London Tech Week Prioritises AI Infrastructure Growth
London Tech Week was filled with new government pledges, exciting innovations and announcements left, right and centre.
Showcased as the country’s biggest tech event, attracting more than 45,000 attendees, the event took place from 9 to 11 June 2025 at in West London.
The programme started with an opening address from UK Prime Minister Sir Keir Starmer, who was later joined by Nvidia Co-Founder and CEO Jensen Huang and Poppy Gustafsson, Minister of State for Investment of the United Kingdom.
“The UK has one of the richest AI communities anywhere on the planet,” Jensen said during the event. “The deepest thinkers, the best universities — Oxford, Cambridge, Imperial College — amazing startups like and incredible thinkers in computer science.
“It is also the third-largest venture capital investment anywhere in the world. The largest two, the United States and China, is fairly obvious, but the UK is the largest AI investment area anywhere else.
“Between these two ideas, it’s a fantastic place for VCs to invest. The ecosystem is perfect for take-off.”
The journey to forming an AI ecosystem
Speaking about the UK Prime Minister's announcements on new strategies to boost the country's computing capabilities, Jensen emphasised why the UK is an influential player when it comes to tech, and especially AI.
Part of this £2bn (US$2.7bn) funding promise was a £1 billion (US$1.35bn) AI investment announcement, that seeks to place digital infrastructure at the heart of the country’s growth ambitions.
This type of funding could help to unlock job opportunities, innovation and greater economic resilience.
“The Prime Minister’s announcement of investing in 20 times more computing is such a big deal," Jensen said.
“The ability to build these AI supercomputers in the UK will naturally attract more startups, naturally enable the rich ecosystems of researchers here and I think it’s such an incredible place to invest.”
Nvidia is partnering with the UK government to upskill the developer ecosystem by establishing the UK Sovereign AI Industry Forum, a group of leading UK businesses that will develop and deploy AI infrastructure to strengthen the country’s digital economy and security.
Technology Magazine’s London Tech Week highlights
Our sister publication, Technology Magazine, was on the ground during London Tech Week to gather some of the highlights.
The event represents as a platform for established companies, startups and industry experts to converge and propel technology for good.
Sir Keir and Jensen’s address was followed by a session on empowering the future with AI-driven growth and innovation.
Led by Microsoft UK’s CEO Darren Hardman, the talk focused on the power of Agentic AI and debuted a deal with Barclays, which will see 100,000 Microsoft 365 Copilot agents made available for employees.
“With M365 Copilot integrated into Barclays’ colleague productivity tool, Barclays colleagues will enjoy personalised experiences for moments that matter — from small productivity tasks to larger, cross-organisation imperatives and stronger, digital connections with leadership and colleagues globally,” he said.
Joining Darren on the heavyweight speaker line-up included Niklas Zennström, Founder of Atomico, physicist Brian Cox and computer scientist and World Wide Web inventor Sir Tim Berners-Lee.
Joining his Inrupt Co-Founder, John Bruce, on stage, the pair discussed the current drawbacks of the internet and why it is critical for trust and innovation that we put web users back in control of their own data.
Speaking to Technology Magazine after their panel, Agentic Wallets: The Key to Reclaiming a Web that Works for Everyone, John said: “Tim always say about how the web’s evolved, for all its goodness — and think of all the implications of the web — there are some attributes he wishes didn’t exist.
“If we don’t watch it, we’re going to double down on the bad stuff, and that will constrain our opportunity to do the right stuff.
“We come to conferences like this to make sure that everyone appreciates there’s another way of doing it.”
Technology Magazine’s full interview with John Bruce is coming soon.
Other highlights include London & Partners’ presence at London Tech Week, which included bringing an electric BYD London bus to the showcase.
London & Partners — a partner of London Tech Week — has worked with BYD for 10 years, bringing the first EV double-decker to London in 2015.
“We’re at a pivotal stage right now where London — and the UK more broadly — is looking to really lean into science, frontier innovation and AI, quantum and robotics,” she says in her interview with Technology Magazine.
“It’s all about collaboration and companies partnering with other companies, sharing ideas on research and innovation. It’s about collaborating across Europe and making us all stronger.
“To bring everyone together in one place gives us a platform to do that.”
