Whistle Performance (formerly known as GPS DataViz) has closed a $2 million seed investment round and rebranded, aiming to accelerate global expansion and step up product innovation. The San Diego-based company positions its software as a hub for sports and broader human performance programs, aimed at helping teams and organizations turn complex athlete and workforce data into faster, clearer decisions.
Founder and CEO Marc Kerrest said the new name is intended to reflect the platform’s broader scope, as the company moves beyond its original branding while keeping its focus on performance outcomes. The business says the new funding will support growth in the United States and internationally, while also extending the platform into additional verticals that require high-pressure readiness, including first responders, manufacturing, and the military.
Whistle Performance’s platform aggregates data from multiple inputs, including GPS systems, heart rate monitors, force plates, wellness questionnaires, and testing systems, then applies machine learning and AI to automate analysis and surface insights in seconds. The company argues that this workflow replaces hours of manual effort for coaches and sports science staff, enabling hyper-personalized training, injury risk reduction, and real-time performance management.
The company says it already supports a range of professional and collegiate programs and performance operations, citing customers that include the NFL’s Pittsburgh Steelers, the NWSL’s Orlando Pride, the NCAA’s University of South Carolina Women’s Basketball and Vanderbilt Football, and League One Volleyball. It also highlighted feedback from coaching and performance leaders who described the platform as a way to reduce data complexity and speed up decision-making.

“The irony is not lost on us,” said Marc Kerrest. “In an age captivated by artificial intelligence to drive non-human performance, we are using AI, data analytics, and tech for hyper-personalized training, reduced risk of injury, and real-time performance management of real people, real teams, and real organizations. We believe Whistle Performance is just scratching the surface of the value we can uncover, and the time we can save for coaches and sports scientists, all while expanding to support other verticals that also need to be ready to perform when it matters most, like first responders, manufacturing, and the military.”
