Turn invitationsinto attendance

Most attendees never add your event to their calendar — they rely on the email, then forget. Stundeo puts a one-click "Add to Calendar" button in every invite. Works with Google, Apple, Outlook and more.

How it works

From invite to calendar in 60 seconds

Pick the one that fits your workflow — or use both.

Single Event
  1. 1

    Create your event

    Enter your event details and generate a shareable link in seconds.

  2. 2

    Share it anywhere

    Paste the link or embed the button in your email, website, or confirmation page.

  3. 3

    Attendees save it in one click

    They click the link, pick their calendar, and it's saved.

  4. 4

    Say goodbye to no-shows

    Once it's in their calendar, they don't forget. That's the whole idea.

Calendar Subscription
  1. 1

    Publish your event calendar

  3. 3

    Every new event auto-appears

    One subscription. Every event you run, automatically in their calendar.

  4. 4

    Full rooms, every time

    No more chasing. No more reminder emails. Just a full room.
