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.
