 AI at the Core: From Buzzword to Backbone

Across six stages, the “Tech in the Age of AI” theme came to life through thought-provoking panels, demos, and debates.

 Sessions That Stood Out:

• “AI That Saves Lives” — focused on healthcare and public safety

• “AI & Ethics: Regulating What’s Next” — looked at AI governance

• “AI in Climate Resilience” — showcased tech’s role in protecting the planet

AI is no longer a trend — it’s becoming the backbone of UK tech strategy.

Closing Moments: A Celebration & A Call to Action

As Day 3 drew to a close, the atmosphere inside Olympia London was electric with energy and optimism. Oli Barrett MBE, the ever-charismatic host of London Tech Week, returned to the main stage for one final time — not just to celebrate the successes of the past three days, but to challenge the industry to carry forward the momentum. He applauded the thousands of innovators, investors, entrepreneurs, and students who had come together to share ideas and build solutions for a smarter, more inclusive future. Barrett’s message was clear: while the official sessions may have ended, the work is far from over. He urged attendees to return to their cities, companies, and communities with a renewed sense of purpose — to innovate not only for profit, but for people and the planet. The closing ceremony was not a finale, but rather a launchpad for action, signaling that London Tech Week is more than just an event — it’s a movement that lives on in every partnership formed, every pitch delivered, and every bold idea born during the week.
