Isembard

Isembard is a London software-first manufacturing company that runs a distributed network of AI-powered factories producing high-precision metal components for aerospace, defence, energy and robotics. Founded in October 2024 by Alexander Fitzgerald (ex-HM Treasury adviser and founder of broadband startup Cuckoo), it combines modular factory builds and a franchise model with MasonOS, its AI-native operating layer that automates quoting, CAD/CAM, procurement, scheduling, quality assurance and logistics across 5-axis CNC and robotic cells. Factories hold certifications such as ISO 9001, Cyber Essentials and JOSCAR. Isembard raised a $9 million seed in April 2025 and a $50 million Series A in March 2026 to expand toward about 25 facilities by end-2026 across the UK, US, Germany, France and Ukraine, serving defence and autonomy startups as well as established OEMs—sometimes managing end-to-end supply chains.
