Senra builds software-guided wire harnesses for aerospace, defense, and other advanced hardware programs. Its $65 million Series B is a bet on modernizing wire harness manufacturing. Many factories still rely on PDFs, spreadsheets, and manual bench-top work. Senra believes the process can become faster, cleaner, and more traceable. The company was founded in 2023 by former SpaceX engineers Jordan Black and Benjamin Shanahan. Black got the idea after encountering wire harness bottlenecks while helping scale Starship production. As vehicles become smarter, their internal wiring becomes more critical. Even a tiny process mistake can cause major schedule delays.
What does Senra’s wire harness manufacturing platform do?
Senra isn’t just another contract manufacturer with nicer branding. It combines a browser-based harness design tool and internal factory software with actual production capacity. A customer can move from concept, quote, engineering review, procurement, build planning, assembly, and quality control inside one system instead of bouncing between disconnected teams and files. That’s the core pitch: fewer handoffs, fewer surprises, and a design that’s ready for the floor when it leaves engineering.
Its software platform is called Amp. It’s an ITAR-compliant cloud tool that gives engineers manufacturing feedback while they’re still designing the harness and captures high-fidelity data at the design stage. That data becomes a digital thread the factory can actually use. The company also offers digital twin conversion and design-for-manufacturability support. It also does 3D and 2D formboard creation, plus supply-chain guidance on piece parts.
The back half matters just as much. Amp uses GovCloud-hosted AI to read bill-of-materials data from messy, unstructured files and speed up aerospace RFQs by an order of magnitude. It then feeds that into procurement, warehousing, and kitting workflows. Senra says its software creates work instructions 5x faster with templated operations. It also generates a first-pass build plan based on the engineering drawings.
On the floor, the system tracks every crimp, connection, and shipped serial. Senra says real-time process enforcement and end-to-end traceability help it hit 99%+ first-pass yield, while FactoryOS converts design data into build instructions and machine programs. Before that kind of setup, customers were often stuck in weeks of email back-and-forth just to clarify what should be built. Senra’s pitch is that design and production finally speak the same language.
Who founded Senra and why start it?
The company started with a very specific factory headache
Black and Shanahan founded Senra in 2023 after working together at SpaceX. Black had been the manufacturing development engineer for wire harnessing, building processes for Dragon, Falcon, and spacesuit products before becoming the youngest manager in SpaceX Avionics R&D. He’s said that while scaling Starship-related production, he flew around the world auditing harness suppliers and kept finding the same thing — a business that still looked frozen in the Cold War, with wooden tables and manual workflows doing mission-critical work.
That frustration became the company. Senra began building harnesses out of Black’s apartment within weeks of incorporation. The name is a joke with a point: it’s “harness” backwards, minus the “h” and “s,” because Black says the company is trying to take the “horseshit” out of harnesses.
The founders actually fit the problem
Black’s background is unusually hands-on for a software-heavy manufacturing startup. Before SpaceX, he started as a technician fixing roller coasters at the Santa Monica Pier and had internships at Ford and Enerpac. That gives him the kind of shop-floor bias Senra needs, because the company’s thesis is that the answer isn’t just prettier design software — it’s software that respects how hard physical production really is.
Shanahan brings the other half. He studied neuroscience at Brown, worked as a software engineer at BrainGate, then joined NeuroPace, where he helped productionalize machine-learning workflows and built visualization-heavy applications. At SpaceX, he worked on the company’s internal purchasing system and Starlink’s manufacturing execution system. He also worked on telemetry infrastructure for satellites, launches, and engine tests. If Senra is trying to turn a craft-heavy process into a systematized one, that mix of software, operations, and hardware experience makes a lot of sense.
Traction, facilities, and the round itself
Senra’s product is no longer a concept. Amp is in public beta, the company has a 15,000-square-foot Redondo Beach facility, and it opened an 80,000-square-foot site in Cypress that expanded its production footprint by 5x. Black says Senra is currently producing about 1,000 harnesses a month across 2 factories and wants to reach 10,000 a month in 2027.
Customer disclosure is still selective, but the company says its work spans submarines and maritime systems, land-based defense platforms, launch vehicles, and satellites. Earlier this year, Senra also said 8 Fortune 500 manufacturers were already customers. It also said it had partnerships across top aerospace, defense, automotive, industrial, and healthcare programs, including Anduril.
Now the money. Senra announced its $65 million Series B on July 15, 2026. Lowercarbon Capital and Interlagos co-led the round, with participation from General Catalyst, Sequoia Capital, Andreessen Horowitz, Founders Fund, Dylan Field, CIV, 8VC, The Friedkin Group, Jaws Estates Capital, Sozo Ventures, and Alumni Ventures. The company said total funding has now topped $112 million; before this, it had raised a $25 million Series A led by Dylan Field and CIV. Senra plans to use the new capital to expand with a third manufacturing facility and keep building out its platform.
How does Senra compare in wire harness manufacturing?
The legacy alternative is still the real competitor. A lot of harness work gets done with custom drawings, spreadsheets, email threads, tribal knowledge, and skilled technicians following instructions that may or may not be standardized. That works until volume rises, engineering changes pile up, or one bad material choice shows up late in the program.
Then there are the software incumbents. Siemens Capital, Zuken E3, and Cadonix Arcadia all sell harness design and manufacturing tools. They automate validation and formboard creation. They also handle connectivity checks, manufacturing documentation, and in some cases digital build instructions. Those products aren’t fake competition. They’re serious, established systems.
Senra is taking a different swing. Instead of stopping at software, it owns the factory too. That means it can push design rules upstream, translate them straight into procurement and work instructions, and use the same data on the production line. That full-stack model is probably what investors are buying here — not just better CAD, but tighter control over cost, speed, and traceability in sectors where a late harness can delay an entire aircraft, satellite, or weapons program.
Why does this $65M Senra round matter?
Because Senra isn’t trying to fund a cleaner dashboard. It’s trying to build actual industrial capacity around a part that almost nobody outside manufacturing talks about, even though it sits inside nearly every advanced machine. The company has already brought in former SpaceX CIO Ken Venner as chief technology and product officer. That suggests this round is as much about operational scale as software polish.
And the stakes are real. In 2023, Boeing’s Starliner program had to redo its wiring system after flammable tape was found in the harness setup, causing a costly delay. That’s why Black keeps coming back to standardization, traceability, and engineering-change control. A harness mistake isn’t glamorous. It’s just expensive.
This round also sharpens Senra’s strategy. Black has said he follows the “Elon principle” that “automation is last,” which is a useful reality check in a sector that loves promising robot-first miracles. Senra isn’t pretending robots have solved wire handling yet. It’s starting with software, process control, and technician training — including what Black describes as the only federally certified wire harness training program. Then it layers in more automation. That’s less flashy, but it’s probably the only credible path to scaling from 1,000 units a month to 10,000 without wrecking quality.
How big is the wire harness manufacturing market?
Big enough that investors don’t need Senra to own the whole thing for this to matter. A World Bank report published in 2024 put the global wire harness market at roughly $50 billion and said it is expected to grow at about 3% CAGR over the next decade. The same report noted that vehicle electrical and electronic systems were valued around $250 billion in 2023, with some estimates pointing to $460 billion by 2030.
That trend helps explain the timing. As vehicles, aircraft, satellites, and defense systems get more electrified and more sensor-heavy, harnesses stop being simple bundles of wire and start becoming dense, failure-sensitive subsystems. The World Bank also notes that while cutting and crimping can be automated, assembly is still labor-intensive. Siemens makes a similar point from the software side, warning that an aging workforce and the loss of experienced workers are already creating launch risks.
So yes, Senra is going after a niche. But it’s the kind of niche that quietly expands as everything else gets smarter.
What should you watch next from Senra?
The question isn’t whether wire harness manufacturing needs an upgrade. It obviously does. The question is whether Senra can turn a strong founder story and a lot of fresh capital into repeatable output at real industrial scale — especially once a third factory comes online and more customers start treating Amp as a design system, not just a vendor add-on. If that happens, Senra won’t just be a better harness shop. It’ll be infrastructure.
