Marble Raises €6.5M for Fraud Automation

Marble has raised a Series A to give financial-crime teams more direct control over fraud and anti-money-laundering systems that are often difficult to customise.

What happened

The Paris-based startup raised €6.5 million in Series A funding led by Smartfin, with ADNEXUS and existing investors Passion, 42Capital and Hexa participating.

Marble offers an open-source, no-code platform for transaction monitoring, sanctions screening, fraud detection and customer-risk scoring.

The company says its platform processes more than three billion transactions annually and reduces manual review significantly. Those metrics are company-reported.

Why it matters

Financial-crime teams often depend on rigid vendor systems that generate large numbers of alerts but are difficult to adapt.

That leads to expensive manual review.

A configurable platform can let compliance teams change rules and workflows without waiting for vendor engineering cycles.

Open-source architecture can also make the underlying logic more transparent.

The bigger picture

AI and automation are moving deeper into compliance, but explainability remains essential.

Banks and fintech companies need to know why a transaction was flagged and demonstrate that logic to regulators.

That favours systems that combine automation with clear rules and audit trails.

Marble's round reflects the continuing demand for infrastructure that makes financial crime detection more flexible without turning the decision process into an opaque black box.
