Leadership Comments

“Continuous-flow manufacturers make the materials and components that keep the economy moving, but most quality systems are not built for the speed, variation and complexity of their production lines,” said Pat O’Donnell, CEO of Shelfmark. “We built Shelfmark in Pittsburgh, alongside operators and engineers on real factory floors, to give those lines the intelligence they need to become more autonomous.

“Over the past few years, we’ve watched Shelfmark pair deep technical capability with measurable results for manufacturers,” said Anthony Santaro, vice president at Armory Square Ventures. “The team is serving a large, overlooked market with technology designed around how factories actually operate.
