Checkly has secured $20 million in Series B funding led by Balderton, alongside existing investors Accel and CRV, to accelerate its development of code-first synthetic monitoring for modern DevOps, connecting OpenTelemetry to synthetics to help resolve issues 10x faster. The company aims to provide proactive monitoring that alerts engineers before users recognize performance and functional issues, using Monitoring as Code (MaC) to enable developers to configure, understand, and own the monitoring of their production services. With the introduction of Checkly Traces, the company is introducing OpenTelemetry traces to help engineers find issues, get alerted, and fix them 10x faster, reducing MTTR significantly. The funding will also be used to expand the team and enhance synthetics to proactively detect issues faster.
