K2 Space

K2 Space designs and manufactures large-scale satellite buses capable of operating across low Earth, medium Earth, and geostationary orbits from single platform architectures. The company produces the majority of its spacecraft hardware in-house, including high-output Hall-effect thrusters, deployable solar arrays rated for 100+ kilowatt generation, reaction wheels, and radiation-tolerant avionics. The Mega-class platform accommodates payload masses up to one metric ton with approximately 20 kilowatts of power generation, while the Giga-class platform targets 15 metric ton payload capacity and 100 kilowatt power output for super-heavy launch vehicles. K2 Space operates a 180,000-square-foot manufacturing and testing facility in Torrance, California. The company emphasizes modular design principles that allow customers to configure payload capacity, propellant loads, and orbital parameters while maximizing launch vehicle fairing utilization.

Founded in 2022 by former SpaceX engineers Karan Kunjur (CEO) and Neel Kunjur (CTO), K2 Space maintains vertical integration across propulsion, power, and flight control subsystems to reduce production costs and qualification timelines. The company's first Mega-class satellite, Gravitas, is scheduled for launch in March 2026 on a SpaceX Falcon 9. K2 Space provides satellite platforms to commercial telecommunications operators, U.S. defense agencies, and scientific customers. The company is privately held and completed a $250 million Series C funding round in December 2025, bringing the valuation to approximately $3 billion.
