Cambridge GaN Devices: Fabless semiconductor company designing energy-efficient GaN power devices for vehicle electrification and data centers.
Cambridge GaN Devices is a fabless semiconductor company based in Cambridge, UK, that designs, develops, and commercializes energy-efficient gallium nitride power transistors and integrated circuits. The organization develops advanced high-electron-mobility transistors that achieve power conversion efficiencies exceeding 99 percent for demanding applications in vehicle electrification, data centers, and renewable energy infrastructure. Operating within a global power electronics market valued at over $30 billion, the firm utilizes strategic manufacturing partnerships with industry leaders like TSMC and ASE for high-volume component production. The enterprise secured $9.5 million in Series A venture capital funding during 2021 to scale its second-generation product lines and support broader commercialization efforts across various international markets. Spun out from Cambridge University after winning a £20,000 business plan competition, Cambridge GaN Devices was founded in 2016 by Dr. Giorgia Longobardi and Professor Florin Udrea.
Cambridge GaN Devices has raised $61.0M across 3 funding rounds.

Cambridge GaN Devices (CGD) is a fabless semiconductor company that designs and develops energy-efficient gallium nitride (GaN)-based power transistors and integrated circuits (ICs), such as its patented ICeGaN platform, which outperform traditional silicon devices in efficiency and compactness.[1][2][3][5] These products serve data centers, industrial inverters, motor drives, electric vehicles (EVs), consumer electronics, and renewable energy applications by solving key challenges in power conversion, including high energy losses and bulky systems, enabling over 99% efficiency and reduced CO2 emissions.[1][3][4][5] Founded in 2016 as a University of Cambridge spin-out, CGD has gained momentum through a $9.5 million Series A funding round in 2021, partnerships like GlobalFoundries for production scaling and Inventchip for reference designs, and new product launches for high-power sectors.[4][5]
CGD emerged from over a decade of research at the University of Cambridge's Electrical Power and Energy Conversion Group in the Department of Engineering.[2][5] Co-founders Prof. Florin Udrea and Dr. Giorgia Longobardi, experts in power semiconductors, spun out the company in 2016 (incorporated October 17) to commercialize their breakthrough GaN-on-silicon technology, initially winning £20,000 in a university business plan competition.[2][5][6] The idea stemmed from applying GaN to enhance silicon transistor processes, addressing global energy consumption and emissions challenges; early traction included product development for switch-mode power supplies and lighting, evolving into high-power applications amid rising demand for sustainable electronics.[3][5]
CGD stands out in the GaN power device market through these key advantages:
CGD rides the GaN revolution in power electronics, fueled by surging demand for energy-efficient solutions amid data center AI growth, EV adoption, and net-zero goals, where GaN's superior speed, voltage handling, and efficiency (vs. silicon) cut losses by up to 50% and enable smaller systems.[1][3][5] Timing aligns with market forces like renewable integration, industrial electrification, and supply chain shifts post-2021 chip shortages, positioning CGD to influence ecosystems through university-rooted IP, global partnerships, and reference designs that accelerate GaN uptake in high-volume sectors.[4][5] As a Cambridge spin-out, it exemplifies UK deep-tech's role in bridging academia to commercialization, fostering sustainable tech amid EU/UK green mandates.[3]
CGD is poised for accelerated growth through expanded ICeGaN adoption in EVs (e.g., Combo tech vs. SiC) and AI data centers, bolstered by fabless scaling and new high-power series.[4][5] Trends like electrification, edge computing, and stricter emissions regs will amplify its trajectory, potentially via Series B funding or acquisitions, evolving its influence from niche innovator to GaN mainstream enabler and tying back to its mission of effortless, planet-preserving power solutions.[3]
Cambridge GaN Devices has raised $61.0M across 3 funding rounds. Most recently, it raised $32.0M Series C in February 2025.
