Letgo, a mobile app for buying and selling second-hand goods, faced challenges in managing its error resolution process due to tool sprawl with its previous logging tools. The company migrated from an ELK Stack to New Relic One, which streamlined its troubleshooting process by providing a single, high-level view of its Kubernetes clusters and allowing teams to quickly navigate to specific transactions within apps. With New Relic One, letgo's product team can now focus on developing and scaling their software instead of managing external systems, resulting in faster, simpler troubleshooting in just a few clicks.
