Dash0 buys Polar Signals for GPU observability

Dash0 acquired Polar Signals to bring continuous CPU, memory, and CUDA profiling into its agentic observability platform. In Dash0’s announcement, the company says the deal will connect line-of-code and GPU-kernel evidence to coding agents through MCP, while its platform already serves 750+ customers and had raised $110 million at a $1 billion valuation; financial terms were not disclosed. The operator signal is that agent-written software now needs production profiling, not just traces and metrics—an extension of the archive’s reliability analysis for business agents.
