Laura Citron OBE, CEO of London & Partners, the growth agency for the capital, said: “In 2024, London proved its status as a global hub for AI, with record investment flowing into our companies. The numbers say it all – this milestone reinforces our leadership in driving AI innovation worldwide. Frontier innovation, including AI and life sciences, will be at the heart of London's 10-year Growth Plan, to be published next month.” 

Catherine Lenson, COO at Phoenix Court, said: “It is no surprise to see such growing momentum in London. With its combination of world-class talent, access to capital, and a supportive regulatory environment, a new generation of technology companies with the potential to become national, regional, and global champions are being born. From our own neighbourhood of Somers Town, nestled between Kings Cross, St Pancras and Euston stations, we are investing in companies solving real-world problems who are also making sure the benefits of their innovation are being truly distributed." 

Hannah Seal, Partner at Index Ventures, said: “The record-breaking investment in AI startups in 2024 highlights both the immense growth opportunity of the sector and the continued strength of the UK’s talent pool. Index Ventures-backed companies are alone set to create over 2,000 new jobs in the UK this year, thanks in no small part to AI's momentum. So tackling the talent bottleneck must be a top priority for the government to maintain London’s competitive edge on the global stage.” 

Mati Staniszewski, Co-founder of ElevenLabs, said: “The ElevenLabs team was initially attracted by London’s leading universities, as well as the city’s strengths in AI research and safety. London provides access to a deep pool of talent across AI, tech, as well as media and entertainment, which is central to our customer base. London’s status as a creative hub has also enabled us to build valuable partnerships while growing our business.” 

Joshua Blight, Co-founder and CEO at Baseimmune, said: “As a Biotech using AI to design next-generation vaccines, access to exceptional talent, high-end laboratories, and highly developed support networks is key to success. London offers this in huge quantities, making it a simple decision when founding Baseimmune.”
