Big Data LDN (London) is the UK’s leading free to attend data, analytics and AI conference & exhibition. The two-day event is a hub for the Data Community to learn and share best practice, build relationships and find the tools needed to develop an effective data-driven business.

Data Decoded is more than an event; it’s a movement challenging the status quo of impersonal, profit-driven conferences. Born from a desire to unify the data world, Data Decoded brings together a dynamic community of data leaders and practitioners focused on real-world impact. This high-energy gathering isn’t just about knowledge-sharing; it’s about empowering every business function to harness data for growth and efficiency, no matter the company’s size or structure. Data Decoded stands for democratized data — insights accessible to everyone, not just the upper echelons of business.

It’s data for all.
