Meshium is a private off-grid communication system with its own app, firmware, hardware and protocol. Send messages without cell towers, without internet, and without a SIM card — across a network that grows with every new device.
No cell towersNo internetNo SIMNo monthly fees
Modern communication depends on cell towers, the internet, and a working SIM card. The moment any of them disappear, the conversation stops. Meshium is built for the moments in between — and for everything beyond the grid.
Crowded events, remote trails, basements, mountains, disasters — coverage drops exactly when people need to reach each other.
WhatsApp, Signal, iMessage — they all stop the moment your data connection does. There is no fallback for the people closest to you.
Classic radios are not private, not app-based, and not built for the way modern users communicate every day.
Outages, congestion and overloaded networks expose how fragile centralised communication has become.
Meshium combines a dedicated app, custom firmware, purpose-built hardware and a private protocol into a single ecosystem. Together they form a self-expanding mesh that lets people communicate independently — at home, outdoors, in the field, or when central networks are down.
Meshium devices forward messages for each other without being able to read them, so the network can grow organically while private conversations stay private.
Communicate where there is no cellular signal at all.
No WiFi, no data plan, no central server required to talk to people nearby.
Your Meshium device is the network — there is nothing to register, nothing to top up.
Buy the hardware once. The network keeps working as long as you do.
Every Meshium node forwards traffic for the others, extending reach without effort.
Meshium is designed end-to-end as a single integrated product — not a fork or clone of another project.
Meshium is designed to feel as simple as a normal messenger, while running on a completely independent communication layer.
Your phone pairs with a Meshium device over BLE — no SIM, no setup wizards, no accounts to register.
Messages are encrypted locally before they ever leave your phone or your Meshium device.
Nearby Meshium nodes automatically forward the encrypted packet across the network — without being able to read it.
The recipient receives the message through their own Meshium device, where it is decrypted and shown in the app.
Meshium is not just a device — it is a network that grows with its community. Every Mini, L1 and L2 can act as a relay. The more Meshium devices exist in an area, the wider the reach, the more redundancy, and the more reliable the connection becomes.
Meshium’s security architecture is built into the foundation of the system — app, firmware, hardware and protocol — instead of being added on top. The goal is a future-ready design that can evolve as cryptography itself evolves.
Meshium is being designed for the post-quantum era — building modern cryptography in from the start, not as a later upgrade.
Meshium devices forward encrypted packets through the mesh. Relays move messages, not their content.
Private conversations remain encrypted as they travel — also when other people’s devices help carry them.
Each Meshium device is built to identify itself cryptographically inside the network, so peers can recognise who they are talking to.
Firmware updates are planned to be cryptographically signed, so devices can verify the authenticity of every update.
Independent security audits are planned before final release. Security is treated as a core design goal, not a marketing claim.
Note: Meshium does not make absolute security claims. No system can be guaranteed to be unbreakable. Meshium’s goal is a security-first architecture that is openly described, continuously improved, and verified through independent audits before final release.
Meshium is being built as a single integrated system — not a kit of parts. Mini, L1 and L2 are designed for different use cases, but they share the same protocol, the same security architecture, and the same Meshium app.
A small, affordable node that grows the network.
For homes, neighbourhoods and anyone who wants to add a node.
Your personal off-grid communicator.
For everyday users, families, outdoor and travel.
Long range. Bigger battery. Backbone of the mesh.
For communities, events, companies and field operations.
A clean, modern interface for an off-grid network.
For everyone who uses Meshium — iPhone and Android (planned).
Meshium is designed for a wide range of users: from families and outdoor groups to companies, neighbourhoods, makers and developers.
Stay reachable to the people you care about — even where there is no signal.
Reliable communication at the campsite, far from the nearest tower.
Coordinate routes and check in with your group on the trail.
Build a private community network across your street or block.
Keep teams in sync at festivals, races, conferences and gatherings.
Coordinate construction sites, logistics and field crews without depending on cellular.
Build on a real, modern off-grid platform with first-class developer access.
A fallback channel when central infrastructure is down or overloaded.
Meshium is currently moving from working hardware prototypes toward a complete product ecosystem including firmware, app, security layer and production-ready hardware.
We believe the best off-grid network is one that is built openly, with its community, from the very first device.
Meshium currently has functional hardware prototypes used to validate the platform.
The next steps cover firmware, app, security layer, testing and production-ready hardware.
Kickstarter supporters will get early access to devices, firmware updates and the Meshium app.
Backers receive regular development updates — wins, challenges and decisions, communicated openly.
Meshium is being built in phases. Each phase has a clear focus, and progress is shared openly with the community.
Functional hardware prototypes confirm the core platform and protocol assumptions.
Building the Meshium firmware and the cross-platform Meshium app for iOS and Android.
Implementing the post-quantum-ready security layer and running internal testing rounds.
Publicly launching Meshium with early-backer rewards and transparent development updates.
Finalising hardware revisions, suppliers and production processes for the first batch.
Shipping Mini, L1 and L2 devices to early backers and rolling out the production app.
Meshium is being built as a long-term platform for private off-grid communication. The thesis is simple: as the world becomes more connected, the value of independent, community-owned communication grows with it.
Reliance on centralised infrastructure keeps growing — and so does the demand for private communication that does not depend on it.
Meshium combines hardware, firmware, app, security layer and a community-driven mesh network into one integrated platform.
Mini, L1 and L2 cover entry, personal and pro use cases — with room for further specialised devices over time.
Post-quantum-ready security as a foundational design choice — positioning Meshium for a long-term security horizon.
Long-term, Meshium can support a layered business model around the core hardware:
These are directional possibilities, not commitments. The current focus is delivering a high-quality first product line and growing the network.
We are open to conversations with strategic partners and early-stage investors.
Meshium is being built as its own integrated ecosystem, not as a fork or clone of another project. The table below sketches the design intent of Meshium against three common reference points.
| Capability | Meshium | Classic messenger app | Classic walkie-talkie | Other mesh / radio solutions |
|---|---|---|---|---|
| Requires internet | Varies | |||
| Requires SIM card | ||||
| App-based interface | Varies | |||
| Dedicated hardware | Varies | |||
| Automatic relays | Varies | |||
| Private end-to-end communication | Varies | Varies | ||
| Post-quantum-ready security design | ||||
| Scalable, integrated ecosystem | Varies |
This comparison is illustrative and reflects design intent. Capabilities of other systems vary across vendors and versions; “other mesh / radio solutions” refers to general categories rather than any specific product.
