Founded in 2024, Isembard produces high-precision components and assemblies for industries such as aerospace, defence, and energy.

Leveraging advanced CNC machining and automation, the company enables hardware startups and industrial firms to move rapidly from prototype to production, bypassing delays typical of traditional supply chains.

Its factories are powered by MasonOS, Isembard’s proprietary software that manages quoting, scheduling, production, and quality control.

By combining precision machining with a software-driven factory network, Isembard aims to accelerate manufacturing, strengthen Western industrial supply chains, and reduce reliance on global supply networks.

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, adds: “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.”
