Connecting the people building the future of UK hard tech.
Mission
Hard Tech UK is a directory of startups, investors, and job opportunities in the UK's hard tech ecosystem. We cover companies working on the physical frontiers of technology — robotics, aerospace, quantum computing, semiconductors, advanced materials, climate tech, biotech, defence, and more.
The UK has one of the strongest deep tech ecosystems in the world, with world-class research universities, a growing base of specialist investors, and an increasing number of startups turning breakthrough science into real products. But finding these companies, the people funding them, and the roles they're hiring for isn't always easy.
That's what Hard Tech UK is for. Whether you're an engineer looking for your next role, a founder scouting the landscape, or an investor mapping the ecosystem, this directory is built to help you find what you're looking for.
What's inside
Hard tech companies across robotics, climate tech, defence, biotech, and more — each with founding details, investors, and open roles.
VCs, accelerators, and grant programmes actively backing hard tech in the UK, with focus areas and portfolio companies.
Engineering and technical roles at UK hard tech startups — software, hardware, robotics, product, and more.
Why hard tech?
Hard tech companies solve problems that can't be addressed with software alone. They build physical products, develop new materials, design novel hardware, and push the boundaries of engineering. The challenges are harder, the timelines are longer, and the impact is often transformative.
The UK is uniquely positioned in this space. With leading research institutions like Cambridge, Oxford, Imperial, and UCL producing world-class talent, and a growing ecosystem of specialist deep tech investors, the sector is scaling fast. From autonomous vehicles in Oxford to quantum computing in Cambridge to fusion energy across the country, the ambition is real.
We believe this ecosystem deserves better visibility. Hard Tech UK exists to make it easier for talented people to find these companies, and for these companies to find talented people.
Who's behind this?
Hard Tech UK is built and maintained by HelenaDW. It started as a personal project to map out the UK's hard tech landscape and grew into a resource used by engineers, founders, and investors across the ecosystem.
The directory is updated regularly with new companies, investors, and job listings. If you know a company that should be listed, or if you'd like to get in touch, reach us at hello@hardtechuk.com.
