British manufacturing startup Isembard has raised £7 million (~$9 million) in seed funding to accelerate its mission of reshoring high-precision manufacturing across the West.
The round was led by Notion Capital, with backing from 201 Ventures, Basis Capital, Material Ventures, Neverlift Ventures, NP-Hard Ventures, and angel investors including Andreas Klinger (EU Inc) and Joshua Western (SpaceForge).
As geopolitical tensions and supply chain disruptions mount, Isembard is positioning itself as a modern industrial solution—offering distributed, software-driven production of mission-critical components for industries like aerospace, defense, and energy.

Precision Manufacturing, Reimagined
Founded by Alexander Fitzgerald, Isembard aims to rebuild local manufacturing capacity by deploying a network of smaller, distributed factories powered by its proprietary operating system, MasonOS. These sites are designed to handle custom, high-spec production runs for clients who need quality and speed—but without the time or capital to invest in their own facilities.
“If you’re building something like a drone, you send us your CAD file, we quote it, manufacture the parts, and ship it out. Sometimes, we’ll even handle the final assembly,” said Fitzgerald.
The company launched its first operational site in London earlier this year and plans to scale across other Western markets, including potential expansion into North America, Australia, and New Zealand.
Software at the Core
At the heart of Isembard’s model is MasonOS, a full-stack platform that automates quoting, scheduling, supply chain management, and machine coding—functions that are still paper-based or reliant on outdated software in many legacy factories.
“We’re solving the bottleneck with a software-first approach that’s modular, fast, and capital-light,” Fitzgerald said.
Rather than mimic large U.S. players like Hadrian, which raised $216M to build centralized superfactories, Isembard is taking a leaner, decentralized route—operating smaller units with uniform tech and operational standards to achieve scale.
Targeting Strategic Industries
Isembard’s go-to-market strategy is focused on sectors that demand security, precision, and speed:
- Defense
- Aerospace
- Energy and critical infrastructure
While Fitzgerald declined to name specific clients, he noted growing traction with defense customers and fast-scaling startups, and said conversations are underway with major contractors and public sector agencies.
A Mission Rooted in Resilience
The company’s name—a nod to Isambard Kingdom Brunel, the legendary British engineer—signals its industrial ambition. But Fitzgerald also draws personal inspiration from national service: a longtime military reservist, he sees Isembard as part of a broader mission to rebuild Western resilience in core industries.
“We want to help solve reindustrialization for the West,” he said.
Looking Ahead
With just 12 employees, Isembard has operated lean by design—bootstrapped until this round using proceeds from Fitzgerald’s previous exit (he sold broadband startup Cuckoo to Giganet in 2022). Now, with fresh capital, the company plans to:
- Launch additional factory units across Europe
- Expand its engineering and operations teams
- Enhance MasonOS for broader industrial use
- Deepen partnerships across defense and energy verticals
As supply chain independence becomes a national priority, Isembard’s distributed, automation-first model offers a compelling new playbook for reshoring precision manufacturing at scale—without the delays, cost, or complexity of the past.
