Launch HN: ProvenMetal (YC S26) delivers circuit boards in days instead of weeks
Points and comments are a snapshot, not live.
ProvenMetal offers 5-day PCB fab and assembly with US-based supply chain.
ProvenMetal (YC S26) delivers PCBs in as fast as 5 days with no expedite fees. The company sources all parts from US suppliers, runs fabrication and assembly with US partners it manages, and ships every board with a full quality record. It offers a 7-day standard turn and fully domestic builds. The service targets hardware teams who need fast iteration, including defense and drone sectors.
What commenters are saying
Commenters are cautiously optimistic but skeptical about scalability. Defense and automotive are seen as the main domestic drivers. A top comment notes that the entire US supply chain needs to support such a service, and the company acknowledges it cannot beat China on price. A CTO from AISLER (EU) explains that 6-layer boards are expensive due to low demand; Eurocircuits and Aisler are cited as EU alternatives. A user asks about pricing, suspecting it will be high.
Some commenters question how the business will remain competitive globally outside defense. The company counters that owning the full stack (design to testing) provides long-term value beyond what OSH Park offers. A user with a board assembly line notes it sits idle, suggesting limited domestic demand outside existing supply chains.
