What is the most successful modeling agency in Ireland?

The question asks for the "most successful" modelling agency in Ireland. Success can be measured using different metrics that might not all point to the same outcome. Therefore, without additional information or clarification provided regarding what constitutes modelling agency "success", I cannot identify a single definitive "most successful" agency with certainty. There are multiple well-respected, thriving and accomplished modelling agencies with their own successes within Ireland, with potential for varying strengths in different spheres or specialties within the fashion or talent space.
