Uptown-based physical AI company Shelfmark raised a $3.5 million seed round, with plans to scale local hiring.

Over the next 18 months, the company will use the funding to grow the team by roughly half a dozen people as part of its strategy to increase sales and product delivery, Pat O’Donnell, cofounder and CEO of Shelfmark, told Technical.ly.

Finding the perfect fit for those roles is another story, as the company hunts for technologists in the area looking to grow with its physical AI and manufacturing-focused team.

“We want to continue growing in Pittsburgh. We don’t want to open another office elsewhere,” O’Donnell said. “To do that, we need to find talented people to fill these roles.”

Armory Square Ventures, based in New York, alongside Grand Ventures, Hyde Park Angels, Argon Ventures and Cultivation Capital led the recent round.

Shelfmark builds autonomous inspection tech for manufacturing lines, specifically products made on reels and rolls such as flooring, paper, webbing and more.

The 2025 RealLIST Startups honorable mention recipient’s industrial cameras and vision models aim to detect defects before products leave the floor.

Going global, building local

Shelfmark also has its eyes set beyond Pittsburgh. It will be installing its first units in Europe — it already has customers in Australia and New Zealand — next month, still aiming to bring those wins back to locals.

O’Donnell himself is a University of Pittsburgh and Carnegie Mellon University grad, and the majority of the 10-person team graduated from one of those schools, too.

“We have brought back a number of Pittsburgh natives that went elsewhere,” O’Donnell said. “We’ve taken folks from Washington, DC, from Chicago, from Boston, from really all over the map to come back to Pittsburgh and solve hard problems here.”

Beyond the academic background, Shelfmark has leaned into other community staples as it grows. As an Innovation Works portfolio company and partner with RIDC, O’Donnell said those existing structures will help the company hire qualified candidates in the city.

“This fundraise is just the start of being able to take this market and to establish Shelfmark and establish Pittsburgh as a leader in physical AI,” O’Donnell said.

A hands-on origin story

When Shelfmark was founded in June 2022, the idea came from the factory floors, 4 a.m. shadow shifts and identifying manufacturing problems.

“This specific problem of inline inspection and intelligence came directly from working with manufacturing partners that are still customers to this day, and solving meaningful problems for them,” O’Donnell said.

The company began in retail with the overarching goal of ensuring its customer’s products are the ones getting onto shelves and meeting a certain benchmark.

So came the name Shelfmark — memorable, easy to say and indicative of a high-standards operation.

“It’s about ensuring that the products that our customers make, the products that are getting placed on shelves,” O’Donnell said, “[and] meet the criteria and the excellence that they seek to put out into the market.
