This is the story of Wales, and its emergence as a global force in compound semiconductors.  A sector quietly supporting the devices, networks, and breakthroughs that will define the world for us all in the next century.

The Big Question

For US technology leaders and global investors, the question is urgent: Where can you find not just capacity, but resilience, innovation, and a talent pipeline ready to take on tomorrow’s challenges?

The Power of the Cluster

Wales’ answer for US investors is both simple and profound: here we out-collaborate, out-innovate, and outpace where it matters most. By building a unique, interconnected ecosystem where academia, industry, and government collaborate as one, Wales has created an environment that is truly open for business; that welcomes new entrants, encourages SME growth, and supports global players alike.

A Legacy of Innovation. A Future of Scale.

Over four decades of expertise and collaboration have made Wales a global hub for compound semiconductor innovation – with 95% of the technology developed here exported around the world.

Today, the cluster is anchored by CSconnected, a partnership of world-leading companies, universities, and research institutions. But the ecosystem is much broader, encompassing a growing constellation of innovative SMEs and startups, as well as global names like Photronics, GE, Vantage, and General Dynamics, all of whom have chosen to be part of the Welsh story.

Wales’ close links to the wider UK and Europe, and deep, long-standing relationship with the US - especially in defence and technology industries make it a strategic location for companies seeking access to global markets. Cardiff and Swansea Universities both feed the ecosystem with cutting-edge research and a steady stream of best-in-class talent.

Agility, Resilience, and Open Innovation

What sets Wales apart is not just its technical expertise, but its ability to move fast, adapt, and collaborate. This tech cluster’s size is its advantage: decisions are made quickly, and partnerships form organically between industry, academia, and government, providing tangible benefits for customers.

Wales’ physical location within the United Kingdom, a “Five Eyes” intelligence alliance country, alongside the US, Canada, Australia, and New Zealand, adds a layer of strategic security for global players, especially those in defence and high-tech sectors. The long-term UK/US relationship is reflected in the presence of major US investors and partners in the Welsh tech ecosystem.

Collaboration at the Core

The Welsh approach is rooted in collaboration at every level.

This spirit of open innovation is evident in the approach to talent, too. From apprenticeships to advanced degrees, the cluster is building a pipeline that spans the full spectrum of skills.

Meeting the World’s Biggest Challenges

The region’s companies are at the forefront of developing compound semiconductors that are faster, more efficient, and more adaptable than traditional silicon. These materials are critical for the next wave of innovation, from ultra-fast data centres to the electrification of transport and the decarbonisation of energy.

The Road Ahead

Wales offers proof of delivery: world-class project sites, a skilled workforce, a culture of innovation, and space for more. The opportunity for growth and collaboration is real, and the movement here is gaining momentum.
