Big Data LDN 2027

Big Data LDN 2027 is a free two-day data, analytics and AI conference and exhibition held at Olympia London, UK, on 22-23 September 2027. The organiser describes it as the UK's leading data, analytics and AI event, and the previous edition drew over 15,000 attendees, 180 exhibitors and 300 speakers. Seminars run across 15 subject-grouped theatres on a first-come, first-served basis, with dedicated theatres for generative and agentic AI, AI context engineering (knowledge graphs, vector databases, RAG), AI/data science/MLOps, and data and AI governance. An 'AI Layer' exhibition zone sits next to the Gen-AI & Agentic AI Theatre so visitors can compare AI vendors in one place. Diamond sponsors include Databricks, Google Cloud and Snowflake, with Microsoft as Innovation Partner.

For a CDO or CIO, Big Data LDN is a zero-ticket-cost way to benchmark the UK data and AI vendor market in two days: Databricks, Google Cloud, Snowflake and Microsoft are on the same floor, and the AI Layer zone puts the AI providers next to each other. The theatre structure maps onto real budget decisions — agentic AI, RAG and context engineering, MLOps, governance and observability, and architecture modernisation — and the VIP Theatre targets senior leaders. Because it is free, it is also the cheapest way to send an entire data team to pick up practice from peers.

• ✓X-Axis and Y-Axis Keynote Theatres
• ✓Gen-AI & Agentic AI Theatre
• ✓AI Context Theatre (knowledge graphs, vector databases, RAG, semantics, context engineering)
• ✓AI, Data Science & MLOps Theatre
• ✓Data & AI Governance & Observability Theatre
• ✓Data & AI Strategy Theatre
• ✓VIP Theatre with executive-level content for senior data and AI leaders
• ✓AI Layer exhibition zone for comparing AI providers
• ✓Lightning Talks Theatre

• ★Free to attend: all seminars in all 15 theatres are open to registered visitors, so a whole data team can go without a ticket budget
• ★Scale for a UK data event: over 15,000 attendees, 180 exhibitors and 300 speakers at the previous edition
• ★Dedicated AI programming split by problem, not vendor: separate Gen-AI & Agentic AI, AI Context, and AI/Data Science & MLOps theatres
• ★The main data-platform vendors exhibit side by side (Databricks, Google Cloud and Snowflake as Diamond sponsors, Microsoft as Innovation Partner), making it a practical vendor-comparison day
• ★First-come, first-served seating means popular sessions fill; plan arrival rather than assuming a reserved seat
