This creates three major pain points. These systems:\n\n1. Adapt slowly to new fraud trends\n2. Are designed for point-in-time review and not continuous analysis of risk\n3. Result in a high number of false positives when patterns change, leading to lost revenue\n\nAs AI makes it easier to commit fraud, these gaps are leading to an explosion in losses.\n\n# **🐭🐱 Our Solution**\n\nMouseCat is dedicated to building the best AI platform for fraud investigation.\n\nMouseCat's agents conduct fraud investigation like a human would. They review internal case information, search for additional details from databases, APIs, etc., refer to prior cases for context, and distill the most important evidence needed to make a decision. MouseCat uses its insights to identify fraud rings and propose mitigations with new backtested rules/features.\n\nWith MouseCat, companies get:\n\n1. **Continuous Improvement:** Agents that continuously improve based on past cases and analyst feedback.\n2. **Continuous Review:** Post-transaction analysis to spot and mitigate fraud trends faster.\n3. **Custom Integration and Data Ownership:** On-prem deployments that integrate with customers’ existing data sources and APIs.\n\nPlus, MouseCat handles production hurdles like evaluation, monitoring, distributed failures / retries, and more.\\\n\\\nImagine if your best analyst could investigate every transaction...\n\n![uploaded image](/media/?type=post\u0026id=98387\u0026key=user_uploads/339225/c8837552-a055-4144-825d-68178cefa4b5)\n\n# **🙏 Our Ask**\n\nIf you answer “yes” to any of these, we’d love your help:\n\n* Can you introduce us to folks on fraud teams at banks / fintechs / marketplaces?\n* Are you leading a fraud team?
