OllyGarden's $4 million bet moves telemetry fixes into the pull request
OllyGarden raised $4 million as its Rose agent moves upstream to propose baseline instrumentation in code. Founder Juraci Paixao Kroehling says AI-written code is pushing telemetry volume up, so the fix belongs in code before teams pay to store it.
The Engineer · Build desk

Review teams must review and merge each Rose pull request. Engineers and coding agents get a shared baseline. Repos without instrumentation can get a guided baseline. Teams paying for storage face less excess data. Strategic investors: Datadog, Grafana Labs and Dash0.

What happened
- Rose works on source code and delivers its fixes as pull requests, leaving a human team to review and merge each change.
- Kroehling's 2021 OpenTelemetry Governance Committee profile says he maintained Jaeger from 2018, created the OpenTelemetry Operator in 2019 and approved Collector changes from 2020.
- Datadog, Grafana Labs and Dash0 joined the round as strategic investors, Tech.eu reported.
Why it matters
- cost Any cut in storage spend is paid for first in reviewer time, because each baseline or fix is a pull request someone has to read and merge.
- constraint A shared baseline limits how much telemetry each new AI-written service can add before anyone has agreed on a standard for it.
- decision Telemetry quality becomes a development-team responsibility as well as an observability one, so engineering leads have to decide where the standard lives and who approves changes to it.
Rose, OllyGarden's AI OpenTelemetry Engineer, works on source code and ships its changes as pull requests for a human to merge [8][11]. Before this release, Rose analyzed existing instrumentation and suggested improvements [9]. Minimum Viable Instrumentation covers the repository with nothing to analyze. When instrumentation is missing, Rose can now guide a baseline instead of only flagging problems in what exists [10]. OllyGarden says the goal is consistent practice across teams, repositories and pull requests without producing unnecessary data [12].
The case for moving upstream is volume. According to the runtimewire report, AI coding tools can increase the amount of telemetry, while missing or noisy signals still leave engineers without useful context [16]. Kroehling told Tech.eu that growing use of AI-generated code has contributed to rising telemetry volumes and made critical information harder to find [15]. MVI is meant to give coding agents and engineers a deliberate baseline, so each new service does not add data without a shared standard [13]. I think the pull request is the right delivery format for that. A baseline written by an agent goes through the same human review as the code beside it [11], so a team can reject one that drops a signal it relies on.
The argument predates the AI-code pitch. The founders' 2025 launch post said automated instrumentation can gather much more data than teams actually need, driving up costs and burying the signals that are useful [18]. Kroehling 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." [17]
The 85% claim needs a careful read [19]. Identified is the verb to read twice. It describes findings in those codebases over the past year. The figure is a company-reported maximum, and the report does not include a sample size or a methodology [20]. At that ceiling a team would keep 15% of its log volume [23]. For the number to transfer, another team's logs would need the same share of excess as OllyGarden's best case, and its reviewers would need to merge the changes. The company says it works with businesses in retail, financial services and enterprise software [21].
Kroehling's OpenTelemetry history comes from his own 2021 governance committee candidate profile, and those details are self-reported [3]. The same profile says he worked at Red Hat before joining Grafana Labs to help build an OpenTelemetry-focused team [4]. He co-founded OllyGarden with Yuri Oliveira Sa, an SRE and OpenTelemetry specialist [5].
Next Frontier Capital, Grand Ventures and ACTAI Ventures backed the $4 million round, and existing investor DIG Ventures participated, Tech.eu reported [1][6]. The three strategic investors back a product whose stated aim is less excess data for teams to sort through or pay to store [7][14].
What to watch
- OllyGarden publishing the sample size and methodology behind the 85% figure, or a named customer reporting reductions after merging Rose's changes.
- A public description of what an MVI baseline contains for a given service, and whether coding agents consume it before they write code.
- Whether strategic investors Datadog, Grafana Labs and Dash0 ship any integration with Rose.
