Making Chips Podcast for Manufacturing Leaders Reindustrializing America: How Zane Hengsperger Is Reinventing the Metal Supply Chain, 510
What happens when a 26-year-old machine shop kid decides the real bottleneck in American manufacturing isn't machining—it's metal supply?
In this episode, we sit down with Zane Hengsperger, founder and CEO of Knox Metals, to talk about building a modern service center powered by AI, automation, and software. Zane's mission is bold: supply every factory in America in under 24 hours at a fair, transparent price.
Raised in his father's injection molding shop, Zane grew up on shop floors before pivoting into software, startups, and eventually reindustrialization. After publicly sharing his ideas online, Y Combinator reached out—and within 24 hours, he had funding and a flight to San Francisco.
We explore what it takes to modernize the metals supply chain, the friction of accessing domestic mills, the realities of startup logistics, and why focusing exclusively on aluminum plate might be Knox's smartest strategic move yet.
This is a conversation about speed, ownership, risk, and the future of American manufacturing—not just at the machine level, but across the entire supply chain.
