Isembard has announced that it has raised $50m in Series A funding, accelerating plans to open 25 factories by the end of 2026.
The funding will also allow the company to expand its engineering teams while launching into Germany, France and Ukraine.
Isembard manufactures high-precision components for aerospace, defence and robotics. The company operates its own and franchisee factories, which is run by its proprietary software and AI system, MasonOS.
MasonOS integrates quoting, scheduling, supply chain, manufacturing, quality control and delivery into a single intelligent agentic operating layer, automating and continuously optimising factory performance.
Component manufacturing is a market worth $1.8tn a year. Yet small businesses account for 95% of production and they are rapidly disappearing. The average owner is over 65 years old and 40% plan to retire within five years.
This erosion of industrial capacity is colliding with surging demand from aerospace, defence, energy and robotics companies given re-shoring and spending increases on critical industries. The company says that without decisive action, the widening gap between supply of factories and demand from customers risks hollowing out the industrial base of Europe and North America.
Isembard identifies operators – from manufacturing, the military, franchising and the wider economy – and equips them with its technology, brand, engineering standards and access to customer demand. Franchisees can launch new Isembard factories from the ground up or convert existing businesses into an Isembard factory.
This approach enables rapid expansion of high-quality manufacturing capacity while preserving local ownership and strengthening sovereign industrial capability across the United Kingdom, United States and Europe.
Alexander Fitzgerald, Founder and CEO of Isembard, said: “Manufacturing is the origin of our security, prosperity and sense of purpose as nations. 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: “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. We’re excited to partner with Alexander and his team as they expand access to factory ownership and rebuild industrial capacity across the West.”
