Big Data & AI Paris 2026

Repositioned for 2026 towards enterprise decision-makers, with selective visitor qualification.

France's largest data and AI event, run by RX at Paris Expo Porte de Versailles. The 2026 edition is deliberately narrowing: the organisers state they are refocusing on enterprise decision-makers, applying selective qualification to visitor registrations and prioritising business access. Programme runs across three rooms - tech, governance and business - with around 350 sessions. Held under the patronage of the French presidency.

• Three programme rooms: tech, governance and business
• Around 350 conferences and workshops, 200 exhibitors
• Advisory board drawn from AXA, L'Oreal, SUEZ and Credit Agricole

Big Data LDN 2026

Free to attend, Olympia London, over 400 seminars across two days.

The UK's largest data and analytics exhibition, run by RX at Olympia London and free to attend. Over 400 seminars across a two-day programme, with Databricks, Google Cloud and Snowflake as diamond sponsors - the balance between conference and trade show tips towards the latter, and the theatre content is largely vendor-supplied. A separate paid Data Driven LDN track runs alongside for senior practitioners.

• Free entry, over 400 seminars
• Wed 09:00-18:00, Thu 09:00-17:30
• Co-located Data Driven LDN paid track on AI agents, governance and data products

ValkeyConf 2026

One day on Valkey, co-located with the Linux Foundation's Prague week.

A single-day conference on Valkey, the Linux Foundation's fork of Redis, co-located with Open Source Summit Europe in Prague. Programme covers operating Valkey in production, the client ecosystem and the project's divergence from upstream Redis. A contributor summit runs the following day for people working on the project itself rather than deploying it.

Valkey Contributor Summit 2026

Working day for Valkey contributors, the day after ValkeyConf.

A contributor-facing working day for the Valkey project in Prague, immediately after ValkeyConf and inside the Linux Foundation's Prague week. Aimed at people who maintain or patch Valkey rather than operate it, so the shape is roadmap discussion and working sessions rather than a talk track. Attendance expectations were not published at the time of this run.
