We partner with entrepreneurs starting out and established teams scaling their growth. We have raised €487m across multiple funds to support this goal. We invest for the long term. Our investments span technology sectors and investment stages ranging from seed to growth.

We look for companies with potentially cutting-edge, category-defining businesses in markets including application software, IT infrastructure, communications, Internet and mobile. We help founders create and scale businesses. We work as a small team with diverse strengths accessing a community of over 100 founders. 

The teams and companies we back scale their investor base as they scale their business execution and ambition. We work closely with them in this process. Over the past 20 years have built a broad network of US and European VC firms that share our vision and approach.

Our most recent funds are supported by the European Investment Fund, Enterprise Ireland, AIB and Ireland's Strategic Investment Fund.
