Rainmaker Technology Corporation runs drone-based glaciogenic cloud seeding operations to increase precipitation for farms, watersheds, and municipal water supplies, primarily across the drought-stressed American West. The El Segundo, California company was founded by CEO Augustus Doricko , and its stack combines unmanned aircraft, radar, and atmospheric sensors to seed clouds and then measure how much rain or snow actually falls as a result. The pitch is turning cloud seeding from a difficult-to-measure service into water infrastructure priced by verified output.
The launch marks a $100M Series B, and the timing is tied to recent field results the company is using to argue the technique now works at scale. The round includes investments from NOA VC, Upfront Ventures, DCVC, Lowercarbon Capital and Dream Ventures. Earlier in the year, Rainmaker said it was the first company to unambiguously measure and validate the results of a cloud seeding operation , and a summer research campaign near Homer, Alaska reportedly produced 19 million gallons of precipitation in a three-hour window, on top of roughly 145 million verified gallons over an earlier four-month period.
For founders, investors, and operators watching climate and water infrastructure, the interesting question here is whether Rainmaker can convert those trial numbers into repeatable, contracted water delivery for utilities, farms, and basin authorities. The company says the capital will go toward hiring atmospheric scientists, aerosol chemists, and radar specialists, and toward standing up what it describes as a dedicated lab for weather modification and atmospheric science, positioning it against a field that has historically lived inside national labs and university departments rather than private industry.

Genuinely curious how you handle cross-border liability when a seeded cloud drifts over a neighboring state or country. Water rights lawyers are about to have a decade.

The tweet buries the lede at 'foremost lab for weather modification.' That's the headline, not the raise.

Any plans to open-source the atmospheric models or publish datasets? Would love to see academic labs able to poke at the methodology.

Bold to announce a rain company the same week half of X is arguing about chemtrails. Comms team earned their coffee today.

How small is the core ops team actually flying these missions? I keep imagining like 12 people and a Cessna.

How do you even A/B test a rainstorm? The counterfactual is the entire atmosphere.

Finally, a SaaS that literally makes it rain. VCs waited their whole careers for this pun.

That 40% number got cut off mid-tweet and I still don't know what happens by 2030. Cliffhanger launch copy is a choice.

Watch this be the last weather company launched before autonomous swarm drones handle the whole seeding loop end to end.
