About Us

  • TraXel - LinkedIn

TraXel aims to improve daily lives of people living with chronic conditions. It helps patients stay in control of their health information, make more informed decisions, and track their symptoms using data-driven AI technologies and shared decision making platforms.


TraXel was founded by a group of scientists, patients, and medical doctors to bring a new scientific approach to control and making decisions about health. Our vision is to integrate advanced AI and data-driven technologies with health information to create unmatched health insights. We will help people with chronic conditions to understand how all of the factors in their life may be impacting their conditions:

- what they eat

- what they drink

- how much sleep they are getting

- what medications they are taking

- what type of exercise they do

- what their level of stress is

- where they live

   and much more!


We are interested in building a platform for individuals with chronic conditions and enable them to better receive healthcare and live better. We believe that people should stay in control of their health records so that they can stay on top of their lives and make informed health decisions. Join us now and help us help you!
