Phosio Appoints Former Inpria CEO Andrew Grenville to Board of Directors

Phosio is excited to announce that Andrew Grenville, former CEO of Inpria, has joined its Board of Directors. Grenville is a recognized leader in advanced materials and semiconductor innovation, with deep experience guiding materials platforms from early-stage development through manufacturing scale-up and strategic acquisition, including the successful sale of Inpria to JSR Corporation.

“We are thrilled to welcome Andrew to Phosio’s Board,” said Omid Sadeghi, CEO and founder of Phosio. “He has repeatedly demonstrated how to build exceptional teams and translate breakthrough materials into real-world impact. Andrew’s experience co-founding and scaling Inpria alongside Phosio co-founder Doug Keszler is directly relevant as we work to build another category-defining company.”
As CEO of Inpria, Grenville led the commercialization of metal-oxide photoresist materials critical to next-generation semiconductor manufacturing. His leadership helped transform cutting-edge R&D into large-scale industrial adoption and a strategic exit.

“Phosio has the technical foundation and vision to unlock mass-market AR/AI glasses,” said Grenville. “I’m excited to join the Board and help the team scale a platform that can fundamentally change how people interact with digital information.”

Joe O’Keeffe, Executive Chairman of Phosio, added, “Andrew’s ability to bring breakthrough technologies to market and navigate strategic partnerships will be instrumental as Phosio accelerates customer engagement and commercialization.”
Enabling the Next Generation of AR/AI Glasses

AR/AI glasses represent the next major shift in consumer electronics, but widespread adoption has been limited by display technology that is bulky, power-hungry, or expensive. Phosio’s thin-film materials platform addresses this gap by enabling compact, affordable, high-performance displays integrated directly into lightweight eyewear, making visual AI practical for everyday use.
