Technology is increasingly redefining how individuals train, recover, and maintain their physical well-being. At the intersection of sports science, AI, and immersive technologies, a new generation of connected fitness platforms is emerging, designed not only to track performance but to actively coach, engage and motivate users.
Founded between Austin and Paris, GROWL is a pioneer in this new wave of innovation. The startup has developed a breakthrough AI platform that puts a physical, human-like AI personal trainer and wellness companion directly into the home. By delivering high-stakes accountability and 1:1 connection, GROWL transforms a $175/hour luxury into a 24/7 reality for about $200/month.
A Human-Like Presence in 3 Dimensions
At the core of the product is a sleek, wall-mounted station that incorporates a boxing bag and functions as a life-sized training partner, taking only the space of a wall-shelf. Powered by edge AI, Unreal Engine and 3D motion tracking, the platform offers three distinct dimensions:
1. Coach-Led Classes
Streamed sessions with elite coaches. Users benefit from real-time form feedback and live leaderboards across boxing, strength, yoga, and flexibility, making elite training accessible to all fitness levels.
2. Interactive Games
Immersive environments turn movement into play. By integrating the physical resistance of the boxing bag with digital intelligence, GROWL creates a workout that is as tactile as it is smart.
3. Emma, your AI Coach
Emma provides AI coaching that feels human, physical and alive. With full situational awareness, she engages in real-time conversations, tracking pose, power, and precision instantly to adapt to the user’s specific needs. Over time, she becomes a holistic wellness companion that learns their lifestyle and grows with them.
Elite Outcomes for the Modern Home
Designed for users aged 10 and up, the product transforms fitness into a family activity. GROWL enters a global fitness tech market valued at over $320B, meeting the demand for space-efficient, data-driven solutions. With $4.75M in seed funding from VCs and athletes like former UFC champion Ciryl Gane, GROWL is a hybrid of hardware, gaming and personal training.
The vision is simple: give the power of Personal Training to everyone at-home. For co-founder Léo Desrumaux, combat sports were a way to build resilience and focus. Through Emma, that human spark is now a reality. As AI and motion capture converge, GROWL proves that training is finally becoming a personalized human experience.
