IN-PERSON EVENT | MICROSOFT HQ, LONDON
A PRACTICAL DEEP DIVE INTO A REAL-WORLD COPILOT JOURNEY
Protect Data, Power AI
What does it actually take to roll out Copilot securely? And where do most teams get stuck?
Data governance has a reputation. Necessary, yes. Exciting, not often. But the organisations making steady progress with AI tend to start from a different place. They understand their data, trust its quality, and know how it’s managed and protected. That’s what allows them to move forward with confidence.
Join us at Microsoft HQ in London for a practical, in-person session built around real-world experience. You’ll hear directly from TLT about their Copilot journey. What worked, what needed more thought, and how getting the basics right gave them a solid footing to move ahead.
We’ll also share where data and security challenges tend to appear, and how governance can support progress rather than slow it down. The aim is simple. To help you focus on what matters now, and what can wait.
In this session, you’ll learn:
It’s a small, in-person session designed for open conversation. You’ll be in the room with others working through similar questions, comparing notes and learning what’s working in practice.
Places are intentionally limited to keep it practical and interactive. We’ll close registrations once the room is full.
Date & Time: Wednesday April 22 | 10:00 - 13:30
