Cold Plasma Meets Machine Learning: The SirenOpt Story of Solving Manufacturing's Nanoscale Blind Spot

Cold Plasma Meets Machine Learning: The SirenOpt Story of Solving Manufacturing's Nanoscale Blind Spot

Jared O'Leary, Ph.D., is the co-founder and CEO of SirenOpt, and Ali Mesbah, Ph.D. is his cofounder and also his former PhD advisor. Ali is a Professor of Chemical Engineering at UC Berkeley.

 

SirenOpt is a Berkeley spin-out that is solving one of manufacturing's biggest blind spots.

Their PlasmaSens platform uses cold atmospheric plasma and AI to non-destructively inspect thin films and nanomaterials in real-time—catching defects and inconsistencies that traditional methods miss entirely. They're helping manufacturers of batteries, semiconductors, and aerospace components accelerate R&D, optimize production, and dramatically improve quality control.

 

In this episode of Lab to startup, we talk about how the industry currently solves the problems, and how SirenOpt is improving them; Then we deep dive into their technology; the origins of the startup from research at UC Berkeley; customer discovery, especially importance of relationship building and how it is different from just interviewing potential customers; lessons from working with industry; their fundraising journey and many other topics including Jared’s experience working at Theranos.
