Sena

Pricing

Two prices, on the page.

You pay once per event, and the number of registrants that Sena messages sets the price. There are no per-seat fees and no annual contract.

What does Sena cost?

Event

3,000€

or $3,000. Up to 500 registrants.

Large event

5,000€

or $5,000. Up to 1,500 registrants, on one day or several.

Bigger than that

A quote

Above 1,500 registrants.

Registrants that Sena messages

The price includes the WhatsApp messages, up to the registrant count of your tier. We send a quote for more than 1,500 registrants, several conferences under one badge, your own WhatsApp number, or your data in one region. For one event in several cities, we price the series as a whole.

Why is the price on the page?

You see the number before the call.

Most organizers expect a number like this behind a sales call. We put it here, so you know it before the call.

Sena

3,000€

The floor. We do not go below 3,000€, because below that price our setup work costs more than the event pays for it.

What do you send us?

Three files and a checkbox.

XLSRegistrant export XLSProgramme XLSSponsor list Phone field and opt-in on your form

A spreadsheet is enough, and an API is better. We build the agent and send the messages. On your side, you add a phone field and an opt-in to the registration form, and you tell attendees about Sena. See what your team does and what you get back.

We run the agent. You keep your tools.

What the fee covers

  • Setup for your event, with your sessions and sponsors
  • The agent your attendees talk to on WhatsApp or the web, before and during the event
  • A WhatsApp message to each registrant with a phone number
  • Intent capture, and the recommendations from it: sponsors, sessions and people to meet
  • A live attendee helpdesk for the duration of the event
  • A post-event report and a follow-up list: what each attendee wanted, where Sena sent them, and who came
  • A WhatsApp number for your event

What Sena does not do

Sena sits on top of the tools you already run. It does not replace them.

  • Registration, tickets and payment. Keep Cvent, Eventbrite, Swapcard, or whatever you use
  • Badges, check-in and on-site scanner hardware
  • Live streams and hybrid infrastructure
  • A lead-retrieval scanner. A scan records that someone walked past. Sena records what they wanted
  • A CRM. Sena produces the intent and the context. Your CRM keeps it

When Sena is the wrong call

Under about 100 attendees, you can introduce people yourself, and you will do it better.

  • Virtual-only events
  • Consumer events and festivals with no sponsor or exhibitor economics
  • If what you actually need is a cheaper event app, or a badge scanner
  • If you need ISO 27001 or SOC 2 today. We can do GDPR, but not those two, yet

The part only you can do

Your promotion decides how many attendees you reach.

The work on your side is small, but it is also the biggest factor in what you get back. At Les Entrepreneurs Haute-Garonne, the opt-in sat on the registration form, and 76% of Speed Business participants took it. Where an organizer added Sena quietly and never announced it, engagement sat near 6%.

Attendees who reply also come more often. At FOST London 2026, registrants who replied before the event had an 18.8% no-show rate, against 43.5% for registrants who stayed silent. Read the no-show data.
