We are a pioneering early-stage venture capital firm, believing in ideas and investing in passion.

Frontline Ventures is Europe’s first community-focused fund, creating a platform for innovative tech entrepreneurs building capital-efficient businesses in high-growth markets.

Frontline builds long-term relationships with the world-class teams we invest in.

We are based in Dublin and London, but invest across Europe.

What we offer


We aim to be the FIRST institutional investor – we understand that getting the capital culture of how investors and entrepreneurs work together right is crucial.


A founder’s time is a limited resource and we try not to waste it. We spend time building knowledge and networks so that we can make FAST decisions.


We have a fund of sufficient size and flexibility to FOLLOW our successful investments through to scale. We also have strong relationships with the best later-stage VC funds around the world.

We offer capital, mentorship when needed, and a network of people that will assist founders in building their companies. We spend time working with companies to win reference customers, make key hires, and develop strategy for gaining commercial partners.

With our backing, founders can focus on customer discovery and development from the outset and get proof-of-performance within months, not years.

What we invest in

  • We believe that the way startup technology companies are funded has changed dramatically, driven by cloud-computing and the open source movement. This change will accelerate.
  • We invest at Seed and Series A stages. Typical seed investments will range from €100k-€750k and typical Series A will range from €1m-€2m.
  • We invest in software companies that are targeting opportunities in the following four areas - Big Data, Cloud Services, Internet, and Mobile.
  • Frontline Ventures invests across Europe and has offices in London and Dublin.


Frontline is wholly invested in community -
it lives in our investment approach, in our portfolio management, and in our partner culture.
