Stefan Pastine

Stefan Pastine is an American chemist, inventor and deep-tech founder who builds materials most people never think about but every device depends on. After earning a PhD in organic chemistry from Columbia and doing postdoctoral work at UC Berkeley, he founded Connora Technologies to make recyclable epoxy resins, which was acquired by Aditya Birla Chemicals in 2019. That same year he founded Thintronics, a Bay Area startup developing next-generation dielectric insulator films for printed circuit boards and semiconductor packaging. His pitch is deceptively simple: the insulator, long ignored while engineers obsessed over transistors, is the overlooked bottleneck for faster, cooler AI data centers - and Thintronics wants to unseat a Japanese giant that has held 90% of the market for three decades.
