Automation will not be capable of replacing these skilled roles - to create a safe, prosperous future, we must secure the next generation of manufacturing talent.

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.

Praxis AI builds manufacturing specific agents capable of reasoning and processing complex situations. Our engineering copilot predicts and prevents machine failures in real time by solving problems the same way an engineer would.

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.

We're building autonomous sheet metal factories. Sheet metal is a large ($200b+ in the US) industry heavily reliant on human labor. If you're building something in the real world, it's almost a certainty that you will use sheet metal in some capacity. It's used in automotive manufacturing, aerospace, consumer goods, defense, and many more verticals. The industry mostly operates the same way it has for the last 50+ years. We're making a 10x better experience for people to get sheet metal parts manufactured. We are vertically integrated and build everything from our quoting engine to the physical automation inside of our factory. Factories should own automation as a core in-house skill. Today we sell laser cut and bent sheet metal parts. Users can get instant quotes through our website (and eventually through integrations build on top of our API). We build custom internal software to command and control the operations of the factory. Right now we are actively working on fully automating the production of laser cut parts including scheduling, material movement, laser configuration, etc. Orders will be able to come in, and our software will control the factory and output parts ready to ship.

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.

Auto parts retailers get product data from hundreds of manufacturers that is inaccurate and inconsistent, often with big gaps in key values. They currently have a team of "catalog managers" who are required to process and enhance this data line by line, resulting in a week to months long lag between receiving product data and actually being able to start generating revenue from those products. Versable leverages AI to scan the web for tens of millions of auto parts listings, and uses a fine-tuned LLM with RAG to instantly process, enhance, and transform data. With just a part number, Versable is able to generate market-ready titles, product descriptions, and specs, in any format that's needed.
