The live map
Your venue.
Not a generic map.
Upload your own plans and annotate them before anyone arrives — assembly points, cordons, gates, service routes. On the day, the live layer draws on top: staff locations, incident pings, and what3words references your stewards can read over the radio. It stays legible when the crowd is the size of a town.
- Upload your own venue plans — stands, concourses, service routes
- Annotate before the event: assembly points, cordons, access gates
- Live layer on top: staff locations, incident pings, what3words refs
- Clustering keeps the picture readable past 2,000 live markers
- Ordnance Survey, OpenStreetMap, and satellite basemaps
Event day, both halves
Your teams talk.
Your crowd hears you.
Radios only ever covered the people on your payroll. whoot. runs both sides of the venue: zone-by-zone voice for staff, and SMS, response pages, and public reporting for the thousands who never installed anything.
Staff — zones, not one big channel.
Stewards hear their zone, supervisors monitor several, and control hears everything — with none of the crosstalk of a single shared frequency.
- A room per zone and per team — stewards, control, medical, traffic
- Push-to-talk from a phone in a pocket or a tablet on the desk
- Presence shows who's listening at every gate before you speak
- Every transmission recorded and transcribed as it happens
The crowd — reachable without an app.
A poster at the gate turns attendees into an alertable, answerable list for the day — and gives every one of them a way to tell you what they're seeing.
- QR posters enrol attendees onto event SMS lists in seconds
- Join late, still covered — mid-alert sign-ups get the live alert
- Two-way SMS: instructions out, "I'm safe" and questions back
- Response pages carry operator updates to every phone — no app
- Anyone can report a hazard from the same poster, photo attached
No fixed infrastructure — a comms operation that stands up in a field
Set-upSame day
The gap
A crowd of seventeen thousand doesn't check email.
It carries seventeen thousand phones. Reach every one of them.
Where it runs
Built for places
people gather.
Arenas & stadia
Zone rooms per stand and gate, steward comms at match-day scale, and a live map that stays readable with tens of thousands on site.
Festivals & events
No fixed infrastructure needed — phones, QR posters, and SMS lists stand up a full comms operation in a field, and pack down with it.
Shopping centres & retail
Security, cleaning, and centre management on separate rooms with one control picture — and public reporting for the things staff don't see.
Hotels & conference venues
Front-of-house calm with back-of-house coordination — and guest-facing SMS that reaches every delegate without an app install.
Theatres & live entertainment
Silent, glanceable coordination during performances; full-volume alerting the moment it's needed.
Campuses & public spaces
Open sites with no gates to count heads at — accountability comes from check-ins, not turnstiles.
