Undisclosed · Series B · Agritech · Potsdam, Germany
Potsdam-based Stenon, which builds real-time soil intelligence for agribusinesses, has added Yara Growth Ventures in an undisclosed second close of its Series B. The company announced the investment on 12 October and said the capital will accelerate development of its soil nitrogen intelligence platform. Yara Growth Ventures is the corporate venture arm of crop-nutrition group Yara International.
The new investment extends the €18m first close that Stenon announced in July, led by Pymwymic with DeepTech & Climate Fonds as a new investor. Stenon has not disclosed the size of Yara's investment, so the €18m should not be presented as the amount of this second close.
Making soil data operational
Stenon's FarmLab combines proprietary sensors, artificial intelligence, agronomic models and cloud software to measure soil parameters directly in the field. The company sells to input retailers, machinery dealers, agricultural consultants and food producers, giving those businesses a way to generate nitrogen and soil data without waiting for a laboratory workflow.
That matters because plant-available nitrogen can vary within a field and over a growing season. More frequent measurements can give agronomists a better basis for deciding when and how much fertiliser to apply. In its July financing announcement, Stenon said customer use cases had produced 20-40% nitrogen-fertiliser savings and 2-8% yield increases across several crops; those are company-reported outcomes, not independently verified benchmarks.
Yara's role is strategically specific. Stenon contributes field sensing and a software layer, while Yara brings crop-nutrition and nitrogen-management expertise. That alignment can improve product development and agronomic validation, but the commercial value will depend on whether the partnership leads to repeatable deployments across crops and regions rather than remaining only a shareholder relationship.
Building beyond the handheld device
The July first close funded international expansion, stronger nitrogen and soil-organic-carbon capabilities, and work on a machine-integrated nutrient-intelligence system. Stenon said that next platform was still being prepared for a later-2026 announcement, so it should be treated as planned development rather than a launched product.
Founded in 2018 and headquartered in Potsdam, Stenon says FarmLab has received DLG and TÜV certifications and is used across multiple agricultural regions. The second close adds an industry investor with a direct interest in fertiliser efficiency, while leaving two things undisclosed: the new capital amount and any concrete commercial integration between Stenon and Yara.
