Alex Lonsberry

Co-Founder and Chief Technical Officer Path Robotics

Last Reviewed: September 28, 2026

Executive Summary

Alex Lonsberry is co-founder and Chief Technical Officer of Path Robotics, the Columbus, Ohio company that builds AI-driven welding systems for manufacturers and, increasingly, shipbuilders. He started the company with his brother Andy, now its CEO, after both brothers completed doctorates at Case Western Reserve University. Path’s own description of his job is plain: he has worked alongside his brother since the first day to architect and build the company’s AI and hardware platforms. Those are the two halves of what Path sells: welding robots and the AI that directs them.

Career Highlights

• Co-founder of Path Robotics; listed by the company as Chief Technical Officer and responsible, in its words, for architecting and building Path’s AI and hardware platforms.
• Named as a director of Path Robotics, Inc. in the company’s 2021 Form D filing with the SEC.
• Holds a doctorate from Case Western Reserve University, where his brother and co-founder also completed a doctorate.
• Path Robotics launched Rove, a mobile welding system that pairs its AI with a quadruped robot, in April 2026, with Saronic Technologies among the first to deploy it.
• In August 2026, HII announced multi-year production agreements worth up to $900 million with Path Robotics and GrayMatter Robotics to expand U.S. shipbuilding capacity.

Professional Journey

The Lonsberry brothers grew up in suburban Cleveland, where their father was a mechanical engineer who for several years ran a factory building off-road vehicles. The company tells the story as two boys welding with their father in the garage; the Ohio State Alumni Magazine adds that the brothers spent weekends in his shop as children. Both went on to study mechanical engineering and then completed doctoral degrees at Case Western Reserve University, with computer science worked into their engineering training.

Path Robotics grew out of that combination. The Ohio State magazine describes it starting in a basement shop in Cleveland before moving to Columbus in 2019. The company’s SEC filings describe a Delaware corporation incorporated in 2018 with Alexander Lonsberry as a director alongside his brother, who serves as CEO. Path now describes itself as a leader in physical AI for manufacturing: robotic welding systems whose AI and hardware are designed together, which is the platform Alex Lonsberry is credited with architecting on both sides.

The company’s recent announcements show where that technology has gone. In February 2026 the shipbuilder HII signed a memorandum of understanding with Path to bring what both call physical AI into shipbuilding. In April 2026 Path launched Rove, which mounts its welding system on a quadruped robot so it can work in the confined, hard-to-reach spaces of a ship’s hull, and which Saronic Technologies has been testing in vessel production. In August 2026 HII followed with multi-year performance-based production agreements worth up to $900 million, shared between Path Robotics and GrayMatter Robotics. Path’s backers, as listed by the company, include Drive Capital, Matter Venture Partners, Yamaha Motor Ventures, Tiger Global and Addition.

Education

Case Western Reserve University

PhD. The company describes both founders’ PhDs as being in AI-related fields; the precise field and year of his degree were not established from a first-party source. His undergraduate study was in mechanical engineering, at an institution not named in the sources found.
