## About

Based in El Segundo, US, and founded in 2023 by Augustus Doricko (CEO), Rainmaker Technology Corporation is an environmental company that provides artificial rain services through its cloud-seeding technology for farms, watersheds, and ecosystems. In September 2026, Rainmaker Technology Corporation raised USD 100 million of series B funding from Noa, Upfront, DCVC, Lowercarbon Capital, Dream Ventures. Rainmaker Technology Corporation provides an integrated cloud-seeding system covering targeting, delivery and validation. Its proprietary Stratus forecasting and nowcasting platform analyzes real-time weather data to identify seeding opportunities. Purpose-built Elijah UAVs use integrated sensors and aerosol-dispersal systems to deliver seeding agents into suitable clouds. Radar and satellite monitoring then measure mission results using quantitative precipitation estimation. Applications include snowpack enhancement, aquifer recharge, reservoir replenishment, agricultural water supply, hydropower stabilization and ecosystem restoration. The September 2026 investment allows the company to expand its atmospheric research organization, support researchers at national laboratories and cultivate weather-modification research at U.S. universities.
