Senra, a startup founded by a former SpaceX engineer, announced a $65 million Series B round in July 2026 to bring software-driven manufacturing to wire harnesses — the internal electrical cabling used in rockets, satellites, submarines, and other vehicles.
The round was co-led by Lowercarbon and Interlagos, with participation from General Catalyst, Sequoia Capital, Andreessen Horowitz, and Founders Fund, among others.
CEO Jordan Black founded Senra in 2023 alongside co-founder Benjamin Shanahan. Black’s background includes scaling wire harness production at SpaceX to support the Starship rocket program, during which he visited wire harness manufacturers around the world. “It really hasn’t changed since the Cold War era of wooden tables [and] manual processes,” he told TechCrunch.
Senra’s approach does not aim to replace human technicians — wire manipulation remains difficult to automate and training data is scarce — but instead uses software and selective automation to standardize and track the manufacturing process. Its proprietary platform, called Amp, produces a digital twin to guide technicians and standardizes inputs throughout production. The company also operates what Black describes as the only federally certified wire harness training program.
The company currently produces 1,000 wire harnesses per month across two factories and plans to scale that to 10,000 per month by 2027. Customers, which Black did not name, span submarines, land-based defense systems, launch vehicles, and satellites.
Black cited a 2023 incident involving Boeing’s Starliner spacecraft — where wiring held together with flammable tape required an expensive overhaul — as an example of why tighter standards and integrated software tracking matter. “Having it all in the same software is probably the most important thing, because it’s all the little inputs that happen that can make a catastrophic change down the road,” he said.
Senra is positioned to benefit from increased U.S. investment in domestic manufacturing and the defense industrial base.
