BIG 2026 by Bpifrance

about this room

Bpifrance fills the Accor Arena for BIG, Europe's largest single-day business gathering and comfortably the biggest date in the French entrepreneurial calendar — tens of thousands of founders, executives, investors and public-sector figures across hundreds of sessions from early morning to late evening. The 2026 edition runs under the banner of nerve and daring. Tracks span financing, industry, AI, decarbonisation, international expansion and recruitment, and the scale means the value lies in planning a route through it rather than wandering. Free to attend, and registration goes fast.
