Limitless Labs secures $20 million to introduce AI to manufacturing facilities.

      The most exciting trend in AI today is not another chatbot; it is software capable of operating factory machinery. An Israeli startup, just two years old, has raised $20 million based on its programming components for Jeff Bezos's rockets.

      Limitless Labs, previously known as LimitlessCNC, has successfully closed a $20 million Series A funding round, co-led by Dell Technologies Capital and Square Peg, alongside Grove Ventures, Meron Capital, and Kinetica. This brings the company's total funding to $27.3 million.

      Based in Tel Aviv, the company develops an AI agent for CNC machining, which is the precision metal-cutting process used for everything from rocket engines to medical implants. By inputting a 3D design file, the software selects the appropriate cutting tools, organizes the processes, and generates a machine program ready for execution, which can reduce programming time by as much as 50%.

      Addressing an impending demographic challenge, Limitless is tackling a significant issue: nearly a quarter of manufacturing workers in the U.S. are 55 or older. Currently, there are about 409,000 unfilled factory jobs, and this shortfall is projected to reach 1.9 million by 2033. Much of the expertise resides in the minds of seasoned machinists, often referred to as ‘tribal knowledge,’ and it leaves the workforce when they retire. Co-founder and CEO David Priev stated, "The manufacturing industry requires a better method to capture and scale the expertise held by a relatively small group of experienced machinists."

      Unlike models trained on text, Limitless asserts that its ‘Physical AI’ is designed based on the physics of metal cutting, the limitations of machines, and CAD geometry, seamlessly integrating with software already utilized by engineers such as Siemens NX, Mastercam, and PTC Creo.

      What's remarkable is their list of clients. Limitless is presently in production with Blue Origin, Cadillac’s Formula One team, Sandvik, and toolmaker ISCAR, industries where programming mistakes can be disastrous and tolerances are measured in microns. The company complies with ITAR regulations and operates on AWS GovCloud for defense projects.

      Securing contracts with these notable names at the Series A stage, while many competitors remain in pilot phases, is a strong indicator that their approach is effective. The founders, including two who are veterans of the IDF’s elite 81 tech unit, completed the funding round in three weeks. Priev recounted that the U.S. investor roadshow coincided with the early days of the Iran war, with his family taking shelter at home while he presented overseas.

      The term ‘Physical AI’ is rapidly becoming popular. Companies such as Barcelona’s THEKER, which raised €73 million for factory robots, and NEURA Robotics, which attracted up to $1.4 billion, alongside major players like Fanuc and Google, are all racing to incorporate AI into manufacturing. Compared to them, Limitless's $20 million seems modest.

      Nevertheless, a greater challenge lies ahead. Limitless aims to advance towards 'closed-loop' automation, though currently, a human engineer must approve every program. The true test is whether they can reliably encapsulate a master machinist's instincts in a model that can be trusted for rocket production, which is the ultimate goal of their funding.
