Path Robotics Raises $300M in Series E Funding to Expand Manufacturing AI

Insider Brief

• Path Robotics raised $300 million in Series E funding at a $2.45 billion post-money valuation to expand its physical AI technology beyond welding into other manufacturing operations.
• The Georgian-led round follows a 17-fold increase in annual recurring revenue over 18 months, with customers including HII, Lockheed Martin and Saronic.
• The company plans to expand its Obsidian AI welding technology to additional manufacturing tasks and robotic platforms, building on its recently introduced Rove quadruped welding system.

Path Robotics has raised $300 million in Series E funding at a $2.45 billion post-money valuation as the industrial robotics company looks to expand beyond automated welding into other work.

According to Path, the round was led by Georgian, an AI-focused growth equity firm, with participation from existing investors Addition, Drive Capital, IronArc Ventures, Tiger Global and Yamaha Motor Ventures and its affiliates. New investors included D. E. Shaw Ventures and Naver Ventures. Emily Walsh, a partner at Georgian, will join the Columbus, Ohio, company’s board of directors.

Co-founder and CEO Andy Lonsberry said Path Robotics initially focused on welding because of the difficulty of automating the process and has since demonstrated its technology in production environments.

“We’re seeing accelerating demand from manufacturers that need to expand production capacity but can’t get there with traditional automation,” Lonsberry noted. “This capital allows us to scale our welding business alongside our customers while investing further in the data, compute, and model development needed to take on every task before and after welding. Our goal isn’t to automate one step, but to automate the entire factory.”

Path reported that annual recurring revenue has grown 17-fold over the past 18 months as it expanded deployments among industrial manufacturers across North America. The company serves customers in shipbuilding, defense, heavy equipment and energy infrastructure.

Expanding Industrial Deployments

Path’s customers include HII, Lockheed Martin and Saronic, as well as manufacturers such as EK Machine, Millerbernd Manufacturing Company, TransAmerican Power Products and TYCROP. Earlier this year, the company announced a $600 million performance-based production agreement with HII, the largest U.S. shipbuilder, to accelerate deployments of its technology across U.S. Navy shipbuilding programs.

Path reported it has also increased its workforce by 97% year over year and plans to reach 400 employees by the end of 2026.

Building on Autonomous Welding

Path’s Obsidian AI model allows robots to identify welding joints, plan and execute welds, and adjust their movements as conditions change. Conventional industrial robots generally follow predetermined paths, making it difficult to automate manufacturing tasks that vary from one operation to another. Path’s technology uses models trained on real-world welding data to guide robotic movements without relying entirely on fixed instructions.

The company is now extending that approach to other manufacturing operations and types of robots.

Path recently introduced Rove, a mobile welding system that combines Obsidian with a quadruped robotic platform. The company pointed out the system demonstrates how its AI models can be used with different robotic designs and that the new capital will help it develop models for additional uses while expanding the computing and training resources needed for that work.
