Spatial certainty
for the physical world.
Tonebeam places, navigates, and orchestrates devices to centimetre precision — using sound, on the phones people already carry.
01 — Precision, indoors
Sound becomes
a coordinate system.
Where GPS can't reach, a device solves its own position in three dimensions — floor, aisle, height — from the audio around it.
02 — Reliability
It holds where
radio falls apart.
Dense crowds, hard reflections, constant motion. GPS dies indoors; Bluetooth and Wi-Fi drown in a packed room. Sound keeps solving.
03 — Frictionless
No app. No signal.
Still works.
No app to install, no signal to lose: it runs in your app or ours — or straight from a link — and keeps working with no internet at all, because everything happens on the device. Nothing to download, nothing to type.
04 — Scale
From one device
to thousands.
The same layer that places one phone can coordinate a whole venue — light, sound, and motion across the crowd, in sync, with no one entering a seat.
05 — Platform & trust
One layer.
Many surfaces.
The same engine carries identity, access, and data — and it's pure on-device signal processing: nothing recorded, nothing uploaded, no cloud round-trip.
06 — Against the field
Watch the others
lose the signal.

Patent-pending technology
- Navigation & wayfindingIndoor, outdoor, venue-scale.
Turn-by-turn routing where GPS dies — a device solves its own position from the sound around it, then guides people aisle-by-aisle, floor-by-floor.
- Audience orchestrationLight, sound, haptics in sync.
The same positioning layer pixel-maps a whole crowd — thousands of phones become one synchronized display, choreographed to ±10 µs.
- Access & ticketingCheck-in by proximity.
Presence is the ticket. Walk in and you're admitted — no scanning a code, no turnstile, no queue forming at the door.
- Authentication & 2FAPresence as a second factor.
Where you physically are becomes a credential — a second factor that can't be phished, replayed, or faked from another city.
- On-device & privateDeterministic math, no recording.
All signal processing runs locally on the device. Nothing is recorded, nothing is uploaded, and there is no cloud round-trip in the loop.
Built on sound rather than radio, so the dense crowds and hard reflections that break RF barely faze it. It solves on the device itself — app-free and offline, on the phones people already carry.
Short radio pulses give fine ranging, but it needs a UWB chip in every tag or phone — and most phones don’t have one. Blanketing a large space is expensive, and metal-rich, body-packed rooms still scatter the pulses.
Matches a live camera feed against a pre-scanned 3D map of the space. It depends on good lighting, texture, and a clear view — crowds, glare, motion blur, and blank walls break the match — and asking people to wave a camera around raises real privacy concerns.
Measures the round-trip time of Wi-Fi packets to access points. It’s metre-level at best, phone support is patchy and inconsistent, and in a busy room the signal bounces off bodies and structure (multipath), smearing the estimate.
Cheap battery beacons, but distance is inferred from signal strength — a crude proxy that bodies, shelving, and how a phone is held swing wildly. It’s good for “somewhere in this zone”, not for a precise, reliable fix.
Built for the open sky. Indoors the satellite signal is blocked or reflected by the building, so it usually can’t resolve a position at all — it’s the baseline every phone already carries, and precisely where the others have to take over.
In a packed venue, RF scatters off thousands of bodies and the fix drifts or drops. Sound keeps resolving to the centimetre. Hover or tap any row for the why.
