Backed by Combinator

We build circuit boards fast.

One team sources every part, assembles and tests your boards in the US, and ships a full quality record with every order.

Turn Times

Speed you can plan around.

A four-week turn breaks your schedule. Ours run five to seven days.

Phase 01Day 0–2

Source & verify

We buy every part against your BOM and verify it before the build starts.

Phase 02Day 2–5

Fabricate & assemble

We run fab and assembly with vetted partners we manage ourselves, fully domestic when you need it.

Phase 03Day 5–7

Test & ship

We test every board and ship it with a full quality record.

Common questions

Standard turns run seven days; five at the quickest. Your quote shows the exact ship date before you commit.

Then we build the other way: a longer turn at a lower price. You pick the tradeoff on every order.

No. We start from your last revision, so later revs come back faster.

Full Accountability

One team owns the whole build.

ProvenMetal sets the build plan, manages each facility, and remains accountable from the first sourcing decision through final test and delivery.

Parts stay controlled.

Sourced or consigned, parts are received against the BOM, kept lot-traceable, and handled under MSL and ESD controls.

Testing is planned up front.

Acceptance criteria and fixtures are agreed before production and available at the test site, so failures can be reworked before shipment.

One team owns the outcome.

We manage sourcing, fabrication, assembly, inspection, test, and delivery, then ship the build record with your boards.

How It Works

One partner, start to finish.

[01]

SOURCE

Send your files. We source and verify every part to fit your spec and budget.

[02]

BUILD

We run fabrication and assembly across vetted partners, fully domestic if you need it, and manage the whole build.

[03]

VERIFY

AOI and X-ray on every board, plus functional test, bring-up, and firmware loading when you need it. Full quality record ships with the order.

Self-serve order intake

Upload your design. Get a build plan.

Upload Gerbers, drill files, your BOM, and placement data without creating an account. We show you what we found, then return a quote with the build scope, ship date, and any setup or NRE before you approve it.

Automated DFM review uses Anthropic in zero-retention mode. A manual review with no external model processing is available. Review data handling.

Domestic build · on request

America builds again.

Need it fully domestic? We run the entire build inside a US supply base we manage. Say the word and your boards never leave the country.
