Industrial startup Isembard bags €43 million to scale software-powered factories for aerospace and energy sectors

London’s Isembard today announced that it has raised €43 million ($50 million) in Series A funding, less than 12 months after its Seed round in order to open 25 factories by the end of 2026, expand its engineering teams while launching into Germany, France and Ukraine.

The round was led by Union Square Ventures. New investors Tamarack Global and IQ Capital joined the round alongside existing investors Notion Capital and CIV. Angel investors include Alex Bouaziz (Founder and CEO of Deel), Andrei Danescu (Founder and CEO of Dexory Robotics) and Matt Briers (former CFO of Wise).

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.”

Recent funding activity reported by EU-Startups highlights growing investor interest in advanced manufacturing infrastructure, factory software and industrial automation across Europe.

In Switzerland, SAEKI raised €6.4 million in Seed funding to develop autonomous factories and automate digital manufacturing workflows. Also in Switzerland, Forgis secured €3.8 million in pre-Seed funding to automate industrial machines and increase production throughput using physical AI. In Germany, Cologne-based United Manufacturing Hub raised €5 million to develop an open-source data infrastructure layer for modern factories.

In industrial operations software, Cerrion secured €15.6 million in Series A funding to scale an AI video-agent platform designed to reduce factory downtime and improve operational efficiency. Meanwhile in the United Kingdom, Holdson raised €1.7 million to expand its electroform surface-finishing technology used in sectors such as aerospace, automotive and fusion energy.

Taken together, these rounds amount to over €32 million in funding across advanced manufacturing software, automation and industrial tooling platforms during 2025–2026.

Against this backdrop, London-based Isembard’s €43 million Series A represents one of the larger rounds in this emerging segment, reflecting investor interest in technologies that modernise factory operations, strengthen domestic manufacturing capacity and support the digitisation and automation of industrial production.

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.”

Founded in 2024, Isembard is a British manufacturing company that produces high-precision components and assemblies for industries such as aerospace, defence and energy. Using advanced CNC machining and automation, the company helps hardware startups and industrial firms move quickly from prototype to production while avoiding the delays and complexity of traditional supply chains.

Its factories run on MasonOS, Isembard’s proprietary software platform that manages quoting, scheduling, production and quality control. By combining precision machining with a software-driven factory network, Isembard aims to speed up manufacturing and strengthen Western industrial supply chains.

While Isembard positions itself as a manufacturing and industrial infrastructure company, its focus places it close to sectors often associated with strategic and defence-related technologies. The company produces high-precision components and assemblies used in advanced hardware, including applications in aerospace, energy systems and other industries where reliability.

Its distributed factory model, supported by the MasonOS software platform, is designed to strengthen domestic manufacturing capacity and reduce reliance on global supply chains.

“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,” adds Rebecca.

According to figures provided by the company, component manufacturing is a market worth €1.5 trillion ($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 given re-shoring and spending increases on critical industries.

Without decisive action, the company believes that the widening gap between supply of factories and demand from customers risks hollowing out the industrial base of Europe and North America.

Isembard’s MasonOS integrates quoting, scheduling, supply chain, manufacturing, quality control and delivery into a single intelligent agentic operating layer, automating and optimising factory performance.

The company identifies exceptional 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.
