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.
EUV Tech builds the at-wavelength metrology tools that let the world's chipmakers see what their extreme ultraviolet lithography lines are actually doing. Founded in 1997 and headquartered in Martinez, California, the company supplies reflectometers, pellicle measurement systems, phase-imaging tools and SuMMIT software to every major semiconductor foundry running EUV. In 2023 it raised a Series A led by Intel Capital.
Patrick Naulleau is the CEO of EUV Tech Inc., a Martinez, California-based company leading the development of at-wavelength extreme ultraviolet (EUV) metrology tools for semiconductor manufacturing. With over 25 years of pioneering work in EUV lithography — including helping build the world's first EUV scanner at Lawrence Berkeley National Laboratory and co-developing the SHARP EUV mask microscope — Naulleau transitioned from world-class researcher to industry CEO in 2022. He holds a PhD in Electrical Engineering from the University of Michigan, is a Fellow of both Optica and SPIE, and has authored over 400 publications. EUV Tech raised a $36M Series A led by Intel Capital in 2023.
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.
