Pasching, Austria & Seattle, July 28, 2025 — Tractive, the global leader in GPS tracking and pet health insights, today announced it has acquired Whistle, the connected pet wearable brand owned by Mars Petcare. This strategic acquisition adds Whistle’s customer base and technology assets to Tractive, reinforcing its leadership in the fast-growing pet tech market. Founded in Austria in 2012, Tractive has established itself as the world’s leading provider of smart GPS and health trackers for pets, serving over 1.4 million active users worldwide with millions of devices sold globally.

Whistle customers will have the option to transition to Tractive’s highly-rated platform, named #1 by Consumer Reports and recognized as the top pet tracker on Amazon and top pick by The New York Times Wirecutter. The move gives Whistle users access to Tractive’s latest innovations, including resting heart rate and respiratory rate monitoring, a first in the pet GPS and health tracking category.

“This acquisition is a defining moment for Tractive,” said Michael Hurnaus, CEO and co-founder of Tractive. “It strengthens our U.S. footprint, scales our customer base, and allows us to bring cutting-edge wellness technology to even more pet parents around the world. In the United States, Whistle is recognized as the original pioneer in pet tracking and activity monitoring. Since 2013, Tractive and Whistle have been innovating in parallel, Tractive in Europe and Whistle in the U.S., shaping the future of pet tracking and wellness. Now, by joining forces, we’re combining the strengths of two market leaders to reinforce Tractive’s global leadership and accelerate our mission to improve pet safety and health worldwide.”

Tractive’s smart trackers enable pet owners to locate their animals in real time and monitor comprehensive health metrics including activity, sleep, barking behavior, resting heart rate, and respiratory rate, with millions of health data points analyzed daily to generate valuable insights that ensure safety, wellbeing, and peace of mind for pet owners across North America and Europe.

With the pet industry, and especially connected pet care, growing much faster than overall consumer spending, Tractive is uniquely positioned to lead the future of pet wellness and tracking globally. Its devices offer long battery life, live GPS, health alerts, and now vital sign monitoring—delivered through a seamless subscription model across more than 175 countries.
