Big Data LDN 2027 — Olympia London, 22–23 September

Big Data LDN is the UK's flagship gathering for the data, analytics and AI community, taking over Olympia London for two packed days. It combines a full conference programme with a large exhibition, aimed at anyone building a genuinely data-driven business — from senior data leaders and architects to hands-on engineers and AI practitioners. Sessions run across 15 theatres, with more than 300 speakers sharing practical know-how and transformation stories from some of the world's most recognisable brands. On the exhibition floor, global technology vendors sit alongside emerging start-ups, giving visitors room to test-drive tools and compare solutions in person. Popular features include the Women in Data Lounge, the Discovery Zone for early-stage companies, the invitation-only VIP Programme, the Big Data LDN Bookstore and the new AI Layer devoted to next-generation AI solutions. A networking Happy Hour on the first evening gives attendees a relaxed way to catch up after a busy day of sessions. Entry is free with registration. Olympia London is served by its own rail station, Kensington (Olympia), plus several tube lines and local buses, with hotels in Kensington, Hammersmith and West Brompton all within easy walking distance.
