Founders & story · from Fourthline’s own dossier

Fourthline emerged from the SafeNed neobank stack in the Netherlands and refocused as a pure-play European KYC/AML RegTech in 2018. Since then it has built a modular identity and AML platform serving banks, neobanks, neobrokers, and embedded-finance platforms across 30+ jurisdictions, positioning around locally-compliant onboarding as European AMLR (2027) takes effect. Its 2026 combination with Veridas signals a shift from a European-regional player to a global identity infrastructure vendor.
