Rainmaker is building water infrastructure for a drier planet. The company uses drones to disperse silver iodide into clouds, triggering precipitation on demand. The technology is cloud seeding, but at industrial scale and commercial economics for the first time.
Founded by Augustus Doricko, Rainmaker operates in a market where water scarcity has shifted from environmental concern to capital expenditure. Utilities, agriculture, and state governments are buyers.
Cloud seeding is now moving from government pilot to private water utility. The regulatory pathway is opening across drought-impacted states, and Rainmaker is the leading venture-backed operator at industrial scale. Growth Circle members have $6M of direct allocation.

DISCLOSURE
Everything you see here is for informational and educational purposes only—this isn’t investment advice, and it’s definitely not a solicitation to buy or sell any security. Every investment involves risk, and while we do our best to present strong opportunities, past performance never guarantees future results. Any return projections are based on what we know and believe today, and things can change. Always talk with your CPA, attorney, or financial advisor before making any investment decision.
And here's the part we’re proud of—alignment: I personally invest in the same deals we bring to Growth Circle. I'm not just showing you what’s out there; I’m putting skin in the game right alongside you. In some cases, I may have ownership or business relationships with the teams behind these deals, and that means I might earn a share of the upside when you invest. I believe in being transparent about that. As always, you’re in control. Do your own diligence, ask the hard questions, and invest when it makes sense for you.
