When the grid goes dark, your voice doesn't.
GridVoice is emergency communication for citizens. Prepare before the blackout. Stay connected during it. No cell towers required.
Every communication tool you use requires the thing that just failed.
Cell towers need power. Wi-Fi needs power. Your smart home, your group chats, your emergency alerts. All of it dies with the grid.
Cell towers go silent
Backup batteries last 4-8 hours. After that, your phone is a flashlight with a dead signal.
Internet disappears
No Wi-Fi, no data, no cloud. WhatsApp, iMessage, email, all gone in an instant.
Neighbors become strangers
The people most likely to help you are 30 feet away. But you have no way to reach them.
Government alerts fail too
FEMA and Notify NYC depend on the same infrastructure. When it fails, official channels go dark with everything else.
Two modes. One mission. Never lose contact.
Build your grid before you need it
Set up emergency contacts, join your neighborhood network, create family communication plans. See how many neighbors are ready. Test your connections while the lights are still on.
Pre-crisis modeWhen the grid drops, mesh activates
Your phone becomes a node in a neighborhood mesh network. Messages hop from device to device via Bluetooth and Wi-Fi Direct. No towers, no internet, no infrastructure needed.
Crisis modeCoordinate with your community
Share your status with your building. Check on elderly neighbors. Relay official updates through the mesh. The more people on GridVoice, the stronger the network becomes.
Community resilienceNothing else is built for this.

The grid will fail again. The question is whether you'll be ready.
GridVoice is building the communication layer that should have existed before every blackout, every hurricane, every infrastructure failure. Starting in New York City, because if it works here, it works anywhere.
