General information

Diamond Foundry makes diamond wafers and diamond transistors for AI chips and data centers. It also grows lab-created diamonds using chemical vapor deposition (CVD), a vacuum process. The company is based in San Francisco, United States.

Diamond Foundry was founded in 2012 by Martin Roscheisen and Jeremy Scholz. It stays a private company, with about 120 employees. That matters: a small team is trying to change the base material computer chips are built from. Diamond Foundry is an H-1B sponsor.1
