Corporate event hackathon invitations: team, API, demo time

Friday, 21:40. You drop the hackathon PDF into the group chat and go to bed. By Saturday morning it sits under a sponsor's newsletter, two memes and one message asking whether Team B still exists. Nobody scrolls back. The first twenty minutes of the day go on working out who is coding with whom.

A corporate event hackathon invitation doesn't have to live in a Downloads folder. A web page opens in the phone browser: no app to install, no attachment to hunt for. One link, and the same link sits behind the QR taped to the door of room 3B.

Corporate event hackathon invitations don't belong in a PDF

A PDF freezes the moment you send it. If the demo moves from 3B to 3C, the file keeps saying 3B and someone has to update a full room by shouting. With a digital invitation there is one version of the truth: the email link, the QR on the door and the screen in the lobby point to the same page. You fix it once.

• Write the teams down. Who codes with whom, on the cover or in a scene, so Saturday starts with the problem and not with pairing people by hand.
• Name the challenge or the API in one short line: public endpoints only, no pre-trained models, whatever your limit is.
• Put the demo time on the cover and in the countdown: 18:30, not 'in the afternoon'.
• Mark the photo of the space as your cover image. A shot of the actual room, cropped into the frame, says more than a paragraph about the venue.

Three things to fix before the first line of code

Team, API, demo time. Those three lines decide whether Saturday runs or stalls. Team: if it isn't written down, people ask, then ask again in the chat, then pair up by chance. API or challenge: the hard constraint belongs on the cover, short enough to read in a lift. Demo time: 18:30 is a different animal from 'in the afternoon'.

All of it goes into the editor in your browser, no installs. One field per detail: label, names, date, phrase, place. A character counter keeps the line readable and the preview updates as you type. Demo time, map, welcome line: you can change any of them after the link has gone out, and the address stays the same. Nobody re-sends anything, because your guests open the version that is live now.

Fix the team, the API and the demo time, and the rest of the hackathon is just code.

Berlin mixes languages at one table

In one Berlin room you'll have teams reading German, teams reading English and two people who switched to English for the internationals. The invitation content can be set per language, and the site itself runs in seven. Venue, address and the hoodie-or-shirt question sit in separate fields, so changing the dress code doesn't touch the date. A photo of the space, already framed, carries the mood better than a line about the atmosphere.

The RSVP list stays inside the invitation

Confirmations land in the invitation itself, in one ordered list you read without scrolling past forty messages of memes. The form questions are yours to set: ask who is staying for the final demo and who is only coming for the closing toast. Guests answer from the phone, in any browser, without installing anything. If your hackathon already has a date, the invitation can be ready today: edit the cover for free in trial mode, unlock every scene when you buy. 29.99 EUR, one payment, no subscription. When the demo time moves at 17:00 on Saturday, you change it and the link is already right.
