Path Robotics builds welding systems for manufacturers such as HII, Lockheed Martin, and Saronic, plus mid-sized companies that fabricate heavy equipment and infrastructure components. Cameras and the Obsidian AI model allow the robots to locate seams on large, inconsistent parts, plan each weld, and adjust while welding so the work does not depend on custom motion programs or perfect part fit-up. The firm raised $300 million in a Series E at a $2.45 billion valuation led by Georgian and reports that annual recurring revenue increased 17-fold over the previous 18 months. Andy Lonsberry, CEO, and his brother Alex Lonsberry, CTO, founded the company in 2018 after completing robotics PhDs at Case Western Reserve University. They learned to weld as children in their father’s garage shop in Ohio. With total funding now above $610 million, the round will expand welding deployments and support development of tasks before and after welding, along with new robot designs such as Rove, a legged platform that carries the welding software to large structures at shipyards.
