UK GaN pioneer secures $32m of funding to drive global growth
19 February 2025 
A British developer of high-efficiency gallium nitride power electronic devices, Cambridge GaN Devices (CGD), has raised $32m in Series C funding which it plans to use to expand its operations in Cambridge, North America, Taiwan and Europe.
The company’s founder and CEO, Dr Giorgia Longobardi describes the funding as “a pivotal moment” for CGD. “It validates our technology and vision to revolutionise the power electronics industry with our efficient GaN solutions and make sustainable power electronics possible. We’re now poised to accelerate our growth and make a significant impact in reducing energy consumption across multiple sectors.”
Gallium nitride-based devices represent a breakthrough in power electronics, offering faster switching speeds, lower energy consumption, and more compact designs than traditional silicon-based devices. CGD’s proprietary ICeGaN technology simplifies the implementation of GaN and delivers efficiency levels of more than 99%, leading to energy savings of up to 50% in a variety of high-power applications, including motor drives, electric vehicles and data centre power supplies.
The global GaN power device market is projected to grow at a CAGR of 41%. CGD reckons it will have access to a market worth more than $10bn by 2029. The technology is an alternative to existing devices based on silicon carbide (SiC), promising a combination of high efficiency, miniaturisation and built-in smart functions.
“I’m thrilled to see this funding helping to deliver on customer deals we’ve already closed for CGD’s latest-generation P2 products,” says the company’s senior vice-president of sales, Henryk Dabrowski. “This investment will significantly boost our ability to meet the growing demand for our reliable and easy-to-use GaN solutions.”
The funding round was led by a strategic investor with participation from British Patient Capital (a subsidiary of the Government-owned British Business Bank), and supported by existing investors Parkwalk, BGF, Cambridge Innovation Capital (CIC), Foresight Group and IQ Capital.
Cambridge GaN Devices (CGD) was spun out from Cambridge University in 2016 by Dr Longobardi and Professor Florin Udrea. It aims to shape the future of power electronics by delivering the most efficient and reliable transistors. It says that its GaN transistors and ICs will enable “a radical step change” in energy efficiency and compactness and are suitable for high-volume production. CGD’s technology is protected by a strong IP portfolio.
