Limitless Labs Raises $20M to Expand Physical AI

According to a PR Newswire release, Limitless Labs (formerly LimitlessCNC) announced a $20 million Series A financing round co-led by Dell Technologies Capital and Square Peg, with participation from Grove Ventures, Meron Capital, and Kinetica. The PR Newswire release reports the company has progressed from pilots to full production deployments with named production customers including Blue Origin, Cadillac's Formula One team, Sandvik, and Iscar across aerospace, defense, motorsports, and industrial machinery, and claims reductions in CNC programming time of up to 50%. The same release describes the platform as ITAR-compliant and deployable on AWS GovCloud. SiliconANGLE reports Limitless Labs previously raised a $4.1 million seed round in March 2025 led by Grove Ventures and quotes co-founder and CEO David Priev: "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."

SiliconANGLE frames Limitless Labs' product as an "agentic physical AI" platform that operates inside established CAD/CAM workflows; the outlet reports the company says its agents are trained on the physics of metal cutting, CAD geometry, and machine operational constraints. Industry-pattern observations: domain-specific agentic systems typically combine structured engineering data, physics-informed models, and constrained action spaces to avoid unsafe toolpaths or damaging machine cycles. For practitioners, that pattern implies investments in accurate simulation, tooling-specific constraint enforcement, and traceable verification will be essential when integrating agents into production CNC toolchains.

Per the PR Newswire release, the company cites workforce and skills statistics: nearly a quarter of the US manufacturing workforce is 55 or older, 97% of manufacturers list knowledge retention as a top concern, with 409,000 positions currently unfilled and a projected shortfall reaching 1.9 million by 2033. Industry observers: markets facing skilled-labor shortages often accelerate adoption of automation and knowledge-capture technologies; vendors that can demonstrate repeatable quality improvements and compliance with regulated environments tend to gain earlier traction in aerospace and defense supply chains.

Industry observers will track three practical indicators: adoption beyond early pilots (notably additional OEMs or Tier-1 suppliers), independent validation of the claimed 50% programming-time reduction (benchmarks across part families and machine types), and certifications or controls tied to regulated deployments (evidence of ITAR workflows or validated GovCloud instances). Also watch integrations with major CAD/CAM vendors and how the platform manages provenance and traceability of generated toolpaths-items that matter to quality engineers and auditors.

Companies building or evaluating physical-AI agents should plan to assess data lineage, simulation fidelity, and per-machine calibration workflows. Observed patterns in similar transitions show that tooling-specific constraints, deterministic verification steps, and human-in-the-loop signoff gates reduce operational risk when moving from pilot to shop-floor production.
