London-based CloudNC has raised $20 million to accelerate AI software that cuts CNC programming from hours to seconds, backed by Lockheed Martin's venture arm and now serving more than 1,000 machine shops worldwide.
Key Takeaways
- CloudNC's Series B extension is led by Nimble Ventures, with LM Ventures, Calculus Venture Capital, and Entrepreneur First participating.
- The round brings CloudNC's lifetime capital raised to $128 million, following a $45M Series B closed in June 2022.
- Lockheed Martin is both an investor and a named customer, and CloudNC is pursuing FedRAMP certification for U.S. defense contracts.
Lead
CloudNC, the London-based manufacturing AI startup, closed a $20 million Series B extension on September 8, 2026, led by Nimble Ventures. The capital brings the company's total funding to $128 million and arrives four years after its last major raise. Participation came from Calculus Venture Capital, Entrepreneur First, and LM Ventures - Lockheed Martin's corporate venture fund. Lockheed Martin also figures on the customer list, a pairing that signals something more than passive interest from the defense giant.
What CloudNC Actually Does
The company's flagship product, CAM Assist, targets the most labor-intensive step in precision manufacturing: translating a finished CAD file into a detailed machining strategy. A skilled CNC programmer can spend hours mapping out toolpaths and milling sequences for a single part. CAM Assist plugs into industry-standard software packages - Autodesk Fusion, Mastercam, and Siemens NX - and generates those same plans in seconds.
The pitch is not novelty. CNC machining is a 70-year-old industry where the bottleneck has always been human expertise, not raw machine capacity. What CloudNC is selling is a replication of that expertise at scale, at a time when skilled machinists are increasingly scarce in both the U.S. and U.K. markets. The software now runs inside more than 1,000 machine shops globally, with hundreds of those in the United States.
Why Does Lockheed Martin Care?
The dual role - investor and customer - is the clearest signal in this round. Defense supply chains run on precision machined components, and the contractors who make them face the same skilled-labor shortage as commercial shops. If CAM Assist can reliably compress programming cycles, it has direct value for defense prime contractors and their tier-one suppliers.
CloudNC is also working with Knox Systems toward FedRAMP certification for CAM Assist. FedRAMP is the U.S. federal compliance framework required to sell software to government agencies and defense contractors handling classified or sensitive workloads. Certification is a lengthy process, and the fact that CloudNC has started it suggests the company is treating the defense vertical as a serious revenue line, not a marketing credential.
What Is the $20M For?
The funds will go toward two things: commercial expansion in existing and new markets, and new product development. The most concrete addition in the pipeline is Quote Agent, an AI tool designed to automate quoting and cost estimation for machine shops. Quoting is a second major bottleneck in the manufacturing workflow - estimating what a job should cost involves its own expertise - and the product would extend CloudNC's footprint beyond programming alone.
The company has not disclosed revenue, margins, or a current valuation. The round is structured as a B extension rather than a Series C, which means the price was presumably set off the 2022 terms. Whether those terms look generous or conservative after four years of market repricing in AI software is a question the company is not answering publicly.
Strategic Context
Autodesk was an investor in the 2022 Series B, and CAM Assist integrates directly with Fusion - Autodesk's dominant CAD/CAM platform. That relationship remains structurally significant. Any machine shop already running Fusion is a near-zero-friction prospect for CloudNC, which matters a great deal when a startup is trying to grow from 1,000 shops to 10,000.
The broader AI-in-manufacturing category has attracted substantial capital in the past two years, with rivals including Verisurf, Sandvik's digital tools division, and a range of point-solution vendors. CloudNC's differentiation is depth of integration with existing CAM packages rather than a standalone product requiring workflow replacement. That reduces adoption friction but also makes the product harder to defend if the CAM vendors themselves decide to build competing features natively.
Outlook
CloudNC enters the second half of 2026 with $128 million in cumulative backing, a confirmed defense-sector anchor in Lockheed Martin, and a product already embedded in four figures of shops globally. The FedRAMP track is the highest-stakes near-term execution test - it would open U.S. government contract opportunities that most software companies never get near. Quote Agent, expected before year-end, would either deepen existing customer relationships or prove difficult to differentiate in a market where quoting tools already exist. The round buys time. How the company uses it is the open question.
