Case Study: Winnow improves serverless visibility and cuts latency with Thundra

Winnow uses Thundra to monitor Lambda performance, cold starts, errors, and costs

Winnow, a San Francisco-based media/digital marketing startup, needed better observability for its rapidly growing AWS serverless architecture. With more than 70 Lambda functions, heavy data loads, and multiple third-party integrations across several programming languages, the team struggled to pinpoint failures and understand overall system health using CloudWatch and custom tools alone. Thundra was chosen to improve visibility into their serverless environment.

Thundra implemented automatic code instrumentation through a simple serverless framework integration, giving Winnow structured analytics and detailed tracing across Lambda performance, cold starts, errors, costs, and usage patterns. With Thundra, Winnow could identify the most costly and most memory-intensive functions, filter by environment, and discover bottlenecks that reduced latency by 35%. The solution became part of their daily development and maintenance workflow.
