A coral dot at the centre of a dark map sends out widening rings: when a ring reaches a person, that person lights up.

Your event's official channel, on every phone in the crowd.

One announcement, everyone on site. Broadcast, attendee chat and real metrics, inside an area you draw yourself.

Your first event, up to 100 people, is free. No credit card.

Reaching the people already there should not be the hard part.

01

The WhatsApp group half the crowd never finds.

02

The announcement from the stage that the noise swallows.

03

When it is over, how many people actually came? Nobody knows.

Convosphere fixes those three things. Only those. Properly.

How it works

Three moves, and the channel is live.

01

Draw the area.

A centre and a radius. Your event becomes a digital place with a real edge.

02

Whoever is there, walks in.

You can only join the channel from inside the area: the location is verified. No phone numbers, no links to forward, no gatecrashers.

03

Broadcast. And measure.

One broadcast reaches everyone on site in a second. And afterwards you know what happened: arrivals, reads, the busiest spots.

For organisers

The control room in your pocket, the data on your desk.

During the event you run it from your phone. Before and after, from the web dashboard.

Branded channel

Your logo, your colour. The channel is your house.

Broadcast

One message, everyone on site. Scheduled too.

Moderation

Pin, mute, slow mode, ban. A clean room, with named people in it.

Verified entry

Only people inside the area get in. The server checks it, not the app.

Zone heatmap

Where the crowd gathers, hour by hour.

Automatic report

When the event ends, the report arrives on its own.

The channel as the crowd sees it, and the control room as you see it.

For attendees

Free for attendees. Always.

Chat with the people at the event, photos, voice notes and files. Verified identities, no swapping contacts: when the event ends, you decide what stays.

The technology, honestly

Built for the moment the network gives up.

In a packed venue the mobile network saturates: exactly when announcements matter most and get through least. Our Bluetooth mesh chat is in field testing so it works there too. It is on the roadmap, not on sale: we make promises after the tests, not before.
