EP1018: The Gen Z and Gen Alpha battleground

In this interview, Mambu CEO Fernando Zandona discusses the critical importance of securing younger customers, specifically Gen Z and Alpha, because bank loyalty often lasts a lifetime. These demographics demand fast, digitally native experiences that traditional institutions struggle to provide using outdated legacy systems. To remain competitive against agile neobanks, Zandona suggests that established firms adopt cloud-based, composable banking platforms to launch modern services quickly without disrupting their main infrastructure. This strategy, exemplified by ABN Amro, allows banks to maintain compliance and trust while innovating through a "sidecar" core approach. Ultimately, the source highlights how technology partnerships enable financial institutions to meet the evolving expectations of a savvy new generation.

SPEAKER_02 0:00

So uh I want you to think about something before we really get into it today. Did you know that in the UK, um only about 2.5% of adults actually change their primary current account each year?

SPEAKER_00 0:12

2.5%. That is, I mean, it sounds almost impossible when you first hear it.

SPEAKER_02 0:18

Right. It's completely wild.

SPEAKER_00 0:20

But it actually reveals this incredibly powerful force in the financial world, which is, well, sheer consumer inertia.

SPEAKER_02 0:28

Aaron Powell Yeah, exactly. I mean, just think about your own life for a second. Think about how often you upgrade your smartphone, you know.

SPEAKER_00 0:34

Or cycle through streaming subscription.

SPEAKER_02 0:36

Right. Or even change cars. People will change careers, they'll move to entirely different continents or like get divorced. But the institution holding their checking account.

SPEAKER_00 0:45

That is apparently forever.

SPEAKER_02 0:46

Once you pick a bank, the friction to leave is just um it's way too high for most of us.

SPEAKER_00 0:52

Which totally turns the underlying math of the banking industry into this highly skewed game. The lifetime value of a single customer becomes just astronomical.

SPEAKER_01 1:02

Absolutely.

SPEAKER_00 1:02

The data basically shows that if a financial institution can win your loyalty when you are young, say, opening your first student account, they are statistically likely to retain you for the next 40 or 50 years.

SPEAKER_02 1:13

And that reality, that 40-year commitment, is the driving force behind our deep dive today. Because if you only have one real golden opportunity to win a customer for life, then the fight for the youngest generation of customers.

SPEAKER_00 1:26

Specifically Gen Z and Gen Alpha.

SPEAKER_02 1:28

Right, Gen Z and Gen Alpha. That fight isn't just some niche side project for a bank's digital marketing team anymore. It is a high-stakes, basically uncompromising survival game.

SPEAKER_00 1:40

It really is an existential threat.

SPEAKER_02 1:42

Yeah. Because if these legacy institutions lose this specific demographic, they are staring down the barrel of total irrelevance. Trevor Burrus, Jr.

SPEAKER_00 1:49

Because they are competing against purely digital, highly agile neo banks that are being built entirely from scratch to capture this exact demographic. Trevor Burrus, Jr.

SPEAKER_02 1:58

And we actually have some incredible insights into how this boardroom panic is playing out behind closed doors. We've been analyzing a very candid interview from IBS Intelligence with Fernando Sandona.

SPEAKER_00 2:08

Trevor Burrus, he's the CEO of Mambu.

SPEAKER_02 2:10

Exactly. And to widen the lens a bit, we've also been looking at the global strategy of a universal core banking system called ICBS.

SPEAKER_00 2:21

Aaron Ross Powell Both of these sources give us this rare look under the hood. We get to see how the oldest, most traditional players in the financial sector are desperately trying to rewrite their own DNA.

SPEAKER_02 2:31

Aaron Powell Okay, let's unpack this because we are going to figure out exactly how slow massive legacy banks, you know, the institutions that built their reputations on century-old marble pillars and giant steel vaults. Trevor Burrus, Jr.

SPEAKER_00 2:46

Right. The traditional heavyweights.

SPEAKER_02 2:47

Exactly. How they are desperately attempting to reinvent themselves to win over a generation that practically lives inside their smartphones, and they have to do it all before the neo banks render those traditional institutions extinct.

SPEAKER_00 3:00

Well, to fully grasp the scale of the challenge here, we have to look really closely at the profile of the customer they are trying to acquire.

SPEAKER_02 3:07

Right.

SPEAKER_00 3:08

We're talking about a demographic that brings an entirely new set of expectations to the table.

SPEAKER_02 3:12

Zandona details this beautifully in the interview, actually. When we look at Gen Z and Gen Alpha, we are talking about demographics that didn't just learn to be digitally literate later in life. They were, as he puts it, born on the internet.

SPEAKER_00 3:26

Born on the internet. That's a great way to phrase it.

SPEAKER_02 3:28

Yeah, they were born straight into the seamless ecosystems of Apple, Google, TikTok, Uber, all of it.

SPEAKER_00 3:36

So they have zero memory of a world before instant digital gratification. Which means their tolerance for friction is like basically non-existent.

SPEAKER_02 3:47

Imagine handing a teenager a rotary phone and asking them to send a text message.

SPEAKER_00 3:51

Oh man, they wouldn't even know where to start.

SPEAKER_02 3:53

Right. But that is exactly what it feels like for a digital native to interact with the clunky, multi-step, slow-loading interface of a traditional bank's legacy app.

SPEAKER_00 4:02

It's just entirely foreign to them.

SPEAKER_02 4:04

They expect their banking to feel exactly like their favorite social media feed. Instantaneous, intuitive, and highly responsive.

SPEAKER_00 4:11

If a banking app takes like three seconds to load a balance, or heaven forbid, requires visiting a physical branch to sign a piece of paper.

SPEAKER_02 4:18

Oh, forget about it. They won't just complain. They will delete the app and move to a competitor in under a minute.

SPEAKER_00 4:25

And Zandona brings up an even more radical shift in consumer behavior here. The sources highlight that in many cases, these younger demographics don't even want to see the bank.

SPEAKER_01 4:36

Wait, really? Not even see it.

SPEAKER_00 4:39

Yeah, that concept completely reframes the whole industry. They don't want a relationship with a big institutional building on a street corner.

SPEAKER_02 4:46

That is wild. But I guess it makes sense.

SPEAKER_00 4:49

What's fascinating here is how this shifts the whole paradigm of trust. The traditional 20 to 30-year-old banking business model relied on visible presence as a proxy for trust.

SPEAKER_02 4:59

Like you trusted the bank because you could literally see the marble columns and the big vault.

SPEAKER_00 5:04

Exactly. But Xandona points out that younger users are looking for a completely different value proposition. They deeply value their own digital communities. They value extreme transparency regarding how their data is used.

SPEAKER_01 5:17

Oh, that makes a lot of sense.

SPEAKER_00 5:19

And they're paying very close attention to the ethical stances and the actual real-world values of the institutions holding their money.

SPEAKER_02 5:25

And neo banks are just natively built to provide those exact functionalities right from day one.

SPEAKER_00 5:31

Precisely. They launch with transparency reports, they integrate with community causes, and they embed their services so seamlessly into the user's phone that the bank practically disappears into the background of their daily life.

SPEAKER_02 5:44

So if a traditional financial institution attempts to operate the way it did in, say, 1995.

SPEAKER_00 5:50

Expecting customers to adapt to their processes rather than adapting the process to the customer.

SPEAKER_02 5:54

Yeah, they will completely fail to capture this demographic. The purely digital neobanks are currently flooding the market and capitalizing on this exact vulnerability.

SPEAKER_00 6:04

But this brings up a massive logistical problem for the older guys.

SPEAKER_02 6:07

Right. Because if neo banks have this incredible technological upper hand and they already speak the native digital language of Gen Alpha, how does an incumbent bank possibly fight back?

SPEAKER_00 6:18

It's not easy, that's for sure.

SPEAKER_02 6:19

They have decades of foundational infrastructure. You can't just, you know, slap a trendy user interface on top of a mainframe from the 1980s and expect it to work like a modern app.

SPEAKER_00 6:28

You've hit on the multimillion dollar bottleneck right there. The infrastructure of a traditional legacy bank is almost unimaginably complex.

SPEAKER_02 6:36

I can only imagine.

SPEAKER_00 6:38

It is this massive web of heavily regulated, highly patched systems. Many of these banks have grown through decades of mergers and acquisitions, resulting in a Frankenstein's monster of legacy code.

SPEAKER_02 6:51

What developers often call spaghetti code, right?

SPEAKER_00 6:53

Exactly, spaghetti code.

SPEAKER_02 6:55

So if you pull one string over here to launch a new feature, you might accidentally break the entire mortgage processing system over there.

SPEAKER_00 7:01

Exactly the issue. If a traditional bank relies on that core legacy infrastructure, launching a single new financial product, say a micro investing tool or a peer-to-peer payment feature can take years.

SPEAKER_02 7:14

Just for one feature.

SPEAKER_00 7:16

Years of development, endless testing, and massive compliance checks, just to ensure it doesn't destabilize the whole ecosystem.

SPEAKER_02 7:23

And in the current tech landscape, a three-year development cycle is basically a death sentence.

SPEAKER_00 7:27

Oh, without a doubt.

SPEAKER_02 7:28

By the time that legacy bank finally rolls out their new feature for Gen Alpha, Gen Alpha has already adopted like three new platforms. You just cannot compete with a neo bank pushing weekly software updates if your internal timeline is measured in years.

SPEAKER_00 7:43

Which brings us to the strategic workaround outlined in our sources. The interview provides a really compelling real-world case study of a massive institution, bypassing this exact bottleneck.

SPEAKER_02 7:55

Oh, right. ABN AMRO in the Netherlands.

SPEAKER_00 7:58

Exactly. They recognized the demographic cliff they were facing. They needed to capture Gen Z and Gen Alpha, and they knew their internal legacy systems were just way too slow to build the digitally savvy experience required.

SPEAKER_02 8:10

So instead of trying to rebuild their own engine from scratch, which would take forever, they launched an entirely new project called BU UT. That's B U U T.

SPEAKER_00 8:18

And they partnered with Mambu to build it.

SPEAKER_02 8:20

Right. And Mambu operates as a core banking provider, but their underlying architecture is entirely different from legacy systems.

SPEAKER_00 8:27

Yeah, they provide what the industry calls cloud native API-based composable core banking.

SPEAKER_02 8:32

Okay, let's break down the mechanics of that because composable core sounds like intense tech jargon, but it's really the secret weapon that makes this whole transformation possible.

SPEAKER_00 8:42

It helps to think of legacy banking software like a giant sculpture carved out of a single massive block of marble. It's solid, it's secure, but if you want to change its shape, it takes an enormous amount of time, effort, and risk.

SPEAKER_02 8:57

Right. You can't easily modify a marble block.

SPEAKER_00 9:00

Aaron Powell But a composable core, on the other hand, is like a box of digital Lego bricks.

SPEAKER_02 9:04

Oh, I love that analogy. So a bank can just pick and choose the exact financial functions they need, like a payment gateway here, a lending module there.

SPEAKER_00 9:12

Exactly. And they just snap them together using pre-built API integrations.

SPEAKER_02 9:16

That is so much more flexible.

SPEAKER_00 9:18

Yes. And crucially, Zandona emphasizes that Mambu operates on a single code base. In the old days, banks bought custom software, meaning their internal IT teams had to maintain their own unique localized version of the code.

SPEAKER_02 9:30

So if a new security regulation came out, they had to custom write the update themselves.

SPEAKER_00 9:35

Right. But with a single code base, when Mambu pushes an update or a new feature, every single bank on their platform globally gets the upgrade instantly.

SPEAKER_02 9:45

That's huge.

SPEAKER_00 9:46

It completely removes the burden of IT maintenance from the bank, allowing them to focus purely on the customer experience.

SPEAKER_02 9:52

And the timeline on the ABN AMRO project really proves the power of those Lego bricks. Because of this plug-and-play architecture, they went from concept to launching BUUT, a fully functional, modern financial experience, in just 12 months.

SPEAKER_00 10:07

12 months. In the traditional banking world, deploying a new core in a year is basically moving at light speed.

SPEAKER_02 10:14

It allows a century-old institution to match the deployment speed of a Silicon Valley startup. But um, I actually want to push back on the branding strategy here for a second.

SPEAKER_01 10:23

Okay, so let's hear it.

SPEAKER_02 10:24

Let's look at it from the perspective of a Gen Z consumer. You have a massive established incumbent bank like ABN AMRO. Instead of upgrading their main app to make it better, they quietly launch a side project under a totally new, trendy name, B U U T. Doesn't that risk feeling incredibly inauthentic? It feels a bit like, you know, a corporate executive putting on a backward baseball cap and saying, How do you do, fellow kids?

SPEAKER_00 10:49

That's a fair point.

SPEAKER_02 10:50

Like they are implicitly admitting their main brand is too slow and uncool to win over young people, so they have to invent a proxy brand to basically trick them.

SPEAKER_00 10:59

It's very valid critique. And it touches on the psychological risk of these spin-offs. But Zandona actually addresses this dynamic directly. He argues that creating a separate entity isn't an admission of failure.

SPEAKER_02 11:13

It's not.

SPEAKER_00 11:13

No, rather it's a highly calculated method of risk mitigation. He refers to this approach as a sidecar core strategy.

SPEAKER_02 11:21

Oh, I love that metaphor. Like attaching a sidecar to a motorcycle.

SPEAKER_00 11:24

Or, perhaps more accurately, attaching a sidecar to a massive, heavily armored truck.

SPEAKER_02 11:29

Okay. A truck makes more sense for a legacy bank.

SPEAKER_00 11:31

Aaron Powell Right. The traditional bank's legacy infrastructure is that armored truck. It might be lumbering and slow, but it provides incredible scale, unshakable consumer trust, and bulletproof regulatory compliance.

SPEAKER_01 11:43

You definitely don't want to try and make an armored truck drift around a corner like a sports car.

SPEAKER_00 11:48

Aaron Powell Because if you flip it, you crash the entire bank.

SPEAKER_02 11:50

Yeah, that would be disastrous.

SPEAKER_00 11:52

Exactly. You don't rip the engine out of an airplane while it's in mid-flight. Instead, the bank attaches a sleek, incredibly fast sidecar, the Mambu Cloud Core. And they run this new nimble infrastructure right alongside their massive legacy systems.

SPEAKER_02 12:08

Aaron Powell Okay, that actually makes a lot of sense. They insulate their core operations from the volatility of tech experimentation.

SPEAKER_00 12:15

Precisely.

SPEAKER_02 12:15

So if the new BUT app has a bug or needs to pivot its interface entirely, they can do that rapidly in the sidecar without risking a catastrophic failure in the main bank's mortgage or payroll processing systems.

SPEAKER_00 12:29

Aaron Powell It gives them the best of both worlds. Zandona points out that this sidecar method acknowledges the reality of the market. Traditional banks absolutely must move faster to survive, but they cannot afford to throw out a century of core compliance and trust to do it.

SPEAKER_02 12:43

And if you want proof that this isn't just like some localized European experiment with ABN AMRO, you just have to look at the global marketing landscape right now.

SPEAKER_00 12:53

Oh, it's everywhere.

SPEAKER_02 12:54

We see this technological arms race happening worldwide. The promotional materials we reviewed for ICBS, that's the Universal Core Banking and Financial Solutions provider, they illustrate this perfectly.

SPEAKER_00 13:05

They really do. They market themselves globally as a partner for this exact type of successful transformation.

SPEAKER_02 13:12

You see a massive scramble to digitize financial infrastructure extending far beyond the traditional tech hubs. I mean, just look at the hubs ICBS lists in their materials. Dubai, Malta, Beirut, Paris, Iraq.

SPEAKER_00 13:26

It's truly global.

SPEAKER_02 13:27

This isn't just a Silicon Valley trend. The realization that legacy systems are a bottleneck is a worldwide phenomenon. And the way these companies are marketing their solutions tells us a lot about where the entire industry is heading.

SPEAKER_00 13:38

Visual language they use is incredibly telling, actually.

SPEAKER_02 13:41

Oh, the marketing imagery is wild. If you look at older banking advertisements, it was all about physical presence and human connection, right? Smiling tellers, shaking hands, a family standing in front of a brick and mortar branch, heavy steel vault doors conveying security.

SPEAKER_00 13:58

Very tangible stuff.

SPEAKER_02 13:59

But if you look at the ICBS materials, the human element is almost entirely removed from the transaction. You see people wearing full VR headsets, looking out over these glowing, hypercomplex digital cityscapes.

SPEAKER_00 14:12

It looks like something out of a sci-fi movie.

SPEAKER_02 14:14

Exactly. The visuals are full of intricate, swirling blue structural patterns. It looks like a cyberpunk movie, not a bank.

SPEAKER_00 14:22

Well, if we connect this to the bigger picture, it speaks directly to a concept we could call architectural erasure. The fundamental concept of what a bank is is undergoing a profound visual shift.

SPEAKER_02 14:33

Right. The marble columns and the physical vaults are basically turning into invisible API calls. The bank is being erased from the physical street corner and completely rebuilt inside the code of our devices.

SPEAKER_00 14:44

The neon data blocks and VR headsets in those marketing materials aren't just flashy graphics designed to look futuristic. They represent the ultimate strategic goal for these institutions.

SPEAKER_01 14:55

Which is what? Exactly.

SPEAKER_00 14:56

The partnership these core providers are offering to legacy banks is not just about upgrading their internal software. It is about innovating on behalf of the customer to build an immersive digital reality where financial transactions happen flawlessly and largely invisibly in the background.

SPEAKER_02 15:14

It's essentially about building the financial plumbing for the metaverse or, you know, whatever the next iteration of the internet becomes.

SPEAKER_00 15:21

Exactly.

SPEAKER_02 15:21

The user just turns on the faucet, totally frictionless, and the legacy banks want to make sure they are the ones supplying the water, even if their name isn't stamped on the sink anymore.

SPEAKER_00 15:29

They want to be the ubiquitous, silent infrastructure powering the digital lives of Gen Alpha.

SPEAKER_02 15:35

So think about your own digital habits going forward. The next time you download a seamless, frictionless financial app, maybe one that promises a community-focused, values-driven way to manage your money with a slick, minimalist interface, take a much closer look at the fine print at the bottom of the screen.

SPEAKER_00 15:53

You might be surprised by what you find.

SPEAKER_02 15:54

Because behind that trendy, Gen Z-friendly exterior, you might just find a massive century-old traditional bank. They are quietly running a high-speed sidecar operation, utilizing cutting-edge cloud architecture to invisibly win your loyalty for the rest of your life. And they're doing it without you ever needing to step foot in a physical branch.

SPEAKER_00 16:15

To trace the arc of what we've uncovered today, we really began with the staggering reality of consumer inertia, that 2.5% switching rule that transforms early customer acquisition into a literal life or death metric for banks.

SPEAKER_02 16:29

A terrifying metric, honestly.

SPEAKER_00 16:30

From there we explore the immense friction of legacy systems and the existential threat posed by agile neobanks catering to the uncompromising demands of digital natives.

SPEAKER_01 16:40

And then the solution.

SPEAKER_00 16:42

Right. We unpack the ingenious sidecar workaround, the composable cloud-based cores that allow ancient institutions to suddenly move with the speed of tech startups, deploying entirely new ecosystems in a matter of months.

SPEAKER_02 16:54

It completely changes how you perceive the financial tools on your phone, doesn't it? You start to see the hidden architecture behind all that convenience.

SPEAKER_00 17:02

It does. And this evolution leaves us with a fascinating and somewhat provocative thought to ponder long after we finish today. What's up? If Gen Alpha truly desires frictionless embedded finance and actively prefers not to see the bank, will the very concept of a bank as an independent, visible, consumer-facing brand completely dissolve during their lifetime?

SPEAKER_02 17:25

Oh wow. Could tomorrow's bank simply become a faceless, invisible piece of code running quietly in the background, executing microtransactions while they play their favorite video game or scroll through a social platform?

SPEAKER_00 17:37

The infrastructure will remain, but the identity might vanish entirely.

SPEAKER_02 17:41

A future where the bank is everywhere, but completely unseen. Thank you so much for joining us on this deep dive. Stay curious, keep questioning the systems operating just below the surface of your screen, and we will catch you next time.
