Frequently asked questions
Deeptech startups build companies around scientific, engineering or technical breakthroughs rather than simple software applications. UK deeptech startups often work across AI, robotics, quantum, biotech, semiconductors, advanced materials, space, climate technology and hardware.
The UK is strong in deeptech because of its universities, research institutions, technical talent, spinout activity and specialist investor base. Cambridge, Oxford, London, Bristol, Edinburgh, Manchester and Sheffield are important hubs for science-led and engineering-led startup creation.
Deeptech startups raise funding from angel investors, specialist venture capital firms, university spinout funds, grant programmes and strategic industry partners. They often need more patient capital than software startups because product development, validation and commercialisation can take longer.
Investors in deeptech startups look for defensible intellectual property, strong technical founders, evidence that the technology works and a large commercial market. They also assess whether the company can move from research to repeatable customers without becoming trapped in the lab.
Deeptech startups often take longer to commercialise because they must prove complex technology, build prototypes, protect intellectual property, navigate regulation or integrate with industrial customers. The upside can be significant, but execution risk is usually higher than in standard software startups.
