CRM-native event platform

You run great events.
We run everything around them.

Plenum takes an event from invitation to debrief: registration, door check-in, badges, a live attendee Pass and the analytics after. Native to HubSpot, hosted in Switzerland.

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 puts all of it in one place, wired straight to the contacts you already keep in HubSpot.

What it does

One platform for every part of event day

Full feature tour →

Registration & public pages

Public event pages with pretty URLs, waitlists with auto-promotion, calendar downloads and social cards that unfurl on every share.

Learn more

Check-in & door kiosk

QR scan check-in, a tablet kiosk with walk-up sign-up, one-tap company group check-in, VIP flags and an offline-resilient queue that never drops a scan.

Learn more

The attendee Pass

Every registrant gets a no-account, token-signed Pass: a live check-in QR, polls and Q&A, event alerts, a calendar ticket and post-event materials.

Learn more

Live view

A real-time wall screen over Server-Sent Events. Counters move the moment a badge is scanned, with arrival pace, VIP highlights and a progress bar.

Learn more

Analytics & reporting

Cross-event scorecards, a who-shows-up audience panel, a public funnel without PII, cost-per-head economics and ready-made report PDFs.

Native to your CRM

Statuses live in HubSpot Marketing Events. Import from any list, sync contact properties and write check-in notes to the contact timeline.

Live view

The room, on the wall, in real time

Put Plenum on the big screen and watch the event fill up. Counters update the instant a badge is scanned, VIP arrivals surface, and an arrival-pace metric tells you whether the doors are keeping up.

  • Check-in activity feed
  • Event-progress bar and pace metric

The attendee Pass

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.
