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.

As an example, the Boeing 777 is made up of over 3 million parts sourced from manufacturers around the world. These manufacturers must complete quality documentation for every part on this aircraft (machined parts, printed circuit boards, wire harnesses, assemblies, and more). GroundControl helps manufacturers complete this required documentation accurately, in minutes instead of days.

Bucket Robotics is making defect detection faster, easier, and more deployable — starting with the 250M lbs of plastic wasted annually in U.S. manufacturing. Our platform turns CAD files into defect detectors. We generate synthetic, photorealistic training data to help factories catch flaws before they ship. No manual labeling, no real defects required. Our models deploy to edge hardware and integrate easily into existing automation stacks. We come from the self-driving world (Argo AI, Uber ATG, Stack AV), where we built reliable perception in high-noise, real-world environments. We're applying that experience to manufacturing: robust sensing, user-friendly interfaces, and fast iteration cycles. Manufacturers hesitate to adopt new sensing due to data concerns, integration risk, and poor UX. We’ve handled petabytes of regulated autonomy data — and built systems that earn trust. Legacy vendors like Keyence and FLIR offer hardware-centric tools with bloated pricing and outdated software. We’re building the opposite: flexible, modern tools that engineers want to use. Manufacturing is in the middle of a $700B automation wave across North America. Bucket Robotics is building the quality control infrastructure to match.

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.

Bravi builds AI agents for home service companies so they can sell more. Our platform answers calls, chats, and emails instantly, pre-qualifies prospects, and follows up until a quote is sent, turning missed opportunities into revenue. We’re already working with top installers in shutters, solar, and construction. For example, one client uncovered 1000+ missed calls per month that Bravi now converts into $1M+ of potential revenue.

Crowdfunding has fueled an increase in innovative product companies turning to Chinese factories for production. Yet, Chinese factories seem undifferentiated because they all make the same, unverifiable claims of excellence. This results in competition centered on price. Factories are forced to under-bid contracts to win business, but often, they later surprise the customer with quality problems and delays. This process is broken. We install cameras and remote monitoring software on the assembly line, and this ensures compliance with test protocol, improves quality, reduces liability, and helps fight warranty fraud. We charge a nominal per-unit fee to the OEM and revenue share with the factory when they demonstrate compliance with quality standards (whether units pass or fail). It encourages better behavior from factories and rewards those who perform with an audit trail of good performance that helps them win new foreign business. On average, defect rate will fall 75% within 5 months of deploying Assembly at a factory.

Jeevy Fabrication is an AI-powered contractor that connects complex weld jobs to the best-fit shops—fast. We deliver top-tier QA and total transparency, all at better traditional outsourced pricing.

Vastrm Fashion™ (pronounced vas' trum) Vastrm was started to solve a basic problem: Shirts that don’t fit well! Mass produced shirts were meant to accommodate a wide variety of body types with one standard size, and different brands have different sizing standards, making shopping difficult--many men must shop in 4 - 5 different stores before finding a shirt that actually fits! By providing a home try on program and giving the ability to make custom fit adjustments to all of their apparel, Vastrm allows its customers to finally hone in on and find the perfect fit for their unique body types. Tang came up with the idea for Vastrm, which is a Sanskrit word for cloth, when a customer told him he had purchased a perfect shirt in Italy and has never been able to find the same fit again. He was considering flying back to Italy to track the shirt maker down, but Jonathan managed to adjust Vastrm shirts to the same fit.

LineWise is building an AI assistant for manufacturing teams to operate and resolve production issues, from defects to breakdowns.

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.

Look around you - everything you see that was made with wood a designer conceived and then a woodworker has made. Most of the time, something went painfully wrong. 60% of the $1.4T global woodworking market is serviced by small businesses with inefficient, manual processes - Cutr is digitising their workflow. This market is massive, chaotic and surprisingly manual. Woodworkers are mostly offline, hard to find and even harder to vet. They need help with critical back-of-house jobs like quoting and capacity planning. Customers have no idea where to find them and need help asking the right questions & providing the right info to get their job produced correctly. Cutr solves discovery, pricing, payments and workflow for the woodworking market. Our users simply upload a file, accept an instant quote, and get their parts delivered. To make that possible we do the heavy lifting: filechecks, automated quoting, matchmaking, creating job packages, tracking changes & updates, logistics and payments. Cutr saves time, cuts costs and ensures quality with a smooth workflow.
