Component manufacturing is a trillion-dollar-a-year market, but it’s an area dominated by small, often family-run businesses that are rapidly dwindling as the owners retire.
Isembard is a UK startup that manufactures high-precision components, operating both its own and franchisee factories. It has also built its own AI-driven proprietary software platform, MasonOS, which runs them.
It’s now raised $50 million in a Series A funding, within a year of its Seed round, and plans to open 25 factories by the end of 2026, while launching into Germany, France, and Ukraine.
The round was led by New York-based Union Square Ventures. Existing investors Notion Capital and CIV joined new investors Tamarack Global and IQ Capital. Angel investors include Alex Bouaziz (Founder and CEO of Deel), Andrei Danescu (Founder and CEO of Dexory Robotics), and Matt Briers (former CFO of Wise).
The company says that MasonOS integrates quoting, scheduling, supply chain, manufacturing, quality control, and delivery “into a single intelligent agentic operating layer, automating and continuously optimising factory performance.”
How it works with franchisees is that it identifies existing component makers and gives them its technology, brand, engineering standards, and access to customer demand.
This effectively refreshes these pre-AI-era companies, giving Isembard the kind of scale its platform wouldn’t otherwise have. It also means more sovereign industrial capability across the countries in which it operates.
“Everything in the world is made up of different manufacturing processes,” says Isembard founder and CEO Alexander Fitzgerald. “But the word supply chain hides a long tail of tens of thousands of small businesses.”
Those small businesses are increasingly under pressure as owners retire, capacity shrinks, and Western industrial demand rises again in sectors such as aerospace, energy, robotics, and defence.
“The real existential threat now,” Fitzgerald says, “is that just as demand is rising in the West, the number of machines that can actually make those components is declining.”
Many component factories today are small operations with a handful of machines and fewer than twenty employees. In the US alone, there are around 40,000 CNC machine shops with an online presence, Fitzgerald says, with even more across Europe.
“These businesses might have 10 or 15 machines and maybe 20 people,” he explains. “But collectively they’re the ones making the individual parts that go into everything from cars to satellites.”
Historically, large companies sourced those parts from networks of small suppliers. Over time, however, some production moved overseas while many Western machine shops aged out.
Isembard’s solution is to combine AI software, new factories and a franchising model to rebuild that capacity. The company began with its own factory in Park Royal in northwest London, using it as a testbed to develop its technology and manufacturing processes.
“We started with our own factory developing the software to run that factory,” Fitzgerald says. “And now we’re scaling the number of factories.”
“People think the word factory means something huge,” he says. “But the minimum viable factory is actually two CNC machines, four walls, power, and a few other pieces of equipment.”
According to Fitzgerald, a new factory can often be operational within two to three months of signing a franchise agreement. The approach allows Isembard to scale manufacturing capacity much faster than if it owned every facility itself.
It also allows the company to modernise older machine shops with its software and processes, effectively upgrading pre-AI manufacturers into part of a coordinated production network.
At the centre of the model is MasonOS, Isembard’s proprietary AI-driven software platform. Manufacturing, Fitzgerald argues, is fundamentally an orchestration problem.
“You need to manage designs, track materials, schedule jobs across multiple machines and deliver within strict quality frameworks,” he says.
Historically, manufacturers relied on separate software tools, or manual processes, to manage these steps.
“MasonOS collapses all of those different systems into a single operating layer across the whole factory,” explains Fitzgerald.
The platform integrates quoting, scheduling, supply chains, manufacturing, quality control, and delivery into one system. Crucially, it also connects multiple factories together.
“It doesn’t just optimise one factory,” Fitzgerald says. “It enables demand to be orchestrated across multiple factories. Those two things have never really been connected before.”
That network effect allows Isembard to deliver parts faster and distribute work across its manufacturing network. The company is also planning to open operations in Ukraine, where reconstruction and defence demand are expected to create long-term industrial opportunities.
In a statement, Rebecca Kaden, Managing Partner at Union Square Ventures, added: “Isembard is redefining the process of owning and running a factory. By embedding deep operational expertise into an agentic OS, MasonOS lowers the barrier to operating high-performance manufacturing businesses and enables a networked, capital-efficient path to scale. At a moment when demand for advanced manufacturing is accelerating, and interest in SMB ownership is rising, Isembard brings both forces together.”
