Rainmaker Secures $100 Million to Scale Cloud Seeding Operations

The round, led by investors including NOA VC, Upfront Ventures, and Lowercarbon Capital, will expand a workforce already comprised of atmospheric scientists and radar specialists. Rainmaker distinguishes itself by using weather-resistant drones to release silver iodide into storm clouds, a process now backed by radar validation systems that track precipitation in real-time. Earlier this year, the company recorded 82 distinct seeding signatures, proving the efficacy of its operations by generating millions of gallons of freshwater in targeted regions like Alaska and the American West.

CEO Augustus Doricko views this technology as essential for long-term climate adaptation, noting that the company intends to move beyond water production into broader weather modification, such as hail mitigation. By the upcoming winter season, Rainmaker expects to reach a price point for its water that undercuts traditional desalination and water-transfer alternatives. As reservoirs along the Colorado River remain at historic lows, the company is scaling its drone fleets across Utah, Idaho, Oregon, California, and Colorado, aiming to provide a scalable, cost-effective solution for agricultural and industrial water security.
