AirJoule Technologies (AIRJ) Initiating Coverage

Pre-revenue CleanTech company addressing a pressing challenge

Since launch, our goal with Sophon Microcap Atlas has been to build the definitive research hub for underfollowed sub-$500M companies. Each month we’re adding deep-dive coverage, proprietary scoring frameworks, and differentiated insights you won’t find anywhere else. With every report, the value of the platform compounds — but so does the subscription price.

We’ve structured it this way deliberately: to reward early adopters who believe in what we’re building. Subscribers who joined at launch are still paying their original rate, and they’ll keep that price for life. By contrast, new readers coming in today are already paying more than they did six months ago.

That’s by design. We’re investing heavily in research, and we want to keep the economics aligned with our most loyal readers.

When you join Sophon Microcap Atlas, your subscription price is locked in for life. We raise rates by $15 every two months to reflect the growing value of our research library, but early subscribers keep their lower rate forever. On November 1, the price rises to $60/month or $540/year — lock in now at $45/month or $400/year and you’ll still be paying that rate years from now, even when the service is worth thousands.

AirJoule is a platform company with modular, scalable technology capable of producing high-purity water from air while converting wasted heat into a valuable resource. Its pre-commercial, capital-efficient model, strong IP portfolio, and strategic partnerships position it to address a $450B market. If energy efficiency, reliability, and scalability deliver as projected, AirJoule could disrupt industrial water sourcing and HVAC energy consumption, creating a durable, high-impact business in a market under growing global stress.

While we’re open to building positions in pre-revenue companies (as we did with Ucore Rare Metals) we are hesitant with AirJoule due to a lack of understanding regarding its technology, as well as the market opportunity. We’re keeping this in a pile to closely monitor.

AirJoule Technologies is addressing one of the world’s most pressing challenges: the lack of clean water and the high energy costs to produce it. The company’s mission is straightforward: pull water from the air using technology that also leverages energy that would otherwise go to waste. Unlike companies that sell a single machine, AirJoule is building a platform of solutions that can supply water to industrial facilities, military operations, and governments in arid regions. Its long-term vision is to become the leading technology ecosystem for water and energy.

At its core, AirJoule’s system works like a sponge for water in the air, but far smarter. Ambient air passes through heat exchangers coated with a metal-organic framework (MOF), a material engineered to attract water molecules and hold them in tiny pores. Once the sorbent is full, the chamber is sealed and a light vacuum is applied. Heat from the process or low-grade waste heat from industrial sources releases the trapped water, which is then condensed into pure, distilled, PFAS-free water. Two chambers operate alternately, with one capturing water while the other releases it, allowing heat to be reused, which makes the system highly energy-efficient. The air leaving the system is drier, which can also reduce energy needs in HVAC systems.
