OllyGarden raises $4M to fix telemetry before it reaches monitoring systems

Why it matters

OllyGarden is betting that AI-generated code makes instrumentation quality part of software development as well as observability. Its new funding supports tools designed to improve telemetry at the source, before it reaches monitoring systems.

OllyGarden raised $4 million in venture funding, Tech.eu reported on October 9th. Founder Juraci Paixao Kroehling is taking OllyGarden's telemetry-quality tools further upstream, into the code where instrumentation is added. The round also accompanied a new capability for Rose, OllyGarden's AI OpenTelemetry Engineer: it can now identify where instrumentation is missing and recommend a baseline, as well as review what is already in place.

AI coding tools can increase the volume of telemetry, while missing or noisy signals leave engineers without useful context. OllyGarden aims to improve data before it reaches an observability backend, reducing excess data that teams would otherwise have to sort through or pay to store.

The founder's OpenTelemetry track record

Kroehling came to OllyGarden with years of work inside the open-source observability infrastructure the startup is built around. In his 2021 OpenTelemetry Governance Committee candidate profile, he said he had maintained Jaeger since 2018 and contributed to OpenTelemetry since 2019. He listed creating and maintaining the OpenTelemetry Operator since 2019 and Collector Builder since 2021, and serving as an approver for Collector Contrib and Collector core since 2020. He also said he had worked at Red Hat before recently joining Grafana Labs to help build an OpenTelemetry-focused team. These details come from Kroehling's submitted profile; the profile does not independently document his employment or contribution history.

Kroehling founded OllyGarden with Yuri Oliveira Sa, an SRE and OpenTelemetry specialist, according to the founders' OllyGarden introduction. Their thesis was already visible in that 2025 launch post: automated instrumentation can collect far more information than teams need, raising costs and obscuring useful signals. OllyGarden aims to address telemetry quality where it originates, through better instrumentation practices and code changes.

The funding round was backed by Next Frontier Capital, Grand Ventures and ACTAI Ventures, with existing investor DIG Ventures also participating. Datadog, Grafana Labs and Dash0 made additional strategic investments, Tech.eu reported. The report does not identify a lead investor or clarify whether those strategic investments are included in the $4 million figure. It also gives no valuation.

From reviewing code to filling the gaps

Rose previously analyzed existing instrumentation and suggested improvements. Minimum Viable Instrumentation, or MVI, expands Rose's role: when a repository lacks instrumentation, Rose can guide a baseline instead of only flagging problems in existing telemetry. OllyGarden says the aim is consistent practices across teams, repositories and pull requests without producing unnecessary data.

Rose's product materials describe source-code review and fixes delivered as pull requests, leaving a human team to review and merge changes. MVI extends that approach to a service or repository that has little instrumentation to assess in the first place.

Kroehling told Tech.eu that the growing use of AI-generated code has contributed to rising telemetry volumes, making it harder to find critical information. The product is designed to give coding agents and engineers a more deliberate baseline, so each new service doesn't add data without a shared standard.

OllyGarden says businesses it has worked with identified opportunities to reduce log volumes by as much as 85% over the past year. That is a company-reported maximum, not a measure of typical savings: the report supplies no sample size or methodology. OllyGarden also says it works with businesses in retail, financial services and enterprise software, but the funding report names no customers.

In OllyGarden's introduction, Kroehling argued against the assumption that collecting more signals automatically improves observability. He told Tech.eu: "More instrumentation is not better instrumentation. It's about surfacing only the information and data that's useful and actionable: no more, no less."

The $4 million round accompanies Rose's expansion from remediation into setting a baseline. Datadog, Grafana Labs and Dash0 are strategic investors, but their investments do not show that they are customers or that the product has won broad adoption. The commercial test is whether engineering teams will make instrumentation quality a continuing part of code review, and whether OllyGarden can show that cleaner telemetry improves both costs and the usefulness of incident data.
