Starfish Space

Starfish Space creates Otter, an autonomous satellite servicing vehicle. Otter docks with satellites using electric propulsion. It handles life extension by keeping satellites in position and disposal by moving them out of orbit. The vehicle is much smaller and cheaper than other options. Otter Pup 2 tested docking in low Earth orbit.
Stellar Project

Stellar Project creates laser terminals that let small satellites send data faster than radio systems. LaserCube works for links to Earth or between satellites, and fits on CubeSats. They also check spacecraft designs against space debris and weather risks to predict issues for insurance.
Stratobotic

Stratobotic sells CubeHAPS platforms, small and reusable devices that operate at 20km altitude. The company runs Earth observation services to produce datasets in visible, multispectral, and IR bands, sold as archives or from on-demand flights. It also transports custom payloads like telecom gear, weather tools, or science equipment. Applications cover urban monitoring, precise farming, asset checks, situational awareness, and environmental tracking. Customers can buy full kits with ground stations.
SWISSto12

SWISSto12 develops compact geostationary satellites and advanced radio frequency hardware that support satellite communications services. Its HummingSat platform offers smaller, lighter GEO satellites that cut launch costs while delivering long‑term connectivity in orbit. The company also produces 3D‑printed antennas, filters and waveguides used in space, in the air and on the ground, helping operators upgrade coverage, capacity and link reliability.
Kepler Aerospace

Kepler Aerospace develops small satellites for space operations. It designs, manufactures, and manages defense systems used in missions. The team contributes to key space systems with practical expertise in satellite tech. This work supports satellite swarms and surveillance projects.
Kleos Space

Kleos Space runs satellites that pick up radio frequency transmissions over key areas. The company processes this data to find the exact locations of signals from ships, vehicles, or other sources involved in illegal fishing, smuggling, piracy, or people trafficking. Customers get ready-to-use intelligence through an API for defense, border security, search and rescue, and monitoring strategic zones. This works day or night, in any weather, unlike imagery limited by clouds or distance.
KaleidEO

KaleidEO builds high-resolution optical multispectral payloads that satellites use to capture earth images. The company tests edge computing on these payloads to process data right in space, cutting down transfer needs. It handles payload services, data infrastructure, insights delivery, and in-orbit operations, while partnering for satellite manufacturing, launch, and deployment. A fleet of four satellites will launch in 2026 to deliver daily frequency imaging for users.
K2 Space

K2 Space constructs big satellites that provide more power and mass in orbit at reduced costs. The company makes 80% of each satellite in-house for faster production and reliability. Mega Class satellites offer 20kW power, 10 times higher than typical constellation satellites, and work in LEO for low-latency sensing, MEO for global networks with fewer units, and GEO for broadcast coverage up to 36,000 km. Designs include redundant systems and high-thrust propulsion to handle tough radiation.
Sisir Radar

Sisir Radar develops synthetic aperture radar (SAR) systems that work on ground platforms, drones, planes, and satellites in P, L, and X bands. The radars create detailed 2D and 3D images day or night in any weather, including fog, rain, or smoke. They support defense surveillance, agriculture checks, mining operations, infrastructure watch, and disaster response. Resolutions reach 0.75 meters for L-band and 2.5 meters for P-band, with abilities to see through foliage and shallow ground.
Array Labs

Array Labs designs, builds, and operates radar satellites. These satellites capture high-resolution images day or night in any weather using synthetic aperture radar. They create single-pass 3D elevation models up to 10 cm resolution for global terrain mapping. Multistatic systems enable real-time tracking of moving objects on ground, sea, or air. Turnkey sensors integrate easily into satellites for space domain awareness and navigation in GPS-denied areas.
