Company history

An establishment of our scientific research and development team roots back to 2001. We developed a groundbreaking methodology to determine an individual intolerance to food products - HEMOCODE™. In over 6 years HEMOCODE™ clinics served to over 150,000 patients to help control their weight. In 2007, the brand HEMOCODE™ was acquired by group of private investors. As a result, there were several clinics opened in Canada. The company entered a venture capital market in Toronto, Canada and in Munich, Frankfurt and Stuttgart, in Germany.

Dr. Konstantin Pronko

We continued our research and development to improve methodology and our approach to testing. We realized a great potential in telemetric contactless methods of telemedicine diagnostics. Our goal was to develop technology that would be capable to record biological parameters of a person, biological feedback and methods to measure vital signs of a human body using available technology. Back in 2008, we did not have the necessary technological means to succeed in our venture. Although we had built medical equipment that worked remarkably well, it was either too bulky or unjustifiably expensive to an end user.

In 2012, we accomplished to create a technology that registers photoplethysmography and measures frequency of arterial pulse, frequency of respiratory movements using an HD camera than not only became affordable but is now a part of any gadget! That marked a beginning of development of today’s true preferences™ technology that we continue to improve.
