Foreword

COVVI was founded in 2017 by a passionate and experienced team who wanted to

continue to create leading prosthetic designs.

The human hand is amazing and the level of functionality which can be restored through

prosthetics has historically been very low; but as engineers and designers we see this

as a challenge to continuously improve our designs to meet the needs of users. COVVI

started with a blank sheet of paper and a mission to address some of the most prevalent

deficiencies of current prosthetic hands.

Fast forward to present day and we now have the best looking and most advanced

prosthetic hand in the market.

The COVVI Team
