Ireland punches way above its weight in venture—especially for "born global" startups. But the trick isn't "find Irish investors." It's find the 3–8 investors who are structurally set up to lead (or follow) your round, then run a tight process.

When preparing your pitch to Irish investors, having a professional data room is essential. Peony helps Irish startups organize investor materials with AI-powered document organization, track investor engagement with page-level analytics, and securely share sensitive financial and operational data. With transparent pricing at $40/user/month, Peony delivers enterprise-grade secure data rooms without the $5,000-20,000 per-deal costs of legacy platforms.

Below is a founder-focused shortlist of five Ireland-based investors that are actively deploying capital and widely respected in the ecosystem, plus exactly what to know before you reach out.

1) How to pick the right Irish investors (the ones most likely to say "yes")

Start with 4 filters (the fastest way to avoid dead-end outreach)

1) Stage fit (Pre-seed / Seed / Series A / Growth) Most "passes" are just stage mismatch. Build a list where 80% can actually invest at your stage.

2) Thesis fit (what they must believe to invest) If your company doesn't match their core pattern (e.g., B2B SaaS, deep tech, medtech), your odds drop hard—no matter how good the deck is.

3) Geography + expansion model Irish funds often love Ireland → UK/EU → US trajectories (or direct US expansion). If your growth path is different, address it explicitly.

4) Check size + lead behavior Ask: Do they lead rounds? Do they reserve for follow-ons? Funds that reserve can be long-term partners, not just "one and done."

A quick process that works in Ireland

  • Warm intros first, but don't over-optimize it—Irish VCs are generally accessible.
  • Run parallel conversations (5–10 investors) to create momentum.
  • Aim for one "lead candidate" + 2–4 strong followers.
  • For many Irish startups, Enterprise Ireland co-investment becomes part of the strategy (often alongside private funds). (More on this in the tips.)

2) The 5 most credible, active Irish investors to know (2025)

1) Frontline VC (Dublin) — the "transatlantic" specialist for ambitious founders

Best for: B2B software + founders planning serious US expansion (or US companies expanding into Europe). Frontline positions itself around enabling frictionless transatlantic expansion, investing via Frontline Seed (Europe) and Frontline Growth (US). (Frontline) They've backed 100+ companies across Europe and North America. (Frontline)

What founders should know

  • If your story includes US distribution, US enterprise, or cross-Atlantic scaling, Frontline's positioning makes them a natural fit. (Frontline)
  • They operate across two strategies (Seed + Growth), which can help when you need later-stage context early. (Frontline)

How to pitch them

  • Lead with your "why we win in the US" narrative (even if you're early): wedge, ICP, distribution, and why now.

2) ACT Venture Capital (Dublin) — the experienced, repeatable early-stage platform

Best for: Irish and Ireland-linked tech companies from early stage through growth, especially software and tech-enabled businesses. ACT highlights 140 companies backed and €600m raised across 6 funds. (actventure.capital) They're also plugged into institutional backing (e.g., their funds note support from the European Investment Fund). (actventure.capital)

What founders should know

  • ACT has a long-standing local reputation and tends to be a steady partner for building "real companies," not just quick hype cycles. (actventure.capital)
  • You'll usually do better if you show measured execution + credible go-to-market, not just vision.

How to pitch them

  • Bring a crisp view on unit economics (or the path to them), and show the next 18 months as a sequence of de-risking steps.

3) Atlantic Bridge (Dublin + global offices) — Ireland's flagship deep-tech & scaling investor

Best for: Deep tech, university spin-outs, and ambitious tech companies scaling internationally (often Europe ↔ US). Atlantic Bridge describes itself as a global growth equity technology investor with €1B+ AUM, investing across Europe and the US, with teams in Palo Alto, London, Dublin, Munich, Paris. (Atlantic Bridge) They also run a university spin-out strategy: University Bridge Fund II was launched to scale Irish research spin-outs, with Enterprise Ireland committing capital to it. (idaireland.com)

What founders should know

  • If you're deep tech (ML infra, advanced software, digital health, hardware-enabled, research IP), Atlantic Bridge is one of the most credible Ireland-linked names. (Atlantic Bridge)
  • They can be particularly relevant if your company is shaped by IP + technical defensibility and needs international market access. (Atlantic Bridge)

How to pitch them

  • Treat the pitch like a deep-tech memo: defensibility, why incumbents can't copy, and the commercialization plan.

4) Furthr VC (Dublin) — hands-on Seed to Series A for Irish software & medtech

Best for: Irish "born global" startups in software and medtech, especially when you want a very practical, hands-on early partner. Furthr VC states it makes Seed to Series A investments in ambitious Irish software and medtech companies and reserves for follow-ons. (furthrvc.ie) Independent reporting has also highlighted their ability to invest meaningful early checks (with examples of early-stage capacity). (siliconrepublic.com)

What founders should know

  • Furthr is often a strong fit when you want an investor who will roll up sleeves (strategy, hiring, positioning, fundraising execution). (Furthr)

How to pitch them

  • Be specific about what you need help with (distribution? regulated go-to-market? clinical pathway?). "Hands-on" investors respond well to clarity.

5) Delta Partners (Dublin) — foundation-stage specialist with decades of Irish VC history

Best for: Seed and early-stage tech businesses in Ireland, especially founders who value operational grounding early. Delta describes itself as an early-stage VC backing Ireland's "foundation stage" startups, and notes backing 120+ startups across multiple funds. (deltapartners.com) They launched a newer venture fund aimed at seed and early-stage technology businesses in Ireland, with cornerstone support including Bank of Ireland and Enterprise Ireland (targeting a €70m close). (enterprise-ireland.com)

What founders should know

  • Delta is a classic "early foundations" partner—good if you're building something that needs strong fundamentals rather than hype. (deltapartners.com)

How to pitch them

  • Show you're building the company properly: the market, the wedge, and the milestones that matter at seed.

3) 5 quick tips for pitching Irish investors (that actually move the needle)

  1. Bring your "Ireland-to-world" plan Even if you're local, show how you become global: target market, expansion sequence, and why Ireland is the right base.

  2. Make the round math stupidly clear How much you're raising, what it buys (18–24 months), and the 3 milestones that unlock the next round.

  3. Anchor on proof, not adjectives Traction, LOIs, revenue, retention, pipeline quality, clinical evidence—whatever "truth" exists in your category. Replace "huge market" with your wedge into it.

  4. Use the co-investment ecosystem Ireland has a real pattern of VC + Enterprise Ireland participation (especially in tech, spin-outs, and scaling plays). If relevant, signal you understand the process. (idaireland.com)

  5. Don't "network." Run a process. Book meetings in a tight window, create momentum, and politely update investors with fast weekly progress. The best founders look inevitable. Use a professional data room like Peony to organize materials with AI-powered organization and track investor engagement with page-level analytics.
