About Avive:

Avive Solutions, Inc. (https://avive.life) is a growth stage Automated External Defibrillator (AED) company with a connected response system that is rapidly gaining market share. We are a mission driven team that is quite literally saving lives. Sudden Cardiac Arrest (SCA) is a leading cause of death in the United States, and we are on a mission to change that! We are a dynamic organization that builds elegant, creative solutions to solve complex problems. Ultimately, our mission is for all cardiac arrest victims to have rapid access to life-saving defibrillation.

Avive is taking a fresh approach to addressing this decades-old problem by innovating AED technology, coupled with a first-of-its-kind software platform solution to enable a quicker and more streamlined response to SCA emergencies. We believe that this unique combination of deploying advanced - yet still accessible - hardware, and software, has the potential to revolutionize out-of-hospital cardiac arrest response and massively impact SCA survival rates.
