A SpaceX vet raised $65M to pull wire harnesses out of the Cold War era

Jordan Black, the CEO of Senra and a former engineer at SpaceX, has turned his expertise into a groundbreaking venture aimed at modernizing the production of wire harnesses. These essential components, comprising the internal electrical cabling for vehicles ranging from rockets to cars, have largely remained unchanged since the Cold War era. Black’s efforts focus on transforming the traditional, labor-intensive methods that rely on skilled technicians assembling these harnesses by hand. Founded in 2023 alongside co-founder Benjamin Shanahan, Senra has successfully raised $65 million in a Series B funding round, co-led by Lowercarbon and Interlagos. This round also saw participation from notable investors like General Catalyst, Sequoia Capital, Andreessen Horowitz, and Founders Fund. Rather than eliminating human involvement in the crafting of wire harnesses, Senra is leveraging software tools and automation to enhance the efficiency of these processes. The startup is positioned to benefit significantly from the ongoing investment surge into U.S. manufacturing, particularly within the defense sector. While Black was unable to disclose specific clients, he indicated that Senra’s customers include manufacturers of submarines, defense vehicles, launch systems, and satellites. A recent incident involving Boeing’s Starliner spacecraft, which faced costly delays due to unsafe wiring practices, underscores the critical need for improved standards in wire harnessing. To mitigate such risks, Senra is implementing automated systems to monitor material usage and engineering modifications. Black emphasized the importance of consolidating data within a single software platform to prevent minor oversights that could lead to major failures. The company employs its proprietary software, Amp, to standardize inputs throughout the wiring process, creating a digital twin that assists technicians trained in what Black describes as the only federally certified wire harness training program. As Senra continues to grow, it aims to further automate its production processes. Black referenced a principle from Elon Musk stating, 'automation is last,' highlighting that while the company is actively pursuing automation, the foundational standardization that enabled SpaceX to scale its rocket production remains a priority. Currently, Senra produces 1,000 wire harnesses monthly across two factories, with ambitious plans to ramp up production to 10,000 per month by 2027.
