Company Description

Rainmaker Technology Corporation is a next-generation cloud seeding company based in El Segundo, Calif. The company flies weather-resistant drones into winter storm clouds and releases a small amount of silver iodide, a particle that ice crystals form around. Those crystals grow heavy enough to fall as rain or snow. Rainmaker's own radar and validation systems then measures how much additional precipitation each operation produced, the step that has historically been missing from cloud seeding.
