Causal, a business and financial planning platform, uses Sentry for performance monitoring and error tracking, automating certain instrumentation processes while allowing custom implementation to address unique business needs. The team has seen built-in solutions free up developer time and customizable instrumentation help solve complex problems. They use distributed tracing to identify root causes of issues, such as slow transactions on the frontend or backend, and have recently solved a problem with a user's model taking longer than expected to evaluate. Sentry provides visibility into performance and allows the team to get a general overview of how their app is performing across different stages, enabling them to proactively address performance issues over time.
