Dash0 acquires Polar Signals to power self-optimising software
What's the deal? Observability startup Dash0 has acquired Berlin-based Polar Signals, the companies announced in August 2026. The deal brings Polar Signals' continuous profiling technology — and its engineering team — into Dash0's platform.
What do they do? Dash0, founded in 2023, builds an observability platform that lets software teams monitor IT systems, find errors and analyse application performance. Polar Signals specialises in continuous profiling, which shows developers exactly where their code consumes computing power and memory.
What's the endgame? Dash0 wants to embed profiling data directly into agentic features, where AI systems not only write software but monitor and improve it in production. A new function called “AutoTune” is meant to continuously scan for inefficient code, then prepare improvement suggestions and pull requests on its own.
Why now? “Software is increasingly written and operated by agents,” said founder and chief executive officer Mirko NovakovicDealroom has a profile for this one.

What else? The deal is more than a product buy. Dash0 also gains Polar Signals' storage engine “Great Lakes”, built for large volumes of profiling data. It will form the basis of Dash0's SignalStore, replacing ClickHouse as data volumes grow.

His latest bet reflects a broader industry shift: as AI agents take over more of the coding and operations pipeline, the tooling that feeds them detailed, real-time performance data is becoming strategic infrastructure.
