This deep integration with your commerce and payment data ensures financial decisions are based on current performance, not outdated snapshots.

Retention Intelligence & Churn Prediction

Finsi OS proactively identifies at-risk customers before they cancel.

This module allows you to build precise customer segments using simple, natural language commands (e.g., "customers who bought in the last 30 days but haven't opened an email").
