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.
Thintronics
Thintronics is a San Francisco-based advanced materials company reinventing the humble insulator - the dielectric films that sit between the copper layers of every chip and circuit board. Founded in 2019 by chemist Stefan Pastine, the company designs new insulating materials from the molecular level up, aiming to deliver faster, lower-loss, lower-power interconnects for AI data centers, high-speed networking, and RF/millimeter-wave systems. Its pitch is pointed: challenge the Japanese incumbent Ajinomoto, which has held more than 90% of the dielectric build-up film market for three decades, with a US-made alternative built for the terabit age.
