Welcome back to the EUVC Podcast where we go behind the craft of building and backing venture-scale companies in Europe.Today, we’re joined by Sean Mullaney, Founder & CEO of Seapoint, and Will Prendergast, as the Founding Partner at Frontline Ventures.Seapoint has just come out of stealth with a $3M pre-seed to rebuild the fragile and fragmented financial stack that European startups (and later: mid-market companies) rely on. With a Stripe-forged team, AI-native development culture, and operators from Revolut, Tines & more on board, Seapoint wants to become the financial home for European startups.This conversation dives deep into founder pain, broken tooling, AI-native product building, engineering culture, the changing shape of startup teams, syndicate-building, and why Frontline backed Sean with high conviction.Here’s what’s covered:01:07 The Mission: “The financial home for European startups”03:32 Frontline’s conviction moment06:24 The founder pain: 5 tools, 5 accounts, zero clarity08:07 The invisible tax: fragmentation, reconciliation hell, no real-time view10:14 Why this problem is structurally important12:19 European vs US lens: why Seapoint is ahead13:18 AI-native engineering: “We rebuild the stack from processes, not accounts”15:19 AI agents allow senior engineers to ship full-stack features alone — compressing timelines that previously required 2–3× more engineers.17:19 Rethinking teams: fewer people, more senior, more generalist19:33 Productivity does NOT reduce funding needs — it increases ambition21:27 Culture: curiosity, experimentation, and founder-led technical push36:11 Syndicate design: Angels as a go-to-market weapon.40:23 From startup financial home → to powering Europe’s mid-market backbone: lending, treasury, automation, embedded finance.
