Big Data & AI World London 2027

Big Data & AI World is the data and artificial intelligence show within Tech Show London, a business technology expo and conference at ExCeL London. The 2027 edition is set for 10 and 11 March. One Tech Show London ticket gives entry to five co-located shows: Big Data & AI World itself, Data Centre World, Cloud & Cyber Security Expo, DevOps Live and Cloud & AI Infrastructure. The show is aimed at enterprise and public-sector buyers of data and AI technology. Among the job titles the organiser listed as attending in 2026 were chief data officers, data and AI strategists, heads of data science, business intelligence directors, AI engineers and AI architects. Free entry is limited to people who buy or use technology solutions. For Tech Show London as a whole, the organiser cites an audience of more than 19,250 decision-makers drawn from AI, cloud, security and related fields. The 2026 edition ran over two days at ExCeL. Its themes were AI ethics, data governance, model transparency and hands-on frameworks for adopting AI inside large organisations. It featured more than 450 speakers spread over 14 conference theatres, and over 3,000 client meetings were booked ahead of the show through the event's planning tool. According to the organiser, 71% of 2026 visitors specified, influenced or signed off purchasing decisions, and senior leaders represented 63% of the companies attending. Registration for 2027 has not opened yet. The organiser currently offers only a register-your-interest form for updates, and no 2027 ticket prices, agenda or confirmed speakers have been published. The speaker names on the official site come from the 2026 programme and should not be read as the 2027 line-up. For affiliates and media buyers the fit is indirect. The programme targets enterprise data and AI teams, and the published themes include no marketing, traffic or partnership content. The event is most useful for publishers covering the AI vertical who want to see which data and AI vendors are drawing enterprise buyers, and for affiliate networks or in-house teams building data pipelines, attribution models or AI tooling that want to compare suppliers in one hall. Because free entry is meant for buyers, it suits evaluating products rather than prospecting for partners.
