Salon de la Data is France's established annual conference for data professionals from both public and private sector organisations, held in Nantes. Now in its 11th edition, the event is volunteer-run, free to attend, and covers the full data practitioner spectrum from data engineering and MLOps to GenAI and data governance. The 2026 edition runs September 22, 8:30-18:00, at the Cite des Congres de Nantes, with remote access available via Swapcard.
The event is organised by a volunteer association with no commercial agenda, which keeps admission free and the sponsor influence limited compared to commercially operated conferences. The CFP for 2026 closed May 24 via sessionize.com/salon-data-2026. Remote access via Swapcard extends reach beyond the Nantes venue. The event serves both the local Pays de la Loire data community and draws attendees from across France.

Executives seeking AI strategy briefings without hands-on data context. Developers with no interest in data infrastructure or ML operations. Attendees expecting a large vendor expo with product demonstrations. Non-French speakers, as the event is primarily conducted in French.
The Cite des Congres de Nantes is the principal convention centre of Nantes, located at 5 Rue de Valmy, 44000 Nantes. It is a modern venue with flexible conference and exhibition space, accessible by tram (line 1, Cite des Congres stop) and located close to Nantes city centre. It hosts regional and national events across sectors.
Association Salon de la Data is a volunteer-run non-profit that has organised the event since its first edition. The association manages the CFP, programme curation, logistics, and partnerships without a dedicated commercial team, relying on volunteer effort from the French data practitioner community.
Eleven editions in, Salon de la Data has become the anchor date for the French data practitioner community outside Paris; the volunteer-run model keeps it free, honest, and free of the vendor capture that afflicts most events at this scale.
