Paris-based Marble raises €6.5 million to automate fraud and AML compliance with its no-code, open-source platform
Marble, a Paris-based open-source platform for fraud detection and anti-money laundering (AML) compliance, has raised €6.5 million in Series A funding.
The round was led by Smartfin, a European venture capital and private equity firm that invests in high-growth B2B technology companies. The round also saw participation from ADNEXUS and existing investors Passion, 42Capital and Hexa. The Series A round brings Marble’s total funding to €9 million, with TSIC listed among its existing investors.
“Marble makes automation the default, on the customer’s own infrastructure. Our conviction is that Marble becomes the structurally differentiated, modern financial crime operating system for mid-market banks and fintechs. That’s why we led this round,” said Saumitra Dubey, Partner at Smartfin.
Founded in 2021 by Arnaud Schwartz and Pascal Delange, both former Shine executives, Marble targets FRAML, the combined fraud and AML workload, with a solution tailored for FinTech companies and financial institutions. The founders say they ran this work from the inside at the French FinTech and found that available tools added another layer rather than removing manual effort.
To overcome the compliance burden, Marble has designed a no-code platform that lets compliance and risk teams build their own transaction monitoring rules without waiting for a vendor or IT department. It also covers sanctions and watchlist screening, investigation and reporting, customer risk scoring, and A/B testing of rules on live data.
It can be deployed on-premises or as SaaS, and its open-source core lets auditors inspect how decisions are reached. According to the company, it protects more than three billion transactions annually and cuts manual review work by 90%.
“Compliance teams shouldn’t have to choose between staying compliant and moving fast. That’s exactly what we built Marble to solve. As the regulatory bar keeps rising, compliance teams are expected to do more with the same headcount. Our job is to make sure that it is Marble that absorbs that complexity and not our customers,” said Schwartz, CEO and co-founder of Marble.
Marble says it already runs in production at more than 100 institutions across more than 25 countries. With nearly 70% of its customers outside France and 70% of them choosing Marble to replace an existing solution, the company is targeting more than €5 million in annual recurring revenue by 2027.
The capital will go towards embedding AI deeper into compliance workflows and speeding up deployment at banks and FinTechs. Marble says it plans to deploy the funding to deepen four areas: AI-powered automation, faster deployment, agentic compliance, and adaptable systems.
It will build AI into rule generation, alert triage and case investigation, and speed up deployment through on-premises installs that integrate with a bank’s existing data rather than requiring months of transformation work. It is also developing built-in AI agents that access only the data they are permitted to use. Finally, it aims to make rule and workflow changes a routine configuration task for compliance officers rather than a new technology project.
Marble aims to make automated, AI-powered compliance a standard rather than a project few companies can run efficiently. “More than 100 institutions now run Marble in production. When conviction meets execution like that, it’s simple: you lean in,” said Will Orde, Partner at Passion Capital.
