Duranium

Reshoring critical metal production

China and Russia control the world’s critical minerals. We can produce Titanium, Magnesium, Aluminum, Zirconium & Hafnium in the U.S. more profitably than any existing process, and carbon neutrally via co-production. Carbochlorination is the primary process for producing critical metals like titanium, hafnium, and zirconium, and was once the standard for magnesium. The problem: conventional carbochlorination relies on purchasing carbon feedstocks, wastes valuable byproducts, and is highly CO₂-intensive. Duranium changes this with a novel reactor that recycles CO₂ emissions back into feedstock (CO) while generating a valuable co-product (bleaching agents). This closed loop slashes emissions and delivers Chinese-level metal pricing without subsidies — unlocking the full potential of carbochlorination for U.S. critical mineral production.

Edyn

Nest for lawn and garden

The Edyn smart garden system lets you know what’s happening in your garden at all times. Whether you’re a novice gardener or managing a small-scale organic farm, Edyn is there to take the guesswork out of gardening. Inserted in the soil, the Edyn Garden Sensor gathers and analyzes data about changing weather and soil conditions. The Edyn App displays this data as a real-time snapshot of your garden, and pushes alerts and suggestions to maximize plant health. A separate component, the Edyn Water Valve, uses the data collected by the sensor to smartly control your existing watering system, watering your plants only when needed. With advanced tracking technology and intuitive design, the Edyn smart garden system keeps you connected to your garden or farm so you can grow healthier plants.

Entocycle

Automated factory to produce insect protein for farm animals.

The Insect Farming Company. We’re developing the world’s most efficient and sustainable way to produce protein. Insects are rich in protein and are a natural component of the diets of many fish and free-range poultry. Our technology is significantly more efficient at producing protein than traditional methods of production as our insects are vertically farmed and not restricted to floor space or area. Thanks to our automated system we can produce at industrial scale and offer farmers a cost-effective and sustainable alternative to soymeal and fishmeal.

Exosonic, Inc.

Developing supersonic UAVs as a pathway to quiet supersonic flight

Exosonic is an early-stage aerospace start-up based in Los Angeles, CA developing supersonic adversary air UAVs to support the adversary air training mission for both commercial and government customers. The goal is to mature these supersonic UAVs to become loyal wingmen (or collaborative combat aircraft) and eventually develop quiet supersonic airliners from the lessons learned and profits generated by the supersonic UAV product line. Founded in 2019, Exosonic has raised $4.5M+ in private capital and $2M+ in AFWERX funding. The team has 15 FTEs and is developing a subscale flight test vehicle to demonstrate autonomy and potentially crewed-uncrewed teaming with a first flight timeframe of Q2 2023.

F4 logo

F4

Automating compliance checks for engineering drawings

Built by former Tesla & SpaceX engineers, F4 is a platform that helps you catch and fix drawing compliance issues instantly. F4 ensures design engineers never release noncompliant drawings—and suppliers never misinterpret them. We help hardware teams eliminate costly scrap, rework, and miscommunication at the root. With a compliant drawing, F4 generates end-to-end drawing interpretations for standard definitions, inspection plan, and tolerance analysis application. F4 automatically interprets all GD&T symbols, datums, and notes based on the correct standards - no more second-guessing or misreading intent. Everyone from design to manufacturing sees the same definition, keeping teams aligned and avoiding costly miscommunication. F4 generates a complete inspection plan straight from the drawing, so quality teams know exactly what to measure, how, and where. This eliminates manual setup, reduces delays during first article inspection, and helps catch issues before they reach production. F4 gives engineers everything they need from the drawing to set up a reliable tolerance analysis, applicable features, and rule exceptions. By making it easy to bridge engineering drawings to tolerance analysis, teams can catch potential fit or function issues early - before parts are fabricated and assembled.

We Bring Customers to Your Dealership

The problem we solve: 56% of dealership leads arrive after business hours, and most dealers lose these potential customers to competitors who happen to be available 24/7. Missing after-hours calls alone costs the average dealership $1M annually in lost revenue. We built Flai to fix this - AI assistants that answer dealership calls 24/7, scheduling test drives, oil changes, or running outbound recall campaigns so no opportunity slips away. The result: No more missed opportunities, no more losing customers to competitors. Our founding team has built voice AI products at HappyRobot, scaled infrastructure at Uber for millions of users, and applied data science at Netflix to solve operational challenges. We're not just answering phones, we're helping dealerships win in an AI-first world where availability determine who gets the sale.
