How VivaTech is different from Slush

• Scale + corporate density: Fortune 500 corporates are more present at VivaTech than at Slush.
• Paris positioning: Proximity to Mistral, Dust, Hugging Face, PhotoRoom, Poolside, Owkin, and the broader Paris AI cluster.
• Government presence: French state + Bpifrance amplify policy-and-capital conversations.

Other 2026 EU events to stack around VivaTech

• Slush (Nov 18–19, Helsinki).

Practical takeaway (founder + investor)

1. Founders: Book investor office hours first, then program your corporate meetings; the investor slots disappear fastest.
2. Investors: Arrive with a thematic filter (defense, AI, climate, fintech) — the scale means you need a funnel.
