Fi

New York startup behind the Fi smart dog collar, pairing GPS escape alerts with AI that flags changes in a dog's sleep, activity, and eating.

Fi (legally Barking Labs, Inc.) was founded in New York in 2017 by Jonathan Bensamoun and Loren Kirkby, shipping its first GPS dog collar in 2019. The company has raised roughly $45 million across multiple rounds, including a $30 million Series B led by Longview Asset Management with participation from RRE Ventures, Lerer Hippeau, and Freestyle, and has said it expects to cross $100 million in annual recurring revenue. The collar combines GPS location tracking, an escape-detection alert system, and, in more recent hardware generations, on-device AI that flags changes in a dog's activity, sleep, licking, scratching, eating, and drinking that could signal an emerging health issue. In 2026 Fi announced a new collar variant using Starlink's direct-to-cell satellite network to extend location tracking beyond cellular coverage.
