Invitations used to go out by email, with replies typed into Excel by hand. It was hard to see who had replied and who had not, and some guests slipped through.
We invited 230 guests and 210 confirmed. Every invitation was personal and the reminders went out on their own. We followed every reply in one place, without spreadsheets or paper, and it saved our organisation more than two working days.

18 years of Frka+. An invitation that starts on a billboard.
For eighteen years Frka Plus has been lighting up billboards across Zagreb. For the company's birthday, the invitation opened the same way: a short film in which a billboard lights up over the city, personally for every guest.

Security and GDPR
Your guests, your data. Only you can see them.
A guest list is personal data about your employees and partners. We treat it that way: isolated, in the EU, used only for your event.
Database in the EU
Guest data lives in a database in the European Union, under the GDPR.
Data processing agreement (Art. 28 GDPR)
You are the controller, we are the processor. The data processing agreement is part of our terms.
Isolation at database level
An access rule (Row Level Security) on every table. One client can never see another client’s data.
Access for your team only
The event owner and collaborators they add, up to 10. Sign-in with a one-time email link, no passwords.
Guests see only themselves
Every link carries a random 95-bit key. The guest list is never public.
No ad trackers
No advertising pixels or cookies on the invitation. We never sell the data or use it for ourselves.
Data is not kept forever
After the event the invitation is archived and guests’ personal data is anonymised. You can delete replies earlier.
Only what is needed
Name, contact and reply. One-click unsubscribe, and an unsubscribed address receives nothing more.
We send the data processing agreement, sub-processor list and IT instructions on request: privacy@sealdate.com
Who is behind it
Based in Zagreb. Replies the same working day.

Questions companies ask.
How much do digital invitations for a corporate event cost?
The Start package (a ready-made design in your colours, with your logo) starts at €290 for up to 50 guests, and the Brand package (an invitation built on your identity) at €680. The price rises with your guest count up to 1,500; above that we send a quote. You pay once per event, with no subscription. The full price list and extras are in the table above.
How long does it take to set up a company event invitation?
We send a free prototype with your name the same or next working day. The finished invitation is ready to send 2 working days after you confirm. For events fewer than 5 working days away we work urgently, at +30%.
Can we send invitations from our own company domain?
Yes, for example from events.yourcompany.com, with DKIM signing and DMARC. It is included in Brand and costs €90 in Start. We guide you through the DNS setup step by step.
Is Sealdate GDPR compliant and where is guest data stored?
Guest data is stored in a database in the European Union. You are the controller and we are the processor; the data processing agreement (Art. 28 GDPR) is part of our terms. After the event, guests’ personal data is anonymised. Questions: privacy@sealdate.com.
Do you provide a data processing agreement, and is VAT added?
Yes, the data processing agreement is part of our terms, and we send it with the sub-processor list on request. Prices are final: VAT is not charged because the business is not in the VAT system (Art. 90(2) of the Croatian VAT Act).
Can we check guests in with QR codes at the door?
Yes, QR check-in is included in both packages. Guests receive a personal ticket right after confirming, on the page and by email, and your staff scan it with a phone, with no app.
Will invitations reach Outlook and Microsoft 365 inboxes instead of spam?
We send gradually (150 messages on day one, up to 3,000 a day), with no attachments, one-click unsubscribe and never at night, and we give your IT ready-made guides for Microsoft 365 and Google Workspace. No sender can guarantee delivery, but we do everything the filters ask for.
Can the invitation work in several languages?
Yes. Each guest can receive the invitation in one of 8 languages (HR, EN, DE, IT, SR, BS, ES, FR), chosen per guest. The Start package includes text in 2 languages; each extra language is €49.
Do you work with event agencies and multiple clients?
Yes. The invitation carries the client’s brand and is sent from the client’s domain, and you add the client as a collaborator who sees only their own event. Every next event for the same client is 30% off.
What does a company Christmas party invitation look like, and how many guests can we invite?
Open the three examples above and go through them as a guest. The price list covers up to 1,500 guests, and you import the list from Excel or CSV, up to 2,000 rows at a time. Tehnoguma invited 230 guests to its Christmas party and 210 confirmed.
