Mankind has always been at the mercy of the weather. No longer. Rainmaker is the first company in history to routinely, unambiguously, modify the weather. Last quarter, we produced >143MM gallons of unambiguously man-made precipitation. Here’s how we do it 🧵

A couple years ago the Ulysses team wheeled a tub of water and their first robot into our SF office. They said they would give humanity the tools to unlock the ocean frontier. They’re making good on that promise. Grateful to have backed them since the beginning 🦈

Ulysses has raised $46M led by a16z American Dynamism. We are building The Ocean Company. The ocean is 71% of the planet. But it is less explored than Mars, and full of secrets, waiting to be told. It is the backbone of global defense. Home to the critical infrastructure that powers our world. And the key to the health of our planet. This frontier needs technology to protect and steward it. We are building it. And we need more builders Join us and explore the Great Blue Frontier: theoceancompany.com/careers

We’re going to save the Great Salt Lake and Colorado River from drought by making it rain and snow Thanks for coming by @GadiNBC !

@eastdakota @RainmakerCorp @Deer_Valley ???

@RainmakerCorp @Deer_Valley Uhhhh… we didn’t lack precipitation this year, we had too warm of temperatures. You may have been able to make it rain more, but that’s just would have melted the snow even faster. 🤡

It's painful to see @Deer_Valley closing early this year. Hundreds of jobs, thousands of tourists & millions of dollars into Utah's economy lost due to snow drought. We can help.

A group of sharks is called a shiver. Which is exactly what you will experience if you ever see a group of these racing toward you. @ulyssesinc

THE OCEAN IS CALLING Since coming out of stealth one year ago, we haven’t shared many updates about @ulyssesinc. Our Communications & Public Relations Division profoundly apologizes for this. But today, we break our silence and make five major announcements: - MAKO: We are sharing details on Mako, our first autonomous underwater vehicle, the “Model T for the ocean”. - LEVIATHAN: We are announcing Leviathan, our first autonomous surface vehicle, a mothership for other drones and maritime domain awareness platform. - MAJOR WINS: We are announcing our major accomplishments in 2025 - new customers, lots of missions, and manufacturing and plans for 2026 and beyond. - NEW WEBSITE & BRAND: We are launching a new website and an updated brand. - RODEO: A gift for our friends in San Francisco. (Read to the end.) Please watch this video below & read on for more details.

The world needs more water Our farms, industries, environment, and homes will live and die by access to water I couldn’t be more grateful to all Rainmakers and our partners as we produce water for the Great Salt Lake with next-gen cloud seeding 1/2

today ulysses ran a complex mission for a customer with: - a heavy robotic payload (that we designed & built), - strong currents - and very poor water clarity we did this with FULL autonomy and it performed better than any human operator could underwater intelligent autonomous robots are here and working

I’m hiring for two major roles on my team at Ulysses. There has not been a better time to join Ulysses. In the last few months, revenue & pipeline have gone vertical, and we've made significant technological breakthroughs that will forever change how subsea work is done. It's been the most successful period in our company's history, and we are just getting started. We will be announcing some of these breakthroughs soon. Stay tuned. The jobs: 1. GM, Commercial: Your job is to stand up and lead our commercial business unit. Take our early contracts and scale them to build a machine that reshapes how critical telecoms and energy infrastructure is inspected and repaired. 2. Director of Marketing and Brand. Your job is to make Ulysses impossible to ignore. World-build. Make Ulysses "the Ocean Company". Take the air out of the room. High taste. No slop. Tell the world what Ulysses does. Quit your boring desk job. The ocean is calling. Full job descriptions are @ ulysses.inc/jobs

btw this vehicle already 2 generations old… we’re moving at flank speed here @ulyssesinc 🌊🦈

Today, @DOGECommittee held a closed-door hearing on weather modification. As the leading cloud seeding company in the US, Rainmaker would have loved to participate. Maybe next time! In the interim, some thoughts on the future of water and weather in America:

@willob We have culture everywhere

Just saw a coffee truck on the side of the road in rural Ireland selling an açaí bowl and an oat milk flat white to a farmer Sell everything

@CalvinCupini @AndreasenJack How do you think this gets solved?

@AndreasenJack Genuinely, this should be shared as one of the reasons for the failure of the market. The science gets blamed for energy balance / cost etc, but the middle layers were just chaos.

This is carbon removal

Announcing @RainmakerCorp and @atmo_ai 's strategic alliance to transform weather modification with AI-powered precision cloud seeding. We're combining our radar-driven, drone-based cloud seeding with their ultra-precise AI meteorology to fight drought worldwide. 🧵

@lymanstoneky @cremieuxrecueil Why does it include 5 of the main ski resorts in Colorado?

This is the best attempt I've seen yet to identify what lands might plausibly be nominatable under Lee's proposed federal land sale. As you can see it's a very small total amount of land. I'm sure there are still some errors (Montana is excluded from the bill), but this seems in principle about right.

Become a Rainmaker Make it rain, and snow, and end droughts

@ADoricko @willob Wrong.

The obvious takeaway from this post is that @willob must move to Gundo

I wrote a bit on how we @lowercarbon think about those who push forward the state of the art, and why we believe so deeply in @RainmakerCorp. Come hell or low water, they're serving desperate customers in far corners of the earth to end water scarcity. lowercarbon.com/2025/05/07/rai…

Announcing Rainmaker’s $25M Series A lead by Lowercarbon Capital, with participation from Naval Ravikant, Acequia Capital, Drover Ventures, Sovereigns Cap and others We have begun nextgen precipitation enhancement operations across the US to make rain, snow and green deserts🧵
