Everything you own,
on one map.

Car, laptop, tags, anything with a radio. Tether shows you where your things are right now, not where they were the last time you thought to check.

How it works

Three steps, and then you stop thinking about it.

Attach

Pair a Tether tag, or install the app on a phone or laptop. Anything with Bluetooth, GPS or a network connection can report in.

Forget about it

Devices report on movement, not on a timer. A bag sitting still costs almost nothing; a bag in a taxi updates every few seconds.

Open the map

One screen, everything you own, current to within a couple of seconds. Set a zone and get told when something leaves it.

What you can track

If it has a radio, it goes on the map.

Vehicles

Cars, bikes, scooters. Wired to power or running off the tag battery.

Electronics

Laptops, tablets, cameras. Reports over wifi even when locked.

Fleets

Shared team gear with per-person checkout history.

Under the hood

The part I built: the ingest pipeline.

// device → edge → stream → store

ingest.batch({
  window:   "250ms",
  ordering: "per-device",
  onLate:   "reconcile"
})

// 40k msg/s sustained
// p99 write  →  38ms
// six regions, one clock

Pings arrive out of order from flaky mobile networks. Every write is reconciled against device time, not server time.
Batching on a 250ms window cut write amplification by a factor of nine without anyone noticing the lag.
Regional ingest nodes so a device in São Paulo does not round-trip to Frankfurt before its dot moves.
Adaptive reporting: motion sensors gate the radio, which is why a day of tracking costs about one percent of battery.
Back-pressure is the default. When a region degrades, tags queue locally and drain instead of dropping.
