Dash0, the New York observability startup valued at $1 billion, has acquired Berlin’s Polar Signals to bring continuous profiling into its platform and feed the data to AI agents.
Continuous profiling shows developers exactly where code consumes computing power and memory, and where applications slow down or get expensive. Dash0 plans to embed that visibility in its monitoring stack so teams can trace performance issues down to individual functions and lines of code.
The deeper play is agentic. Dash0 founder and chief executive Mirko Novakovic, who previously sold Instana to IBM, is building features such as AutoTune, where AI agents scan for inefficient code, generate improvement suggestions and prepare pull requests automatically. “Software is increasingly being written and operated by agents,” he said, and those agents need precise information about what code actually does.
The deal also brings Polar Signals’ Great Lakes storage engine, which will become the foundation of Dash0’s SignalStore infrastructure, replacing ClickHouse.
Dash0 says it now serves more than 750 customers, including Taco Bell and The Telegraph. The company raised $110 million in a Series B from Balderton, Accel, Cherry Ventures and others that pushed it past the $1 billion mark.
