Rainmaker
Weather-technology company combining cloud-seeding drones, forecasting software, radar, and satellite analysis to enhance and validate precipitation.
The product
Stratus forecasting and mission software, Elijah high-altitude icing-capable UAVs with aerosol dispersal and sensors, and radar- and satellite-based precipitation validation systems.
The thesis
Rainmaker aims to make cloud seeding more precise, measurable, and scalable for water-stressed regions, agriculture, ecosystems, hydropower, and wildfire-risk reduction.
How it runs
Plans and executes field campaigns using proprietary aircraft and software, then estimates attributable precipitation with radar, satellite, atmospheric, and mission telemetry data while publishing validation methods.
How it earns
Inferred: project and seasonal service contracts with water districts, agricultural, municipal, industrial, energy, and government customers. Customer pricing and contract mix are not public.
Why it wins
Integrated targeting, drone delivery, and validation closes a long-standing measurement gap in cloud seeding; custom UAVs allow precise operation in icing conditions without crewed aircraft.
