Manufacturing is so back, baby. Well, at least if AI and defense are involved.
Yesterday, UK-based advanced manufacturing startup Isembard announced it has raised a $50M Series A round led by Union Square Ventures to accelerate its plan to open 25 factories by the end of the year.
CEO Alexander Fitzgerald told Tectonic that most of that build-up will be in the US.
Are you feeling the reindustrialize vibes yet?
Build baby build: Between Hadrian’s $260M round in July (and another in January boosting its valuation to $1.6B), Divergent’s $290M Series E at a $2.3B valuation in September, and UNION’s $51M seed round last May, advanced manufacturing is having a bit of a moment.
Isembard is no exception—and they’ve got some big backers joining the cap table.
The $50M funding round was led by Union Square Ventures, an early backer of Twitter and Coinbase, with participation from new investors including Tamarack Global and IQ Capital, alongside existing investors Notion Capital and CIV.
Speedrun: Named for the great British engineer Brunel, Isembard was founded in 2024 and raised a £7M ($9.4M) seed round last April.
The company has a unique model—they have their own factories, but they’re also on a mission to become what Fitzgerald called “McDonald’s as a manufacturing company.” Essentially, they want to open up factory franchises across the US and Europe, with a focus on the small family-owned businesses that are increasingly closing up shop.
“We find franchisees who have a bit of capital and experience, and we enable them to set up Isembard factories by giving them our technology and our brand, customers, and accreditations, especially in these critical industries,” Fitzgerald said. “From a franchisee perspective, there’s never been a better time to attract the best engineers and operators to solve some of the hardest problems for customers.”
Each Isembard facility houses a range of component-manufacturing equipment, including Computer Numerical Control (CNC) machines—which carve and cut material from solid metal blocks or sheets—alongside sheet-metal forming and injection-molding systems. That allows them to pump out a wide range of parts for everything from space-bound rockets to unmanned air, sea, and land systems, as well as jet engines.
The numbers, Mason: Another ingredient in Isembard’s secret sauce is their in-house AI-driven manufacturing software, MasonOS:
- The software automates the manufacturing workflow, starting with the upload of a 3D model of the component.
- MasonOS then provides quotes for the material cost and lead time, produces a prototype, and gets the machines to optimize production across factories to scale.
And even before this latest raise, Isembard has been on quite the run.
- They opened up their US headquarters in Texas last July, followed by another factory in Missouri.
- On the defense side, their customers include Texas-based counter-drone startup Allen Control Systems, Portuguese drone-maker Tekever, German unmanned ground vehicle company ARX Robotics, and a small startup called Anduril, among others.
- They now have six factories—three in the US and three in the UK—and have plans to expand into Germany, France, and Ukraine in the near future, on top of their 25-factory target for 2026.
With the fresh capital in hand, the big focus is getting their tech into as many factories as possible—and they’re betting that franchise model will make it happen.
“Often the best kind of businesses are hard to put in a box initially, and then they create their own box around them,” Fitzgerald said. “Our whole thesis is that this is actually something new, in terms of building a way to actually scale up manufacturing for the West.”
