Arda Emerges from Stealth to Speed Up American Manufacturing

Founded by former OpenAI Chief Research Officer Bob McGrew, Arda is deployed as part of ArsenalOS at Anduril, which was the company's first design partner and customer.

Arda has raised $232 million total from Accel, Altimeter, Founders Fund and Khosla Ventures, with participation from XYZ Venture Capital, 8VC, SVAngel and Felicis.

SAN FRANCISCO, October 20, 2026--Arda Industries today launched from stealth with $232 million in funding to speed up American manufacturing. Its software helps manufacturers quickly turn new product designs into working assembly lines. It is the first step toward a larger vision: automated robotic assembly lines that update as designs change, making it possible to build fast-changing products in the U.S.

Think of a 7,500-piece Lego set that arrives as a finished model with no instruction book. To build it from scratch, you would have to figure out the assembly order, write the instructions, and lay out the stations. Today's phones, drones and other advanced hardware products change rapidly, requiring manufacturing engineers to work out how to assemble them each time. Arda's AI agent does that work from the product's CAD files and other design artifacts, so a design change reaches the factory floor without halting production.

"I kept asking: why can we design the next generation of products in America, but not build them here? When a product changes every year, the factory has to be able to change with it," said Bob McGrew, founder and CEO of Arda. "Manufacturing leaders told me their products change constantly, and manufacturing engineering can't keep pace. Their designs change at software speed, but their factories don't. So, we built the technology platform that solves this problem. Today, U.S. manufacturers designing innovative consumer hardware products at scale can only make them in Asia. Imagine a fully automated version of Shenzhen in West Texas - that's what we want to make possible."

Already Deployed at Anduril

Anduril Industries is already using Arda's product as part of its ArsenalOS manufacturing software. The two companies began working together before Arda was incorporated. Anduril found that in many cases, Arda turns days of work into hours, and hours of work into minutes. Basic work instructions that once took 10 hours can now be created in 15 minutes, while more complex engineering workflows that previously took up to 30 hours now take roughly 2.5 hours.

"Our manufacturing engineers are doing two hard things at once. They're keeping up with design teams that iterate constantly, and they're scaling production to meet demand," said Matt Grimm, co-founder and COO of Anduril Industries. "Arda helps them get design changes onto the floor faster and catch potential issues sooner. We would be behind on our production goals without it."
