Your guests handled. You, in control.

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

See how it works

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, follows up with whoever stays silent and scores their risk of not showing up — hands-free for you.

  3. 03

    You decide with data

    Confirmed, pending and who's at risk, in a live dashboard. At the end, you export the list to catering and the door checks guests in by QR.

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.

More than a yes or a no

Synfonix tells you who is at risk of not showing up.

Saying “yes” costs nothing. Real commitment shows in the signals: some are obvious, like a hotel booking, and others the concierge picks up along the conversation. With them it builds a risk traffic light and lets the couple, the quinceañera's parents or your client know who might not show up.

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.

Smart confirmations

Every guest gets a personal WhatsApp message. The agent follows up with anyone who hasn't replied — you chase no one.

24/7 concierge

Schedules, transfers, dress code and lodging: answered instantly, in their language.

Risk indicator

Commitment signals turned into a traffic light for every guest, with a timely heads-up before the event so follow-up happens in time.

No loose lists

One source of truth. No spreadsheets, no WhatsApp screenshots, no double counting.

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.

LiveFree · first year

For your business, not just your events

Smart CRM: no lead goes cold

When someone messages you who isn't a guest at any event, the agent qualifies them right away, gives them the right attention, and alerts the coordinator or the owner once it confirms they're a real prospect.

Free for the first year for founding planners and event coordinators.

  1. 1A potential client messages your number.
  2. 2The agent answers instantly and qualifies the lead.
  3. 3Once it's a real prospect, you get an alert to close the deal.
LiveIncluded

Confirmations with a risk indicator

Not just yes or no: every guest gets a score for how likely they are to miss the event, so you act before closing numbers.

LiveIncluded

24/7 concierge

It confirms, follows up and handles guests' questions and changes at any hour, without you answering every message.

LiveIncluded

QR pass and door check-in

Every guest arrives with their own QR code. Scanning at the entrance works with no internet. Using it is optional.

LiveAtelier

Photo wall

Guests upload their photos, they're projected during the event once approved, and at the end they can be exported as a video.

LiveIncluded

Banquet export

Confirmed guests, menus and dietary restrictions ready to send to catering, with nothing typed twice.

LiveIncluded

Event intelligence

Who confirmed, who is at risk and what needs your judgment, in a single view that's always up to date.

On the day

What gets confirmed on WhatsApp arrives intact at the door.

The same list the concierge confirmed is the one you use to welcome guests and to keep the memories of the night.

Included in every plan

QR pass and door check-in

Every guest receives their own QR code with their invitation. At the entrance, your team scans it and instantly sees who's arriving and how many seats they have.

  • Works with no internet: ideal for beaches, haciendas and places with no signal.
  • Optional: switch it on only if your event needs it.
  • Connected to the confirmations, so the door list is always the right one.
Atelier

Photo wall

Guests upload the photos they take during the event and they appear on screen, live.

  • Moderated by the coordinator, an assistant or the couple themselves: no photo appears without approval.
  • Projected on the day and kept afterwards as a keepsake.
  • At the end, if the couple wants, every photo is exported into a video.

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.
