Astro Mechanica

Government and Defense

Astro Mechanica is reinventing supersonic aircraft by innovating on engine, airframe, and systems that industry hasn’t in over 50 years. Our electric combined cycle engine, Duality, is the world’s first jet engine that's engineered for efficiency from takeoff to Mach 3+. This new propulsion technology enables the delivery of people and payloads anywhere on Earth in just hours, laying the foundation for a new operational paradigm: an affordable point-to-point global travel network that will make on-demand, high-speed air transport the new standard of travel.

Hazel builds AI-powered procurement software for U.S. state, local, and federal government agencies. We automate the full procurement process including requirements generation, market research, solicitation drafting, and proposal evaluation. Agencies use Hazel to save time and money while improving mission delivery.

AI-powered search platform that helps law enforcement identify suspects and solve crimes in seconds instead of hours. We transform existing camera networks into intelligent systems that can instantly search for people, vehicles, and behaviors across thousands of video feeds using natural language queries.

Abel takes police body camera footage and turns it into completed police reports. Currently American patrol officers spend one third of their shift writing reports - turning that to zero would increase the effective police force by 50%, radically changing US cities.

Ontra Mobility

Government and Defense

Ontra Mobility is founded by two former Googler engineers with PhDs in operations research. Ontra helps cities and other transit agencies increase ridership through data-driven planning and real-time optimization. The founders developed the software that powered MARTA Reach in Atlanta, GA and CAT SMART in Savannah, GA.

The rise of low-cost commercial drones has introduced a new class of asymmetric threats to U.S. national security. Off-the-shelf platforms now deliver ISR, contraband, or payloads with precision, while operating below radar coverage and beyond line-of-sight. These systems, often costing under $1,000, are capable of neutralizing multi-million-dollar defense assets. For drone detection to be viable at scale, sensors must achieve cost parity with the threat. In response, the Department of Defense established multiple initiatives to counter the rapid proliferation of uncrewed aerial systems. The Joint Counter-small UAS Office (JCO) coordinates policy and acquisition across services. The Base Defense Cross-Functional Team enables persistent perimeter security for CONUS and OCONUS installations. Falcon Peak, Red Sands, and related exercises are accelerating deployment of counter-UAS technologies in complex environments. This threat is no longer exclusive to military operations overseas. It now directly targets the U.S. homeland. In 2025, an executive order designated the protection of American airspace sovereignty a national priority, recognizing that uncrewed systems present both surveillance and kinetic risks within the United States. That same year, a domestic extremist plotted to destroy a Tennessee power substation using a drone rigged with C-4 explosives, a plan disrupted by undercover federal agents. In July 2025, an unauthorized drone collided with a rescue helicopter during disaster response operations in Kerr County, Texas, forcing an emergency landing and halting flood relief efforts. These are not isolated incidents, they reflect a broader shift in drone-enabled threats against homeland infrastructure and public safety. Guardian RF builds passive, radiofrequency-based drone detection systems for force protection and critical infrastructure defense inside the United States. Our systems are fielded under an AFWERX Direct-to-Phase-II SBIR with the 30th Security Forces Squadron at Vandenberg Space Force Base, deployed by local and state law enforcement, and integrated into commercial security operations. We were selected as a finalist for Falcon Peak 25.2, the Department of Defense’s premier counter-UAS exercise. Scout is a passive RF sensor for fixed, mobile, or temporary deployments. It detects and classifies drone control signals, including modified variants of DJI, Crossfire, and ExpressLRS, at standoff ranges. Scout supports direct integration into TAK and other operational APIs and is managed through GRF-SECURE, our secure interface for live monitoring, threat alerting, and forensic review. Mosaic extends coverage in austere environments, enabling persistent low-altitude monitoring and classification of non, Remote ID drones across complex terrain, without active emissions or mesh dependency. Built in the United States, Guardian RF delivers scalable, automated, and cost-aligned drone detection, passive by design and hardened for real-world deployment across the homeland.

Odo

Government and Defense

State and local governments buy $1.5TN worth of products and services from companies every year. However, the process of finding and winning government contracts is extremely fragmented, non-standardized, and time consuming today. Odo is the first AI-powered platform to help companies win state and local government contracts. Odo can find relevant contracts, draft proposals, and analyze why companies won or lost through public records sourcing. Our customers have saved up to 80% of time drafting proposals and increased their win rates.

Usul is the all-in-one platform to win defense contracts. We help governments adopt defense technologies faster than ever before. Get started at https://www.usul.com/

XTraffic is at the intersection of advancements in sensor technology and affordability. This means entire cities can affordably upgrade their infrastructure - and some already are. We are live in multiple cities, with both ongoing and successful pilots, corridors of multiple intersections, and soon to be entire cities. Our customers enjoy less traffic, better safety, and data on which to build their future.

Alchemy is a nanotechnology company based in Kitchener, Ontario with core operations in the automotive and defense sectors. Automotive - With the widespread adoption of ADAS systems in new vehicles, the cost of replacing a windshield in new vehicles has tripled to $1500+. We have developed a windshield protection film product line called ExoShield to help vehicle owners protect their windshields. Our ExoShield GT3 film is sold through 400+ aftermarket installers and car dealerships in 56 countries that carry and install it for vehicle owners. For Jeep Wrangler and Ford Bronco owners (google: broken windshield club), our ExoShield ULTRA DIY kits are available via our website and dropshipping partners. Defense - Over the last 3 years, we have been working with the Canadian Armed Forces to develop an infrared camouflage technology. We have received two contracts from CAF to develop our technology. Our solution has the ability to be integrated into the uniform directly (adding just 5-10g of weight vs. 600-18,000 kg of weight for other alternatives), has outperformed all existing NATO alternatives in multiple CAF field trials, and is receiving support from major elements of CAF for our next contract. This technology can also be adapted for other individual camouflage integrations (face paint and individual nettings) and for mobile camouflage applications (vehicle nettings and vehicle paints).
