London Tech Week 2025: Multi-Agent Systems, Coffee Art & the Future of Workflows.

What do a Lord of the Rings reference, AI agents, and a coffee printer have in common? They all took the spotlight at London Tech Week 2025 ☕🤖

From Google Cloud and AWS to rising startups like Novai, this year’s London Tech Week focused on making AI more accessible, easier to understand, and genuinely impactful. The event was not just a showcase of tools but a broader conversation about who gets to use them and how.

One trend that stood out was the growing interest in Multi-Agent Systems. These systems rely on several specialised AI agents that collaborate, divide tasks, and check each other’s work. Instead of relying on one large model to solve everything, the problem is broken into smaller parts handled by different agents. This can improve flexibility and reduce computing costs.

“It’s like in Lord of the Rings: you never have one agent to rule them all.”

That quote came from a speaker describing how each agent in the system took on a specific step in a typical data science task. During a live demonstration, the agents worked together using the pandas library to clean data, explore patterns, and generate visualisations. The process was automated but still designed to support human understanding and decision-making.

There was plenty of serious tech on show, but AWS added a playful touch: a coffee machine that printed customised designs on the coffee foam. It was a small but memorable reminder that innovation doesn’t always have to be serious.

The shift is clear: AI is becoming more usable, and that changes who gets to build.

London Tech Week left me energised and full of questions. The tools are improving, the barriers are falling, and more people than ever can now experiment with what's possible. If you're exploring similar ideas or building in this space, I’d love to connect.
