The companies listed are primarily technology, information, and internet firms based in Ireland, with a significant concentration in Dublin. These range from established enterprises to younger companies founded in the last decade. Cimpress, founded in 1995, specializes in mass-customization, while ESW, established in 2010, focuses on simplifying international e-commerce. Nuitée, from 2016, offers infrastructure APIs for the travel sector, and CameraMatics, also from 2016, provides vehicle safety solutions with AI.
A notable pattern among these companies is the prevalence of Dublin as a headquarters city, alongside other locations like Dundalk, Tyrrelstown, and Cork. Many of the newer companies, such as Techfynder (2019), TAMI (2016), and Siren (2014), provide digital platforms and services, indicating a strong focus on software and online solutions within the Irish tech sector.

Turn this list into pipeline
Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
