The Problem

Traditional harness manufacturing is broken.

Long quote times. Longer lead times. Rigid manufacturing. Unresponsive suppliers. You send a drawing into a black box and wait. Meanwhile, your prototype timeline slips.

Founded in 2024, we're rethinking how wire harnesses are made by combining automation with rapid turnaround so hardware teams can move as fast as their ideas.

We're building the solution.
