$4m · Other round · Software · Berlin, Germany
OllyGarden, the Berlin-based observability software company, has raised $4m in venture funding to improve the quality of the logs, metrics and traces that engineering teams use to understand software systems. Tech.eu reports that Next Frontier Capital, Grand Ventures and ACTAI Ventures backed the round, with returning investor DIG Ventures and strategic investors Datadog, Grafana Labs and Dash0 also participating. The company told Tech Funding News that the capital will support engineering, go-to-market work and expanded access for open-source projects.
Telemetry quality moves into code review
OllyGarden is trying to solve an upstream problem. Observability platforms can store and query enormous volumes of telemetry, but noisy, incomplete or inconsistent instrumentation makes that data more expensive and less useful. The company’s Rose product reviews OpenTelemetry instrumentation inside a codebase, identifies gaps or low-value signals and prepares fixes as pull requests for engineers to approve.
The new Minimum Viable Instrumentation capability extends that workflow to repositories with little or no existing instrumentation. According to OllyGarden’s product documentation, Rose can establish an OpenTelemetry baseline that combines zero-code instrumentation with business context, again delivered through a reviewable pull request. That shifts telemetry quality from a periodic clean-up exercise into the development workflow, where teams can correct the source of a problem before it propagates across services and reaches a monitoring backend.
The commercial mechanism is cost and trust. Many observability products charge in ways linked to data volume, so preventing low-value signals can reduce storage and processing expenditure. OllyGarden also argues that cleaner telemetry gives engineers and operational AI agents more reliable context. Tech.eu reports the company’s claim that it has identified opportunities for customers to cut log volumes by as much as 85%; the article does not provide a sample size or independent methodology, so the figure is best read as a company-reported maximum.
Strategic investors validate the upstream problem
The participation of Datadog, Grafana Labs and Dash0 is notable because all three operate observability backends that receive telemetry. OllyGarden CEO Juraci Paixão Kröhling told Tech Funding News that those platforms can apply quality controls further downstream, while his company aims to fix the instrumentation that produced bad data in the first place. Their investment does not prove customer adoption, but it does support the view that telemetry quality is becoming a distinct layer of the stack.
OllyGarden launched in 2025 after a $1.6m pre-seed round. Tech Funding News reports that the latest financing takes total capital raised to about $5.6m and that the company has 10 employees. The next test is whether it can turn specialist OpenTelemetry expertise and strategic backing into repeatable enterprise adoption while keeping its vendor-neutral position clear.
