Sena

Use case: multi-track tech conferences

One agenda per attendee, at a conference nobody can read end to end

At FOST London 2026, more than half of all conversations with Sena asked about the schedule. Six conferences shared one badge and hundreds of sessions. Sena asks each attendee why they came, then gives them their own plan and keeps it current during the two days. You learn who is coming and why, and which sessions they wanted.

Who is this for?

Organizers of tech conferences with parallel tracks, co-located events and a sponsor floor.

Think of a developer festival with six conferences under one badge, or a two-day summit with five rooms at once. Your attendees are engineers, architects and technical leaders. They know what they want to learn. They do not have time to read 200 session titles.

What goes wrong at a multi-track conference?

Attendees miss the talks they came for, and you never find out which ones those were.

The registration form asks for a job title. A job title does not tell you that a staff engineer came for agent governance, or that a founder came to understand API strategy. Your agenda serves everyone the same 200 sessions. The good workshop in the small room stays half empty.

What does an attendee see?

Before the event, they get a plan. During it, they get an answer to "what is on now, for me".

A few days out, Sena asks each attendee what they came for. The attendee answers in a sentence or a voice note. Sena sends back sessions, sponsors worth a visit and people to meet, each with a reason.

On the day, attendees use the same chat as a guide that knows the clock. At FOST London 2026, almost one conversation in four asked Sena what to see next.

It is 11:18. I care about AI agents for banks. What is next for me?

11:18

Two options in the next hour:

11:30, Room 2: who governs the agents in a bank.

11:45, Main stage: MCP in production, a payments case.

Room 2 is the closer one.

Room 2. And what is on after lunch?

Message
On the day, Sena knows the time and the attendee. Session titles are examples.

What do you learn about your audience?

Why people came, in their own words, and what that means for next year.

  • The topic of the year. At FOST London, nine of the ten sessions Sena recommended most were about AI agents, MCP or AI gateways.
  • The sessions nobody asked for. Thirteen sessions never went into a plan. Seven of them were workshops. That is a brief for the next programme.
  • An audience the form missed. 12% of the people who told Sena why they came were there to find a job. Nobody had asked them.
  • Who showed up. Registrants who replied to Sena missed the event at less than half the rate of silent ones, 18.8% against 43.5%. A reply is a strong sign someone will come. It does not prove Sena caused it.

The no-show figures are on our FOST London no-show research. The other sections are on the sample post-event report.

Has this worked at a real conference?

Yes, at FOST editions on three continents this year.

At FOST London 2026, Sena reached 1,135 attendees on WhatsApp and made 1,762 recommendations. 201 attendees replied to the first message, three times more than at any earlier edition. Read the FOST London case study.

At FOST New York 2026, the programme had 195 sessions across five conferences. A quarter of active conversations had one job: filter this programme for me. Read the FOST New York case study.

Not every answer was right. In 17 London conversations, Sena did not answer a question about several time slots at once. We changed the agent after the event.

What does your team do?

Send us your attendee list, your programme and your sponsors. Excel is fine. We set up the agent and send the messages.

Your one job: put a phone field and the opt-in on the registration form. WhatsApp needs an opt-in before a business writes first, per Meta guidance on opt-in. The full list is on what it takes to set up Sena. Prices are on the pricing page.

Frequently asked questions

How do you help attendees choose sessions at a multi-track conference?

Ask each attendee what they came for, then cut the programme to their interests and to the clock. At FOST London 2026, schedule and session questions came up in more than half of all conversations with Sena.

Does Sena replace the event app or the agenda on our website?

No. Keep your app and your agenda. Sena gives each attendee their own short version of it, in a chat.

Do attendees who talk to Sena show up more often?

They show up more often, but we do not claim Sena makes them come. At FOST London 2026, registrants who replied to Sena before the event had an 18.8% no-show rate. Registrants who got the message and stayed silent had 43.5%.

What happens when the programme changes on the day?

Sena answers from your programme, so it is only as current as the programme you give it. At FOST London, the hardest questions were about talks that moved rooms. Send us every change, and Sena gives the new answer.

Does Sena work for a single-track conference?

It works, but you get less from it. The value grows with the number of parallel sessions, sponsors and attendees.

Other use cases

Have a conference in the next six months?

Fifteen minutes. Bring your programme. We show you one attendee's two days, with your sessions in it.
