Summary

Compliance teams shouldn't have to choose between staying compliant and moving fast.

Today, we're announcing our €6.5M Series A to close that gap. Our goal is to make compliance AI the standard way banks and fintechs fight fraud and financial crime, not a privilege only a few teams can afford.

The round is led by Smartfin, with participation from ADNEXUS and increased support from existing investors Passion Capital, 42Capital, and Hexa bringing our total raised to €9M.

What this means for compliance and FRAML teams

The regulatory bar keeps rising. Compliance teams are asked to do more with the same headcount.

Our job is to make sure that it is Marble that absorbs that complexity, not our customers.

Every cent of this round goes into making Marble do more of the heavy lifting for the teams who use it every day.

Compliance AI built directly into the workflow

When an alert needs a closer look, case investigation is assembled and pre-analyzed before your team opens it. Marble builds an SAR or STR with the click of a button that analysts review before filing. So a human stays accountable for every single judgment. In compliance, that's exactly the point.

From rule generation to alert triage, we're building compliance AI directly into the workflow. So analysts spend less time on repetitive review and more time on real risk decisions and oversight.

Transparent FRAML compliance software, deployed on your terms

Because the core is open-source, you can see exactly how every decision is made.

Compliance lives in the deepest data layers of a financial institution. That is why Marble deploys fully on-premise on infrastructure you control, integrating your data as it is without months of implementation projects. Your data, your structure, your organization.

Underneath, our FRAML compliance software handles the heavy lifting: data transformation, real-time checks, and high-volume screening, with AI agents that only ever touch the data they're permitted to.

Your most sensitive data never leaves your walls.

Fraud detection and rules that evolve with your business

Adapting your rules, workflows, and risk sensibilities shouldn't be a project.

Marble lets compliance officers set and change their own fraud detection logic. So the system evolves with the business – not on the next IT release cycle.

Every change stays audit-ready and traceable.

This is what AI for FRAML compliance should feel like: fast to change, easy to audit, and always in your hands.

Why now – the market is backing compliance AI

Financial crime is accelerating “thanks” to AI automation. Manual review can't keep pace.

The market knows it: according to Sifted, European RegTech funding is up 147.6% year-on-year to €1.5bn.

Marble is already in production at more than 100 banks and FinTechs across 25+ countries – proof that compliance AI works at scale, on the customer's own terms.

This round lets us bring it to many more.

This round is for the teams already in production

To every institution already trusting Marble in production: this round is for you.

And to the new partners joining us: let's build the compliance infrastructure the financial system actually needs.

Onward.
