For rescue organizations

Every dog deserves to come home.

PavaFetch is a GPS-free recovery collar built for rescue organizations — no subscription, no cell coverage needed.

Why I Built This

It started with a loss, and a conversation at 2 a.m.

I have been fostering rescue dogs for years. My two Aussies, Millie and Lucy, were my constants through it all. Then came Tucker — a golden retriever foster I fell in love with. I had adopted him through the rescue, but we never got to finalize the paperwork. When I lost Tucker, I stepped away from fostering. Grief has a way of making you pull back from the things you love most.

When I was ready again, I started fostering with Jack Jack's Pack in Austin. One of my fosters, a Great Pyrenees named Daisy, turned out to be pregnant. She went into labor in the middle of the night, and the rescue founder's husband Chas came to help deliver the puppies.

"Since you work in technology, you should build a collar that rescues can actually afford." — Chas, during the 2 a.m. puppy delivery

I could not stop thinking about it. Too many rescue dogs go missing — and most organizations cannot afford the GPS collars and monthly subscriptions that come with existing solutions. That is how PavaFetch started — built from loss, love, and a late-night conversation that refused to leave my mind.

How It Works

Simple. Autonomous. Affordable.

No app to configure. No subscription to maintain. The collar does the work so rescuers can focus on what matters.

🐾

Collar detects

BLE disconnect and motion anomaly triggers lost mode automatically — no human intervention needed.

📡

Beacon activates

A 940nm IR beacon pulses a signal detectable by drone cameras up to 100 meters away.

🚁

Pet found

Any drone operator or rescuer with a phone can locate the pet. No special app or equipment required.

Any drone operator or volunteer with a phone camera can detect the IR signal. Zero setup required.
