We are a group of observability and monitoring experts dedicated to a single mission. We strongly believe Observability should be easy to understand, use, install, integrate, and manage. We make Observability easy for every developer. We fully embrace OpenTelemetry, Prometheus, and open standards for modern observability. Our focus is on correlating and contextualizing issues to look beyond the limitations of telemetry silos. It should be easy for users to collect relevant telemetry and our goal is to have widespread adoption with a user-friendly and developer-friendly experience. We believe that more data doesnt always lead to more insights and often results in significant costs.
