Path Robotics raises $300m Series E to take its welding AI further

10 November 2026: Path Robotics says it has raised $300 million in a Series E led by Georgian at a valuation of $2.45 billion, money it will use to grow its robotic welding business and build models for the other jobs on a factory floor. Defence manufacturing is a clear part of the story: Lockheed Martin Ventures and shipbuilder HII both speak in the announcement.

Not yet independently verified. The investor list beyond the lead and the company's headquarters are not stated in the release; Lockheed Martin Ventures and HII are quoted, but their exact roles in the round are not given. We will update this when it can be confirmed, and remove this note.

From the hardest weld to the whole factory

The company sells intelligent welding cells, marketed under the name Obsidian, that use its own AI models to weld parts that traditional robots handle poorly, such as short runs and variable parts. Its chief executive frames welding as the beachhead rather than the destination.

"We started with welding because it is one of the hardest jobs on the factory floor to automate," said Andy Lonsberry, chief executive and co-founder. The new money, he said, lets the company scale welding "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 Robotics says the capital goes to three things: expanding the welding business with existing customers, data and compute for model development, and new applications and industries.

Investors with a shipyard in mind

Emily Walsh, partner at Georgian, said the firm believes Path Robotics "is well positioned to become one of the defining companies in industrial physical AI", pointing to its models and a growing base of real production data, where each deployment improves the system.

The other two voices are defence names. Chris Moran, vice president and general manager of Lockheed Martin Ventures, tied the investment to capacity: "As demand for critical defense systems continues to grow, scaling production requires innovative approaches." HII's Eric Chewning, executive vice president of maritime systems and corporate strategy, described HII as America's largest shipbuilder and said partnering with physical AI companies such as Path Robotics supports "increased throughput and acceleration of production" in shipbuilding fabrication. The company's own news list records HII performance-based production agreements with Path Robotics and GrayMatter Robotics in August.

What the valuation and claims rest on

The $2.45 billion figure is the company's. Some press headlines round it to $2.5 billion. The release names no other investors in the round and gives no revenue figure in the text, so the scale of the business behind the valuation is the company's to disclose.

The robotics companies we list

Welding cells sit between two of our categories: robot manufacturers, with 63 companies, and industrial automation companies, with 49. A further 25 firms sit under robotics system integrators, the companies that usually put cells like these onto a customer's line. Buyers comparing a welding cell with a conventional robot plus integrator will find both routes there.
