The UK deep tech sector has seen significant investment growth over the past five years, with £2.3 billion invested in 2022 alone, although still lagging behind the US market leader. The sector's growing popularity is driven by the increasing interest in artificial intelligence and other emerging technologies. Deep tech businesses are heavily reliant on research and development, and founders need to clearly articulate their long-term vision to attract significant funding. However, the UK faces challenges in scaling its deep tech sector, including a lack of confidence among venture capitalists and limited access to talent and resources. To overcome these challenges, initiatives such as the Government's Advanced Research and Invention Agency are needed, as well as changes to university spin-out protocols and the unlocking of pension funds to boost investment in the sector.
