This two-year-old startup already programs Blue Origin’s rockets. It just raised $20M.

A two-year-old Israeli startup, Limitless Labs, has secured $20 million in Series A funding to advance its AI-driven software for CNC machining, the precision process behind rocket engines and medical implants. The round was co-led by Dell Technologies Capital and Square Peg, with additional backing from Grove Ventures, Meron Capital, and Kinetica, bringing total funding to $27.3 million. The company’s AI agent, trained on metal-cutting physics and CAD geometry, generates ready-to-run machine programs from 3D design files, cutting programming time by up to 50%. The funding addresses a critical manufacturing challenge: nearly a quarter of U.S. factory workers are 55 or older, and 409,000 jobs remain unfilled, with projections warning of a 1.9 million worker shortage by 2033. Limitless Labs’ technology captures the ‘tribal knowledge’ of experienced machinists—expertise often lost when they retire—by integrating with existing software like Siemens NX, Mastercam, and PTC Creo. What sets Limitless apart is its early adoption by high-stakes clients, including Blue Origin, Cadillac’s Formula One team, and defense contractors like Sandvik and ISCAR. The company is ITAR-compliant and uses AWS GovCloud for defense applications, signaling its reliability in industries where programming errors can be catastrophic. The founders, veterans of Israel’s elite 81 tech unit, closed the funding round in three weeks despite geopolitical tensions, including the Iran war. The startup operates in a competitive field, where other companies like THEKER, NEURA Robotics, and industry giants such as Fanuc and Google are investing heavily in ‘Physical AI’ for factory automation. While $20 million is modest compared to rivals raising hundreds of millions, Limitless aims to achieve ‘closed-loop’ automation—though for now, human engineers still sign off on programs. The ultimate test remains replicating a master machinist’s instincts with enough precision to trust in critical applications like rocket manufacturing.
