Sean Mullaney has spent his career at the intersection of payments and scale. European CIO at Stripe. CTO at the AI unicorn Algolia. Engineering leadership stints at Zalando and Google before that. So when he started interviewing founders last year about their banking frustrations, the pattern he found didn't surprise him—but it did bother him enough to do something about it.
On September 17, 2025, Mullaney's answer went public: Seapoint, a fintech startup building what it's billing as a "financial home" for European scale-ups, announced a $3 million pre-seed round. Frontline Ventures led the raise, with Tapestry VC, Andrena Ventures, Angel Invest, and Nomad Capital joining in. But perhaps more telling than the institutional backers is the roster of operator-angels who wrote checks: Claire Hughes Johnson, Stripe's former COO; Laurence Krieger, who held the COO seat at both Revolut and Tide; and Colm Long, ex-COO of Tines.
That's a lot of former chief operating officers betting on a banking platform. It suggests they've seen this movie before.
The Awkward Middle
The problem Seapoint is targeting sits in an uncomfortable gap. Neobanks work fine when you're three people in a WeWork. Traditional corporate banks are built for companies with finance teams and patience. But what about the 50-person startup that just raised a Series A and suddenly has employees across four countries, vendor invoices piling up in Gmail, and expense reports cobbled together in Slack threads?
Mullaney told The Irish Times that interviews with more than 50 European founders revealed a consistent pain point: they're juggling four to six different tools for banking, payments, expenses, and payroll. The duct tape holds, barely. But it's expensive, time-consuming, and—perhaps more importantly—makes it hard to actually see what's happening with your money.
Seapoint's pitch is consolidation. Business accounts, corporate cards, international payments, expense management, invoice ingestion (yes, directly from Gmail), and payroll, all in one interface. The platform runs on Modulr's e-money infrastructure rather than a full banking license, with customer funds safeguarded at JP Morgan and the Bank of England. The target customer is clear: venture-backed companies with 10 to 250 employees across the UK and Europe.
It's a crowded space. Revolut Business, Qonto, and Pleo are already well-entrenched. But Seapoint is betting that its AI-powered automation—automatic categorization, real-time reporting, financial visibility that doesn't require manual reconciliation—combined with what the company calls "white-glove" service via dedicated relationship managers, will give it an edge. Whether you can actually deliver white-glove service at scale when you're pre-seed is an open question. But the promise is part of the package.
Beta Mode, With Pedigree
Seapoint is currently in private beta. According to Crowdfund Insider, "dozens" of VC-backed startups are testing the product, including Kota, an employee benefits platform. The company is accepting signups across the UK and Europe, staffed by a team assembled from the alumni networks of Stripe, Tide, Wise, Wayflyer, and Nubank—the kind of talent roster that signals seriousness, or at least good connections.
The dual-entity structure is worth noting. Seapoint has incorporated in both Ireland (Seapoint Finance Limited) and the UK (Seapoint Finance UK Limited, established last December), a setup that lets it serve companies on both sides of the post-Brexit regulatory divide. It's the kind of operational detail that matters more than it sounds like it should.
With $3 million in the bank—a solid pre-seed in today's climate—the company now faces the classic challenge: turning founder credibility and investor enthusiasm into actual customer traction. Frontline Ventures, which led the round, recently closed €182 million across two funds and has a strong track record backing B2B software across Europe. That's not nothing. But the fintech graveyard is full of well-funded startups with impressive backers and compelling pitch decks.
Mullaney's background gives Seapoint credibility in a market where trust is currency. The operator-angels suggest people who've scaled fintech operations see the same problem he does. What remains to be seen is whether the dozens of beta users become hundreds, and then thousands. And whether a single platform can really replace the patchwork of tools that scale-ups have learned to live with, even if they complain about them.
For now, Seapoint has what every early-stage startup needs: a clear problem, experienced execution, and enough runway to find out if the market agrees.
