While others are reducing the size of satellites, K2 secured $500 million to develop large satellites and deploy AI in space.
Many satellite startups are focused on developing smaller satellites, but K2 Space is intentionally taking the opposite approach. Recently, the company secured $500 million in funding to expand its operations.
On Thursday, K2 announced it had completed a $500 million Series D funding round, achieving a valuation of $6.8 billion. This round was led by Kleiner Perkins and ICONIQ, with additional backing from Alphabet’s CapitalG, Lightspeed, and ARK Invest. This valuation more than doubles the $3 billion it was worth just a few months ago. K2 has raised over $1 billion in total, supported by more than $1 billion in signed contracts.
The company’s strategy is unconventional. While most of the industry aims to produce smaller satellites to reduce launch expenses, K2 believes that larger satellites with higher power capacity can achieve more in orbit.
Evidence of this approach is already in space. Its first "mega-class" satellite, Gravitas, launched successfully in March aboard a SpaceX Falcon 9 rocket. Weighing two tons and generating 20 kilowatts of power, it carries multiple payloads for clients, including the U.S. military, according to GeekWire.
K2 manufactures over 85% of each satellite in-house. Its manufacturing facility in Torrance, California, spans 180,000 square feet and is designed to produce up to 100 satellites annually. The company asserts that this in-house production model enables it to create large satellites efficiently and cost-effectively.
A significant portion of K2's contracts is with military clients. The company intends to deliver 30 satellites for SES’s meoSphere network, construct spacecraft for the Anduril-led Golden Dome missile defense initiative, and serve as a bus provider for a U.S. Space Force satcom project, marking its first official contract with the Pentagon. This aligns with a broader trend of increased investment in the defense space sector.
Looking ahead, K2 has an ambitious plan for late 2028, when it aims to launch a 100-kilowatt “Giga” satellite designed to facilitate “massive amounts of compute on orbit.” In more straightforward terms, this represents a move toward establishing AI data centers in space, a concept highlighted by its CEO in a conversation with Bloomberg.
K2 was established in 2022 by brothers Karan and Neel Kunjur, the latter having previously worked as an engineer at SpaceX. This funding round occurs amidst a surge in investment across various sectors of the space industry, including launch services, defense, and orbital infrastructure.
However, there are significant risks involved. Manufacturing 100 large satellites annually is a manufacturing challenge that has yet to be accomplished, and space-based data centers are still several years away from being a reality and remain unproven. K2's upcoming mission, Trinity, plans to deploy multiple satellites in early 2027. The transition from one satellite to hundreds is their objective, and whether orbit will become the next location for data centers is the larger gamble they are taking.
