About Fi
Fi is a consumer technology firm focused on developing GPS dog collars that provide location and activity information about dogs. It was established in 2017 in New York City by co-founders Loren Kirkby and Jonathan Bensamoun.
Customers browsing the website can purchase various hardware devices, including Fi's newest release, the Fi Series 3 Plus. The device comes equipped with live GPS tracking, operates on an LTE-M network, features an LED night light, and has an extended battery life of up to three months. In addition, customers visiting the website can access AI-enabled health reports and the Fi App, which supports iOS and Android systems.
Owners of dogs use Fi products to receive real-time updates on their dogs' locations and view daily, weekly, and monthly step counts, resting time, and escape warnings. The system also enables owners to track their dogs' behavioral routines, nutrition, hydration, and sleeping patterns.
The technology firm has received funding from several investment firms, including RRE Ventures, Freestyle, and Longview Asset Management, among others, totaling tens of millions of dollars, according to the company.
