Mind the Gap: Bringing Systems, Teams, and Ideas Together

The interop.io Client Forum in London brought together industry leaders to explore how interoperability is transforming financial workflows.

2025 Client Forum Recap – London Edition

On May 9th you may have noticed less fog and more clarity across the London fintech community. That’s because the interop.io Client Forum brought together some of the brightest minds in finance and technology to explore a deceptively simple question: what happens when everything connects?

Set against the backdrop of a city known for bridges and tunnels, the Forum echoed a familiar phrase, “mind the gap”, but gave it new meaning. Not between platforms and trains, but between siloed systems, fragmented workflows, and teams who just want to get things done.

Interop as a Strategic Advantage

As CEO Leslie Spiro and President Dan Schleifer opened the day, one thing was evident: interoperability has evolved from technical aspiration to strategic necessity.

From reimagining cross-platform experiences to embedding AI into desktop workflows, the conversations and demonstrations revealed a shift: interoperability has moved from a backend concern to a business-critical enabler.

Clients like Redburn Atlantic and Axpo Group shared how they’ve moved towards unified, context-rich environments — bridging the gap between systems, teams, and even devices.

And firms like BestX showed what’s possible when powerful analytics and execution capabilities converge in real time through interoperable infrastructure, offering traders insight the moment it matters.

AI Built for Humans

Our contribution centered on debuting AI as a natural extension of how teams already work. Our newly launched MCP Server embodies this approach, enabling AI to act within the same standards, rules, and workflows firms already trust. The result? An AI strategy grounded in trust, scalability, and user empowerment.

FDC3 as Foundation, Not Buzzword

As industry leaders from NatWest, T. Rowe Price, and FINOS discussed how FDC3 is powering real production workflows, it became clear: this isn’t about checking a standards box. It’s about unlocking shared context, accelerating integrations, and enabling smarter collaboration across firms.

FDC3 isn’t on the horizon. It’s already here — and changing the way work gets done.

1:1 Engineering

Attendees had focused sessions with our product engineers, which included deep dives into everything from browser interop to platform UI customizations. Seven of our experts were on hand to answer questions, explore ideas, and accelerate client success.

More than anything, the forum was a reminder that no one is building in isolation. The interop.io community is growing and with it, a shared commitment to openness, progress, and real-world results.
