Almost every precision part in the physical world is produced by a CNC machine. Jet engine blades, hip implants, satellite housings, the case of the watch on your wrist: all of them are cut from solid material by machines executing code with sub-millimetre precision.
The machines are marvels. The bottleneck is the humans who program them. Writing the machining program for a complex part takes days to weeks of skilled work, and the skill itself takes years to build: physics, materials science, and hard-won intuition about how titanium behaves under a specific cutting tool at high heat. One wrong parameter can destroy a machine spindle or scrap an expensive block of metal.
And the people who can do it are disappearing. The average CNC programmer in the West is approaching their 50s, the talent pipeline behind them is thin, and 45% of US manufacturing executives report turning away business because they cannot staff. All of this while demand for domestic manufacturing surges: companies have announced more than $1.7 trillion in new US manufacturing investment since the start of 2025 alone. Factories stand idle not for lack of machines or orders, but for lack of programmers.
For the first time, AI can credibly address this. Models that natively reason about 3D geometry and physics simply did not exist two years ago. This is the moment Limitless Labs was built for, and we're proud to be co-leading their US$20M Series A alongside DTC.
Introducing Limitless Labs
Limitless Labs is building the AI brain for mechanical manufacturing: a physics-based foundation model designed to automate CNC programming, the deepest bottleneck on the modern factory floor.
Their first product is an AI agent for CAM engineers, the people who turn designs into machine instructions. It takes a 3D CAD model as input and generates the machining program, including which tools to use, optimal cutting paths, and appropriate speeds and feeds. It works as a co-pilot inside the platforms engineers already use, with integrations expanding across the CAM ecosystem.
Think of AI code generation, like Cursor or Claude Code, but for the code that runs machines. With one crucial difference: the models underneath are not LLMs. They are physical AI, trained on proprietary manufacturing data that does not exist anywhere on the internet, built to understand part geometry and mentally simulate the physics of cutting metal before a single chip flies.
The payoff goes beyond programming speed. Even a few percentage points of improvement in machine utilisation is worth millions a year to a mid-size manufacturer. And over time, the model becomes something more: the factory's institutional memory. Senior machinists train it, and it scales decades of accumulated know-how to every engineer who comes after them. Limitless is already working with leading manufacturers across aerospace, automotive and other precision industries.
The Team
Limitless Labs was founded in 2024 by David Priev (CEO), Assaf Peleg (CTO) and Dr Shahaf Finder (CSO).
David and Assaf are veterans of Unit 81, the elite Israeli technology unit renowned for building systems that fuse software and mechanical engineering under extreme constraints. The founding insight came from lived experience: they had spent years producing critical components under intense time pressure and ran headfirst into the CNC programming bottleneck. Shahaf, a close friend of David's since high school, completed a PhD specialiszing in 3D perception and transformer architectures, the exact research frontier this problem demands.
It is a team wired for this specific problem: manufacturing domain depth, systems engineering forged in high-stakes environments, and frontier AI research. That wiring is also the sales motion. Manufacturing buys on trust, from people who have stood on a factory floor and know what a scrapped part costs. The founders sell the way they build, in the buyer's own language, and it shows in how early some of the world's most demanding manufacturers trusted Limitless with their parts.
What's next for Limitless Labs?
The Series A will deepen the core model, ship more integrations, and build out the company's presence in the US. The long-term vision is bigger than a co-pilot. It runs from assisted programming today to fully autonomous machining, and eventually to a closed loop from design to production. This is why we believe Limitless Labs has the potential to become the foundational intelligence layer for manufacturing.
We could not be more excited to partner with David, Assaf, Shahaf and the team!
