HarnessHive

HarnessHive is a highly specialized industrial software product: an AI-native design platform for wire harness engineers in industries such as automotive, construction machinery, and aerospace.

Traditional harness design requires moving data back and forth between schematics, wiring diagrams, bills of materials, and 1:1 wiring boards. HarnessHive puts all of these into a single real-time document, so when you change one place, the rest updates automatically. Teams can collaborate online without installing any software. The built-in AI assistant provides guidance at every step, such as checking whether connections are consistent and helping generate BOMs.

It offers a 14-day free trial with no credit card required, and you can also book a demo. The target audience is fairly narrow, but for small wire harness factories and design teams still cobbling together workflows with Excel and legacy CAD, it should be a clear productivity win.
