# 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.

- **Role:** Founder & CEO at Thintronics
- **Organizations:** Thintronics, Connora Technologies, Aditya Birla Group
- **Nationality:** American
- **Education:** BS in Biochemistry, College of Charleston, PhD in Organic Chemistry, Columbia University, NIH Postdoctoral Fellow, Organic Materials Science, University of California, Berkeley
- **Known for:** Founded two deep-tech materials companies, with Connora Technologies acquired by Aditya Birla Chemicals in 2019., Pioneered Recyclamine, a proprietary polyamine platform that made epoxy thermoset resins recyclable., Raised approximately $23M for Thintronics to develop next-generation dielectric insulator films.

## Career timeline

- **2011** — Co-founded Connora Technologies to commercialize recyclable thermoset epoxy resins (Recyclamine platform), serving as Co-Founder & CTO.
- **2016** — Connora entered a Joint Development Agreement with Aditya Birla Chemicals to scale up recyclable epoxy amine chemistry.
- **2019** — Aditya Birla Chemicals acquired Connora's Recyclamine technology; Pastine founded Thintronics the same year.
- **2023** — Thintronics awarded a Small Business Innovation Research (SBIR) grant from the National Science Foundation.
- **2024** — Thintronics raised a $20M Series A led by Translink and Maverick (March), later extended to roughly $23M total (August).

## Achievements

- Founded two deep-tech materials companies, with Connora Technologies acquired by Aditya Birla Chemicals in 2019.
- Pioneered Recyclamine, a proprietary polyamine platform that made epoxy thermoset resins recyclable.
- Raised approximately $23M for Thintronics to develop next-generation dielectric insulator films.
