Financial crime teams work across customer information, screening results, and activity. We’re building a more connected place to do that work.
Customer information lives in one system. Screening evidence lives in another. The activity that prompted a review arrives somewhere else. The team has to piece it together.
Dossiers OS is built around connected records. Onboarding, screening, monitoring, and investigations share the information needed to understand the customer relationship.
We build AI assistance around defined tasks, permitted tools, and review. The aim is to make the evidence easier to work with throughout the institution’s process.
Every review should build on what the team already knows: who the customer is, how their activity connects, and what the evidence establishes.
Our team brings together experience in software, data, research, and building products.
