AIB: Engineering Trust Through Tech in the AI Banking Era

AIB is entering its next phase of digital banking with a clear proposition: combining trust, scale and operational discipline with a platform-led approach to innovation.

For Graham Fagan, Chief Operating Officer at AIB, the past three years have been less about isolated transformation programmes and more about resetting how the bank delivers change at scale.

“It’s been a very consequential period in terms of laying the foundations for the next decade,” he explains. 

“Culturally, it’s been about bringing the organisation on a journey around being much more digitally literate – not just AI but data and just general digital capabilities.”

That shift has been formalised through the integration of technology and operations into a single function under his leadership. 

The result is a more unified delivery model designed to accelerate execution while maintaining stability.

Graham adds: “We’ve been on a journey to create a transformation engine for the bank as it comes into its next strategic cycle.”

Building trust, resilience and performance

AIB’s strategy is anchored in its role as a systemically important financial institution, where reliability is not just expected but scrutinised.

Graham says this approach is inherently in AIB’s nature – being in the business of trust, he says that “job zero for us is security and service”.

And, with 3.4 million customers and €400m (US$455.8m) in annual technology investment, the bank is doubling down on infrastructure and cyber resilience. 

Its reported 99.99% availability across core services reflects that focus, but Graham is clear that such performance requires constant vigilance.

“You have got to fight hard for that kind of performance every day,” he asserts. “If your infrastructure is not there, you are not going to achieve that type of outcome.”

Graham frames this as a broader industry shift: “Trust is the new user experience because as much as technology has advanced, in the volatile world that we operate in, availability cannot be taken for granted.”

Enabling platform-first digital banking

Central to AIB’s next phase is the launch of a new mobile app, built on a proprietary digital engagement platform designed for continuous evolution rather than periodic upgrades.

“We have built what we call a digital engagement platform,” Graham explains, “and our new mobile app is the first service to use it.

“But really what we’re about is hopefully building it once and using it many times.”

The approach lines up with a wider move across banking towards reusable architecture and faster release cycles. 

Rather than treating the app as a standalone product, AIB is using it as a gateway into a broader ecosystem of services.

“We already have plans to add to it by the end of the year – and we couldn’t have worked in that way previously.”

Alongside features such as instant payments and enhanced navigation, AIB has placed a firm emphasis on orchestrating secure, low-friction experiences that align with customer expectations shaped outside financial services.

Having a deliberate approach to AI

While many banks have accelerated AI experimentation, AIB has taken a more controlled route – prioritising internal capability, governance and targeted deployment.

Graham says that AIB welcomed the learning curve and embraced the idea of educating themselves.

That philosophy has informed investments in a centralised AI Centre of Excellence, cloud-based data infrastructure and enterprise-wide tooling such as Microsoft Copilot. 

Crucially, the focus has been on scaling practical use cases rather than proliferating pilots.

Graham says: “We haven’t spun up loads of proofs of concept – you hear about this kind of purgatory that people end up in where they’ve started loads of pilots. 

“We’ve been very intentional about what we were doing and where we were doing it.”

Applications span fraud detection, software engineering productivity and customer engagement, including its digital assistant Abi, which has delivered strong engagement and satisfaction metrics in contact centres.

But AIB’s transformation extends beyond technology into organisational design – particularly in how it approaches risk.

“Risk is now systemic,” Graham says. “What might start off as a cyberattack could lead to an IT outage, which could then lead to fraudsters manipulating that fact.”

To address this, the bank has consolidated cyber, resilience, physical security and IT operations into a single structure, supported by shared data and tooling. 

The goal is not just faster response, but better anticipation of interconnected threats.

“No matter what the advances are in the tooling, the expertise and the human capital are more important than ever,” Graham emphasises.

Delivering change without disruption

Balancing continuous transformation with operational stability remains one of the sector’s hardest challenges. 

For AIB, success lies in aligning strategy, execution and customer impact into a single system.

“We’ve got to run with absolute excellence,” Graham says. “We’ve got to deliver a change portfolio of programmes every year that move our sustainment, regulatory and strategic objectives forward – and we’ve got to transform the way we work, our operating model, all the time.”

This is where Graham sees competitive differentiation emerging – not from any single technology, but from consistency of delivery.

And as AIB rolls out its new app and expands its AI capabilities, its approach signals a broader industry direction: platform-led, trust-centric and operationally integrated.
