Fixing KYC: The Hardest Problem in Private Banking, Jefferson Sun (xBanker.ai)

KYC is one of the most persistent challenges in financial services.

And in private banking, the problem is especially difficult.

At CFTE’s UK–Singapore Exchange, Jefferson Sun from xBanker.ai brought a practitioner’s perspective to a process that every financial institution knows well, but few have managed to make truly efficient: Know Your Customer.

His message was clear: KYC was never designed to scale.

A Process Under Pressure

KYC is essential to financial services. It helps institutions understand who their clients are, assess risk, meet regulatory obligations, and protect the integrity of the financial system.

But in practice, the process can be slow, fragmented, and difficult to manage.

Drawing from his experience running a multi-family office, Jefferson highlighted several issues that make KYC particularly challenging:

  • multiple back-and-forth interactions
  • inconsistent data quality
  • subjective decision-making
  • long onboarding timelines
  • high operational costs

In many cases, onboarding decisions can take months. By the time a client is approved, the opportunity may already be gone.

This is not only an operational problem. It is also a business problem.

For private banks, delays in onboarding can affect client experience, relationship management, and revenue opportunities. For clients, the process can feel repetitive, unclear, and frustrating.

Why KYC Is So Difficult to Scale

The challenge with KYC is not simply that it takes time.

The deeper issue is consistency.

Different teams may ask different questions. Different reviewers may interpret risks differently. Similar cases may lead to different outcomes. Information may be collected in different formats, across different channels, and with varying levels of completeness.

In a regulated environment, this creates real risk.

Financial institutions need to ensure that the same standards are applied every time. They need to identify the same risks consistently, document decisions clearly, and maintain an audit trail that can be reviewed when needed.

This is where traditional KYC processes often struggle.

They rely heavily on manual effort, institutional knowledge, and human judgement. While human expertise remains essential, the process becomes difficult to scale when every case requires repeated interpretation from the beginning.

Building a KYC Co-Pilot

To address this challenge, xBanker.ai developed a KYC co-pilot trained on real bank policies and hundreds of client cases.

The objective is not to remove humans from the process.

It is to support them.

The system helps perform analysis, improve consistency, and support human decision-making. It can help ensure that relevant questions are asked, risks are identified, and outputs are documented in a structured way.

Crucially, humans remain in control.

This is especially important in regulated financial services. AI can support analysis and reduce manual workload, but final responsibility must remain with professionals who understand the client, the institution’s policies, and the regulatory context.

The outputs also need to be auditable. In KYC, it is not enough for a system to produce an answer. Institutions need to understand how that answer was reached, what information was considered, and how the decision can be reviewed.

The Hardest Problem: Consistency

One of Jefferson’s most important points was that the hardest problem is not automation.

It is consistency.

In KYC, value comes from ensuring that the same questions are asked, the same risks are identified, and the same standards are applied every time.

This is difficult because KYC cases are rarely identical. Clients may have different structures, jurisdictions, sources of wealth, documentation, and risk profiles. The process requires judgement, but that judgement must be applied within a clear and consistent framework.

AI can help by bringing structure to the process.

It can support reviewers by identifying relevant information, comparing cases against policy, highlighting potential risks, and helping maintain a consistent approach across different onboarding journeys.

This is where AI becomes valuable: not as a replacement for expertise, but as a way to make expert processes more reliable.

From Faster Onboarding to Better Processes

The impact of this approach is significant.

According to the example shared, xBanker.ai’s KYC co-pilot can support:

  • faster onboarding
  • reduced costs of around $2,500 per case
  • improved consistency
  • stronger auditability
  • a more reliable process

The speed matters. The cost reduction matters. But the deeper value is reliability.

In regulated industries, faster processes are only useful if they remain controlled, explainable, and compliant. The goal is not simply to accelerate onboarding. It is to build a process that institutions can trust.

AI in Finance Requires Collaboration

Jefferson also emphasised an important point: meaningful AI in finance cannot be built alone.

KYC sits at the intersection of regulation, operations, technology, client relationships, and institutional risk. Building effective AI for this space requires collaboration between practitioners, banks, compliance teams, technology providers, and regulators.

The most valuable AI solutions in financial services will not be those built in isolation. They will be those shaped by real workflows, real policies, real cases, and real constraints.

That is what makes the KYC problem so important.

It is not a theoretical use case. It is a live operational challenge that affects institutions and clients every day.

The Takeaway

In regulated industries, scaling AI is not about speed alone.

It is about consistency, auditability, and trust.

Jefferson Sun’s perspective at CFTE’s UK–Singapore Exchange showed how AI can address one of the hardest problems in private banking by supporting better KYC processes, improving decision-making, and making onboarding more reliable.

The future of AI in financial services will not be defined only by what can be automated.

It will be defined by what can be made more consistent, more accountable, and more trusted.
