Messium started with a simple observation: farmers deserved better nitrogen information than the industry was giving them. Here's how we built the answer.
George Marangos-Gilks and Vishal Soomaney Vijaykumar found Messium with a clear goal: build the world's most accurate crop nitrogen monitoring system using the new generation of hyperspectral satellites just becoming commercially available. The founding insight - that farmers needed precise answers, not more data - became the product philosophy.
Messium takes its name from Custos Messium - Latin for "the Harvest Keeper" - a constellation charted in 1775 and since faded from the star maps. We aim to be the Harvest Keepers of the 21st century, watching over crops from above.
Messium joins the European Space Agency's Business Incubation Centre, gaining access to ESA expertise, satellite data resources, and international networks. The systematic collection of physical crop samples alongside satellite passes begins - the foundation of the 30,000-sample training dataset.
Selected for the UK Space Agency's GEO Accelerator programme, Messium begins extensive farm trials across the UK and Europe. Working directly with farmers, the team refines its AI models against real field conditions - proving the accuracy of hyperspectral nitrogen estimation at commercial scale.
Messium closes a £1.4 million pre-seed round led by SuperSeed and Entrepreneur First. With 75 farms across the UK and Europe now using the platform, Messium's accuracy is proven in real-world conditions. Pilots begin in Australia, New Zealand, Canada and the US - validating the approach across different climates, crops and soil types.
A £3.3 million seed round - co-led by UKI2S (backed by the UK Space Agency) and Expansion Aerospace Ventures - funds the wider commercial rollout. The technology is proven. Now it's about reaching every farmer who needs it.
