A VivaTech Paris party: a private event on the Seine for startups and investors

Every June, VivaTech turns Paris into the meeting point of the tech ecosystem: founders, investment funds, large corporations and talent all cross paths within a few days. In this context, the evenings held alongside the show are often where the real conversations begin. But venues and suppliers get booked early, and guests' diaries fill up fast.

We have already published articles on the startup and investor pitch evening and on the fringe evening for a trade show. This one takes a complementary angle: the preparation timeline specific to VivaTech, and the logistical choices that make an evening on a boat stand out from the usual cocktail receptions.

Why host an evening alongside VivaTech

During the show, the days are packed: back-to-back meetings, conferences, stands. In the evening, attendees look for a calmer setting in which to continue the conversation. A private evening lets you bring together your guests, rather than an anonymous crowd: a few targeted investors, potential clients, partners and your team.

A boat suits this need well. A closed group, a space you can move around in, and the Seine drifting past in the background: the setting encourages conversation without the artifice of a staged decor. For international visitors, it is also a way to show them Paris without devoting half a day to it.

The timeline: start early

VivaTech traditionally takes place in Paris in mid-June. The exact dates change from one edition to the next, so check them on the show's official website before you block anything out. Here is an indicative schedule:

• 6 to 9 months before: define your objective (fundraising, client relations, recruitment), the number of guests and the budget. Contact operators to check availability.
• 4 to 5 months before: confirm the boat, the time slot and the mooring. Choose the caterer and the broad outline of the format.
• 2 to 3 months before: send "save the date" messages to key guests, before their diaries become overbooked.
• 4 to 6 weeks before: send out the formal invitations and start tracking replies.
• 1 week before: confirm the final guest list, timings and access instructions.

This time of year is also in high demand for corporate events and summer parties. Our article on booking in peak season sets out the right habits to adopt. The earlier you start, the more choice you will have over the boat and the timing.

Choosing the right boat for your objective

The format depends first on the number of guests and the purpose of the evening.

• A yacht for an intimate dinner with a handful of investors and founders: the atmosphere is private and conversations can be held at a normal volume.
• A péniche (barge) for a larger evening with several areas: a welcome area, a discussion zone, a bar, and possibly a corner for a short speech.
• A moored boat if you would rather stay stable, for example to show a demo or to host guests who do not have their sea legs.

Be sure to allow some margin on the number of guests. In the tech world, last-minute cancellations and unexpected "+1s" are common. A boat slightly larger than strictly necessary avoids the feeling of an overcrowded room.

A format that stands out

To avoid the interchangeable cocktail party, give the evening a light structure:

• A welcome on the quayside with a drink, so that everyone arrives at the same time and boards together.
• A sunset cruise: in June, night falls late, leaving long light on the monuments. Be sure to confirm the exact time when you book.
• A short speech, five to ten minutes, to introduce the team or thank partners, without turning the evening into a conference.
• A walking dinner (substantial canapés and small plates) rather than a seated meal, to encourage people to move around and meet.

If your aim is to introduce people who do not know each other, a short round of introductions or a personal welcome from a member of your team helps a great deal. Our advice on networking on a boat goes in this direction.

Logistics during the show

The show is held in the south-west of Paris, and traffic is heavy when the day ends. Choose a quay that is easy to reach by metro, tram or taxi, and communicate the meeting point clearly, with a map and a number to call. Set a boarding time that takes into account the end of the day at the show: leaving too early means losing guests.

Here are the points to check with the operator:

• the latest boarding time and the actual length of the cruise;
• the equipment available (sound system, microphone, screen) if you plan a speech or a demo;
• wifi or mobile coverage on board, which should not be taken for granted;
• the cloakroom and arrangements for the badges, bags and laptops that guests bring with them from the show;
• fallback options in case of rain.

Looking after guests and measuring the result

A guest arriving after a day at the show appreciates small touches: water and food on arrival, a quieter corner to take a call, and clearly stated return times. Think about the diversity of profiles too: mixing founders, investors and partners adds more value than bringing together only peers.

After the evening, follow up with your contacts within 48 hours, while the memory is still fresh. A short personalised message has more impact than a group email. Have a dedicated team member note down the useful contacts too: it is this follow-up that turns a lovely evening into a concrete result.

In short: set your dates as soon as they are official, choose a boat suited to your format, and keep the evening simple, smooth and focused on conversation. Our team can help you compare the options and secure a slot well ahead of the show.
