Karman+ Secures $20M Funding for Autonomous Asteroid-Mining Spacecraft Development

Investors are constantly on the hunt for the next big thing in technology, often venturing into uncharted territories. One such frontier is space, and a startup called Karman+ is making waves with its ambitious plan to mine asteroids. The company has just secured $20 million in a seed round, which it will use to advance its hardware and software development.

Karman+'s goal is nothing short of extraordinary. They aim to build autonomous spacecraft capable of traveling to asteroids, which could be millions of miles away, and mine them for materials. Specifically, they plan to extract water from the asteroid's surface material, known as regolith, and then return to Earth's orbit. This water would be used to refuel space tugs and extend the life of aging satellites.

Looking further ahead, Karman+ sees potential in extracting rare metals and other materials from asteroids, contributing to a broader space manufacturing ecosystem that could complement or even replace some of Earth's industrial processes.

While this sounds like something straight out of science fiction—indeed, asteroid mining was a key theme in the 2013 Nebula Award-winning novel "2312"—Karman+ believes it's closer to reality than one might think. Thanks to advances in autonomous technology, space exploration, and their own innovative use of off-the-shelf components, they're confident in their approach.

Karman+ aims to run missions for $10 million or less, a stark contrast to the $1 billion typically spent on asteroid exploration missions. They also see a potential market for refueling services worth billions of dollars annually. The company is targeting its first launch in 2027.

Based in Denver, Colorado, Karman+ has Dutch roots through its co-founder and CEO, Teun van den Dries. This European connection has helped them secure funding from investors like London-based Plural, Antwerp-based Hummingbird, Paris-founded HCVC, and others, including Lookout co-founder Kevin Mahaffey and unnamed angels.

The startup's name, Karman+, is inspired by the Karman Line, marking the boundary between Earth's atmosphere and space. This is a fitting metaphor for the company's bold vision. Van den Dries, along with co-founder Daynan Crull, brings a wealth of experience. The two previously worked together at GeoPhy, a real estate data startup that was acquired for $290 million in 2022. After the acquisition, van den Dries, a self-described "science fiction nerd" with a background in aerospace engineering, decided to pivot towards something he believed could have a more significant impact.

"Two years ago, I was at an inflection point," van den Dries recalled. "I could continue optimizing SaaS businesses, or I could focus on something that could truly change the game." With Crull, a data scientist now serving as Karman+'s mission architect, they set their sights on space.

Van den Dries noted that the space market was under-invested, especially compared to other areas like fusion, which has attracted over $5 billion in funding. He believes asteroid mining offers a unique opportunity for cost efficiency, given that asteroids are in the right orbital plane, making them easier and cheaper to access than resources from the moon or Earth.

"The beauty of asteroids is that they're at the right plane," he explained. "It's the easiest, cheapest, fastest place to get resources. If you can provide materials at attractive prices, you can build a flywheel that enables all sorts of things we can't currently do."

However, Karman+ isn't alone in this venture. Another startup, AstroForge, is also pursuing asteroid mining. Yet, the challenges are immense. Karman+'s spacecraft is still in development and yet to be tested. While they aim to keep costs down to around $10 million, past asteroid missions by NASA and a Japanese team have cost over $1 billion each.

Moreover, asteroids are moving targets, orbiting the sun at vast distances from Earth. Refueling satellites, a key part of Karman+'s plan, is also a complex issue, as not all satellites use the same fuel types. And, of course, Karman+ will need to raise more funds as they approach their launch date.

Despite these hurdles, Karman+'s investors remain cautiously optimistic. Sten Tamkivi, a partner at Plural, admitted to initial skepticism but was impressed by the founders' realistic approach.

"I went into this conversation very skeptically, and one thing I found out was that the founders have approached this very skeptically, too," Tamkivi said. He believes their cautious approach will help keep the team grounded as they move forward, giving him confidence in their far-reaching vision.

"I think you see way more YOLO in the software world," Tamkivi added. "People assume everything has been built, so you just plow through and figure out the problems later. The space guys, they actually make detailed plans. There's a lot of stuff you can review, dig in, and get third-party opinions."
