Case Study: Start.io cuts MTTR by 50–60% with Lightrun

How Start.io slashed MTTR by 50%-60% with Lightrun on AWS

Start.io, a high-scale advertising technology company, processes more than 30 billion requests per day and struggled with hard-to-reproduce production issues, including concurrency, parallelism, and cache consistency problems. These incidents were difficult to diagnose in real time and often led to service disruptions, data corruption, and slow incident response.

Using Lightrun’s real-time debugging, monitoring, and alerting platform integrated into the IDE and deployed across production services on AWS, Start.io added visibility without changing code or leaving development workflows. Lightrun helped the team pinpoint issues faster, capture stack traces and conditions in live systems, and reduce mean time to resolution by 50%–60%, improving developer productivity and reducing incident resolution stress.
