TORRANCE, Calif., Dec. 11, 2025 \/PRNewswire\/ — K2 Space, the California-based developer of large, high-power satellite platforms, today announced a $250 million Series C<\/b> at a $3 billion<\/b> valuation, accelerating delivery of a new generation of spacecraft built for the heavy-lift era. The financing follows $500 million in signed contracts<\/b> across commercial and U.S. government customers and is led by Redpoint<\/b>, with participation from accounts advised by T. Rowe Price Associates, Inc., and from Hedosophia, Altimeter, Lightspeed<\/b>, and Alpine Space Ventures.<\/b><\/p>\n

\n K2 Space’s GRAVITAS satellite undergoes final integration before its March 2026 flight
\n <\/p>\n

K2 was founded in 2022 on a single thesis: the rise of launch vehicles like Falcon 9, Starship and New Glenn will make it possible to build an entirely new category of satellite<\/b>. Satellites that are larger, higher power and more reliable<\/b>; that can be deployed in any orbit \u2013 LEO, MEO, and GEO<\/b> \u2013 rather than confined to one. These capabilities will become increasingly important as critical applications like communications and compute get pushed from terrestrial networks to space.<\/p>\n

“Space is becoming one of the most strategically important technology sectors, and it’s attracting investment because the underlying demand is real and accelerating,” said Elliot Geidt<\/b>, Partner at Redpoint<\/b>. “What stands out about K2 is how much core hardware they’ve built themselves. They’re not assembling a satellite; they’re redefining the architecture<\/b> needed for the next decade of missions.”<\/p>\n

“K2 is tackling one of the biggest limitations in the space economy: meaningful increases in power and scale,” said T. Rowe Price investment analyst Jason Leblang<\/b>. “Their approach isn’t incremental. They’re rethinking satellite design from the ground up, and the result is a platform that can support entirely new classes of missions<\/b>. That’s why we’re confident in the team and the trajectory.”<\/p>\n

Building the technical base for the next class of missions<\/b><\/p>\n

K2’s first two years were spent solving what the commercial supply chain hadn’t: the foundational subsystems required for large, high-power, highly resilient<\/b> spacecraft. The team designed the highest power hall-effect thruster ever flown \u2013 4x more powerful than anything that’s flown to-date; large solar arrays, designed to reliably generate maximum power; a radiation-tolerant avionics suite built to survive high radiation environments; massive reaction wheels; high voltage power systems; and much more.<\/p>\n

Those designs weren’t just theoretical. Earlier this year, K2 flew its hardware as part of a hosted-payload mission that validated the flight computer, reaction wheel, and avionics stack in space<\/b>, de-risking the core of the platform ahead of full-system integration.<\/p>\n

“Each subsystem had to be built to a new performance class,” said Neel Kunjur<\/b>, Co-Founder and CTO. “That engineering forms the basis of our high-power ‘Mega’ line, and it’s why we can take customers beyond the limits of the small-satellite era.”<\/p>\n

Four months to launch: The Mega Class satellite<\/b><\/p>\n

In March 2026<\/b>, K2 will launch GRAVITAS<\/b>, the company’s first production of its “Mega Class” satellite. While small relative to what K2 is designing next, the Mega Class satellite is on par with the largest satellites that have ever been produced. Mega is designed to fly on today’s workhorse rockets, including Falcon 9, Vulcan, and Ariane 6<\/b>, while delivering approximately 10\u00d7 the power<\/b> of other satellites in its class. Built from the outset for multi-orbit operations<\/b>, Mega is hardened for some of the harshest environments in the solar system and engineered with redundancy and reliability techniques<\/b> historically reserved for human-rated vehicles like Dragon and the Space Shuttle.<\/p>\n

The mission represents K2’s first spaceflight of the fully integrated, in-house system<\/b> and will open a comprehensive test campaign:<\/p>\n
