Who is Fourthline for?

Fourthline is aimed at banks and fintechs. It fits work such as identifying and verifying customers during onboarding (KYC/KYB, document checks, liveness), monitoring transactions for money laundering and terrorist financing, reducing false alerts, and screening customers and payments against sanctions lists, PEPs and adverse media.

What should I watch out for with AI in banks & fintech?

You process identity documents, biometrics and transaction data: choose providers with EU data location, ISO 27001 and a data processing agreement, and ask whether customer data is used to train the provider's models. Outsourcing critical processes falls under the DORA and EBA rules, so secure exit and audit rights in writing. Creditworthiness assessment of natural persons is a high-risk application under the EU AI Act. For transaction monitoring, the supervisor expects you to explain why an alert is or isn't triggered, a human to decide on a report to the FIU, and that you test the model for unequal treatment of customer groups.
