What senior banking leaders need to get right when buying a 4th-generation core solution – insights from our webinar with experts from Aperture, GFT and Tungsten Automation.
Most core transformations don’t fail because of technology. They fail because of how the decision is made.
Banks approach core replacement as a procurement exercise – a process of comparing features, scoring vendors, and replicating what they already have. That’s the problem.
“Banks are very, very good at trying to recreate what already exists… rather than looking at the strategic outcomes.”
Andrew Ng, Head of Payments and Embedded Finance at Tungsten Automation
At a time when every platform claims to be “cloud-native” and “API-first”, the real challenge isn’t understanding what a modern core is. It’s knowing how to choose one and what to optimize for.
This is exactly what banking industry experts unpack in our latest webinar. Watch the full session for detailed guidance or read on for the three mistakes that most often derail core selection.

Most core selection processes begin with a familiar pattern: defining requirements based on what the current system already does.
The problem is those requirements are anchored in a different generation of technology, and a different operating model.
What looks like a structured, objective process can quietly lock you into replicating the past, rather than enabling the future.
“Those lists are designed for the previous generation… so you end up asking the wrong questions.”
Simon Farmilo, Banking Partnerships Director at GFT Technologies
Stop asking: What does the platform do today?
Start asking: What do we need to be able to do in 5–10 years?
Vendor demos are persuasive, but they can also be misleading. They show what a platform can do, not how it performs under real-world conditions like scale, change, or regulatory pressure. That’s why running a proof of concept that tests these conditions is critical early in the selection process
“There’s a very, very big difference between cloud native and being built for the cloud versus putting a legacy system into the cloud.”
Lewis Ide, SVP APAC at 10x Banking
Stop asking: Does the demo show what we need?
Start asking: How will this platform perform under real conditions and over time?
Proofs of concept are often treated as a formality, something to validate that the technology “works.”
But in practice, they can reinforce the same flawed thinking that shapes the rest of the selection process.
“Most people are looking for the wrong things when they run a PoC.”
Andrew Ng, Head of Payments and Embedded Finance at Tungsten Automation
Too often, PoCs focus on replicating existing functionality rather than testing whether the platform can support future outcomes.
The real purpose of a PoC isn’t to confirm what a system can do – it’s to validate what it enables. As Andrew Ng highlights, you need to think: “What is the end goal? Not what is the technology.”
A PoC is essential, but its value depends entirely on shifting the focus from features to outcomes.
Great core banking platform PoCs focus not on features, but outcomes:
Can this support our future operating model?
Can we launch and evolve products quickly?
Does this unlock new value, or just replicate existing processes?
Stop asking: Does this PoC prove the technology works?
Start asking: Does this prove we can achieve the outcomes we actually care about?
At every stage of the process, from defining requirements to running a PoC, one question should anchor the decision:
What strategic outcome are we trying to unlock by moving to a 4th-generation core banking platform?
Because if that’s not clear:
You’ll recreate legacy instead of designing for the future
Innovation will remain slow, complex, and costly
You risk locking yourself into the wrong platform, and the wrong vendor.
Get it right, and the outcome is very different. You move to a cloud-native core banking platform that is future-ready by design – one you can evolve, innovate on, and grow with over time.
