Speed is everything. That’s why we’ve designed an AED that fits in the palm of your hand and one that can be transported anywhere.

  • Size of a lunchbox

The availability of AEDs is crucial in the race against time. By making AEDs more accessible, chances are Joule can win the race to first treatment.

  • Affordable

Every minute matters

The best AED is the one that gets there first

Time is everything when helping sudden cardiac arrest victims. In other words - the best AED is the one that gets there first. We believe in democratising AEDs and making them accessible to everyone. Joule is designed to increase the spread of AEDs and ultimately win crucial minutes.

With the size of a lunchbox and the price of a smartphone, Joule empowers ordinary people to perform life-saving actions.

Setting a life-changing standard

Statistics strongly indicate that it’s about time we rethink how AEDs are designed, used, and communicated to the general public. We believe that Joule will be setting life-changing standards and play a vital role in increasing the survival rate among sudden cardiac arrest victims.
