Limitless Labs raises $20M to deploy AI agents that capture retiring machinists' expertise

Limitless Labs Secures Series A Funding to Transform Manufacturing

Limitless Labs has closed a $20 million funding round led by Dell Technologies Capital and Square Peg, with participation from Grove Ventures, Meron Capital and Kinetica1

1

. The Series A funding brings the Tel Aviv-based company's total capital raised to $27.3 million, following a $4.1 million seed round in March 20252

2

. The investment positions Limitless Labs, formerly known as LimitlessCNC, to expand its AI-driven CNC machining technology across US manufacturing operations facing an unprecedented skills crisis.

Addressing Critical Manufacturing Skills Gap with AI Agents for Precision Manufacturing

The urgency behind AI in manufacturing stems from stark demographic realities. Nearly a quarter of US manufacturing workers are 55 or older, while approximately 409,000 factory jobs sit unfilled1

. Projections indicate this gap could reach 1.9 million positions by 2033. Much of the expertise critical to precision metal-cutting operations exists as what the industry calls 'tribal knowledge'—skills accumulated over decades that reside solely in the minds of master machinists. "The manufacturing world doesn't just need more automation, it needs a better way to capture and scale the expertise that still lives inside the heads of a relatively small number of experienced machinists," explained co-founder and CEO David Priev2

Physical AI Trained on Real-World Manufacturing Constraints

Unlike large language models trained on text, Limitless Labs deploys Physical AI trained on the physics of metal cutting, machine operational limits and CAD geometry1

. The platform integrates directly with software engineers already use, including Siemens NX, Mastercam and PTC Creo. When provided with a 3D design file, the CAM agent identifies features, selects cutting tools, sequences operations and generates ready-to-run machine programs, reducing programming time by up to 50%2

2

. This approach to automate programming of precision metal-cutting machines addresses bottlenecks that slow production across aerospace, automotive, medical devices and consumer goods sectors.

Blue Origin and Formula 1 Validate Production-Ready Technology

What distinguishes Limitless Labs at the Series A funding stage is its roster of demanding customers already using the technology in production environments. The company works with Blue Origin on rocket components, Cadillac's Formula One team, industrial giant Sandvik and toolmaker ISCAR1

. These aerospace and Formula 1 applications operate where programming errors can prove catastrophic and tolerances are measured in microns. The platform maintains ITAR compliance and runs on AWS GovCloud for defense-related work. Landing such high-stakes customers while competitors remain stuck in pilot programs signals the technology's reliability. The founders, including veterans of the IDF's elite 81 tech unit, closed the funding round in just three weeks1

Scaling Across Expanding Manufacturing Demand

The design-to-machining pipeline faces mounting pressure as multiple industries compete for limited machining capacity. According to market research, the precision manufacturing sector reached $3.38 billion in 2025 and is projected to exceed $5.09 billion by 20302

2

. Simultaneous expansion across aerospace, defense, electric vehicles, medical devices, electronics and consumer goods creates unprecedented demand. "We believe the next major AI platform will be built for the physical world, and that starts with giving manufacturers a way to scale their best knowledge across every new part and every new engineer," Priev stated2

2

. With manufacturing jobs reshoring to the United States at increased rates, the domestic skills shortage becomes even more acute.

What Comes Next for Factory Floor Automation

Limitless Labs will deploy the new capital to expand its US commercial organization, advance the Physical AI foundation model and grow the CAM agent's capabilities2

2

. The company aims to push toward 'closed-loop' automation, though currently a human engineer still approves every generated program1

1

. Capturing a master machinist's instincts reliably enough to trust on rocket components represents the ultimate technical challenge. The company operates in an increasingly crowded field where Barcelona's THEKER raised €73 million for factory robots, NEURA Robotics secured up to $1.4 billion, and established players from Fanuc to Google race to integrate AI into manufacturing1

1

. "Eighteen months ago, we backed Limitless Labs' vision that agentic AI could transform the factory floor," said Lior Handelsman, general partner at Grove Ventures. "What the team has achieved since then has exceeded expectations"2
