CRM-native event platform
You run great events.
We run everything around them.
One app to run every event inside HubSpot — from the sign-up page to the door to the ROI. Registrations, check-in and attendance flow straight to your CRM. Hosted in Switzerland.
Hosted in Switzerland. No credit card to see it.
Swiss-hosted
Your data stays in Geneva, on Infomaniak
HubSpot-native
Statuses sync straight to your CRM
Offline-ready
The door keeps working if the wifi drops
Bilingual
German and English on every surface
Most events still run on a spreadsheet and a clipboard.
Registrations live in one tool, the guest list in another, and the door is a printed sheet. Plenum brings all of it together, wired straight to the contacts you already keep in HubSpot.
Native to HubSpot
Your events live in HubSpot, not beside it
Plenum reads and writes the contacts you already keep in HubSpot — no exports, no second database to reconcile. Registrations and check-in status land in Marketing Events, notes hit the contact timeline, and you build audiences from any list.
- Statuses sync to HubSpot Marketing Events
- Check-in notes on the contact timeline
- Import from any list; signed cancel links for your emails
Run the whole event
From the sign-up page to the door, one app
The core of event management, done properly — the same data all the way through.
Registration
Branded public pages, waitlists and calendar tickets. Sign-ups flow straight to HubSpot.
Check-in & door
QR check-in and a tablet kiosk that keep working offline — even when the wifi drops.
Live roster
One roster showing who is in, who is at risk and who matters most, updating as they arrive.
Analytics & ROI Growth
The only event tool that ties turnout to pipeline
Plenum reads your attendees’ HubSpot deals, so you see cost per head, the spend wasted on no-shows, and the pipeline your events actually influence — across every event, not just one.
- Turnout forecast from each guest’s and company’s history
- No-show risk flags, so you overbook with confidence
- Cost per head and pipeline ROI, cross-event
Built in Switzerland
Your attendee data stays in the country
Plenum runs on Infomaniak in Geneva, one isolated container and data volume per tenant. A bilingual FADP privacy notice is linked from every registration form, by default.

The personal event pass Growth
No app to install. Just a link.
Every registrant gets a token-signed Pass at their own URL. It carries a live check-in QR that flips from Registered to Checked in, live polls and Q&A, opt-in alerts, a personal calendar ticket and, afterwards, feedback and materials.

For your team
Run an event from any device, no install
Plenum is a responsive web app: a laptop at the desk, a phone at the door, a tablet at the entrance, all the same app in the browser, nothing to install. Your team runs the whole event this way. When you want a little more at the door, there is a native iPhone and iPad app too.
- Phone, tablet and desktop, one app
- Add it to your home screen
- Nothing to download to get started
Plenum on iPhone & iPad
You don’t need an app to run the door, the web handles it. But on iPhone and iPad the native app makes it smoother: faster QR scanning, check-in that keeps working if the wifi drops, and an iPad kiosk whose screen stays awake all day.
- Faster, native QR scanning at the door
- iPad kiosk mode, the screen stays awake all day
- Check-in keeps working when the wifi drops

Learn moreWhy we built it
We were running soulTec’s own events on a spreadsheet and a clipboard, so we built the tool we wanted: registration, the door, badges and the analytics in one place, wired to the CRM we already used. Plenum ran its first real events there, and event day got simpler overnight.
