Marble, a Paris-based startup, has secured 6.5 million euros in a Series A funding round led by SMARTFIN, with additional contributions from ADNEXUS, PASSION CAPITAL, and 42CAPITAL. This brings the company’s total funding to 9 million euros. Marble develops an open-source platform designed to detect financial fraud and ensure compliance with anti-money laundering (AML) and terrorist financing (FT) regulations. The platform is intended to replace traditional tools that are often seen as too slow to adapt to new risks and regulatory changes. Founded by Arnaud Schwartz and Pascal Delange, Marble’s platform offers a more flexible and configurable compliance infrastructure. This allows financial institutions to adapt to changing risks without undertaking lengthy IT projects. The platform includes a real-time decision engine that monitors transactions, filters AML risks, manages investigations, and modifies detection rules. Its open-source design allows institutions to retain control over their data and integrate their own know-your-customer (KYC) tools and sanction list suppliers. The European AMLR regulation, which will take effect on July 10, 2027, is expected to increase demand for such solutions. The regulation introduces a set of rules directly applicable across the European Union, while a new European authority, AMLA, will enhance oversight of the sector. This regulatory deadline is anticipated to prompt financial institutions to review the effectiveness of their controls, policies, data, and systems. Marble’s approach addresses concerns about data residency and model control by proposing deployment on the client's own infrastructure. This keeps transaction and investigation data within the institution’s environment. The company states that more than 100 institutions are currently using its platform across 15 countries, with nearly 70% of its customers located outside France. Approximately 70% of these customers chose Marble to replace existing solutions. The startup faces competition from both established players such as NICE ACTIMIZE, ORACLE Financial Crime and Compliance Management, SAS, FICO, BAE SYSTEMS NetReveal, and FISERV, as well as newer specialists like COMPLYADVANTAGE, NAPIER AI, HAWK AI, THETARAY, and LUCINITY. HAWK AI is noted as a significant European competitor in transactional monitoring and explainable AI. Marble plans to use the raised funds to automate rule production, improve the processing of alerts and investigations, integrate agents into workflows, and strengthen customer deployment capabilities. The company aims to exceed 5 million euros in annual recurring revenue (ARR) by 2027 by transitioning its current user base to enterprise contracts with the necessary support, security, connectors, and governance. The need for explainability in AI models is emphasized, as compliance requires traceability and justification for decisions before auditors, regulators, or risk management teams. This requirement is also found in AI deployments across other regulated sectors.
