K2 Space

K2 Space is a Torrance, California-based satellite manufacturer that builds large, high-power spacecraft platforms, running counter to the industry's long-running trend toward smaller satellites. The company's thesis is that heavy-lift and super-heavy-lift launch vehicles such as Falcon 9, Vulcan, Ariane 6, Starship and New Glenn make mass less of a constraint, so satellites can be built larger to deliver more electrical power and payload mass per spacecraft at lower cost per unit of capability.

Its current product is the "Mega Class" platform, designed to carry up to roughly 3,000 kg of payload and generate about 20 kW of power — described by the company as roughly 10x the power of comparable constellation-class satellites (typically ~2 kW and ~200 kg payload). Mega is built for multi-orbit operation (LEO, MEO and GEO out to 36,000 km), with radiation-tolerant avionics, redundant systems, high-voltage power, large twin 10 kW solar arrays, high-power Hall-effect electric propulsion and high-delta-v capability. K2 states that stacking 10 Mega Class satellites per launch vehicle yields 200 kW of power to orbit per launch. A follow-on "Giga" class platform delivering roughly 100 kW per satellite, sized for Starship and New Glenn, is planned for introduction in the second half of 2028 and is positioned as a foundation for on-orbit AI-scale compute, cross-orbit high-throughput networks and large space telescopes.

K2 says it produces more than 85% of each satellite platform in-house (the company website cites 80%), a vertical integration strategy intended to control cost, reliability and production rate. Manufacturing is centered on a 180,000 sq ft Torrance factory sized for up to 100 satellites per year, supplemented by an engineering office opened in the Seattle region in 2026.

Founding story

K2 was founded in 2022 by brothers Karan Kunjur (CEO) and Neel Kunjur (CTO) on the thesis that new heavy-lift launch vehicles would enable an entirely new category of larger, higher-power, more reliable satellites; the company emerged from stealth in 2023. Neel Kunjur previously developed and integrated avionics systems for Dragon spacecraft at SpaceX and served as a Mission Director; Karan Kunjur helped lead an AI startup from seed to a nine-figure exit after a decade at BCG. The company describes itself as founded by former SpaceX engineers.

Business model

K2 Space manufactures and sells complete high-power satellite platforms (buses) and integrated spacecraft under commercial constellation contracts and U.S. government/defense programs, including as a bus supplier to prime-led teams. Development has also been partly supported by government funding mechanisms; the roughly $60 million Gravitas project received support through a U.S. Space Force Strategic Funding Increase (STRATFI) agreement combining government funding with private capital and small-business research awards.

Revenue derives from contracted satellite builds and deliveries for commercial operators and government programs; the company reported over $1 billion in signed commercial and government contracts as of July 2026, up from $500 million in December 2025.

Traction

K2 flew a smaller hosted-payload demonstration mission in January 2025 that validated its flight computer, reaction wheel and avionics stack. Its first Mega Class satellite, Gravitas — roughly 2 metric tons and carrying 12 payloads — launched in March 2026 and is operating on orbit, testing a 20 kW Hall-effect propulsion system and an orbit-raising maneuver from LEO toward MEO. Signed contracts exceed $1 billion, including an initial tranche of 30 satellites for SES's planned "meoSphere" MEO network. Total capital raised exceeds $1 billion. Headcount was reported at nearly 300 as of July 2026. The next mission, Trinity, is scheduled for Q2 2027 with multiple satellites deployed to different orbits and a long-range optical communications test; operational commercial and national security constellations are targeted to begin deployment in 2028.

Latest developments

In July 2026 K2 raised a $500 million Series D at a $6.8 billion valuation led by Kleiner Perkins and ICONIQ, bringing cumulative capital above $1 billion, and opened an engineering office in the Seattle region. Recent program wins include SES's meoSphere MEO network (initial tranche of 30 satellites), a bus-provider role on the U.S. Space Force Protected Tactical Satcom-Global program, satellites supplied to Anduril for the Golden Dome for America space-based interceptor program, and a Space Force effort to test laser communications for missile defense. The company plans to introduce its 100 kW Giga-class satellite in the second half of 2028 and to launch its Trinity mission in Q2 2027.
