When Senra CEO Jordan Black was an engineer at SpaceX, he noticed that the wire harnesses used in vehicles and rockets hadn’t changed much since the Cold War. With this in mind, Black co-founded Senra to bring modern automation to these ancient crafts.

The company has just raised $65 million from big names like General Catalyst and Sequoia Capital to develop a proprietary software platform called Amp, which standardises inputs throughout the wiring process and produces digital twins for technicians. While handcrafting remains an essential part of the process, Senra aims to modernise this traditionally manual work.

Black points out that wire harness disasters can have catastrophic consequences, citing Boeing’s Starliner spacecraft issue as a prime example. He argues that automation is key to preventing such incidents in the future by allowing for better tracking and management of changes within the system.

Serna produces 1,000 wire harnesses each month across two factories, with plans to increase production to 10,000 per month by 2027. The company’s name is a play on words, reversing 'harness' minus 'h' and 's', as Black claims they've ‘tackled the horsesh*t out of harnesses’.

Senra isn’t just about making wires; it's about ensuring that vehicles from submarines to rockets are safer and more reliable. As one can imagine, such innovations could have a profound impact on sectors ranging from aerospace to automotive.
