Rule 1 Ventures spent years turning freight, finance and security headaches into B2B software. Now the Atlanta firm is applying the same operator-first logic to aerospace and defense - where access, speed and execution matter as much as capital.
Sustainment is an Austin-based public benefit corporation building an AI-native software platform for industrial sourcing, procurement, and supplier management. Founded in 2020 by military veterans and technology executives, it helps commercial OEMs, contract manufacturers, and Department of Defense teams find suppliers, run RFQs, manage purchase orders, and track supplier performance - with the broader mission of strengthening a resilient, domestic U.S. manufacturing base.
Luke Fischer is the co-founder and CEO of SkyFi, an Austin-based Earth intelligence platform that lets businesses and governments order satellite imagery and analytics on demand, the way you'd hail an Uber. A former U.S. Army Special Operations aviator with 16 years on active duty, Fischer went on to lead flight operations at Uber and government operations at Joby Aviation before becoming an entrepreneur-in-residence at Shield Capital. He teamed up with investor Bill Perkins, who was frustrated that buying satellite imagery could take three to six months, and together they built a marketplace connecting more than 50 imagery providers. In January 2026 SkyFi raised an oversubscribed $12.7 million Series A to push deeper into AI-driven analytics.
TERN is an Austin-based startup building IDPS (Independently Derived Positioning System), an AI-powered, software-only alternative to GPS. Instead of relying on satellite signals that can be jammed, spoofed, or blocked by tall buildings and tunnels, TERN's AI reads the sensors already inside vehicles and phones - accelerometers, gyroscopes, speedometers - and matches that motion against existing map data to figure out exactly where you are. Founded by AI engineers and former U.S. special operations personnel, TERN serves automakers, delivery fleets, emergency services, and defense customers who cannot afford to lose their location when the signal drops.
Roam Robotics builds lightweight, air-powered wearable exoskeletons that augment human strength, endurance and mobility. Founded by Ekso Bionics veteran Dr. Tim Swift, the San Francisco company replaced the heavy metal of traditional exoskeletons with plastic, fabric and pneumatic actuators - making robotic assistance cheap and light enough to wear all day. Its products span consumer skiing (Elevate), medical knee osteoarthritis relief (Ascend), and military performance (Forge), with clinical data showing 46% average knee-pain reduction and up to 2x strength and endurance gains.

Jeff Karras is a General Partner at America's Frontier Fund and co-founder of Alter Venture Partners, bringing over 20 years of venture capital experience to the intersection of deep tech, national security, and U.S. strategic competitiveness. With more than 40 investments and 23 exits - including 6 IPOs - he has backed companies spanning semiconductors, advanced manufacturing, synthetic biology, and AI. Before pivoting to frontier tech, he helped build SingTel Innov8's North American and Israeli operations and spent nearly a decade at Levensohn Venture Partners. A licensed pilot based in San Francisco, he is among a small cohort of investors who believe the most important technology companies of the next decade will emerge from the overlap of commercial innovation and government-scale problems.
