Find your people. No bars required.
The densest part of any event is the part with no service, and it's where people lose each other. Zeva's messaging and Find run entirely over the mesh, so attendees find friends, groups stay together and your ops team can reach any zone, with no internet anywhere on site.
What Messaging & Find includes
Attendees find friends and get alerts with no service.
Nearby discovery
Opt-in profiles surface the attendees around you. See who's here, what they're here for, and start a conversation.
One-to-one and group messaging
Messages hop phone to phone across the crowd and deliver locally. No carrier, no Wi-Fi, no gateway required.
Find
Guides attendees toward each other using mesh proximity, hop by hop, without GPS, cell towers or sharing a precise location.
Zone broadcast
Operations sends weather holds, crowd instructions and schedule changes to the zones that need them, with delivery confirmation.
Fully local by default
Everything on this page works with zero backhaul. When a gateway is present, messages also reach people off site.
Private by design
Payloads are encrypted end to end. Relaying phones can't read what they carry, and discovery shows only what each person chooses to share.
From the attendee's phone to your systems.
- 1
Discover
Phones running Zeva find neighbors over Bluetooth Low Energy automatically. No pairing or setup.
- 2
Relay
Each message hops across nearby phones toward its recipient. Dense areas elect relay leaders so the mesh stays quiet.
- 3
Deliver
The message lands on the recipient's phone locally, or through a gateway if they've left the site.
