About Rainmaker

Rainmaker (Rainmaker Technology Corporation) is an El Segundo, California climate-technology company that builds cloud-seeding systems—weather software, radar and unmanned aircraft—to increase precipitation and supply freshwater for farms, ecosystems, communities and industry. Led by Augustus Doricko, Rainmaker combines atmospheric science with field deployments; the company says it has verified large volumes of seeded precipitation in research programmes, including work near Homer, Alaska, and aims to lower cost per acre-foot of incremental water versus alternatives such as desalination in basins like the Colorado River. In September 2026 Rainmaker raised $100 million in Series B funding from investors including NOA VC, Upfront Ventures, DCVC, Lowercarbon Capital and Dream Ventures to scale research hiring, sensing and autonomous seeding operations toward what it calls a “Weather Prime” capability.
