Assessment
Unit21 is used by banks, credit unions, and fintechs that run their own fraud and AML programs. The company says it serves more than 200 customers in 90 countries, including Chime, Green Dot, Intuit, Sallie Mae, and Crypto.com, and its best use cases are transaction monitoring, case management, SAR workflows, and AI agents that work alerts. Pricing is quote-based, and its main competitors are Sardine, Flagright, and NICE Actimize.
Trisha Kothari and Clarence Chio founded Unit21 in 2018, and its first customers were Coinbase and Intuit. It raised a $45M Series C in June 2023, and total funding is close to $100M. In April 2026 founding engineer Tyler Allen became chief executive and Kothari became Chairman. The company says customers file about 5% of US suspicious activity reports through it.
It fits a risk team that wants to write its own rules and run investigations in one place. It is a weaker fit for a company that only needs document and selfie checks at signup, and for a buyer that wants posted prices before a sales call.
Rating by criterion
We score each of the eight criteria out of 100.
Sector criteria
Pair it with an identity vendor for document checks. Unit21 is strongest after onboarding, where transactions and behavior are monitored.
Run rules, models, and AI agents across fraud and AML events. The company reports billions of events processed each month.
Investigate alerts and file SARs from one case manager. Workflows, queues, and audit trails are core to the product.
Expect support for US bank and fintech exam needs. Customers include regulated lenders and card programs.
Vendor criteria
Track the AI agent roadmap. 2026 product updates focus on agents that triage and summarize alerts.
Plan a sales-led rollout with data integration work. Larger programs take weeks to tune rules.
Ask for a written quote. No public price card is posted.
Negotiate by event volume and modules. Multi-year terms are common for bank-grade monitoring.
