Senra Secures $65M to Modernize Industrial Wiring

Wire harnesses—the intricate electrical nervous systems found in rockets, submarines, and defense vehicles—have long been assembled by hand on wooden tables using methods that have barely evolved in decades. Black, who managed the scaling of wire harnesses for SpaceX’s Starship program, co-founded Senra in 2023 to address the fragility of this process. The Series B round, co-led by Lowercarbon and Interlagos, includes backing from Sequoia Capital, Andreessen Horowitz, and Founders Fund, signaling strong investor interest in the revitalized U.S. manufacturing sector.

Rather than attempting to fully automate away human labor, which remains essential due to the complexity of handling wires, Senra focuses on software-driven standardization. Its proprietary platform, Amp, creates a digital twin of every assembly to guide technicians. This approach aims to prevent disasters like the one Boeing faced in 2023, when flammable tape used in its Starliner spacecraft forced a costly redesign. Currently producing 1,000 harnesses monthly across two factories, the startup plans to reach a capacity of 10,000 units per month by 2027.
