Open‑source platform Marble secured €6.5 million in Series A funding to expand its AI‑driven fraud detection and anti‑money‑laundering solutions for banks and fintechs.

Paris‑based fintech security startup Marble has closed a €6.5 million Series A round to accelerate the rollout of its open‑source, no‑code platform that automates fraud detection and anti‑money‑laundering (AML) compliance for banks and fintechs.

Funding round details

The round was led by Partech Partners with participation from existing investors VentureCap and Angel Investors Network. Marble will use the capital to expand its engineering team, enhance AI models, and grow its go‑to‑market operations across Europe.

Why Marble’s solution matters

Traditional AML and fraud‑prevention tools rely on rule‑based systems that require extensive manual tuning. Marble’s platform leverages machine‑learning algorithms that continuously adapt to emerging threats, while its no‑code interface lets compliance officers design and deploy detection workflows without deep technical expertise.

The solution is also open source, allowing banks to audit the codebase, contribute improvements, and avoid vendor lock‑in—a growing demand among regulated institutions seeking transparency and cost efficiency.

Target market and growth strategy

Marble is focusing on mid‑size banks and fast‑growing fintechs that need scalable compliance tools without the overhead of legacy systems. The company plans to launch a SaaS offering in Q1 2027, complemented by professional services for custom model training.

  • Expand engineering and data‑science teams
  • Introduce a subscription‑based SaaS tier
  • Forge partnerships with European banking consortia
  • Scale sales efforts in France, Germany, and the Nordics

Industry reaction

Analysts note that Marble’s open‑source approach could pressure incumbent vendors to lower prices and accelerate innovation. “The blend of AI, no‑code flexibility, and community‑driven development is a compelling proposition for regulators and financial institutions alike,” said a senior analyst at Financial Times.

Marble’s platform democratizes advanced AML capabilities, making them accessible to firms that previously could not afford enterprise‑grade solutions.

The funding round underscores continued investor appetite for regulatory‑tech solutions that combine cutting‑edge AI with operational simplicity.
