EP972: Winning with Essence Enabling Banks to Adapt, Evolve and Thrive
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
This interview features Siobhan Byron from Finastra explaining how their Essence core banking platform enables financial institutions to succeed in a digital-first economy. The text highlights successful partnerships with Tonik and Oro Bank, demonstrating how cloud-native architecture and modular design allow for rapid product launches and reduced operational costs. Byron emphasizes that modern banking is shifting toward open finance and embedded services, requiring systems that are both agile and highly interoperable. A significant portion of the discussion focuses on the integration of artificial intelligence, including generative AI assistants and predictive analytics, to enhance employee productivity and customer personalization. To manage the risks of modernization, the source introduces the "Symbiosis" approach, which allows banks to upgrade specific components incrementally rather than replacing entire legacy systems at once. Ultimately, the source illustrates how technological flexibility helps banks navigate regulatory complexities and meet evolving consumer expectations.
Whenever you tap your phone to pay for a coffee or you know quickly check your account balance while standing in line, you probably don't really think about the massive, invisible digital plumbing making it all happen.
SPEAKER_00Right. I mean, why would you? It just works.
SPEAKER_01Exactly. It just works. But as a learner, you're the kind of person who always wants to know about the mechanisms behind the curtain. And right now, that digital plumbing, which the financial industry calls core banking, is undergoing a radical high-speed evolution.
SPEAKER_00Aaron Powell Oh, for sure. It's a total paradigm shift.
SPEAKER_01Yeah, because we all expect our money to move instantly, securely, seamlessly. But the systems actually holding that money were, in a lot of cases, built decades ago.
SPEAKER_00Honestly, historically, those systems were built with the exact same philosophy as physical bank faults.
SPEAKER_01Like thick steel doors and all.
SPEAKER_00Metaphorically, yeah. They were designed to be impenetrable, heavy, and just extremely difficult to change or move. The priority back then was absolute lock and key security, not speed.
SPEAKER_01Which makes sense for the time.
SPEAKER_00Totally. But the demands of the modern consumer simply don't align with that kind of rigid, unyielding architecture anymore. People want their banking embedded into their daily lives, right? Not locked away in a digital fortress that takes, you know, three business days to clear a simple transfer.
SPEAKER_01Right. And that tension between old school vaults and modern expectations is the entire focus of our deep dive today.
SPEAKER_00It's such a fascinating topic.
SPEAKER_01It really is. So we are pulling from an incredibly detailed October 2025 interview from the IBSI FinTech Journal. It features Siovan Byron, who is the executive vice president of Finastry Universal Banking.
SPEAKER_00She has a lot of brilliant insights in this piece.
SPEAKER_01She really does. So the mission for us today is to explore exactly how this traditional, clunky banking infrastructure is morphing into highly adaptable, AI-driven platforms for possibility.
SPEAKER_00I love that phrase, platforms for possibility.
SPEAKER_01Me too. And by the end of this, you're going to understand what this massive technological shift means for the future of how you interact with your money. Okay, let's unpack this. If we really want to understand the theory of this new banking architecture, it probably makes the most sense to look at the actual real-world results it's producing first.
SPEAKER_00Aaron Powell, the outcomes are definitely the best entry point because you know the underlying technology can get pretty abstract very quickly, but the business results are just undeniable.
SPEAKER_01Yeah, let's ground it in reality.
SPEAKER_00Right. So the interview highlights two major success stories that were recently celebrated at the IBSI DBA Awards. And both of these institutions are utilizing Finastra's flagship core banking platform, which is called Essence.
SPEAKER_01Aaron Powell Yeah, I was looking at the numbers for the first one. So it's Tonic, a digital bank operating in Southeast Asia. And the numbers are staggering.
SPEAKER_00Oh, they really are.
SPEAKER_01It's not just a slight bump in efficiency. In just two years, Tonic managed to reduce their operational costs fivefold.
SPEAKER_00Fivefold. That is huge.
SPEAKER_01Huge. And at the exact same time, they expanded their loan portfolio sevenfold. Right. Shrinking your operating costs while simultaneously exploding your growth is well, it's essentially the holy grail of business. Absolutely. And the source explicitly links this achievement to something within the Essence platform called a no-code product composer. But what does that actually mean for the people working there? I mean, how does a piece of software bypass the usual growing pains of a bank?
SPEAKER_00Well, to understand the mechanism behind that, you really have to look at how a traditional bank launches a new product.
SPEAKER_01Aaron Powell Okay, walk me through it.
SPEAKER_00Let's say a bank wants to offer a brand new type of personal loan. Historically, the product team dreams it up, but then they have to hand it over to the IT department.
SPEAKER_01Aaron Powell The dreaded IT handoff.
SPEAKER_00Exactly. The engineers have to write thousands of lines of raw code, test it in an isolated sandbox, try to integrate it into the massive core system, and just hope it doesn't accidentally crash the mobile app.
SPEAKER_01Sounds like a nightmare.
SPEAKER_00It creates a massive bottleneck. I mean, it can take six months to a year just to launch one simple loan product.
SPEAKER_01Aaron Powell So the IT department basically becomes a traffic jam for any new business idea.
SPEAKER_00Precisely. What the no-code product composer does is remove that engineering bottleneck entirely. It provides a visual drag and drop interface.
SPEAKER_01Aaron Powell Like literally dragging and dropping on a screen.
SPEAKER_00Aaron Powell Yeah, pretty much. So the business teams, the product designers, the marketing folks, they can actually build and configure the loan product themselves using pre-built software modules. They don't need to write the underlying code because it's already been written, tested, and secured.
SPEAKER_01So it's basically like a massive set of high-tech Lego bricks.
SPEAKER_00Oh, that's a perfect way to put it.
SPEAKER_01Right. Because instead of custom manufacturing every single piece from scratch, banks can just snap together these pre-built functionalities to create an entirely new product overnight.
SPEAKER_00What's fascinating here is that success in modern banking is no longer just about financial stability or having the most capital reserves. The new competitive battleground is entirely dependent on agility and time to market.
SPEAKER_01Time to market is everything.
SPEAKER_00It really is. Because Tonic could use this visual composer to build and launch products instantly, they completely bypass the IT delays that choke their competitors. Wow. And because the Essence platform provides real-time access to core banking data, Tonic could analyze exactly what their customers were doing. They achieved deep personalization and iterated their products on the fly.
SPEAKER_01That is wild. But you know, Tonic's growth is impressive, but agility isn't just about launching new loan products faster. Sometimes it's about building an entire financial institution from literal scratch.
SPEAKER_00Which is no small feat.
SPEAKER_01Not at all. Which brings us to the second massive success story in the reading Oral Bank. This is a brand new digital bank set up to be a catalyst for Bhutan's Jellifie Mindfulness City.
SPEAKER_00Right, the new urban initiative they're building in Bhutan.
SPEAKER_01Exactly. And the interview mentions Orobank is a full reserve digital bank.
SPEAKER_00Yeah.
SPEAKER_01I want to pause right there because that changes the entire technological requirement of the bank, doesn't it?
SPEAKER_00Oh, it changes everything about their operational model.
SPEAKER_01How so?
SPEAKER_00Well, a traditional bank takes your deposits and lends them out to other people to make a profit. That's fractional reserve banking.
SPEAKER_01Aaron Powell Right, the standard model.
SPEAKER_00Yeah. But a full reserve bank doesn't do that. They keep 100% of customer deposits safely on hand. They do not lend your money out.
SPEAKER_01Aaron Ross Powell Oh, wow. So how do they make money?
SPEAKER_00Well, because they aren't making money on complex loan underwriting and interest rate spreads, their entire business model relies purely on transaction speed, service fees, and offering a totally seamless digital experience.
SPEAKER_01Aaron Powell, which means their technology stack has to be flawless from day one.
SPEAKER_00Exactly.
SPEAKER_01And according to the interview, thanks to a cloud native open architecture and APIs, Oral Bank launched globally in an incredibly fast six months.
SPEAKER_00Six months is just unreal.
SPEAKER_01Aaron Ross Powell Right. To go from zero to a fully operational global bank in half a year, that feels like breaking the sound barrier in finance.
SPEAKER_00Aaron Powell It really illustrates the absolute raw power of API first design.
SPEAKER_01Aaron Powell Let's break that down for the listener. What is an API doing here?
SPEAKER_00So an API or application programming interface is essentially a universal translator between different pieces of software. Instead of Oral Bank having to custom build their own payment gateways or their own foreign exchange calculators or specialized identity verification systems from scratch.
SPEAKER_01Which would take years.
SPEAKER_00Exactly. The API allows their core system to instantly talk to and plug into specialized FinTech partners that already do those things perfectly.
SPEAKER_01So the underlying technology is shifting away from building everything in-house. That really explains the speed.
SPEAKER_00It does.
SPEAKER_01Sebon Byron notes in the interview that core banking is no longer just about processing transactions. She actually calls it a strategic enabler of innovation.
SPEAKER_00And that is a fundamental philosophical shift in the industry. I mean, the old banking core was a ledger. It simply recorded what happened yesterday.
SPEAKER_01Just a digital notebook.
SPEAKER_00Right. But the new core is an engine. It dictates what is possible tomorrow. Because the end consumer, you, the listener, now expects instant, intuitive, digital first experiences.
SPEAKER_01Aaron Powell, we really do. We have zero patience.
SPEAKER_00Exactly. You don't tolerate friction anymore. If an app takes too long to load, you just switch banks.
SPEAKER_01Yeah, it's that easy now. And to deliver that kind of frictionless experience, Byron mentions that banks are being pushed toward microservices. Let's visualize this. The old way of building software is what they call monolithic. It feels a bit like a traditional restaurant where you have one single, incredibly stressed-out chef cooking every single item on the menu.
SPEAKER_00That sounds exhausting.
SPEAKER_01Right. And if that chef gets sick, the entire restaurant shuts down. But a microservices architecture feels more like a modern high-end commercial kitchen.
SPEAKER_00Okay, I see where you're going with this.
SPEAKER_01You have specialized independent stations. You have a grill station, a pastry station, or a prep station. They all coordinate, but they function independently. If the pastry chef is running slow, the grill is still pumping out steaks perfectly fine.
SPEAKER_00That is a perfect way to visualize it. In a banking context, instead of a tangled knot of code where the user interface, the transaction processor, and the security protocols are just permanently fused together.
SPEAKER_01Like a giant bowl of spaghetti code.
SPEAKER_00Exactly. Microservices break everything down into independent, bite-sized applications. If the customer login portal experiences a glitch, it doesn't take the core transaction engine down with it.
SPEAKER_01That's a huge relief for uptime.
SPEAKER_00Oh, massive. They communicate constantly, but they operate autonomously. And going back to your kitchen analogy, if you suddenly decide you want to offer world-class sushi, you don't have to rebuild the entire kitchen or retrain your grill cook.
SPEAKER_01You just plug a specialized sushi chef into the existing line.
SPEAKER_00Aaron Powell Right. That's exactly what microservices allow banks to do with external fintech partners.
SPEAKER_01Let me push back on something from the reading, though, because there feels like a contradiction here.
SPEAKER_00Oh, what's that?
SPEAKER_01So I'm looking at Byron's comments about the deployment of this technology. Obviously, cloud native architecture is what allowed Ourobank to scale up globally in just six months, but the interview explicitly states that on-premise deployment is still a preferred approach in many regions. Wait, if cloud technology is the ultimate key to scalability, speed and these open APIs, why on earth would a bank in 2025 still choose to install software on physical servers in their own basement? I mean, shouldn't everyone just be in the cloud by now?
SPEAKER_00It's a really great question. It seems highly counterintuitive when we just spent the last five minutes praising the speed of the cloud, but there is a bit more to it than just, you know, technological stubbornness.
SPEAKER_01So it's not just old school IT guys refusing to adapt.
SPEAKER_00No, not at all. It is actually a hard legal reality. See upon Byron makes the point that flexibility is the actual goal of modern banking, not just forcing everyone onto the cloud. Many countries have incredibly strict data sovereignty laws.
SPEAKER_01Aaron Ross Powell Meaning the government dictates where the data physically lives.
SPEAKER_00Aaron Powell Precisely. A regulatory body might legally mandate that the financial records of its citizens cannot cross national borders, or maybe the data cannot reside on cloud servers that are owned by a foreign tech giant.
SPEAKER_01Aaron Powell Oh, that makes total sense.
SPEAKER_00Right. If you are a bank operating in one of those jurisdictions, an on-premise deployment isn't a technological lag. It is a strict legal requirement to keep your banking license.
SPEAKER_01Interesting.
SPEAKER_00And what makes FNASTRA's platform a true strategic enabler is that it doesn't force the bank into a corner. It offers that exact same modular microservices architecture, whether the bank is hosting it in a public cloud or safely locked inside a highly secured on-premise data center within their own country's borders. Exactly.
SPEAKER_01But that brings up a massive operational hurdle.
SPEAKER_00Which one?
SPEAKER_01Well, we've established that this microservice architecture is incredibly powerful for new digital players like Tonic or Oro Bank. But what happens to a legacy bank?
SPEAKER_00Ah, the big guys.
SPEAKER_01Yeah. Imagine a massive institution that has been around for 80 years holding millions of mortgages, running on a mainframe that looks like a prop from a 1980s sci-fi movie. How do they survive this shift? Because they can't just pause their business for a year to rebuild their systems.
SPEAKER_00That is the existential question keeping traditional banking executives awake at night. For decades, the standard procedure for upgrading those ancient banking systems was a process the industry grimly refers to as rip and replace.
SPEAKER_01Which sounds terrifying for something that handles people's life savings.
SPEAKER_00It is a complete logistical nightmare. Siobhan Byron warns that the rip and replace method comes with prolonged timelines, astronomically high costs, and severe operational disruption.
SPEAKER_01I can't even imagine.
SPEAKER_00You are essentially turning off the life support of the bank's database late on a Friday night, trying to migrate millions of complex accounts over the weekend, and praying the new system actually boots up when the branch is open on Monday morning.
SPEAKER_01That is so risky.
SPEAKER_00It is. And if data gets corrupted during that weekend transfer, the fallout is catastrophic. People can't access their paychecks, the whole system breaks.
SPEAKER_01Here's why it gets really interesting because Finastra is advocating for a completely different methodology to avoid that exact nightmare. They call it a symbiosis approach.
SPEAKER_00Aaron Powell And this leans heavily on that microservices concept we just discussed. Instead of tearing out the old legacy system all at once, they deploy a next generation core banking system right alongside the existing infrastructure.
SPEAKER_01So they run in parallel.
SPEAKER_00They run in parallel.
SPEAKER_01It's like, okay, imagine you realize your old house has a terrible foundation and outdated plumbing, but you still have to live in it. Right. Rip and replaces bilddozing the house with all your furniture inside and trying to rebuild it before it rains.
SPEAKER_00Good luck with that.
SPEAKER_01Yeah, right. But the symbiosis approach is like building a brand new, highly advanced house around your existing house. You keep living in the old rooms, but you slowly move your furniture into the new rooms one by one. You reroute the plumbing piece by piece.
SPEAKER_00Aaron Powell Oh, that's a brilliant way to explain it.
SPEAKER_01And once you are safely living in the new structure, you just quietly dismantle the old one from the inside.
SPEAKER_00If we connect this to the bigger picture, this symbiosis approach directly mitigates the absolute biggest challenge facing the banking sector today, which is managing uncertainty and operational risk.
SPEAKER_01Aaron Powell Because bank executives are naturally risk-averse.
SPEAKER_00Inherently purposefully risk-averse. They are guarding people's livelihoods. Symbiosis allows traditional banks to foster a culture of change incrementally.
SPEAKER_01So they can test the waters.
SPEAKER_00Exactly. They can look at their operations and say, okay, our legacy mainframe is perfectly fine for handling basic checking accounts for now, but we want to launch a brand new real-time lending feature to compete with digital startups. Right. They can use the symbiosis approach to launch just that specific new lending feature on the new essence platform. The old system handles the checking, the new system handles the lending. They remain competitive without betting the whole farm on a massive, risky IT overhaul.
SPEAKER_01Aaron Powell So once a bank finally has this modular house built, whether they are a startup launching in six months or a legacy bank slowly upgrading room by room, what do they actually plug into it? Because the infrastructure just paves the way for the brain.
SPEAKER_00That's true.
SPEAKER_01And the source pivots here to the ultimate upgrade, artificial intelligence.
SPEAKER_00Yes. The architecture we've discussed so far, the clean data flows, the microservices, that is all just the nervous system. AI is the intelligence that brings it to life.
SPEAKER_01How does Byron frame this in the interview?
SPEAKER_00Well, Byron notes that AI and advanced analytics are responsible for shifting banking from reactive service delivery to proactive, insight-driven engagement.
SPEAKER_01We hear words like proactive all the time, but the mechanics of it in banking are just wild.
SPEAKER_00They really are.
SPEAKER_01Think about it. Reactive banking is what we've all grown up with. You ask for your account balance, the bank spits out a number, you ask for a car loan, the bank runs a credit check and says yes or no. The bank just reacts to your specific prompts. Aaron Powell Right.
SPEAKER_00It's very transactional.
SPEAKER_01Exactly. Proactive banking is the AI quietly analyzing your cash flow in the background and realizing: hey, based on this customer's recurring subscriptions and an upcoming annual utility bill, they're going to overdraft next Thursday.
SPEAKER_00It sees the problem before you do.
SPEAKER_01Right. The AI then intervenes before you even realize there's a problem, perhaps by offering a pre-approved short-term microcredit line to cover the gap. The bank transitions from a heavy vault holding your money to basically a financial crystal ball predicting your needs.
SPEAKER_00And the entire industry is racing toward this reality. The interview actually cites specific data from the Financial Services State of the Nation survey.
SPEAKER_01What did the survey find?
SPEAKER_0061% of financial institutions reported improving their AI capabilities in the past year alone.
SPEAKER_01Wow. 61%.
SPEAKER_00Yeah, that is nearly double the figure from 2022. It is an exponential curve of adoption, not just a passing trend.
SPEAKER_01The interview details specific tools Canastra is rolling out to make this happen too. They have something called retail analytics, which is the engine driving those predictive actions. It handles cash flow forecasting, but also something called churn reduction. But how does an AI actually predict that I'm about to close my bank account and leave?
SPEAKER_00It looks for subtle behavioral patterns that a human teller would just never notice. Well, the AI might detect that for the last two months you've been routing$50 from your direct deposit into a new routing number at a competing bank. It recognizes the pattern of someone slowly testing out a new financial institution. Oh, that's sneaky. But smart. Very smart. Before you fully close your account, the AI alerts the retention team to offer you a personalized high-yield savings rate to win back your loyalty.
SPEAKER_01Okay, that's impressive. They also mention a generative AI conversational assistant called Essence AI Assist, which gives employees instant access to the platform's knowledge base.
SPEAKER_00Yes, that's a very cool tool.
SPEAKER_01But I have to ask the elephant in the room question here.
SPEAKER_00Go for it.
SPEAKER_01When you hear that 61% of banks are adopting AI, the immediate visceral fear is mass layoffs. We constantly hear about AI replacing human workers to ruthlessly cut costs. But this AI assist tool seems entirely focused on helping employees, not replacing them. Does CO Ben Byron address the human element of this shift?
SPEAKER_00She does, and she frames it entirely around human augmentation, not replacement. She refers to these tools as agentic AI assistance embedded across the value chain.
SPEAKER_01Agentic AI assistance. Got it.
SPEAKER_00Think about a loan officer at a mid-sized regional bank. Right now, that person might spend 70% of their workday hunting down applicant documents, verifying basic compliance rules against a massive manual, and navigating clunky software just to find a specific policy detail. It's tedious manual labor.
SPEAKER_01So it's less like replacing the loan officer with a robot and more like giving every single employee their own dedicated genius-level paralegal.
SPEAKER_00That's a great analogy.
SPEAKER_01A paralegal who can read the 500-page compliance manual in two seconds, summarize the applicant's risk profile, and just highlight the three most important factors.
SPEAKER_00Exactly. The human employee is suddenly freed from those mind-numbing routine tasks. They are empowered to make faster, better informed decisions. They shift from being simple data gatherers to acting as strategic financial advisors for their clients.
SPEAKER_01That sounds like a much better job, honestly.
SPEAKER_00It really is. And FNASTRA is actively mirroring this philosophy internally. The interview notes they are rolling out Microsoft co-pilot to their own workforce, launching extensive upskilling programs, and they even hosted an internal Gen AI learning festival.
SPEAKER_01Oh wow. So they're walking the walk.
SPEAKER_00Totally. They are actively changing their own corporate culture to match the technology they are selling to banks. In a landscape defined by rapid change, freeing up human cognitive capacity is the most valuable investment an institution can make.
SPEAKER_01So what does this all mean? When we step back and look at the deep dive we've just taken, it reveals a pretty fascinating truth.
SPEAKER_00What's that?
SPEAKER_01The future of banking isn't just about flashy mobile apps or, you know, introducing a cool new metal credit card. Yeah. It is about deep structural adaptability. Whether we are looking at Tonic scaling rapidly by letting business teams drag and drop new products, or Ourobank launching globally in six months through API partnerships, or legacy banks carefully upgrading their mainframes room by room using that symbiosis approach, the ultimate currency in modern finance is simply the ability to adapt to rapid change.
SPEAKER_00It represents a total shift from rigidity to elasticity. Moving forward, the financial institutions that survive and thrive won't necessarily be the ones with the thickest physical vault doors or the oldest brand names. They will be the ones with the most frictionless APIs and the deepest predictive insights.
SPEAKER_01And for you listening, these pillars that Finastra focuses on adapt, evolve, and thrive. They aren't just corporate slogans for multinational banks. They are actually a masterclass in how any professional can navigate a landscape of rapid technological shifts.
SPEAKER_00Absolutely.
SPEAKER_01You don't have to rip and replace your entire career when your industry changes. You can use the symbiosis approach. You can build your own microservices by adding new specialized skills, and you can leverage AI tools like a dedicated paralegal to augment your own capabilities and free up your mind for strategic thinking.
SPEAKER_00This raises an important question, though, as we look to the horizon.
SPEAKER_01Oh, what are you thinking?
SPEAKER_00Well, we've talked extensively about how core banking is successfully transforming into an open, frictionless platform with deeply embedded predictive AI. But if this technology continues to accelerate at an exponential rate, how long until banking Becomes entirely invisible to us.
SPEAKER_01Invisible.
SPEAKER_00Yeah. Will there soon be a future where your own personal AI assistant on your phone seamlessly negotiates with your bank's agentic AI behind the scenes? Oh man. Imagine it instantly moving your money across different microservices to capture the highest possible daily yield, or automatically securing the lowest interest rate on a microloan, all without you ever tapping a screen, opening an app, or stepping foot into a physical branch.
SPEAKER_01A completely autonomous financial life playing out quietly in the background, it changes the entire paradigm of what a bank even is.
SPEAKER_00It really does.
SPEAKER_01Next time you tap your phone to buy that cup of coffee, just remember the digital plumbing beneath the surface isn't just a series of static pipes anymore. It's rapidly becoming a living, breathing intelligence.
