Overview

Rainmaker is a cloud seeding company based in El Segundo, California, that operates an integrated system of weather radar, unmanned aircraft, and monitoring software to generate rainfall in water-stressed regions. Its platform identifies optimal seeding conditions, deploys drones to disperse seeding agents into clouds, and uses radar to validate results, modernizing a decades-old atmospheric science practice. What sets Rainmaker apart is its embedded research organization, which prioritizes transparency and scientific rigor, and its focus on American-made hardware for agriculture, drought relief, and ecosystem restoration. The goal is to end water scarcity by making precipitation enhancement more precise, measurable, and widely accessible.
