Whistle Performance, recently rebranded from GPS DataViz, builds software that aggregates data from GPS trackers, heart-rate monitors, force plates, wellness systems, and other testing equipment into a single dashboard for players, coaches, and managers. The platform applies artificial intelligence and machine-learning models to generate personalized training recommendations, reduce injury risk, and enable real-time performance management. Today the product is used by professional and collegiate sports programs worldwide and is beginning to gain traction in adjacent sectors such as first responders, manufacturing, and the military. CEO Marc Kerrest leads the company from its base in San Diego, CA. With the newly secured capital, Whistle Performance plans to expand its operations and accelerate product development. While no revenue or user metrics were disclosed, the company positions itself as a data-driven tool for sport science operations and human-performance teams globally.
