About
GROWL is the world's first full-size, human-form AI fitness trainer designed for the home. Unlike screen-based fitness apps or simulations, GROWL physically moves, reacts, and speaks to users in real time — functioning as a fully embodied coach that trains alongside you rather than instructing from a distance. At its core, GROWL is built around boxing as its primary modality, harnessing the raw power of the sport to deliver high-intensity cardio and strength workouts. But its capabilities extend far beyond boxing — users can engage in yoga, strength training, and gaming-style fitness experiences, making it suitable for the whole family, including children. Key features include a conversational AI coach that offers face-to-face motivation and real-time interaction, gamified workout content that makes exercise feel like an immersive game, and AI-driven performance feedback that tracks form and technique with each round. The system uses cutting-edge technology including immersive projection, an interactive touch surface, 3D motion tracking, and seamless home integration. GROWL raised $4.75M in seed funding and has been featured in major press outlets as the future of connected fitness. It targets fitness enthusiasts, busy families, home workout coaches, and anyone seeking a more engaging alternative to traditional gym equipment or standard fitness apps. Whether you want to relieve stress, build confidence, improve boxing technique, or simply stay active as a family, GROWL delivers an experience that is both physically demanding and deeply motivating.
