building what's missing.

Scroll

An encrypted mesh communication platform
that works when nothing else does.

No towers. No internet. No permission.
Just you and the network you build.

The Problem

Every other communication system has a single point of failure.

Cell towers go down in disasters. Internet requires infrastructure that someone else owns, operates, and can shut off. Walkie-talkies have zero encryption -anyone with a $30 scanner hears everything.

Satellite phones cost $1,000+ with monthly fees, and still route through corporate infrastructure. Existing mesh devices operate on a single radio frequency -if that one frequency is disrupted, the entire network goes silent.

Nullberry is fundamentally different.

This is not a dev board. This is not a hobby project. This is a communication device designed for people who need to stay connected when infrastructure doesn't exist.

Multi-Transport

7 layers.
Unjammable by design.

When any layer is disrupted, traffic automatically routes through the next available layer. No manual switching. No downtime.

The Nullberry Bush

The network you build.

Four node types. One mesh. Plant Seeds, grow Stems, set Trunks. We build Roots.

Seed $49

Small flat disc, 62mm diameter, 12mm thick. Peel, stick, mesh. Solar powered. Buy in 3-packs ($129).

2-5 miSolar62mm x 12mmPeel & stick
Stem $79

Cylindrical ground stake. Push into soil, pull up the telescoping antenna, walk away. Solar + LiFePO4.

3-10 miSolar + LiFePO4Ground stakeServiceable
Trunk $249

Portable backbone relay. Dual-band LoRa with PA/LNA amplifier. Fold-out solar wings. IR transceiver for jam-proof backbone links.

6-20 mi (30-90 mi LOS)Dual-band LoRaPA/LNAIR backbone
Root Nullberry-owned

Permanent hilltop infrastructure on Nullberry-owned land. 50ft towers, 17dBi antennas, ~200 dB link budget. 250-350 mile backbone range.

You plant Seeds. You grow Stems. You set Trunks. We build Roots.
Together, we grow the Nullberry Bush.

Nullberry OS

An operating system for the end of the world.
And for Tuesday.

Zero-config first boot: choose language, enter name, set PIN. Done. On the mesh in 90 seconds.

Messages

End-to-end encrypted conversations. Store-and-forward delay-tolerant delivery.

Map

Offline OpenStreetMap with mesh peer positions, waypoints, and multi-mode routing.

Nullberry Bush

FindMy-style node manager. See every Seed, Stem, Trunk, and Root in your mesh.

Knowledge

Offline Wikipedia. 6.7 million articles searchable without internet.

Voice

Push-to-talk encrypted voice over any transport layer. Codec2 compression.

Settings

Transport layer management, operational mode switching, identity configuration.

Live Demo

Enter any 4-digit PIN to unlock. Fully interactive.

5 Operational Modes

Full MeshAll transports active, maximum connectivity
Reduced SignatureLimited transmit power, lower detectability
WhisperMinimum power, direct device-to-device only
Silent (RF Dark)All radio off, IR/acoustic/USB only
Dead DropReceive-only, stores messages, delivers on next contact

Open Source

If you can't open it,
you don't own it.

  1. If it's inside the device, it's accessible with one tool.
  2. If it connects, it's labeled and has a pull tab.
  3. If it breaks, you can order the exact replacement part.
  4. If you scan the QR code, you see how to fix it.
  5. If you want to build it yourself, all the files are free.
  6. If you open it, your warranty is still valid.
  7. If a better part exists next year, it drops into the same chassis.
  8. If you never want to open it, it just works.
