G4 IN DEFENSE

We invest in greatest science, innovation and creativity around the world.

A defense‑technology company that designs, develops, and manufactures advanced autonomous systems—airborne, maritime, and terrestrial—for defense and security applications.

A vehicle intelligence software company that provides tools and platforms to design, test, and deploy autonomous driving systems and advanced driver‑assistance systems (ADAS). They serve a wide range of industries—automotive, trucking, mining, agriculture, defense, and more—by helping engineering teams build safe, AI-powered vehicles faster and at scale.

Focused on revolutionizing aerospace and defense manufacturing through highly automated, software-defined factories. They aim to produce precision parts for rockets, satellites, jets, and drones up to ten times faster and at half the cost compared to traditional methods. Hadrian achieves this by utilizing advanced automation, AI, and robotics in their factories.

A company that provides in-space transportation services, essentially acting as a “space tug” to move satellites and payloads between different orbits. They design and manufacture orbital transfer vehicles (OTVs) that can transport satellites from low Earth orbit (LEO) to other destinations like geostationary orbit (GEO), the Moon, or even Mars.

A wind and solar-powered unmanned surface vehicles (USVs) that collect oceanographic and atmospheric data. They are designed to operate in remote and harsh ocean environments, collecting data that can be used for various applications, including climate and environmental monitoring, fisheries research, and maritime defense.

A U.S.-based aerospace startup on a mission to build the world’s first in‑space factories—tiny manufacturing labs operating in microgravity to create high-value products, especially pharmaceuticals, which are then safely returned to Earth inside reentry capsules.

A German aerospace startup that design, manufacture, and market modular unmanned aerial systems (UAS)—essentially advanced UAV drones—intended for military, security, reconnaissance, and dual-use applications.

A Ukrainian defense‑tech startup specializing in intelligence, surveillance, and reconnaissance (ISR) drones and the integrated software that powers them.

A defense technology company focused on designing, manufacturing, and deploying unmanned systems, particularly drones, for military applications.

A Ukrainian technology company specializing in the development and production of unmanned aerial vehicles (UAVs) and unmanned aerial systems (UAS) for both military and civilian applications.
