About Fi

Our Story

Giving back the freedom to our best friends while keeping them safe and healthy.

Meet Thor – Fi's Chief Dog Officer

Thor entered our founder’s life a little over 2 years ago. Quickly, Jonathan became frustrated being unable to monitor or track him when they weren’t together. More importantly, he always felt torn between giving more freedom to Thor by taking his leash off, or keeping him safe next to him.

But what if we could use modern technology to get the best of both worlds?

Giving back all the freedom to our best friends, and at the same time keeping them safe and healthy. That’s how Fi was built, as the smart dog collar for the next century.

Nothing makes a dog owner happier than seeing their dog truly let loose.

Dogs are happiest when they’re running, swimming, leaping and chasing. We celebrate the spirit of dogs set free to be the wild animals they were meant to be.

We give the freedom back to our dogs by better connecting them to you - their humans.
