Critical Source Technologies helps hardware startups transform prototype wiring into production-ready wire harnesses for scalable, reliable manufacturing.
Our Craft
Wire bundles engineered and loomed for repeatable, production-grade builds.
Precise pin mapping and connector selection built to spec, every time.
Routing diagrams and drawing packages manufacturers can quote and build from.
What We Do
We help hardware startups take prototype wiring and turn it into a harness designed to be built at volume.
We review your prototype wiring and re-engineer it for repeatable, cost-effective production before you commit to tooling.
Production-grade drawings, wire lists, and BOMs built to IPC/WHMA-A-620 standards that manufacturers can quote and build from.
We bridge the gap between a hand-built proof of concept and a harness that's ready for repeatable, scalable manufacturing.
We help you identify, vet, and qualify harness manufacturers that match your volume, quality, and budget requirements.
We identify design changes that reduce unit cost and assembly time as your production volume grows.
Guidance on testing, inspection criteria, and industry standards so your harnesses are reliable from the first build.
Why Choose Us
We combine engineering precision with a startup-first approach on every engagement.
We speak the language of early-stage hardware teams and understand the constraints of moving fast on a limited budget.
We specialize in the exact transition point most startups struggle with: going from one-off wiring to a repeatable harness.
Every design undergoes rigorous internal checks before delivery to ensure zero defects at handoff to manufacturing.
We become an extension of your engineering team — available on-site or remote through every phase of the transition.
