Helix Earth Raises $12M Seed to Reinvent HVAC with Liquid-Gas Chemistry

Helix Earth just pulled $12M out of the atmosphere and made HVAC feel like frontier tech again. Not bad for a company born out of space hardware and Houston humidity, where the air feels like it’s got a personality and a grudge. Dr. Rawand Rasheed and Brad Husick are not playing small-ball science projects here. Co-founder and CEO Dr. Rawand Rasheed took something built to keep astronauts alive and asked a better question: what happens when that same chemistry hits Earth’s most expensive, least questioned system… air conditioning? Co-founder and Chief Business Officer Brad Husick, with a track record that reads like a highlight reel of exits and scale, saw the commercial angle before most even realized there was a category forming.

So Helix Earth built a system that treats air less like a breeze and more like a balance sheet. Their liquid-gas chemistry platform slips into existing HVAC systems and separates temperature from moisture, which sounds simple until you realize how long the industry has been burning cash pretending those two things are the same problem.

Veriten led the $12M Seed 2 round, with Rua Ventures, Carnrite Ventures, Skywriter LLC, and Textbook Ventures stepping in like they’ve seen this movie before and know how it ends. Oversubscribed, of course. Capital tends to move quickly when physics meets profit in a $150B market that hasn’t had a real shakeup in decades.

The quiet part out loud is this: Helix Earth didn’t win because of a pitch deck. They won because they started with real science, anchored it in a massive, painfully inefficient market, and built something that bolts on instead of tearing out. No ego, just leverage. When you can walk into a building and cut energy use while improving air quality without asking for a full system overhaul, you’re not selling innovation, you’re selling inevitability.

And that’s the game within the game. The best founders aren’t chasing disruption headlines, they’re hunting for systems everyone depends on but nobody wants to rethink. Then they show up with something that doesn’t ask permission, it just makes the old way look expensive and tired. Helix Earth is doing exactly that. Quietly turning air into an asset class and making the rest of the market wonder how it missed something so obvious, sitting right there… in every breath.
