Limitless Labs raises $20M to automate CNC manufacturing with AI

Limitless Labs has closed a $20 million Series A round to expand its AI-powered automation platform for CNC manufacturing, bringing the Israeli startup's total funding to $27.3 million since its 2024 founding.

Dell Technologies Capital and Square Peg led the round, with participation from Grove Ventures, Meron Capital, and Kinetica, according to details first reported by Calcalist.

The company, formerly known as LimitlessCNC, builds AI agents that integrate directly into the computer-aided manufacturing (CAM) software already used by precision manufacturers. The technology addresses a persistent bottleneck: translating digital part designs into the specific toolpaths and cutting parameters that CNC machines need to execute.

How the platform works

Limitless Labs trained its AI model on the physics of metal cutting, the geometric constraints of design files, and the real-world limitations of industrial machines. When a manufacturing engineer loads a part design into CAM software, the AI agent analyzes the geometry against the target machine's capabilities and plans the full production sequence—selecting cutting tools, generating toolpaths, and optimizing cutting conditions.

The company reports the system reduces programming time by up to 50 percent, allowing senior machinists to focus on complex problems rather than routine setup tasks.

Early traction in aerospace and automotive

Since moving beyond pilot projects, Limitless Labs has secured production deployments with Blue Origin, Cadillac Formula 1, and cutting tool manufacturer ISCAR. The startup has also partnered with Sandvik's Cimatron, a CAD/CAM provider with approximately 30,000 active users globally.

The company was founded by David Priev and Assaf Peleg, both alumni of Israeli Defense Forces Unit 81 who previously developed engineering solutions for complex 3D software, alongside Shahaf Finder, a machine learning doctoral researcher at Ben-Gurion University.

Why it matters

Manufacturing expertise remains concentrated in a shrinking pool of experienced machinists who carry decades of tribal knowledge. As that workforce ages out, companies face a growing skills gap that threatens production capacity. AI systems that can codify and scale that expertise—without requiring manufacturers to abandon existing workflows—offer a practical path to maintaining output as human expertise becomes scarcer. The approach also positions AI as an augmentation tool rather than a replacement, a framing that may ease adoption in an industry historically resistant to radical process changes.

Expansion plans

The new capital will fund U.S. market expansion, continued development of the AI model toward full CNC process automation, and growth of the Tel Aviv development center. Limitless Labs expects to double its workforce over the next year.

"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," said Priev. "We built Limitless Labs to work inside the CAD/CAM systems manufacturers already use, helping teams standardize best practices, reduce programming bottlenecks, and free senior programmers to focus on the hardest work, without giving up control."
