We use our expertise in psychophysiology and in design to create wearable technology that changes how you think, feel and behave. Wearables that do, not just sense. Award-winning doppel has been trialled by hundreds of people and its efficacy independently tested. The market size is $6bn in the USA alone and we have over 1300 pre-orders to date. We are developing our next product with Disney and aim to define the future of wearable technology.
