Partner, Frontline Ventures
Brendan O'Donnell co-leads FrontlineX, Frontline's $80M growth-stage fund dedicated to helping primarily U.S. software companies expand into Europe, giving him a distinctive specialization in transatlantic expansion. He combines his role as a partner at Frontline with ongoing angel investing, providing founders with both institutional VC and individual backer perspectives.

Partner, Frontline Ventures
William McQuillan co-founded Frontline Ventures after his career began at Lehman Brothers just three months before its collapse, an experience that shaped his approach to risk, followed by work at boutique investment bank Ondra Partners. He positions himself as a disruptive VC who focuses on being an expansion partner for B2B companies moving between Europe and the US, emphasizing hands-on support with international go-to-market strategy and building cross-Atlantic networks rather than just providing capital.
