A unique digital therapeutic
Physical Activity made easy to program.
Incentivising adherence to sustain engagement.
Exercise. It’s a powerful thing. It can improve our physical and psychological health. It can manage, treat, and even prevent certain conditions. For many, it’s a life-changer.
For years, research has shown the benefits of physical activity, but we’ve never had the tools to release its full potential. Most healthcare professionals have been able to give recommendations, but not personalized programs. Provide advice, but not incentivise or monitor real-time adherence. There has never been a seamless way to use exercise as a targeted and engaging treatment for all.
EXI makes exercise programs accessible, combining decades of scientific knowledge with pioneering technology to create the future of AI-powered healthcare. Our intelligent platform allows healthcare and fitness professionals to create tailored programs in a way that’s easy, effective, and scalable. By layering on sophisticated motivational systems, rewards and incentives, we can achieve lasting behavioral change for all, including the people who need it the most.
This isn’t just exercise. This is EXI: Exercise Intelligence.
To help millions accelerate the achievement of their most important health goals.
A world where the prevalence & impact of long-term health conditions is dramatically reduced thanks to the seamless integration of physical activity & healthcare.
