Marble, a Paris-based open-source fraud detection and anti-money laundering compliance company, has raised €6.5 million in a Series A funding round led by Smartfin. The investment brings the company’s total funding to €9 million and includes new investor ADNEXUS, alongside continued backing from Passion Capital, 42Capital, and Hexa. Marble serves banks, fintechs, and payment providers that need to detect fraud and meet regulatory compliance obligations.
Series A Investment and Total Funding
Smartfin led the Series A round, with ADNEXUS joining as a new investor in the company. Existing investors Passion Capital, 42Capital, and Hexa each increased their investments as part of the round. Marble has now raised €9 million in total funding to support its expansion plans across Europe and beyond.
Platform Capabilities and Deployment
Marble provides a platform that allows risk and compliance teams to create, test, and launch detection rules without waiting for lengthy IT projects. The software can run on a customer’s own servers or as a hosted service, giving regulated institutions flexibility in how they manage data. This approach helps banks, fintechs, and payment providers respond more quickly to evolving fraud and compliance requirements.
Market Traction and International Reach
More than 100 institutions in over 25 countries currently use Marble in their production processes, according to the company. Nearly 70% of its customers are located outside France, and 70% of them made the switch from another system. This international footprint highlights demand for flexible compliance tools in a competitive market.
Cost Savings and Revenue Ambitions
Marble’s sales pitch focuses on reducing operational costs, with the company estimating that fraud and anti-money laundering tasks can consume 10% to 15% of staff time at banks and fintechs. The company argues that customers would prefer to redirect that time toward growing their business. Marble aims to achieve annual recurring revenue of more than €5 million by 2027.
AI Roadmap and Product Development
The new funding will push artificial intelligence deeper into compliance workflows, including writing rules, sorting alerts, and investigating cases. Marble also plans faster on-premises deployments that plug into existing data and built-in AI agents limited to the data they are cleared to see. Compliance officers will be able to change rules through configuration rather than engineering work.
Investor and Leadership Commentary
Arnaud Schwartz, CEO and Co-Founder of Marble, said, "Compliance teams shouldn’t have to choose between staying compliant and moving fast." He added that the company was built to absorb regulatory complexity so customers do not have to. Will Orde of Passion Capital said the team had delivered on its promises since the seed stage, while Smartfin Partner Saumitra Dubey described automation for fraud and anti-money laundering as having moved from niche to inevitable.
With its Series A funding secured, Marble is positioned to expand its open-source compliance platform and support more financial institutions in managing fraud and anti-money laundering obligations. The company’s emphasis on AI-assisted workflows, faster deployments, and configurable rules addresses a growing regulatory burden. By combining operational efficiency with measurable revenue targets, Marble aims to become a central player in the evolving compliance technology market.
