Luxembourg and US-based Hydrosat, a provider of thermal infrared satellite data and AI-powered analytics, today announced the close of €51 million ($60 million) in Series B to accelerate growth across commercial, civil government, and defense markets.
The round was led by Hartree Partners, Subutai Capital Partners, and Space 4 Earth, with new investment from Truffle Capital. The round includes follow-on investment from the Luxembourg Future Fund, OTB Ventures, Blue Bear Capital, Statkraft Ventures, Cultivation Capital, and Santa Barbara Venture Partners. The total reflects the core Series B financing as well as additional equity investments.
“We’re seeing remarkable momentum behind Hydrosat’s mission,” says Pieter Fossel, CEO and co-founder of Hydrosat. “This new funding underscores the company’s sustained growth and positions us to meet the increasing demand for intelligent solutions to some of society’s most complex challenges in national security and natural resources.”
Hydrosat’s Series B sits within a wider flow of capital into Earth observation, satellite infrastructure and AI-driven geospatial analytics across Europe in 2025, as tracked by EU-Startups.
Recent examples include Italy-based Titan4, which raised €4 million to scale its AI-enabled Earth intelligence platform combining satellite data and ground sensors, and Germany’s Marble Imaging, which secured €5.3 million to advance a very-high-resolution Earth observation constellation ahead of its first satellite launch.
In France, Infinite Orbits closed a €40 million round to expand satellite inspection and servicing capabilities, while Spain’s Kreios Space raised €8 million to develop very-low-Earth-orbit propulsion systems aimed at improving observation performance. Germany has also seen larger growth rounds, notably Reflex Aerospace with a €50 million Series A to build high-performance satellite platforms for ISR use cases, and Spain-based Xoople, which emerged from stealth with €115 million to deliver AI-ready Earth data streams.
Taken together, these deals represent well over €220 million flowing into adjacent SpaceTech and Earth intelligence segments, indicating sustained investor focus on both upstream satellite capabilities and downstream analytics.
Against this backdrop, Hydrosat’s latest financing places it among the larger growth rounds in the sector, reflecting continued demand for high-frequency, decision-grade thermal data across agriculture, water management, insurance and defense.
“Hydrosat’s data is rapidly becoming essential infrastructure for managing water resources. By providing continuous, regional or field level, insights into irrigation patterns and best practices the company gives governments, agribusinesses, and communities the clarity they need to build resilience,” adds George Potts, Head of Hartree Partners’ Technology Investment Business.
Founded in 2017, Hydrosat leverages thermal satellite data and AI to address critical global challenges in food production, security, and natural resource management.
Hydrosat currently monitors millions of acres for customers such as NOAA, NRO, Bayer, SupPlant, and Nutradrip, who use the company’s high-resolution, timely satellite thermal imagery to deliver advanced analytics that convey precise crop yield forecasts and improved irrigation tools to agricultural, commercial, and public sector customers.
Through global temperature insights, the company provides critical data to monitor water use, optimise irrigation, improve water productivity, and detect early indicators of vegetation stress or drought.
These capabilities are increasingly vital as water scarcity reshapes agricultural and economic systems worldwide.
With two thermal infrared satellites in orbit, Hydrosat’s collection capacity now exceeds 10 million square kilometers of imagery per day. Advanced AI and machine learning models further enhance this data.
Beyond commercial and civil government use, Hydrosat’s imagery also supports defense and intelligence organisations that rely on temperature-based signals to monitor activity and change on the ground.
“We’re entering a new era where space-based intelligence is no longer optional for insurers – it is becoming fundamental infrastructure. Hydrosat exemplifies the convergence of SpaceTech, DefenseTech, AgriTech, and InsurTech, with its thermal constellation delivering the high-frequency data needed to accurately price agricultural and water risk and enable parametric insurance.
“That’s why Hydrosat has invited Truffle Capital to this round for its added value to accelerate adoption across insurance and financial services,” shares Bozena Adamczyk, Partner at Truffle Capital.
The funding will further expand Hydrosat’s global footprint – with deepened presence in key regions such as Central Asia, MENA, India, and Latin America – and support the next phase of constellation development and product evolution.
The company will scale its thermal satellite fleet, with advanced next-generation imaging systems, and expand its Water & Crop management solutions.
