London Tech Week 2025: AI and Innovation Take Centre Stage
Attracting more than 45,000 attendees across three days, London Tech Week was filled with new government pledges, exciting innovations and announcements left, right and centre.
Billed as the country’s biggest tech event, London Tech Week took place from 9 to 11 June 2025 at Olympia.
Kicking off with an opening address from Sir Keir Starmer, Prime Minister of the United Kingdom, he was then joined by Nvidia Co-Founder and CEO Jensen Huang.
“The UK has one of the richest AI communities anywhere on the planet,” Jensen said. “The deepest thinkers, the best universities — Oxford, Cambridge, Imperial College — amazing startups like and incredible thinkers in computer science.
“There is an incredible research community.
“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 largest AI ecosystem in the world without its own infrastructure’
Speaking off the back of PM Sir Keir’s announcements on new initiatives aimed at boosting the nation’s computing capabilities — including the launch of digital skills programmes for young people — 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, placing digital infrastructure at the centre of the country’s growth ambitions and recognising its essential role in unlocking job opportunities, greater innovation and long-term economic resilience.
“The Prime Minister’s announcement of investing in 20 times more computing is such a big deal.
“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 to develop and deploy AI infrastructure that aims to strengthen the country’s digital economy and security.
Technology Magazine’s London Tech Week highlights
With Jensen Huang emphasising that “because of AI, every industry in the UK will be a tech industry,” London Tech Week stands as a platform for established companies, startups and industry experts — no matter what their specialism — 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 address centred 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 Sir Tim Berners-Lee, best known as the inventor of the World Wide Web.
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.
āIf we donāt watch it, weāre going to double down on the bad stuff, and that will constrain our opportunity to do the right stuff.
āWe come to conferences like this to make sure that everyone appreciates thereās another way of doing it.ā
Technology Magazineās full interview with John Bruce is coming soon.
Other highlights include London & Partnersā presence at London Tech Week, which included bringing an electric BYD London bus to the showcase.
London & Partners ā a partner of London Tech Week ā 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.”
Technology Magazine’s full interview with Janet Coyle, Managing Director, Grow London at London & Partners, is coming soon.
