Big Data London is always a highlight of the year for us, and not just for free merch. This year’s event looks bigger and better than ever.
It’s the place where the whole data industry comes together to find inspiration, share challenges (making AI work – anyone?), and see the latest tech solutions from the world’s premier data solutions providers.
Every September, thousands of students, data leaders, practitioners, and innovators descend on London’s Olympia for Big Data London. It’s two days of finding out what others are up to, hearing about the latest tech innovations and, let’s be honest, a bit of eye-rolling about the latest hype cycle.
For us at Oakland Everything Data, it’s more than just another industry event. Big Data London is where we meet our clients, past, present, and future. It’s where the conversations that matter in data and AI happen. And yes, we’ll admit it, stocking up on socks and T-shirts is a nice bonus, too.
But this year, Big Data London feels bigger, bolder, and more important than ever. With AI hype at fever pitch, data leaders are under pressure to deliver real results – and quickly. That’s why we’re so excited about what’s coming up this September.
Why Big Data London Matters
What makes BDL special is its ability to bring the entire data community under one roof. From startups to the biggest global enterprises, everyone is here to share what’s working, what isn’t, and what’s next. It’s a unique opportunity to see cutting-edge solutions, compare experiences, and walk away with a roadmap for delivering value back in the real world.
And while the exhibition floor is buzzing with activity, it’s the conference theatres that steal the show. Packed to the rafters year after year, these sessions offer hundreds of deep dives into everything from governance and data quality to AI ethics and platform modernisation. You need to get in line early to bag a seat, but it’s worth it.
Big Data London 2025 Speakers
This year’s agenda is stacked with over 300 speakers, including data engineers from Netflix, analytics leaders from Google, and strategists from across industries. And of course, Oakland. For the first time since our partnership was announced, Softcat will be there too.
Our very own Andy Crossley, CTO of Oakland, will be joining forces with Alex Pearce, Chief Microsoft Strategist at Softcat, for a no-holds-barred session on why AI isn’t working for everyone and what you can do about it. Their talk, “AI: It’s Going Back to the Future,” will cut through the hype and get real about the foundations every organisation needs to succeed with AI.
Expect honesty, practical lessons, and plenty of myth-busting. If you’ve ever struggled to show ROI on your AI investments, this is the session for you.

Why We Can’t Wait for Big Data London 2025
For us at Oakland Everything Data, Big Data London is like being kids in a sweet shop. It’s not just about the content (though the content is world-class) – it’s about the energy of 15,000+ attendees, the buzz of the exhibition floor, bumping into old friends, and the chance to meet and connect with so many incredible vendors.
It’s also about walking away with ideas – lots of them. From practical ways to scale AI responsibly to swapping war stories with fellow data leaders, we always leave BDL buzzing with inspiration and armed with new thinking to bring back to our clients.
