up / Growth

  • Big Pi Ventures – early-stage deep tech and (from 2025) a €130m+ growth fund, "Big Pi Growth I", targeting late-stage Greek & diaspora startups.(Big Pi Ventures)

If you're pre-product with a pitch deck, you're playing in the pre-seed/seed lane. If you've got multi-million ARR and are expanding globally, you're in Series B-ish / growth territory and Big Pi Growth becomes extremely relevant.

B. Sector fit matters more than you think

Greek funds are small enough that they need real thesis discipline:

• Deep tech / B2B, AI, robotics, micro-electronics, cyber, energy, etc.:

  • Big Pi, Metavallon, Marathon are very relevant.(Antagonistikotita Newsletter)

• Marketplaces, fintech, proptech, travel, SaaS with global reach:

  • VentureFriends has a huge track record here; Marathon & Uni.Fund also active.(VC Mapping)

• University / research spin-outs & tech transfer:

  • Uni.Fund and Big Pi were literally created under EquiFund's "Innovation & Technology Transfer" windows.(fi-compass)

If your company doesn't obviously fit their mental bucket, you're starting from a weaker position.

C. Think Greece + diaspora, not Greece vs. abroad

Most of these funds explicitly say they back:

• Companies in Greece, and
• Greek or Greece-connected founders building from London / Berlin / US / elsewhere.(EIF)

If you're a Greek founder abroad, these funds are actually designed for you—don't self-exclude.

D. Check their ability to follow on

A great Greek investor for you:

• Leads or meaningfully participates in your current round, and
• Has enough firepower (and relationships) to join your next one.

Ex:

• Marathon closed Fund III at €75m in 2025, backed by EIF and HDBI, to keep backing early-stage tech across Greece & Europe.(Venture Capital Journal)
• Big Pi is now running both a deep-tech early fund and a €130m+ growth fund to cover later stages.(Big Pi Ventures)
• VentureFriends has €170m across three funds (VF1–3) and keeps backing its winners.(VC Mapping)

You don't want a "one-and-done" tourist; you want someone who can stick around.

2. Top 5 Greek Investors in 2025 (Deep Dive)

1. Marathon Venture Capital – Early-Stage Tech for Greek Founders

What it is: Marathon Venture Capital is an Athens-based early-stage VC fund "helping ambitious Greek and European founders build world-class technology companies."(Marathon Venture Capital)

In May 2025, they wrapped Marathon Venture Capital III at €75m, with significant backing from the European Investment Fund and Hellenic Development Bank of Investments – strong institutional validation.(Venture Capital Journal)

Stage & cheque sizes:

• Focus: seed and early Series A
• Typically first institutional money, with capacity to follow on in later rounds through larger fund size and multi-fund structure.(EBRD)

Sectors & thesis:

• Tech-driven companies across sectors—SaaS, infra, B2B, AI, etc.(Tracxn)
• Strong emphasis on Greek founders in Greece or abroad, and teams that can play on a European/global stage.(EIF)

What founders like about Marathon:

• Hands-on at early stage: They're not just cheque-writers; Marathon is known for being deep in strategy, hiring, and fundraising.
• Backed by serious institutions (EIF, EBRD, InnovFin/EFSI), which adds credibility in later rounds.(EIF)

Best fit if…

• You're an early-stage tech startup (seed / early A) with a Greek DNA and global ambition, and you want a fund that can help you get from first institutional round to proper Series A.

2. VentureFriends – Marketplaces, SaaS & Fintech with Greek Roots

What it is: VentureFriends is an Athens-based VC firm founded in 2016 by serial entrepreneurs Apostolos Apostolakis & George Dimopoulos.(VC Mapping)

They specialise in early-stage scalable B2C and B2B startups across Europe and MENA, with a strong track record in marketplaces, proptech, fintech, traveltech and SaaS.(VC Mapping)

They've raised three funds (VF1, VF2, VF3) totalling ~€170m AUM, and as of late 2025, have invested in ~88 companies with multiple new deals that year.(VC Mapping)

Stage & cheque sizes:

• Stage: pre-seed & seed, with follow-ons into Series A for winners.(PitchBook)
• Cheques: typically hundreds of thousands to low millions at early stage, increasing in follow-on rounds.

Sectors & thesis:

• Strong bias toward:
  • Marketplaces & platforms
  • Fintech & proptech
  • Travel & consumer services
  • SaaS / B2B(VC Mapping)

If you're building "a thing with supply/demand sides", they're likely relevant.

What founders like about VentureFriends:

• Founder-first culture: They explicitly present themselves as partners "who hustle with you".(VC Mapping)
• Real track record of companies scaling beyond Greece (e.g. InstaShop, Spotawheel, Blueground).(VC Mapping)
• Continue to support winners from seed into later rounds with their larger VF3 fund.(fundinfolks.com)

Best fit if…

• You're building a marketplace, consumer platform, or SaaS product with international potential, and you want operators-turned-VCs who really get that game.

3. Big Pi Ventures – Deep Tech + New Growth Fund for Scale-ups

What it is: Big Pi Ventures started as a deep-tech-focused Greek VC fund, originally under EquiFund's Innovation Window, with a clear focus on technology transfer, research-based projects and B2B high-tech companies.(Antagonistikotita Newsletter)

In September 2025, they announced Big Pi Growth I, the first tech growth equity fund out of Greece and Southeast Europe, with a €130m first close (target €200m).(Big Pi Ventures)

Stage & cheque sizes:

• Original fund: early-stage / Series A deep tech (often with tech transfer roots).(Antagonistikotita Newsletter)
• Big Pi Growth I: growth equity for scaling Greek & diaspora startups – late Series A/B and beyond, with substantial cheques.(Big Pi Ventures)

Sectors & thesis:

• Focus on technology & IP-heavy companies – e.g. robotics, micro-electronics, AI/ML, cybersecurity, energy, transportation, fintech, industrial software.(Antagonistikotita Newsletter)
• Strong angle on backing Greek founders globally and addressing the "brain drain / brain gain" dynamic.(Sifted)

What founders like about Big Pi:

• One of the few Greek players comfortable with hard-tech and IP-heavy businesses.(Antagonistikotita Newsletter)
• New growth fund means you can, in theory, stay with them from early to serious scale, instead of having to flip entirely to foreign growth capital.(Big Pi Ventures)

Best fit if…

• You're building deep tech or IP-driven B2B – especially if you're a research spin-out – and have real traction or are approaching growth stage.

4. Metavallon VC – Seed & Seed+ for Deep Tech and B2B

What it is: Metavallon VC is an Athens-based VC fund investing in early-stage technology startups connected to Greece.(Metavallon VC)

Under EquiFund's Innovation Window, Metavallon emerged as a core seed / Seed+ investor for tech ventures.(fi-compass)

Stage & cheque sizes:

• Stage: Seed and Seed+
• Check sizes: ~€0.5–1.5m per initial investment, according to their own and third-party profiles.(Metavallon VC)

Sectors & thesis:

• Strong focus on deep tech with B2B models – AI, industrial tech, logistics, energy, agri, manufacturing, etc.(OpenVC)
• Portfolio includes ventures like Think Silicon, Better Origin, Ferryhopper, Krotos, Wikifarmer, etc., which gives a good sense of the range.(OpenVC)

What founders like about Metavallon:

• Decent track record of backing companies with global potential and helping them get to their next rounds.

Best fit if…

5. Uni.Fund – Tech Transfer & University-Powered Startups

What it is: Uni.Fund is an Athens-based VC created under EquiFund, focusing on Innovation & Technology Transfer – essentially, turning university, R&D and tech space into real companies.(UniFund)

Their mission is to "unlock the hidden potential that exists in the Universities, R&D and Tech Space," helping teams develop go-to-market strategies and strong company foundations.(UniFund)

Stage & cheque sizes:

• Stage: seed / early-stage
• Cheques: early seed (e.g. €150k+ in deep-tech university start-ups like Nanoplasmas), with capacity for follow-on as ventures mature.(Nanoplasmas)

Sectors & thesis:

• Sector-agnostic, but with a clear emphasis on:
  • University spin-outs
  • R&D-heavy technologies
  • Deep tech / advanced engineering / science-based ventures(UniFund)

What founders like about Uni.Fund:

• They genuinely understand academic environments and tech transfer – IP issues, university processes, etc.
• Good partners for combining grant / EU funding with early equity.

Best fit if…

• You're spinning out of a Greek (or European) university / research institute, or your project is highly R&D-driven and at the edge of deep tech.

3. Five Quick Tips for Pitching Greek VCs in 2025

1. Lead with traction and ambition, not "Greek startup" vibes

You absolutely can play the "Greek success story" angle, but:

• Start with numbers: revenue, growth, retention, pilots, usage.
• THEN show how being in / from Greece or the Greek diaspora is an advantage: talent, cost, networks, grants.

They're trying to back global winners that happen to be Greek, not the other way around.

2. Map your story to each fund's thesis

Don't send a generic email that could apply to any VC in the world.

• With Marathon: emphasise early-stage tech, Greek/European angle, and path to a strong Series A.
• With VentureFriends: lean into marketplace/SaaS metrics and your expansion plan across Europe / MENA.
• With Big Pi: go deep on tech/IP, research roots, and scale-up opportunity.
• With Metavallon: highlight deep-tech B2B positioning and initial commercial traction.
• With Uni.Fund: stress your university/R&D roots and the path from lab to market.

Make it obvious you chose them on purpose.

3. Use the Greek ecosystem to get warm intros

Your unfair advantage:

• Greek tech is still small enough that everybody's 1–2 steps away.
• Use alumni of EquiFund-backed funds, founders in their portfolio, or local accelerators/incubators to intro you.

"Hey, we're raising X, here's a one-pager – do you think this is relevant for [fund]?" is often enough to open the right door.

4. Be transparent about round size, valuation, and use of funds

These funds are professional but pragmatic. Make life easy:

• "We're raising €3m seed / €8m Series A at €Y pre-money."
• "This gives us 18–24 months runway to reach [revenue, product, market] milestones."
• Show clearly how the round gets you to a meaningful next step (Series A/B, profitability, etc.).

Clarity = credibility.

5. Think "Greece + international", not "Greece vs international"

The best cap tables you'll see:

• Greek lead or co-lead, plus
• international co-investors (Berlin, London, Paris, US sector funds).

These Greek investors are used to co-leading with European and US VCs; they actually like it. Tell them:

• Who else you're speaking to (at least category, if not names).
• Why having both local + global investors makes strategic sense for you.

Why professional data rooms matter for Greek startup fundraising

Greek startups need to present complex documentation—financial projections, regulatory compliance, partnership agreements, and market expansion plans—professionally to build investor confidence.

Conclusion

Raising capital in Greece in 2025 requires matching your stage, sector, and geography to the right investors. The funds on this list are actively deploying, but they're selective. Bring clear traction, a Greece-as-advantage narrative, and a disciplined process—not just vision.

Having a professional data room is table stakes for serious fundraising. Peony helps Greek startups organize investor materials, track engagement, and securely share sensitive data at a fraction of legacy platform costs.

FAQ

I am a SaaS founder based in Athens raising a seed round — which Greek VCs should I target first?

For an Athens-based SaaS founder at seed stage, your top targets are Marathon Venture Capital, VentureFriends, and Metavallon VC. Marathon closed Fund III at 75 million euros in 2025 and focuses on seed and early Series A for Greek tech founders. VentureFriends has 170 million euros across three funds and specializes in marketplaces, fintech, and SaaS with pre-seed and seed cheques. Metavallon VC writes Seed and Seed-plus tickets up to 1.5 million euros with a B2B and deep tech lean. Start with whichever fund best matches your sub-sector, then layer in the others as your round fills. Peony Business at $40/admin/month gives you page-level analytics so you can see exactly which sections of your deck each VC partner reviewed and for how long, unlike Google Drive which shows zero engagement data.

What check sizes do Greek VCs typically write at seed and Series A?

Greek VC check sizes vary by fund and stage. Marathon Venture Capital leads seed and early Series A rounds from a 75 million euro fund, typically writing first institutional cheques with follow-on capacity. VentureFriends writes pre-seed and seed cheques in the hundreds of thousands to low millions of euros range, with follow-ons into Series A from their 170 million euro AUM. Metavallon VC writes Seed-plus tickets up to 1.5 million euros. For growth-stage rounds, Big Pi Ventures now has a 130 million euro-plus growth fund alongside their early-stage vehicle. Uni.Fund covers seed and early stage, particularly for university spin-outs. For a 4-person fintech team in Athens raising EUR 2M seed, you might structure Marathon as your lead at EUR 1M with Metavallon writing a EUR 500K co-invest and VentureFriends filling the remaining EUR 500K. Peony Business at $40/admin/month lets you create personalized sharing links for each fund so you can track engagement separately and prioritize follow-ups with the most active reviewers, unlike Google Drive where all three funds see the same link with zero per-viewer analytics.

I am a Greek diaspora founder building from London — can I still raise from Greek VCs or am I excluded?

You are not excluded at all. Most Greek funds explicitly back Greek or Greece-connected founders building from London, Berlin, the US, or elsewhere. Marathon Venture Capital states it helps ambitious Greek and European founders and received EIF backing specifically to cover Greece and the diaspora. VentureFriends backs early-stage startups across Europe and MENA with Greek roots. Big Pi Growth I was designed for late-stage Greek and diaspora startups scaling globally. For a solo founder building a proptech SaaS from London and raising EUR 1.5M pre-seed, VentureFriends is your strongest first target given their marketplace and proptech thesis, with Marathon as a strong co-lead if you can show a Greek engineering team or Athens-based pilot customers. Share your fundraising materials securely with Peony Business at $40/admin/month, which includes NDA gates that require investor signatures before any document is visible, compared to DocSend which lacks built-in NDA workflows.

What do Greek investors look for in a founder's data room before committing to a seed deal?

Greek VCs at seed stage look for a tight data room that proves three things: a defensible wedge with early traction, a clear plan to win outside Greece in EU or US markets, and evidence that your team can execute. Your data room should include financial projections, a cap table, product demos or screenshots, early customer evidence like LOIs or pilot data, and a clean market sizing analysis. Greek funds are small and thesis-driven so your materials need to show sector fit immediately. Peony Business at $40/admin/month uses AI auto-indexing to organize all your fundraising documents into a professional folder structure in under 3 minutes, while legacy platforms like Datasite take weeks and charge $5,000 to $20,000 per deal.

I am raising pre-seed in Greece and want to share my pitch deck securely — how do I avoid leaks to competitors?

At pre-seed, your pitch deck often contains your core insight and wedge strategy, so leaks can be genuinely damaging. For a 3-person team raising EUR 800K pre-seed from Metavallon VC and VentureFriends, your deck likely details your proprietary algorithm or market wedge that a larger competitor could replicate if leaked. Use a data room with real security controls rather than emailing PDFs or using basic file sharing. Peony Business at $40/admin/month includes dynamic watermarks that embed each viewer's identity into every rendered frame, screenshot protection that blocks and logs unauthorized capture attempts, link expiry so access automatically revokes after your fundraise closes, and instant access revocation if you need to cut someone off immediately. Compare that to Google Drive where anyone with the link can screenshot, forward, or download without any audit trail.

What is the typical fundraising timeline for a Greek startup raising seed from local VCs?

Greek seed rounds typically close in 2 to 4 months from first meeting to wire, though this varies by fund. Marathon Venture Capital, Metavallon VC, and VentureFriends all run relatively lean processes compared to larger European funds. The same principle applies in Greece: 10 hyper-targeted introductions convert better than 100 cold emails. For a 5-person B2B SaaS team raising EUR 1.5M seed with Marathon as lead, expect roughly 10 weeks from first partner meeting to wire, with 2 to 3 partner meetings and a technical deep dive before the term sheet lands. The smaller ecosystem means word travels fast, so your materials and pitch need to be polished from day one. Peony Business at $40/admin/month lets you set up your entire data room in under 5 minutes with AI-powered organization, so you are always ready when a Greek VC asks for materials, unlike legacy platforms that take weeks to configure.

Are there Greek investors focused specifically on deep tech, AI, or university spin-outs?

Yes, several Greek funds have explicit deep tech and research mandates. Metavallon VC focuses on seed and Seed-plus for deep tech and B2B startups with tickets up to 1.5 million euros. Big Pi Ventures invests in early-stage deep tech including AI, robotics, micro-electronics, cyber, and energy, and was created under the EquiFund Innovation and Technology Transfer window. Uni.Fund was specifically built for seed and early-stage tech transfer and university or R&D spin-outs, also under EquiFund. If your startup originated from a Greek university lab or research center, Uni.Fund and Big Pi should be at the top of your list. Peony Business at $40/admin/month includes AI-powered Q&A that lets investors ask questions against your uploaded research papers and technical documents and get cited answers with exact page numbers, which is critical for deep tech due diligence.

What is the best data room for a Greek founder fundraising from Marathon, VentureFriends, or Big Pi?

Your data room needs to handle the multi-fund, multi-stage dynamics of Greek fundraising where you may be talking to Marathon at seed, VentureFriends at pre-seed, and Big Pi for growth simultaneously. Peony Business at $40/admin/month gives you personalized sharing links for each fund so you can track which partner at which firm is reviewing which documents and for how long. AI auto-indexing organizes your financials, product materials, and regulatory documents into a professional structure in under 3 minutes. Built-in e-signatures handle NDAs so investors can sign and access materials in one workflow. Dynamic watermarks and screenshot protection ensure your sensitive financial data stays secure throughout the process. Legacy platforms charge $5,000 to $20,000 per deal for similar features, and DocSend limits you to basic link tracking without NDA gates or watermarking.
