Andreii Bruiaka: Everyone Owns an App. Almost Nobody Owns the Engine
Andreii Bruiaka — entrepreneur, founder of Onicore.io, visionary.
1. Most people see fintech as beautiful apps and seamless experiences. You look beneath the interface. What do people fundamentally misunderstand about modern financial products?
People confuse the steering wheel with the engine. They think that if an app has a slick dark mode and instant notifications, it’s a technological breakthrough. They don't realize that fintech is 10% design and 90% plumbing. Underneath that beautiful interface is a brutal matrix of legacy clearing networks, regional ledger databases, and multi-layered compliance gates. True innovation isn't making a button prettier; it’s ensuring that when a user presses it, the money actually moves safely across borders without getting trapped in a systemic black hole.
2. You introduced the Infrastructure Transparency Framework. Was there a specific moment or crisis that made you realize the industry had a blind spot?
The turning point was watching how easily a mid-tier processing glitch could paralyze hundreds of seemingly independent platforms. I saw a minor routing configuration error at an upstream provider cascade downward, freezing payouts for thousands of businesses who had no idea what a "payment orchestrator" even was. They just knew they couldn't pay rent. That was the moment of realization: the industry has a massive blind spot regarding dependency chains. Founders were building digital skyscrapers on top of rental quicksand without mapping their structural risks.
3. You’ve said many fintech products own far less than they think they do. What was the most surprising example you’ve seen?
The most striking examples are neobanks or card programs that boast about their "revolutionary core," but in reality, they don't even own their ledger. If you peel back the layers, they are renting a license from a sponsor bank, using a third-party middleware to sync balances, relying on an external API for KYC, and outsourcing fraud detection. They own the brand and the database of user emails. If their core provider changes its terms or goes under, these "revolutionary" companies literally cease to exist overnight because they don't own a single yard of the actual financial rails.
4. What is the biggest illusion founders have when they say: “We built our own product”?
The illusion of autonomy. In 95% of cases, when a fintech founder says, "We built our own product," what they actually mean is: "We wrote clean code that connects to someone else's APIs." They confuse integration with creation. Building a product means you control its failure points. If your system relies on an external API that can change its documentation, raise its prices, or lose uptime without your consent, you didn't build a product—you built a very sophisticated wrapper.
5. At what point does convenience become dangerous dependence?
The moment you stop building redundancy because the single-provider solution is "too easy to pass up." Convenience is a drug in product development. It’s incredibly tempting to use a single monolithic BaaS (Banking-as-a-Service) provider that handles your KYC, ledger, card issuing, and processing all in one neat package. But that convenience turns into dangerous dependence when you realize you have zero leverage. If that provider fails, or if a regulator steps into their office, your entire business is wiped out instantly because you have no backup routing.
6. Modern fintech stacks rely on sponsor banks, payment processors, KYC, AML, middleware. Are we building innovation - or just stacking complexity?
Right now, a lot of the market is just stacking complexity and calling it innovation. We’ve built a Jenga tower of financial dependencies. You have a frontend app, talking to a middleware provider, who talks to a BaaS platform, who connects to a sponsor bank, which clears through the central bank. Every single layer takes a fraction of a cent, adds milliseconds of latency, and introduces a unique regulatory risk. True innovation is about subtraction, not addition. At Onicore, we try to compress that stack—to orchestrate the chaos rather than just adding another layer to the pile.
7. When infrastructure fails, users blame the visible brand. Is reputation becoming disconnected from control?
Absolutely, and this is the great tragedy for consumer brands. If an upstream clearing bank suffers an outage, the end-user doesn't know or care about that bank. They open their app, see an error screen, and instantly torch the fintech's reputation on social media. Fintech companies are taking 100% of the reputational risk while holding maybe 20% of the actual operational control. It’s a dangerous asymmetry, and the only way to fix it is to take control of your routing infrastructure so you can bypass failures before your users ever notice them.
8. Do fintech founders today understand their systems deeply enough - or are they becoming operators of black boxes?
Too many are becoming operators of black boxes. The ease of modern API integration has created a generation of founders who treat infrastructure like magic. They plug in a token, the data flows, and they don't ask questions. But when you don't know how the engine works, you can't fix it when it breaks. A founder managing millions of dollars needs to understand the technical and regulatory mechanics under the hood - from AML transaction monitoring logic to settlement windows. Otherwise, you’re just a passenger in a car you claim to be driving.
9. You mentioned that multiple companies can unknowingly share the same underlying risks. Could fintech face its own version of a systemic domino effect?
It’s not just a possibility; it’s already happening in micro-bursts. Because the fintech ecosystem has consolidated around a few "darling" infrastructure providers for KYC, ledger management, and processing, hundreds of competing apps share the exact same single point of failure. If one dominant KYC provider goes down or faces a regulatory freeze, it doesn't just affect one app – it simultaneously cripples twenty major platforms across the industry. It’s a systemic contagion that the market heavily underprices.
10. The BaaS collapse froze millions in customer funds. What did that incident reveal about the industry that people missed?
It revealed that the industry had completely decoupled compliance accountability from technological speed. People missed the fact that the collapse wasn't a failure of code; it was a failure of integrity. Companies were scaling customer acquisition at breakneck speeds while treating regulatory compliance as a secondary, back-office annoyance. The collapse proved that in finance, you cannot outsource your conscience. If you don't deeply understand and audit the compliance mechanics of your infrastructure partners, you are risking your customers' assets on a gamble.
11. If tomorrow a critical infrastructure layer disappeared globally - what breaks first?
Cross-border commerce would grind to a halt within minutes. Specifically, the settlement and reconciliation layers. If the underlying networks that verify ledger balances and handle FX conversion corridors between regional banks disappeared, your card wouldn't work at a local grocery store, let alone for an international SaaS subscription. The frontend apps would still open, showing beautiful balances, but the money would be completely trapped. It would reveal instantly that cash flow is an illusion without infrastructure flow.
12. We increasingly talk about AI risk. But could infrastructure risk quietly become the bigger story?
Infrastructure risk is definitely the bigger, more immediate story. AI risk is a sexy headline - it's philosophical and futuristic. Infrastructure risk is boring, unglamorous, and incredibly dangerous right now. If an AI model hallucinating hurts a product feature, that's a bad day. If a core ledger architecture fails or a systemic processing node collapses, that destroys businesses, freezes payrolls, and erodes trust in the digital economy. We are focusing on the ghost in the machine while ignoring the fact that the machine itself is rusting.
13. Do regulations reduce complexity - or unintentionally create more layers and dependencies?
They almost always create more layers. Regulators look at a problem and add a new reporting or compliance requirement. Fintechs, instead of rebuilding their systems, simply plug in a new third-party compliance tool to satisfy the regulator. Now you have a dependency on top of a dependency. Regulation is necessary, especially in payment security and AML, but when it’s prescriptive rather than principle-based, it turns fintech architecture into a bureaucratic puzzle instead of a streamlined financial tool.
14. Which fintech trend today looks exciting on the surface but worries you underneath?
The hyper-trend of "instant everything" - instant credit, instant cross-border settlement, instant onboarding. On the surface, it’s amazing for user experience. Underneath, it worries me because true risk assessment takes time. When you compress a transaction window to milliseconds, you are heavily relying on automated fraud models that can be gamed at scale. If your automated compliance architecture isn't flawlessly designed, "instant" just means you are letting fraud scale at the speed of light.
15. What’s one infrastructure weakness most founders won’t discover until it’s already too late?
Reconciliation debt. When you’re small, matching your internal database balances with the actual cash sitting in your partner banks is easy. But as you scale to thousands of transactions a minute across multiple countries, discrepancies inevitably crawl in due to network timeouts or currency fluctuations. If you don't build automated, real-time ledger reconciliation into your architecture from day one, you will wake up in two years to find a multi-million dollar hole in your accounts that will take months of forensic engineering to trace.
16. How should startups think differently before integrating a third-party provider?
They need to ask one brutal question: "What is our Day Two plan when this provider shuts us down?" Don't just look at their API documentation and their sales deck. Look at their SLA penalties, look at their regulatory history, and most importantly, design your system architecture so that you can decouple from them if you have to. Treat every third-party integration not as a permanent marriage, but as a temporary alliance.
17. In five years, what will fintech companies audit that almost nobody audits today?
They will audit Dependency Health Mapping. Right now, companies audit their financial books and their cybersecurity code. In five years, they will be forced to audit their entire operational ecosystem—mapping out exactly how many layers deep their data and money flows go, testing the regulatory resilience of their fourth-party and fifth-party providers. We will move from auditing what we own to auditing what we rely on.
18. What invisible system or dependency do you think shapes our lives more than people realize?
The global routing protocols of correspondent banking. Most people have no idea how a dollar gets from an account in New York to a business in a developing market. They don't know what SWIFT is, or how regional clearing houses operate. Yet, the efficiency, speed, and cost of those invisible plumbing lines literally dictate the price of imported goods, the survival of cross-border businesses, and the economic mobility of entire nations. It is the invisible nervous system of global civilization.
19. Outside fintech: what part of the future excites you the most?
The intersection of decentralized energy grids and edge computing. The idea that we can move away from massive, vulnerable centralized power sources and data centers toward hyper-localized, self-sustaining infrastructure nodes. It mirrors exactly what I believe about finance: true resilience comes from distributing power and intelligence to the edges, making the system impossible to take down from a single point of failure.
20. Final REVELATIONS question: What is something you understand today that the rest of the world will only realize later?
The world will realize that sovereignty is moving from entities to architecture. In the past, power belonged to the company with the biggest bank account or the country with the tightest laws. In the digital future, true sovereignty and control belong to whoever designs and controls the orchestration layer. If you control the rules of how data and money are routed across borders, you are the one setting the agenda. The interface is just theater; the architecture is where the actual power resides.
