Sardine secured a digital-banking fraud partnership with National Bank of Canada, and NAventures led a US$25 million Series C extension taking total capital raised to about US$170 million, BusinessWire reported on 20 May 2026.
Banks are pairing fraud platforms with capital relationships that also put the vendor inside production risk workflows. Buyers still need proof that AI agents cut alert queues without weakening audit trails.
Sardine sells device intelligence and agentic risk tooling for fraud, AML and credit. The National Bank deal extends a Series C path that began with a US$70 million round led by Activant Capital in February 2025.
Risk and compliance leaders should demand measurable alert-clearance gains on their own volumes — and clear human-override paths — before treating any AI risk partnership as a completed fraud-ops redesign.
