Y-Combinator backed Nox Metals raises $11.5m seed round for metal manufacturing in Detroit

Seven month-old Detroit startup Nox Metals has closed an $11.5 million seed round, giving the young manufacturing business fresh capital as it pushes to scale an AI-driven approach to industrial metal supply. The company operates in Southwest Detroit and says its software and automation can compress lead times for custom aluminum blocks used in CNC machining from days to seconds. The round was led by Hyperion of New York, with participation from Y Combinator, Anduril founder Palmer Luckey, RoboStrategy, Alumni Ventures, Operator Collective and Dallas-based DTX Ventures.

The company said in its own release on the raise that it “exists so America can build 100x more factories and technologically abundant industrial capacity in the West” and describes itself as part software company, part industrial rebuild. Company materials describe a plan to build vertically integrated, automated factories that can deliver production-ready metal faster and at lower cost than conventional service centers, with a focus on sectors including aerospace, defense, automotive tooling and small machine shops.

Founder and chief executive Zane Hengsperger framed the reindustrialization play or America’s metal supply in the post announcing the raise on the company’s blog, saying “our metal has gone to space. It has protected our troops. It is in your car and in the machine that scanned your chest. It is all around us. And we can't stop supplying at warp speeds.” Hengsperger also said Nox Metals plans to revive a World War II-era, 30,000-square-foot factory in Detroit this summer and deepen its reliance on technology as it continues to expand.

There are, however, differing accounts in the market about the size and timing of the company’s financing. StartupIntros says Nox Metals has raised $5 million across one round, while a later digest from tbpndigest reported a $4.6 million seed close in September 2025 tied to Factory 1, a metals cutting and distribution operation aimed at machine shops across the Midwest. That report said the company was also pursuing debt financing to help fund inventory and described supplier relationships as the main constraint on growth.
