Side-by-side comparison of AI visibility scores, market position, and capabilities
Impulse Space raised $150M Series B in 2024 for its high-performance chemical propulsion spacecraft (Mira and Helios) that provide in-space transportation, enabling rapid satellite deployment and orbital transfer.
About
Impulse Space develops orbital transfer vehicles (OTVs) — spacecraft with high-performance chemical propulsion systems that can transport satellite payloads from launch vehicle deployment orbits to their operational orbits, or maneuver constellations for rapid response missions. The company's Mira vehicle targets LEO and MEO missions while the larger Helios vehicle aims for GEO and cislunar missions.
Second Front Systems' Game Warden platform achieved DISA IL5, FedRAMP High, and GovRAMP accreditations in 2025; became the first authorized software platform on AWS Marketplace for DoD JWCC; named NATSEC100 for third consecutive year.
About
Second Front Systems is a defense technology company focused on accelerating the delivery of commercial software to US national security missions. Founded by veterans of the US intelligence community and military, Second Front builds Game Warden — a DoD-accredited software delivery platform that enables commercial software companies to deploy their products on classified and unclassified government networks without navigating the full FedRAMP or DoD authorization process themselves. Game Warden acts as a "platform-as-a-compliance-service," handling the accreditation burden so software vendors can focus on their product.
