## About Frontline Ventures

VC Fund · London, United Kingdom

Wherever you are on your journey we have the fund to help you expandEXPERTS IN EXPANSION Founders see what the world misses. In fast pursuit of opportunity, you make critical decisions with little certainty. We get it, because we’ve been there. Frontline is the venture firm for globally ambitious B2B companies on both sides of the Atlantic.Frontline Seed speeds up ideas at inception across Europe. Frontline X is a growth-stage fund, for fast and frictionless US-Europe expansion.WE'VE LEARNED IT THE HARD WAY As a team of entrepreneurs, we have built many businesses, many ways. And as a venture fund, we’ve helped tens of founders and CEOs cross the pond. We’ve scaled too – with team members in Dublin, London and San Francisco. Today, our team, LPs and advisors represent senior leadership at many of the world’s most successful B2B companies (Think: Segment, Stripe, Looker, Linkedin, Airtable, Google and Workday – to name a few). Collectively, we can add value when founders need it most – at company defining moments.CAPITAL IS CHEAP Look around; the venture market is drowning in noise. Hundreds of funds and millions of blogposts – all claiming to “add value” left and right. We believe that capital is cheap, and we know that value-add is not made equal. Our focus is clear; we back challengers with global ambition, and we dedicate our time to helping them fly higher – faster. Our experience makes us knowledgeable. Our global network makes us unique. Want more detail or first-hand accounts? we are happy to introduce you to our founders.SYMBIOSIS In nature, the best things work together. We see the landscape ahead and can warn you of the risks, while you stay strong and focused on your goals. Indispensable; that’s how we see our relationship.
