About MouseCat
Summary
MouseCat builds an AI platform that detects, investigates, and acts on financial crime for banks, fintechs, crypto exchanges, and merchants. The system learns a company's own SOPs, historical data, and case notes, then autonomously reviews suspicious transactions, accounts, and counterparties end-to-end. It replaces the manual case review work done by human fraud and compliance agents, cutting investigation time and false positives across fraud, scams, AML, and abuse.
Go-to-market
Risk and compliance teams at Fortune 500 banks and large fintechs buy MouseCat through a sales-led motion, with the product deployed against live transaction data after an initial learning phase.
