Sena
Sena case study

The floor had 2,996 exhibitors. Every delegate who asked got a shortlist.

VivaTech 2026 · Hub Institute Explorer Tours

Hub Institute runs the official Explorer Tours at VivaTech, two-hour guided walks for C-level executives. Sena picked up where the guide left off, on WhatsApp, for the delegations only.

1,672recommendations made

Drawn from 2,996 exhibitors and 260 sessions. Each one answered a delegate who had just typed a sentence about who they were and what they came to find. 1,309 went to the delegations, 363 to Hub Institute's own guides.

One mark per exhibitor, 3,000 of them. The six picked out are what Sena surfaced for the request above.

Where the tour ends

A guided tour ends, and the executive stands in a hall with 2,996 exhibitors and 260 sessions. The tour covered two hours of it. The rest of the floor is still there, with the reason they flew in.

Hub Institute put a QR code at the end of each tour, and did nothing else. We had no attendee list and sent no message first. Every conversation on this page started when a delegate chose to scan the code.

411 conversations, and Sena started none of them

Most delegates who opened Sena typed something, and one conversation in four ran to three messages or more.

What Hub Institute learned

None of this came from a registration form, because the tours had none.

Next year's floor plan, in the delegates' words

1,569 of the 1,672 recommendations, 94%, sent a delegate to an exhibitor or a startup. The other 103 pointed to sessions and speakers. This event did not include introductions between delegates, and Sena made none.

Demand was uneven across themes. Humanoid and physical robotics led, followed by applied and agentic AI, then retail and luxury technology, data and CRM, fintech, and mobility. That order can shape next year's floor plan and sponsor pitch. Buyers gave it in their own words, with no survey list to pick from.

Delegates worked in two languages, roughly 51% French and 38% English, with the guides almost entirely in French.

Three things from Hub Institute. Sena did the rest.

Hub Institute gave us the exhibitor and session lists and put a QR code at the end of each tour. They also told us which phone numbers belonged to their guides.

Everything on this page came from a code on a card. Add an opt-in to your registration form, push it, and the numbers grow. That push is the one thing we need from you. Les Entrepreneurs Haute-Garonne, a 462-attendee forum, put the opt-in on the registration form and named it in a pre-event email. 76% of participants opted in, and 92% of delivered messages got a reply.
