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

Senra, a startup founded by ex-SpaceX engineer Jordan Black and Benjamin Shanahan, raised a $65 million Series B to modernize wire-harness manufacturing for aerospace, defense, and other vehicle markets. The company uses proprietary software and digital-twin workflows to standardize materials tracking and engineering changes, aiming to reduce costly errors in a process still dominated by manual labor and Cold War-era production methods. The round was co-led by Lowercarbon and Interlagos, with participation from major venture firms including General Catalyst, Sequoia, Andreessen Horowitz, and Founders Fund. Senra says it already produces about 1,000 harnesses per month across two factories and plans to scale to 10,000 monthly in 2027. The funding highlights growing investor enthusiasm for U.S. manufacturing and defense-industrial infrastructure, especially as mistakes in wiring can cause major program delays and costly rework, as seen in Boeing’s Starliner issues.
