K2 Space, a manufacturer of large satellites for demanding applications such as high-bandwidth communications and defense operations, has completed a $500 million fundraising round that it will disclose on Thursday.
The startup's valuation stands at $6.8 billion following the investment. Kleiner Perkins and Iconiq jointly led the Series D round. Additional backers included Lightspeed Venture Partners, CapitalG from Alphabet Inc., Altimeter Capital Management, and other investors.
This funding reflects a broader wave of capital flowing into the space sector. Over the past few years, investors have committed billions to space startups, wagering that cheaper launch costs and rising demand will spark a new growth era.
K2 Space deployed its first satellite about four months ago. Its technology is engineered for rapid, low-cost production - each satellite runs roughly $15 million, in contrast to conventional models that can exceed hundreds of millions. The initial satellite generates 20 kilowatts of power, comparable to the largest commercial spacecraft from Airbus SE and Boeing Co.

Now that its first satellite is in orbit, the company is prioritizing volume manufacturing. CEO Karan Kunjur said in an interview, "Our customers are like, 'Okay, you've proven you can do this. We absolutely need it. Your technology is clearly differentiated. Now how quickly can you deliver this for our mission needs?'"
K2 Space holds over $1 billion in signed contracts, roughly split between government clients such as the US Space Force and commercial partners, according to Kunjur.
That sum includes a contract tied to the Golden Dome for America initiative, a space-based antimissile program backed by President Donald Trump, undertaken with defense startup Anduril and several other space technology firms.
SpaceX's June initial public offering has revitalized interest in space tech companies, even though the stock has been volatile. The stock of Elon Musk's rocket firm has fallen 44% from its post-IPO high, erasing over $1 trillion in market value.
Neel Kunjur, the co-founder and brother of Karan, launched K2 Space after a five-year stint working on SpaceX's Dragon spacecraft. Many startups founded by former SpaceX employees have attracted hundreds of millions in investment, among them Impulse Space, an in-space transportation firm valued most recently at $4.26 billion, and rocket manufacturer Relativity Space, now led by ex-Google CEO Eric Schmidt.
Since its founding in 2022, K2 Space has raised over $1 billion and currently employs 325 people. It plans to deploy the new funding to enlarge its workforce, particularly by bringing in specialized technicians from established satellite builders, said Kunjur, and to boost production capacity at its Torrance, California, facility.
The startup is also engineering a new satellite model that will produce five times the power of its current version, with a target to manufacture it by the end of 2028 and launch it as early as 2029, Kunjur added.
K2 Space's satellite platform could also support future orbital data centers, Kunjur noted. Elon Musk's SpaceX and Jeff Bezos' Blue Origin are among those that have announced plans to build data centers in space, promoting them as a solution to the growing computing demands of artificial intelligence systems.
