Path Robotics raises $300M Series E at $2.45B valuation for manufacturing AI expansion

Path Robotics has raised $300 million in Series E financing at a $2.45 billion post-money valuation, providing capital to expand its physical AI technology beyond welding into additional manufacturing tasks and robotic platforms. Georgian led the round, with participation from existing investors Addition, Drive Capital, IronArc Ventures, Tiger Global, Yamaha Motor Ventures and its affiliates. D. E. Shaw Ventures and NAVER Ventures also participated. Georgian Partner Emily Walsh will join Path Robotics’ board of directors.

The Columbus, Ohio-based company said annual recurring revenue increased 17-fold over the past 18 months as deployments expanded among industrial customers in North America. Since its founding in 2018, Path Robotics has raised more than $610 million.

The new financing will support deployment across industries important to U.S. manufacturing capacity, expansion into tasks beyond welding, and increased spending on AI model training and computing resources.

Path’s Obsidian welding model uses production data to enable robots to identify joints, plan and execute welds, and adapt to changing conditions. The company is extending those capabilities across different robotic formats, including Rove, a mobile welding system built on a quadruped platform.

Customers include HII, Lockheed Martin and Saronic, alongside manufacturers such as EK Machine, Millerbernd Manufacturing Company, TransAmerican Power Products and TYCROP.

Earlier in 2026, Path announced a $600 million performance-based production agreement with HII supporting physical AI deployment across U.S. Navy shipbuilding programs.

The company has increased its workforce by 97% year over year and plans to reach 400 employees by year-end.

Path’s expansion targets manufacturing tasks where variable conditions make conventional programming difficult. Its strategy is to build on welding deployments and production data to address additional factory processes.

KEY QUOTES

“We started with welding because it is one of the hardest jobs on the factory floor to automate, and we’ve proven that our technology can succeed in real production environments. We’re seeing accelerating demand from manufacturers that need to expand production capacity but can’t get there with traditional automation. 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.”

Andy Lonsberry, CEO And Co-Founder Of Path Robotics

“We believe Path Robotics is well positioned to become one of the defining companies in industrial physical AI. Path’s proprietary models and growing base of real-world production data can create a powerful advantage, with every deployment helping improve the intelligence behind its systems. The team has built a strong foundation in welding, and we see enormous potential for Path Robotics to extend that intelligence to new manufacturing applications and industries.”

Emily Walsh, Partner At Georgian

“As demand for critical defense systems continues to grow, scaling production requires innovative approaches. Our work with Path Robotics advances manufacturing solutions in ways that can help expand capacity. This investment is an important milestone for Path and the broader industry, accelerating the development of technologies that will help strengthen America’s defense industrial base.”
