Washington and Luxembourg-based firm Hydrosat, a provider of thermal infrared satellite data and AI-powered analytics, has secured $60 million in new funding to accelerate growth across commercial, government, and defense markets. The round was led by Hartree Partners, Subutai Capital Partners, and Space 4 Earth.
- Hydrosat was established in 2017 by Pieter Fossel, Royce Dalby, Yunjin Kim, and Jakob van Zyl, with the aim of using thermal imagery to measure how much water crops and land surfaces are actually using. The company develops and operates thermal-infrared satellites that detect surface temperatures, which are reliable indicators of plant stress, soil moisture, and irrigation activity.
- These satellites collect large volumes of data each day, which Hydrosat processes using its own algorithms and machine-learning models to translate temperature patterns into estimates of water use, crop health, and drought risk.
- The resulting datasets are delivered to governments, agribusinesses, insurers, and research organizations through software platforms and data feeds, allowing them to monitor irrigation, forecast yields, manage water allocations, and track changes on the ground at field, regional, and national scales.
Details of the deal
- The $60 million Series B round was led by Hartree Partners, Subutai Capital Partners, and Space 4 Earth, with new investment from Truffle Capital and follow-on support from the Luxembourg Future Fund, OTB Ventures, Blue Bear Capital, Statkraft Ventures, Cultivation Capital, and Santa Barbara Venture Partners.
- Hydrosat plans to direct the new funding toward launching additional satellites, improving its thermal sensors and processing systems, and extending its operations into regions where water and agricultural risks are increasing.
- The company will also put resources into developing new analytical tools that convert raw imagery into usable information for public agencies, farms, insurers, and security organizations, enabling broader and more consistent coverage of land, crops, and water conditions worldwide.
“We’re seeing remarkable momentum behind Hydrosat’s mission. 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," claims Pieter Fossel, CEO of Hydrosat.
