ProvenMetal: PCB boards delivered in 5 days, made in the USA
Original: Launch HN: ProvenMetal (YC S26) delivers circuit boards in days instead of weeks
Why This Matters
Faster domestic PCB supply chains are critical for US hardware startups and defense-adjacent customers facing long lead times.
YC S26-backed startup ProvenMetal offers printed circuit board (PCB) fabrication and assembly with a 5-day fastest turnaround, fully domestic US supply chain, end-to-end quality tracking, and flexible pricing based on delivery speed.
ProvenMetal is a Y Combinator S26-backed startup offering fast PCB (printed circuit board) manufacturing services, with a minimum turnaround of 5 days — compared to the industry-standard 4-week lead time. The company manages the full build process in-house: sourcing parts from vetted US suppliers, verifying them against the customer's BOM (bill of materials), running fabrication and assembly through domestic partners, and conducting testing before shipment. Every order ships with a complete quality record including parts traceability, process data, and inspection results. Customers can choose between a fast 5-day turn or a slower, lower-cost option depending on schedule. For customers requiring full domestic production, ProvenMetal offers a supply chain that never leaves the US. The company also claims that revision orders turn around faster, as they build from the previous revision as a starting point. Ordering is now open via their website, where customers submit design files and receive a firm quote with a confirmed ship date before committing.
