Case Study: FactSet improves developer efficiency and reduces MTTR with Lightstep

FactSet Increases Developer Efficiency, Improves Workflows, and Reduces MTTR with Lightstep

FactSet, a financial data and analytics company serving more than 125,000 users, needed better visibility into a highly complex, high-traffic distributed system with hundreds of services, thousands of instances, and multiple languages. Its developers struggled to diagnose intermittent performance issues, understand deep dependencies, and find the root cause of problems that often appeared several layers below the application.

Using Lightstep, FactSet gained full-system observability with traces, Snapshots, correlations, and deployment health insights to quickly isolate issues across internal and third-party dependencies, even when errors were not logged. Lightstep helped FactSet reduce incident resolution time from one to two days down to three to four hours, improve mean time to innocence, and proactively resolve issues before they affected customers, while also benefiting from strong technical support from the Lightstep team.
