Unit21 provides AI risk infrastructure for fraud prevention and anti-money laundering operations. Its platform combines real-time fraud detection, AML transaction monitoring, device intelligence, customer risk scoring, watchlist screening, and case management. The system can ingest transaction, behavioral, device, and customer data to identify suspicious activity and provide risk signals that organizations can use in automated decision workflows. A major focus of Unit21's current platform is its AI-agent functionality. These agents can perform tasks such as alert triage, evidence gathering, case investigation, entity and network analysis, and regulatory filing preparation. Unit21 says its AI agents learn from analyst decisions and can help reduce false positives and investigation time while producing reviewable outputs and audit trails. Unit21 was founded in 2018 by Trisha Kothari and Clarence Chio and is headquartered in San Francisco. It is designed primarily for financial institutions, fintech companies, marketplaces, neobanks, payment companies, and other organizations that need configurable fraud and AML infrastructure.
