Observability startup Dash0 announced this week that it acquired Berlin-based continuous profiling specialist Polar Signals. The deal adds continuous profiling to SignalStore, Dash0’s OpenTelemetry-native data platform. Continuous profiling has been part of the developer toolbox for years and provides teams with an ongoing view of where running applications spend CPU time, allocate memory and consume other resources. Many observability platforms now include some form of it. Polar Signals offers a less common capability: continuous profiling of Nvidia CUDA workloads in production. Dash0 said the technology can profile both AI training and inference workloads, with visibility down to individual GPU kernels, to help monitor resource consumption and pinpoint where performance problems are occurring. Dash0 will integrate Polar Signals’ profiling data into SignalStore and feed it into Agent0, its AI agent for production operations. Agent0 can already correlate telemetry with source code and prepare pull requests for fixes. Profiling adds another source of runtime evidence to those investigations, which Agent0 can use when deciding what changes to propose. Dash0 will also let external coding agents access that profiling data through its MCP server, giving them runtime context for suggesting changes. The company is also developing AutoTune, an Agent0 capability that will analyze profiling data on a schedule and look for opportunities to improve CPU and memory use. When it identifies an optimization, AutoTune is designed to open a pull request with the proposed change and the …
