Stenon Raises €18 Million to Scale Real-Time Soil Intelligence
Stenon, a Potsdam-based agricultural technology company that develops real-time soil-data infrastructure for agribusinesses, has closed an €18 million Series B round to scale its real-time soil data offering. The company plans to use the capital to accelerate product development and expand commercial activity, particularly around plant-available nitrogen management and soil organic carbon measurement. The financing arrives as farms face renewed pressure to improve input efficiency while preserving productivity and soil performance in a global market affected by higher input volatility.
A Backing for Growth
Impact investor Pymwymic led the financing, while DeepTech & Climate Fonds joined as a new backer. Returning investors Atlantic, Oyster Bay, Founders Fund, TIME Ventures and Bernd Hoffmann also participated, giving the company a mix of agriculture, impact and deep-tech capital. Stenon said the expanded shareholder base will support international growth and further investment in its sensor technology, agronomic models and software platform as it brings hardware and software to larger agricultural operations.
Nitrogen Management in Focus
At the center of its strategy is nitrogen, an input whose cost and availability can sharply influence a farm's economics. Stenon cited European Commission data showing that EU nitrogen fertilizer prices in April 2026 were 71 percent above their 2024 average, underscoring why farmers and agribusinesses are looking for more precise application decisions. Rather than replace fertilizer, the company's approach is designed to help users determine more accurately how much to apply and when, using localized recommendations grounded in field conditions.
Building Real-Time Soil Data
Stenon’s FarmLab platform combines proprietary optical and electrical sensors, artificial intelligence, agronomic models and cloud software to analyze soil conditions directly in the field. Its system measures plant-available nitrogen, along with SOC and other parameters, so users can generate current data rather than wait for conventional laboratory testing. The company sells through and supports input retailers, agricultural groups, machinery dealers, consultants and food producers across several million customer acres.
Commercial Use Cases
Stenon says customer use cases across crops including corn, beans, cotton, sugarcane, coffee, grains and vegetables have produced nitrogen fertilizer savings of 20 to 40 percent alongside yield gains of 2 to 8 percent. These results are company-reported, rather than independently verified performance data, and reflect the commercial argument behind its data-led soil management model. The business has already deployed its technology in South America, Central Asia and Europe, where it adapts models and recommendations to local crops, soils and practices.
Expansion and Product Development
The new funding will expand commercial and service operations in Brazil, a core market, and the wider South American market, Central Asia, and selected European countries where Stenon already operates. It will also support regional calibration, product localization and customer support, while advancing FarmLab’s nitrogen and SOC capabilities. Later in 2026, Stenon expects to unveil a machine-integrated, real-time nutrient intelligence platform that builds on the handheld field-sensing system it has developed to date.
With fertilizer volatility putting farm margins under strain, Stenon is positioning its platform as an operational tool rather than a purely analytical service. Its goal is to move soil intelligence closer to the point at which nutrient decisions are made, creating a more continuous data flow for large-scale agriculture. The Series B gives the company additional capital to pursue that transition while extending its reach across its existing footprint in markets where nutrient efficiency has direct financial and environmental importance.
