Surprise party
A successful surprise party needs an accomplice close to the guest of honour, a guest list that never goes through their usual channels and a solid pretext to get them there on time. Everything else (date, invitations, gift, messages) can be prepared through shared links, out of their sight. Here are the steps in order, and how Filomy helps.
- 2 months before
Pick the date with an accomplice
What makes it complicated
You need to know the guest of honour's plans without asking them, and consult friends and family without a group chat they might see.
With Filomy
A poll shared by link helps choose a date or a venue, anonymously or by name, with a closing date.

Invite people without the guest of honour noticing
What makes it complicated
Family, friends, colleagues: replies come in by text, email and private messages, and one misdirected 'See you Saturday?' is enough to give it all away.
With Filomy
The invitation page takes 2 minutes to create and tracks replies in real time, with the number of plus-ones and custom questions.
Invitations & RSVP → - 6 weeks before
Organise the group gift
What makes it complicated
Gathering contributions from 30 people means tracking every pledge and every transfer, without mentioning it in chats the guest of honour is part of.
With Filomy
The personalised gift voucher names the gift (for example 'A weekend by the sea'), shows a target amount and everyone's words; participants pay the organiser directly.

Secretly collect messages and videos
What makes it complicated
Videos from faraway friends arrive on several messaging apps, in different formats, and everything has to be gathered before the big day.
With Filomy
The online guest book collects messages, photos, videos and voice notes via link or WhatsApp, with no app or account, and can be moderated.

Chase replies and share the D-day instructions
What makes it complicated
You need the last answers and have to remind each guest of the arrival time, where to park and the rule of silence, one by one.
With Filomy
You remind guests who haven't replied in one click and export the list as a CSV file.
Invitations & RSVP → - On the day
The reveal, then the messages on screen
What makes it complicated
Once the surprise is over, building a slideshow from files received from everywhere would have taken whole evenings.
With Filomy
The guest book has a slideshow view to project during the party, and contributions can later be printed as cards or a book.
Online guest book → - After the party
Give a keepsake that lasts
What makes it complicated
Photos of the evening stay on guests' phones and the messages end up forgotten.
With Filomy
Guest book contributions can be printed as cards or a book, to give to the guest of honour.

- On the day, 7:30 pm
- Guests arrive, cars parked out of sight, phones on silent.
- On the day, 8:15 pm
- Julien texts 'Arriving in 10 min'; lights off, everyone in place. At 8:25 pm, the reveal, then the message slideshow.

Discover the boxFrequently asked questions
How do you plan a surprise party without the person finding out?
Choose an accomplice close to them, never use a group they belong to and share everything by link: poll, invitations and guest book. Also ask guests not to post or like anything before the party.
What is a good excuse for a surprise party?
The safest is an ordinary plan that is hard to turn down, suggested by the accomplice: dinner for two, drinks at a friend's, helping someone out. Make sure the excuse fits the outfit, so they don't feel underdressed.
When should the guest of honour arrive at a surprise party?
Allow 45 minutes to an hour after the time given to guests. The accomplice sends the organiser a discreet text 10 minutes before arriving, so the lights can go off and everyone can go quiet.
How many messages does the guest book accept for free?
Up to 50 contributions. Beyond that, it is unlimited with a box or a one-time unlock of €39.90.
