Desk data for 2027.

Data and analytics is a London-and-Paris circuit almost entirely built around the “Big Data & AI” and “AI & Big Data Expo” franchises, which run near-identical editions in multiple cities – useful for repeat exposure to the same buyer type across markets.

Every Tier A event in this vertical also carries an applied-AI tag – the two verticals share almost the same audience, so cross-posting content between the data and AI desks is worth doing.

Which is the biggest data and analytics event in Europe?
Big Data & AI World London, at 19,250 attendees.
Are "Big Data & AI World" and "Big Data LDN" the same event?
No – despite the similar naming, they are separate franchises, both held in London.
