Isembard unlocks £37m Series A led by Union Square Ventures to manufacture high-precision components for critical industries

Isembard manufactures high-precision components for aerospace, defence, energy and robotics companies. It operates its own and franchisee factories using proprietary software that integrates quoting, scheduling, supply chain, manufacturing, quality control and delivery.

Isembard, a high-precision component manufacturing startup, has raised £37 million in Series A funding led by Union Square Ventures, with participation from Tamarack Global, IQ Capital, Notion Capital, CIV, and angel investors Alex Bouaziz, Andrei Danescu and Matt Briers. The capital will accelerate plans to open 25 factories by the end of 2026, expand engineering teams and launch into Germany, France and Ukraine.

Component manufacturing is a market worth $1.8 trillion 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 driven by re-shoring and spending increases on critical industries.

Isembard manufactures high-precision components for many of the world’s most demanding customers. It operates its own and franchisee factories, differentiated by proprietary software and AI system MasonOS, which runs them. MasonOS integrates quoting, scheduling, supply chain, manufacturing, quality control and delivery into a single operating layer that automates and continuously optimises factory performance.

The business 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 or convert existing businesses into an Isembard factory, expanding manufacturing capacity while preserving local ownership across the United Kingdom, United States and Europe.

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.

Alexander Fitzgerald, Founder & CEO

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.
