SirenOpt
SirenOpt is a San Leandro deep-tech company turning measurement blind spots in advanced manufacturing into real-time intelligence. Its PlasmaSens platform uses cold atmospheric plasma plus machine learning to non-destructively fingerprint materials on the production line, helping battery, semiconductor, aerospace, and power generation makers see what was previously invisible.

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.
