Isembard is a UK- and US-based advanced manufacturing company building a distributed network of software-powered precision factories for critical industries including aerospace, defence, space, satellites, drones, nuclear energy, and motorsport. Founded in 2024 by Alexander Fitzgerald and named after engineer Isambard Kingdom Brunel, the company runs its factories on MasonOS, a proprietary AI-powered operating system that manages quoting, scheduling, production, and quality control across its factory network. Its model reshores high-precision component manufacturing closer to home to address supply-chain vulnerabilities in the Western industrial base, scaling from prototypes to production and offering factory franchise opportunities. Isembard has raised a Series A led by Union Square Ventures and operates factories across the UK, US, France, and Germany. There is no public developer API; MasonOS is an internal software platform, so this profile captures the company's identity and web surface rather than an API.
