What Isembard does
Isembard is a London-headquartered distributed precision manufacturing company founded in 2024 by Alexander Fitzgerald, operating software-powered factories that produce high-precision components for aerospace, defence, energy and robotics customers across the UK, US and Germany. Its core product is MasonOS, a proprietary AI-driven operating system that integrates quoting, scheduling, supply chain, manufacturing execution, quality control and delivery into a single agentic orchestration layer — described as a replacement for fragmented legacy ERP systems. MasonOS applies machine learning to instant quoting (analysing 3D model geometry, material and process), AS9100D-compliant defect prediction via computer-vision inspection, autonomous scheduling, supply chain automation and closed-loop production optimisation, with company-claimed outcomes of 10x faster quoting cycles, 40-60% throughput improvement and ~30% operating cost reduction. Manufacturing capabilities currently span 5-axis CNC milling and turning, assembly and injection moulding, with planned expansion into fabrication, forging, casting, additive manufacturing and wire harness.
Isembard monetises through multiple revenue streams: contract manufacturing services for precision components (the dominant current revenue stream), franchise fees and royalties from operators running Isembard-branded factories powered by MasonOS, planned white-label MasonOS software licensing, and professional/engineering services including Design-for-Manufacturability feedback. The go-to-market is enterprise sales-led via direct RFQ ([email protected]) supplemented by PR-driven awareness, an RFQ self-serve storefront, industry events and a franchise recruitment channel. Pricing is quote-based per component or project with no public price list. The company holds a stack of aerospace and defence certifications (AS9100, ISO 9001, ITAR, Cyber Essentials, JOSCAR) that small machine shops typically cannot afford independently, and is positioned as a sovereign UK/US/German supplier to defence primes and NewSpace customers including Anduril UK, Rowden Technologies, Dexory, Tekever, ARX Robotics, Third Planet Orbital and Imperial College Space Society. Total funding raised is approximately $59M ($9M seed in April 2025 led by Notion Capital; $50M Series A in March 2026 led by Union Square Ventures), with a stated target of scaling from 5 to 25 factories by end of 2026.

Revenue model
- Precision Component Manufacturing Services: Core revenue from contract manufacturing of high-precision CNC components (5-axis milling & turning, assembly, injection moulding) for aerospace, defence, energy and robotics customers. Customers request quotes via RFQ; work is performed in Isembard's owned and franchise factories. Drives the majority of revenue today.
- Software Licensing (MasonOS White-Label): Future / emerging stream: license MasonOS to third parties as a white-label service to power their own factories, alongside owned and franchise use. Not yet a material revenue contributor but explicitly part of the long-term plan.
- Franchise Fees & Royalties: Revenue from granting Isembard franchise rights to operators who launch or convert factories under the Isembard brand; franchisees gain access to MasonOS, customer pipeline, financing pathways and accreditation support in exchange for franchise fees/royalties.
- Professional / Engineering Services: Design optimisation, Design-for-Manufacturability (DfM) feedback and rapid prototyping services bundled with production work, supporting customers from prototype through scale.

Isembard product offering
Product offeringCore offering
Isembard operates a distributed network of software-powered precision factories that contract-manufacture high-precision 5-axis CNC components for aerospace, defence, energy and robotics customers. Every Isembard site runs MasonOS, a proprietary AI-driven operating system that integrates quoting, scheduling, supply chain, manufacturing, quality control and delivery into a single agentic layer. Isembard also licenses the MasonOS software model to third-party operators through a manufacturing franchise program that builds out additional Isembard-branded capacity.
Product overview
Isembard offers a single unified platform-plus-network architecture built around MasonOS, its proprietary AI-driven operating system. MasonOS is the core software platform that automates and orchestrates every aspect of Isembard's distributed network of precision factories and franchise sites - integrating quoting, scheduling, supply chain, manufacturing, quality control and delivery into one agentic layer. On top of this platform, Isembard delivers three integrated offerings: (1) Isembard Manufacturing Services, the core production service spanning 5-Axis Milling & Turning, Assembly, Injection Moulding and (coming soon) Fabrication, Forging, Casting, Additive and Wire Harness; (2) the Isembard Manufacturing Franchise program, which lets operators own and run Isembard-branded factories powered by MasonOS; and (3) the Factories-as-a-Service operating model that standardises quality, data and supply chain connectivity across the network. Together, these products form a vertically integrated manufacturing franchise super-prime targeting aerospace, defence, energy and robotics customers in the UK, US and Europe.
