Paris-based Marble has raised €6.5m in Series A funding for its open-source fraud detection and anti-money-laundering compliance platform. Smartfin led the round, with new investor ADNEXUS and increased backing from Passion Capital, 42Capital and Hexa. The financing brings Marble's total raised to €9m and will support more AI automation, faster on-premise deployment and sales to larger financial institutions. The Next Web · Dealroom
Letting compliance teams change the system themselves
Banks, fintechs and payment providers must continually adjust how they detect fraud, screen customers and investigate alerts. Traditional systems can turn each new rule, data source or workflow into an engineering project. Marble gives risk and compliance teams a configurable rule builder, transaction monitoring, screening and case management on an open-source core. Customers can use the hosted service or run it on their own infrastructure when governance and data requirements demand tighter control. Marble documentation · Marble infrastructure
That deployment choice is central to the commercial pitch. Compliance data is sensitive, integrations sit close to transaction systems, and institutions need to explain how decisions are made. An inspectable core and on-premise option can lower the architectural and governance barriers to switching, while configuration lets compliance officers alter rules without waiting for a new implementation cycle. Marble says 70% of its customers moved from another system, evidence that the company is competing for replacement budgets rather than only serving newly regulated teams.

The company says more than 100 institutions across over 25 countries use Marble in production, with nearly 70% of customers outside France. It is targeting more than €5m in annual recurring revenue by 2027. Those figures are company-reported, but they make the next execution step concrete: move from a developer-friendly open-source entry point into larger regulated accounts without losing the configurability that helped customers switch. The Next Web
Marble plans to use AI for writing detection rules, sorting alerts and supporting investigations, while limiting agents to the data and permissions they are allowed to access. The useful distinction is between automating repetitive review and preserving accountable human decisions. If Marble can keep that boundary legible to compliance teams, AI becomes part of an auditable workflow rather than a black-box replacement for analysts. The Series A finances the infrastructure and enterprise deployment work needed to make that promise credible at higher volumes. Marble product update · The Next Web
