Frontline

The partnership is led by co-founders William McQuillan, Shay Garvey, and Brendan McDonnell. McQuillan and Garvey run the seed-stage fund, while McDonnell leads the growth-stage vehicle. Zoe Chambers was promoted to Partner in May 2024 to expand the growth platform. Decisions are made by the partnership as a group, with clear delineation between the two fund strategies.

Frontline's sourcing model is built on deep networks in both geographies. The seed team sources directly from European technical communities, university ecosystems, and angel networks in the UK, Ireland, and the Nordics. The growth team sources US-based Series B+ companies through direct relationships with US VCs and the firm's annual summit, which brings European founders together with American enterprise buyers.

Frontline operates two separate fund strategies. The seed fund (most recently Seed II, closed at €70 million in 2023) writes first checks into European pre-seed and seed-stage B2B software and AI companies. The growth fund targets US-based Series B and later enterprise companies that need European market-entry support. The two vehicles share a partnership and brand but deploy distinct capital and investment committees.

Frontline's seed fund writes initial checks between €200,000 and €2 million, targeting pre-seed and seed-stage B2B software and AI companies. The firm typically leads or co-leads rounds and reserves capital for follow-on investments. Confirmed portfolio companies include Verve, Signal AI, and FoodMarble.

Frontline was founded explicitly to bridge Europe and the US. The firm's growth-stage fund invests directly in US-based enterprise companies seeking European expansion. For its European seed portfolio, Frontline provides US go-to-market introductions through its network of US enterprise buyers, often starting before the portfolio company has any US presence.

Frontline invests in B2B software, AI and machine learning, fintech, and digital health. The firm avoids consumer-facing products, hardware, and life sciences. Its sector focus reflects the founder backgrounds — all three partners have operating experience in enterprise software and platform businesses.

Frontline invests exclusively in direct deals through its two fund strategies. The firm does not make fund-of-funds commitments, nor does it participate in secondary transactions. Its entire capital deployment is directed toward primary equity rounds in B2B software and AI companies.
