PRESS RELEASE
The milestone follows a strong 2025 where the company acquired an international PR agency
Dublin, Ireland – 2 March 2026 – Core Optimisation Ltd one of Ireland’s leading independent digital marketing agencies, today, announced the opening of its new Dublin office located at 23 Lower Baggot Street. The expansion aligns with the company recently becoming Tesco Ireland’s digital agency partner. Aiming to drive innovation and deliver tangible outcomes, Core Optimisation will provide Tesco Ireland with a range of services, including campaign strategy & management, digital media buying, insight and analytics, paid search & social and SEO. This marks a significant milestone for the Shannon-based company, which employs 60 people.
The new office reflects the continued national and international growth of the Core Optimisation group. In addition, the company acquired PR agency, ClearStory International, to expand its offering and provide holistic communications services. In 2026, Core Optimisation was named a Google Premier Partner for the tenth time, placing it in the top 3% of Google Ads partners in Ireland.
Headquartered in Shannon, Co. Clare, Core Optimisation was founded by Caroline Dunlea and David Brett in 2015. The new Dublin base will enhance Core’s ability to serve its rapidly expanding client portfolio of more than 80 brands, including Fáilte Ireland, Tesco, Tirlán, WaterWipes, Kilkenny Design, Aryzta, Powercut Clothing, ZAGG and Imagine Broadband. The new office in the heart of Dublin’s vibrant agency centre will provide a strategic hub for collaboration, innovation, and talent development.
At the launch, Caroline Dunlea, CEO and Co-Founder of Core Optimisation, commented: “Opening our new office at 23 Baggot Street is an important step in the evolution of Core Optimisation. It allows us to strengthen our footprint in Dublin, attract top-tier talent, and better support the growing needs of our national and international clients. With our data-driven and relationship-first approach, we are building long-term partnerships that deliver measurable impact for our clients. The new office coupled with winning an account of the size and scale of Tesco Ireland in a competitive pitch process shows just where we have evolved to as a company over the last ten years. Tesco sought an agency that consistently brings fresh, innovative ideas to the table and demonstrates the strength to challenge the status quo in an especially competitive environment and we are delighted to be the agency to deliver on that ask.”
