Qromis

What Qromis does

Qromis is a Santa Clara-based semiconductor materials company founded in 2015 that designs and supplies QST™ (Qromis Substrate Technology) engineered substrates for Gallium Nitride (GaN) power device manufacturing. Its core product is a 300-mm QST substrate engineered to support high-voltage GaN HEMT (High Electron Mobility Transistor) devices with breakdown voltages exceeding 650V, addressing cost and yield limitations of legacy 200-mm and silicon-based approaches. The company targets power electronics applications in AI data center power management, industrial power conversion, and automotive power systems, positioning 300-mm wafer economics as a path to displacing silicon in high-voltage power conversion.\n\nQromis operates a technology-collaboration business model rather than a high-volume merchant substrate business: it does not publicly disclose pricing and has no named end-customers, instead co-developing its technology with anchor partners IMEC (process and device R&D) and Shin-Etsu Chemical (substrate supply). The November 2025 IMEC demonstration of a world-record 650V+ GaN breakdown on 300-mm QST material is the principal commercial proof point in the public record, validating the technology but not yet translating into disclosed revenue. The company is privately held, employs 11–50 people, and has one disclosed funding event — a 2018 investment from TEL Venture Capital — with founder Cem Basceri serving as President and CEO.\n\nRevenue mechanics are not disclosed; given the stage of the technology (recent world-record demonstration) and the absence of disclosed sales, the company is best characterized as a pre-commercial / early commercialization deep-tech materials supplier, monetizing through engineering samples, qualification wafers, and collaborative R&D agreements with a small set of strategic partners rather than high-volume merchant shipments.
