We’re becoming the AI layer for the multi-trillion-dollar home-services market.

Our agents run hardware engineering tasks that normally take hours or days in just a few minutes, allowing engineers to process 100x more data and information. Our platform allows hardware engineers to orchestrate agents for tasks such as analyzing failures across entire test campaigns, pulling the right data and KPIs from their databases, checking how conditions (like temperature or load) affect performance and reliability, and then document findings in reports and dashboards.

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.

At Axial Composites Industries we are building the first non-planar manufacturing cell to manufacture carbon fiber parts at the speed of software for the upcoming autonomous age We believe in the following: • Aerospace and robotics manufacturing is going exponential • Thermoplastic composites will be the foundational materials for such applications Our mission is to equip the West with novel composite manufacturing methods that will act as the backbone of the skyrocketing demand in autonomous systems. Our method prints stronger and lighter parts by leveraging fiber anisotropy to our advantage. We can manufacture large composite structures in a day rather than weeks.

We're building an AI powered platform for engineers that are building new robots and machines. We allow users to invent and modify machine designs in a matter of minutes, not years. Ayna and Andy, the co-founders, met during their time at Harvard and started this in 2024 as their programs were wrapping up. We're commercializing 10+ years research done by our team at Harvard and MIT on this space. Our team wrote the very first papers on applying GenAI and optimization algorithms to compose robots from parts and applying computational design to fine tune machine designs. We're bringing in our deep knowledge of modifying equipment and integrating it into factories keenly understanding what makes hardware hard. We take in parts under consideration, constraints and tasks at hand and our algorithm formulates and fine tunes from 100s of possible design options. All in a few clicks, so engineers can push hardware to market faster and companies can benefit from the inventions being done by their R&D teams. We already have two paying customers in the OEM and system integrator spaces. We are venture backed and supported by a GBP 2.5MM grant by ARIA, the UK Government's invention agency.

Foundation Industries supplies components to hard tech companies with a sharp focus on quick turn ability. Our manufacturing processes are purpose built for the high mix nature of prototype work which allows us to command better margins and turn times. One of the major reasons U.S. Manufacturing has fallen behind is a lack of urgency. If I were to order a part in Shenzhen at 8 AM, it would be on my desk by lunch time. This compounds over time and we look to bring that same power law back to the Unites States starting in the Bay Area. Our first capability that we are starting with is high precision 5 axis milling. If you are in need of parts on a quick turn feel free to reach out to us at : founders@foundation-industries.com. We are doing a controlled release of the service to if you would like to give us a shot we will forward you a link and access key.
