Client Snapshot & Challenge

Gemba is a rapidly expanding neobank and white-label banking provider offering comprehensive payment ecosystems, including card accounts and transfers. As a regulated entity handling sensitive financial infrastructure, their growth hit a "SaaS Ceiling" with their previous provider, SumSub.

Their search for a new solution was driven by three requirements:

• Data Sovereignty: The ability to deploy the solution entirely On-Premise to ensure maximum security within their own infrastructure.
• Transparency and flexibility: Total transparency and control on their detection logic, with ability to create and adapt detection to their needs.
• Sustainability: A tool that could support their rapid growth without prohibitive cost barriers, and without breaking as the business evolves.

The Solution

Gemba chose Marble for its ability to deliver a fully on-premise deployment combined with an open, engineering-friendly architecture.

Data sovereignty and ease of setup

Gemba’s team were able to dig in Marble open source and validate the tool’s relevance before conversation even started, quickly confirming the alignment between the two companies.

Gemba and Marble share a strong technical DNA, where control and transparency are non negotiable requirements in everything they do.

Their go live schedule talks to the two companies alignment by itself:

• In one week, Marble was deployed on-premise, ready for the compliance team to jump start.
• In two weeks, the first detection program was built and the team could start shadow-testing and optimising their scenarios on live transactions, in parallel of their existing set up.
• In less than a month, the program was optimised and live in production, with false positives down to less than 2%.

Transparency & flexibility

As every professional working in Fraud or Compliance, Gemba had specific risks they wanted to track, which they just could not do with the fixed, rigid architecture of their existing tooling. This is where Marble’s radically different approach had the most impact.

Unlike any other tool on the market, with Marble, Gemba was able to create their own custom data model in Marble - mirroring their data warehouse - to feed their new Transaction Monitoring program.This means bringing-in any data, 1st or 3rd party, in its original format: no painful data transformation, no rigid set up unfit for their needs. Custom and flexible by design.

From this powerful base, they could create a detection program tailored to their business in just a few clicks.

Alexander Legoshin, Gemba's CEO, explains:

What I like the most with Marble is flexibility. In other tools, you don't understand what is going on behind the scenes which ends up lacking precision and possibilities to troubleshoot your detection programs.
With Marble everything is transparent and you can basically do anything you want, with all your data.

The team also leveraged Marble API-first architecture to build automations that drastically reduced manual workload.

For example high-risk sanction matches automatically triggers document request to the client, and once received the system attaches the documents to Marble case for review.This automation eliminated manual email chasing, allowing the AML team to focus solely on high-value decision-making.

Thanks to Marble unique approach to flexibility, Gemba teams are confident that no matter how their business evolves or how regulations tighten, the platform can adapt.
