Descriptiontext

Rainmaker Technology Corporation is a privately held U.S. climate-technology company, founded in 2024 and headquartered in El Segundo, California, that commercializes next-generation cloud seeding to address water scarcity and drought across the American West. The company operates an integrated platform composed of three subsystems: a Target weather awareness software that uses AI-driven forecasting to identify optimal seeding windows, a Deliver drone-based delivery system that disperses silver iodide particles into target clouds as a lower-cost alternative to traditional manned-aircraft seeding, and a Validate advanced radar system that quantifies precipitation outcomes. In April 2026 the company announced what it characterized as the first-ever quantitative proof of manmade precipitation, reporting 82 unambiguous seeding signatures corresponding to over 143 million gallons of freshwater generated for Oregon and Utah.

Rainmaker sells cloud-seeding services primarily to state governments, water authorities, and ski resorts in drought-prone regions, with current operations concentrated in Utah, Idaho, Oregon, California, and Colorado. Its stated value proposition centers on moderating drought conditions, recharging aquifers, reducing wildfire risk, and supporting agriculture, municipal supply, and hydroelectric power. The company has also expanded into the ski-resort segment, deploying drone-based seeding to generate artificial snow at venues such as Winter Park Resort in Colorado. Revenue is generated through recurring service contracts with government and enterprise customers; pricing is not publicly disclosed.

The company has raised approximately $31.3M in disclosed funding, including a $6.3M seed round in May 2024 and a $25M Series A led by Lowercarbon Capital in May 2025, with notable participation from Peter Thiel, Garry Tan, and Balaji Srinivasan. Rainmaker pursues an active government-relations strategy, having spent $450,000 on federal lobbying and $100,000 on Capitol Metro advertising to influence weather-modification policy. It faces emerging regulatory headwinds, including Florida SB56 and Texas SB1154 proposals to restrict weather modification activity, and pushback from the Air Line Pilots Association against its FAA drone-fare proposal, which together represent material policy and execution risks.
