FAQ

Frequently asked questions about Ireland

What does the OpenAI Dublin office actually do?

OpenAI's Dublin operation handles EU policy, partnerships and SME enablement under the OpenAI for Ireland programme launched with the Irish Government, Dogpatch Labs and Patch. It supports 700K+ active ChatGPT users and runs founder-facing programming. It is not a research office — model training stays in San Francisco — but it concentrates regulatory and GTM staff in Ireland.

Why does the Irish DPC matter so much for AI?

Most major US AI providers — OpenAI, Microsoft, Meta, Google — process EU user data through Irish entities, which makes the DPC their lead supervisory authority under GDPR's one-stop-shop. As AI Act enforcement layers in, Dublin becomes the venue for first-instance regulatory action on frontier model deployments across the EU.

What is Tines's actual product?

Tines builds a no-code automation and AI agent platform for security and IT operations teams. Customers wire in SIEMs, ticketing and identity tools, then orchestrate response workflows with optional agent reasoning. It raised $125M total, growing inside Ireland's deep SOC engineering and security talent pool.

Who is funding Irish AI in 2026?

Atlantic Bridge, Frontline Ventures, ACT Venture Capital, Delta Partners, Elkstone Partners and NDRC lead local seed and Series A. Enterprise Ireland and the Ireland Strategic Investment Fund add state capital. CeADAR's accelerator at UCD funnels follow-on. At growth, Sequoia, Accel, Index, Bessemer, Insight, Felicis and Coatue regularly co-invest, often after redomiciliation.
