MouseCat is an AI-native financial-crime platform that uses AI agents and proprietary risk models to investigate suspicious activity continuously rather than only evaluating transactions at the point of payment. Its system ingests historical and live event data, builds a tenant-specific risk representation of users, identifies risk vectors, investigates cases, detects fraud rings, and recommends mitigations. MouseCat provides APIs for event ingestion, decisioning, and risk embeddings, alongside configurable rules, backtesting, evaluation, and private-cloud deployment. The platform is designed for banks, fintechs, marketplaces, and other organizations managing fraud and compliance risk. MouseCat launched in 2026 and is currently active.
