CloudNC raises $20M to point AI at the factory floor

CloudNC, a London company, has raised $20M — about £15M — to expand a product aimed at a corner of the economy that most AI money ignores: the factory floor. Its flagship, CAM Assist, uses AI to automate CAM programming, the skilled and painstaking work of deciding the exact toolpaths a CNC machine will follow to cut a piece of metal into a finished part. The round was led by the US firm Nimble Ventures, with the UK talent-first accelerator Entrepreneur First, Calculus Venture Capital, and LM Ventures — Lockheed Martin’s venture arm — also taking part.

CAM programming is a genuine bottleneck. It is expert work, done by hand by a shrinking pool of skilled programmers, and it sits between a design and the moment a machine can start cutting. CloudNC’s pitch is that CAM Assist, which plugs into the CAM software shops already use, can do up to 80% of that programming automatically and in minutes rather than hours. The company says its tools are now used by more than 1,000 machine shops worldwide, including hundreds in the US, with named customers including Lockheed Martin and Major Tool and Machine. A new product, Quote Agent — an AI agent aimed at the equally laborious job of quoting and estimating — is due later this year.

The backers are part of the story. Entrepreneur First has seeded a long line of UK AI companies by betting on technical founders before they have a company at all. And Lockheed Martin appearing as both a customer and, through LM Ventures, an investor says something about where advanced manufacturing is heading: aerospace and defence primes have vast, precise machining needs and an acute shortage of the people to program them, which is exactly the gap CloudNC is selling into.

It is worth reading alongside the other end of the “AI meets the physical world” spectrum we have been tracking. Where Embedd automates the software that lets machines run at all, CloudNC automates the machine-learning-driven programming that tells a machine what to make. Both are bets that a great deal of AI’s near-term value lies not in chatbots but in the unglamorous, labour-constrained work of making real things — and that the UK, with a real advanced-manufacturing and aerospace base, is a sensible place to build it.

The open question is the one that shadows any AI tool aimed at skilled work: whether it augments the people doing the job or replaces them. CloudNC frames CAM Assist as a way to get more out of scarce, experienced machinists rather than do without them, and given how short the trade is of skilled programmers, that is the more plausible near-term story. But it is the thing to watch as tools like this move from a helpful assistant to doing most of the work — on the factory floor as much as anywhere else.
