Phosio has appointed Andrew Grenville, former Chief Executive Officer of Inpria, to its Board of Directors as the company advances efforts to commercialize next-generation augmented reality (AR) and artificial intelligence (AI) glasses. The appointment adds deep experience in advanced materials, semiconductor manufacturing, and technology scale-up to Phosio’s leadership team.
Grenville is widely recognized for guiding materials platforms from early-stage research through industrial adoption and strategic acquisition. As CEO of Inpria, he led the commercialization of metal-oxide photoresist materials used in advanced semiconductor manufacturing, helping transform academic research into a widely adopted production technology. Inpria was acquired by JSR Corporation, marking one of the notable materials-focused exits in the semiconductor ecosystem.
Phosio CEO and founder Omid Sadeghi said Grenville’s track record aligns closely with the company’s current stage of growth. He noted that Grenville’s experience co-founding and scaling Inpria alongside Phosio co-founder Doug Keszler brings relevant insight as Phosio works to translate materials innovation into commercial products.
Phosio is developing a thin-film materials platform designed to address key barriers limiting the adoption of AR/AI glasses. While the category is viewed as a potential next major wave in consumer electronics, adoption has been constrained by display systems that are bulky, energy-intensive, or costly. Phosio’s approach enables compact, high-performance displays that can be integrated directly into lightweight eyewear, supporting everyday use of visual AI applications.
Commenting on his appointment, Grenville said Phosio combines a strong technical foundation with a clear vision for enabling mass-market AR/AI glasses. He added that the company’s platform has the potential to reshape how users interact with digital information.
Executive Chairman Joe O’Keeffe said Grenville’s experience in bringing breakthrough technologies to market and navigating strategic partnerships will support Phosio’s customer engagement and commercialization efforts as it moves toward broader market adoption.
