Diamond Foundry manufactures single-crystal diamond wafers for high-power electronics, targeting thermal constraints in AI accelerators, EV powertrains, and 5G infrastructure. The tech stack is heavily weighted toward CAD/CAM and manufacturing control (AutoCAD, Solidworks, PLC, Teamcenter, ANSYS, COMSOL) with emerging cloud infrastructure (GCP, AWS, Cloudflare), reflecting a capital-intensive hardware business at the equipment-design and process-scaling stage. Active hiring across engineering and manufacturing—with mid-level seniority clustering—coupled with projects around CVD reactor development and factory expansion, indicates they are ramping production capacity to move diamond substrates from prototype to volume supply.
Notable leadership hires: Reactor Build Center Director, Talent Director
Diamond Foundry, founded in 2013 and based in San Francisco, produces single-crystal diamond wafers and power electronics packages. The company positions diamond as a substrate material superior to silicon for high-power, high-thermal-stress applications in data centers, electric vehicles, and wireless infrastructure. Manufacturing operations span the United States and Spain. The business model centers on converting greenhouse gas into diamond via zero-emission processes, then licensing or selling wafers to semiconductor and power-electronics OEMs. Current operational focus is on scaling production equipment, improving laser processes, and solving equipment reliability and thermal management challenges at the manufacturing floor.
