The fight has changed. Capability that once depended on large, centralized systems is moving closer to the operator. Performance Drone Works (PDW) is a defense technology company building multi-mission aerial robotic systems for that reality. We are creating a new category of tactical robotic systems designed to bridge the gap between low-capability drones and high-end platforms. Just as important, we are building the industrial capacity to produce those systems at scale in the United States. Everything starts with the operator. We learn from real-world use, move quickly, and build systems designed to perform when the mission depends on them. Our mission is simple: put decisive airpower in the hands of every operator.

Drooid develops micro-scale autonomous swarms for reconnaissance, breaching, and high-risk mission automation. Our aerial ornithopters and ground crawlers are palm-sized, low-cost, and expendable, allowing operators to deploy dozens to hundreds of units simultaneously without the risk or noise of traditional drones. Using onboard AI, mesh networking, and a unified command interface, Drooid swarms can map environments, locate threats, clear rooms, or secure perimeters with minimal operator input. Drooid brings next-generation autonomy to the tactical edge — delivering capabilities previously reserved for much larger, more expensive unmanned systems.

VOGIC AI is a deep-tech startup building the next generation of AI-powered video intelligence systems for high-stakes sectors like Defense, Smart Cities, and Industrial Safety. Our core innovation lies in Vision-Language Models (VLMs) — proprietary AI agents that can watch, understand, and respond to real-world video feeds. From facial recognition and POI tracking in secure compounds to real-time alerts for critical events in smart factories, we’re redefining how humans and machines interact with visual data. We work closely with defense agencies, law enforcement, and smart infrastructure partners, and our deployments include collaborations with the Indian Army and multiple Smart City Missions. Recently, we were recognized as one of the Top 10 Innovators globally by the Toyota Mobility Foundation (TMF) for our AI-led urban crowd management platform, Behtar-Way, built for the old city of Varanasi.

Asgard Aerospace is building a coordinated industrial network that expands U.S. aerospace and defense manufacturing capacity. The company operates an advanced manufacturing and integration facility in Austin, Texas, and pairs this physical capability with Launchbelt, a secure digital platform that connects fragmented suppliers into a unified production ecosystem. Launchbelt provides a defense-aligned digital thread for travelers, traceability, QA, and compliance, with intelligent routing that evaluates capability, capacity, and performance across thousands of facilities. This creates predictable, high-reliability throughput for space, defense, aviation, UAS, and eVTOL programs. Asgard’s Command Forge facility serves as the anchor node of the network. It delivers composites, machining, harnessing, and integrated assembly with AS9100D and ITAR/CUI infrastructure, and it validates Launchbelt workflows through live production cycles. Each Forge is a replicable model that strengthens national aerospace capacity and supports program-level certainty for government and commercial partners. Asgard establishes a new category in the industrial base: a defense-aligned manufacturing network that synchronizes the operations of many facilities through a combined physical and digital platform. The result is faster onboarding, reduced coordination friction, higher quality, and an industrial system built for modern aerospace scale.

Amaratek provides specialized contract services to the U.S. Department of Defense and other government and commercial partners, with a focus on developing innovative technologies and practical solutions to complex technical challenges. Our work has included the development of biological systems for the neutralization of chemical warfare agents, including the successful delivery of a working system to the U.S. military. Our experience supporting defense-related programs has given our team a unique understanding of how to develop reliable technologies for demanding environments where performance, safety, and operational reliability are critical. We recognize that many of the capabilities and technical approaches developed for military applications can also provide significant value in civilian and humanitarian settings. Amaratek applies this experience to civil government and international projects where the need for resilient and dependable infrastructure often mirrors the challenges faced in defense environments. Areas such as public health, water treatment and management, energy systems, transportation, and environmental protection require many of the same principles of reliability, adaptability, and innovative problem-solving. In addition to our work with U.S. government agencies, Amaratek provides technical services and expertise to foreign governments, nongovernmental organizations (NGOs), and social entrepreneurs. We work collaboratively with our partners to understand their specific challenges and develop practical, sustainable solutions that can be implemented in real-world environments. Our goal is to take the technical expertise and problem-solving capabilities developed through demanding defense and government projects and apply them more broadly to challenges that improve the resilience, safety, and quality of life of communities around the world.

LegacyCore Holdings, Inc. is a defense and enterprise tech conglomerate fundamentally re-architecting how global data is stored, transmitted, and protected. We build un-jammable hardware networks, air-gapped server vaults, and zero-bloat operating systems designed to withstand state-sponsored cyber threats and prevent catastrophic global IT outages. We do not rely on legacy third-party vendors. We build from the bare metal up. Our technology is "Dual-Use"—engineered to secure commercial sectors (Healthcare, Finance, Critical Infrastructure) while meeting the rigorous demands of tactical defense applications.
