In this exclusive interview, Serban Negrescu, Director of Digital Transformation and Product Development at Garanti BBVA, reflects on the future of banking in CEE and why real transformation means rethinking technology, culture, and trust together.
FINANCE LEGENDS
At UNCHAIN, the fortress is just the setting. The real story is the people. Finance Legends is a series that shines a light on the individuals whose choices and ideas leave a mark on the region’s financial landscape. Each edition looks at a leader whose work is influencing how banks, fintechs, and regulators think about progress and act on it. In this edition, the focus is on Serban Negrescu, the Garanti BBVA executive whose work in digital transformation raises some of the most pressing questions facing banks today.
Serban Negrescu has built his career on the idea that banking should always follow progress. At Garanti BBVA, he leads the push on digital transformation and product development, a role that puts him in the middle of one of the biggest questions in finance today: how do you keep the bank relevant when customers expect everything to happen instantly, on their phones, and without issues? In today’s market that challenge is amplified: customers are quick to embrace digital tools, yet institutions often struggle to keep pace. Serban sits at that fault line, pushing Garanti BBVA to move with the agility of a fintech while carrying the responsibility of a bank.
What does real digital transformation in banking require today, beyond the hype?
Real digital transformation in banking goes far beyond adopting flashy front-end apps or simply digitizing existing processes. It demands a deep, strategic shift across the entire organization, one that rewires both the technology stack and the operating model
At Garanti BBVA Romania, we are replacing our core systems with scalable, cloud-ready platforms that allow for faster integration, real-time data processing, and continuous delivery of new digital services. Old legacy systems are too rigid and slow to support the agility of today’s market demands.
So it starts with technology, but where does the customer come in?
Technology is only the foundation. Real transformation also means redefining how value is delivered to the customer. That starts with putting customer journeys at the center, not just digitizing offline processes but completely rethinking them to be intuitive, accessible, and efficient. In my experience, aligning business, IT, and data teams around this goal is key.a teams are all aligned around the same goal.
And what about culture inside the bank? Many institutions still struggle with risk-aversion.
A successful transformation also requires a culture of agility and experimentation. Traditional banks often struggle with siloed structures and risk-averse mindsets. To drive change, we need empowered, cross-functional teams, rapid feedback loops, and leadership that supports bold decisions. At Garanti BBVA, we’re fostering this by adopting agile methodologies and collaborative governance across departments.
You also mentioned data. How central is it to this transformation?
It’s critical. True digital transformation means becoming a data-driven organization, where insights guide decision-making, personalization, and operational efficiency. This goes beyond dashboards; it’s about embedding intelligence into every customer interaction and internal process.
All of these moving parts (technology, culture, data, and compliance) point to the same conclusion: digital transformation is a complete rethinking of how a bank operates. It takes leadership willing to make structural changes, teams willing to experiment, and above all, a constant focus on the customer.
How would you describe Romania’s progress in digital banking compared to other countries in Central and Eastern Europe?
It is a solid fact that Romania has made significant strides in digital banking, particularly in the past five to seven years, but its progress is a mixed picture when compared to other countries in Central and Eastern Europe (CEE).
On the positive side, Romania has seen strong innovation in mobile banking and fintech adoption. The local market responded rapidly to global trends like NFC payments, instant onboarding and lending, and mobile wallets. The appetite for digital experiences is there, and Romanian consumers are digitally savvy and willing to adopt new solutions quickly when the value is clear.
What role have banks played in that shift?
Banks (both local and subsidiaries of international groups) have invested heavily in core modernization and digital channels. Initiatives such as replacing legacy infrastructure, launching fully digital lending products, and integrating RPA or AI-based services are no longer exceptions, they are part of the new norm.
Still, progress has been uneven. Serban points out that while there are success stories, the pace and consistency of implementation lag behind markets like Poland or the Czech Republic. Many banks are still early in their digital journeys or working with fragmented strategies, which makes scaling harder.
Another weak spot is public digital infrastructure. In countries such as Estonia (and increasingly in Hungary), tools like digital IDs, electronic signatures, and open data have created the foundation for seamless financial services. In Romania, those pieces exist but remain underdeveloped or underused.
What about inclusion? Has digital closed the gap, or widened it?
That’s still a challenge. Financial inclusion and digital literacy continue to present barriers in rural or underserved communities. There’s a need for broader efforts across the ecosystem (banks, regulators, fintechs, and government) to ensure digital doesn’t widen the accessibility gap
Even so, Serban believes the fundamentals are strong: talent, appetite for innovation, and consumer readiness. What Romania needs now, he argues, is scale, speed, and closer cooperation between public and private players. Only then will the country be able to match (maybe even surpass) its peers in the region.
At Garanti BBVA, you have overseen fully digital onboarding and AI-powered personalization. What were the main lessons from implementing those capabilities?
One of the key lessons we learned is that digital onboarding and AI personalization are not technology projects. They are transformation enablers that require deep alignment across the business, IT, risk, legal, and customer experience functions.
What did you discover when it came to digital onboarding specifically?
The first major lesson was the importance of customer-centric design. It’s not enough to digitize forms or replicate the branch process online. We had to rethink the onboarding journey entirely, simplifying steps, eliminating friction, and ensuring compliance and security without compromising user experience. Getting KYC, digital signature, and identity verification to work seamlessly required intense collaboration between compliance and tech teams, and sometimes even regulatory dialogue.
That collaboration, he adds, was not just a technical exercise but a cultural shift inside the bank. Compliance and technology don’t always sit at the same table, and digital onboarding forced those conversations to happen in real time.
Did everything work smoothly from the start?
We realized the importance of agility and testing in live environments. What worked in pilot did not always scale as expected. We had to continuously monitor drop-off rates, customer feedback, and operational data to iterate quickly and optimize the funnel. Real transformation came from being willing to adapt and improve fast, even after launch.
And when it comes to AI personalization?
Personalization must serve a clear value to the customer, not just push offers. When used right, AI helps us anticipate needs, simplify navigation, and make financial decisions easier. But relevance is key. Irrelevant recommendations erode trust fast, so the AI has to be smart, explainable, and continuously trained.
The broader lesson was about ownership. Digital onboarding and personalization touched nearly every part of the bank. Success depended on breaking silos and aligning everyone around the same goal: creating a simple, intuitive, and meaningful customer experience. These initiatives, he says, are now treated less as standalone projects and more as pillars of a scalable digital bank.
Looking ahead, where do you think banks still fall short when it comes to delivering truly personalized customer experiences?
While many banks have made progress in collecting data and segmenting customers, most still fall short in translating those insights into real-time, context-aware, and emotionally intelligent experiences. Personalization today is often superficial, driven by marketing rules or product triggers, not by a true understanding of customer intent or life context.
What’s the core problem behind that?
One of the key shortcomings is that banks think in products, not in customer needs. Most personalization efforts still focus on pushing offers (a credit card when spending is up, a loan when income drops), but that’s not truly personal. Real personalization starts with anticipating behavior and offering relevant guidance, sometimes even before the customer realizes the need. That requires a shift from transactional thinking to relationship thinking.
Serban points out that this shift requires more than clever targeting. It means building an understanding of customers that cuts across silos, something most banks still struggle with.
Is data integration the missing piece?
Yes. Many banks still operate in silos, with fragmented views of the customer across channels and products. Without a unified customer profile (enriched with behavioral, transactional, and even contextual data), it’s impossible to deliver consistent and meaningful personalization. The data exists, but it’s often underutilized or locked in legacy systems.
Beyond data, what else gets overlooked?
Banks also underestimate the importance of timing and delivery. Personalization is not just what you say, it’s when and how you say it. A push notification during salary week can be relevant; the same message during a financial hardship moment can be tone-deaf. Understanding context and emotional state is critical, and AI can help, but only if designed and trained thoughtfully.
He adds that timing without trust doesn’t get far. Customers today are more aware of how their data is used, and if personalization feels intrusive or manipulative, it can backfire quickly. Transparency, control, and a focus on genuine financial well-being matter just as much as the sophistication of the algorithm.
So what will separate the leaders from the laggards in the years ahead?
I would say agility. By the time a personalized campaign is built, approved, and deployed, the moment of relevance has often passed. Embedding real-time intelligence into customer interactions (from app navigation to contact center conversations) is where the future lies. And that requires not just technology, but a cultural shift toward experimentation and continuous learning.
That shift, he argues, will define tomorrow’s leading banks.
How did you enjoy your time at UNCHAIN this year?
UNCHAIN this year was truly inspiring, both in content and in energy. It brought together exactly the kind of community we need more of in the region: bold thinkers, digital doers, and people genuinely passionate about reshaping financial services. What I appreciated most was the honesty of the conversations. It was less about buzzwords. It had actual substance. Whether it was about embedded finance, open banking, or AI in customer journeys, the discussions reflected a maturity that shows how far the ecosystem has come.
Part of the value was also personal. Stepping outside the day-to-day pressure of execution gave him space to reconnect with peers from fintechs, banks, and regulators across CEE. The mix of perspectives (and even the constructive disagreements) offered both validation for what Garanti BBVA is already doing and sparks for what could be improved.
Another standout for me was the diversity of voices, not just geographically, but also across disciplines. You had product leaders next to founders, data scientists next to policymakers. That kind of mix creates the right tension, and some of the most insightful conversations happened outside the formal panels, over coffee or during side chats.
Too many conferences stay in the clouds; Unchain managed to balance inspiration with practical use cases and lessons learned, including some failures, which are just as important to hear. All in all, it was time very well spent.
That sense of shared purpose also mirrors his own approach at Garanti BBVA. He has never spoken about technology as an end in itself, but as a means to build relevance and trust. Whether it’s digital onboarding, AI-driven personalization, or the broader cultural shifts inside banks, his message is that transformation only matters if it makes people’s lives simpler and more meaningful.
In a region still defining its digital future, transformation is not a showcase of technology but a test of relevance: whether banks can remain trusted, useful, and human while rethinking their foundations. Serban’s work at Garanti BBVA shows that the future of finance in Romania (and in the wider region) will belong to those who can turn ambition into execution without losing sight of the people they serve.
