Synfonix

Your guests handled. You, in control.

Confirmations, questions, changes and guest follow-up, managed in one place.

The part nobody enjoys

Running an event is complicated enough already.

  • Chasing confirmations one by one.
  • Answering the same questions a hundred times.
  • Updating lists that change every single day.
  • Finding out too late that a plus-one changed.
  • Never really knowing who will show up.
  • Living inside WhatsApp at any hour.

Your guests need answers. You need to handle hundreds of details. Synfonix takes that conversation off your hands so you can focus on what actually needs your judgment.

How it works

Three steps and follow-up stops being your job

  1. 01

    Upload your list

    Names, phone numbers and groups. No strange formats: if it's already in a spreadsheet, it works.

  2. 02

    The agent confirms

    It messages every guest, answers questions and follows up with whoever stays silent — hands-free for you.

  3. 03

    You decide with data

    Confirmed, pending and no-show risk in a live dashboard, ready to close numbers with the venue.

Concierge

A concierge always available for your guests.

From a transport question to a change in their RSVP, guests get help without waiting for you. Live today on WhatsApp and web; the other channels are built into the architecture, ready to switch on.

Primary

WhatsApp

The main channel in Latin America. Confirmations, reminders and questions in the same chat they already use.

Web invitation

The visual experience of the event, with a personal guest pass and confirmation wired to the same agent.

Email

For corporate and hotel lists, where email is still the formal path.

SMS

A fallback for guests off messaging apps, or for last-minute reminders.

AI voice call

For guests who only confirm by talking. The agent places the call, with a natural voice.

Voice notes and languages

It understands audio, transcribes it and answers in the guest's language — no translators in between.

Powered by artificial intelligence.

Know what's happening without asking

Synfonix tells you where to put your attention.

It doesn't just automate: it filters the noise and surfaces the cases that actually need you to decide.

If it's your event

You get to enjoy the planning: nobody asks you the same question three times, and you know who's coming, what they eat and how they arrive.

If you produce it for a client

Fewer WhatsApps, fewer spreadsheets, fewer last-minute loose ends. Your clients reach the big day calm — wedding, Sweet 15 or corporate.

What Synfonix does

Fewer open loops for you, not more software

Everything shares the same guest list, so nothing gets duplicated and nothing gets lost between chats.

Live

Smart confirmations

Stop chasing guests. Synfonix handles confirmations and follow-up for you.

Live

Guest concierge

Your guests ask whatever they need, whenever they need it, without you answering every message.

Live

Follow-up

Who confirmed, who is still pending and who needs attention, always up to date.

Live

Changes and exceptions

Guests update their own details without every change turning into a new task for you.

In beta

Event intelligence

A clear view of what's happening with your guests and what actually needs your judgment.

Same engine, different event

Not just weddings.

Wherever there's a guest list to confirm, Synfonix works the same. The tone of the message changes, the system doesn't.

Destination weddings

Guests across cities, time zones, flights and transfers. The hardest case — and where it shows the most.

See the page for wedding planners

Sweet 15 & social events

Long family lists, confirmations by group and last-minute changes without chasing anyone.

Corporate & hotels

Conventions, gala dinners and groups: formal email confirmation, WhatsApp follow-up and final numbers on time.

Produced events

Anniversaries, openings and private experiences where the final count drives catering, furniture and transport.

Also from Synfonix

Digital invitations, for that same event.

Cinematic, bilingual designs — the channel where your guests receive everything.
