Isembard, a London-based precision manufacturing company, has raised €43 million ($50 million) in a Series A funding round to expand its network of software-driven factories and scale operations across Europe.
The round was led by Union Square Ventures, with participation from Tamarack Global and IQ Capital, as well as existing investors Notion Capital and CIV. The funding comes less than a year after the company’s seed round and will support new factory openings, engineering recruitment, and international expansion.
What The Company Does
Founded in 2024 by Alexander Fitzgerald, Isembard develops high-precision components and assemblies for sectors including aerospace, defence, and energy.
The company operates manufacturing facilities equipped with advanced CNC machining systems and automation technologies designed to produce complex industrial parts with high accuracy. These components are typically used in industries that require strict engineering standards and reliable supply chains.
Isembard’s approach combines physical manufacturing infrastructure with proprietary software. Its internal platform, MasonOS, manages key aspects of factory operations such as quoting, production scheduling, workflow coordination, and quality control.
By digitizing these processes, the company aims to reduce inefficiencies commonly found in traditional manufacturing operations. The system allows production facilities to coordinate manufacturing tasks more efficiently while maintaining quality and traceability.
Isembard’s platform is also designed to support hardware startups and industrial companies that require rapid transitions from prototype development to full-scale production.

Market Context / Industry Background
Manufacturing supply chains in sectors such as aerospace and energy are increasingly under pressure to become more resilient and geographically diversified. Global disruptions in recent years have exposed vulnerabilities in extended supply networks that rely heavily on overseas manufacturing.
In response, many governments and industrial companies are exploring ways to strengthen domestic and regional production capacity, particularly in industries tied to national infrastructure and security.
At the same time, software is playing a growing role in manufacturing operations. Digital factory management systems are being used to coordinate production processes, track component quality, and optimize the use of industrial equipment.
Companies developing integrated manufacturing platforms are attempting to combine advanced machining technologies with digital management systems in order to improve efficiency and reduce production lead times.
By integrating software with distributed manufacturing facilities, Isembard aims to create a more flexible production network capable of supporting both startups and established industrial companies.
Founder / Investor Commentary
Isembard founder and CEO Alexander Fitzgerald said the company’s mission is to modernize industrial manufacturing while strengthening Western production capacity.
“Manufacturing is the origin of our security, prosperity and sense of purpose as nations,” Fitzgerald said.
“This Series A enables us to open more factories, invest in MasonOS, support exceptional franchisees and recruit the best engineers across Europe and the United States. Our mission is to forge industrial acceleration.”
Rebecca Kaden, Managing Partner at Union Square Ventures, said the company’s approach rethinks how modern manufacturing businesses can be operated.
“Isembard is redefining the process of owning and running a factory,” Kaden said.
“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.”
Growth Plans / Use Of Funds
Isembard plans to use the Series A funding to expand its manufacturing footprint by opening 25 factories by the end of 2026.
The company will also invest in the continued development of MasonOS, strengthening the platform’s ability to manage factory operations across a distributed network of facilities.
Geographically, Isembard intends to launch operations in additional European markets, including Germany, France, and Ukraine.
Part of the funding will also support recruitment of engineering talent as the company expands both its manufacturing capabilities and software platform.
In addition to institutional investors, the round included angel investors such as Deel founder and CEO Alex Bouaziz, Dexory Robotics founder and CEO Andrei Danescu, and former Wise CFO Matt Briers.
