Brief the crew, reach every delegate and clear a hall in order

For conferences, exhibitions and one-off events. Your crew talk in voice rooms, delegates and exhibitors join a text list for the day, and the organiser and the venue both get a record of what happened.

Every event brings a new venue, a new crew and a new crowd

There is no time to train people on radios or to ask delegates to install an app. Delegates join a list by scanning a QR code at registration, the crew sign in to the app the day before, and the alert scenarios come ready-made from a pack.

When the event is over, the organiser, the venue and the insurer can all see the timeline and the messages.

  • Venue ManagementA QR code at registration puts every delegate and exhibitor on a text list for the day.
  • Venue VoiceVoice rooms for the crew, security and the venue's own team, with dial-in for anyone without the app.

Typical situations

  1. Clearing one hall

    The people in the hall are texted the route out, everyone else is told to stay where they are, and the replies show who is out.

  2. A suspicious item

    Someone finds an unattended bag under a stand. The area is cordoned off, the crew are told on voice, and nearby exhibitors get a text.

  3. A medical call

    A delegate collapses in a seminar room. The first aid team hear the call straight away, and the timeline records who went and when.

Delegates join at the badge desk

A QR code at registration opens a sign-up page with your event’s branding. Delegates enter their number and receive a welcome text, and you can reach them with a single message for the rest of the event.

Start from the Hotels and conference centres pack

Choose the pack for the kind of venue in the set-up wizard. The conference pack creates the alert scenarios and the procedures for evacuation, invacuation, lockdown, fire and medical, worded for a venue with its own team and a visiting organiser.

An outdoor event starts from the festivals pack instead.

Roles the pack creates

  • Duty manager
  • Reception
  • Security and night team
  • Floor marshals
  • Delegates and exhibitors, by text

Martyn’s Law

A public event with checks at entry, where 800 or more people may be present at once, is a qualifying event in the enhanced tier of the Terrorism (Protection of Premises) Act 2025, and the venue that hosts it may have duties of its own. whoot. supports the procedures for both.
