Thomson Reuters LegalTracker

Thomson Reuters LegalTracker (formerly Serengeti Tracker) is the dominant SaaS enterprise legal management solution, specifically engineered for corporate legal departments to manage matters, control external legal spend, and optimize outside counsel relationships. By 2026, LegalTracker has deeply integrated Thomson Reuters' 'CoCounsel' AI layer, transforming it from a system of record into a system of intelligence. The platform's technical architecture centers on the LEDES (Legal Electronic Data Exchange Standard) for global e-billing, supporting over 100 currencies and intricate tax requirements. It leverages a cloud-native infrastructure that facilitates secure collaboration between corporate counsel and thousands of law firms worldwide. Key to its 2026 market positioning is the 'LegalTracker Advanced' module, which utilizes machine learning to automate the audit of incoming invoices against billing guidelines, predicting potential overages before they occur. The solution remains a cornerstone for Fortune 500 legal teams, offering a unified data lake for legal operations that integrates seamlessly with enterprise ERPs like SAP and Oracle, as well as document management systems like iManage and NetDocuments.
