Best Marketing Agencies in Dublin (2026)

Introduction

Dublin’s marketing agencies fall into two broad camps: media groups that plan and buy across every channel, and digital specialists built around search, paid social and data. The 10 agencies below cover both, and were chosen for recent results, 2025 and 2026 recognition, and the strength of their client rosters.

Media spend in Ireland is concentrated in a few groups. COMvergence figures reported by Marketing.ie in June 2026 put Core first, with €302 million of 2025 billings and a 29% market share, followed by WPP Media at €229 million and Omnicom Media Group at €128 million (€155 million once IPG, acquired at the end of 2025, is included). The same data values agency digital billings at €334 million, 42% of the total. Independent specialists compete hard for that digital share: Wolfgang Digital led the Irish contingent at the 2026 European Search Awards, and Core Optimisation opened a Dublin office in 2026 after winning Tesco Ireland’s digital account.

Every agency here has an active Dublin office in 2026. The list is unranked, since the right choice depends on your brief, your budget and which channels carry the most weight for you.

The best marketing agencies in Dublin

1. Wolfgang Digital

Employee-owned · Dublin 2 · wolfgangdigital.com

Wolfgang Digital was founded in 2007 and works across SEO, paid search, paid social, social creative, CRM and marketing automation, and data and analytics. The agency says it was the first Irish business to move to the John Lewis model of employee ownership. It took four golds and two silvers at the 2026 European Search Awards, including Best Large PPC Agency, and was named Best Global Large Integrated Search Agency at the 2025 Global Search Awards.

Clients include Zurich, Brown Thomas, Jameson, Intersport Elverys, Woodie’s and Bord Gáis. Recent awarded work covers GoCar’s local PPC, Horseware Ireland’s integrated campaign and Jameson’s UK SEO. It suits brands that want search and paid social run together by one team.

2. Core

Part-owned by Publicis Groupe · Dublin 2 · onecore.ie

Core describes itself as Ireland’s largest marketing communications company, and it tops the country’s media billings. It works through nine practices (creative, strategy, research, media, sponsorship, data, investment, learning and performance), and Publicis Groupe raised its stake from 16% to 49% in 2023. Core also publishes research, including its AI Connect 2026 study and a Consumer Mindset report in October 2026.

The Zenith team inside Core won gold at the 2026 Media Awards for Best Adoption of AI and Best International Campaign, both for IDA Ireland, and shared gold for SEO on Dalata at the 2025 Irish Digital Media Awards. Core suits large advertisers that want media, research and sponsorship under one roof. Starcom and Spark Foundry, listed separately below, sit within the same group.

3. Starcom

Part of Core · Dublin 2 · onecore.ie

Starcom is one of Core’s media agencies, and it ranks among Ireland’s top three individual agencies with €101 million of 2025 billings. It was the 2025 Media Agency of the Year at the Media Awards. At the 2026 awards it shared several golds, including Best Use of Sponsorship for Sky’s “Bound By Belief” and Best Use of Social Activation for Centra’s work around The Traitors Ireland.

Other named clients include Allianz Ireland, AIB, An Post and SuperValu Insurance. Much of the awarded work pairs media with sponsorship and content, so it fits brands looking for more than a channel plan.

4. Spark Foundry

Part of Core · Dublin 2 · onecore.ie

Spark Foundry is another of Core’s media agencies, and it placed in the top five Irish media agencies by 2025 billings. At the 2026 Media Awards it shared gold for Best Use of Regional Media with the Road Safety Authority’s “Cut Short”, and took bronze in the large campaign category for the Government of Ireland’s “Always Here: Breaking Through Silence”.

It also won silver for Best Use of AI on Vhi at the 2025 Irish Digital Media Awards, and handled media for the bonkers.ie campaign “Night Moves” in 2025. The public sector work makes it a useful reference for campaigns with behavioural goals.

5. Core Optimisation

Founder-led, Irish · Baggot Street · coreoptimisation.ie

Core Optimisation is a digital agency of about 60 people, founded in 2015 by Caroline Dunlea and David Brett and headquartered in Shannon. Despite the similar name, it was founded separately from the Core group above. The agency opened offices at 23 Baggot Street in 2026, after winning Tesco Ireland’s digital account in a competitive pitch.

The Tesco work covers campaign strategy, digital media buying, analytics, paid search, social and SEO. Other clients include Fáilte Ireland, Tirlán, WaterWipes and Aryzta. It won silver at the 2026 European Search Awards for WaterWipes content marketing and gold for Best Search Campaign at the 2025 Irish Digital Media Awards. The Dublin office is new, so ask which of your team will be based there.

6. Vroom Digital

Irish agency, founded 2012 · Adelaide Road · vroomdigital.ie

Vroom Digital covers SEO, Google Ads, paid social and digital PR. It won Best Small Agency at the 2025 Irish Digital Media Awards, and its site also lists the 2025 Spider Awards Grand Prix and a 2025 Global Search Award for using PR in a search campaign.

Clients include Europcar, PhoneWatch, PrepayPower, Yuno Energy and O’Briens Wine. Its case studies include UNICEF Ireland and EPIC The Irish Emigration Museum. It is a sensible option for brands that want digital PR and search planned together.

7. Granite

BGF-backed · Dublin · granite.ie

Granite is a digital agency whose services include search and marketing, data and optimisation, brand and strategy, and websites and platforms. It was named Large Agency of the Year at the Spider Awards in March 2026, and won Best in E-Commerce, Best App and Best Consumer Campaign on the same night. It has acquired Right Hat and Creative Media, and has taken a $10 million investment from BGF to support international growth.

Its site shows logos for Tesco Mobile, Dalata Hotel Group, ESB, Davy and Red Bull. Offices run from Dublin, Cork and Galway to Belfast, New York, Chicago and Dubai, so it is worth confirming where your account will sit. It suits growth programmes where the website and the marketing need to be planned together.

8. Idea

Irish agency · Dublin 2 · idea.ie

Idea works from Clarendon Mews on branding, marketing consultancy, web design, digital marketing strategy, advertising, and video and VR. It won gold for Best Brand Strategy at the 2025 Irish Digital Media Awards with Dublin Port, and Best in Storytelling at the 2026 Spider Awards.

The client list includes AIB, Savills, Vodafone and SFL, with recent featured work for EirGrid, Dublin Port and Ballymore. Property and infrastructure feature often, which is useful for clients in those sectors. It is a good fit for organisations that want brand and marketing handled by one team.

9. Matrix Internet

Irish agency, since 2000 · Dublin · matrixinternet.ie

Matrix Internet combines web design and development with digital marketing, including international SEO, paid digital, localisation, data and analytics, and export marketing. It has been trading since 2000, has a second office in Brussels, and carries a gold winner’s badge from the 2026 Digital Media Awards on its site.

Case studies include AIB Future Sparks, Lisney, MJ Flood and the Ladies Gaelic Football Association, and its logos include the European Commission and the European Environment Agency. Its export and localisation work is the main reason to look here, particularly for Irish firms selling into other markets.

10. Simply Social

Irish agency · Usher’s Quay · simplysocial.co

Simply Social is a social-first agency working across strategy, creative, paid and influencer marketing. Its paid offer is built around connecting creative and performance across the full funnel.

Clients include Marks & Spencer, Just Eat, Tesco, Three, Currys and Peroni, so its experience leans towards retail and consumer brands. Brands with heavy search needs may want a specialist partner alongside it.

What to look for in a Dublin marketing agency

Decide first whether you need a media group or a digital specialist. Core’s agencies and the other large groups bring buying scale, research and sponsorship relationships, which matter for TV, outdoor and national campaigns. Specialists such as Wolfgang Digital and Vroom Digital tend to suit advertisers whose budgets sit mainly in search and paid social. Some brands use both.

Ask how the agency is planning for changes in search. Core has written about how the EU’s Digital Markets Act is altering Google Search in Ireland, and some Dublin agencies now sell services for AI search. These are young disciplines, so ask for specific results and a clear account of how they were measured.

Check who owns the measurement. Agree the definition of success, the source of the data and the reporting rhythm before work starts, and make sure your own team keeps access to ad accounts and analytics if the relationship ends. Irish awards can help with a shortlist: the Media Awards, the Spider Awards, the Irish Digital Media Awards and the European Search Awards all reward different kinds of work.

Finally, look at how the work moves day to day. Performance programmes produce many ad variants, landing pages and reports, and each one needs sign-off, often from a client’s legal or compliance team in regulated sectors such as banking and insurance. An agency with one clear place for the latest versions and a visible record of feedback will lose less time to each round.

How Fabric helps marketing agency teams

Fabric gives a marketing agency one workspace for its files, client feedback and team knowledge, with AI search across all of it. The setup for performance agencies suits teams running many accounts at once, with briefs, creative, reports and call notes kept together for each client.

Search works by meaning across documents, images, PDFs and transcribed recordings, as well as connected apps such as Google Drive, Notion and Gmail. A strategist can find what a client said about a campaign and go straight to the page or timestamp. Campaign pipelines can run on Kanban boards, where any folder becomes a board and the cards are the files themselves.

Client feedback goes through shared links. Share a file or folder with the client as a commenter, with no sign-up needed, and they can use annotations to leave timestamped comments on video and audio, draw on a video frame or an image, or highlight a PDF. Threaded comments and @mentions keep the discussion with the file, and the team can mark each comment completed so a review round works like a checklist.

For finished reports and decks, any file or folder can be published as a web page. Published links are view-only, so they suit delivery more than review. Link analytics gives each recipient a named tracking link and shows opens, time spent and location.

On Team plans, self-writing docs can maintain a page for each client from meetings, Slack and the workspace, covering decisions, deliverables and open items. Fabric’s security includes AES-256 encryption and CASA Tier 2; whether that meets a particular client’s requirements is a question for that client’s own review.

Link analytics is included on Pro and Team plans, and self-writing docs on Team plans. See plans for teams.
