# Jared O'Leary

> Jared O'Leary is the Co-Founder and CEO of SirenOpt, a deep-tech startup commercializing PlasmaSens - a manufacturing intelligence platform that uses cold atmospheric plasma and AI to perform real-time, non-destructive materials characterization. A Stanford Chemical Engineering graduate with a Ph.D. from UC Berkeley, O'Leary spun SirenOpt out of his doctoral research with advisor Professor Ali Mesbah in 2022. The platform can generate 213,000 data points per measurement in milliseconds without destroying the sample, targeting battery manufacturing, aerospace, semiconductors, and other advanced manufacturing sectors. SirenOpt has raised $16.1M total, including a $6.5M strategic round led by Hitachi Ventures and JLR's InMotion Ventures in 2025, plus a $2.4M California Energy Commission BRIDGE grant for battery electrode applications.
